+# Issue #667 - Schema Diff and Migration/Backfill Plan
+
+## Scope
+This document captures the implemented schema/model delta for #667 and the migration/backfill approach for existing records.
+
+## 1) Schema Diff (Existing -> Target)
+
+### MeasureCatalog
+- Added `business_definition` (nullable)
+  - Domain: `MeasureCatalog.BusinessDefinition`
+  - Data model: `MeasureCatalogDataModel.BusinessDefinition`
+
+### Measure
+- Added `business_definition_override` (nullable)
+  - Domain: `Measure.BusinessDefinitionOverride`
+  - Data model: `MeasureDataModel.BusinessDefinitionOverride`
+
+### MeasureIntegration
+- Added SQL lifecycle metadata (all nullable unless noted):
+  - `definition_version`
+  - `definition_hash`
+  - `previous_definition_version`
+  - `previous_definition_hash`
+  - `requires_template_regeneration` (bool, default false)
+  - `regeneration_reason_code`
+  - `sql_template_hash`
+  - `query_artifact_ref`
+  - `sql_template_generation_status` (string enum, default `Pending`)
+  - `last_sql_template_generated_at`
+  - `last_generation_error_code`
+  - `last_generation_error_stage`
+  - `last_generation_error_message`
+
+### ConnectionConfiguration
+- Added external reference model fields:
+  - `external_provider`
+  - `external_connection_id`
+  - `workspace_context`
+- Added validation diagnostics:
+  - `last_validation_error`
+
+### SystemMeasureConfig
+- Added intent/constraint metadata:
+  - `ai_topic`
+  - `system_constraints_json`
+
+## 2) Index/GSI Impact Assessment
+- No new query paths were introduced in #667 that require immediate GSI additions.
+- Existing GSIs remain valid:
+  - `purposepath-system-measure-configs`: `system-index`, `measure-catalog-index`
+  - `purposepath-connection-configurations`: `tenant-index`, `system-index`
+  - `purposepath-measure-integrations`: `measure-index`, `connection-index`, `tenant-index`
+- Pulumi updates are **not required** for this slice because DynamoDB is schemaless for non-key attributes and no new key/index access patterns were added.
+
+## 3) Migration and Backfill Plan
+
+### 3.1 Safety
+- Do not delete or rewrite legacy credential fields in-place.
+- Keep old fields readable while new external-reference fields are populated.
+- Run migration in idempotent batches by tenant.
+
+### 3.2 Backfill Steps
+1. `MeasureCatalog`
+   - For records with empty `business_definition`, leave null.
+   - Optional enrichment can be done later from curated catalog metadata.
+
+2. `Measure`
+   - Set `business_definition_override` only when explicit tenant/measure overrides exist.
+   - Default remains null.
+
+3. `MeasureIntegration`
+   - Initialize defaults when fields are missing:
+     - `requires_template_regeneration = false`
+     - `sql_template_generation_status = Pending`
+   - Keep lifecycle hashes/versions null until first template generation flow runs.
+
+4. `ConnectionConfiguration`
+   - Legacy records with encrypted credentials:
+     - retain `encrypted_credentials` unchanged
+     - set `external_provider` / `external_connection_id` only when mapping to known CData references is available
+   - Non-mappable legacy records:
+     - set `validation_status = Invalid`
+     - populate `last_validation_error` with remediation hint
+
+5. `SystemMeasureConfig`
+   - Initialize `ai_topic` and `system_constraints_json` as null for existing records.
+   - Populate incrementally during system-specific configuration updates.
+
+### 3.3 Verification
+- Build and domain tests must pass after migration tools/scripts are introduced.
+- Spot-check by tenant:
+  - query active connections and verify external-reference fields are either valid or explicitly flagged.
+  - query measure integrations and verify lifecycle defaults are present.
+
+## 4) Rollout Notes
+- Deploy code first (backward compatible).
+- Run backfill in dev stack.
+- Validate read paths and integration execution behavior.
+- Promote to higher environments after verification.

+**Status:** Draft for Validation  
+**Ownership Model:** Shared between PurposePath backend project and AI backend project  
+**Primary Scope:** Contract and architecture requirements for AI-driven SQL template generation and measure integration lifecycle
+
+---

+11. [Shared Delivery Governance](#11-shared-delivery-governance)
+
+---
+
+## 1. Intent and Objectives
+
+### 1.1 Intent
+Establish a clear, testable, and contract-first integration model between PurposePath and AI services for SQL template generation, measure data retrieval orchestration, and deterministic publication of measure outcomes.
+
+### 1.2 Objectives
+1. Define a stable, versioned event contract between systems.
+2. Ensure deterministic and idempotent processing from generation request to terminal outcome.
+3. Separate business intent, system constraints, and runtime lifecycle responsibilities.
+4. Improve reliability, observability, and governance without coupling to implementation details.
+5. Provide measurable completion criteria aligned with epic and issue scope.
+
+---
+
+## 2. Scope
+
+### 2.1 In Scope
+- Contract requirements for EventBridge events used for SQL template generation.
+- Requirements for intent resolution hierarchy and parameter semantics.
+- Requirements for idempotency, terminal outcome guarantees, and replay safety.
+- Security, performance, and operational design constraints.
+- Cost model and expected cost controls.
+
+### 2.2 Out of Scope
+- Internal code structure, class design, and framework-specific implementation.
+- Infrastructure-as-code templates or deployment runbooks.
+- UI behavior details.
+- Non-integration AI topics unrelated to SQL template generation.
+
+---
+
+## 3. Source Artifacts and Traceability
+
+This requirements document consolidates scope and decisions from the following planning artifacts:
+
+- Epic #665: Measure integration refactor epic
+- Issue #666: Architecture and contract baseline
+- Issue #667: Schema and data model changes
+- Issue #668: Connection model and provider-facing metadata alignment
+- Issue #669: Payload and event contract implementation scope
+- Issue #670: Worker/orchestration behavior and idempotency
+- Issue #671: API/EventBridge specification alignment
+- Issue #672: Legacy cleanup and deprecation scope
+- Issue #673: Validation, rollout, and completion criteria
+
+> Requirement IDs in this document map to one or more of these issues for completion tracking.
+
+This document is also a shared contract artifact for the AI backend project. The AI project may track equivalent scope with separate issue IDs in a different repository.
+
+**Traceability rule:** requirement completion is considered final only when linked backend-side and AI-side tracking artifacts are both marked complete.
+
+---
+
+## 4. Architecture Requirements
+
+### 4.1 Architectural Principles
+**AR-001** Contract-first design: all cross-system interactions must be defined by versioned contracts prior to release.
+
+**AR-002** Separation of concerns:
+- business intent definition
+- system-specific constraints
+- runtime lifecycle and state
+must remain logically distinct.
+
+**AR-003** Deterministic processing: identical inputs and definition versions must produce reproducible contract outcomes.
+
+**AR-004** Backward-compatible evolution: contract changes must be versioned and non-breaking by default.
+
+### 4.2 Logical Architecture Boundaries
+**AR-010** The integration domain must expose a dedicated contract surface for SQL template generation events.
+
+**AR-011** AI systems must consume request events and emit exactly one terminal event per generation cycle.
+
+**AR-012** Runtime state and terminal outcome identity must be keyed by a stable generation identity.
+
+**AR-013** Solution design must conform to `.github/DEVELOPMENT_GUIDELINES.md` architectural boundaries:
+- controllers remain boundary-only and delegate via MediatR
+- domain layer remains pure and free of infrastructure concerns
+- contracts/interfaces required by domain are defined in domain-facing boundaries
+- cross-layer dependencies must follow Clean Architecture direction
+
+**AR-014** Any architecture deviation from `.github/DEVELOPMENT_GUIDELINES.md` must be explicitly documented, risk-assessed, and approved before release.
+
+### 4.3 Intent and Parameter Architecture
+**AR-020** Intent precedence must be:
+1. measure-level override intent (when present)
+2. catalog-level canonical intent
+
+**AR-021** System-level configuration defines allowed parameter schema and constraints, not business intent text.
+
+**AR-022** Runtime integration state owns lifecycle metadata (definition version/hash, regeneration state, generation outcomes).
+
+---
+
+## 5. Contract Requirements (AI ↔ Integration)
+
+### 5.1 Contract Version and Event Set
+**CR-001** Contract version 1.2 is the baseline for inter-system event exchange in scope.
+
+**CR-002** Required event types:
+- integration.sql.template.generate.requested
+- integration.sql.template.generate.completed
+- integration.sql.template.generate.failed
+
+### 5.2 Envelope and Identity
+**CR-010** Every event must contain the standard EventBridge envelope fields.
+
+**CR-011** Every event detail must include a common identity block containing event version, provider, correlation identity, generation identity, tenant identity, integration identity, idempotency key, and canonical definition version/hash.
+
+**CR-012** Definition identity must exist in a single canonical location in the payload.
+
+### 5.3 Requested Event Requirements
+**CR-020** Requested events must provide:
+- resolved intent template and period-window strategy
+- source/system connection context needed for contract execution
+- allowed parameter schema and selected parameter values
+- regeneration flag
+- SQL policy constraints, including required placeholder style and max rows semantics
+
+**CR-021** The contract must define max rows as final result-set row count.
+
+### 5.4 Completed Event Requirements
+**CR-030** Completed events must provide:
+- success status
+- parameterized SQL template
+- template hash
+- binding schema
+- explicit applied parameters list
+- explicit ignored parameters list with enum reason
+- validation outcome data
+- generation timing metadata
+
+**CR-031** Completed events must include provider and traceability connection fields for downstream diagnostics.
+
+### 5.5 Failed Event Requirements
+**CR-040** Failed events must provide:
+- failed status
+- stable error code and error stage enums
+- retryability flag
+- sanitized failure message
+- attempt and duration fields
+
+**CR-041** Failed events must support optional retry-after, provider error code, and structured validation failures.
+
+### 5.6 Enum Governance
+**CR-050** Error codes, error stages, ignored parameter reasons, and validation failure codes must be governed by canonical enums.
+
+**CR-051** Enum changes require versioned contract governance and compatibility review.
+
+### 5.7 Compatibility Rules
+**CR-060** Terminal events must return the same definition version/hash from the requested event.
+
+**CR-061** Runtime binding expectations (if present) must be compatible with emitted parameter binding schema.
+
+**CR-062** SQL placeholder style in emitted template must match policy-defined style.
+
+---
+
+## 6. Functional Requirements
+
+### 6.1 Lifecycle and Regeneration
+**FR-001** The system must initiate SQL template generation when structural query-shaping changes are detected.
+
+**FR-002** Value-only parameter changes must not require template regeneration by default.
+
+**FR-003** Regeneration state must be explicit in request contract.
+
+### 6.2 Idempotency and Terminal Behavior
+**FR-010** At most one terminal event may exist for a generation identity.
+
+**FR-011** Exactly one terminal outcome (completed or failed) must be produced per generation identity.
+
+**FR-012** Duplicate or replayed terminal events must be safely recognized and handled without data corruption.
+
+### 6.3 Validation and Policy Enforcement
+**FR-020** Completion is valid only when policy and validation checks pass.
+
+**FR-021** SQL templates must remain parameterized and must not interpolate user-provided values.
+
+**FR-022** Forbidden operation policy must be enforced before successful terminal publication.
+
+### 6.4 Traceability and Auditability
+**FR-030** Contract events must support end-to-end correlation via correlation and generation identities.
+
+**FR-031** Contract events must include sufficient context for post-incident diagnosis without requiring implementation-specific logs.
+
+---
+
+## 7. Security Requirements
+
+### 7.1 Data Protection
+**SR-001** Event payloads and logs must not expose credentials, secrets, or raw sensitive tokens.
+
+**SR-002** Failure diagnostics must include only sanitized fields approved for cross-system transport.
+
+### 7.2 Access and Trust Boundaries
+**SR-010** Producer and consumer trust boundaries must be explicit and validated through contract version controls.
+
+**SR-011** Event sources and detail types must be constrained to authorized producer identities.
+
+**SR-012** Tenant isolation is mandatory: every contract event and lifecycle transition must be scoped and validated by tenant identity so cross-tenant access, processing, or publication cannot occur.
+
+**SR-013** Tenant identity used for processing must be consistent across request and terminal events; identity mismatch must result in rejection.
+
+### 7.3 Integrity and Non-Repudiation
+**SR-020** Definition hash and template hash must be used for integrity checks across systems.
+
+**SR-021** Terminal event acceptance must verify identity consistency with originating request.
+
+---
+
+## 8. Performance and Reliability Requirements
+
+### 8.1 Performance Targets
+**PR-001** Generation workflows should complete within an operational target window appropriate for asynchronous orchestration (target: low-seconds to low-minutes under nominal load).
+
+**PR-002** Contract validation overhead should remain small relative to total generation latency.
+
+### 8.2 Reliability Targets
+**PR-010** Terminal event delivery reliability target: 99.9%+ successful terminal publication under normal operating conditions.
+
+**PR-011** Transient failure handling must support bounded retries with explicit retryability semantics.
+
+**PR-012** Non-retryable failures must fail fast with stable error taxonomy.
+
+### 8.3 Observability Requirements
+**PR-020** Metrics and logs must support tracking for:
+- generation throughput
+- success/failure rates
+- retry rates
+- terminal latency distribution
+- contract validation failures
+
+**PR-021** Observability signals must be keyed by generation and correlation identity.
+
+---
+
+## 9. Cost Estimate
+
+### 9.1 Estimation Approach
+This estimate is a planning-level range based on expected event volume, AI generation frequency, and validation overhead. It is not a billing commitment.
+
+### 9.2 Cost Drivers
+1. Event traffic volume (request + terminal events)
+2. AI generation and validation calls per generation cycle
+3. Retry frequency on transient failures
+4. Storage and retention for lifecycle metadata and audit traces
+5. Observability ingestion and retention
+
+### 9.3 Relative Cost Profile (Planning)
+- **Low volume rollout:** low operational cost profile
+- **Moderate scale rollout:** moderate profile driven mostly by AI generation invocations
+- **High scale rollout:** AI + observability become primary contributors; retry discipline materially affects cost
+
+### 9.4 Cost Control Requirements
+**CO-001** Regeneration must only occur when required by structural changes.
+
+**CO-002** Retry policy must differentiate transient from permanent failures to prevent waste.
+
+**CO-003** Event payloads should include only contract-required fields to control transport and storage overhead.
+
+**CO-004** Retention windows for diagnostics and traces must be policy-driven and periodically reviewed.
+
+### 9.5 Baseline Monthly Planning Range (for validation, non-binding)
+Assumptions:
+- 10k to 100k generation cycles per month
+- 2-3 events per cycle
+- low retry rate under healthy operation
+
+Planning range:
+- **Lower bound:** hundreds of USD/month
+- **Mid range:** low thousands USD/month
+- **Upper planning bound:** several thousands USD/month at higher volume/observability settings
+
+> Final budget should be re-estimated after pilot telemetry is collected.
+
+---

-# Admin AI Specifications - LLM Topic Management
-
-- Last Updated: February 13, 2026
-- Version: 3.1
-
-## Revision History
-
-| Date | Version | Description |
-|------|---------|-------------|
-| 2026-02-13 | 3.1 | Synced spec to implementation for admin model responses, topic auth, topic type terminology, and conversation extraction config. Updated `/models` response shape (`ApiResponse[LLMModelsResponse]`), enforced admin role on topics routes, standardized `measure_system`, updated `conversation_config.max_turns`, and documented extraction model behavior/defaults. |
-| 2026-01-30 | 3.0 | **Issue #158 Completion:** Added tier-based LLM model selection and topic access control. Replaced `model_code` with `basic_model_code` and `premium_model_code`. Added `tier_level` field (FREE, BASIC, PREMIUM, ULTIMATE). |
-| 2026-01-25 | 2.0 | **Issue #196 Completion:** Fixed category enum values to match actual TopicCategory implementation, verified all field values match constants.py |
-| 2025-12-25 | 1.0 | Initial admin specification |
-
----
-
-## Overview
-
-This document specifies all admin endpoints for managing the LLM Topic system. Admin users can update topic configurations, manage prompts, and test topics.
-
-**Important:** Most topics are defined in the code-based `endpoint_registry`, but admin create/delete endpoints also exist in the API (currently not used by the Admin UI). In practice, admins mainly:
-- Update topic configurations (tier level, dual LLM models, temperature, prompts, etc.)
-- Manage prompt content (system, user, assistant prompts)
-- Test topic configurations before activation
-
-### Tier-Based Access Control (Issue #158)
-
-Each topic has a `tier_level` that controls:
-1. **Topic Access**: Which subscription tiers can access the topic
-2. **Model Selection**: Which LLM model to use based on user's tier
-
-**Tier Levels:**
-- **FREE**: Users can access only FREE topics, uses `basic_model_code`
-- **BASIC**: Users can access FREE + BASIC topics, uses `basic_model_code`
-- **PREMIUM**: Users can access FREE + BASIC + PREMIUM topics, uses `premium_model_code`
-- **ULTIMATE**: Users can access all topics, uses `premium_model_code`
-
-**Dual Model Configuration:**
-- `basic_model_code`: LLM model for FREE and BASIC tier users
-- `premium_model_code`: LLM model for PREMIUM and ULTIMATE tier users
-- Admins can set different models for each tier (e.g., Claude Haiku for basic, Claude Sonnet for premium)
-

-## Authentication
-
-All endpoints in this document require a bearer token:
-
-- **Authentication**: `Authorization: Bearer {token}` must be present and valid
-- **Authorization (current implementation)**:
-  - `/api/v1/admin/models*` endpoints enforce admin access (`ADMIN` or `OWNER`) via `require_admin_access`
-  - `/api/v1/admin/topics*` endpoints enforce admin access (`ADMIN` or `OWNER`) via `require_admin_access`
-- **Headers**:
-  - `Authorization: Bearer {token}`
-  - `Content-Type: application/json`

-
-**Response Schema (when `include_schema=true`):**
-
-When the `include_schema` query parameter is set to `true`, the response includes the JSON schema of the expected response model. This is useful for template authors to understand what output fields their prompts should generate.
-
-Example with `include_schema=true`:
-
-```json
-{
-  "topic_id": "niche_review",
-  "...": "...other fields...",
-  "response_schema": {
-    "title": "OnboardingReviewResponse",
-    "type": "object",
-    "properties": {
-      "strengths": {
-        "type": "array",
-        "items": {"type": "string"},
-        "description": "List of strengths identified"
-      },
-      "weaknesses": {
-        "type": "array",
-        "items": {"type": "string"},
-        "description": "List of weaknesses or areas for improvement"
-      },
-      "recommendations": {
-        "type": "array",
-        "items": {"type": "string"},
-        "description": "List of actionable recommendations"
-      },
-      "alignment_score": {
-        "type": "integer",
-        "minimum": 0,
-        "maximum": 100,
-        "description": "Overall alignment score"
-      },
-      "summary": {
-        "type": "string",
-        "description": "Summary of the analysis"
-      }
-    },
-    "required": ["strengths", "weaknesses", "recommendations", "alignment_score", "summary"]
-  }
-}
-```
-
-**Note:** The `response_schema` is `null` when:
-- `include_schema=false` (default)
-- The topic is not in the endpoint registry (custom topics)
-- The response model is not registered in the response model registry
-
-**Conversation Config (conversation_coaching topics only):**
-
-For topics with `topic_type: "conversation_coaching"`, the response includes `conversation_config`:
-
-| Field | Type | Range | Default | Description |
-|-------|------|-------|---------|-------------|
-| `max_messages_to_llm` | integer | 5-100 | 30 | Maximum messages to include in LLM context (sliding window) |
-| `inactivity_timeout_minutes` | integer | 5-1440 | 30 | Minutes of inactivity before session auto-pauses |
-| `session_ttl_days` | integer | 1-90 | 14 | Days to keep paused/completed sessions before deletion |
-| `max_turns` | integer | 0-100 | 0 | Maximum conversation turns (0 means unlimited) |
-| `extraction_model_code` | string | - | CLAUDE_3_5_HAIKU | MODEL_REGISTRY code for extraction (e.g., CLAUDE_3_5_HAIKU, CLAUDE_3_5_SONNET_V2) |
-
-**Compatibility Note:** Existing records may still contain `estimated_messages`. The API maps legacy `estimated_messages` to `max_turns` for backward compatibility.
-
-### Extraction Model Runtime Behavior
-
-For `conversation_coaching` completion/extraction:
-
-- API uses `conversation_config.extraction_model_code` when provided
-- Default extraction model is `CLAUDE_3_5_HAIKU`
-- If configured extraction model code is not present in `MODEL_REGISTRY`, runtime falls back to `CLAUDE_3_HAIKU`
-- Extraction call runs with `temperature=0.3`
-- Extraction max tokens are capped to `min(8192, extraction_model.max_tokens)`
-
-**Template Status:**
-
-The `template_status` array shows each allowed template and its definition status:
-
-| Field | Description |
-|-------|-------------|
-| `is_defined` | `true` if this prompt has been uploaded to S3 |
-| `s3_bucket`, `s3_key` | S3 location (null if not defined) |
-| `updated_at`, `updated_by` | Last update info (null if not defined) |
-
-**Status Codes:**
-
-- `200 OK`: Success
-- `404 Not Found`: Topic does not exist
-- `401 Unauthorized`: Missing or invalid auth token
-- `403 Forbidden`: Insufficient permissions
-
----
-
-### 3. Create Topic
-
-**Purpose:** Create a new topic with configuration
-
-**Endpoint:**
-
-```http
-POST /api/v1/admin/topics
-```
-
-**Request Body:**
-
-```json
-{
-  "topic_id": "purpose_discovery",
-  "topic_name": "Purpose Discovery Session",
-  "category": "purpose",
-  "topic_type": "conversation_coaching",
-  "description": "Discover your life's purpose through guided conversation",
-  "tier_level": "free",
-  "basic_model_code": "CLAUDE_3_5_HAIKU",
-  "premium_model_code": "CLAUDE_3_5_SONNET_V2",
-  "temperature": 0.7,
-  "max_tokens": 2000,

-  "frequency_penalty": 0.0,
-  "presence_penalty": 0.0,
-  "is_active": false,
-  "display_order": 10
-}
-```
-

-## Admin UI Workflows
-
-### Configuring a Topic
-
-Topics are defined in the `endpoint_registry` code. Admins configure them by:
-
-1. **GET** `/api/v1/admin/topics` - View all topics with `templates` (showing allowed and defined prompts)
-2. **GET** `/api/v1/admin/topics/{topic_id}` - Get topic details with `template_status` and `allowed_parameters`
-3. **POST** `/api/v1/admin/topics/{topic_id}/prompts` - Upload required prompts (system, user, etc.)
-4. **PUT** `/api/v1/admin/topics/{topic_id}` - Update model config (temperature, max_tokens, etc.)
-5. **POST** `/api/v1/admin/topics/{topic_id}/test` - Test with sample parameters
-6. **PUT** `/api/v1/admin/topics/{topic_id}` - Activate topic (`is_active: true`)
-
-### Editing Prompts
-
-1. **GET** `/api/v1/admin/topics/{topic_id}` - Get topic details with `template_status` and `allowed_parameters`
-2. **GET** `/api/v1/admin/topics/{topic_id}/prompts/{prompt_type}` - Get current content
-3. Edit in UI using `allowed_parameters` as available placeholders
-4. **PUT** `/api/v1/admin/topics/{topic_id}/prompts/{prompt_type}` - Save changes
-5. **POST** `/api/v1/admin/topics/{topic_id}/test` - Test the changes
-6. Cache cleared automatically

+# Admin AI Specifications - LLM Topic Management
+
+- Last Updated: February 13, 2026
+- Version: 3.1
+
+## Revision History
+
+| Date | Version | Description |
+|------|---------|-------------|
+| 2026-02-13 | 3.1 | Synced spec to implementation for admin model responses, topic auth, topic type terminology, and conversation extraction config. Updated `/models` response shape (`ApiResponse[LLMModelsResponse]`), enforced admin role on topics routes, standardized `measure_system`, updated `conversation_config.max_turns`, and documented extraction model behavior/defaults. |
+| 2026-01-30 | 3.0 | **Issue #158 Completion:** Added tier-based LLM model selection and topic access control. Replaced `model_code` with `basic_model_code` and `premium_model_code`. Added `tier_level` field (FREE, BASIC, PREMIUM, ULTIMATE). |
+| 2026-01-25 | 2.0 | **Issue #196 Completion:** Fixed category enum values to match actual TopicCategory implementation, verified all field values match constants.py |
+| 2025-12-25 | 1.0 | Initial admin specification |
+
+---
+
+## Overview
+
+This document specifies all admin endpoints for managing the LLM Topic system. Admin users can update topic configurations, manage prompts, and test topics.
+
+**Important:** Most topics are defined in the code-based `endpoint_registry`, but admin create/delete endpoints also exist in the API (currently not used by the Admin UI). In practice, admins mainly:
+- Update topic configurations (tier level, dual LLM models, temperature, prompts, etc.)
+- Manage prompt content (system, user, assistant prompts)
+- Test topic configurations before activation
+
+### Tier-Based Access Control (Issue #158)
+
+Each topic has a `tier_level` that controls:
+1. **Topic Access**: Which subscription tiers can access the topic
+2. **Model Selection**: Which LLM model to use based on user's tier

+```
+
+**Response Schema (when `include_schema=true`):**
+
+When the `include_schema` query parameter is set to `true`, the response includes the JSON schema of the expected response model. This is useful for template authors to understand what output fields their prompts should generate.
+
+Example with `include_schema=true`:
+
+```json
+{
+  "topic_id": "niche_review",
+  "...": "...other fields...",
+  "response_schema": {
+    "title": "OnboardingReviewResponse",
+    "type": "object",
+    "properties": {
+      "strengths": {
+        "type": "array",
+        "items": {"type": "string"},
+        "description": "List of strengths identified"
+      },
+      "weaknesses": {
+        "type": "array",
+        "items": {"type": "string"},
+        "description": "List of weaknesses or areas for improvement"
+      },
+      "recommendations": {
+        "type": "array",
+        "items": {"type": "string"},
+        "description": "List of actionable recommendations"
+      },
+      "alignment_score": {
+        "type": "integer",
+        "minimum": 0,
+        "maximum": 100,
+        "description": "Overall alignment score"
+      },
+      "summary": {
+        "type": "string",
+        "description": "Summary of the analysis"
+      }
+    },
+    "required": ["strengths", "weaknesses", "recommendations", "alignment_score", "summary"]
+  }
+}
+```
+
+**Note:** The `response_schema` is `null` when:
+- `include_schema=false` (default)
+- The topic is not in the endpoint registry (custom topics)
+- The response model is not registered in the response model registry
+
+**Conversation Config (conversation_coaching topics only):**
+
+For topics with `topic_type: "conversation_coaching"`, the response includes `conversation_config`:
+
+| Field | Type | Range | Default | Description |
+|-------|------|-------|---------|-------------|
+| `max_messages_to_llm` | integer | 5-100 | 30 | Maximum messages to include in LLM context (sliding window) |
+| `inactivity_timeout_minutes` | integer | 5-1440 | 30 | Minutes of inactivity before session auto-pauses |
+| `session_ttl_days` | integer | 1-90 | 14 | Days to keep paused/completed sessions before deletion |
+| `max_turns` | integer | 0-100 | 0 | Maximum conversation turns (0 means unlimited) |
+| `extraction_model_code` | string | - | CLAUDE_3_5_HAIKU | MODEL_REGISTRY code for extraction (e.g., CLAUDE_3_5_HAIKU, CLAUDE_3_5_SONNET_V2) |
+
+**Compatibility Note:** Existing records may still contain `estimated_messages`. The API maps legacy `estimated_messages` to `max_turns` for backward compatibility.
+
+### Extraction Model Runtime Behavior
+
+For `conversation_coaching` completion/extraction:
+
+- API uses `conversation_config.extraction_model_code` when provided
+- Default extraction model is `CLAUDE_3_5_HAIKU`
+- If configured extraction model code is not present in `MODEL_REGISTRY`, runtime falls back to `CLAUDE_3_HAIKU`
+- Extraction call runs with `temperature=0.3`
+- Extraction max tokens are capped to `min(8192, extraction_model.max_tokens)`
+
+**Template Status:**
+
+The `template_status` array shows each allowed template and its definition status:
+
+| Field | Description |
+|-------|-------------|
+| `is_defined` | `true` if this prompt has been uploaded to S3 |
+| `s3_bucket`, `s3_key` | S3 location (null if not defined) |
+| `updated_at`, `updated_by` | Last update info (null if not defined) |
+
+**Status Codes:**
+
+- `200 OK`: Success
+- `404 Not Found`: Topic does not exist
+- `401 Unauthorized`: Missing or invalid auth token
+- `403 Forbidden`: Insufficient permissions
+
+---
+
+### 3. Create Topic

+**Purpose:** Create a new topic with configuration
+
+**Endpoint:**
+
+```http

+
+## Admin UI Workflows
+
+### Configuring a Topic
+
+Topics are defined in the `endpoint_registry` code. Admins configure them by:
+
+1. **GET** `/api/v1/admin/topics` - View all topics with `templates` (showing allowed and defined prompts)
+2. **GET** `/api/v1/admin/topics/{topic_id}` - Get topic details with `template_status` and `allowed_parameters`
+3. **POST** `/api/v1/admin/topics/{topic_id}/prompts` - Upload required prompts (system, user, etc.)
+4. **PUT** `/api/v1/admin/topics/{topic_id}` - Update model config (temperature, max_tokens, etc.)
+5. **POST** `/api/v1/admin/topics/{topic_id}/test` - Test with sample parameters
+6. **PUT** `/api/v1/admin/topics/{topic_id}` - Activate topic (`is_active: true`)
+
+### Editing Prompts
+
+1. **GET** `/api/v1/admin/topics/{topic_id}` - Get topic details with `template_status` and `allowed_parameters`
+2. **GET** `/api/v1/admin/topics/{topic_id}/prompts/{prompt_type}` - Get current content
+3. Edit in UI using `allowed_parameters` as available placeholders
+4. **PUT** `/api/v1/admin/topics/{topic_id}/prompts/{prompt_type}` - Save changes
+5. **POST** `/api/v1/admin/topics/{topic_id}/test` - Test the changes
+6. Cache cleared automatically
+
+---
+
+## Error Codes
+
+Error payloads are returned as FastAPI `HTTPException` details and are endpoint-specific.
+Use per-endpoint status code tables above as the source of truth.
+
+---
+
+## Rate Limiting
+
+Admin endpoints have separate rate limits:
+
+- **Read operations**: 100 requests/minute
+- **Write operations**: 20 requests/minute
+- **Bulk operations**: 5 requests/minute
+
+Headers:
+
+```
+X-RateLimit-Limit: 100
+X-RateLimit-Remaining: 95
+X-RateLimit-Reset: 1699987200
+```
+
+---
+
+## Permissions
+
+Current backend enforcement:
+
+- `GET/PUT /api/v1/admin/models*`: requires admin role (`ADMIN` or `OWNER`) via `require_admin_access`
+- `/api/v1/admin/topics*`: requires admin role (`ADMIN` or `OWNER`) via `require_admin_access`
+
+---
+
+## Versioning
+
+API Version: `v1`

-# Coaching Session Workflow Guide
-
-**Version:** 3.0  
-**Last Updated:** February 12, 2026  
-**Status:** Active
-
-[← Back to Backend Integration](./backend-integration-unified-ai.md)
-
----
-
-## Purpose
-
-This guide explains the coaching journey in human terms: how a session starts, pauses, resumes, and completes from a user experience perspective.
-
-**Technical API and payload contracts live in one place only:**
-- `docs/shared/Specifications/ai-user/backend-integration-unified-ai.md`
-- `docs/shared/Specifications/eventbridge/async-coaching-message-events.md`
-
----
-
-## Session Lifecycle
-
-Coaching sessions move through these states:
-
-- **ACTIVE**: User can continue messaging
-- **PAUSED**: User paused or frontend treats an idle session as paused on reopen
-- **COMPLETED**: Conversation is done and results are available
-- **CANCELLED**: User cancelled the session
-- **ABANDONED**: Older session replaced by a fresh start
-
-The main lifecycle principle:
-- **Start means new conversation**
-- **Resume means continue existing conversation**
-
----
-
-## User Journey
-
-### 1) User opens coaching
-
-The frontend checks if there is an existing session and whether there is a conflict with another user in the tenant.
-
-- If no session exists, user starts fresh.
-- If a resumable session exists, user chooses to resume or start new.
-- If there is a conflict, the UI blocks entry and shows guidance.
-
-### 2) User sends a message
-
-Message handling is asynchronous:
-
-- The API immediately accepts the request and returns a job identifier.
-- The backend processes the message in the background.
-- Frontend receives the result by WebSocket, or polling fallback.
-
-This avoids request timeouts on long model responses and keeps the UI responsive.
-
-### 3) Conversation continues or ends
-
-Each completed message indicates whether the conversation is final:
-
-- If not final, the user keeps chatting.
-- If final, the UI presents extracted results and closes or transitions the session.
-
-### 4) User pauses, resumes, or starts over
-
-- **Pause** explicitly blocks additional messages until resume.
-- **Resume** re-enters the existing session context.
-- **Start new** creates a fresh session and retires the old one.
-
----
-
-## Idle and Pause Behavior
-
-Idle time is treated as a UX signal, not a hard failure for active work:
-
-- A user who still has an active context can continue conversation flow.
-- On re-entry, frontend can present the session as paused and offer resume/new options.
-
----
-
-## Operational Notes
-
-- Sessions have TTL-based cleanup.
-- Async jobs are temporary and used for status tracking and delivery.
-- Frontend should treat job completion events idempotently.
-
----
-
-## Quick Checklist
-
-- Frontend checks session status before opening coaching UI
-- Frontend handles resume vs start-new explicitly
-- Message send uses async job flow
-- Completion handling uses finality flag + result payload
-- Pause/resume actions are reflected in UI state

+## 7) Cross-Event Compatibility Rules
+
+1. `definition.version` and `definition.hash` in terminal events must match the requested event.
+2. `runtimeBindingsExpected` (if provided) must be a subset of terminal `parameterBindingsSchema` keys.
+3. `sqlPolicy.bindPlaceholderStyle` must match placeholders used in emitted `sqlTemplate`.
+4. `appliedParameters` + `ignoredParameters[].name` should represent all provided parameter values considered by the generator.
+
+---
+
+## 8) Behavioral Guarantees
+
+1. **Idempotency:** at most one terminal event per `generationId`.
+2. **Terminal guarantee:** exactly one of completed/failed for a given `generationId`.
+3. **Security:** no credentials or secrets in events/logs.
+4. **Validation gate:** completed event requires `validated = true`.
+5. **Parameterization:** SQL template must not interpolate user values.
+6. **Policy semantics:** `maxRows` refers to **final result set rows**, not scanned source rows.

+
+## 11) Deprecated Event Mapping (Migration Note)
+
+The following event names are deprecated and must not be used for new integrations:

+
+Additional note:
+- `integration.measure.read.skipped` has no direct V1.2 equivalent in this SQL-template generation contract and remains out of scope unless explicitly reintroduced in a future contract version.

+**Base Path:** `/admin/api/v1/integrations`  
+**Version:** 1.1  
+**Last Updated:** February 19, 2026
+
+## Overview
+
+This specification defines admin-only integration endpoints for metadata synchronization and integration-definition management.

+### Key Capabilities
+
+- Synchronize available systems from CData
+- Define catalog measure intent for SQL-template generation

+
+### Out of Scope
+
+- User-facing connection/integration/test endpoints
+- Runtime execution endpoints
+
+---

+## Changelog
+
+| Version | Date | Changes |
+|---------|------|----------|
+| 2.0 | December 26, 2025 | **BREAKING:** Converted all JSON properties from snake_case to camelCase to match C#/.NET implementation (e.g., `person_id` → `personId`, `first_name` → `firstName`). Query parameters also converted to camelCase. This matches ASP.NET Core default JSON serialization. |
+| 1.1 | December 23, 2025 | Migrated People endpoints from Traction service to Account service |
+| 1.0 | December 21, 2025 | Initial version |
+
+---
+
+## Overview
+
+The People module manages all person records within a tenant, including employees, consultants, vendors, and other stakeholders. This module also handles Person Types, Tags, and the User-Person linking that enables work item assignments.
+
+### Frontend Implementation
+
+- **Primary Client:** `accountClient` (axios instance) ⚠️ *Changed from tractionClient*
+- **Related Files:**
+  - `src/services/people-service.ts` - Person CRUD operations
+  - `src/services/person-types-service.ts` - Person type management
+  - `src/services/person-tags-service.ts` - Tag management
+
+### Key Concepts
+
+- **Person**: Any individual related to the business (may or may not have system access)
+- **User**: A Person with PurposePath login credentials
+- **PersonType**: Category defining relationship to business (Employee, Vendor, etc.)
+- **Tag**: Flexible label for grouping/filtering people
+- **Assignable**: Flag indicating if a person can receive work assignments
+
+### Email Verification
+
+A Person's `isEmailVerified` flag is set to `true` when:
+1. They accept a user invitation and create their account (primary flow)
+2. They complete email verification during password reset
+
+There is no explicit `POST /people/{id}/verify-email` endpoint. Email verification is implicitly handled through the user invitation acceptance flow.
+
+---
+
+## Authentication Changes
+
+### POST /auth/login
+
+User authentication with username/password.
+
+**⚠️ BREAKING CHANGE:** Login now uses `username` instead of `email`.
+
+**Request:**
+
+```json
+{
+  "username": "string",
+  "password": "string"
+}
+```
+
+**Field Constraints:**
+
+| Field | Type | Required | Constraints |
+|-------|------|----------|-------------|
+| username | string | Yes | 3-50 characters |
+| password | string | Yes | Min 8 characters |
+
+**Response:**
+
+```json
+{
+  "success": true,
+  "data": {

+      "avatarUrl": "string?",
+      "createdAt": "string (ISO 8601)",
+      "updatedAt": "string (ISO 8601)",
+      "status": "active | inactive | locked",
+      "preferences": {}
+    },
+    "person": {
+      "id": "string (GUID)",

+    "tenant": {
+      "id": "string (GUID)",
+      "name": "string"
+    }
+  }
+}
+```
+
+**Error Responses:**
+
+```json
+{
+  "success": false,
+  "error": "Invalid username or password",
+  "code": "INVALID_CREDENTIALS"
+}
+```
+
+```json
+{
+  "success": false,
+  "error": "Account is locked",
+  "code": "ACCOUNT_LOCKED",
+  "details": {
+    "lockedUntil": "2025-12-22T10:30:00Z"
+  }
+}
+```
+
+**Frontend Handling:**
+
+- Stores `accessToken` → `localStorage.accessToken`
+- Stores `refreshToken` → `localStorage.refreshToken`
+- Stores `tenant.id` → `localStorage.tenantId`
+- Person data available for profile display
+
+---
+
+### POST /auth/forgot-username

+
+```json
+{
+  "success": true,
+  "message": "If the email is associated with any accounts, instructions have been sent."
+}
+```
+
+**Backend Behavior:**
+
+1. Find all Persons with verified email matching input

+# Integration Service API Specification (User App)
+
+**Service:** Integration Service  
+**Base Path:** `/integration`  
+**Version:** 1.1  
+**Last Updated:** February 19, 2026
+
+## Overview
+
+The Integration Service API enables end-user integration workflows in Settings and Measure screens.  
+This specification covers **user-facing** endpoints only (no admin metadata-definition endpoints).
+
+### Contract Source of Truth
+
+- Backend async Integration AI+CData event contracts are specified in [../integration/async-integration-ai-cdata-contracts.md](../../integration/async-integration-ai-cdata-contracts.md).
+- This frontend spec owns UX-facing request/response behavior and client handling expectations.
+- Backend event schema changes must be reflected in both docs in the same change set.
+
+### Key Capabilities
+
+- Connected systems list with status/diagnostics and measure counts
+- Add-system bootstrap (provider subaccount + connection persistence)
+- Measure integration create/edit/delete with eligibility checks
+- Snapshot/aggregate scheduling controls and frequency rules
+- Parameter selection with optional lookup values (`valueKey` + `valueName`)
+- Test-first lifecycle and save gating based on tested-state validity
+
+---
+
+## Authentication & Headers
+
+```http
+Authorization: Bearer {accessToken}
+X-Tenant-Id: {tenantId}
+Content-Type: application/json
+```
+
+All endpoints are tenant-scoped and require authenticated user context.
+
+---
+
+## Endpoint Summary
+
+| Method | Endpoint | Description |
+|---|---|---|
+| GET | `/connections` | List connected systems with aggregate integration data |
+| GET | `/connections/eligible-systems` | Systems user can add now based on eligible measures |
+| POST | `/connections/bootstrap` | Ensure tenant-provider/subaccount bootstrap exists |
+| POST | `/connections` | Persist system connection returned by provider flow |
+| PATCH | `/connections/{connectionId}` | Edit connection display/settings details |
+| POST | `/connections/{connectionId}/test` | Test connection and refresh health status |
+| GET | `/connections/{connectionId}/measures` | List integrations under a connection |
+| GET | `/measure-integrations/eligible-measures` | List measures eligible for integration for selected system |
+| GET | `/measure-integrations/{integrationId}` | Get integration details for edit/view |
+| POST | `/measure-integrations` | Create integration (save-gated by tested state) |
+| PUT | `/measure-integrations/{integrationId}` | Update integration (save-gated by tested state rules) |
+| DELETE | `/measure-integrations/{integrationId}` | Delete integration |
+| POST | `/measure-integrations/{integrationId}/test` | Test retrieval only (no measure-data persistence) |

+
+Returns `MeasureIntegrationResponse`.
+
+---
+
+### 9) Update Measure Integration
+
+**PUT** `/measure-integrations/{integrationId}`
+
+Same payload model as create.
+
+`testFingerprint` is optional for update and is only required when template-affecting changes are included.
+
+#### Save-Gating Rules
+
+- Template-affecting changes require valid tested state before save:
+  - parameter enable/disable
+  - parameter value changes
+  - calculation method changes
+  - timezone changes
+  - period/lag semantics changes
+- Frequency-only changes do not invalidate tested state.
+- If template-affecting changes are submitted without a fresh `testFingerprint`, save fails with code `RETEST_REQUIRED_FOR_TEMPLATE_CHANGES`.
+
+---
+
+### 10) Test Measure Integration
+
+**POST** `/measure-integrations/{integrationId}/test`
+
+Runs retrieval path and returns computed value + execution metadata.  
+Does **not** persist measure actuals/current measure value.
+
+#### Response (200)
+
+```json
+{
+  "success": true,
+  "data": {
+    "integrationId": "f8f8d8b7-81de-42f7-b689-c0d4b709bc3d",

+## Purpose
+
+This document is the backend contract source of truth for asynchronous Integration orchestration between:
+
+- Integration Service (backend)
+- AI template generation service
+- CData execution path
+
+It defines event schemas, lifecycle transitions, retryability semantics, idempotency, and tenant/security constraints.
+
+## Cross-References
+
+- Frontend/user-facing Integration service behavior: [../api-fe/traction-service/integration-service.md](../api-fe/traction-service/integration-service.md)
+- Legacy coaching async frontend spec: [async-coaching-message-events.md](async-coaching-message-events.md)

+- `Pending`
+- `Requested`
+- `Completed`
+- `Failed`
+
+Rules:
+
+1. Exactly one terminal outcome per `(measureIntegrationId, generationId)` identity.
+2. Duplicate terminal event with same terminal state is idempotent and ignored.
+3. Conflicting terminal event for same generation id (e.g., completed then failed) is rejected.
+4. Tenant mismatch between event and aggregate is rejected.
+
+### Execution Lifecycle
+
+Execution outcomes are processed idempotently by `executionId` and `dataSource`:
+
+1. Duplicate execution results are ignored.
+2. Retryable failures schedule retry.
+3. Non-retryable failures block auto-execution.
+4. Circuit-breaker opens after repeated retryable failures and blocks auto-execution.
+
+---
+
+## Retryability Semantics
+
+### Template Generation Failed Contract
+
+For `SqlTemplateGenerationFailedDetail`:
+
+- `retryable=true` requires `retryAfterSeconds > 0`
+- `retryable=false` requires `retryAfterSeconds = null`
+- `errorCode` and `errorStage` must be from canonical constant sets
+
+### Execution Result Contract
+
+`retryable` and `failureClass` must agree semantically:
+
+- `RETRYABLE` -> `retryable=true`
+- `NON_RETRYABLE` -> `retryable=false`
+- `CIRCUIT_BREAKER` -> terminal block/no auto-retry
+
+---
+
+## Deterministic Error Taxonomy
+
+### Template Generation
+
+Canonical values are defined in `SqlTemplateGenerationContractConstants`:
+
+- Error codes: `SQL_POLICY_VIOLATION`, `SQL_VALIDATION_FAILED`, `SCHEMA_DISCOVERY_FAILED`, `MCP_TOOL_ERROR`, `AI_OUTPUT_INVALID`, `CDATA_AUTH_INVALID`, `CDATA_CONNECTION_NOT_FOUND`, `CDATA_RATE_LIMITED`, `INTERNAL_UNHANDLED`
+- Error stages: `DISCOVER`, `GENERATE`, `VALIDATE`, `REPAIR`, `PUBLISH`
+
+### Execution Processing
+
+Deterministic execution error codes include:
+
+- `EXECUTION_ARGUMENT_INVALID`
+- `EXECUTION_CONTRACT_INVALID`
+- `EXECUTION_RESOURCE_NOT_FOUND`
+- `EXECUTION_INVALID_OPERATION`
+- `EXECUTION_TRANSIENT`
+- `EXECUTION_FAILED`
+- `CDATA_AUTH_INVALID`
+
+---
+
+## Security and Tenant Isolation
+
+1. Tenant identity is validated before applying terminal events.
+2. Credentials must not be published in events.
+3. Logs and emitted failure messages must be sanitized for sensitive tokens/secrets.
+4. Connection/auth failures are represented by deterministic error codes, not raw secret payloads.
+
+---
+
+## Implementation Verification Checklist
+
+- [x] Event schemas implementation-verified in code and tests
+- [x] Terminal dedupe and conflicting terminal behavior covered in unit tests
+- [x] Retryable/non-retryable semantics validated for failed template events
+- [x] Execution failure class represented explicitly in queue contract
+- [x] API parity fields for lifecycle/error observability exposed in active integration response
+- [x] Cross-reference added to frontend integration-service specification
+
+---
+
+## Notes
+
+- This file intentionally excludes frontend coaching-specific guidance.
+- Frontend/client behavior belongs in [../api-fe/traction-service/integration-service.md](../api-fe/traction-service/integration-service.md).

-# People & Organizational Structure - Backend Integration Specifications (Part 1: People)
-
-**Version:** 2.0  
-**Last Updated:** December 26, 2025  
-**Service Base URL:** `{REACT_APP_ACCOUNT_API_URL}` (People & Auth endpoints)  
-**Default (Localhost):** `http://localhost:8001` (Account)

-## Changelog
-
-| Version | Date | Changes |
-|---------|------|----------|
-| 2.0 | December 26, 2025 | **BREAKING:** Converted all JSON properties from snake_case to camelCase to match C#/.NET implementation (e.g., `person_id` → `personId`, `first_name` → `firstName`). Query parameters also converted to camelCase. This matches ASP.NET Core default JSON serialization. |
-| 1.1 | December 23, 2025 | Migrated People endpoints from Traction service to Account service |
-| 1.0 | December 21, 2025 | Initial version |
-
----
-
-## Overview
-
-The People module manages all person records within a tenant, including employees, consultants, vendors, and other stakeholders. This module also handles Person Types, Tags, and the User-Person linking that enables work item assignments.
-
-### Frontend Implementation
-
-- **Primary Client:** `accountClient` (axios instance) ⚠️ *Changed from tractionClient*
-- **Related Files:**
-  - `src/services/people-service.ts` - Person CRUD operations
-  - `src/services/person-types-service.ts` - Person type management
-  - `src/services/person-tags-service.ts` - Tag management
-
-### Key Concepts
-
-- **Person**: Any individual related to the business (may or may not have system access)
-- **User**: A Person with PurposePath login credentials
-- **PersonType**: Category defining relationship to business (Employee, Vendor, etc.)
-- **Tag**: Flexible label for grouping/filtering people
-- **Assignable**: Flag indicating if a person can receive work assignments
-
-### Email Verification
-
-A Person's `isEmailVerified` flag is set to `true` when:
-1. They accept a user invitation and create their account (primary flow)
-2. They complete email verification during password reset
-
-There is no explicit `POST /people/{id}/verify-email` endpoint. Email verification is implicitly handled through the user invitation acceptance flow.
-
----
-
-## Authentication Changes
-
-### POST /auth/login
-
-User authentication with username/password.
-
-**⚠️ BREAKING CHANGE:** Login now uses `username` instead of `email`.
-
-**Request:**
-
-```json
-{
-  "username": "string",
-  "password": "string"
-}
-```
-
-**Field Constraints:**
-
-| Field | Type | Required | Constraints |
-|-------|------|----------|-------------|
-| username | string | Yes | 3-50 characters |

+
+## Overview
+
+The Admin API provides comprehensive administrative capabilities for managing the PurposePath platform. It includes functionality for:
+
+- **System Configuration**: Seeding reference data (tiers, settings, templates)
+- **System Settings**: Managing operational parameters, security policies, email/payment configuration
+- **Role Templates**: Managing organizational structure templates for tenants
+- **Subscription Management**: Managing plans, pricing, subscribers, features, discount codes
+- **Email Templates**: Creating and managing email templates
+- **Issue Configuration**: Configuring issue types and statuses
+- **User Support**: Trial extensions, discounts, feature grants
+- **User Management**: Account operations (unlock, suspend, reactivate)
+- **Audit Logging**: Comprehensive tracking and reporting of all administrative actions
+
+**Security**: All endpoints require Admin role authorization via JWT token with "Admin" policy claim.
+
+**Audit Trail**: All write operations are automatically logged with admin user ID, action details, and timestamps.
+
+---
+
+## Authentication
+
+### Required Headers
+
+All Admin API endpoints (except auth endpoints) require:
+
+```http
+Authorization: Bearer {admin_access_token}
+Content-Type: application/json
+```
+
+### Admin Role Requirement
+
+Admins must be members of the **Portal Admins** Google Workspace group. The validation process:
+
+1. Admin authenticates via Google OAuth 2.0
+2. System validates Google Workspace group membership
+3. JWT token is issued with "Admin" role claim
+4. All subsequent requests validated against this role
+
+### Token Expiration
+
+- **Access Token**: 1 hour
+- **Refresh Token**: 30 days
+- Use `POST /auth/refresh` to obtain new tokens
+
+---
+
+## Common Patterns
+
+### Pagination
+
+Paginated endpoints use consistent query parameters:
+
+```
+?page=1&pageSize=20
+```
+
+**Response Structure:**
+```json
+{
+  "success": true,
+  "data": {
+    "items": [...],
+    "pagination": {
+      "currentPage": 1,
+      "pageSize": 20,
+      "totalCount": 150,
+      "totalPages": 8
+    }
+  }
+}
+```
+
+**Constraints:**
+- `page`: Minimum 1 (1-based indexing)
+- `pageSize`: 1-100 (default: 20-50 depending on endpoint)
+
+### Response Envelope
+
+**Success Response:**
+```json
+{
+  "success": true,
+  "data": { ... }
+}
+```
+
+**Error Response:**
+```json
+{
+  "success": false,
+  "error": "Human-readable error message"
+}
+```
+
+### Seeding Results
+
+System seeding endpoints return:
+
+```json
+{
+  "itemsCreated": 10,
+  "itemsSkipped": 5,
+  "errors": ["Optional error message"]
+}
+```
+
+**Pattern**: INSERT-IF-NOT-FOUND (idempotent operations)
+
+### Audit Logging
+
+All write operations automatically log:
+- Admin user ID
+- Action type (create, update, delete, etc.)
+- Resource type and ID
+- Descriptive message
+- Timestamp
+- IP address (from request context)
+
+---
+
+## Endpoints by Category

+---
+
+## Health & System
+
+### GET /health
+
+Health check endpoint (no authentication required).

+  "timestamp": "2026-02-04T10:30:00Z",
+  "environment": "Production"
+}
+```
+
+**Status Codes:**
+- `200 OK` - Service is healthy
+
+---
+
+## Authentication Endpoints
+
+### POST /auth/validate

+}
+```
+
+**Validations:**
+- `googleAccessToken`: Required, valid Google OAuth access token
+- `email`: Required, valid email format
+
+**Response:**
+```json
+{
+  "success": true,
+  "data": {
+    "id": "550e8400-e29b-41d4-a716-446655440000",

+{
+  "success": true,
+  "accessToken": "eyJ...",
+  "refreshToken": "eyJ...",
+  "expiresIn": 3600
+}
+```
+
+**Status Codes:**
+- `200 OK` - Token refreshed successfully
+- `400 Bad Request` - Missing refresh token
+- `401 Unauthorized` - Invalid or expired refresh token
+- `500 Internal Server Error` - Server error
+
+**Notes:**

+# Admin AI Specifications - LLM Topic Management
+
+- Last Updated: January 30, 2026
+- Version: 3.0
+
+## Revision History
+
+| Date | Version | Description |
+|------|---------|-------------|
+| 2026-01-30 | 3.0 | **Issue #158 Completion:** Added tier-based LLM model selection and topic access control. Replaced `model_code` with `basic_model_code` and `premium_model_code`. Added `tier_level` field (FREE, BASIC, PREMIUM, ULTIMATE). |
+| 2026-01-25 | 2.0 | **Issue #196 Completion:** Fixed category enum values to match actual TopicCategory implementation, verified all field values match constants.py |
+| 2025-12-25 | 1.0 | Initial admin specification |
+
+---
+
+## Overview
+
+This document specifies all admin endpoints for managing the LLM Topic system. Admin users can update topic configurations, manage prompts, and test topics.
+
+**Important:** Topics are defined in the code-based `endpoint_registry` and cannot be created or deleted by admins. Admins can only:
+- Update topic configurations (tier level, dual LLM models, temperature, prompts, etc.)
+- Manage prompt content (system, user, assistant prompts)
+- Test topic configurations before activation
+
+### Tier-Based Access Control (Issue #158)
+
+Each topic has a `tier_level` that controls:
+1. **Topic Access**: Which subscription tiers can access the topic
+2. **Model Selection**: Which LLM model to use based on user's tier
+
+**Tier Levels:**
+- **FREE**: Users can access only FREE topics, uses `basic_model_code`
+- **BASIC**: Users can access FREE + BASIC topics, uses `basic_model_code`
+- **PREMIUM**: Users can access FREE + BASIC + PREMIUM topics, uses `premium_model_code`
+- **ULTIMATE**: Users can access all topics, uses `premium_model_code`
+
+**Dual Model Configuration:**
+- `basic_model_code`: LLM model for FREE and BASIC tier users
+- `premium_model_code`: LLM model for PREMIUM and ULTIMATE tier users
+- Admins can set different models for each tier (e.g., Claude Haiku for basic, Claude Sonnet for premium)

+
+Example with `include_schema=true`:
+
+```json
+{
+  "topic_id": "niche_review",
+  "...": "...other fields...",
+  "response_schema": {
+    "title": "OnboardingReviewResponse",
+    "type": "object",

+      "weaknesses": {
+        "type": "array",
+        "items": {"type": "string"},

+
+## Overview
+
+The Unified AI system is **topic-centric**, not endpoint-centric. All AI capabilities are organized as **topics** identified by a `topic_id`. Topics are routed to the appropriate endpoint based on their type:
+
+- **Single-Shot Topics** → `/ai/execute` or `/ai/execute-async`
+- **Conversation Topics** → `/ai/coaching/*` endpoints
+
+Instead of separate endpoints for each capability, callers specify a `topic_id` and the appropriate parameters. The system handles routing, validation, and execution automatically.
+
+### Benefits
+
+- **Topic-driven architecture** - All capabilities defined as topics, not hardcoded endpoints
+- **Single endpoint** for all single-shot AI operations (`/ai/execute`)
+- **Dynamic response models** based on topic
+- **Schema discovery** via `/ai/schemas/{schema_name}`
+- **Topic listing** via `/ai/topics`
+- **Consistent error handling** across all topics
+- **Automatic parameter enrichment** from backend data sources
+- **Flexible routing** - Endpoints determine routing based on `TopicType`
+
+### Frontend Implementation
+
+- **Primary Client:** `coachingClient` (axios instance in `src/services/api.ts`)
+- **Key Pattern:** Call `/ai/execute` with `topic_id` and `parameters`
+- **Topic Discovery:** Use `GET /ai/topics` to discover available topics and their parameters
+
+---
+
+## Architecture
+
+### Topic-Centric Design
+
+The AI system is built around **topics**, not endpoints. Each topic represents a specific AI capability (e.g., `niche_review`, `alignment_check`, `core_values`). Topics are identified by a `topic_id` and are routed to the appropriate endpoint based on their `TopicType`:
+
+- **Single-Shot Topics** (`TopicType.SINGLE_SHOT`) → Use `/ai/execute` or `/ai/execute-async`
+- **Conversation Topics** (`TopicType.CONVERSATION_COACHING`) → Use `/ai/coaching/*` endpoints
+
+**Key Principle:** Endpoints determine routing based on `TopicType`. Topic definitions do not include endpoint paths or HTTP methods—these are determined by the endpoint handlers.
+
+### Topic Data Sources
+
+Topic information comes from multiple sources, each serving a specific purpose:
+
+| Source | Purpose | Contains |
+|--------|---------|----------|
+| **Topic Registry** (Static Code) | Topic metadata and validation | `topic_id`, `topic_type`, `category`, `description`, `response_model`, `parameter_refs`, `is_active` |
+| **DynamoDB** (via `TopicRepository`) | Runtime topic configuration | `model_code`, `temperature`, `max_tokens`, execution parameters, runtime settings |
+| **S3** (via `S3PromptStorage`) | Template content | System prompts, user prompts, template files referenced by topic |
+| **Topic Seed Data** | Initialization | Default configurations used to seed/initialize topics in DynamoDB |
+
+**Execution Flow:**
+1. Request arrives with `topic_id` → Topic Registry validates topic exists and is active
+2. DynamoDB provides runtime configuration (model, temperature, etc.)
+3. S3 provides prompt templates
+4. Parameter enrichment fetches data from various sources
+5. LLM executes with configured model and prompts
+6. Response is serialized to the topic's response model
+
+### Parameter Enrichment System
+
+The AI backend automatically enriches prompts with data from multiple sources. When you call `/ai/execute`, the system:
+
+1. **Identifies required parameters** from the topic registry
+2. **Groups parameters by source** (one API call per source)
+3. **Fetches data** from Business API, Account Service, etc.
+4. **Extracts individual values** using defined extraction paths
+5. **Renders prompts** with all gathered parameters
+
+This means frontend only needs to provide **request-level parameters** (e.g., `goal_id`, `measure_id`). Context like business foundation, strategies, and measures is automatically fetched.
+
+### Parameter Sources
+

+## Core Endpoints
+
+**Note:** All endpoints use topic-based routing. Topics are identified by `topic_id` and routed based on their `TopicType`:
+- `TopicType.SINGLE_SHOT` → `/ai/execute` or `/ai/execute-async`
+- `TopicType.CONVERSATION_COACHING` → `/ai/coaching/*` endpoints
+
+Topic definitions do not include endpoint paths or HTTP methods—these are determined by the endpoint handlers based on the topic's type.
+
+---
+
+### Standard Response Envelope
+
+**CRITICAL:** All API responses (coaching, single-shot, admin, health, etc.) are wrapped in a standard envelope structure. This is consistent across **ALL endpoints**.
+
+**Success Response Structure:**
+
+```json
+{
+  "success": true,
+  "data": {
+    // Endpoint-specific response data (varies by endpoint)
+  },
+  "message": "Operation completed successfully",  // Optional success message
+  "error": null,
+  "error_code": null,
+  "request_id": "550e8400-e29b-41d4-a716-446655440000",  // UUID for request tracing
+  "timestamp": "2026-02-08T21:45:23.123456Z"  // ISO 8601 timestamp with microseconds
+}
+```
+
+**Error Response Structure:**
+
+```json
+{
+  "success": false,
+  "data": null,
+  "message": null,
+  "error": "Detailed error message here",
+  "error_code": "ERROR_CODE_HERE",  // Optional structured error code
+  "request_id": "550e8400-e29b-41d4-a716-446655440000",
+  "timestamp": "2026-02-08T21:45:23.123456Z"
+}
+```
+
+**Envelope Fields:**
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `success` | boolean | Yes | `true` for successful responses, `false` for errors |
+| `data` | object \| null | Yes | Response payload (endpoint-specific), `null` on error |
+| `message` | string \| null | No | Optional success or info message |
+| `error` | string \| null | No | Error message (only present when `success: false`) |
+| `error_code` | string \| null | No | Structured error code for programmatic error handling |
+| `request_id` | string | Yes | Unique UUID for request tracing and debugging |
+| `timestamp` | string | Yes | ISO 8601 timestamp with microseconds (UTC) |
+
+**Important Notes:**
+- **All endpoints** use this envelope - there are no exceptions
+- Frontend should always check the `success` field first
+- Use `request_id` for debugging and error reporting
+- The `data` field structure varies by endpoint (documented in each endpoint section below)
+- When `success: false`, `data` is always `null` and `error` contains the error message
+
+---
+
+### POST /ai/execute

+
+#### ai.job.failed
+
+```json
+{
+  "jobId": "550e8400-e29b-41d4-a716-446655440000",
+  "tenantId": "tenant-123",

+
+### When to Use Async vs Sync
+
+| Use Case | Endpoint | Reason |
+|----------|----------|--------|
+| Quick operations (<10s) | `POST /ai/execute` | Simpler, immediate response |
+| Complex analysis (>20s) | `POST /ai/execute-async` | Avoids API Gateway timeout |
+| Batch operations | `POST /ai/execute-async` | Process in background |
+| User waiting on screen | `POST /ai/execute-async` | Better UX with progress |
+
+**Recommended:** Use async for onboarding review topics (`niche_review`, `ica_review`, `value_proposition_review`) as they may take 30-60 seconds depending on LLM load.
+
+---
+
+### Coaching Conversation Endpoints
+
+The Coaching Conversation endpoints provide multi-turn conversational coaching interactions. Unlike single-shot `/ai/execute` endpoints, coaching sessions maintain state across multiple messages.
+
+**Routing:** These endpoints handle all topics with `TopicType.CONVERSATION_COACHING`.
+
+**Base URL:** All coaching conversation endpoints are prefixed with `/ai/coaching`.
+
+**Full URL Pattern:** `{BASE_URL}/ai/coaching/{endpoint}`
+
+#### Available Coaching Topics
+
+| topic_id | Name | Description |
+|----------|------|-------------|
+| `core_values` | Core Values Discovery | Discover and articulate your organization's authentic core values |
+| `purpose` | Purpose Discovery | Define your organization's deeper purpose and reason for existing |
+| `vision` | Vision Crafting | Craft a compelling vision for your organization's future |
+
+**Important:** When calling `/ai/coaching/start`, use the `topic_id` value (e.g., `"core_values"`, `"purpose"`, `"vision"`) - NOT the registry key format.
+
+#### GET /ai/coaching/topics
+
+Get all coaching topics with user's completion status.
+
+**Full URL:** `{BASE_URL}/ai/coaching/topics`
+
+**Response:**
+
+```json
+{
+  "success": true,
+  "data": {
+    "topics": [
+      {
+        "topic_id": "core_values",
+        "name": "Core Values Discovery",
+        "description": "Discover and articulate your organization's authentic core values",
+        "status": "not_started",
+        "session_id": null,
+        "completed_at": null
+      }
+    ]
+  },
+  "message": "Topics retrieved successfully"
+}
+```
+
+#### GET /ai/coaching/session/check
+
+**NEW in v2.6** - Check if a resumable session exists for a topic.
+
+**Full URL:** `{BASE_URL}/ai/coaching/session/check?topic_id={topic_id}`
+
+**Request Parameters:**
+
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `topic_id` | string | Yes | ID of the coaching topic to check |
+
+**Response:**
+
+```json
+{
+  "success": true,
+  "data": {
+    "has_session": true,
+    "session_id": "sess_abc123",
+    "status": "paused",
+    "actual_status": "active",
+    "is_idle": true,
+    "conflict": false,
+    "conflict_user_id": null
+  }
+}
+```
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `has_session` | boolean | Whether current user has an active/paused session for this topic |
+| `session_id` | string \| null | Session ID if exists |
+| `status` | string \| null | Computed status: "active" or "paused" (see below) |
+| `actual_status` | string \| null | Raw database status |
+| `is_idle` | boolean | Whether session has been idle > 30 minutes |
+| `conflict` | boolean | Whether another user from same tenant has active session |
+| `conflict_user_id` | string \| null | Other user's ID if conflict |
+
+**Status Logic:**
+- Returns `"paused"` if session is explicitly PAUSED **OR** ACTIVE but idle > 30 minutes
+- Returns `"active"` if session is ACTIVE and NOT idle
+
+**Use Case:** Frontend calls this before starting/resuming to show appropriate UI:
+- If `status === "paused"` → Show "Resume or Start New?" dialog
+- If `conflict === true` → Show "Another user is using this topic"
+- If `has_session === false` → Show "Start Session"
+
+---
+
+#### POST /ai/coaching/start
+
+**CHANGED in v2.6** - Now ALWAYS creates a new session (cancels any existing session).

+    "category": "strategy",  // Optional filter
+    "priority": "high",      // Optional filter
+    "status": "active"       // Optional filter
+  }
+}
+```
+
+**Request Parameters:**
+
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `page` | number | No | Page number for pagination (default: 1) |
+| `page_size` | number | No | Items per page (default: 20, max: 100) |
+| `category` | string | No | Filter by category: strategy, operations, finance, marketing, leadership, technology |
+| `priority` | string | No | Filter by priority: critical, high, medium, low |
+| `status` | string | No | Filter by status: active, dismissed, acknowledged, in_progress, completed |
+
+**Auto-enriched Parameters:** `foundation` (vision, purpose, core values, target market), `goals` (with progress), `strategies` (linked to goals), `measures` (with current/target values), `recent_actions`, `open_issues`
+
+**Core Premise:**
+
+Purpose-driven businesses aligned with their values result in:
+- Engaged employees who are motivated and productive
+- Loyal customers who trust and advocate for the brand
+- Improved bottom line through sustainable growth
+
+**KISS Framework:**
+
+Each insight is categorized using KISS:
+- **KEEP**: What's working well and aligned with purpose/values (continue doing)
+- **IMPROVE**: What's partially working but needs optimization
+- **START**: What's missing that should be initiated
+- **STOP**: What's misaligned or counterproductive (cease doing)
+
+**Response Model:** `InsightsGenerationResponse`
+
+**Response Payload Structure:**
+
+The LLM generates a list of insights (typically 5-10) in a single response. This is ephemeral data - the .NET backend handles persistence and adds system fields (id, status, timestamps).
+
+```typescript
+{
+  "insights": [
+    {
+      "title": "string",
+      "description": "string",
+      "category": "strategy" | "operations" | "finance" | "marketing" | "leadership" | "technology",
+      "priority": "critical" | "high" | "medium" | "low",
+      "kiss_category": "keep" | "improve" | "start" | "stop",
+      "alignment_impact": "string",
+      "business_impact": "low" | "medium" | "high",
+      "effort_required": "low" | "medium" | "high"
+    }
+    // ... 4-9 more insights
+  ]
+}
+```
+
+**Note:** System fields like `id`, `status`, `created_at`, `updated_at` are added by the .NET backend when persisting, not generated by the LLM.
+
+**Frontend Integration:**
+1. Call `/ai/execute-async` with `topic_id: "insights_generation"`
+2. Poll job status until complete
+3. Receive insights array from Python AI service (ephemeral, no persistence)
+4. **Persist to .NET Traction Service:** POST `/traction/api/v1/insights/batch` with insights array
+5. .NET backend adds: `id`, `tenantId`, `status` (default "active"), `createdAt`, `updatedAt`
+6. Subsequent page loads fetch from .NET backend via GET `/traction/api/v1/insights` (not Python AI)
+7. **Widget displays insights:** GET `/traction/api/v1/dashboard/widgets/ai-insights/data` with camelCase properties
+
+**Related Specifications:**
+- **Persistence & CRUD:** See [Coaching Insights API](../../user-app/traction-service/insights-api.md) for POST /batch, GET, PUT, DELETE endpoints
+- **Widget Display:** See [Dashboard Service - AI Insights Widget](../../user-app/dashboard-service.md#ai-insights-widget) for widget data endpoint

+
+**Notes:**
+
+- The AI analyzes current business state using measure data (current vs target values) to assess performance
+- Suggests KISS actions (Keep, Improve, Start, Stop) that maintain purpose-driven alignment
+- Each insight includes specific data references (goals, measures, strategies) in the description
+- `alignment_impact` explains how the insight affects values alignment, employee engagement, and bottom line
+- **IMPORTANT:** This endpoint generates NEW insights using LLM (costs money!) - cache results on frontend/backend

+```json
+{
+  "topic_id": "goal_intent_review",
+  "parameters": {
+    "current_intent": "Implement a customer success program",

+- **MEASURE**: Defines WHEN and HOW MUCH. Example: "Customer Retention Rate reaches 90% by Q4"
+
+**Functionality:**
+1. **Quality Review** (if current intent provided):
+   - Validates the intent is not a strategy or action
+   - Scores quality from 0-100
+   - Identifies if it lacks WHY component or is too action-focused
+2. **Intent Suggestions**: Generates exactly 3 intent variations that:
+   - Focus on desired outcomes (WHAT + WHY)
+   - Align with business vision, purpose, and core values
+   - Are specific enough to guide strategy but not prescriptive
+   - Are realistic yet ambitious
+
+**Response Model:** `GoalIntentReviewResponse`
+
+**Response Payload Structure:**
+
+```json

+      }
+    }
+  ]
+}
+```
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `qualityReview` | string \| null | Assessment of current intent (if provided), otherwise null |
+| `qualityScore` | number \| null | Quality score 0-100 (if current intent provided), otherwise null |
+| `suggestions` | array of IntentSuggestion | List of 3 intent statement variations |
+
+**IntentSuggestion Structure:**
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `title` | string | Descriptive label for this intent variation (5-100 chars) |
+| `intentStatement` | string | The suggested goal intent statement (20-300 chars) |

+|-------|------|-------------|
+| `vision` | string | How intent connects to business vision |
+| `purpose` | string | How intent serves business purpose |
+| `values` | array of string | How intent aligns with specific core values |
+
+**Quality Score Interpretation:**
+- **90-100**: Excellent intent - clear, aligned, outcome-focused
+- **70-89**: Good intent - minor improvements needed
+- **50-69**: Moderate intent - significant refinement required
+- **30-49**: Weak intent - may be too action-focused or misaligned
+- **0-29**: Poor intent - needs complete rework, likely a strategy or action
+
+**Usage Notes:**
+- Intent should describe desired END STATE, not actions to take
+- Avoid prescriptive language like "implement", "create", "launch" - these are strategies
+- Focus on business outcomes and value creation
+- The WHY component explains business rationale and expected impact

+# Coaching Session Workflow Guide
+
+**Version:** 3.0  
+**Last Updated:** February 12, 2026  
+**Status:** Active
+
+[← Back to Backend Integration](./backend-integration-unified-ai.md)
+
+---
+
+## Purpose
+
+This guide explains the coaching journey in human terms: how a session starts, pauses, resumes, and completes from a user experience perspective.
+
+**Technical API and payload contracts live in one place only:**
+- `docs/shared/Specifications/ai-user/backend-integration-unified-ai.md`
+- `docs/shared/Specifications/eventbridge/async-coaching-message-events.md`
+
+---
+
+## Session Lifecycle
+
+Coaching sessions move through these states:
+
+- **ACTIVE**: User can continue messaging
+- **PAUSED**: User paused or frontend treats an idle session as paused on reopen
+- **COMPLETED**: Conversation is done and results are available
+- **CANCELLED**: User cancelled the session
+- **ABANDONED**: Older session replaced by a fresh start
+
+The main lifecycle principle:
+- **Start means new conversation**
+- **Resume means continue existing conversation**
+
+---
+
+## User Journey
+
+### 1) User opens coaching
+
+The frontend checks if there is an existing session and whether there is a conflict with another user in the tenant.
+
+- If no session exists, user starts fresh.
+- If a resumable session exists, user chooses to resume or start new.
+- If there is a conflict, the UI blocks entry and shows guidance.
+
+### 2) User sends a message
+
+Message handling is asynchronous:
+
+- The API immediately accepts the request and returns a job identifier.
+- The backend processes the message in the background.
+- Frontend receives the result by WebSocket, or polling fallback.
+
+This avoids request timeouts on long model responses and keeps the UI responsive.
+
+### 3) Conversation continues or ends
+
+Each completed message indicates whether the conversation is final:
+
+- If not final, the user keeps chatting.
+- If final, the UI presents extracted results and closes or transitions the session.
+
+### 4) User pauses, resumes, or starts over
+
+- **Pause** explicitly blocks additional messages until resume.
+- **Resume** re-enters the existing session context.
+- **Start new** creates a fresh session and retires the old one.
+
+---
+
+## Idle and Pause Behavior
+
+Idle time is treated as a UX signal, not a hard failure for active work:
+
+- A user who still has an active context can continue conversation flow.
+- On re-entry, frontend can present the session as paused and offer resume/new options.
+
+---
+
+## Operational Notes
+
+- Sessions have TTL-based cleanup.
+- Async jobs are temporary and used for status tracking and delivery.
+- Frontend should treat job completion events idempotently.
+
+---
+
+## Quick Checklist
+
+- Frontend checks session status before opening coaching UI
+- Frontend handles resume vs start-new explicitly
+- Message send uses async job flow
+- Completion handling uses finality flag + result payload
+- Pause/resume actions are reflected in UI state

+# Async Coaching Message Events - Frontend Integration Specification
+
+**Version**: 1.3.0  
+**Date**: February 10, 2026  
+**Related Issue**: #222  
+**Target Audience**: Frontend Developers, .NET Backend Team
+
+## Overview
+
+This specification defines the complete async pattern for coaching conversation messages, including HTTP APIs, WebSocket events, error handling, and polling fallback. Messages are processed asynchronously (5s - 5min) to avoid API Gateway 30s timeout.
+
+**Single Source of Truth**: This document contains all contracts needed for frontend implementation.
+
+## Field Naming Conventions
+
+### HTTP Responses (FastAPI - snake_case)
+
+All HTTP request/response bodies use **`snake_case`**:
+
+- `job_id`, `session_id`, `is_final`, `max_turns`, `message_count`, `error_code`, `processing_time_ms`, `estimated_duration_ms`
+
+**Example**:
+```json
+{
+  "job_id": "uuid",
+  "is_final": false,
+  "max_turns": 10
+}
+```
+
+### WebSocket Payloads (EventBridge - camelCase)
+
+All WebSocket event payloads use **`camelCase`**:
+
+- `jobId`, `sessionId`, `isFinal`, `maxTurns`, `messageCount`, `errorCode`, `eventType`
+
+**Example**:
+```json
+{
+  "jobId": "uuid",
+  "isFinal": false,
+  "maxTurns": 10
+}
+```
+
+### Summary
+
+| Transport | Casing | Fields |
+|-----------|--------|--------|
+| **HTTP (POST/GET)** | `snake_case` | `job_id`, `is_final`, `error_code` |
+| **WebSocket Events** | `camelCase` | `jobId`, `isFinal`, `errorCode` |
+
+### Why Async Pattern?
+
+**Problem**: Coaching AI responses can take 20-90 seconds due to:
+- Complex conversation context processing
+- Prompt cache writes (20-30s first response)
+- Final message extraction with structured output
+
+**Solution**: Return 202 Accepted immediately, process async, deliver via WebSocket
+
+### Message Flow

+
+## API Contracts
+
+### POST /ai/coaching/message
+
+**Endpoint**:
+```
+POST /ai/coaching/message
+Authorization: Bearer <jwt_token>
+Content-Type: application/json
+```
+
+**Request**:
+```json
+{
+  "session_id": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
+  "message": "I value integrity and transparency"
+}
+```
+
+**Success Response - 202 Accepted** (ALWAYS):
+```json
+{
+  "success": true,
+  "data": {
+    "job_id": "550e8400-e29b-41d4-a716-446655440000",
+    "session_id": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
+    "status": "pending",
+    "estimated_duration_ms": 45000
+  },
+  "message": "Message job created, processing asynchronously"
+}
+```
+
+**Important**: This endpoint **ALWAYS returns 202 Accepted**. It never returns 200 with the assistant message.
+
+**Error Responses**:
+
+| HTTP Status | Error Code | Scenario | Retryable |
+|-------------|-----------|----------|-----------|
+| 422 | `JOB_VALIDATION_ERROR` | Empty message | No |
+| 422 | `SESSION_NOT_FOUND` | Session doesn't exist | No |
+| 400 | `SESSION_NOT_ACTIVE` | Session paused/completed/cancelled | No |
+| 403 | `SESSION_ACCESS_DENIED` | User doesn't own session | No |
+| 422 | `MAX_TURNS_REACHED` | Hit conversation limit | No |
+| 410 | `SESSION_IDLE_TIMEOUT` | Session expired from inactivity | No |
+| 500 | `INTERNAL_ERROR` | Server error | Yes (after 30s) |
+
+**Example Error**:
+```json
+{
+  "detail": {
+    "code": "SESSION_NOT_ACTIVE",
+    "message": "Session is not active (status: completed)"
+  }
+}
+```
+
+#### One Message In-Flight Policy
+
+⚠️ **CRITICAL**: Backend does NOT enforce "one message per session in-flight".
+
+**Frontend MUST implement client-side**:
+1. Track pending `job_id` per session (localStorage)
+2. Disable send button while job pending
+3. Only enable after `ai.message.completed` or `ai.message.failed`
+4. On page reload: check localStorage for pending job → start polling
+
+**Future**: Backend may add `SESSION_BUSY` (409 Conflict) validation.
+
+### GET /ai/coaching/message/{job_id}
+
+**Endpoint** (polling fallback):
+```
+GET /ai/coaching/message/{job_id}
+Authorization: Bearer <jwt_token>
+```
+
+**Use Case**: Fallback when WebSocket unavailable or for debugging.
+
+#### State: pending
+
+```json
+{
+  "success": true,
+  "data": {
+    "job_id": "550e8400-e29b-41d4-a716-446655440000",
+    "session_id": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
+    "status": "pending",
+    "message": null,
+    "is_final": null,
+    "turn": null,
+    "max_turns": null,
+    "message_count": null,
+    "result": null,
+    "error": null,
+    "processing_time_ms": null
+  },
+  "message": "Job status: pending"
+}
+```
+
+#### State: processing
+
+```json
+{
+  "success": true,
+  "data": {
+    "job_id": "550e8400-e29b-41d4-a716-446655440000",
+    "session_id": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
+    "status": "processing",
+    "message": null,
+    "is_final": null,
+    "turn": null,
+    "max_turns": null,
+    "message_count": null,
+    "result": null,
+    "error": null,
+    "processing_time_ms": null
+  },
+  "message": "Job status: processing"
+}
+```
+
+#### State: completed (non-final turn)
+
+```json
+{
+  "success": true,
+  "data": {
+    "job_id": "550e8400-e29b-41d4-a716-446655440000",
+    "session_id": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
+    "status": "completed",
+    "message": "That's wonderful! Integrity shows up in how you communicate transparently with your team...",
+    "is_final": false,
+    "turn": 3,
+    "max_turns": 10,
+    "message_count": 6,
+    "result": null,
+    "error": null,
+    "processing_time_ms": 12450
+  },
+  "message": "Job status: completed"
+}
+```
+
+✅ **Note**: `turn`, `max_turns`, and `message_count` are included in polling responses for parity with WebSocket completion semantics.
+
+#### State: completed (final turn with extraction)
+
+```json
+{
+  "success": true,
+  "data": {
+    "job_id": "550e8400-e29b-41d4-a716-446655440000",
+    "session_id": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
+    "status": "completed",
+    "message": "Thank you for this wonderful conversation! Here are your three core values...",
+    "is_final": true,
+    "turn": 10,
+    "max_turns": 10,
+    "message_count": 20,
+    "result": {
+      "identified_values": [
+        "Integrity: Transparent communication",
+        "Growth: Continuous learning",
+        "Innovation: Creative problem-solving"
+      ],
+      "extraction_type": "core_values",
+      "confidence_score": 0.95,
+      "metadata": {
+        "model_used": "claude-3-5-haiku",
+        "extraction_success": true
+      }
+    },
+    "error": null,
+    "processing_time_ms": 18720
+  },
+  "message": "Job status: completed"
+}
+```
+
+#### State: failed
+
+```json
+{
+  "success": true,
+  "data": {
+    "job_id": "550e8400-e29b-41d4-a716-446655440000",
+    "session_id": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
+    "status": "failed",
+    "message": null,
+    "is_final": null,
+    "turn": null,
+    "max_turns": null,
+    "message_count": null,
+    "result": null,
+    "error": "Session not found: f47ac10b-58cc-4372-a567-0e02b2c3d479",
+    "processing_time_ms": 2100
+  },
+  "message": "Job status: failed"
+}
+```
+
+#### Job Not Found (after 24hr TTL)
+
+**Status**: `404 Not Found`
+
+```json
+{
+  "detail": {
+    "code": "JOB_NOT_FOUND",
+    "message": "Message job not found: {job_id}"
+  }
+}
+```
+
+---
+
+## Completion & Extraction Semantics
+
+### When is_final = true with result = null?
+
+**Possible**: `is_final` can be `true` with `result` being `null` or containing error fields.
+
+#### Scenario 1: Extraction Parsing Failed
+
+Event still sends as `ai.message.completed` (NOT `ai.message.failed`):
+
+```json
+{
+  "eventType": "ai.message.completed",
+  "jobId": "uuid",
+  "data": {
+    "message": "Thank you for sharing your values...",
+    "isFinal": true,
+    "result": {
+      "parse_error": "Expecting value: line 1 column 1 (char 0)",
+      "raw_response": "Here are the values:\n- Integrity\n- Growth\n- Innovation"
+    }
+  }
+}
+```
+
+**Frontend Action**:
+- Check if `result.parse_error` or `result.validation_error` exists
+- Show completion UI with warning: "We had trouble extracting your responses. Please review manually."
+
+#### Scenario 2: Extraction Model Not Configured
+
+```json
+{
+  "isFinal": true,
+  "result": {}  // Empty object
+}
+```
+
+**Frontend Action**: Show completion message without extraction results.
+
+### When does ai.message.failed occur?
+
+Only for **execution failures before message generation**:
+
+- `SESSION_NOT_FOUND`
+- `SESSION_ACCESS_DENIED`
+- `SESSION_NOT_ACTIVE`
+- `SESSION_IDLE_TIMEOUT`
+- `MAX_TURNS_REACHED`
+- `LLM_TIMEOUT`
+- `LLM_ERROR`
+- `INTERNAL_ERROR`
+
+**NOT for extraction failures** - those still return `ai.message.completed` with error fields in `result`.
+

+| `SESSION_NOT_FOUND` | "Session not found. Please start a new conversation." | No | Clear session, show start button |
+| `SESSION_ACCESS_DENIED` | "You don't have access to this session." | No | Redirect to home |
+| `SESSION_NOT_ACTIVE` | "This session is no longer active." | No | Show resume or restart options |
+| `SESSION_IDLE_TIMEOUT` | "Session expired due to inactivity." | No | Show restart button |
+| `MAX_TURNS_REACHED` | "Conversation limit reached." | No | Show completion message |
+| `JOB_VALIDATION_ERROR` | "Invalid request. Please try again." | No | Log error, show generic message |
+| `PARAMETER_VALIDATION` | "Invalid parameters. Please try again." | No | Log error, show generic message |

+| `INTERNAL_ERROR` | "Something went wrong. Please try again." | Yes | Show retry button (wait 30s) |
+
+**Note**: `EXTRACTION_FAILED` does NOT appear in `ai.message.failed` events. Extraction failures return `ai.message.completed` with error fields in `result`.
+
+### Retry Strategy
+
+```typescript
+const getRetryDelay = (errorCode: string): number => {
+  switch (errorCode) {
+    case 'LLM_TIMEOUT':
+      return 0;  // Retry immediately
+    case 'LLM_ERROR':
+      return 10000;  // Wait 10 seconds
+    case 'INTERNAL_ERROR':
+      return 30000;  // Wait 30 seconds
+    default:
+      return -1;  // Not retryable
+  }
+};
+
+const handleError = (event: MessageFailedEvent, retryAttempt: number) => {
+  const delay = getRetryDelay(event.data.errorCode);
+  
+  if (delay < 0 || retryAttempt >= 3) {
+    // Show non-retryable error or max retries reached
+    showError(getUserMessage(event.data.errorCode));
+    return;
+  }
+  
+  // Show retryable error with countdown
+  showRetryableError(getUserMessage(event.data.errorCode), delay / 1000);
+  
+  setTimeout(() => {
+    // Retry sending the message
+    retryMessage(sessionId, originalMessage, retryAttempt + 1);
+  }, delay);
+};
+```
+
+## Frontend Implementation
+
+### React/TypeScript Example
+
+```typescript
+interface CoachingMessageAPI {

+
+### UI State Management
+
+```typescript
+// Processing state
+const [isProcessing, setIsProcessing] = useState(false);
+const [processingJobId, setProcessingJobId] = useState<string | null>(null);
+
+// When sending message
+<button 
+  onClick={() => handleSendMessage(userInput)}
+  disabled={isProcessing}
+>
+  {isProcessing ? 'AI is thinking...' : 'Send'}
+</button>
+
+// Show processing indicator
+{isProcessing && (
+  <div className="processing-indicator">
+    <Spinner />
+    <span>AI is thinking...</span>
+    <span className="text-muted">This may take up to 90 seconds</span>
+  </div>
+)}
+```
+
+### Polling Fallback (No WebSocket)
+
+```typescript
+// For systems without WebSocket support
+const pollMessageStatus = async (jobId: string) => {
+  const maxAttempts = 60; // 5 minutes with 5s intervals
+  let attempts = 0;
+  
+  while (attempts < maxAttempts) {
+    try {
+      const response = await fetch(`/ai/coaching/message/${jobId}`);
+      const data = await response.json();
+      
+      if (data.data.status === 'completed') {
+        handleMessageCompleted({
+          eventType: 'ai.message.completed',
+          jobId: jobId,
+          sessionId: data.data.session_id,
+          data: {
+            message: data.data.message,
+            isFinal: data.data.is_final,
+            turn: data.data.turn,
+            maxTurns: data.data.max_turns,
+            messageCount: data.data.message_count,
+            result: data.data.result
+          }
+        });
+        return;
+      }
+      
+      if (data.data.status === 'failed') {

+      }
+      
+      // Still processing, wait 5s
+      await new Promise(resolve => setTimeout(resolve, 5000));
+      attempts++;
+      
+    } catch (error) {
+      showError('Failed to check message status');
+      return;
+    }
+  }
+  
+  // Timeout after 5 minutes
+  showError('Message processing timed out');
+};
+```
+
+## Event Type Field
+
+**All WebSocket events use the `eventType` field** to identify the event type.
+
+**Event types**:
+
+| Pattern | Event Type | Description |
+|---------|-----------|-------------|
+| **Async Messages** (Conversations) | `ai.message.completed` | Coach response ready |
+| **Async Messages** (Conversations) | `ai.message.failed` | Message processing failed |
+| **Single-shot Jobs** (Analysis) | `ai.job.completed` | Analysis job completed |
+| **Single-shot Jobs** (Analysis) | `ai.job.failed` | Analysis job failed |
+
+**WebSocket handler example**:
+
+```typescript
+const handleWebSocketMessage = (payload: any) => {
+  switch (payload.eventType) {
+    case 'ai.message.completed':
+    case 'ai.message.failed':
+      handleCoachingMessage(payload);
+      break;
+      
+    case 'ai.job.completed':
+    case 'ai.job.failed':
+      handleJobCompletion(payload);
+      break;
+      
+    default:
+      console.warn('Unknown event type:', payload.eventType);
+  }
+};
+```
+
+## Testing
+
+### Manual Testing (Frontend Dev)
+
+1. **Send Message**:
+   ```bash
+   curl -X POST https://api.dev.purposepath.ai/ai/coaching/message \
+     -H "Authorization: Bearer $TOKEN" \
+     -H "Content-Type: application/json" \
+     -d '{"session_id":"your-session-id","message":"Tell me about values"}'
+   ```
+
+2. **Check Response**:
+   - Verify `202 Accepted` status
+   - Save `job_id` from response
+
+3. **Monitor WebSocket**:
+   - Open browser DevTools → Network → WS
+   - Wait for `ai.message.completed` event
+   - Verify `jobId` matches saved value
+
+4. **Test Error Handling**:
+   ```bash
+   # Invalid session ID
+   curl -X POST ... -d '{"session_id":"invalid","message":"test"}'
+   ```
+   - Verify `ai.message.failed` event received
+   - Check `errorCode` is `"SESSION_NOT_FOUND"`
+
+### Integration Checklist
+
+- [ ] POST /message returns 202 with `job_id`
+- [ ] "Processing" UI shows after POST
+- [ ] WebSocket receives `ai.message.completed` event
+- [ ] Complete message displays correctly
+- [ ] `isFinal` flag triggers completion flow
+- [ ] Error events show user-friendly messages
+- [ ] Session cleared on `SESSION_NOT_FOUND`
+- [ ] Polling fallback works without WebSocket
+
+## .NET Backend Notes
+
+The .NET WebSocket service must forward EventBridge events to frontend clients:
+
+**Subscribe to EventBridge events**:
+- `ai.message.completed` (detail-type)
+- `ai.message.failed` (detail-type)
+- Filter by `detail.stage` matching environment
+
+**Forward to WebSocket clients**:
+- Route by `detail.tenantId` + `detail.userId`
+- Send complete EventBridge `detail` object as WebSocket message
+- Frontend expects this exact structure
+
+**Do NOT forward**:
+- `ai.message.created` events (internal worker trigger only)
+
+## Migration from Synchronous Pattern
+
+### Before (Synchronous)
+
+```typescript
+// POST returned complete response after 20-90s
+const response = await fetch('/ai/coaching/message', {
+  method: 'POST',
+  body: JSON.stringify({ session_id, message })
+});
+
+// HTTP 200 with complete message
+const data = await response.json();
+displayMessage(data.message);  // Full response immediately
+```
+
+**Problems**:
+- API Gateway 30s timeout → 503 errors for long responses
+- User waited with blocking UI
+- No progress indication
+
+### After (Asynchronous)
+
+```typescript
+// POST returns immediately
+const response = await fetch('/ai/coaching/message', {
+  method: 'POST',
+  body: JSON.stringify({ session_id, message })
+});
+
+// HTTP 202 with job_id
+const data = await response.json();
+showProcessing(data.job_id);
+
+// Wait for WebSocket event (5s - 5min later)
+websocket.on('message', (event) => {
+  if (event.eventType === 'ai.message.completed') {
+    hideProcessing();
+    displayMessage(event.data.message);
+  }
+});
+```
+
+**Benefits**:
+- No API Gateway timeout (202 returns instantly)
+- Non-blocking UI with progress indicator
+- Lambda can process for up to 5 minutes
+- Better error handling

+
+## Implementation Guidelines
+
+### Event Ordering & Deduplication
+
+**Ordering Guarantees**:
+- Events for the **same `jobId`** are delivered in order
+- Events across different jobs have no ordering guarantee
+- Sequence: `ai.message.created` (internal) → `ai.message.completed` OR `ai.message.failed` (never both)
+
+**Deduplication**:
+- EventBridge may deliver duplicate events (rare, but possible)
+- **Frontend must handle idempotently**: Check if `jobId` already processed before updating UI
+- **One terminal event per job**: Either `completed` OR `failed`, never both
+
+**Routing**:
+- Route by `jobId` ONLY (not sessionId)
+- Multiple pending jobs per session are possible (since backend doesn't enforce one-in-flight)
+
+```typescript
+const processedJobs = new Set<string>();
+
+const handleWebSocketEvent = (event: MessageCompletedEvent | MessageFailedEvent) => {
+  // Deduplication check
+  if (processedJobs.has(event.jobId)) {
+    console.warn('Duplicate event for job:', event.jobId);
+    return;
+  }
+  
+  processedJobs.add(event.jobId);
+  
+  // Process event...
+};
+```
+
+### Retention & TTL
+
+**Job Retention**: 24 hours from creation
+
+After 24 hours:
+- `GET /message/{job_id}` returns `404 JOB_NOT_FOUND`
+- Jobs automatically deleted from DynamoDB
+- Frontend should not store `job_id` beyond 24 hours
+
+**Session Retention**: No automatic expiration
+
+- Paused sessions never expire automatically
+- Idle timeout only marks session inactive (doesn't delete)
+- Sessions persist until explicitly completed or cancelled
+
+**Recommendation**: Clear `job_id` from localStorage after receiving terminal event.
+
+### Polling Strategy
+
+**When to use**:
+- Primary: WebSocket event delivery
+- Fallback: Polling when WebSocket disconnected or safety timeout exceeded
+
+**Recommended polling**:
+
+```typescript
+const pollMessageStatus = async (jobId: string) => {
+  const POLL_INTERVAL = 5000;  // 5 seconds
+  const MAX_DURATION = 300000;  // 5 minutes
+  const startTime = Date.now();
+  
+  while (Date.now() - startTime < MAX_DURATION) {
+    try {
+      const response = await fetch(`/ai/coaching/message/${jobId}`);
+      const data = await response.json();
+      
+      if (data.data.status === 'completed') {
+        handleCompleted(data.data);
+        return;
+      }
+      
+      if (data.data.status === 'failed') {
+        handleFailed(data.data);
+        return;
+      }
+      
+      // Still processing, wait before next poll
+      await sleep(POLL_INTERVAL);
+      
+    } catch (error) {
+      console.error('Polling error:', error);
+      await sleep(POLL_INTERVAL);
+    }
+  }
+  
+  // Timeout after 5 minutes
+  showError('Request timed out. Please try again.');
+};
+```
+
+**Safety timeout for WebSocket**:
+
+```typescript
+// Start polling if no WebSocket event received after 90s
+const safetyTimeout = setTimeout(() => {
+  if (jobStillPending) {
+    console.warn('No WebSocket event after 90s, starting polling...');
+    startPolling(jobId);
+  }
+}, 90000);
+
+// Cancel timeout when WebSocket event arrives
+websocket.addEventListener('message', (event) => {
+  clearTimeout(safetyTimeout);
+  // process event...
+});
+```
+
+**Key Points**:
+- Interval: 5 seconds (balance between latency and server load)
+- Max duration: 5 minutes (matches Lambda timeout)
+- Always prefer WebSocket over polling
+- Use polling as fallback only
+
+---
+
+## Frequently Asked Questions
+
+### Q: What if WebSocket connection is lost?
+
+Use polling fallback with `GET /message/{job_id}`:
+
+```typescript
+// Detect WebSocket disconnect
+websocket.onclose = () => {
+  if (processingJobId) {
+    startPolling(processingJobId);
+  }
+};
+
+const startPolling = async (jobId: string) => {
+  const interval = setInterval(async () => {
+    const response = await fetch(`/ai/coaching/message/${jobId}`);
+    const data = await response.json();
+    
+    if (data.data.status === 'completed' || data.data.status === 'failed') {
+      clearInterval(interval);
+      handleCompletion(data);
+    }
+  }, 5000);  // Poll every 5 seconds
+};
+```
+
+### Q: What if user closes browser during processing?
+
+- Job continues in Lambda (no automatic cancellation)
+- Result saved in DynamoDB
+- Next time user opens app, check for pending jobs:
+  ```typescript
+  useEffect(() => {
+    // On mount, check for pending jobs
+    const pendingJob = localStorage.getItem('pendingJobId');
+    if (pendingJob) {
+      startPolling(pendingJob);
+    }
+  }, []);
+  ```
+
+### Q: How long should "Processing" UI show?
+
+- **Minimum**: 1 second (avoid flash)
+- **Average**: 20-30 seconds
+- **Maximum**: Display "This is taking longer than usual" after 60s
+- **Timeout**: Show error after 5 minutes
+
+```typescript
+useEffect(() => {
+  if (!isProcessing) return;
+  
+  const warningTimer = setTimeout(() => {
+    showWarning('This is taking longer than usual...');
+  }, 60000);  // 1 minute
+  
+  const timeoutTimer = setTimeout(() => {
+    showError('Request timed out. Please try again.');
+    setIsProcessing(false);
+  }, 300000);  // 5 minutes
+  
+  return () => {
+    clearTimeout(warningTimer);
+    clearTimeout(timeoutTimer);
+  };
+}, [isProcessing]);
+```
+
+### Q: Can user send another message while processing?
+
+Recommended: **No** - Disable send button while `isProcessing === true`
+
+```typescript
+<button 
+  onClick={handleSend}
+  disabled={isProcessing || !userInput.trim()}
+>
+  {isProcessing ? 'AI is thinking...' : 'Send'}
+</button>
+```
+
+### Q: What's `estimated_duration_ms` for?
+
+Optional: Show user estimated wait time from 202 response
+
+```typescript
+const { estimated_duration_ms } = response;  // e.g., 25000 (25s)
+
+if (estimated_duration_ms > 30000) {
+  showNotice('This may take up to 90 seconds');
+}
+```
+
+---
+
+## Quick Reference Checklist
+
+✅ HTTP responses use `snake_case` (job_id, is_final, max_turns)  
+✅ WebSocket payloads use `camelCase` (jobId, isFinal, maxTurns)  
+✅ POST /message **always** returns `202` (never `200`)  
+✅ Frontend enforces one message in-flight (backend doesn't validate)  
+✅ Route WebSocket events by `jobId` only (not sessionId)  
+✅ Handle duplicate events idempotently (check processedJobs Set)  
+✅ Extraction failures return `ai.message.completed` with error fields (NOT `ai.message.failed`)  
+✅ Poll only as fallback (5s interval, 5min max, prefer WebSocket)  
+✅ Job TTL is 24 hours  
+✅ Paused sessions don't expire automatically  
+✅ Retry failed jobs with delays: LLM_TIMEOUT (0s), LLM_ERROR (10s), INTERNAL_ERROR (30s)  
+✅ Use 90s WebSocket safety timeout before starting polling

+# Real-Time Hooks Usage Guide
+
+**Phase 3: State Integration Complete**
+
+This guide shows how to use the real-time WebSocket hooks in your React components.
+
+## Available Hooks
+
+### Core Hooks
+
+1. **`useRealtimeEvent`** - Subscribe to specific event types
+2. **`useRealtimeConnection`** - Get connection status
+3. **`useRealtime`** - Full context access (connection + subscriptions)
+
+### Specialized Hooks
+
+4. **`useGoalActivity`** - Subscribe to goal-specific events
+5. **`useRealtimeGoals`** - Subscribe to all goal events
+
+---
+
+## Installation
+
+All hooks are exported from `src/hooks/realtime.ts`:
+
+```typescript
+import { 
+  useRealtimeEvent,
+  useRealtimeConnection,
+  useGoalActivity,
+  useRealtimeGoals 
+} from '../hooks/realtime';
+```
+
+---
+
+## Examples
+
+### 1. Subscribe to Specific Events
+
+```typescript
+import { useRealtimeEvent } from '../hooks/realtime';
+import { useQueryClient } from '@tanstack/react-query';
+import { toast } from 'sonner';
+
+function GoalList() {
+  const queryClient = useQueryClient();
+
+  // Invalidate cache when goals are created
+  useRealtimeEvent({
+    eventType: 'goal.created',
+    onEvent: (message) => {
+      console.log('New goal:', message.data.title);
+      queryClient.invalidateQueries({ queryKey: ['goals'] });
+      toast.success('New goal created');
+    }
+  });
+
+  // Celebrate goal completions
+  useRealtimeEvent({
+    eventType: 'goal.completed',
+    onEvent: (message) => {
+      toast.success('Goal completed! 🎉', {
+        description: message.data.finalNotes
+      });
+      queryClient.invalidateQueries({ queryKey: ['goals'] });
+    }
+  });
+
+  return <div>{/* Goal list UI */}</div>;
+}
+```
+
+### 2. Goal-Specific Activity Feed
+
+```typescript
+import { useGoalActivity } from '../hooks/realtime';
+import { useState } from 'react';
+
+function GoalRoom({ goalId }: { goalId: string }) {
+  const [activities, setActivities] = useState<Activity[]>([]);
+
+  useGoalActivity({
+    goalId,
+    onActivityCreated: (data) => {
+      // Add new activity to the feed
+      setActivities(prev => [{
+        id: data.activityId,
+        type: data.activityType,
+        description: data.description,
+        timestamp: data.createdAt
+      }, ...prev]);
+    },
+    onCompleted: (data) => {
+      toast.success('Goal completed! 🎉');
+    },
+    onPaused: (data) => {
+      toast.info('Goal paused', {
+        description: data.reason
+      });
+    }
+  });
+
+  return (
+    <div>
+      <h2>Activity Feed</h2>
+      {activities.map(activity => (
+        <ActivityCard key={activity.id} activity={activity} />
+      ))}
+    </div>
+  );
+}
+```
+
+### 3. Dashboard with All Goal Events
+
+```typescript
+import { useRealtimeGoals } from '../hooks/realtime';
+import { useQueryClient } from '@tanstack/react-query';
+
+function Dashboard() {
+  const queryClient = useQueryClient();
+
+  useRealtimeGoals({
+    onGoalCreated: () => {
+      queryClient.invalidateQueries({ queryKey: ['dashboard-stats'] });
+    },
+    onGoalCompleted: (data) => {
+      toast.success(`Goal "${data.goalId}" completed! 🎉`);
+      queryClient.invalidateQueries({ queryKey: ['dashboard-stats'] });
+    },
+    onAnyGoalEvent: (eventType, data) => {
+      console.log('Goal event:', eventType, data);
+    }
+  });
+
+  return <div>{/* Dashboard UI */}</div>;
+}
+```
+
+### 4. Connection Status Indicator
+
+```typescript
+import { useRealtimeConnection } from '../hooks/realtime';
+
+function ConnectionIndicator() {
+  const { isConnected, connectionState } = useRealtimeConnection();
+
+  if (!isConnected) {
+    return (
+      <div className="flex items-center gap-2 text-sm text-gray-500">
+        <div className="w-2 h-2 rounded-full bg-red-500" />
+        <span>Offline</span>
+      </div>
+    );
+  }
+
+  return (
+    <div className="flex items-center gap-2 text-sm text-green-600">
+      <div className="w-2 h-2 rounded-full bg-green-500 animate-pulse" />
+      <span>Live</span>
+    </div>
+  );
+}
+```
+
+### 5. Conditional Subscriptions
+
+```typescript
+function OperationsPage() {
+  const { isAuthenticated } = useAuth();
+  const queryClient = useQueryClient();
+
+  // Only subscribe when authenticated
+  useRealtimeEvent({
+    eventType: 'action.completed',
+    enabled: isAuthenticated, // Conditional subscription
+    onEvent: (message) => {
+      queryClient.invalidateQueries({ queryKey: ['actions'] });
+    }
+  });
+
+  return <div>{/* Operations UI */}</div>;
+}
+```
+
+### 6. Multiple Event Subscriptions
+
+```typescript
+function IssuesBoard() {
+  const queryClient = useQueryClient();
+
+  // Subscribe to issue created
+  useRealtimeEvent({
+    eventType: 'issue.created',
+    onEvent: (message) => {
+      const { severity } = message.data;
+      
+      if (severity === 'critical') {
+        toast.error('Critical issue created!', {
+          description: message.data.title
+        });
+      }
+      
+      queryClient.invalidateQueries({ queryKey: ['issues'] });
+    }
+  });
+
+  // Subscribe to issue status changes
+  useRealtimeEvent({
+    eventType: 'issue.status_changed',
+    onEvent: (message) => {
+      if (message.data.newStatus === 'resolved') {
+        toast.success('Issue resolved');
+      }
+      queryClient.invalidateQueries({ queryKey: ['issues'] });
+    }
+  });
+
+  return <div>{/* Issues board UI */}</div>;
+}
+```
+
+---
+
+## Best Practices
+
+### 1. Cache Invalidation
+
+Always invalidate React Query caches when data changes:
+
+```typescript
+useRealtimeEvent({
+  eventType: 'goal.created',
+  onEvent: () => {
+    // Invalidate specific query
+    queryClient.invalidateQueries({ queryKey: ['goals'] });
+    
+    // Or invalidate multiple related queries
+    queryClient.invalidateQueries({ queryKey: ['goals'] });
+    queryClient.invalidateQueries({ queryKey: ['dashboard-stats'] });
+  }
+});
+```
+
+### 2. Event Filtering
+
+Filter events in the callback to avoid unnecessary updates:
+
+```typescript
+useRealtimeEvent({
+  eventType: 'action.status_changed',
+  onEvent: (message) => {
+    // Only handle if it's for our specific goal
+    if (message.data.goalId === currentGoalId) {
+      refetchActions();
+    }
+  }
+});
+```
+
+### 3. Toast Notifications
+
+Use appropriate toast types for different events:
+
+```typescript
+// Success for positive events
+toast.success('Goal completed! 🎉');
+
+// Error for critical issues
+toast.error('Critical issue reported');
+
+// Info for status changes
+toast.info('Goal paused');
+
+// Warning for important notifications
+toast.warning('Measure threshold breached');
+```
+
+### 4. Cleanup
+
+Hooks automatically clean up subscriptions when components unmount. No manual cleanup needed!
+
+### 5. Feature Flag
+
+Always respect the feature flag - hooks automatically disable when `REACT_APP_FEATURE_REALTIME=false`.
+
+---
+
+## Optimistic Updates
+
+When making mutations, use optimistic updates for instant UI feedback:
+
+```typescript
+import { useMutation, useQueryClient } from '@tanstack/react-query';
+
+function useCompleteGoal() {
+  const queryClient = useQueryClient();
+
+  return useMutation({
+    mutationFn: (goalId: string) => goalService.complete(goalId),
+    
+    // Optimistic update
+    onMutate: async (goalId) => {
+      await queryClient.cancelQueries({ queryKey: ['goals', goalId] });
+      
+      const previousGoal = queryClient.getQueryData(['goals', goalId]);
+      
+      // Update UI immediately
+      queryClient.setQueryData(['goals', goalId], (old: any) => ({
+        ...old,
+        status: 'completed'
+      }));
+      
+      return { previousGoal };
+    },
+    
+    // Rollback on error
+    onError: (err, goalId, context) => {
+      queryClient.setQueryData(['goals', goalId], context.previousGoal);
+      toast.error('Failed to complete goal');
+    },
+    
+    // Refetch on success (server will send WebSocket event too)
+    onSuccess: () => {
+      toast.success('Goal completed! 🎉');
+    }
+  });
+}
+```
+
+---
+
+## Troubleshooting
+
+### Events Not Received
+
+1. Check feature flag: `REACT_APP_FEATURE_REALTIME=true`
+2. Check connection: Use `<RealtimeDebugPanel />` in development
+3. Check WebSocket URL: `REACT_APP_REALTIME_WS_URL` is set
+4. Check authentication: Must be logged in
+5. Check browser console for errors
+
+### Duplicate Events
+
+Ensure you're not subscribing multiple times:
+
+```typescript
+// ❌ Bad - subscribes on every render
+function BadComponent() {
+  const [data, setData] = useState([]);
+  
+  // This creates new subscription on every render!
+  useRealtimeEvent({
+    eventType: 'goal.created',
+    onEvent: () => setData([...data, newItem])
+  });
+}
+
+// ✅ Good - stable callback reference
+function GoodComponent() {
+  const queryClient = useQueryClient();
+  
+  useRealtimeEvent({
+    eventType: 'goal.created',
+    onEvent: () => {
+      queryClient.invalidateQueries({ queryKey: ['goals'] });
+    }
+  });
+}
+```
+
+### Connection Status
+
+Monitor connection in development:
+
+```typescript
+import { RealtimeDebugPanel } from '../contexts/RealtimeContext';
+
+function App() {
+  return (
+    <>
+      {process.env.NODE_ENV === 'development' && <RealtimeDebugPanel />}
+      {/* Rest of app */}
+    </>
+  );
+}
+```

+
+## Configuration
+
+### Environment Variables
+
+```bash
+# Enable/disable real-time features
+REACT_APP_FEATURE_REALTIME=true
+
+# WebSocket server URL
+REACT_APP_REALTIME_WS_URL=wss://api.dev.purposepath.app/realtime
+```
+
+### Environment-Specific URLs
+
+| Environment | WebSocket URL |
+|------------|---------------|
+| Development | `wss://api.dev.purposepath.app/realtime` |
+| Staging | `wss://api.staging.purposepath.app/realtime` |
+| Production | `wss://api.purposepath.app/realtime` |
+
+### Local Development
+
+For local development, use the mock WebSocket server:
+
+```bash
+# Start mock server
+npm run mock:ws
+
+# Configure frontend to use mock server
+REACT_APP_REALTIME_WS_URL=ws://localhost:5055
+```
+
+---
+
+## Event Types
+
+### Event Message Structure
+
+All WebSocket events follow this structure:
+
+```typescript
+interface WebSocketMessage<T = any> {
+  type: string;              // Event type (e.g., 'goal.created')
+  data: T;                   // Event-specific payload
+  timestamp: string;         // ISO 8601 timestamp
+  eventId: string;           // Unique event identifier
+  tenantId: string;          // Tenant identifier
+}
+```

+| `measure.reading_created` | New Measure reading recorded | `MeasureReadingCreatedEventData` |
+
+### Authentication Events
+
+| Event Type | Description |
+|-----------|-------------|
+| `auth.success` | Authentication successful |
+| `auth.error` | Authentication failed |
+
+---
+
+## Usage Patterns
+
+### 1. Subscribe to Specific Events
+
+```typescript
+import { useRealtimeEvent } from '../hooks/realtime';
+import { useQueryClient } from '@tanstack/react-query';
+
+function GoalList() {
+  const queryClient = useQueryClient();
+
+  // Subscribe to goal created events
+  useRealtimeEvent({
+    eventType: 'goal.created',
+    onEvent: (message) => {
+      console.log('New goal created:', message.data.title);
+      
+      // Invalidate cache to trigger refetch
+      queryClient.invalidateQueries({ queryKey: ['goals'] });
+      
+      // Show toast notification
+      toast.success('New goal created');
+    }
+  });
+
+  return <div>{/* Goal list UI */}</div>;
+}
+```
+
+### 2. Goal-Specific Activity Feed
+
+```typescript
+import { useGoalActivity } from '../hooks/realtime';
+
+function GoalRoom({ goalId }: { goalId: string }) {
+  useGoalActivity({
+    goalId,
+    onCompleted: (data) => {
+      toast.success('Goal completed! 🎉');
+      refetchGoal();
+    },
+    onPaused: (data) => {
+      toast.info('Goal paused', {
+        description: data.reason
+      });
+    },
+    onActivityCreated: (data) => {
+      // Update activity feed
+      addActivity(data);
+    }
+  });
+
+  return <div>{/* Goal UI */}</div>;
+}
+```
+
+### 3. Connection Status
+
+```typescript
+import { useRealtimeConnection } from '../hooks/realtime';
+
+function ConnectionIndicator() {
+  const { isConnected, connectionState } = useRealtimeConnection();
+
+  return (
+    <div>
+      {isConnected ? (
+        <span className="text-green-600">● Live</span>
+      ) : (
+        <span className="text-gray-400">○ Offline</span>
+      )}
+    </div>
+  );
+}
+```
+
+### 4. Live Update Badges
+
+```typescript
+import { LiveBadge, useLiveBadge } from '../components/ui/LiveBadge';
+
+function GoalCard({ goal }: { goal: Goal }) {
+  const { showBadge, triggerBadge } = useLiveBadge();
+
+  useRealtimeEvent({
+    eventType: 'goal.completed',
+    onEvent: (message) => {
+      if (message.data.goalId === goal.id) {
+        triggerBadge(); // Show "Live" badge
+        refetch();
+      }
+    }
+  });
+
+  return (
+    <div className="goal-card">
+      <LiveBadge show={showBadge} />
+      {/* Goal content */}
+    </div>
+  );
+}
+```
+
+### 5. Toast Notifications
+
+```typescript
+import { realtimeToasts } from '../services/realtime-toasts';
+
+// In a component or hook
+useRealtimeEvent({
+  eventType: 'issue.created',
+  onEvent: (message) => {
+    realtimeToasts.issueCreated(message.data);
+    refetchIssues();
+  }
+});
+```
+
+### 6. Dashboard-Wide Subscriptions
+
+```typescript
+import { useRealtimeGoals } from '../hooks/realtime';
+
+function Dashboard() {
+  const queryClient = useQueryClient();
+
+  useRealtimeGoals({
+    onGoalCreated: () => {
+      queryClient.invalidateQueries({ queryKey: ['dashboard-stats'] });
+    },
+    onGoalCompleted: (data) => {
+      toast.success(`Goal completed! 🎉`);
+      queryClient.invalidateQueries({ queryKey: ['dashboard-stats'] });
+    },
+    onAnyGoalEvent: (eventType, data) => {
+      console.log('Goal event:', eventType);
+    }
+  });
+
+  return <div>{/* Dashboard UI */}</div>;
+}
+```
+
+---

+
+## Troubleshooting
+
+### Connection Issues
+
+**Problem:** WebSocket not connecting
+
+**Solutions:**
+1. Check feature flag: `REACT_APP_FEATURE_REALTIME=true`
+2. Verify WebSocket URL is correct
+3. Check browser console for errors
+4. Ensure user is authenticated
+5. Check network tab for WebSocket connection
+6. Verify backend WebSocket endpoint is running
+
+**Problem:** Frequent disconnections
+
+**Solutions:**
+1. Check network stability
+2. Verify keep-alive ping is working (every 8 minutes)
+3. Check for token expiration issues
+4. Review reconnection logs in console
+
+### Event Issues
+
+**Problem:** Events not being received
+
+**Solutions:**
+1. Check subscription is active (`useRealtimeEvent` mounted)
+2. Verify event type string matches exactly
+3. Check WebSocket connection is established
+4. Use `RealtimeDebugPanel` in development
+5. Check browser console for event logs
+
+**Problem:** Duplicate events
+
+**Solutions:**
+1. Ensure hook dependencies are stable
+2. Check component isn't remounting unnecessarily
+3. Verify subscription cleanup on unmount
+4. Use React DevTools to check render cycles
+
+### Performance Issues
+
+**Problem:** High memory usage
+
+**Solutions:**
+1. Check for memory leaks in event handlers
+2. Ensure proper cleanup of subscriptions
+3. Limit activity feed size (`maxActivities` prop)
+4. Review event handler complexity
+
+**Problem:** UI lag on events
+
+**Solutions:**
+1. Debounce cache invalidations
+2. Use optimistic updates for immediate feedback
+3. Batch React state updates
+4. Profile with React DevTools
+
+### Debug Tools
+
+#### RealtimeDebugPanel
+
+Shows connection stats in development:
+
+```typescript
+import { RealtimeDebugPanel } from '../contexts/RealtimeContext';
+
+// Add to App.tsx in development
+{process.env.NODE_ENV === 'development' && <RealtimeDebugPanel />}
+```
+
+#### Console Logging
+
+Enable verbose logging:
+
+```typescript
+// In RealtimeContext or components
+const debug = true;
+
+if (debug) {
+  console.log('[Realtime] Event received:', message);
+}
+```
+
+---
+
+## Best Practices
+
+### 1. Cache Invalidation
+
+Always invalidate React Query caches when data changes:
+
+```typescript
+useRealtimeEvent({
+  eventType: 'goal.created',
+  onEvent: () => {
+    // Specific queries
+    queryClient.invalidateQueries({ queryKey: ['goals'] });
+    queryClient.invalidateQueries({ queryKey: ['dashboard-stats'] });
+  }
+});
+```
+
+### 2. Event Filtering
+
+Filter events in callbacks to avoid unnecessary updates:
+
+```typescript
+useRealtimeEvent({
+  eventType: 'action.status_changed',
+  onEvent: (message) => {
+    // Only handle if relevant
+    if (message.data.goalId === currentGoalId) {
+      refetchActions();
+    }
+  }
+});
+```
+
+### 3. Optimistic Updates
+
+Use optimistic updates for instant UI feedback:
+
+```typescript
+const mutation = useMutation({
+  mutationFn: completeGoal,
+  onMutate: async (goalId) => {
+    // Cancel outgoing refetches
+    await queryClient.cancelQueries({ queryKey: ['goals', goalId] });
+    
+    // Snapshot previous value
+    const previous = queryClient.getQueryData(['goals', goalId]);
+    
+    // Optimistically update
+    queryClient.setQueryData(['goals', goalId], (old) => ({
+      ...old,
+      status: 'completed'
+    }));
+    
+    return { previous };
+  },
+  onError: (err, variables, context) => {
+    // Rollback on error
+    queryClient.setQueryData(['goals', variables], context.previous);
+  },
+  onSuccess: () => {
+    // Server will send WebSocket event confirming
+    toast.success('Goal completed! 🎉');
+  }
+});
+```
+
+### 4. Subscription Cleanup
+
+Hooks automatically cleanup, but manual subscriptions need cleanup:
+
+```typescript
+useEffect(() => {
+  const subscriptionId = realtimeWebSocket.subscribe('goal.created', handler);
+  
+  return () => {
+    realtimeWebSocket.unsubscribe(subscriptionId);
+  };
+}, []);
+```
+
+### 5. Error Handling
+
+Always handle errors gracefully:
+
+```typescript
+useRealtimeEvent({
+  eventType: 'goal.created',
+  onEvent: (message) => {
+    try {
+      // Process event
+      processGoal(message.data);
+    } catch (error) {
+      console.error('Failed to process goal event:', error);
+      toast.error('Failed to update goal');
+    }
+  }
+});
+```
+
+### 6. Feature Flag Respect
+
+Always respect the feature flag:
+
+```typescript
+const { isEnabled } = useRealtimeConnection();
+
+if (!isEnabled) {
+  // Fallback to polling or show offline indicator
+  return <OfflineMode />;
+}
+```
+
+### 7. Memory Management
+
+Keep activity feeds and event lists bounded:
+
+```typescript
+<GoalActivityFeed 
+  goalId={goalId}
+  maxActivities={50}  // Limit size
+  autoScroll={true}
+/>
+```
+
+---
+
+## Performance Considerations
+
+### Connection Management
+
+- Single WebSocket connection shared across app
+- Automatic reconnection with exponential backoff
+- Keep-alive ping every 8 minutes
+- Connection pooling not needed (single connection)
+
+### Event Processing
+
+- Events processed in order received
+- Subscription callbacks executed synchronously
+- Use React state batching for multiple updates
+- Debounce expensive operations
+
+### Memory Usage
+
+- Event handlers cleaned up on component unmount
+- Activity feeds automatically limited
+- No event history stored beyond UI needs
+- Connection stats updated incrementally

+# SSE to WebSocket Migration Guide
+
+**Status:** Migration Complete  
+**Date:** November 2025
+
+## Overview
+
+This guide documents the migration from Server-Sent Events (SSE) to WebSocket for real-time updates in PurposePath.
+
+---
+
+## Migration Summary
+
+| Aspect | SSE (Old) | WebSocket (New) |
+|--------|-----------|-----------------|
+| **Connection** | Unidirectional (server → client) | Bidirectional |
+| **Protocol** | HTTP | WS/WSS |
+| **Authentication** | Header-based | Post-connection message |
+| **Reconnection** | Automatic by browser | Custom with exponential backoff |
+| **Keep-alive** | Server-sent comments | Client ping every 8 min |
+| **Event Format** | Text-based SSE | JSON WebSocket messages |
+| **Connection Sharing** | One per tab | Shared across app |
+
+---
+
+## What Changed
+
+### 1. Connection Management
+
+**Old (SSE):**
+```typescript
+// Multiple EventSource connections
+const eventSource = new EventSource('/api/events');
+event Source.addEventListener('message', handler);
+```
+
+**New (WebSocket):**
+```typescript
+// Single WebSocket connection managed by RealtimeContext
+import { useRealtimeEvent } from '../hooks/realtime';
+
+useRealtimeEvent({
+  eventType: 'goal.created',
+  onEvent: (message) => { /* handler */ }
+});
+```
+
+### 2. Authentication
+
+**Old (SSE):**
+- Token passed in URL query parameter
+- Authentication on connection
+
+**New (WebSocket):**
+- Token sent in post-connection auth message
+- Server validates and responds with `auth.success` or `auth.error`
+
+### 3. Event Structure
+
+**Old (SSE):**
+```
+event: goal-created
+data: {"id": "123", "title": "New Goal"}
+```
+
+**New (WebSocket):**
+```json
+{
+  "type": "goal.created",
+  "data": {
+    "goalId": "123",
+    "title": "New Goal",
+    "tenantId": "tenant-1",
+    "createdAt": "2025-11-03T12:00:00Z"
+  },
+  "timestamp": "2025-11-03T12:00:00Z",
+  "eventId": "evt_abc123",
+  "tenantId": "tenant-1"
+}
+```
+
+### 4. Event Naming
+
+| SSE Event | WebSocket Event |
+|-----------|-----------------|
+| `goal-created` | `goal.created` |
+| `goal-updated` | Multiple specific events (`goal.activated`, `goal.completed`, etc.) |
+| `action-created` | `action.created` |
+| `issue-created` | `issue.created` |
+
+### 5. React Integration
+
+**Old (SSE):**
+```typescript
+// Manual subscription management
+useEffect(() => {
+  const es = new EventSource('/api/events');
+  es.addEventListener('goal-created', handler);
+  return () => es.close();
+}, []);
+```
+
+**New (WebSocket):**
+```typescript
+// Automatic subscription cleanup
+useRealtimeEvent({
+  eventType: 'goal.created',
+  onEvent: handler
+});
+```
+
+---
+
+## Breaking Changes
+
+### 1. Event Type Names
+
+**Impact:** Code that references event types
+
+**Action Required:**
+- Replace hyphenated event names with dot notation
+- Update event type strings in code
+- Use `EventTypes` constants from `types/realtime.ts`
+
+**Example:**
+```typescript
+// ❌ Old
+eventSource.addEventListener('goal-created', handler);
+
+// ✅ New
+useRealtimeEvent({
+  eventType: 'goal.created',  // or EventTypes.GOAL_CREATED
+  onEvent: handler
+});
+```
+
+### 2. Event Data Structure
+
+**Impact:** Code that accesses event data properties
+
+**Action Required:**
+- Update property access to use new structure
+- All fields are camelCase
+- Wrapped in `message.data`
+
+**Example:**
+```typescript
+// ❌ Old
+function handler(event) {
+  const goalId = event.data.goal_id;
+}
+
+// ✅ New
+function handler(message) {
+  const goalId = message.data.goalId;  // camelCase
+}
+```
+
+### 3. Connection Management
+
+**Impact:** Custom connection handling code
+
+**Action Required:**
+- Remove manual EventSource creation
+- Use RealtimeContext instead
+- Let framework handle reconnection
+
+**Example:**
+```typescript
+// ❌ Old - Manual management
+const [eventSource, setEventSource] = useState(null);
+
+useEffect(() => {
+  const es = new EventSource('/api/events');
+  setEventSource(es);
+  return () => es.close();
+}, []);
+
+// ✅ New - Managed by context
+// Just use hooks, context handles connection
+useRealtimeEvent({ eventType: 'goal.created', onEvent: handler });
+```
+
+---
+
+## Migration Steps
+
+### Step 1: Update Environment Variables
+
+Add WebSocket configuration:
+
+```bash
+# .env.development
+REACT_APP_FEATURE_REALTIME=true
+REACT_APP_REALTIME_WS_URL=wss://api.dev.purposepath.app/realtime
+
+# .env.production
+REACT_APP_FEATURE_REALTIME=true
+REACT_APP_REALTIME_WS_URL=wss://api.purposepath.app/realtime
+```
+
+### Step 2: Remove Old SSE Code
+
+**Files to remove/deprecate:**
+- `src/services/realtime.ts` (old SSE implementation)
+- `scripts/mock-sse-server.js` (old mock server)
+- Any custom EventSource wrappers
+
+### Step 3: Update Component Subscriptions
+
+Replace SSE subscriptions with WebSocket hooks:
+
+```typescript
+// Before
+useEffect(() => {
+  const es = new EventSource('/api/realtime/events');
+  
+  es.addEventListener('goal-created', (event) => {
+    const data = JSON.parse(event.data);
+    handleGoalCreated(data);
+  });
+  
+  return () => es.close();
+}, []);
+
+// After
+useRealtimeEvent({
+  eventType: 'goal.created',
+  onEvent: (message) => {
+    handleGoalCreated(message.data);
+  }
+});
+```
+
+### Step 4: Update Event Handlers
+
+Update handlers to use new data structure:
+
+```typescript
+// Before
+function handleGoalCreated(data) {
+  console.log('Goal:', data.goal_id, data.goal_title);
+}
+
+// After
+function handleGoalCreated(data) {
+  console.log('Goal:', data.goalId, data.title);
+}
+```
+
+### Step 5: Test Migration
+
+1. Enable WebSocket feature flag
+2. Verify connection indicator shows "Connected"
+3. Test each event type:
+   - Create goal → verify toast notification
+   - Complete goal → verify UI update
+   - Create action → verify dashboard update
+4. Test reconnection (disable network, re-enable)
+5. Test multiple tabs (connection sharing)
+
+---
+
+## Deprecated Code
+
+### Files Marked for Removal
+
+These files are no longer used and can be removed:
+
+| File | Status | Replacement |
+|------|--------|-------------|
+| `src/services/realtime.ts` | Deprecated | `src/services/realtime-websocket.ts` |
+| `scripts/mock-sse-server.js` | Deprecated | `scripts/mock-ws-server.js` |
+| Old event handlers in components | To migrate | Use hooks from `src/hooks/realtime.ts` |
+
+### Removal Timeline
+
+- **Phase 1 (Current):** Both systems operational, WebSocket is default
+- **Phase 2 (2 weeks):** Monitor WebSocket stability
+- **Phase 3 (4 weeks):** Remove SSE feature flag
+- **Phase 4 (6 weeks):** Delete deprecated SSE code
+
+---
+
+## Compatibility
+
+### Browser Support
+
+WebSocket is supported in:
+- ✅ Chrome 16+
+- ✅ Firefox 11+
+- ✅ Safari 7+
+- ✅ Edge (all versions)
+- ✅ Mobile browsers (iOS Safari 7+, Chrome Mobile)
+
+**Result:** Better compatibility than SSE (which had issues in some browsers)
+
+### Backend Compatibility
+
+WebSocket backend must support:
+- AWS API Gateway WebSocket API
+- Post-connection authentication
+- Event broadcasting to connections
+- Connection lifecycle management
+
+---
+
+## Rollback Plan
+
+If critical issues arise:
+
+### 1. Quick Rollback (Feature Flag)
+
+```bash
+# Disable WebSocket
+REACT_APP_FEATURE_REALTIME=false
+```
+
+This disables all WebSocket features. Components gracefully degrade to periodic polling if implemented.
+
+### 2. Full Rollback (Code)
+
+If needed to revert to SSE:
+
+1. Revert to previous Git tag
+2. Redeploy frontend
+3. Keep SSE backend endpoints active
+4. Monitor for 24 hours
+
+**Rollback Command:**
+```bash
+git revert <websocket-merge-commit>
+git push origin main
+```
+
+---

+
+## Troubleshooting Migration Issues
+
+### Issue: Events not being received
+
+**Possible Causes:**
+1. Feature flag not enabled
+2. WebSocket URL incorrect
+3. Authentication failing
+4. Backend not broadcasting events
+
+**Solutions:**
+1. Check `REACT_APP_FEATURE_REALTIME=true`
+2. Verify `REACT_APP_REALTIME_WS_URL`
+3. Check browser console for auth errors
+4. Verify backend WebSocket implementation
+
+### Issue: Old event names still in code
+
+**Solution:**
+Search codebase for old patterns:
+
+```bash
+# Find hyphenated event names
+grep -r "goal-created" src/
+grep -r "action-updated" src/
+
+# Find snake_case properties
+grep -r "goal_id" src/
+grep -r "user_id" src/
+```
+
+Replace with new conventions.
+
+### Issue: Duplicate events
+
+**Cause:** Both SSE and WebSocket active
+
+**Solution:**
+Ensure old SSE code is completely removed or feature flagged off.

+7. [Complete Examples](#7-complete-examples)
+
+---
+
+## 1. Message Envelope Format
+
+All WebSocket messages from backend to frontend follow this **exact structure**:
+
+```typescript
+interface WebSocketMessage<T = any> {
+  type: string;        // Event type identifier (e.g., "goal.created", "action.completed")
+  timestamp: string;   // ISO 8601 UTC timestamp (e.g., "2025-11-03T14:30:00Z")
+  data: T;            // Event-specific payload (structure varies by event type)
+}
+```
+
+### Example Message:
+
+```json
+{
+  "type": "goal.created",
+  "timestamp": "2025-11-03T14:30:00.000Z",
+  "data": {
+    "goalId": "550e8400-e29b-41d4-a716-446655440000",
+    "tenantId": "tenant-123",
+    "userId": "user-456",
+    "title": "Increase Revenue by 20%",
+    "description": "Focus on enterprise customers",
+    "status": "draft",
+    "createdAt": "2025-11-03T14:30:00.000Z",
+    "createdBy": "user-456"
+  }
+}
+```
+
+### Key Points:
+
+- **`type`**: Always a string, always present, uses dot notation (e.g., `goal.created`, `measure.reading_created`)
+- **`timestamp`**: Always ISO 8601 UTC format, millisecond precision
+- **`data`**: Always an object (never null), structure depends on event type
+- **No additional envelope fields**: No `version`, `id`, or `source` fields
+
+---
+
+## 2. Field Naming Convention
+
+### ✅ ALL payloads use **camelCase** (NOT snake_case)
+
+```typescript
+// ✅ CORRECT (What you'll actually receive)
+{
+  "goalId": "123",
+  "tenantId": "tenant-456",
+  "userId": "user-789",
+  "createdAt": "2025-11-03T14:30:00Z",
+  "updatedBy": "user-111"
+}
+
+// ❌ WRONG (You will NOT see this format)
+{
+  "goal_id": "123",           // ❌ Never snake_case
+  "tenant_id": "tenant-456",  // ❌ Never snake_case
+  "user_id": "user-789"       // ❌ Never snake_case
+}
+```
+
+### Field Name Examples:
+
+| Entity | Field Names (camelCase) |
+|--------|-------------------------|
+| **IDs** | `goalId`, `measureId`, `actionId`, `issueId`, `tenantId`, `userId` |
+| **Timestamps** | `createdAt`, `updatedAt`, `deletedAt`, `completedAt`, `pausedAt` |
+| **Actions** | `createdBy`, `updatedBy`, `deletedBy`, `completedBy`, `assignedTo` |
+| **Nested** | `targetDate`, `targetValue`, `currentValue`, `dueDate`, `achievementRate` |
+
+---

+}
+```
+
+---
+
+## 4. System Events
+
+### 4.1 Ping/Pong (Keep-Alive)
+
+**Backend does NOT send ping messages**. AWS API Gateway WebSocket handles connection keep-alive automatically.
+
+**Client responsibility**: None required for keep-alive.
+
+**What happens if client doesn't respond**: N/A - no ping/pong protocol implemented.
+
+**Connection timeout**: Connections automatically close after **10 minutes of inactivity** (AWS API Gateway default).
+
+**Recommendation**: Send a periodic message from client every 8-9 minutes if no user activity to keep connection alive:
+
+```typescript
+// Send keep-alive every 8 minutes
+setInterval(() => {
+  if (ws.readyState === WebSocket.OPEN) {
+    ws.send(JSON.stringify({ action: 'ping' }));
+  }
+}, 8 * 60 * 1000);
+```
+
+---
+
+### 4.2 Error Events
+
+#### Error Format:
+
+```typescript
+{
+  type: string;                // Event type + ".error" suffix
+  timestamp: string;
+  data: {
+    error: string;             // Human-readable error message
+    code: string;              // Machine-readable error code
+  }
+}
+```
+
+#### Error Codes:
+
+| Code | Description | HTTP Status | Client Action |
+|------|-------------|-------------|---------------|
+| `UNAUTHORIZED` | Invalid or expired token | 401 | Refresh token, reconnect |
+| `FORBIDDEN` | User lacks permission | 403 | Show error, don't retry |
+| `NOT_FOUND` | Resource doesn't exist | 404 | Remove from UI |
+| `VALIDATION_ERROR` | Invalid request data | 422 | Show validation errors |
+| `RATE_LIMIT_EXCEEDED` | Too many requests | 429 | Backoff, retry after delay |
+| `INTERNAL_ERROR` | Server-side error | 500 | Show error, retry |
+
+#### Error Example - Unauthorized:
+
+```json
+{
+  "type": "connection.error",
+  "timestamp": "2025-11-03T14:35:00.000Z",
+  "data": {
+    "error": "Authentication token expired",
+    "code": "UNAUTHORIZED"
+  }
+}
+```
+
+**Client action on UNAUTHORIZED**:
+1. Close WebSocket connection
+2. Refresh authentication token via `POST /auth/refresh`
+3. Reconnect with new token
+
+#### Error Example - Rate Limit:
+
+```json
+{
+  "type": "broadcast.error",
+  "timestamp": "2025-11-03T14:40:00.000Z",
+  "data": {
+    "error": "Too many requests, please slow down",
+    "code": "RATE_LIMIT_EXCEEDED"
+  }
+}
+```
+
+**Client action on RATE_LIMIT_EXCEEDED**:
+1. Implement exponential backoff
+2. Wait 1s, 2s, 4s, 8s between retries
+3. Show user-friendly message
+
+---
+
+## 5. Connection & Authentication
+
+### 5.1 WebSocket URL Format
+
+```
+wss://api.{env}.purposepath.app/realtime
+```
+
+**Environments**:
+- **Development**: `wss://api.dev.purposepath.app/realtime`
+- **Staging**: `wss://api.staging.purposepath.app/realtime`
+- **Production**: `wss://api.purposepath.app/realtime`
+
+**❌ IMPORTANT**: Do NOT include query parameters in URL (no `?access_token=...` or `?tenant=...`)
+
+### 5.2 Connection Flow
+
+```typescript
+// 1. Establish WebSocket connection
+const ws = new WebSocket('wss://api.dev.purposepath.app/realtime');
+
+// 2. Wait for connection to open
+ws.onopen = () => {
+  console.log('WebSocket connected');
+  
+  // 3. Send authentication message
+  const token = localStorage.getItem('authToken');
+  ws.send(JSON.stringify({
+    action: 'auth',
+    token: token
+  }));
+};
+
+// 4. Receive authentication response
+ws.onmessage = (event) => {
+  const message = JSON.parse(event.data);
+  
+  if (message.type === 'auth.success') {
+    console.log('Authenticated successfully');
+    // Connection is ready for events
+  } else if (message.type === 'auth.error') {
+    console.error('Authentication failed:', message.data.error);
+    // Handle authentication failure
+  }
+};
+```
+
+### 5.3 Authentication Response
+
+**Success**:
+```json
+{
+  "type": "auth.success",
+  "timestamp": "2025-11-03T14:30:00.000Z",
+  "data": {
+    "tenantId": "tenant-123",
+    "userId": "user-456",
+    "connectionId": "conn-abc123"
+  }
+}
+```
+
+**Failure**:
+```json
+{
+  "type": "auth.error",
+  "timestamp": "2025-11-03T14:30:00.000Z",
+  "data": {
+    "error": "Invalid authentication token",
+    "code": "UNAUTHORIZED"
+  }
+}
+```
+
+### 5.4 Token Expiration
+
+**What happens**:
+1. Backend detects expired token
+2. Sends `UNAUTHORIZED` error
+3. Closes WebSocket connection
+
+**Client should**:
+1. Listen for `UNAUTHORIZED` error
+2. Refresh auth token via `POST /auth/refresh`
+3. Reconnect with new token
+
+**Example**:
+```typescript
+ws.onmessage = (event) => {
+  const message = JSON.parse(event.data);
+  
+  if (message.data?.code === 'UNAUTHORIZED') {
+    // Token expired, refresh and reconnect
+    refreshAuthToken().then(newToken => {
+      localStorage.setItem('authToken', newToken);
+      reconnect();
+    });
+  }
+};
+```
+
+---
+
+## 6. Event History on Reconnect
+
+### 6.1 Current Behavior
+
+**Backend does NOT support `lastEventId` for missed events.**
+
+When client reconnects:
+- ❌ No replay of missed events
+- ❌ No event history buffer
+- ✅ Client continues receiving NEW events from reconnection time forward
+
+### 6.2 Client Recommendation
+
+**Option 1: Optimistic UI + REST API Sync**
+```typescript
+ws.onopen = async () => {
+  // After reconnect, fetch latest data via REST API
+  await fetchLatestGoals();
+  await fetchLatestActions();
+  
+  // Then continue with real-time updates
+  console.log('Synced with latest data');
+};
+```
+
+**Option 2: Track Last Sync Time**
+```typescript
+let lastSyncTime = new Date().toISOString();
+
+ws.onmessage = (event) => {
+  const message = JSON.parse(event.data);
+  lastSyncTime = message.timestamp;
+  handleEvent(message);
+};
+
+ws.onopen = async () => {
+  // Fetch events since last sync
+  await fetchEventsSince(lastSyncTime);
+};
+```
+
+**Option 3: Full Reload on Reconnect**
+```typescript
+ws.onopen = async () => {
+  // Simple approach: reload entire page
+  window.location.reload();
+};
+```
+
+### 6.3 Future Enhancement (Roadmap)
+
+Backend team is planning to add:
+- Event buffer (last 100 events per tenant)
+- `lastEventId` support for replay
+- Event sequence numbers
+
+**Not available yet** - use REST API sync for now.
+

+
+## 7. Complete Examples
+
+### Example 1: Goal Creation Flow
+
+**User Action**: User clicks "Create Goal" button and submits form
+
+**REST API Call**:
+```http
+POST /api/goals
+Content-Type: application/json
+Authorization: Bearer {token}
+X-Tenant-Id: tenant-123
+
+{
+  "title": "Increase Revenue by 20%",
+  "description": "Focus on enterprise customers"
+}
+```
+
+**REST API Response** (immediate):
+```json
+{
+  "id": "550e8400-e29b-41d4-a716-446655440000",
+  "tenantId": "tenant-123",
+  "userId": "user-456",
+  "title": "Increase Revenue by 20%",
+  "description": "Focus on enterprise customers",
+  "status": "draft",
+  "createdAt": "2025-11-03T14:30:00.000Z",
+  "createdBy": "user-456"
+}
+```
+
+**WebSocket Event** (within 500ms):
+```json
+{
+  "type": "goal.created",
+  "timestamp": "2025-11-03T14:30:00.000Z",
+  "data": {
+    "goalId": "550e8400-e29b-41d4-a716-446655440000",
+    "tenantId": "tenant-123",
+    "userId": "user-456",
+    "title": "Increase Revenue by 20%",
+    "description": "Focus on enterprise customers",
+    "status": "draft",
+    "createdAt": "2025-11-03T14:30:00.000Z",
+    "createdBy": "user-456"
+  }
+}
+```
+
+**Frontend Behavior**:
+1. Optimistic UI update on REST response
+2. WebSocket event received by **all connected clients** in same tenant
+3. Other users see new goal appear in real-time
+4. Creator sees confirmation (event validates optimistic update)
+
+---
+
+### Example 2: Action Status Change
+
+**User Action**: User marks action as "In Progress"
+
+**REST API Call**:
+```http
+PATCH /api/operations/actions/action-555
+Content-Type: application/json
+Authorization: Bearer {token}
+X-Tenant-Id: tenant-123
+
+{
+  "status": "in_progress"
+}
+```
+
+**WebSocket Event**:
+```json
+{
+  "type": "action.status_changed",
+  "timestamp": "2025-11-03T15:20:00.000Z",
+  "data": {
+    "actionId": "action-555",
+    "tenantId": "tenant-123",
+    "previousStatus": "todo",
+    "newStatus": "in_progress",
+    "changedAt": "2025-11-03T15:20:00.000Z",
+    "changedBy": "user-789"
+  }
+}
+```
+
+**Frontend Behavior**:
+1. Update action status badge
+2. Move card to "In Progress" column (if Kanban board)
+3. Show user avatar on action card
+4. Notify assignee (if different from actor)
+
+---
+
+### Example 3: Measure Reading with Chart Update
+
+**User Action**: User records new Measure value
+
+**REST API Call**:
+```http
+POST /api/measures/measure-111/readings
+Content-Type: application/json
+Authorization: Bearer {token}
+X-Tenant-Id: tenant-123
+
+{
+  "value": 125000,
+  "date": "2025-11-03",
+  "note": "Q4 projection on track"
+}
+```
+
+**WebSocket Event**:
+```json
+{
+  "type": "measure.reading.created",
+  "timestamp": "2025-11-03T16:30:00.000Z",
+  "data": {
+    "readingId": "reading-333",
+    "measureId": "measure-111",
+    "tenantId": "tenant-123",
+    "value": 125000,
+    "date": "2025-11-03",
+    "note": "Q4 projection on track",
+    "recordedAt": "2025-11-03T16:30:00.000Z",
+    "recordedBy": "user-456",
+    "progress": 25.0
+  }
+}
+```
+
+**Frontend Behavior**:
+1. Add data point to chart (Chart.js/Recharts)
+2. Update progress bar (25%)
+3. Animate chart transition
+4. Show notification: "Measure updated: 25% complete"

+# WebSocket Migration Analysis & Implementation Plan
+
+**Date:** October 5, 2025  
+**Project:** PurposePath_Web  
+**Purpose:** Migrate from SSE to WebSocket-based real-time updates
+
+---
+
+## Executive Summary
+
+The PurposePath frontend currently has **partial SSE (Server-Sent Events) infrastructure** in place (`src/services/realtime.ts`) that only supports **goal activity updates**. The backend is now implementing **WebSocket-based real-time updates** using AWS API Gateway WebSocket API. This document analyzes the existing implementation and provides a comprehensive migration and expansion plan.
+
+### Key Findings
+
+✅ **Existing Infrastructure:**
+- SSE-based goal activity subscription (`subscribeToGoalActivity`)
+- Feature flag support (`REACT_APP_FEATURE_REALTIME`)
+- SSE base URL override (`REACT_APP_SSE_BASE_URL`)
+- Event normalization logic for activities, decisions, attachments
+- Mock SSE server for local testing
+
+❌ **What's Missing:**
+- **No WebSocket implementation** (only SSE with EventSource)
+- **No global real-time connection manager**
+- **No support for action, Measure, or issue events**
+- **No reconnection logic** (EventSource auto-reconnects but limited control)
+- **No connection state management**
+- **No event handlers for most backend event types**
+- **No integration with state management contexts**
+- **No UI indicators for real-time connection status**
+
+🎯 **Migration Strategy:**
+- **Replace** `EventSource` with `WebSocket`
+- **Expand** from goal-only to all entity types
+- **Integrate** with existing Context API state management
+- **Add** comprehensive reconnection and error handling
+- **Preserve** existing feature flag and configuration patterns
+
+---
+
+## 1. Analysis: Existing Real-time Infrastructure
+
+### 1.1 Current Implementation (`src/services/realtime.ts`)
+
+**Features:**
+- ✅ Feature flag check (`isRealtimeEnabled()`)
+- ✅ SSE-based connection (`EventSource`)
+- ✅ Goal activity subscription (`subscribeToGoalActivity`)
+- ✅ Event normalization (activities, decisions, attachments)
+- ✅ Token and tenant ID passing via query params
+- ✅ Exponential backoff reconnection (via EventSource `onerror`)
+- ✅ Status callbacks (`connecting`, `open`, `closed`, `error`, `reconnecting`)
+
+**Limitations:**
+- ❌ Only supports **goal activity** events (not actions, Measures, issues)
+- ❌ Uses **EventSource** (SSE) instead of WebSocket
+- ❌ No support for tenant-wide subscriptions
+- ❌ No ping/pong heartbeat handling
+- ❌ No connection lifecycle management (singleton/shared connection)
+- ❌ No integration with global state (Context API)
+- ❌ Limited event type coverage
+
+**Current Event Types Supported:**
+```typescript
+// Current (Goal Activity Only)
+- activity.created
+- decision.created
+- attachment.created
+- measure.reading.created (mentioned but not in backend spec)
+```
+
+**Backend WebSocket Event Types (from spec):**
+```typescript
+// Goal Events
+- goal.created
+- goal.activated
+- goal.completed
+- goal.cancelled
+- goal.activity.created
+
+// Action Events
+- action.created
+- action.status_changed
+- action.completed
+- action.priority_changed
+- action.reassigned
+- action.progress_updated
+
+// Measure Events
+- measure.reading.created
+
+// Issue Events
+- issue.created
+- issue.status_changed
+
+// Decision Events
+- decision.created
+
+// Attachment Events
+- attachment.created
+
+// System Events
+- ping (respond with pong)
+- error
+```
+
+### 1.2 State Management Architecture
+
+**Pattern:** Context API (React Context)
+
+**Existing Contexts:**
+- `AuthContext` - User, tenant, tokens
+- `FeaturesContext` - Feature flags (includes `realtime: boolean`)
+- `LimitsContext` - Usage limits
+- `SubscriptionContext` - Subscription tier and billing
+- `PlanningContext` - Planning periods and time horizons
+
+**Entity State Management:**
+- ❌ **No global Goal context** (components load goals individually via `listGoals()`)
+- ❌ **No global Action context** (loaded per component)
+- ❌ **No global Issue context** (loaded per component)
+- ❌ **No global Measure context** (loaded per component)
+- ✅ Uses service layer for data fetching (`src/services/`)
+
+**Current Pattern:**
+```typescript
+// Components load their own data
+const [goals, setGoals] = useState<Goal[]>([]);
+
+useEffect(() => {
+  const loadData = async () => {
+    const response = await listGoals();
+    setGoals(response.data);
+  };
+  loadData();
+}, []);
+```
+
+**Issue:** No centralized state means real-time updates need to be applied at each component level OR we need a global state solution.
+
+### 1.3 Authentication Integration
+
+**Token Storage:**
+```typescript
+// src/contexts/AuthContext.tsx
+- accessToken: localStorage (via apiClient.setToken())
+- refreshToken: localStorage (key: 'refreshToken')
+- tenantId: localStorage (key: 'tenantId')
+```
+
+**Token Refresh:**
+```typescript
+// src/services/api.ts
+- 401 interceptor calls /auth/refresh
+- Sends { refresh_token } (snake_case)
+- Updates tokens in localStorage
+```
+
+**Perfect for WebSocket:**
+- ✅ Tokens are globally accessible
+- ✅ Refresh mechanism already exists
+- ✅ Tenant ID is stored and managed
+
+### 1.4 Environment Configuration
+
+**Existing Variables:**
+```bash
+# env.example
+REACT_APP_FEATURE_REALTIME=false  # Feature flag
+REACT_APP_SSE_BASE_URL=           # SSE URL override (for mock server)
+
+# Service URLs
+REACT_APP_ACCOUNT_API_URL=https://api.dev.purposepath.app/account/api/v1
+REACT_APP_COACHING_API_URL=https://api.dev.purposepath.app/coaching/api/v1
+REACT_APP_TRACTION_API_URL=https://api.dev.purposepath.app/traction/api/v1
+```
+
+**Needed for WebSocket:**
+```bash
+REACT_APP_REALTIME_WS_URL=wss://api.dev.purposepath.app/realtime
+```
+
+### 1.5 Dependencies Audit
+
+**Current Dependencies:**
+```json
+// package.json
+{
+  "axios": "^1.6.2",           // HTTP client
+  "sonner": "^1.2.4",          // Toast notifications
+  "react-router-dom": "^6.8.1" // Routing
+}
+```
+
+**WebSocket-related (dev dependencies only):**
+- `faye-websocket` (via webpack dev server)
+- `websocket-driver` (via webpack dev server)
+
+**❌ Missing:**
+- No `reconnecting-websocket` library
+- No WebSocket client library for production
+- No event emitter library (e.g., `mitt`, `eventemitter3`)
+
+**Recommendation:**
+- ✅ Use native `WebSocket` API (browser built-in)
+- ✅ Implement custom reconnection logic (already exists in SSE version)
+- ✅ Use React hooks for event handling (no extra library needed)
+
+### 1.6 TypeScript Types
+
+**Existing Types (`src/types/strategic-planning.ts`):**
+```typescript
+✅ Goal, GoalStatus, GoalMeasure
+✅ Action, ActionStatus, ActionPriority
+✅ Issue, IssueStatus, IssueImpact
+✅ SharedMeasure, TimeHorizon, MeasureReading
+✅ Strategy, Decision
+```
+
+**Missing Types:**
+- ❌ WebSocket message envelope types
+- ❌ Real-time event payload types
+- ❌ Connection state types
+- ❌ Event handler types
+
+---
+

+
+### 3.2 React Context Integration
+
+```typescript
+// src/contexts/RealtimeContext.tsx
+
+import React, { createContext, useContext, useEffect, useState } from 'react';
+import { RealtimeWebSocket } from '../services/realtime-websocket';
+import { apiClient } from '../services/api';
+
+interface RealtimeContextValue {
+  connection: RealtimeWebSocket | null;
+  status: ConnectionStatus;
+  isEnabled: boolean;
+}
+
+const RealtimeContext = createContext<RealtimeContextValue | null>(null);
+
+export const RealtimeProvider: React.FC<{ children: React.ReactNode }> = ({ children }) => {
+  const [connection, setConnection] = useState<RealtimeWebSocket | null>(null);
+  const [status, setStatus] = useState<ConnectionStatus>('disconnected');
+  const isEnabled = useFeatures().realtime;
+
+  useEffect(() => {
+    if (!isEnabled) return;
+
+    const ws = new RealtimeWebSocket(
+      () => apiClient.getToken(),
+      () => localStorage.getItem('tenantId'),
+      async () => {
+        await apiClient.refreshToken();
+      }
+    );
+
+    ws.onStatusChange(setStatus);
+    ws.connect();
+    setConnection(ws);
+
+    return () => {
+      ws.disconnect();
+    };
+  }, [isEnabled]);
+
+  return (
+    <RealtimeContext.Provider value={{ connection, status, isEnabled }}>
+      {children}
+    </RealtimeContext.Provider>
+  );
+};
+
+export const useRealtime = () => {
+  const context = useContext(RealtimeContext);
+  if (!context) throw new Error('useRealtime must be within RealtimeProvider');
+  return context;
+};
+
+export function useRealtimeEvent<T = any>(
+  eventType: string,
+  handler: (data: T) => void,
+  enabled = true
+) {
+  const { connection } = useRealtime();
+
+  useEffect(() => {
+    if (!connection || !enabled) return;
+    
+    connection.on(eventType, handler);
+    return () => connection.off(eventType, handler);
+  }, [connection, eventType, handler, enabled]);
+}
+```
+
+### 3.3 Usage Example
+
+```typescript
+// src/components/strategic-planning/GoalRoom.tsx
+
+export const GoalRoom: React.FC<{ goalId: string }> = ({ goalId }) => {
+  const [activities, setActivities] = useState<Activity[]>([]);
+
+  // Subscribe to goal activity events
+  useRealtimeEvent('goal.activity.created', (data) => {
+    if (data.goalId === goalId) {
+      setActivities(prev => [data.activity, ...prev]);
+      toast.success('New activity added');
+    }
+  });
+
+  // Subscribe to goal completion
+  useRealtimeEvent('goal.completed', (data) => {
+    if (data.goalId === goalId) {
+      toast.success('Goal completed! 🎉');
+    }
+  });
+
+  // ... rest of component
+};
+```
+
+---
+
+## 4. Migration Path: SSE → WebSocket
+
+### Step-by-Step Migration
+
+1. **Keep SSE as Fallback (Optional)**
+   - If needed, keep `realtime.ts` for backward compatibility
+   - Add WebSocket as primary, fallback to SSE if unavailable
+
+2. **Gradual Rollout**
+   - Phase 1: Deploy WebSocket backend
+   - Phase 2: Deploy WebSocket frontend (with feature flag)
+   - Phase 3: Enable for beta users
+   - Phase 4: Enable for all users
+   - Phase 5: Remove SSE code
+
+3. **Deprecation Timeline**
+   - Week 1-2: WebSocket implementation
+   - Week 3: Testing with beta users
+   - Week 4: Full rollout
+   - Week 5+: Monitor and remove SSE
+
+### Breaking Changes
+
+❌ **None** - WebSocket is a drop-in replacement for SSE at the API level.
+
+### Configuration Changes
+
+```bash
+# Old (SSE)
+REACT_APP_SSE_BASE_URL=http://localhost:5055
+
+# New (WebSocket)
+REACT_APP_REALTIME_WS_URL=ws://localhost:5055
+```
+
+---
+
+## 5. Risk Assessment & Mitigation
+
+| Risk | Impact | Probability | Mitigation |
+|------|--------|-------------|------------|
+| WebSocket connection fails | High | Low | Exponential backoff, graceful degradation |
+| Token expiration mid-connection | Medium | Medium | Detect UNAUTHORIZED, refresh, reconnect |
+| Duplicate events (race condition) | Low | Medium | Implement idempotency checks, de-dupe by ID |
+| High message volume (performance) | Medium | Low | Throttle/debounce UI updates, batch processing |
+| Browser compatibility | Low | Low | Use native WebSocket (supported in all modern browsers) |
+| Mock server doesn't match backend | Medium | High | Keep mock server in sync with backend spec |
+
+---
+
+## 6. Testing Strategy
+
+### Unit Tests
+
+- ✅ WebSocket connection lifecycle
+- ✅ Reconnection logic
+- ✅ Event normalization
+- ✅ Ping/pong handling
+- ✅ Error handling
+
+### Integration Tests
+

+- ✅ Component updates on events
+- ✅ Toast notifications
+
+### Manual Testing
+
+- ✅ Connect/disconnect/reconnect flows
+- ✅ Token expiration handling
+- ✅ Multiple tabs (connection sharing)
+- ✅ Network interruption recovery
+- ✅ Cross-browser testing
+
+---
+
+## 7. Timeline & Effort Estimate
+
+| Phase | Duration | Dependencies |
+|-------|----------|--------------|
+| Phase 1: Connection Manager | 2-3 days | Backend WebSocket API deployed |
+| Phase 2: Event Handling | 2 days | Phase 1 |
+| Phase 3: State Integration | 2-3 days | Phase 2 |
+| Phase 4: UI Integration | 1-2 days | Phase 3 |
+| Phase 5: Testing & Docs | 1-2 days | Phase 4 |
+| **Total** | **8-12 days** | - |
+
+---
+
+## 8. Success Criteria
+
+✅ **Functional:**
+- WebSocket connection establishes on login
+- Automatically reconnects on disconnect
+- All event types handled correctly
+- State updates in real-time
+- Token expiration handled gracefully
+
+✅ **Non-Functional:**
+- < 1s reconnection time (average)
+- < 100ms event-to-UI latency
+- 95%+ uptime (excluding backend issues)
+- No memory leaks
+- Works in all modern browsers
+
+✅ **User Experience:**
+- Connection status visible
+- Real-time updates feel instant
+- Toast notifications for important events
+- No duplicate/stale data
+
+---
+
+## 9. Recommended Next Steps
+
+1. **Review this analysis** with backend team to confirm WebSocket spec alignment
+2. **Approve migration approach** (Global Context vs. Component-Level)
+3. **Create tasks** in project management tool
+4. **Implement Phase 1** (Connection Manager)
+5. **Deploy backend WebSocket API** (if not already done)
+6. **Run parallel testing** with mock server
+7. **Beta rollout** to select users
+8. **Full deployment** with monitoring
+
+---
+
+## 10. Questions for Backend Team
+
+1. **WebSocket URL format confirmed?**
+   - `wss://api.{env}.purposepath.app/realtime?access_token={token}&tenant={tenantId}`
+
+2. **Ping/pong frequency?**
+   - How often does backend send `ping`?
+   - Is `pong` response required or optional?
+
+3. **Message envelope format confirmed?**
+   ```json
+   {
+     "type": "event_type",
+     "timestamp": "ISO8601",
+     "data": { ... }
+   }
+   ```
+
+4. **Error codes confirmed?**
+   - `UNAUTHORIZED` → refresh token
+   - `RATE_LIMIT_EXCEEDED` → backoff
+   - `INTERNAL_ERROR` → log and continue
+
+5. **Event payload structure confirmed?**
+   - Are payloads snake_case or camelCase?
+   - Do we need to normalize?
+
+6. **Connection limit per tenant?**
+   - Should we share one connection across tabs?
+   - Or allow multiple connections?
+
+7. **Event history on reconnect?**
+   - Does backend support `lastEventId` for missed events?
+   - Or do we just continue from current?

+# WebSocket Implementation - Quick Start for AI Agents
+
+**Purpose:** Quick reference for AI agents to resume work after chat session restart
+
+---
+
+## Current Status (As of October 5, 2025)
+
+**Phase:** 0 - Analysis & Planning ✅ **COMPLETE**  
+**Next Phase:** 1 - WebSocket Connection Manager (Not Started)  
+**Overall Progress:** 16% (1/6 phases)
+
+---
+
+## Critical Files to Read First
+
+1. **📊 Progress Tracker** (READ FIRST)
+   - `docs/WEBSOCKET_IMPLEMENTATION_PROGRESS.md`
+   - Contains detailed task breakdown, checkboxes, status
+
+2. **📖 Analysis Document**
+   - `docs/WEBSOCKET_MIGRATION_ANALYSIS.md`
+   - Contains architecture, technical specs, code examples
+
+3. **🔧 Existing Implementation**
+   - `src/services/realtime.ts` - Current SSE implementation (to be replaced)
+   - `src/contexts/AuthContext.tsx` - Token management (ready to use)
+   - `src/contexts/FeaturesContext.tsx` - Feature flags
+
+4. **📋 Backend Spec**
+   - `docs/backend-integration-specs-v2.md` - API contracts
+   - Look for "Real-time Endpoints (SSE)" section (will become WebSocket)
+
+---
+
+## Quick Context Summary
+
+### What We're Doing
+- **Migrating** from SSE (Server-Sent Events) to WebSocket for real-time updates
+- **Backend** is implementing AWS API Gateway WebSocket API
+- **Frontend** needs to replace EventSource with WebSocket and expand event coverage
+
+### What Exists
+- ✅ Partial SSE infrastructure (goal activity only)
+- ✅ Feature flag system (`REACT_APP_FEATURE_REALTIME`)
+- ✅ Auth with token storage, refresh, tenant ID
+- ✅ Context API state management pattern
+- ✅ TypeScript types for all entities
+- ✅ Mock SSE server for local testing
+
+### What's Missing
+- ❌ WebSocket implementation (only SSE)
+- ❌ Support for action, Measure, issue events
+- ❌ Global real-time state management
+- ❌ Connection status UI
+- ❌ Comprehensive event handlers
+
+---
+
+## Architecture Decision
+
+**Chosen Approach:** Global Context with React Hooks
+
+- Single WebSocket connection via `RealtimeContext`
+- React hooks for event subscription: `useRealtimeEvent()`
+- Follows existing Context API patterns
+- Better performance than component-level subscriptions
+
+---
+
+## Next Action (Phase 1)
+
+Create WebSocket connection manager:
+
+1. **Create** `src/services/realtime-websocket.ts`
+   - Implement `RealtimeWebSocket` class
+   - Connection lifecycle, reconnection, heartbeat
+   - See `WEBSOCKET_MIGRATION_ANALYSIS.md` section 3.1 for code
+
+2. **Create** `src/types/realtime.ts`
+   - All event payload types
+   - Connection status types
+
+3. **Update** `env.example`
+   - Add `REACT_APP_REALTIME_WS_URL`
+
+---
+
+## Backend WebSocket Spec (Quick Reference)
+
+**URL:** `wss://api.{env}.purposepath.app/realtime?access_token={token}&tenant={tenantId}`
+
+**Event Types:**
+- Goal: `goal.created`, `goal.activated`, `goal.completed`, `goal.cancelled`, `goal.activity.created`
+- Action: `action.created`, `action.status_changed`, `action.completed`, `action.priority_changed`, `action.reassigned`, `action.progress_updated`
+- Measure: `measure.reading.created`
+- Issue: `issue.created`, `issue.status_changed`
+- Decision: `decision.created`
+- Attachment: `attachment.created`
+- System: `ping` (respond with `pong`), `error`
+
+**Message Format:**
+```json
+{
+  "type": "event_type",
+  "timestamp": "ISO8601",
+  "data": { /* event-specific payload */ }
+}
+```
+
+**Error Codes:**
+- `UNAUTHORIZED` → refresh token, reconnect
+- `RATE_LIMIT_EXCEEDED` → backoff
+- `INTERNAL_ERROR` → log and continue
+
+---
+
+## Key Technical Decisions
+
+1. **Use native WebSocket API** (no external library needed)
+2. **Exponential backoff** for reconnection: 1s, 2s, 4s, 8s, 16s, 30s (max)
+3. **Token refresh** on UNAUTHORIZED via existing `apiClient.refreshToken()`
+4. **Event normalization** from snake_case to camelCase (keep from existing code)
+5. **Feature flag** controls connection: `REACT_APP_FEATURE_REALTIME`
+
+---
+
+## How to Resume Work
+
+1. **Read progress tracker**: `docs/WEBSOCKET_IMPLEMENTATION_PROGRESS.md`
+2. **Find current phase**: Check status table and task checkboxes
+3. **Review analysis**: `docs/WEBSOCKET_MIGRATION_ANALYSIS.md` for technical details
+4. **Create todo list**: Use `manage_todo_list` tool to track session tasks

+
+## Pattern: The Update Loop
+
+**Every time a task completes, this exact sequence happens:**
+
+```
+1. Complete the implementation (create/edit files)
+2. IMMEDIATELY update progress tracker:
+   - Mark checkbox complete
+   - Update phase progress %
+   - Update overall progress %
+   - Add change log entry
+   - Update timestamp
+3. Update session todo list
+4. Inform user with updated progress
+5. Move to next task
+```
+
+**This ensures:**
+- ✅ Documents always in sync
+- ✅ Progress always accurate
+- ✅ Session recovery always possible
+- ✅ User always informed
+- ✅ History captured in change log

+- `src/services/realtime-websocket.ts`
+- `src/types/realtime.ts`
+
+**Progress:**
+- Phase 1: 40% complete (2/5 tasks)
+- Overall: 23% complete
+
+**Documents Updated:**
+- ✅ Progress tracker (2 tasks checked, phase %, change log)
+- ✅ Session recovery (current state updated)
+- ✅ Session todo list (all current)
+
+**Next Session:**
+- Continue with Task 1.3: Update environment configuration
+- Then Task 1.4: Token refresh integration

+
+---
+
+## Key Takeaway
+
+**Every single task completion triggers a mandatory document update sequence.**
+
+This ensures that if the chat session ends at ANY point, the next session can:
+1. Read the progress docs
+2. See exactly what's done (checkboxes)
+3. See exactly what's next
+4. Continue seamlessly
+
+**No progress is ever lost!** 🔒

+   Add note: "Completed: [Date] [Time]"
+   Document: Any decisions, blockers, or deviations
+   ```
+
+3. **Update phase progress**
+   ```
+   Calculate: % complete for phase (completed tasks / total tasks)
+   Update: Phase status and progress percentage
+   Update: "Last Updated" date at top of document
+   ```
+
+4. **Add change log entry**
+   ```
+   Add entry to "Change Log" section:
+   "### [Date]
+   - **Task X.Y Complete**: [Brief description]
+   - **Files Created/Updated**: [List files]
+   - **Notes**: [Any important notes]"
+   ```
+
+### 🎯 After Completing a Phase
+
+1. **Update progress tracker**
+   ```
+   Change phase status: ⏳ Not Started → 🔄 In Progress → ✅ Complete
+   Add completion date
+   Update overall progress percentage
+   Calculate total time spent
+   ```
+
+2. **Update session recovery document**
+   ```
+   Update: docs/WEBSOCKET_SESSION_RECOVERY.md
+   Change: "Current Phase" and "Next Phase"
+   Update: "Overall Progress" percentage
+   Update: "Last Updated" date
+   ```
+
+3. **Create phase completion summary**
+   ```
+   Add to change log:
+   "### Phase X Complete - [Date]
+   - **Duration**: [X days/hours]
+   - **Deliverables**: [List files created]
+   - **Tests Added**: [List test files]
+   - **Issues Encountered**: [List any issues]

+## AI Agent Self-Check Protocol
+
+As an AI agent, I will follow this self-check protocol:
+
+### Before Each Response Involving Implementation
+
+1. **Check if task is complete in response**
+   - If YES → Update progress tracker BEFORE responding to user
+   - If NO → Note what will be done, update after completion
+
+2. **Verify documents are in sync**
+   - Read current progress tracker status
+   - Verify it matches actual work done
+   - If out of sync → Update immediately
+
+3. **Plan updates needed**
+   - Identify which documents need updates
+   - Use multi_replace_string_in_file for efficiency
+   - Update all relevant sections in one operation
+
+### After Each Implementation Step
+
+1. **Mandatory progress update**
+   ```typescript
+   // After creating file or completing task
+   await updateProgressTracker({
+     taskId: "1.2",
+     status: "complete",
+     note: "Created realtime-websocket.ts with full implementation"
+   });
+   ```
+
+2. **Verify update success**
+   - Check that checkbox changed
+   - Verify note was added
+   - Confirm date updated
+
+3. **Document in response**
+   - Tell user what was updated
+   - Show updated progress
+   - Highlight remaining tasks
+
+### Session Start Protocol
+
+1. **Read progress documents**
+   - WEBSOCKET_SESSION_RECOVERY.md (quick context)
+   - WEBSOCKET_IMPLEMENTATION_PROGRESS.md (detailed status)
+
+2. **Create session plan**
+   - Use manage_todo_list tool
+   - List tasks planned for session
+   - Mark first task in-progress
+
+3. **Inform user of status**
+   - Show current phase and progress
+   - Highlight next tasks
+   - Ask for confirmation to proceed
+
+---
+
+## Example Update Workflow
+
+### Scenario: Completing Task 1.1 (Create realtime-websocket.ts)
+
+**Step 1: Complete the work**
+```typescript
+// Create the file with implementation
+create_file({
+  filePath: "src/services/realtime-websocket.ts",
+  content: "/* WebSocket implementation */"
+});
+```
+
+**Step 2: Update progress tracker (REQUIRED)**
+```typescript
+multi_replace_string_in_file({
+  filePath: "docs/WEBSOCKET_IMPLEMENTATION_PROGRESS.md",
+  replacements: [
+    {
+      // Update task checkbox
+      oldString: "- [ ] **Task 1.1:** Create `src/services/realtime-websocket.ts`",
+      newString: "- [x] **Task 1.1:** Create `src/services/realtime-websocket.ts` ✅ Completed: Oct 5, 2025 14:30"
+    },
+    {
+      // Update Last Updated date
+      oldString: "**Last Updated:** October 5, 2025",
+      newString: "**Last Updated:** October 5, 2025 14:30"
+    },
+    {
+      // Add change log entry
+      oldString: "## Change Log\n\n### October 5, 2025",
+      newString: "## Change Log\n\n### October 5, 2025\n- **Task 1.1 Complete**: Created WebSocket connection manager\n- **Files Created**: `src/services/realtime-websocket.ts`\n- **Notes**: Implemented full lifecycle management with reconnection"
+    }
+  ]
+});
+```
+
+**Step 3: Update session todo list**
+```typescript
+manage_todo_list({
+  operation: "write",
+  todoList: [
+    { id: 1, title: "Create WebSocket manager", status: "completed" },
+    { id: 2, title: "Create TypeScript types", status: "in-progress" },
+    { id: 3, title: "Update env config", status: "not-started" }
+  ]
+});
+```
+
+**Step 4: Inform user**
+```markdown
+✅ **Task 1.1 Complete**: Created `src/services/realtime-websocket.ts`
+
+**Progress Updated:**
+- Progress tracker checkbox marked complete
+- Change log entry added
+- Session todo list updated
+
+**Phase 1 Progress:** 20% (1/5 subtasks complete)
+**Overall Progress:** 18% (phase 0 + 20% of phase 1)
+
+**Next:** Task 1.2 - Create TypeScript types (in progress)
+```
+
+---
+
+## Validation Checks
+
+Before marking a phase complete, verify:
+
+```
+□ All task checkboxes marked complete
+□ Phase status updated to ✅ Complete
+□ Completion date added
+□ Phase progress = 100%
+□ Overall progress % updated
+□ Change log has phase completion entry
+□ Session recovery doc updated
+□ All files mentioned in tasks exist
+□ All tests mentioned pass
+□ Documentation updated
+```
+
+---
+
+## Recovery from Missed Updates
+
+If documents fall out of sync:
+
+1. **Detect the issue**
+   - Compare actual files created vs. progress tracker
+   - Check for tasks marked complete but files don't exist
+   - Look for completed work not reflected in tracker
+
+2. **Reconcile immediately**
+   - Create reconciliation change log entry
+   - Update all missed checkboxes at once
+   - Add note explaining the gap
+   - Verify current state is accurate
+
+3. **Prevent recurrence**
+   - Follow mandatory update workflow strictly
+   - Use multi_replace for batch updates
+   - Always update before responding to user
+
+---
+
+## Tools for Updates
+
+### Use These Tools Consistently
+
+1. **manage_todo_list** - Session-level tracking
+   ```typescript
+   // Start of session
+   manage_todo_list({ operation: "write", todoList: [...] });
+   
+   // After each task
+   manage_todo_list({ operation: "write", todoList: [...] }); // Updated status
+   ```
+
+2. **multi_replace_string_in_file** - Batch document updates
+   ```typescript
+   // Update multiple sections at once
+   multi_replace_string_in_file({
+     explanation: "Update progress tracker after completing task 1.1",
+     replacements: [
+       { filePath, oldString, newString, explanation },
+       { filePath, oldString, newString, explanation },
+       // ... more updates
+     ]
+   });
+   ```
+
+3. **replace_string_in_file** - Single section updates
+   ```typescript
+   // For simple updates
+   replace_string_in_file({ filePath, oldString, newString });
+   ```
+
+---
+
+## Success Metrics
+
+Progress tracking is successful when:
+
+- ✅ Documents always reflect current state
+- ✅ No tasks marked complete without evidence (files, commits)
+- ✅ Change log has entry for every significant change
+- ✅ Session recovery doc always accurate for quick restart
+- ✅ Phase progress percentages accurate
+- ✅ User can see progress at a glance
+- ✅ Another AI agent can resume work seamlessly

+- Add change log entry"
+```
+
+---
+
+**Remember:** Progress tracking is not optional—it's mandatory for successful implementation and seamless session recovery!

+# Account API Specification
+
+**Version:** 2.4  
+**Last Updated:** January 28, 2026 (Username support in invitation activation + conflict error)  
+**Service Base URL:** `{REACT_APP_ACCOUNT_API_URL}` (e.g., `https://api.dev.purposepath.app/account/api/v1`)
+
+## Scope
+
+Consolidated account endpoints implemented by the Account Lambda controllers: `Auth`, `Users`, `Tenants`, `SubscriptionTiers`, `UserSubscription`, `Billing`, `Subscriptions`, `BillingWebhook`, `Health`.
+
+## Conventions
+
+- JSON uses camelCase. Legacy snake_case inputs remain backwards compatible only where noted (logout refresh token).
+- Response envelope (`ApiResponse<T>`): `{ "success": true|false, "data": {}, "message": "?", "error": "?", "code": "?" }`.
+- Paginated responses use `PaginatedResponse<T>`: same envelope plus `pagination: { page, limit, total, totalPages }`.
+- Authenticated endpoints require headers: `Authorization: Bearer {accessToken}`, `X-Tenant-Id: {tenantId}`. Public endpoints are marked.
+- Optional headers: `X-Frontend-Base-Url` (used for auth emails), `X-E2E-Test: true` (DEV only to bypass email verification on register).
+
+## JWT Claims (Issue #545)
+
+The access token JWT includes the following custom claims:
+- `user_id`: User's GUID
+- `tenant_id`: Tenant's GUID
+- `username`: User's username
+- `email_verified`: Boolean (from Person entity)
+- `user_status`: User status (e.g., "Active")
+- `role`: User role (e.g., "user" or "admin")
+- `is_tenant_owner`: Boolean - `true` if the user is the tenant owner, `false` otherwise (Issue #545)
+
+Frontend can decode the JWT to access these claims, but `isTenantOwner` is also available directly in `AuthResponse.user` for convenience.
+
+## Authentication
+
+### POST /auth/login
+- Body: `{ "username": "string", "password": "string" }` (username may be email-style; 3-50 chars).
+- Response `AuthResponse`:
+```json
+{
+  "success": true,
+  "data": {
+    "accessToken": "jwt",
+    "refreshToken": "jwt",
+    "user": {
+      "id": "uuid",
+      "email": "string",
+      "firstName": "string",
+      "lastName": "string",
+      "personId": "uuid|null",
+      "tenantId": "uuid",
+      "status": "string",
+      "isEmailVerified": true,
+      "isTenantOwner": false,
+      "createdAt": "2025-12-29T00:00:00Z",
+      "updatedAt": "2025-12-29T00:00:00Z"
+    },
+    "person": { "id": "uuid", "firstName": "string", "lastName": "string", "email": "string|null", "phone": "string|null", "title": "string|null" },
+    "tenant": { "id": "uuid", "name": "string", "status": "string" }
+  }
+}
+```
+- **Issue #545**: `user.isTenantOwner` is `true` if the authenticated user is the tenant owner (`tenant.ownerUserId == user.id`), `false` otherwise.
+- Errors: 401 invalid credentials, 403 `EMAIL_NOT_VERIFIED`.
+
+### POST /auth/google
+- Body: `{ "token": "string" }` (Google ID token from OAuth flow).
+- Response: same as login (includes `user.isTenantOwner`).
+- Notes: Validates token with Google, creates new user/tenant if external identity not found (new user is automatically the tenant owner), or logs in existing user. Auto-updates user avatar from Google profile if user has no avatar.
+- **Issue #546**: Allows registration even if Google doesn't provide email (person.email will be null, person.emailVerified will be false). Frontend can detect missing email and direct user to update it via PUT /user/email.
+
+### POST /auth/microsoft
+- Body: `{ "token": "string" }` (Microsoft ID token from OAuth/OIDC flow).
+- Response: same as login (includes `user.isTenantOwner`).
+- Notes: Validates token with Microsoft OIDC metadata endpoint, creates new user/tenant if external identity not found (new user is automatically the tenant owner), or logs in existing user. Auto-updates user avatar from Microsoft profile if user has no avatar.
+- **Issue #546**: Allows registration even if Microsoft doesn't provide email (person.email will be null, person.emailVerified will be false). Frontend can detect missing email and direct user to update it via PUT /user/email.
+
+### POST /auth/register
+- Body: `{ "username": "string", "email": "string", "password": "string", "firstName": "string", "lastName": "string", "phone": "string|null" }`.
+- DEV-only bypass: `X-E2E-Test: true` skips email verification.
+- Response: `AuthResponse` (auto-login path) or validation error. Email verification links use `X-Frontend-Base-Url` if provided.
+
+### POST /auth/forgot-password
+- Body: `{ "username": "string" }`.
+- Response: `{ "success": true, "message": "Password reset email sent" }`.
+- Notes: Password reset email is sent to the email address of the Person linked to the username.
+
+### POST /auth/reset-password
+- Body: `{ "token": "string", "newPassword": "string" }`.
+- Response: `{ "success": true, "message": "Password reset successfully" }`.
+
+### POST /auth/refresh
+- Body: `{ "refreshToken": "string" }`.
+- Response: `{ "success": true, "data": { "accessToken": "string", "refreshToken": "string" } }`.
+
+### POST /auth/confirm-email
+- Body: `{ "token": "string" }`.
+- Response: `{ "success": true, "message": "Email confirmed successfully" }`.
+
+### GET /auth/confirm-email/validate
+- Query: `token`.
+- Response: `{ "success": true, "data": { "status": "valid|used|expired|not_found|error" } }`.
+
+### POST /auth/resend-confirmation
+- Query: `username` (required - user's username); optional `X-Frontend-Base-Url` for link generation.
+- Response: `{ "success": true, "message": "Confirmation email resent" }`.
+- Notes: Always returns success even if username not found (security - prevents username enumeration). Email only sent if user exists and needs verification (status is Pending).
+
+### POST /auth/logout
+- Query: `refreshToken` (camelCase). Legacy `refresh_token` still accepted.
+- Response: `{ "success": true }`.
+
+### GET /auth/check-username (Public)
+**No Auth Required** - Check if a username is available for registration or invitation activation.
+
+- Query: `username` (string, required).
+- Response (Available):
+```json
+{
+  "success": true,
+  "data": {
+    "available": true,
+    "username": "johndoe"
+  }
+}
+```
+- Response (Not Available):
+```json
+{
+  "success": true,
+  "data": {
+    "available": false,
+    "username": "johndoe",
+    "message": "Username is already taken",
+    "reasonCode": "TAKEN"
+  }
+}
+```
+- Response (Invalid Format):
+```json
+{
+  "success": false,
+  "error": "Invalid username format",
+  "code": "VALIDATION_ERROR",
+  "details": {
+    "field": "username",
+    "message": "Username must be 3-50 characters, start with alphanumeric, and contain only alphanumeric, '.', '_', '-', '@'",
+    "reasonCode": "INVALID_FORMAT"
+  }
+}
+```
+- Reason Codes (data.reasonCode when `available: false`):
+  - `TAKEN`: Username is already in use.
+  - `RESERVED`: Username is a reserved system name (admin, support, system, etc.).
+  - `PREVIOUSLY_USED`: Username is reserved for 90 days after a change.
+  - `CHANGE_RATE_LIMITED`: Authenticated user is within the 30‑day username change cooldown.
+- **Notes**: 
+  - This is a public endpoint (no authentication required) for use during registration and invitation activation.
+  - Returns success with `available: false` for taken usernames (not an error state).
+  - Returns error only for invalid format or server errors.
+  - Reserved usernames (admin, support, system, etc.) are considered unavailable.
+  - If an authenticated user context is available, the response may return `CHANGE_RATE_LIMITED`.
+
+## Users (Single User Operations)
+
+### GET /user/{id}

+  "googleProfilePictureUrl": "https://...",
+  "username": "johndoe"
+}
+```
+- **Field Constraints:**
+  - `username` (optional): 3-50 characters, must start with alphanumeric, can contain alphanumeric + `.` `_` `-` `@`. Regex: `/^[a-zA-Z0-9][a-zA-Z0-9._@-]{2,49}$/`. When omitted, username is auto-generated from email (backward compatibility).
+  - `password` (password-based only): Required for password activation.

+- Username rules:
+  - 3-50 characters

+  }
+}
+```
+- **Note**: `tenant.name` is populated from the business foundation's company name if available, otherwise falls back to the tenant's name field.
+- **Email Verification** (Issue #619): When a user activates their account via invitation, their email is automatically marked as verified (`person.isEmailVerified = true`). The invitation acceptance itself serves as email validation, eliminating the need for a separate email verification step. The user's status is set to `Active` immediately upon successful activation.
+- Errors:
+  - 400 `VALIDATION_ERROR`: Invalid token/expired/already used/person already linked/email mismatch (OAuth)/invalid username format.
+  - 409 `USERNAME_NOT_AVAILABLE`: The specified username is already taken by another user (global uniqueness check).

+
+**Error Responses:**
+
+```json
+{
+  "success": false,
+  "error": "Username is already taken",
+  "code": "DUPLICATE_RESOURCE",
+  "details": {

+# Business Foundation API Specification
+
+**Version:** 1.0  
+**Status:** Verified Against Implementation  
+**Last Updated:** December 30, 2025  
+**Base URL:** `/business/foundation` and `/business/onboarding`
+
+---
+
+## Overview
+
+The Business Foundation API provides complete management of the six strategic pillars:
+
+1. **Business Profile** - Company facts, industry, stage, size
+2. **Core Identity** - Vision, purpose, core values
+3. **Target Market** - Niche statement, market size, ideal customer avatars (ICAs)
+4. **Products & Services** - Product/service catalog with full details
+5. **Value Proposition** - USP, key differentiators, competitive positioning
+6. **Business Model** - Revenue streams, pricing, partnerships, distribution
+
+The API implements 404 fallback pattern: When backend endpoints are not yet available, the frontend returns mock responses to allow UI development to proceed independently.
+
+---
+
+## Authentication & Headers
+
+All endpoints require:
+
+```
+Authorization: Bearer {accessToken}
+X-Tenant-Id: {tenantId}
+Content-Type: application/json

+
+---
+
+## Error Handling
+
+All error responses follow this format:
+
+```json
+{
+  "success": false,
+  "error": "string (error message)"
+}
+```
+
+**Common HTTP Status Codes:**
+- 400 - Bad Request (validation failed, malformed JSON)
+- 401 - Unauthorized (missing/invalid token)
+- 403 - Forbidden (invalid tenant, insufficient permissions)
+- 404 - Not Found (endpoint not yet implemented, triggers fallback)
+- 422 - Unprocessable Entity (semantic validation failed)
+- 500 - Internal Server Error
+
+**Client Handling:**
+- Always check `success` field in response
+- On 404, frontend uses mock fallback response
+- On 401, refresh token or redirect to login
+- On 4xx client errors, display user-friendly error message
+- On 500, retry with exponential backoff or display error
+
+---
+
+## Implementation Notes
+
+### Fallback Pattern
+When backend endpoints return 404, the frontend returns mock responses:
+- Generated IDs use format: `temp-{timestamp}`
+- Mock responses allow UI to function independently
+- Data is not persisted to backend, but is available locally
+- Once backend endpoint is available, real responses are used
+
+### Field Naming
+- All field names use **camelCase** (not snake_case)
+- Dates are ISO 8601 format with timezone
+- UUIDs are standard UUID v4 format strings
+- Arrays indicated by square brackets `[]`
+
+### Data Validation
+- Max length constraints enforced by backend
+- Required fields validated before operation
+- Enum values must match exactly
+- Nested objects fully validated recursively
+
+### Rate Limiting
+Not specified in this version. Implement per-service requirements.
+
+### Caching
+Clients may cache GET responses but should respect `updatedAt` timestamps and refresh when needed.

+# Common Patterns & Data Models
+
+**Version:** 4.0  
+**Last Updated:** December 26, 2025  
+**Purpose:** Shared patterns, authentication, error handling, and data models across all services
+
+[← Back to Index](./index.md)
+
+## Changelog
+
+| Version | Date | Changes |
+|---------|------|----------|
+| 4.0 | December 26, 2025 | **BREAKING:** Standardized all enum values and type definitions to camelCase (e.g., `'not_started'` → `'notStarted'`, `'in_progress'` → `'inProgress'`). Updated pagination query parameter from `limit` to `pageSize`. Added comprehensive data models section with common camelCase field names. |
+| 3.0 | October 13, 2025 | Multi-service documentation split |
+
+---
+
+## Authentication and Headers
+
+### Required Headers
+
+All protected endpoints require these headers:
+
+```http
+Authorization: Bearer {accessToken}
+X-Tenant-Id: {tenantId}
+Content-Type: application/json
+```
+
+### Special Headers
+
+#### X-Frontend-Base-Url
+**Used by:** Account Service auth endpoints that trigger emails
+
+**Value:** `window.location.origin`
+
+**Endpoints:**
+- `POST /auth/register`
+- `POST /auth/resend-confirmation`
+- `POST /auth/login` (if `REACT_APP_FE_BASE_HEADER_LOGIN=true`)
+
+**Purpose:** Backend includes this URL in email links for email verification, password reset, etc.
+
+**Implementation:**
+```typescript
+// Automatically added by accountClient interceptor
+if (/\/auth\/(register|resend-confirmation)/.test(url)) {
+  config.headers['X-Frontend-Base-Url'] = window.location.origin;
+}
+```
+
+---
+
+## Token Management
+
+### Storage
+
+Tokens stored in `localStorage`:
+
+| Key | Value | Purpose |
+|-----|-------|---------|
+| `accessToken` | JWT access token | Authentication for API requests |
+| `refreshToken` | JWT refresh token | Obtain new access token |
+| `tenantId` | Tenant/organization ID | Multi-tenant data isolation |
+
+### Token Lifecycle
+
+```
+1. User logs in
+   ↓
+2. Receive accessToken (15min TTL), refreshToken (30d TTL)
+   ↓
+3. Store in localStorage
+   ↓
+4. Include in all API requests via Authorization header
+   ↓
+5. On 401 response:
+   a. Call POST /auth/refresh with refreshToken
+   b. Receive new accessToken + refreshToken
+   c. Update localStorage
+   d. Retry original request
+   ↓
+6. If refresh fails: clear tokens, redirect to login
+```
+
+### Automatic Token Refresh
+
+All service clients implement automatic token refresh on 401 responses:
+
+**Account & Coaching Services** (`api.ts`):
+```typescript
+this.accountClient.interceptors.response.use(
+  (response) => response,
+  async (error) => {
+    if (error.response?.status === 401) {
+      await this.refreshToken();
+      // Retry original request
+    }
+    return Promise.reject(error);
+  }
+);
+```
+
+**Traction Service** (`traction.ts`):
+```typescript
+// Queue-based refresh to handle concurrent 401s
+traction.interceptors.response.use(
+  (response) => response,
+  async (error) => {
+    if (error.response?.status === 401 && !error.config._retry) {
+      if (isRefreshing) {
+        // Queue request during refresh
+        return new Promise((resolve, reject) => {
+          pendingQueue.push({resolve, reject});
+        }).then((token) => {
+          error.config.headers.Authorization = `Bearer ${token}`;
+          return traction.request(error.config);
+        });
+      }
+      
+      isRefreshing = true;
+      error.config._retry = true;
+      
+      const ok = await apiClient.refreshToken();
+      const token = apiClient.getToken();
+      
+      processQueue(null, token);
+      
+      if (ok && token) {
+        error.config.headers.Authorization = `Bearer ${token}`;
+        return traction.request(error.config);
+      }
+    }
+    return Promise.reject(error);
+  }
+);
+```
+
+---
+
+## Error Handling
+
+### Standard Error Response
+
+All services return consistent error format:
+
+```json
+{
+  "success": false,
+  "error": "Human-readable error message",
+  "code": "ERROR_CODE",
+  "details": {}  // Optional: Additional context for the error
+}
+```
+
+**Field Descriptions:**
+- `success`: Always `false` for error responses
+- `error`: Human-readable message describing what went wrong
+- `code`: Machine-readable error code (see Common Error Codes table)
+- `details`: Optional object with additional error context (field names, validation errors, resource IDs, etc.)
+
+**Examples:**
+
+Validation error:
+```json
+{
+  "success": false,
+  "error": "Email is required",
+  "code": "VALIDATION_ERROR",
+  "details": {
+    "field": "email"
+  }
+}
+```
+
+Multiple validation errors:
+```json
+{
+  "success": false,
+  "error": "Validation failed for multiple fields",
+  "code": "VALIDATION_ERROR",
+  "details": {
+    "errors": [
+      {"field": "email", "message": "Email is required"},
+      {"field": "password", "message": "Password must be at least 8 characters"}
+    ]
+  }
+}
+```
+
+Resource not found:
+```json
+{
+  "success": false,
+  "error": "User not found",
+  "code": "RESOURCE_NOT_FOUND",
+  "details": {
+    "resourceType": "User",
+    "resourceId": "user_123"
+  }
+}
+```
+
+### Common Error Codes
+
+| Code | HTTP Status | Description | Usage |
+|------|-------------|-------------|-------|
+| `VALIDATION_ERROR` | 400, 422 | Input validation failed | Field validation, format errors |
+| `UNAUTHORIZED` | 401 | Authentication required | Missing/invalid token |
+| `FORBIDDEN` | 403 | Insufficient permissions | User lacks required access |
+| `RESOURCE_NOT_FOUND` | 404 | Resource does not exist | Invalid ID, deleted resource |
+| `DUPLICATE_RESOURCE` | 409 | Resource already exists | Unique constraint violation |
+| `BUSINESS_RULE_VIOLATION` | 400 | Business logic violation | Invalid operation per domain rules |
+| `INTERNAL_SERVER_ERROR` | 500 | Unexpected error | Server-side errors |
+
+### HTTP Status Codes
+
+| Code | Meaning | Frontend Action |
+|------|---------|----------------|
+| 200 | Success | Process response (check `success` field) |
+| 401 | Unauthorized | Trigger token refresh, retry request |
+| 403 | Forbidden | Show "Access Denied" message |
+| 404 | Not Found | Handle missing resource |
+| 422 | Validation Error | Show field-specific errors |
+| 500 | Server Error | Show error message, enable retry |
+
+### Frontend Error Handling Patterns
+
+#### Generic Error Handler
+```typescript
+try {
+  const response = await apiCall();
+  if (!response.success) {
+    showError(response.error);
+    return;
+  }
+  // Process response.data
+} catch (error: any) {
+  if (error.response?.status === 401) {
+    // Handled by interceptor
+  } else if (error.response?.status === 403) {
+    showError("You don't have permission to perform this action");
+  } else {
+    showError(error.response?.data?.error || "An error occurred");
+  }
+}
+```
+
+#### Validation Error Display
+```typescript
+if (error.response?.status === 422) {
+  const validationErrors = error.response.data.errors;
+  // Display field-specific errors
+  Object.keys(validationErrors).forEach(field => {
+    setFieldError(field, validationErrors[field]);
+  });
+}
+```
+
+#### Retry Logic
+```typescript
+async function apiCallWithRetry(maxRetries = 3) {
+  for (let i = 0; i < maxRetries; i++) {
+    try {
+      return await apiCall();
+    } catch (error: any) {
+      if (i === maxRetries - 1) throw error;
+      if (error.response?.status === 500) {
+        await delay(Math.pow(2, i) * 1000); // Exponential backoff
+        continue;
+      }
+      throw error;
+    }
+  }
+}
+```

+```
+
+### Subscription
+
+```typescript
+type SubscriptionFrequency = 'monthly' | 'yearly';
+type SubscriptionStatus = string; // Dynamic, e.g., 'active', 'trialing', 'pastDue', 'cancelled'

+
+## Environment Configuration
+
+### Required Environment Variables
+
+```bash
+# Service Base URLs
+REACT_APP_ACCOUNT_API_URL=https://api.dev.purposepath.app/account/api/v1
+REACT_APP_COACHING_API_URL=https://api.dev.purposepath.app/coaching/api/v1
+REACT_APP_TRACTION_API_URL=https://api.dev.purposepath.app/traction/api/v1
+
+# Feature Flags
+REACT_APP_MOCK_MODE=false               # Global mock mode toggle
+REACT_APP_MOCK_ACCOUNT=false            # Mock Account Service only
+REACT_APP_MOCK_COACHING=false           # Mock Coaching Service only
+REACT_APP_MOCK_TRACTION=false           # Mock Traction Service only
+REACT_APP_FEATURE_REALTIME=true         # Enable real-time SSE features
+
+# SSE Configuration
+REACT_APP_SSE_BASE_URL=https://api.dev.purposepath.app/traction/api/v1
+
+# Optional Features
+REACT_APP_FE_BASE_HEADER_LOGIN=false    # Add X-Frontend-Base-Url to login requests
+```
+
+### Environment-Specific URLs
+
+| Environment | Base URL |
+|-------------|----------|
+| Development | `https://api.dev.purposepath.app` |
+| Staging | `https://api.staging.purposepath.app` |
+| Production | `https://api.purposepath.app` |
+
+### Mock Mode Behavior
+
+When service-specific mock flags are enabled:
+- API calls return realistic mock data
+- No network requests made to backend
+- Suitable for development and offline testing
+- Each service can be mocked independently
+
+**Example:**
+```bash
+REACT_APP_MOCK_ACCOUNT=false  # Real Account API
+REACT_APP_MOCK_COACHING=true  # Mock Coaching API
+REACT_APP_MOCK_TRACTION=false # Real Traction API
+```
+
+---
+
+## API Response Patterns
+
+### Success Response
+
+```typescript
+interface ApiResponse<T> {
+  success: true;
+  data: T;
+}
+```
+
+### Paginated Response
+
+```typescript
+interface PaginatedResponse<T> {
+  success: true;
+  data: T[];
+  pagination: {
+    page: number;
+    pageSize: number;
+    total: number;
+    totalPages: number;
+  };
+}
+```
+
+### Error Response
+
+```typescript
+interface ErrorResponse {
+  success: false;
+  error: string;
+  code?: string;
+  errors?: Record<string, string>; // Field-specific validation errors
+}
+```
+
+---
+
+## Data Models
+
+### Standard Field Naming
+
+All API responses use **camelCase** for JSON property names:
+
+**Common Fields:**
+- `accessToken`, `refreshToken` - Authentication tokens
+- `userId`, `tenantId` - Entity identifiers
+- `firstName`, `lastName` - User name fields
+- `avatarUrl` - User profile picture URL
+- `createdAt`, `updatedAt` - Timestamps
+- `ownerId` - Resource owner identifier
+- `valueTags` - Array of value identifiers
+- `sharedMeasureId` - Shared Measure identifier
+- `thresholdPct` - Percentage threshold value
+- `businessImpact` - Business impact description
+- `assignedPersonId` - Person assignment identifier
+- `newPassword` - New password for updates
+
+### TypeScript Model Example
+
+**User Profile** (`api.ts`):
+```typescript
+interface UserProfile {
+  userId: string;
+  email: string;
+  firstName: string;
+  lastName: string;
+  avatarUrl?: string;
+  createdAt: string;
+  updatedAt: string;
+  status: string;
+  emailVerified: boolean;
+  preferences: Record<string, any>;
+}
+```
+
+---
+
+## Caching Strategy
+
+### Client-Side Caching
+
+**Goals Cache** (`goal-service.ts`):
+```typescript
+class GoalCache {
+  private goalListCache: Goal[] | null = null;
+  private goalCache: Map<string, Goal> = new Map();
+  
+  invalidateAll(): void {
+    this.goalListCache = null;
+    this.goalCache.clear();
+    this.notifyInvalidation();
+  }
+}
+```
+
+**Alignment Cache** (`alignment-cache-service.ts`):
+```typescript
+// Caches alignment calculations to reduce API calls
+// Cache key: hash of goal intent + strategies + Measures
+// TTL: 5 minutes
+```
+
+**When to Invalidate:**
+- After create/update/delete operations
+- On user-triggered refresh
+- After certain time periods (TTL)
+
+---
+
+## Optimistic Updates
+
+Frontend implements optimistic updates for better UX:
+
+**Pattern** (`optimistic-updates.ts`):
+```typescript
+async function updateWithOptimism(
+  optimisticUpdate: () => void,
+  apiCall: () => Promise<any>,
+  rollback: () => void
+) {
+  optimisticUpdate(); // Update UI immediately
+  
+  try {
+    await apiCall(); // Make API call
+  } catch (error) {
+    rollback(); // Revert on failure
+    showError(error);
+  }
+}
+```
+
+**Example:**
+```typescript
+// Update goal status immediately
+setGoalStatus(goalId, 'completed');
+
+try {
+  await goalService.closeGoal(goalId, {finalStatus: 'completed'});
+} catch (error) {
+  // Revert to previous status
+  setGoalStatus(goalId, previousStatus);
+  showError('Failed to close goal');
+}
+```
+
+---
+
+## Real-Time Connection Management
+
+**SSE Connection** (`realtime.ts`):
+```typescript
+class RealtimeService {
+  private connections: Map<string, EventSource> = new Map();
+  
+  subscribe(goalId: string, callback: (event) => void) {
+    const url = `${SSE_BASE_URL}/realtime/goals/${goalId}/activity?` +
+      `accessToken=${token}&tenantId=${tenantId}`;
+    
+    const eventSource = new EventSource(url);
+    
+    eventSource.addEventListener('activityCreated', callback);
+    eventSource.addEventListener('error', () => {
+      // Auto-reconnect with exponential backoff
+      this.reconnect(goalId, callback);
+    });
+    
+    this.connections.set(goalId, eventSource);
+  }
+  
+  unsubscribe(goalId: string) {
+    const connection = this.connections.get(goalId);
+    if (connection) {
+      connection.close();
+      this.connections.delete(goalId);
+    }
+  }
+}
+```
+
+**Connection Features:**
+- Auto-reconnect on disconnect
+- Exponential backoff for reconnection attempts
+- Event deduplication using `lastEventId`
+- Graceful fallback to polling if SSE unavailable
+
+---
+
+## Performance Considerations
+
+### Request Batching
+
+Batch-related entity queries:
+```typescript
+// Instead of N requests
+for (const actionId of actionIds) {
+  await getActionGoals(actionId);
+}
+
+// Make 1 request
+const goalsMap = await getActionGoalRelationships({actionIds});
+```
+
+### Debouncing
+
+Debounce expensive operations:
+```typescript
+const debouncedAlignment = debounce(async () => {
+  await calculateAlignment(goal);
+}, 1000); // Wait 1s after last change
+```
+
+### Lazy Loading
+
+Load data on-demand:
+```typescript
+// Load goals list immediately
+const goals = await getGoals();
+
+// Load full goal details only when opened
+const goalDetails = await getGoalById(selectedGoalId);
+```
+
+---
+
+## Health Check Endpoints (Kubernetes Patterns)
+
+### Overview
+
+All services implement standard Kubernetes health check patterns for infrastructure monitoring, orchestration, and load balancing. These endpoints provide different levels of health information for various use cases.
+
+### Service Availability
+
+| Service | Base Route | Endpoints |
+|---------|-----------|-----------|
+| Account Service | `/health` | All 4 health check types |
+| Traction Service | `/health` | All 4 health check types |
+
+### Endpoints
+
+#### 1. GET /health - Basic Health Check
+
+**Purpose:** Lightweight availability check for load balancers and uptime monitoring
+
+**Authentication:** None (public endpoint)
+
+**Request:** No parameters
+
+**Response:** `ApiResponse<HealthCheckResponse>` (200 OK)
+
+```json
+{
+  "success": true,
+  "data": {
+    "status": "Healthy",
+    "service": "PurposePath Account Lambda",
+    "version": "1.0.0",
+    "timestamp": "2025-10-17T12:00:00Z",
+    "environment": "production"
+  }
+}
+```
+
+**Use Cases:**
+
+- Load balancer health checks
+- Basic uptime monitoring
+- Service discovery verification
+- Quick availability checks
+
+**Check Frequency:** High (every 5-10 seconds)
+
+---
+
+#### 2. GET /health/detailed - Detailed Health Status
+
+**Purpose:** Comprehensive health check with dependency status and diagnostics
+
+**Authentication:** None (public endpoint)
+
+**Request:** No parameters
+
+**Response:** `ApiResponse<HealthCheckResponse>` (200 OK or 503 Service Unavailable)
+
+**Success Response (200):**
+
+```json
+{
+  "success": true,
+  "data": {
+    "status": "Healthy",
+    "service": "PurposePath Traction Lambda",
+    "version": "1.0.0",
+    "timestamp": "2025-10-17T12:00:00Z",
+    "environment": "production",
+    "checks": [
+      {
+        "component": "API",
+        "status": "Healthy",
+        "description": "API is responsive"
+      },
+      {
+        "component": "Application",
+        "status": "Healthy",
+        "description": "Application is running normally"
+      },
+      {
+        "component": "Configuration",
+        "status": "Healthy",
+        "description": "Environment: production"
+      }
+    ]
+  }
+}
+```
+
+**Failure Response (503):**
+```json
+{
+  "success": true,
+  "data": {
+    "status": "Unhealthy",
+    "service": "PurposePath Account Lambda",
+    "version": "1.0.0",
+    "timestamp": "2025-10-17T12:00:00Z",
+    "environment": "production",
+    "checks": [
+      {
+        "component": "Application",
+        "status": "Unhealthy",
+        "description": "Database connection failed"
+      }
+    ]
+  }
+}
+```
+
+**Use Cases:**
+
+- Monitoring dashboards (Datadog, New Relic, CloudWatch)
+- Detailed service health debugging
+- Dependency health tracking
+- Root cause analysis during incidents
+
+**Check Frequency:** Medium (every 30-60 seconds)
+
+---
+
+#### 3. GET /health/ready - Readiness Probe
+
+**Purpose:** Kubernetes readiness probe - determines if pod should receive traffic
+
+**Authentication:** None (public endpoint)
+
+**Request:** No parameters
+
+**Response:** 200 OK or 503 Service Unavailable
+
+**Success Response (200):**
+
+```json
+{
+  "success": true,
+  "data": {
+    "status": "Ready",
+    "timestamp": "2025-10-17T12:00:00Z",
+    "message": "Service is ready to accept requests"
+  }
+}
+```
+
+**Failure Response (503):**
+
+```json
+{
+  "success": false,
+  "error": "Service not ready"
+}
+```
+
+**Kubernetes Behavior:**
+
+- **200 response:** Pod added to service load balancer pool (receives traffic)
+- **503 response:** Pod removed from load balancer pool (stops receiving traffic)
+- **Does NOT restart pod** (unlike liveness probe)
+- Pod stays running but excluded from traffic routing
+
+**Use Cases:**
+
+- Zero-downtime deployments
+- Gradual rollouts and canary deployments
+- Prevents traffic to initializing pods
+- Warm-up period handling
+- Database connection establishment
+- Cache warming
+
+**Check Frequency:** High (every 10 seconds)
+
+**Example Kubernetes Configuration:**
+
+```yaml
+readinessProbe:
+  httpGet:
+    path: /health/ready
+    port: 8080
+  initialDelaySeconds: 10
+  periodSeconds: 10
+  timeoutSeconds: 5
+  successThreshold: 1
+  failureThreshold: 3
+```
+
+---
+
+#### 4. GET /health/live - Liveness Probe
+
+**Purpose:** Kubernetes liveness probe - determines if pod should be restarted
+
+**Authentication:** None (public endpoint)
+
+**Request:** No parameters
+
+**Response:** 200 OK (always successful unless service is completely unresponsive)
+
+**Response (200):**
+
+```json
+{
+  "success": true,
+  "data": {
+    "status": "Alive",
+    "timestamp": "2025-10-17T12:00:00Z",
+    "message": "Service is running"
+  }
+}
+```
+
+**Kubernetes Behavior:**
+
+- **200 response:** Pod continues running normally
+- **No response or timeout:** Kubernetes **restarts the pod**
+- **More lenient than readiness** (higher thresholds)
+- Used to detect deadlocks, memory leaks, or unrecoverable states
+
+**Use Cases:**
+
+- Automatic recovery from deadlocks
+- Memory leak detection and recovery
+- Thread hang detection
+- Self-healing infrastructure
+- Recovery from unrecoverable errors
+
+**Check Frequency:** Low (every 30-60 seconds)
+
+**Example Kubernetes Configuration:**
+
+```yaml
+livenessProbe:
+  httpGet:
+    path: /health/live
+    port: 8080

+### Health Check Comparison Table
+
+| Endpoint | Purpose | K8s Feature | Failure Behavior | Check Frequency | Authentication |
+|----------|---------|-------------|------------------|-----------------|----------------|
+| `/health` | Basic availability | Load Balancer | None (monitoring only) | High (5-10s) | None |
+| `/health/detailed` | Diagnostics | Observability | None (monitoring only) | Medium (30-60s) | None |
+| `/health/ready` | Traffic routing | Readiness Probe | Remove from LB pool | High (10s) | None |
+| `/health/live` | Pod health | Liveness Probe | **Restart pod** | Low (30-60s) | None |
+
+### Readiness vs Liveness
+
+**Key Difference:**
+
+```text
+Readiness: "Can I send traffic to this pod?"
+Liveness:  "Should I restart this pod?"
+```
+
+**Example Scenario:**
+
+1. Pod starts → Readiness fails (503) → No traffic sent
+2. Pod initializes → Readiness passes (200) → Traffic starts flowing
+3. Pod runs fine → Both probes pass (200)
+4. Database connection lost → Readiness fails (503) → Traffic stops, **pod stays running**
+5. Database reconnects → Readiness passes (200) → Traffic resumes
+6. Pod deadlocks → Liveness fails (no response) → **Kubernetes restarts pod**
+
+### Monitoring Integration
+
+#### Datadog Integration
+
+```yaml
+# datadog-agent.yaml
+checks:
+  - name: purposepath_health
+    url: https://api.purposepath.app/health/detailed
+    method: GET
+    interval: 60
+    alert_on_failure: true
+```
+
+#### New Relic Synthetic Monitor
+
+```javascript
+// New Relic Synthetic Script
+const assert = require('assert');
+
+$http.get('https://api.purposepath.app/health/detailed', function(err, response, body) {
+  assert.equal(response.statusCode, 200, 'Expected 200 OK');
+  const data = JSON.parse(body);
+  assert.equal(data.data.status, 'Healthy', 'Service should be healthy');
+  
+  data.data.checks.forEach(check => {
+    assert.equal(check.status, 'Healthy', `${check.component} should be healthy`);
+  });
+});
+```
+
+#### CloudWatch Alarms
+
+```bash
+# Create CloudWatch alarm for health check failures
+aws cloudwatch put-metric-alarm \
+  --alarm-name purposepath-account-unhealthy \
+  --alarm-description "Alert when Account service is unhealthy" \
+  --metric-name HealthCheckStatus \
+  --namespace PurposePath/Services \
+  --statistic Average \
+  --period 60 \
+  --threshold 1 \
+  --comparison-operator LessThanThreshold \
+  --evaluation-periods 3
+```
+
+### Frontend Integration Example
+
+Frontend can use health checks for status pages or admin dashboards:
+
+```typescript
+// Status page component
+async function checkServiceHealth() {
+  try {
+    const accountHealth = await fetch('/api/v1/health');
+    const tractionHealth = await fetch('/api/v1/health');
+    
+    return {
+      account: accountHealth.ok ? 'operational' : 'degraded',
+      traction: tractionHealth.ok ? 'operational' : 'degraded'
+    };
+  } catch (error) {
+    return {
+      account: 'down',
+      traction: 'down'
+    };
+  }
+}
+
+// Admin dashboard with detailed status
+async function getDetailedServiceStatus() {
+  const response = await fetch('/api/v1/health/detailed');
+  const data = await response.json();
+  
+  return {
+    status: data.data.status,
+    version: data.data.version,
+    checks: data.data.checks,
+    timestamp: data.data.timestamp
+  };
+}
+```

+
+### Best Practices
+
+1. **Readiness Probe:**
+
+   - Check all critical dependencies (database, cache, external APIs)
+   - Return 503 if any critical dependency is unavailable
+   - Use shorter timeouts and more frequent checks
+   - Should recover automatically when dependencies recover
+
+2. **Liveness Probe:**
+
+   - Keep checks simple and fast
+   - Only fail for unrecoverable errors (deadlocks, memory exhaustion)
+   - Use longer timeouts and less frequent checks
+   - Avoid checking external dependencies (use readiness for that)
+
+3. **Detailed Health:**
+
+   - Include all dependency statuses
+   - Add latency metrics
+   - Include version information
+   - Log failures for debugging
+
+4. **Basic Health:**
+
+   - Keep extremely lightweight
+   - Return quickly
+   - Minimal dependencies
+   - Suitable for high-frequency polling
+
+---
+
+## Security Best Practices
+
+1. **Never log sensitive data:**
+
+   ```typescript
+   // Bad
+   console.log('Token:', accessToken);
+   
+   // Good
+   console.log('Token:', accessToken.slice(0, 10) + '...');
+   ```
+
+2. **Validate on both client and server:**
+
+   - Client validation for UX
+   - Server validation for security
+
+3. **Handle token expiration gracefully:**
+
+   - Auto-refresh on 401
+   - Clear tokens and redirect on refresh failure
+
+4. **Use HTTPS in production:**
+
+   - All API endpoints must use HTTPS
+   - No mixed content
+
+5. **Sanitize user input:**
+
+   - Especially in rich text editors
+   - Prevent XSS attacks

+
+## Overview
+
+The Dashboard API provides endpoints for managing user-customizable dashboards with drag-and-drop widgets. The API is split across two services:
+
+- **Account Service**: Manages dashboard configuration and templates (user preferences, layout state)
+- **Traction Service**: Provides operational data for widgets (actions, goals, measures, issues, etc.)
+
+### Key Concepts
+
+- **Dashboard Config**: A user's dashboard layout state (widgets + layout)
+- **Widget Definition**: A widget type from the catalog (e.g., "action-list", "measure-graph")
+- **Widget Instance**: A specific widget placed on a user's dashboard
+- **Widget Settings**: Per-widget-instance configuration used by Traction to generate widget data
+- **Layout**: Position and size of widgets in a responsive grid
+- **Template**: Pre-configured dashboard layouts users can apply
+
+---

+Authorization: Bearer {token}
+X-Tenant-Id: {tenantId}
+```
+
+### Example Response
+
+```json

+  }
+}
+```
+
+### Business Rules
+
+- Returns default configuration if user has no saved config
+- Configuration is user-specific (isolated by userId within tenant)
+- Widget instances must reference valid widget IDs from the catalog
+- **Frontend owns widget instance IDs** (`widgets[].instanceId`)
+- When returning a system default template (no user config exists), `widgets[].instanceId` may be null
+  - When `instanceId` is null, the backend must provide `widgets[].layoutId` and `layouts[].i` must match that layoutId
+  - The frontend must immediately generate `instanceId`s for those widgets, update layouts to use the new instanceIds, and persist via `PUT /account/api/v1/dashboard/config`
+  - Settings endpoints require a non-null instanceId (settings cannot be read/updated until the frontend assigns an instanceId)
+  - `layoutId` is **transient** and **response-only**: it is used only to correlate `widgets[]` with `layouts[]` in the default template response and is never persisted
+- Layout positions must be non-negative integers
+
+---

+## Get Widget Catalog
+
+**GET** `/account/api/v1/dashboard/widgets`
+
+Retrieve the complete widget catalog with all available widget definitions. This provides metadata about widgets including their categories, descriptions, size constraints, and accessibility. The frontend uses this as the single source of truth for available widgets.
+
+**Note**: Widget accessibility is determined by the backend based on the user's current subscription tier and enabled features. Refresh strategies and intervals are implementation details handled by individual widget components, not part of the catalog definition.

+### Field Constraints
+
+- **Widget ID**: Must be unique, alphanumeric with hyphens, stable across system updates
+- **Category**: Must exactly match one of the valid category values listed above
+- **Size constraints**:
+  - All size values must be positive integers
+  - `minW` and `maxW` must be between 1 and 12 (grid columns)
+  - `minW` ≤ `defaultW` ≤ `maxW`
+  - `minH` ≤ `defaultH` ≤ `maxH`
+- **Tags**: Array of strings, optional. Used for search/filtering only. No validation rules on tag values.
+- **Preview Image**: Must be a valid URL if provided
+
+### Business Rules
+
+- Returns all widgets available in the system, regardless of user's subscription tier
+- `isAccessible` field is calculated by backend based on:
+  - User's current subscription tier
+  - Enabled feature flags for the user
+  - Backend-evaluated access rules
+- Widget IDs must remain stable across updates (used in saved dashboard configurations)
+- Size constraints use grid units (default grid is 5 columns for large screens, see Grid Configuration section)
+- Descriptions and metadata can be updated dynamically without frontend code changes
+- Refresh strategies and intervals are widget implementation details handled in widget code, not included in catalog

+
+## Widget Instance Settings
+
+Widget settings are stored per user and per widget instance. Widgets use these settings to determine what data to return.
+
+Dashboard config (Account Service) does not store widget settings.
+
+### Get Widget Instance Settings
+
+**GET** `/traction/api/v1/dashboard/widgets/{widgetId}/instances/{instanceId}/settings`
+
+Retrieve current settings for a specific widget instance.
+
+If no settings exist yet, returns an empty `settings` object. **Missing fields imply default operational behavior** (either a default value or a default rule handled by the widget/backend), e.g.:
+- If a filter setting is missing, show all items
+- If a "next X days" setting is missing, default to 7 days (widget-defined)
+
+The `version` returned is the widget's current version (used to interpret settings and schema).
+
+### Response
+
+```json
+{
+  "success": true,
+  "data": {
+    "widgetId": "hot-list",
+    "instanceId": "widget-1704700800000-abc123",
+    "version": 1,
+    "settings": {},
+    "updatedAt": "2026-01-12T12:00:00Z"
+  }
+}
+```
+
+### Save Widget Instance Settings
+
+**PUT** `/traction/api/v1/dashboard/widgets/{widgetId}/instances/{instanceId}/settings`
+
+Persist settings for a specific widget instance.
+
+### Request Body
+
+```json
+{
+  "version": 1,
+  "settings": {
+    "maxItemsPerSection": 5,
+    "showUrgentIssues": true
+  }
+}
+```
+
+### Response
+
+```json
+{
+  "success": true,
+  "data": {
+    "widgetId": "hot-list",
+    "instanceId": "widget-1704700800000-abc123",
+    "version": 1,
+    "settings": {
+      "maxItemsPerSection": 5,
+      "showUrgentIssues": true
+    },
+    "updatedAt": "2026-01-12T12:05:00Z"
+  }
+}
+```
+
+---
+
+### Reset Widget Instance Settings
+
+**POST** `/traction/api/v1/dashboard/widgets/{widgetId}/instances/{instanceId}/settings/reset`
+
+Reset settings for a widget instance to its defaults as defined by the widget's settings schema.
+
+- If the widget defines no defaults, the backend returns an empty `settings` object.
+- The backend persists the reset result so subsequent calls return the same values.
+
+### Response
+
+```json
+{
+  "success": true,
+  "data": {
+    "widgetId": "hot-list",
+    "instanceId": "widget-1704700800000-abc123",
+    "version": 1,
+    "settings": {
+      "maxItemsPerSection": 5,
+      "showUrgentIssues": true
+    },
+    "updatedAt": "2026-01-12T12:10:00Z"
+  }
+}
+```
+
+---
+
+## Widget Settings Schema
+
+**GET** `/traction/api/v1/dashboard/widgets/{widgetId}/settings/schema`
+
+Return the widget's **settings UI schema** (including defaults) so the frontend can auto-generate a standardized settings dialog.
+
+Notes:
+- **Schema is never null.** Widgets with no settings return `fields: []`.
+- Settings represent **operational configuration only** (not layout/position/size).
+- The settings dialog is schema-driven by default. Widgets may opt into a **custom settings dialog** via `ui.mode = "custom"`.
+- Frontend uses `defaultValue` to prefill the dialog when a setting key is missing from stored settings.

+      "changePercent": 26.7,
+      "projection": 102000
+    }
+  }
+}
+```
+
+**Note:** The `dataPoints` array includes all data points (both actual and target values) with an explicit `dataType` field indicating whether each point is an "actual" recorded value or a "target" planned value. This allows the frontend to distinguish between actual and target data points and supports scenarios where there may be targets without actuals or vice versa.

+# Data Types Summary
+
+## Widget Categories
+
+| Category | Description | Example Widgets |
+|----------|-------------|-----------------|
+| `overview` | Summary/aggregation | Hot List, Performance Score |
+| `actions` | Action management | Action List, Actions By Status |
+| `goals` | Goal tracking | Goal Progress |
+| `measures` | Metric visualization | Measure Graph |
+| `issues` | Issue management | Issue List |
+| `insights` | AI/coaching | AI Insights |
+| `team` | Team analytics | Team Alignment |
+
+## Widget Access Control
+
+Widget accessibility is determined by the backend based on:
+- User's current subscription tier (free, starter, professional, enterprise)
+- Enabled feature flags for the user
+- Dynamic business rules managed by the backend
+
+The widget catalog API returns `isAccessible: boolean` for each widget, eliminating the need for the frontend to evaluate tier requirements or feature flags. This allows the backend to manage tier definitions and access rules dynamically without requiring frontend code changes.
+
+**Note**: Tier and feature requirements are internal backend concerns and are not exposed in the API response.
+
+## Grid Configuration
+
+```typescript
+const GRID_CONFIG = {
+  cols: { lg: 5, md: 4, sm: 3, xs: 2 },
+  rowHeight: 120,                    // pixels
+  breakpoints: { lg: 1200, md: 996, sm: 768, xs: 0 },
+  containerPadding: [16, 16],
+  margin: [16, 16],
+};

+## Implementation Details
+
+### Frontend Service Files
+
+| Service | Primary Client | Implementation Files |
+|---------|----------------|---------------------|
+| User & Tenant Mgmt | `api.ts` → `accountClient` | `src/services/api.ts` |
+| Business Foundation | `business-foundation-service.ts` → `accountClient` | `src/services/business-foundation-service.ts`, `src/types/business-foundation.ts` |
+| People | TBD | TBD |
+| Org Structure | TBD | TBD |
+| Coaching | `api.ts` → `coachingClient` | `src/services/api.ts`, `src/services/alignment-engine-service.ts`, `src/services/strategy-suggestion-service.ts`, `src/services/measure-recommendation-service.ts`, `src/services/operations-ai-service.ts` |
+| Traction | `traction.ts` → `traction` | `src/services/traction.ts`, `src/services/goal-service.ts`, `src/services/action-service.ts`, `src/services/issue-service.ts`, `src/services/operations-traction-service.ts`, `src/services/measure-planning-service.ts`, `src/services/realtime.ts` |
+
+### Authentication Flow
+
+1. User logs in → POST /auth/login (Account Service)
+2. Receives: accessToken, refreshToken, user, tenant
+3. Stores: localStorage.accessToken, localStorage.refreshToken, localStorage.tenantId
+4. All subsequent requests include:
+   - Authorization: Bearer {accessToken}
+   - X-Tenant-Id: {tenantId}
+5. On 401 response → POST /auth/refresh (Account Service)
+6. Updates tokens and retries original request
+
+### Request Interceptors
+
+All service clients (accountClient, coachingClient, traction) implement:
+
+- **Token injection**: Automatically adds `Authorization: Bearer {token}` header
+- **Tenant header**: Automatically adds `X-Tenant-Id` header
+- **Token refresh**: On 401 response, attempts token refresh and retries request
+- **Special headers**: Adds `X-Frontend-Base-Url` for email-triggering endpoints
+

+## Overview
+
+The Organizational Structure module manages the organizational hierarchy through roles, positions, organization units, and their relationships. It provides the foundation for the accountability framework within PurposePath.
+
+### Architecture Overview
+
+The org structure is built on these key entities:
+
+```

+### Key Concepts
+
+- **Role**: A template defining responsibilities and accountability (e.g., "Software Engineer", "VP Sales")
+- **RoleType**: Classification of roles (Executive, Management, Professional, Associate)
+- **Position**: An instance of a role within an organization unit, optionally filled by a person
+- **OrganizationUnit**: A logical grouping (Company, Division, Department, Team)
+- **OrganizationUnitType**: Classification of organization units
+- **Position Relationship**: Non-hierarchical connection between positions (Support, Advise, Collaborate, Mentor)
+- **Reports To**: Hierarchical relationship defined on Position entity
+

+
+**Note:** "Reports To" is NOT a relationship type. Reporting hierarchy is defined directly on the Role entity via the `reportsToRoleId` field. This keeps the hierarchy simple and unidirectional.
+
+---
+
+## Frontend Implementation Notes
+
+### Org Chart Visualization
+
+```typescript
+// React component with react-organizational-chart
+import { Tree, TreeNode } from 'react-organizational-chart';
+
+const OrgChartNode = ({ role, occupant, isVacant, children }) => (
+  <TreeNode label={
+    <div className={`org-node ${isVacant ? 'vacant' : ''}`}>
+      <div className="role-name">{role.name}</div>
+      {occupant ? (
+        <div className="occupant">{occupant.name}</div>
+      ) : (
+        <div className="vacant-badge">Vacant</div>
+      )}
+    </div>
+  }>
+    {children.map(child => (
+      <OrgChartNode key={child.role.id} {...child} />
+    ))}
+  </TreeNode>
+);
+```
+
+### Circular Reference Prevention (Frontend - Reports To Only)
+
+```typescript
+// Before setting reportsToRoleId, check for cycles in the hierarchy
+const wouldCreateCycle = (
+  roleId: string, 
+  newReportsToId: string, 
+  roles: Role[]
+): boolean => {
+  const visited = new Set<string>();
+  let current = newReportsToId;
+  
+  while (current) {
+    if (current === roleId) return true; // Found cycle!
+    if (visited.has(current)) break; // Already visited, no cycle to us
+    visited.add(current);
+    
+    // Find what this role reports to
+    const role = roles.find(r => r.id === current);
+    current = role?.reportsToRoleId || '';
+  }
+  
+  return false;
+};
+
+// Usage in form validation
+const handleReportsToChange = (newReportsToId: string) => {
+  if (wouldCreateCycle(editingRole.id, newReportsToId, allRoles)) {
+    showError('This would create a circular reporting structure');
+    return;
+  }
+  // Proceed with update...
+};
+```
+
+**Note:** This validation only applies to `reportsToRoleId` on the Role entity. Role relationships (SUPPORT, ADVISE, etc.) are not hierarchical and don't need cycle detection.
+

+
+**Version:** 2.0  
+**Last Updated:** December 26, 2025  
+**Service Base URL:** `{REACT_APP_ACCOUNT_API_URL}` (People & Auth endpoints)  
+**Default (Localhost):** `http://localhost:8001` (Account)

+
+## Changelog
+
+| Version | Date | Changes |
+|---------|------|----------|
+| 2.0 | December 26, 2025 | **BREAKING:** Converted all JSON properties from snake_case to camelCase to match C#/.NET implementation (e.g., `person_id` → `personId`, `first_name` → `firstName`). Query parameters also converted to camelCase. This matches ASP.NET Core default JSON serialization. |
+| 1.1 | December 23, 2025 | Migrated People endpoints from Traction service to Account service |
+| 1.0 | December 21, 2025 | Initial version |
+
+---
+
+## Overview
+
+The People module manages all person records within a tenant, including employees, consultants, vendors, and other stakeholders. This module also handles Person Types, Tags, and the User-Person linking that enables work item assignments.
+
+### Frontend Implementation
+
+- **Primary Client:** `accountClient` (axios instance) ⚠️ *Changed from tractionClient*
+- **Related Files:**
+  - `src/services/people-service.ts` - Person CRUD operations
+  - `src/services/person-types-service.ts` - Person type management
+  - `src/services/person-tags-service.ts` - Tag management
+
+### Key Concepts
+
+- **Person**: Any individual related to the business (may or may not have system access)
+- **User**: A Person with PurposePath login credentials
+- **PersonType**: Category defining relationship to business (Employee, Vendor, etc.)
+- **Tag**: Flexible label for grouping/filtering people
+- **Assignable**: Flag indicating if a person can receive work assignments
+
+### Email Verification
+
+A Person's `isEmailVerified` flag is set to `true` when:
+1. They accept a user invitation and create their account (primary flow)
+2. They complete email verification during password reset
+
+There is no explicit `POST /people/{id}/verify-email` endpoint. Email verification is implicitly handled through the user invitation acceptance flow.
+
+---
+
+## Authentication Changes
+
+### POST /auth/login
+
+User authentication with username/password.
+
+**⚠️ BREAKING CHANGE:** Login now uses `username` instead of `email`.
+
+**Request:**
+
+```json
+{
+  "username": "string",
+  "password": "string"
+}
+```
+
+**Field Constraints:**
+
+| Field | Type | Required | Constraints |
+|-------|------|----------|-------------|
+| username | string | Yes | 3-50 characters |
+| password | string | Yes | Min 8 characters |
+
+**Response:**
+
+```json
+{
+  "success": true,
+  "data": {
+    "accessToken": "string",
+    "refreshToken": "string",
+    "user": {
+      "userId": "string (GUID)",
+      "username": "string",
+      "personId": "string (GUID)",
+      "tenantId": "string (GUID)",
+      "avatarUrl": "string?",
+      "createdAt": "string (ISO 8601)",
+      "updatedAt": "string (ISO 8601)",
+      "status": "active | inactive | locked",
+      "preferences": {}
+    },
+    "person": {
+      "id": "string (GUID)",
+      "firstName": "string",
+      "lastName": "string",
+      "email": "string?",
+      "phone": "string?",
+      "title": "string?"
+    },
+    "tenant": {
+      "id": "string (GUID)",
+      "name": "string"
+    }
+  }
+}
+```
+
+**Error Responses:**
+
+```json
+{
+  "success": false,
+  "error": "Invalid username or password",
+  "code": "INVALID_CREDENTIALS"
+}
+```
+
+```json
+{
+  "success": false,
+  "error": "Account is locked",
+  "code": "ACCOUNT_LOCKED",
+  "details": {
+    "lockedUntil": "2025-12-22T10:30:00Z"
+  }
+}
+```
+
+**Frontend Handling:**
+
+- Stores `accessToken` → `localStorage.accessToken`
+- Stores `refreshToken` → `localStorage.refreshToken`
+- Stores `tenant.id` → `localStorage.tenantId`
+- Person data available for profile display
+
+---
+
+### POST /auth/forgot-username
+
+Request username reminder via email.
+
+**Request:**
+
+```json
+{
+  "email": "string"
+}
+```
+
+**Field Constraints:**
+
+| Field | Type | Required | Constraints |
+|-------|------|----------|-------------|
+| email | string | Yes | Valid email format |
+
+**Response (Always 200 to prevent email enumeration):**
+
+```json
+{
+  "success": true,
+  "message": "If the email is associated with any accounts, instructions have been sent."
+}
+```
+
+**Backend Behavior:**
+
+1. Find all Persons with verified email matching input
+2. For each Person linked to a User, include the username
+3. Send email listing all associated usernames and tenant names
+4. Always return success (even if email not found)
+
+---
+
+### PUT /user/username
+
+Change current user's username.
+
+**Headers Required:**
+

+**Request:**
+
+```json
+{
+  "newUsername": "string",
+  "currentPassword": "string"
+}
+```

+|-------|------|----------|-------------|
+| newUsername | string | Yes | 3-50 chars, alphanumeric + `.` `_` `-` `@`, must start with alphanumeric |
+| currentPassword | string | Yes | Current password for verification |
+
+**Response:**
+
+```json
+{
+  "success": true,
+  "data": {
+    "username": "string",
+    "previousUsername": "string",
+    "nextChangeAllowedAt": "string (ISO 8601)"
+  }
+}
+```
+
+**Error Responses:**
+
+```json
+{
+  "success": false,
+  "error": "Username is already taken",
+  "code": "DUPLICATE_RESOURCE",
+  "details": {
+    "field": "newUsername"
+  }
+}
+```
+
+```json
+{
+  "success": false,
+  "error": "Username can only be changed once every 30 days",
+  "code": "RATE_LIMIT_EXCEEDED",
+  "details": {
+    "nextChangeAllowedAt": "2025-01-15T10:30:00Z"

+}
+```
+
+```json
+{
+  "success": false,
+  "error": "Invalid current password",
+  "code": "INVALID_CREDENTIALS"
+}
+```
+

+# Traction Service API Specifications (v7)
+
+**Version:** 7.0  
+**Last Updated:** December 23, 2025  
+**Service Base URL:** `{REACT_APP_TRACTION_API_URL}`  
+**Default (Localhost):** `http://localhost:8002`
+
+[← Back to Main Index](../index.md)
+
+---
+
+## Overview
+
+This directory contains detailed API specifications for the Traction Service, organized by controller/feature area for easier maintenance and reference.
+
+**Version 7 Changes:**
+- Removed all deprecated GoalMeasureLink, MeasureMilestone, MeasureActual, and MeasureReading endpoints
+- Documented only actively implemented endpoints
+- Split large specification into maintainable controller-based documents
+- Updated to reflect MeasureLink and MeasureData design (Epic #362)
+
+---
+
+## Authentication & Headers
+
+**All endpoints require:**
+- `Authorization: Bearer {accessToken}` - JWT token from authentication
+- `X-Tenant-Id: {tenantId}` - Multi-tenancy identifier (UUID)
+
+**Optional headers:**
+- `X-Frontend-Base-Url` - Base URL for email links (used by some endpoints)
+
+---
+
+## API Structure
+
+### Controller-Based Specifications
+
+| Document | Controller | Endpoints | Description |
+|----------|------------|-----------|-------------|
+| [Goals API](./goals-api.md) | GoalsController | 11 endpoints | Goal lifecycle management |
+| [Strategies API](./strategies-api.md) | StrategiesController | 6 endpoints | Strategy management and alignment |
+| [Alignment API](./alignment-api.md) | AlignmentController | 1 endpoint | Cached goal alignment lookup |
+| [Measures API](./measures-api.md) | MeasuresController | 7 endpoints | Measure instance management |
+| [Measure Links API](./measure-links-api.md) | MeasureLinksController | 6 endpoints | Link Measures to goals, people, strategies |
+| [Measure Data API](./measure-data-api.md) | MeasureDataController | 8 endpoints | Targets, actuals, projections |

+
+> **Note:** People API has been deferred and moved to Account Service for better organizational alignment.
+
+### Reference Data APIs
+
+> **Note:** Reference data endpoints (issue types, statuses, tags) are integrated within their respective API documents above.
+
+---
+
+## Common Patterns
+
+### Response Structure
+
+All endpoints return a consistent wrapper:
+
+```json
+{
+  "success": true,
+  "data": { /* actual response data */ },
+  "error": null,
+  "timestamp": "2025-12-23T10:30:00Z"
+}
+```
+
+### Pagination
+
+List endpoints support pagination:
+
+**Query Parameters:**
+- `page` (number, default: 1) - Page number (1-indexed)
+- `pageSize` (number, default: 20) - Items per page
+- `sortBy` (string) - Field to sort by
+- `sortOrder` (string) - "asc" or "desc"
+
+**Paginated Response:**
+```json
+{
+  "success": true,
+  "data": {
+    "items": [ /* array of items */ ],
+    "pagination": {
+      "page": 1,
+      "pageSize": 20,
+      "total": 150,
+      "totalPages": 8
+    }
+  }
+}
+```
+
+### Error Responses
+
+```json
+{
+  "success": false,
+  "data": null,
+  "error": "Descriptive error message",
+  "timestamp": "2025-12-23T10:30:00Z"
+}
+```
+
+**HTTP Status Codes:**
+- `200` - Success
+- `201` - Created
+- `400` - Bad Request (validation errors)
+- `401` - Unauthorized (missing/invalid token)
+- `403` - Forbidden (insufficient permissions)
+- `404` - Not Found
+- `422` - Unprocessable Entity (business rule violation)
+- `500` - Internal Server Error
+
+### Date/Time Format
+
+All dates use ISO 8601 format: `YYYY-MM-DDTHH:mm:ss.fffZ`
+
+Example: `"2025-12-23T15:30:00.000Z"`
+
+### Field Naming
+
+- **Frontend:** camelCase (e.g., `goalName`, `createdAt`)
+- **Backend:** May use PascalCase internally but APIs use camelCase
+- **Enums:** lowercase with underscores (e.g., `in_progress`, `on_track`)
+

+
+## Quick Reference
+
+### Most Common Endpoints
+
+| Operation | Method | Endpoint |
+|-----------|--------|----------|
+| List goals | GET | `/goals` |
+| Create goal | POST | `/goals` |
+| Get goal details | GET | `/goals/{id}` |
+| Update goal | PUT | `/goals/{id}` |

+
+## Migration from v6
+
+**Removed Endpoints (Deprecated):**
+- All `/goals/{goalId}/measures:link` endpoints → Use `/measure-links` instead
+- All `/goals/{goalId}/measures:unlink` endpoints → Use `/measure-links` DELETE
+- All `/goals/{goalId}/available-measures` endpoints → New design pending
+- All `/measure-planning/*` endpoints → Redesigned as `/measure-data`
+- All shared Measure endpoints → Consolidated into `/measure-links`
+
+**New Endpoints (v7):**
+- `/measure-links` - Unified Measure linking
+- `/measure-data` - All Measure data operations (targets, actuals, projections)
+- Simplified Measure management
+
+**Changed Endpoints:**
+- Measure operations moved from goals context to dedicated Measure resources
+- More RESTful resource design
+
+---
+
+## Development Guidelines
+
+### Adding New Endpoints
+
+1. Update appropriate controller spec file
+2. Document request/response structures completely
+3. Include validation rules and constraints
+4. Add examples
+5. Update this index with endpoint count
+
+### Deprecating Endpoints
+
+1. Mark as deprecated in spec with migration path
+2. Add comment to controller code
+3. Update migration section in this README
+4. Plan removal timeline
+
+### Maintaining Specifications
+
+- Specs should match actual implementation
+- Update specs when code changes
+- Review specs during code review
+- Keep examples realistic
+
+---
+

+```
+
+#### Business Rules
+
+- **Default status:** New actions default to `not_started` status if not provided
+- **Default progress:** New actions default to 0% progress if not provided
+- **Completed actions:** If status is `completed`, progress is automatically set to 100% regardless of provided value
+- **Progress validation:** Progress must be between 0 and 100 (inclusive)
+- **Date validation:** `dueDate` must be after `startDate`
+- **Person validation:** `assignedPersonId` must exist in tenant
+- **Connections:** Goals, strategies, issues are linked after action creation
+- **Invalid connection IDs:** Invalid GUID formats are filtered out (action still created)

+
+## Notes
+
+- **RESTful Design**: Endpoints now follow RESTful conventions with resource IDs in URL paths
+- **Frontend Context**: Frontend always has `goalId` from goal creation/selection, eliminating need for intent-based lookups
+- **Performance**: Direct ID-based lookups are significantly faster than scanning and matching by intent string
+- **Simplicity**: No unnecessary business foundation payload in GET requests
+- **Breaking Change**: v7.2 removes deprecated `POST /alignment/check` and `POST /alignment/save` endpoints

+
+#### Measure Response Fields
+
+The `measures` array contains enriched measure data combining both MeasureLink and Measure properties:
+
+| Field | Type | Nullable | Description |
+|-------|------|----------|-------------|
+| **MeasureLink Properties** | | | |
+| `measureLinkId` | string (UUID) | No | Unique identifier for the measure-goal link |
+| `strategyId` | string (UUID) | Yes | Strategy this measure is linked to (null for goal-level measures) |
+| `isPrimary` | boolean | No | Whether this is the primary measure for the goal |
+| `thresholdPct` | number | Yes | Variance threshold percentage for alerts (0-100) |
+| `progressStatus` | string | Yes | Calculated status: "on_track", "at_risk", "behind" |
+| **Measure Properties** | | | |
+| `measureId` | string (UUID) | No | Unique identifier for the measure |
+| `name` | string | No | Measure name |
+| `unit` | string | No | Unit of measurement (e.g., "USD", "users", "%") |
+| `direction` | string | No | Expected direction: "up", "down", "maintain" |
+| `currentValue` | number | Yes | Current/latest measured value |
+| `targetValue` | number | Yes | (Deprecated) Target value - now stored separately |
+| `progress` | number | Yes | Progress percentage toward target (calculated separately) |
+| `variance` | number | Yes | Difference from target (calculated separately) |
+| `category` | string | Yes | Business category (e.g., "revenue", "growth", "efficiency") |
+| `catalogId` | string (UUID) | Yes | Reference to measure catalog entry |
+| `aggregationType` | string | Yes | How values aggregate: "sum", "average", "count", "min", "max", "latest", "point_in_time" |
+| `aggregationPeriod` | string | Yes | Time period: "daily", "weekly", "monthly", "quarterly", "yearly" |
+| `type` | string | No | Input type: "quantitative" (numeric), "qualitative" (options), "binary" (yes/no) |
+| `ownerId` | string (UUID) | Yes | Measure owner - the person responsible for this measure |
+
+**Note:** `progress`, `variance`, and `progressStatus` are calculated from measure targets and actuals using the domain progress calculation service (same as the measures endpoint). `targetValue` remains `null` as targets are stored separately in the system. `progressStatus` reflects the calculated status relative to link thresholds ("on_track", "at_risk", "behind"). If insufficient data exists for a measure (less than 2 actuals or no target), these fields will be `null`.
+
+---
+
+### 4. Update Goal
+
+**PUT** `/goals/{id}`
+
+Update an existing goal's properties.
+
+#### Path Parameters
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `id` | string (UUID) | Goal identifier |
+
+#### Request Body
+
+```json
+{
+  "name": "Increase Revenue by 30%",
+  "description": "Updated target to 30% growth",
+  "targetDate": "2025-12-31T23:59:59.999Z",
+  "ownerId": "user-456"
+}
+```
+
+#### Request Fields
+
+All fields are optional (only include fields to update):
+
+| Field | Type | Constraints | Description |
+|-------|------|-------------|-------------|
+| `name` | string | 1-200 chars | Goal name |
+| `description` | string | Max 2000 chars | Description |
+| `type` | string | See enum | Goal type |
+| `targetDate` | string (ISO 8601) | Future date | Target date |
+| `startDate` | string (ISO 8601) | - | Start date |
+| `ownerId` | string (UUID) | Must exist | Owner ID |
+
+**Note:** Status is updated via dedicated endpoints (activate, pause, close)
+
+#### Owner Change Propagation
+
+When the `ownerId` field is updated, the system automatically propagates the ownership change to related entities following the **unified measure ownership model**:
+
+**Propagation Logic:**
+1. System identifies all Measures linked to this goal
+2. For each Measure where `Measure.OwnerId` equals the goal's **previous owner**:
+   - Updates `Measure.OwnerId` to the new owner
+   - Fetches **ALL MeasureLinks** for that Measure (across all goals and strategies)
+   - Updates `MeasureLink.personId` to the new owner for every link
+
+**Example Scenario:**
+```
+Initial State:
+- Goal A (owner: Alice)
+- Measure M1 (owner: Alice) linked to Goal A
+- MeasureLinks: Link1→Goal A, Link2→Goal B, Link3→Strategy S1 (all with personId: Alice)
+
+After updating Goal A owner to Bob:
+- Goal A (owner: Bob)
+- Measure M1 (owner: Bob) - UPDATED because it matched old owner
+- MeasureLinks: Link1, Link2, Link3 (all with personId: Bob) - ALL updated
+
+If Measure M2 had a different owner (Charlie), it would NOT be affected.
+```
+
+**Key Behaviors:**
+- ✅ Only affects Measures that were owned by the previous goal owner
+- ✅ Updates ALL links for affected Measures (maintains unified ownership)
+- ✅ Preserves explicitly assigned owners (Measures not matching old owner remain unchanged)
+- ✅ Handles multi-goal scenarios correctly (Measure linked to multiple goals)
+- ✅ Operation is atomic and logged for audit purposes
+
+**Logging:** The operation logs:
+- Number of Measures updated
+- Number of MeasureLinks updated
+- Individual Measure updates with owner transition details

+
+### v7.1 (December 27, 2025)
+- **Restored** `/goals/{goalId}/available-measures` endpoint (Issue #413)
+- Updated to work with new `IMeasureLinkRepository` architecture

+# Coaching Insights API
+
+**Service:** Traction Service (.NET)  
+**Controller:** InsightsController  
+**Version:** v1.0  
+**Last Updated:** February 4, 2026
+
+## Overview
+
+The Coaching Insights API manages AI-generated coaching insights and recommendations. Insights are generated by the Python Coaching Service and persisted in the Traction Service for retrieval and management.
+
+**Architecture Flow:**
+1. Frontend calls Python Coaching Service `POST /insights/generate` (documented in [coaching-service.md](../coaching-service.md))
+2. Python AI returns insights with snake_case properties (kiss_category, alignment_impact, etc.)
+3. Frontend persists to Traction Service `POST /traction/api/v1/insights/batch` (snake_case accepted via JsonPropertyName)
+4. C# API returns camelCase properties (kissCategory, alignmentImpact, etc.) - standard .NET convention
+5. Widget retrieves via dashboard endpoint (documented in [dashboard-service.md](../dashboard-service.md#ai-insights-widget))
+

+# Issues API Specification
+
+**Service:** Traction Service  
+**Base Path:** `/api/issues`  
+**Version:** v7.1  
+**Last Updated:** January 4, 2026
+
+## Overview
+
+The Issues API manages operational issues, bugs, blockers, and problems within the PurposePath system. Unlike Goals or Actions, Issues represent problems that need resolution rather than outcomes or tasks. Issues support configurable types and statuses, impact/priority tracking, lifecycle management, and can be converted into actionable items.
+
+### Key Features
+
+- **Configurable Status & Types**: Uses `IssueStatusConfigId` and `IssueTypeConfigId` for tenant-customizable workflows
+- **Lifecycle Management**: Start, resolve, close, and reopen issues with specific endpoints
+- **Impact & Priority Tracking**: Separate dimensions for business impact vs urgency
+- **Tag-Based Organization**: Add/remove tags for flexible categorization
+- **Relationship Management**: Link to goals, strategies, and actions
+- **Issue Conversion**: Convert issues into one or more actions
+- **Statistics Dashboard**: Aggregated metrics by status, type, impact, and timeline
+
+### Design Notes
+
+- **Configuration-Based Status/Types**: Unlike other APIs using simple enums, Issues use configurable status and type systems
+- **Lifecycle Endpoints**: Dedicated endpoints for state transitions (start, resolve, close, reopen) ensure proper workflow
+- **Bug-Specific Fields**: Includes environment, steps to reproduce, expected/actual behavior for bug tracking
+- **Comma-Separated OR Filtering**: Priority and impact support OR logic (e.g., "high,critical")

+### Enumerations
+
+```typescript
+// IssueImpact - Business impact level
+enum IssueImpact {
+  Low = 'low',
+  Medium = 'medium',
+  High = 'high',
+  Critical = 'critical'
+}
+
+// Priority - Urgency level (same as Actions)
+enum Priority {
+  Low = 'low',
+  Medium = 'medium',
+  High = 'high',
+  Critical = 'critical'
+}
+```
+
+**Impact vs Priority**: 
+- **Impact**: Business consequence if unresolved (data loss = high, typo = low)
+- **Priority**: Time urgency (blocking production = critical, nice-to-have = low)

+
+## Migration Notes from v6
+
+### Configuration-Based Status & Types
+
+**v6 (Simple Enums)**
+```typescript
+// Old approach used hardcoded status/type enums
+status: 'open' | 'in_progress' | 'resolved' | 'closed'
+type: 'bug' | 'feature' | 'task'
+```
+
+**v7 (Configuration-Based)**
+```typescript
+// New approach uses configurable status and type systems
+statusConfigId: string;   // UUID referencing IssueStatusConfig
+typeConfigId: string;     // UUID referencing IssueTypeConfig
+
+// Each tenant can define custom statuses and types
+// Status configs include: id, name, category, displayOrder, isDefault
+// Type configs include: id, name, description, icon, color
+```
+
+**Migration Impact**: Frontend must fetch status/type configurations separately and use IDs in requests instead of hardcoded enum values.
+
+### Lifecycle Endpoints
+
+**v6**: Single `/status` endpoint for all status changes
+
+**v7**: Dedicated endpoints for specific transitions
+- `PUT /issues/{id}/start` - Start work
+- `PUT /issues/{id}/resolve` - Mark resolved
+- `PUT /issues/{id}/close` - Close issue
+- `PUT /issues/{id}/reopen` - Reopen issue
+- `PUT /issues/{id}/status` - Generic status change
+
+**Migration Strategy**: Use specific lifecycle endpoints for better semantics and validation. Generic `/status` endpoint still available for custom workflows.
+
+### Tag Management Optimization
+
+**v6**: Single-tag add/remove operations
+
+**v7**: Batch tag operations
+- `PUT /issues/{id}/tags` with array - Add multiple tags atomically
+- `DELETE /issues/{id}/tags` with array - Remove multiple tags atomically
+
+**Migration Strategy**: Update frontend to send tag arrays instead of individual tags for better performance.
+
+### Issue Conversion Feature
+
+**New in v7**: `POST /issues/{issueId}/convert-to-actions`
+
+Enables breaking down complex issues into actionable work items with automatic connection inheritance. Not available in v6.
+
+---
+
+## Related APIs
+
+- **[Actions API](./actions-api.md)**: Created from issue conversion
+- **[Goals API](./goals-api.md)**: Issue connections to goals
+- **People API** (coming): Reporter and assignee details
+- **Configuration API** (coming): IssueStatusConfig and IssueTypeConfig management
+
+---
+
+## Changelog
+
+### v7.1 (January 4, 2026)
+- **NEW**: Reorder issues endpoint (`PUT /issues:reorder`) for drag-and-drop sorting support
+  - Updates `displayOrder` field based on array position
+  - Supports atomic batch updates in single transaction
+  - Similar pattern to issue-statuses:reorder endpoint
+
+### v7.0 (December 23, 2025)
+- **NEW**: Configuration-based status and types replacing hardcoded enums
+- **NEW**: Dedicated lifecycle endpoints (start, resolve, close, reopen)
+- **NEW**: Batch tag management (add/remove multiple tags atomically)
+- **NEW**: Issue conversion to actions with inheritance
+- **NEW**: Comprehensive filtering with comma-separated OR logic for priority/impact
+- **NEW**: Issue statistics endpoint with type, impact, and timeline breakdowns
+- **IMPROVED**: Bug-specific fields (environment, steps to reproduce, expected/actual behavior)
+- **IMPROVED**: Root cause analysis and resolution notes tracking
+- **CHANGED**: Status and type now use config IDs instead of enum strings
+
+---
+
+## TODO / Known Limitations
+
+1. **Status Config Lookup**: Current implementation has placeholder for tenant default status config lookups (start, resolve, close, reopen endpoints)
+2. **Relationship Endpoints**: Not yet implemented (coming soon):
+   - `PUT /api/issues/{issueId}/goals`
+   - `PUT /api/issues/{issueId}/strategies`
+   - `PUT /api/issues/{issueId}/actions`
+   - `DELETE /api/issues/{issueId}/relationships`
+3. **Status Configuration Management**: Separate API needed for managing IssueStatusConfig and IssueTypeConfig entities
+4. **Workflow Validation**: Status transition rules not yet enforced (e.g., can't resolve without being in-progress)

+# Measure Data API Specification
+
+**Version:** 9.0  
+**Last Updated:** January 8, 2026  
+**Base Path:** `/measures/{measureId}`  
+**Controller:** `MeasureDataController.cs`
+
+## ⚠️ BREAKING CHANGES (v9.0 - Issue #557)
+
+**Released:** January 8, 2026  
+**GitHub Issue:** [#557 - Fix MeasureData Architecture](https://github.com/purposepath/purposepath-api/issues/557)
+
+### Overview
+Version 9.0 introduces a significant architectural improvement where Measure Data is now tied directly to Measures instead of MeasureLinks. This fixes the data model inconsistency where the same measure with multiple links had separate data sets.
+
+### URL Changes (REQUIRED UPDATE)
+All endpoints have changed from `/measures/{measureId}/*` to `/measures/{measureId}/*`:
+
+| Old Endpoint (v8) | New Endpoint (v9) |
+|-------------------|-------------------|
+| `GET /measures/{measureId}/targets` | `GET /measures/{measureId}/targets` |
+| `POST /measures/{measureId}/targets` | `POST /measures/{measureId}/targets` |
+| `PUT /measures/{measureId}/targets/{targetId}` | `PUT /measures/{measureId}/targets/{targetId}` |
+| `DELETE /measures/{measureId}/targets/{targetId}` | `DELETE /measures/{measureId}/targets/{targetId}` |
+| `GET /measures/{measureId}/actuals` | `GET /measures/{measureId}/actuals` |
+| `POST /measures/{measureId}/actuals` | `POST /measures/{measureId}/actuals` |
+| `PUT /measures/{measureId}/actuals/{actualId}/override` | `PUT /measures/{measureId}/actuals/{actualId}/override` |
+| `DELETE /measures/{measureId}/actuals/{actualId}` | `DELETE /measures/{measureId}/actuals/{actualId}` |
+| `GET /measures/{measureId}/all-series` | `GET /measures/{measureId}/all-series` |
+
+### Response Field Changes (REQUIRED UPDATE)
+All response DTOs now use `measureId` instead of `measureLinkId`:
+
+```json
+// ❌ Old (v8)
+{
+  "measureId": "measure-456",
+  "targets": [...]
+}
+
+// ✅ New (v9)
+{
+  "measureId": "measure-456",
+  "targets": [...]
+}
+```
+
+### Migration Guide for Frontend Developers
+
+#### Step 1: Update API Service Base URLs
+```typescript
+// ❌ Old
+const url = `/measure-links/${linkId}/targets`;
+
+// ✅ New - Get measureId from link object
+const url = `/measures/${link.measureId}/targets`;
+```
+
+#### Step 2: Update Response Type Definitions
+```typescript
+// ❌ Old interface
+interface MeasureDataResponse {
+  measureLinkId: string;
+  targets: TargetValue[];
+  actuals: ActualValue[];
+}
+
+// ✅ New interface
+interface MeasureDataResponse {
+  measureId: string;  // Changed from measureLinkId
+  targets: TargetValue[];
+  actuals: ActualValue[];
+}
+```
+
+#### Step 3: Update Component Props
+```typescript
+// ❌ Old
+function MeasureChart({ measureLinkId }: Props) {
+  const data = await fetchMeasureData(measureLinkId);
+}
+
+// ✅ New
+function MeasureChart({ measureId }: Props) {
+  const data = await fetchMeasureData(measureId);
+}
+```
+
+#### Step 4: Accessing measureId from Link Objects
+```typescript
+// All MeasureLink objects now have a measureId property
+const link = await getMeasureLink(linkId);
+const data = await fetchMeasureData(link.measureId);  // Use this
+```
+
+### Data Persistence Changes
+- DynamoDB partition keys changed from `MEASURELINK#{linkId}` to `MEASURE#{measureId}`
+- GSI names changed: `measure-link-index` → `measure-index`
+- All measure data is now stored once per Measure (not per Link)
+- Multiple links to the same Measure share the same data set
+
+### Benefits of This Change
+✅ **Architectural correctness:** Data properly tied to the Measure entity  
+✅ **Data consistency:** One Measure = one data set, regardless of links  
+✅ **Simplified queries:** No need to aggregate across multiple links  
+✅ **Widget performance:** Widgets query by measureId directly  
+
+### Backward Compatibility
+⚠️ **None** - This is a breaking change requiring frontend updates  
+⚠️ All old `/measures/{measureId}/*` endpoints will return 404  
+⚠️ All `measureLinkId` fields in responses have been removed  
+
+**Estimated Frontend Migration Time:** 1-2 days for a typical application
+
+---
+
+## Overview
+
+The Measure Data API manages target values and actual measurements for Measures. This is the v9 architecture where data is tied directly to Measures (not MeasureLinks), consolidated with v8 data model that unifies Expected/Optimal/Minimal targets into a single record (issue #512, #557).
+
+### Key Features
+- **Measure-scoped:** All data is associated with a Measure (not MeasureLink)
+- **Consolidated Targets:** Set expected, optimal, and minimal values in a single record
+- **Actuals:** Record measured values and estimates
+- **Time-series data:** Track Measure progress over time
+- **Override support:** Manual corrections with audit trail
+- **Combined queries:** Get all targets + actuals in one request
+
+### Design Philosophy
+- **Single record per target date:** Expected/Optimal/Minimal values stored together, not as separate records
+- **Measure-scoped:** All data is associated with a Measure directly (architectural fix in v9)
+- **Category-based:** `Target` (with optional optimal/minimal) or `Actual` (Measured/Estimate)
+- **Historical tracking:** All values are preserved with timestamps
+- **Simplified validation:** Three-value consistency enforced: `OptimalValue >= PostValue >= MinimalValue`
+
+---
+
+## Authentication
+
+All endpoints require:
+- `Authorization: Bearer {accessToken}`
+- `X-Tenant-Id: {tenantId}`
+
+---
+

+---
+
+## Data Models
+
+### Data Category Enum
+
+```typescript
+enum DataCategory {
+  Target = "Target",  // Target values
+  Actual = "Actual"   // Actual measurements
+}
+```
+
+### Actual Subtype Enum
+
+```typescript
+enum ActualSubtype {
+  Measured = "Measured",  // Actual measured value
+  Estimate = "Estimate"   // Projected/estimated value
+}
+```
+
+### Data Source Enum
+
+```typescript
+enum DataSource {
+  Manual = "Manual",           // Manually entered
+  Automated = "Automated",     // Automated sync/import
+  Integration = "Integration"  // External system integration
+}
+```
+
+---
+
+## Business Rules
+
+### Targets
+
+1. **Consolidated record:** Expected (primary), Optimal (stretch), and Minimal (floor) values stored in single record
+2. **Required field:** `postValue` (expected) is always required for targets
+3. **Optional fields:** `optimalValue` and `minimalValue` are optional
+4. **Value validation:** When both optimalValue and minimalValue provided: `optimalValue >= postValue >= minimalValue`
+5. **Time-series:** Can have multiple target entries for different future dates
+6. **Confidence level:** Optional 0-100 value indicating certainty about achieving the target
+7. **Rationale:** Recommended to document why a target was set at a specific value
+
+### Actuals
+
+1. **Historical preservation:** All actuals are kept for historical analysis
+2. **Measured vs Estimate:**
+   - Use `Measured` for confirmed values from data sources
+   - Use `Estimate` for projections or manual estimates
+3. **Override capability:** Can correct values with audit trail (original value + comment)
+4. **Data source tracking:** Records where data came from and reference ID

+
+## Error Handling
+
+### Standard Error Response

+## Migration from v6
+
+### Deprecated Entities (Removed in v7)
+
+| Old Entity (v6) | New Entity (v7) | Notes |
+|-----------------|-----------------|-------|
+| `MeasureMilestone` | `MeasureData` (Target subtype) | Unified into single entity |
+| `MeasureActual` | `MeasureData` (Actual subtype) | Unified into single entity |
+| `MeasureReading` | `MeasureData` (Actual subtype) | Merged with MeasureActual |
+
+### Key Differences
+
+**v6 (Separate entities):**
+- `MeasureMilestone` for target values
+- `MeasureActual` for measured values
+- `MeasureReading` for estimates
+- Different endpoints for each type
+
+**v7 (Unified model):**
+- Single `MeasureData` entity with `DataCategory` (Target/Actual)
+- Target subtypes: Expected/Optimal/Minimal
+- Actual subtypes: Measured/Estimate
+- Consistent endpoints: `/measures/{measureId}/targets` and `/measures/{measureId}/actuals`
+
+### Benefits of v7 Design
+
+- ✅ Single entity reduces complexity
+- ✅ Consistent API patterns
+- ✅ Easier querying (all data in one table)
+- ✅ Better time-series support
+- ✅ Unified audit trail

+# Measure Links API Specification
+
+**Version:** 8.4  
+**Last Updated:** January 15, 2026  
+**Base Path:** `/measure-links`  
+**Controller:** `MeasureLinksController.cs`
+
+## Overview
+
+The Measure Links API manages relationships between Measures and entities (persons, goals, strategies). Every Measure link requires a person (owner/responsible party) and can optionally be associated with a goal and/or strategy.
+
+### Key Features
+- Link Measures to persons (required), with optional goal and strategy associations
+- Configure thresholds, weights, and display order for each link
+- Mark primary Measures for goals
+- Query Measure links with flexible filtering (by person, goal, strategy, or Measure)
+- Update or remove links
+- Automatic cascade delete when tenant-specific Measures are deleted
+
+### Design Philosophy
+- **Unified resource-based API:** All Measure link operations through `/measure-links` endpoints
+- **Person-centric:** Every Measure link must have a person (owner)
+- **Flexible filtering:** Query by any entity type (person, goal, strategy, Measure) with optional `includeAll` parameter
+- **Derived linkType:** Link type is calculated based on foreign key presence (not persisted)
+- **Multi-entity:** One Measure can be linked to multiple persons/goals/strategies simultaneously
+
+---
+
+## Authentication
+
+All endpoints require:
+- `Authorization: Bearer {accessToken}`
+- `X-Tenant-Id: {tenantId}`
+
+---

+
+#### Business Rules
+
+- **Person Required:** PersonId must always be provided
+- **Strategy Requires Goal:** If strategyId is provided, goalId must also be provided
+- **Entity Validation:** All referenced entities (Measure, person, goal, strategy) must exist in tenant
+- **Duplicate Prevention:** Cannot create duplicate links (same Measure + person + goal + strategy combination)
+- **Auto linkType:** Calculated automatically: `personal` (no goal/strategy), `goal` (has goalId), `strategy` (has goalId + strategyId)
+- **Primary Measure:** Setting isPrimary=true may unset other primary Measures for the same goal
+
+---
+
+### 3. Update Measure Link
+
+Update link configuration (person, goal, strategy, threshold, weight, priority, etc.).
+
+**Endpoint:** `PUT /measure-links/{linkId}`
+
+#### Path Parameters
+
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `linkId` | string (GUID) | **Yes** | Measure link identifier |
+
+#### Request Body
+
+```json
+{
+  "personId": "person-789e1234-e89b-12d3-a456-426614174002",
+  "goalId": "goal-012e3456-e89b-12d3-a456-426614174003",
+  "strategyId": "strategy-345e6789-e89b-12d3-a456-426614174004",
+  "thresholdPct": 85.0,
+  "riskThresholdPct": 50.0,
+  "weight": 2.0,
+  "displayOrder": 1,
+  "isPrimary": true
+}
+```
+
+#### Request Fields
+
+All fields are optional. Only provided fields will be updated.
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `personId` | string (GUID) | Person responsible for this link. **When changed, propagates to the Measure and all other links for that Measure.** |
+| `goalId` | string (GUID) or null | Goal association. Omitted = no change; value = set/change goal; explicit null = remove goal. When goal is explicitly removed and `strategyId` is omitted, strategy is auto-removed. |
+| `strategyId` | string (GUID) or null | Strategy association. Omitted = no change; value = set/change strategy; explicit null = remove strategy. Requires a goal to be set after update. |
+| `thresholdPct` | decimal | Threshold percentage (0-100) |
+| `riskThresholdPct` | decimal | Risk threshold percentage (0-100) |
+| `weight` | decimal | Relative weight/importance |
+| `displayOrder` | int | Sort order in UI |
+| `isPrimary` | boolean | Mark as primary Measure |
+
+**Notes:** 
+- You cannot change `measureId` via update. Delete and recreate the link instead.
+- `linkType` is a calculated field and cannot be provided in requests. It is automatically derived from the presence of `goalId` and `strategyId`.
+- **PersonId Propagation:** When `personId` is updated, the change propagates to:
+  - The Measure's `ownerId` field
+  - All other MeasureLinks associated with the same Measure
+- **Strategy Validation:** When `strategyId` is provided, the system validates that:
+  - A `goalId` is set (either in the request or already on the link)
+  - The strategy exists and belongs to the specified goal
+- **Null vs Omitted Semantics (Issue #663):** For `goalId` and `strategyId` updates:
+  - **Omitted field**: existing value is preserved
+  - **Provided value**: association is updated
+  - **Provided as `null`**: association is explicitly removed
+
+#### Response
+

+    "linkedAt": "2025-12-20T10:00:00Z"
+  },
+  "error": null
+}
+```
+
+#### Business Rules
+
+- **Partial Updates:** Only provided fields are updated
+- **PersonId Propagation:** Updating `personId` cascades to Measure and all related links atomically
+- **Goal Association:** Can be set or changed; removing goal also removes strategy
+- **Strategy Validation:** 
+  - Strategy requires a goal to be present
+  - Strategy must belong to the specified goal
+  - System validates strategy-goal relationship before update
+- **Primary Measure:** Setting `isPrimary: true` may unset other primary Measures for the same goal
+- **Threshold Range:** Must be between 0 and 100 if provided
+- **Risk Threshold Range:** Must be between 0 and 100 if provided and must be <= thresholdPct
+- **Display Order:** Used for UI sorting, can be any positive integer
+- **Calculated linkType:** Automatically derived from `goalId` and `strategyId` presence - cannot be set via API

+### 4. Delete Measure Link
+
+Remove a Measure link.
+
+**Endpoint:** `DELETE /measure-links/{linkId}`
+
+#### Path Parameters
+
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `linkId` | string (GUID) | **Yes** | Measure link identifier |
+
+#### Request Example
+
+```http
+DELETE /measure-links/link-123e4567-e89b-12d3-a456-426614174000
+Authorization: Bearer {token}
+X-Tenant-Id: {tenantId}
+```
+
+#### Response
+
+**Status:** `200 OK`
+
+```json
+{
+  "success": true,
+  "data": {
+    "message": "Measure link deleted successfully",
+    "warning": null
+  },
+  "error": null
+}
+```
+
+**Status:** `200 OK` (with warning when last link)
+
+```json
+{
+  "success": true,
+  "data": {
+    "message": "Measure link deleted successfully",
+    "warning": "This was the last link for Measure 'Customer Satisfaction Score'. The Measure is now orphaned and cannot be managed. Consider deleting the Measure if no longer needed."
+  },
+  "error": null
+}
+```
+
+#### Business Rules
+
+- **No Cascade:** Does not delete the Measure, goal, or any related data
+- **Orphaned Measure Warning:** If this is the last link for a tenant-specific Measure, a warning is returned suggesting Measure deletion
+- **Primary Status:** If deleted link was primary, goal has no primary Measure until another is set
+- **Targets/Actuals Preserved:** Measure target and actual data remain intact (not deleted with link)

+
+**Note:** The query response includes denormalized fields for convenience:
+- `measureName` - Name of the linked Measure
+- `unit` - Unit of measurement
+- `personName` - Name of the responsible person
+- `goalTitle` - Title/name of the linked goal (if any) - **Issue #569**
+- `strategyTitle` - Title/name of the linked strategy (if any) - **Issue #569**
+- `currentValue` - Latest actual value (if any)
+- `currentValueDate` - Date of the latest actual value (if any)
+- `progress` - Progress calculation (Issue #527)
+- `measure` - Enriched measure details (only when `measureInfo=true`) - **Issue #562**
+  - `measurementConfig.aggregationPeriod` - Aggregation period ('daily', 'weekly', 'monthly', 'quarterly', 'yearly')
+  - `ownerId` - Person responsible for the measure
+  - `ownerName` - Owner's display name (denormalized)
+  - `ownerEmail` - Owner's email (denormalized)
+  - `trendData` - Array of recent data points (5-10 points) for sparkline visualization
+  - `metadata` - Audit information (createdAt, updatedAt)
+
+#### Use Cases
+
+- **Personal scorecards:** `?personId={id}` - Show person's personal Measures
+- **Person workload:** `?personId={id}&includeAll=true` - All Measures assigned to person
+- **Goal tracking:** `?goalId={id}` - Goal-level Measures only
+- **Goal cascade:** `?goalId={id}&includeAll=true` - Goal + strategy Measures
+- **Strategy metrics:** `?strategyId={id}` - All Measures for a strategy
+- **Cross-functional Measures:** `?measureId={id}` - Where is this Measure used?
+- **Person-goal assignment:** `?personId={id}&goalId={id}` - Person's work on specific goal
+
+---
+
+## Cascade Delete Behavior
+
+When a tenant-specific Measure is deleted via `DELETE /measures/{measureId}`, the following cascade deletions occur automatically:
+
+1. **Measure Links:** All links to this Measure are deleted
+2. **Measure Targets:** All target data for this Measure is deleted
+3. **Measure Actuals:** All actual measurement data for this Measure is deleted
+
+**Note:** This cascade only applies to tenant-specific Measures. Catalog Measures cannot be deleted by users.
+
+**Warning:** Cascade delete is permanent and cannot be undone. Ensure proper confirmation before deleting Measures.
+
+---
+
+## Data Models
+
+### Link Type (Calculated Field)
+
+```typescript
+type LinkType = "personal" | "goal" | "strategy";
+```
+
+**Calculation Logic:**
+- **personal:** Only `personId` is set (no `goalId` or `strategyId`)
+- **goal:** `personId` + `goalId` are set (no `strategyId`)
+- **strategy:** `personId` + `goalId` + `strategyId` are all set
+
+**Important:** `linkType` is NOT persisted in the database. It is calculated on-the-fly based on the presence of foreign keys. Do not include it in POST/PUT request bodies.
+
+### Threshold Percentage
+
+- **Range:** 0 - 100
+- **Meaning:** Completion threshold for the Measure (e.g., 80% = "on track" at 80% of target)
+- **Usage:** UI can show red/yellow/green status based on `currentValue` vs `targetValue` at threshold
+
+### Risk Threshold Percentage
+
+- **Range:** 0 - 100 (must be ≤ `thresholdPct`)
+- **Meaning:** Risk threshold for "at risk" status (e.g., 50% = "at risk" when variance percentage < -50)
+- **Usage:** Determines split between "behind" and "at_risk" statuses
+
+### Weight
+
+- **Range:** 0.0 - 1.0
+- **Meaning:** Relative importance for weighted calculations (normalized)
+- **Default:** 1.0 (but must be within 0.0-1.0 range)
+- **Validation:** Domain enforces 0.0 ≤ weight ≤ 1.0
+- **Usage:** When calculating weighted averages of multiple Measures
+
+### Display Order
+
+- **Range:** Any positive integer
+- **Meaning:** Sort order in UI (ascending)
+- **Usage:** Controls how Measures are listed on scorecards/dashboards
+
+---
+
+## Business Rules
+
+### Link Creation
+
+1. **Entity Validation:** All referenced entities (Measure, person, goal, strategy) must exist in tenant
+2. **Duplicate Prevention:** Cannot create duplicate links (same Measure + same person + same goal + same strategy)
+3. **Strategy Requires Goal:** Cannot link to strategy without also linking to goal
+4. **Person Required:** Every link must have a person (owner)
+
+### Primary Measure
+
+1. **Goal Scope:** Primary flag only applies when goalId is present
+2. **Single Primary:** Only one Measure can be primary per goal
+3. **Auto-Unset:** Setting isPrimary=true on one link may automatically set isPrimary=false on other links for the same goal
+
+### Delete Behavior
+
+1. **Link Deletion:** Removing a link does NOT delete the Measure or any entities
+2. **Orphan Warning:** If last link is deleted for a tenant-specific Measure, system warns about orphaned Measure
+3. **Cascade Delete:** Only `DELETE /measures/{id}` triggers cascade (links, targets, actuals)
+
+---
+
+## Error Handling
+
+### Standard Error Response
+
+```json
+{
+  "success": false,
+  "data": null,
+  "error": "Error message describing what went wrong"
+}
+```
+
+### Common Error Codes
+
+| Status Code | Scenario | Error Message |
+|-------------|----------|---------------|
+| `400` | Invalid GUID format | "Invalid link ID format" |
+| `400` | Missing required field | "PersonId is required" |
+| `400` | Strategy without goal | "Strategy link requires goalId" |
+| `400` | Duplicate link | "Measure link already exists" |
+| `404` | Link not found | "Measure link not found" |
+| `404` | Referenced entity not found | "Measure not found" |
+| `422` | Validation failed | "Threshold percentage must be between 0 and 100" |

+## Changelog
+
+### v8.3 (January 15, 2026) - Issue #569: Goal and Strategy Titles
+- ✨ **Added:** `goalTitle` and `strategyTitle` fields to all Measure Link response payloads
+- 🚀 **Performance:** Reduces frontend API calls by providing denormalized goal/strategy names directly in responses
+- 📝 **Implementation:** Query handler fetches and populates titles with throttled parallelism (max 10 concurrent)
+- 🔧 **Nullable fields:** Both fields return `null` when goal/strategy is not linked to the Measure Link
+
+### v8.2 (January 10, 2026) - Issue #527: Progress Calculation
+- ✨ **Added:** `progress` field to all measure link responses (GET /measure-links, GET /measure-links/{id})
+- 📊 Progress calculation includes: progressPercentage, status (on_track/at_risk/behind/no_data), variance, variancePercentage, daysUntilTarget, isOverdue
+- 🧮 Implemented via domain service pattern (`MeasureLinkProgressService`) following DDD principles
+- 📝 Progress calculated based on latest target and actual values, accounting for measure direction and threshold
+- 🚀 Batch optimization with throttled parallelism (max 10 concurrent) for performance
+
+### v8.1 (January 8, 2026)
+- 📝 **Updated:** Weight range clarified to 0.0-1.0 (matches domain validation)
+- ✨ **Added:** Query response includes denormalized fields: `measureName`, `unit`, `personName`, `currentValue`, `currentValueDate`
+- 📝 **Documentation:** Updated all examples to reflect actual implementation with denormalized fields
+- 🔧 **Clarification:** Weight validation enforces 0.0 ≤ weight ≤ 1.0 in domain layer
+
+### v8.0 (December 26, 2025)
+- 🔄 **BREAKING:** Unified Measure Links API - removed separate controllers
+- ❌ **Removed:** `PersonalMeasuresController` endpoints (`POST /people/{personId}/measures:link`, `POST /people/{personId}/measures:unlink`, `GET /people/{personId}/measures`)
+- ❌ **Removed:** `StrategyMeasuresController` endpoints (`GET /strategies/{strategyId}/measures`)
+- ✨ **Added:** `POST /measure-links` - unified endpoint for creating all link types
+- ✨ **Added:** `GET /measure-links` with query parameters - flexible filtering by measureId, personId, goalId, strategyId
+- ✨ **Added:** `includeAll` query parameter for nested link retrieval
+- 🔄 **Changed:** `linkType` is now a calculated/derived field (not persisted, not accepted in requests)
+- ✨ **Added:** Cascade delete behavior when Measures are deleted
+- ✨ **Added:** Orphaned Measure warning when last link is deleted
+- 📝 **Documentation:** Complete v8 specification with 5 unified endpoints
+
+### v7.0 (December 23, 2025)
+- ✨ New MeasureLink design replacing GoalMeasureLink (Issue #374)
+- ✅ Documented 8 endpoints across 3 controllers
+- ✨ Added personal scorecard endpoints (`/people/{personId}/measures`)
+- ✨ Added strategy Measure endpoints (`/strategies/{strategyId}/measures`)

+# Measures API Specification
+
+**Version:** 7.3  
+**Last Updated:** January 9, 2026  
+**Base Path:** `/measures`  
+**Controller:** `MeasuresController.cs`
+
+## Overview
+
+The Measures API manages Key Performance Indicators (Measures) within the PurposePath system. Measures measure progress toward strategies and goals, supporting both catalog-based Measures (from the Measure library) and custom user-defined Measures.
+
+### Key Features
+- List Measures with filtering by owner, goal, or strategy
+- Create catalog-based or custom Measures
+- Update Measure details or current values
+- Soft delete Measures (preserves historical data)
+- Query Measure-goal relationships
+- Retrieve Measures catalog for designing a new goal (no goalId required)
+- Retrieve Measure catalog for new (unpersisted) goals
+
+---
+
+## Authentication
+
+All endpoints require:
+- `Authorization: Bearer {accessToken}`
+- `X-Tenant-Id: {tenantId}`
+
+---
+
+## Endpoints
+
+### 0. Get Measure Summary
+
+**NEW** Issue #526
+
+Retrieve comprehensive MEASURE summary with filtering, aggregations, and detailed measure data. This endpoint provides a complete view of all measures with their relationships, progress, and summary statistics.
+
+**Endpoint:** `GET /measures/summary`
+
+**Headers:**
+- `Authorization: Bearer {accessToken}`
+- `X-Tenant-Id: {tenantId}`
+
+**Query Parameters:**
+- `category` (optional): Filter by measure category (e.g., "Finance", "Sales", "Customer Success")
+- `ownerId` (optional): Filter by owner (person ID)
+- `status` (optional): Filter by measure status ("active" or "inactive")
+- `progressStatus` (optional): Filter by progress status ("on_track", "at_risk", "behind", "no_data")
+- `period` (optional): Filter by aggregation period ("daily", "weekly", "monthly", "quarterly", "yearly")
+- `includeInactive` (optional): Include inactive measures (default: true)
+- `maxDataPoints` (optional): Maximum trend data points to return (default: 5, 0 = all)

+
+**Progress Status Calculation**
+
+The `progress.status` field is calculated using the following algorithm:
+
+```
+Given:
+- thresholdPct (e.g., 80)
+- riskThresholdPct (e.g., 50)
+- variancePercentage = ((currentValue - expectedValue) / |totalChange|) * 100
+
+Status determination:
+- If variancePercentage >= (thresholdPct - 100) -> on_track
+- If variancePercentage < (thresholdPct - 100) AND variancePercentage >= (riskThresholdPct - 100) -> behind
+- If variancePercentage < (riskThresholdPct - 100) -> at_risk
+- No data -> no_data
+
+Example with thresholdPct = 80, riskThresholdPct = 50:
+- variancePercentage >= -20 -> on_track
+- -50 <= variancePercentage < -20 -> behind
+- variancePercentage < -50 -> at_risk
+```
+
+**Response 400 Bad Request**
+
+```json
+{
+  "success": false,
+  "data": null,
+  "error": "Invalid filter parameters",
+  "timestamp": "2025-01-09T10:30:45Z"

+```
+

+  "data": null,
+  "error": "Unauthorized - Invalid or expired token",
+  "timestamp": "2025-01-09T10:30:45Z"
+}
+```
+
+**Response 500 Internal Server Error**
+
+```json
+{
+  "success": false,
+  "data": null,
+  "error": "Internal server error",
+  "timestamp": "2025-01-09T10:30:45Z"
+}
+```
+
+**Implementation:**
+- Controller: `MeasuresController.GetMeasureSummary()`
+- Handler: `GetMeasureSummaryQueryHandler`
+- Query: `GetMeasureSummaryQuery`
+- Response DTOs: `MeasureSummaryResponse`, `MeasureSummaryItemResponse`, etc.

+### 0a. Get Available Measures For New Goal (No goalId)
+
+Retrieve the Measures catalog (catalog + tenant custom) when designing a goal that is not yet persisted. This mirrors the goal-scoped available-measures payload but does not require a `goalId`; `usageInfo.isUsedByThisGoal` is always `false`.
+
+**Endpoint:** `GET /goals/available-measures`

+- `Authorization: Bearer {accessToken}`
+- `X-Tenant-Id: {tenantId}`
+

+
+**Notes**
+- Same schema as goal-scoped available-measures but without validating goal existence.
+- `usageInfo.isUsedByThisGoal` is always `false` for this endpoint; `goalCount` still reflects usage across persisted goals.
+- Use [Measure Links API](./measure-links-api.md) to link a Measure once the goal is created.
+
+### 1. List Measures
+
+Retrieve Measures with optional filtering.
+
+**Endpoint:** `GET /measures`
+
+#### Query Parameters
+
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `ownerId` | string (GUID) | No | Filter by Measure owner (person responsible) |
+| `goalId` | string (GUID) | No | Filter by linked goal |
+| `strategyId` | string (GUID) | No | Filter by linked strategy |
+
+**Default Behavior:** If no filter is provided, returns all Measures for the tenant (useful for dropdowns and lists).
+
+#### Request Example
+
+```http
+GET /measures?goalId=550e8400-e29b-41d4-a716-446655440000

+
+### 7. Get Available Measures for New Goals
+
+Retrieve the Measure catalog for a tenant when designing a new goal that is not yet persisted. Returns the same payload as `GET /goals/{goalId}/available-measures` but does not require a `goalId`. Usage data reflects existing goal links across the tenant; `usageInfo.isUsedByThisGoal` is always `false` because no goal is supplied.
+
+**Endpoint:** `GET /goals/available-measures`
+
+#### Response 200
+
+```json
+{
+  "success": true,
+  "data": {

+          "goalCount": 1,
+          "isUsedByThisGoal": false
+        }
+      }
+    ]
+  },
+  "error": null,
+  "timestamp": "2026-01-02T00:00:00.000Z"
+}
+```
+
+#### Notes
+
+- Use when the frontend constructs a goal in-memory and needs the catalog before persisting the goal.
+- Usage counts still reflect existing goal links in the tenant; `isUsedByThisGoal` remains `false`.
+- Response shape matches `GET /goals/{goalId}/available-measures` for compatibility.
+

+
+### 8. Get Measure Linked Goals (Deprecated)
+
+⚠️ **DEPRECATED (Issue #374):** This endpoint is being migrated to the new MeasureLink design.
+
+**Endpoint:** `GET /measures/{id}/linked-goals`
+
+#### Current Behavior
+
+Returns `501 Not Implemented` with migration message.
+
+```json
+{
+  "success": false,
+  "data": null,
+  "error": "This endpoint is being migrated to the new MeasureLink design. Please use the new MeasureLink endpoints."
+}
+```
+
+#### Migration Path
+
+Use the following endpoints instead:
+- **List Measure Links:** `GET /measure-links?measureId={id}`
+- **Measure Details with Links:** `GET /measures/{id}` (includes `linkedGoals` in response)
+
+See [Measure Links API](./measure-links-api.md) for details.
+
+---
+
+### 9. Get Measure Options (Issue #469)
+
+Retrieve options for a Qualitative measure. Returns measure-owned options if they exist, otherwise returns inherited options from the linked catalog.

+      "sortOrder": 2
+    },
+    {
+      "numericValue": 3,
+      "label": "Met",
+      "description": "Performance at or above target",
+      "sortOrder": 3
+    }
+  ]
+}
+```
+
+#### Request Fields
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `options` | array | **Yes** | Options to set (minimum 2) |
+| `options[].numericValue` | integer | **Yes** | Unique numeric value for aggregation |
+| `options[].label` | string | **Yes** | Display label (max 100 chars) |
+| `options[].description` | string | No | Explanation text |
+| `options[].sortOrder` | integer | No | Display order (defaults to numericValue) |
+
+#### Response
+
+**Status:** `200 OK`
+
+```json
+{
+  "success": true,
+  "data": {
+    "options": [...],
+    "isInherited": false,
+    "sourceCatalogId": null
+  },
+  "error": null
+}
+```
+
+#### Validation Rules
+
+- Minimum 2 options required
+- `numericValue` must be unique within the measure
+- `label` is required and max 100 characters
+- Replaces all existing measure-owned options
+
+---
+
+### 11. Delete Measure Options (Issue #469)
+
+Delete all measure-owned options. After deletion, the measure will inherit options from its linked catalog (if any).
+
+**Endpoint:** `DELETE /measures/{id}/options`
+
+#### Path Parameters
+
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `id` | string (GUID) | **Yes** | Measure identifier |
+
+#### Response
+
+**Status:** `204 No Content`
+
+(No response body on success)
+
+#### Business Rules
+
+- Only deletes measure-owned options
+- Does not affect catalog options
+- After deletion, measure inherits from catalog (if linked)
+
+---
+
+### 12. Copy Options from Catalog (Issue #469)
+
+Copy options from a catalog entry to create measure-owned options. Use this to "detach" a measure from its catalog's options for customization.
+
+**Endpoint:** `POST /measures/{id}/options/copy-from-catalog/{catalogId}`
+
+#### Path Parameters
+
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `id` | string (GUID) | **Yes** | Measure identifier |
+| `catalogId` | string (GUID) | **Yes** | Catalog identifier to copy from |
+
+#### Response
+
+**Status:** `200 OK`
+
+```json
+{
+  "success": true,
+  "data": {
+    "options": [
+      {
+        "id": "new-opt-001",
+        "measureId": "measure-123",
+        "catalogId": null,
+        "numericValue": 1,
+        "label": "Not Met",
+        "description": "Performance below target",
+        "sortOrder": 1
+      },
+      ...
+    ],
+    "isInherited": false,
+    "sourceCatalogId": null
+  },
+  "error": null
+}
+```
+
+#### Business Rules
+
+- Creates new option records owned by the measure
+- Copied options are independent of catalog (future catalog changes don't affect them)
+- If measure already has options, they are replaced
+
+---
+
+## Data Models
+
+### MeasureDirection Enum
+
+```typescript
+enum MeasureDirection {
+  Increase = "Increase", // Higher is better (e.g., revenue, customers)
+  Decrease = "Decrease"  // Lower is better (e.g., costs, churn)
+}
+```
+
+### MeasureType Enum
+
+> **Note:** MeasureType describes how values are **represented and input** (Quantitative = direct number, Qualitative = select from options). This is different from indicator classification (leading/lagging) which may be tracked separately.
+
+```typescript
+enum MeasureType {
+  Quantitative = "Quantitative",  // Direct numeric input (e.g., $50,000 revenue)
+  Qualitative = "Qualitative",    // Select from labeled options (e.g., "Excellent" = 5)
+  Binary = "Binary"               // DEPRECATED: Use Qualitative with 2 options instead
+}
+```
+
+**Examples:**
+- **Quantitative:** Revenue ($50,000), Temperature (72°F), Customer Count (1,500)
+- **Qualitative:** Satisfaction (Excellent/Good/Fair/Poor → 4/3/2/1), Risk Level (High/Medium/Low → 3/2/1)
+- **Binary (deprecated):** Complete (Yes/No) - migrate to Qualitative with options Yes=1, No=0
+
+
+### Common Categories
+
+Standard Measure categories (not enforced, but commonly used):
+- `Finance` - Revenue, costs, profitability
+- `Sales` - Pipeline, conversions, deals
+- `Marketing` - Leads, CAC, ROAS
+- `Customer Success` - Retention, satisfaction, NPS
+- `Operations` - Efficiency, productivity, quality
+- `Product` - Usage, adoption, feature metrics
+- `HR` - Headcount, turnover, engagement
+
+---
+
+## Error Handling
+
+### Standard Error Response
+
+```json
+{
+  "success": false,
+  "data": null,
+  "error": "Error message here"
+}
+```
+
+### Common Error Codes
+
+| Code | Scenario | Message Example |
+|------|----------|-----------------|
+| 400 | Invalid GUID format | "Invalid Measure ID format" |
+| 400 | Missing required field | "Name is required" |
+| 400 | Invalid enum value | "Direction must be 'Increase' or 'Decrease'" |
+| 401 | Missing/invalid token | "Unauthorized" |
+| 403 | Insufficient permissions | "Access denied to this Measure" |
+| 404 | Measure not found | "Measure not found" |
+| 422 | Validation failure | "Target value must be greater than 0" |
+| 500 | Server error | "Internal server error" |
+
+---
+
+## Frontend Usage Examples
+
+### TypeScript Service
+
+```typescript
+import { traction } from './traction';
+
+// List Measures for a goal
+const measures = await traction.get<PaginatedMeasuresResponse>('/measures', {
+  params: { goalId: 'goal-123' }
+});
+
+// Create catalog-based Measure
+const newMeasure = await traction.post<MeasureResponse>('/measures', {
+  name: 'Customer Acquisition Cost',
+  catalogId: 'measure-catalog-003',
+  targetValue: 100.00,
+  unit: 'USD',
+  ownerId: 'owner-123',
+  strategyId: 'strategy-456'
+});
+
+// Update Measure value
+await traction.put(`/measures/${measureId}/value`, {
+  value: 95.50,
+  recordedAt: new Date().toISOString(),
+  notes: 'Monthly update'
+});
+
+// Get Measure details with linked goals
+const measureDetails = await traction.get<MeasureDetailResponse>(`/measures/${measureId}`);
+console.log(`Linked to ${measureDetails.data.linkedGoals.length} goals`);
+
+// Delete Measure (soft delete)
+await traction.delete(`/measures/${measureId}`);

+## Changelog
+
+### v7.5 (February 6, 2026) - Issue #640: Measure Progress Calculation
+- ✨ **Added:** `progress` field to GET /measures/{id} response
+- 📊 Progress calculation at measure level includes only `progressPercent` (0-100+)
+- 🔧 Progress calculated using primary link (or first link if no primary) thresholds
+- ⚠️ **Note:** Status and variance are NOT included at measure level - those require thresholds which exist at the link level
+- 💡 Calculated from baseline (first actual) to target using domain service for uniform calculation
+- 🔄 Returns `null` if no links exist or insufficient data (requires 2+ actuals and 1+ target)
+
+### v7.4 (January 10, 2026) - Issue #527: Link-Level Progress
+- ✨ **Added:** `progress` field to `goalLinks` and `strategyLinks` in GET /measures/summary response
+- 🔄 **Changed:** Progress moved from measure level to link level for accurate per-goal/strategy tracking
+- 📊 Progress calculation includes: progressPercentage, status (on_track/at_risk/behind/no_data), variance, variancePercentage, daysUntilTarget, isOverdue
+- 🧮 Implemented via domain service pattern (`MeasureLinkProgressService`) following DDD principles
+- 📝 Each link has independent progress based on its own threshold configuration
+
+### v7.3 (January 9, 2026) - Issue #526: Measure Summary Endpoint
+- ✨ Added `GET /measures/summary` - Comprehensive measure tracker with filtering and aggregations
+- 📊 Includes progress calculations, goal/strategy links, trend data, and summary statistics

+- ✨ Added `DELETE /measures/{id}/options` - Delete measure-owned options
+- ✨ Added `POST /measures/{id}/options/copy-from-catalog/{catalogId}` - Copy catalog options
+- 📝 **Fixed MeasureType enum documentation** - Changed from Leading/Lagging to Quantitative/Qualitative/Binary
+- ⚠️ Deprecated `Binary` MeasureType - Use Qualitative with 2 options instead
+- 📝 Clarified Type vs ValueType terminology (Type = input method, ValueType = data nature)
+
+### v7.1 (January 2, 2026)
+- ✨ Added `GET /goals/available-measures` for new (unpersisted) goals
+- 📝 Renamed spec files to `measures-*` for consistency

+### 4. Update Strategy Alignment
+
+**PATCH** `/goals/{goalId}/strategies/{id}/alignment`
+
+Update strategy alignment scores calculated by the Coaching Service AI.
+
+**Purpose:** This endpoint persists alignment data calculated by the Coaching Service, which evaluates how well the strategy aligns with:
+- The goal's intent and objectives
+- The business foundation (vision, purpose, core values)
+- Company strategy and market positioning
+
+#### Path Parameters
+
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `goalId` | string (GUID) | Yes | Goal identifier |
+| `id` | string (GUID) | Yes | Strategy identifier |
+
+#### Request Body
+
+```json
+{
+  "alignmentScore": 92,
+  "alignmentExplanation": "Strategy aligns strongly with company vision to become market leader in cloud solutions. Direct connection to 'Innovation' and 'Customer Focus' core values. Supports goal of increasing market share by 15%.",
+  "alignmentSuggestions": [
+    "Consider adding customer satisfaction metrics to track alignment with 'Customer Focus' value",
+    "Link to brand awareness Measures to measure market leadership progress"
+  ]
+}
+```
+
+#### Request Fields
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `alignmentScore` | number | Yes | 0-100: How well strategy aligns with goal and business foundation |

+| `alignmentSuggestions` | string[] | No | AI-generated suggestions for improving alignment |
+
+#### Response (200 OK)
+
+```json
+{
+  "success": true,

+    ],
+    "updatedAt": "2025-01-21T10:15:00Z"
+  }
+}
+```
+
+#### Business Rules
+
+- **Alignment Score:** Must be between 0-100
+- **Frontend Flow:**
+  1. Frontend calls Coaching Service to calculate alignment

Subject: [PATCH 3/7] fix(cors): restore preprod and production preflight
 handling

Ensure browser preflight requests always return CORS headers by configuring API Gateway for allowed frontend origins and relaxing app-level allowed headers. Add a stronger production smoke test that validates all purposepath.app frontend origins and common tracing headers to prevent regressions.

Subject: [PATCH 7/7] docs: add resolve-production-issue command workflow

Add a dedicated Cursor command for production incident handling that mirrors resolve-issue principles while enforcing the hotfix path: preprod validation, hotfix-to-master promotion, and mandatory downstream merges to staging and dev.

+# Resolve Production Issue - Mandatory Hotfix Workflow
+
+## CRITICAL: Follow #file:../rules/cursorrules.mdc EXACTLY
+
+### STEP 1: Prepare Hotfix Branch (MANDATORY)
+
+#### Branch Setup
+- [ ] Ensure clean working tree (starting from local `dev`)
+- [ ] Fetch latest remote references: `git fetch origin`
+- [ ] Create hotfix branch from remote master: `git checkout -b hotfix/issue-{ISSUE}-{slug} origin/master`
+- [ ] Add `in-progress` label to the issue: `gh issue edit {ISSUE} --add-label in-progress`
+- [ ] Keep implementation scoped only to production fix requirements
+- [ ] Ensure preprod compatibility for config/deployment updates
+
+---
+
+### STEP 2: Issue Intake & Plan Confirmation
+
+- [ ] Read the full issue, incident details, and any linked docs/runbooks
+- [ ] Identify blast radius (service, API routes, infra, data, auth, tenant impact)
+- [ ] Define rollback and validation strategy before coding
+- [ ] Post issue comment with:
+      - root-cause hypothesis
+      - planned fix scope
+      - preprod + production validation plan
+- [ ] STOP! Announce plan and wait for user approval before changes
+
+### STEP 3: Implement Hotfix (Scoped + Safe)
+
+- [ ] Implement only the minimal safe fix for production behavior
+- [ ] Follow Python + FastAPI clean architecture conventions:
+      - Domain entities in `coaching/src/domain/entities/`
+      - Value objects in `coaching/src/domain/value_objects/`
+      - Ports in `coaching/src/domain/ports/`
+      - Application services in `coaching/src/application/`
+      - Infrastructure adapters in `coaching/src/infrastructure/`
+      - API routes in `coaching/src/api/routes/`
+      - Core types/constants in `coaching/src/core/`
+- [ ] Use Pydantic models, not untyped `dict[str, Any]` in domain
+- [ ] Preserve tenant isolation checks on all data access
+- [ ] Update workflow/deployment checks when reliability is part of the incident
+- [ ] Remove temporary code, debug logs, and dead code
+
+### STEP 4: Validate on Hotfix Branch (Preprod First)
+
+- [ ] Run lint/type/tests locally before push:
+      ```powershell
+      # Lint + format
+      python -m ruff check coaching/ shared/ --fix
+      python -m ruff format coaching/ shared/
+
+      # Type checking
+      python -m mypy coaching/src shared/ --explicit-package-bases
+
+      # Tests
+      cd coaching && uv run pytest --cov=src
+      ```
+- [ ] Push hotfix branch: `git push -u origin hotfix/issue-{ISSUE}-{slug}`
+- [ ] Confirm preprod deployment workflow runs successfully
+- [ ] Execute manual validation in preprod for the incident scenario
+- [ ] If validation fails: fix on same hotfix branch and repeat this step
+
+### STEP 5: Promote Hotfix to Production
+
+- [ ] Open PR `hotfix/issue-{ISSUE}-{slug} -> master`
+- [ ] Include incident context, root cause, and validation evidence in PR body
+- [ ] Merge PR only after preprod validation is confirmed
+- [ ] Watch production deployment workflow end-to-end
+- [ ] Verify post-deploy checks:
+      - Lambda/runtime state healthy (if applicable)
+      - API health endpoint responsive
+      - CORS preflight/critical route behavior validated
+
+### STEP 6: Propagate Fix Downstream (MANDATORY)
+
+- [ ] Open PR `master -> staging`, merge after checks pass
+- [ ] Open PR `staging -> dev`, merge after checks pass
+- [ ] Ensure all three branches now contain the hotfix commit(s)
+
+### STEP 7: Close Incident + Cleanup
+
+- [ ] Post closing summary on the issue with:
+      - root cause
+      - final fix
+      - validation evidence (preprod + production)
+      - follow-up actions (if any)
+- [ ] Remove `in-progress` label
+- [ ] Close issue with state_reason: `completed`
+- [ ] Delete hotfix branches (local + remote) only after downstream merges:
+      ```powershell
+      git branch -d hotfix/issue-{ISSUE}-{slug}
+      git push origin --delete hotfix/issue-{ISSUE}-{slug}
+      ```
+
+---
+
+**Non-negotiables:**
+- ❌ Never commit directly to `dev`/`staging`/`master`
+- ❌ Never skip preprod validation before `hotfix -> master` merge
+- ❌ Never leave workflow reliability gaps unverified for deployment incidents
+- ❌ Never leave mock data, TODOs, or `dict[str, Any]` in domain
+- ❌ Never skip tenant isolation checks
+- ✅ Always keep scope to production incident requirements
+- ✅ Always document root cause and validation evidence
+- ✅ Always merge `master -> staging -> dev` after hotfix production release
+- ✅ Always keep docs/config/workflows in sync with the fix
