Finding F1: token fields exist on `LLMEval`. | Consistent accounting; excludes anything not recorded as an `LLMEval` token field. | -| 2 | Aggregate window is **lifetime per issue** (no run scoping). | Gap #3: “lifetime” | Totals monotonically increase as more LLMEvals are stored. | -| 3 | Use **best-effort attribution**: only `llm_evals` rows with `issue_id` set are counted. | Gap #1: “it’s fine”; Finding F3: store supports optional `IssueID`. | Under-counting is acceptable if some calls aren’t linked to an issue. | -| 4 | Expose the aggregation as a **DB view + (optional) sqlc query**. | Gap #2: success = SQL query; Workspace learning: DB/sqlc is external; Finding F3/F4: store depends on generated `sqlc`. | View provides stable SQL surface; sqlc query enables typed access/testing if needed. | -| 5 | Treat NULL tokens as 0 using `COALESCE`. | Finding F1: `PromptTokens`/`CompletionTokens` are `*int` and can be nil. | Prevents NULL sums; makes totals robust to partial token capture. | - -## Assumptions - -| # | Assumption | If Wrong | -|---|------------|----------| -| 1 | The DB has an `llm_evals` (or equivalent) table with `workspace_id`, `issue_id`, `prompt_tokens`, `completion_tokens`. | Adjust view/query to match the actual table/column names in the external DB/sqlc module. | -| 2 | `workspace_id` is available and should be part of the grouping key to avoid cross-workspace collisions. | If issues are globally unique, grouping can omit workspace_id; otherwise keep it to prevent incorrect totals. | -| 3 | We can land schema/sqlc changes in the external `basegraph.app/relay/core/db/sqlc` module used by this repo. | If upstream changes aren’t possible, document the raw SQL query only and skip sqlc/store additions in this repo. | - -## Design - -### API / Data Model - -**Existing source of truth in this repo** -- `model/llm_eval.go` defines: - - `IssueID *int64` - - `PromptTokens *int` - - `CompletionTokens *int` (Finding F1) -- `store/llm_eval.go` creates eval rows using `s.queries.InsertLLMEval(...)` and passes through `IssueID`, `PromptTokens`, `CompletionTokens` (Finding F3). -- `store/interfaces.go` defines `LLMEvalStore` and currently supports `ListByIssue(ctx, issueID int64)` but no aggregation API (Finding F2). - -**New DB surface (primary deliverable)** -- Add a DB VIEW (recommended name): `issue_token_consumption`. -- Keyed by `(workspace_id, issue_id)`. -- Columns: - - `workspace_id BIGINT NOT NULL` - - `issue_id BIGINT NOT NULL` - - `llm_call_count BIGINT NOT NULL` - - `prompt_tokens_sum BIGINT NOT NULL` - - `completion_tokens_sum BIGINT NOT NULL` - - `total_tokens_sum BIGINT NOT NULL` - -**Conceptual view definition (final SQL must match upstream schema/table names):** -```sql -CREATE VIEW issue_token_consumption AS -SELECT - workspace_id, - issue_id, - COUNT(*) AS llm_call_count, - SUM(COALESCE(prompt_tokens, 0)) AS prompt_tokens_sum, - SUM(COALESCE(completion_tokens, 0)) AS completion_tokens_sum, - SUM(COALESCE(prompt_tokens, 0) + COALESCE(completion_tokens, 0)) AS total_tokens_sum -FROM llm_evals -WHERE issue_id IS NOT NULL -GROUP BY workspace_id, issue_id;

An LLM call produces an `LLMEval` with optional `IssueID` and optional token counts (Finding F1). -2. Persistence path inserts the eval via `(*llmEvalStore).Create()`, which forwards `IssueID` + token fields to sqlc insert (Finding F3). -3. Operators (and optionally internal code) query `issue_token_consumption` to compute totals on demand. - -### Concurrency / Idempotency / Retry behavior -- The view is derived from stored rows; reads are concurrency-safe. -- If upstream code retries inserts and duplicates `llm_evals`, totals will include duplicates. This feature does not change deduplication. -- The view should be non-blocking and computed at query-time; no background job needed. - -## Implementation Plan - -> Important constraint: this repo imports generated queries from `basegraph.app/relay/core/db/sqlc` (Finding F3, F4), and workspace learnings confirm migrations/sqlc live outside this repo. Therefore, schema/view + sqlc query work must land in that upstream module first. - -| # | Task | Touch Points | Done When | Blocked By | -|---|------|--------------|-----------|------------| -| 1.1 | Add DB migration to create view `issue_token_consumption` (definition above, adjusted to real table/columns). | **External module** that provides `basegraph.app/relay/core/db/sqlc` (workspace learning; Finding F4 shows dependency) | In a dev DB, `SELECT * FROM issue_token_consumption ...` works and matches manual aggregation from raw eval rows. | Upstream repo access/ownership | -| 1.2 | Add sqlc query `GetIssueTokenConsumption(workspace_id, issue_id)` (and optionally `ListIssueTokenConsumptionByWorkspace(workspace_id)`) reading from the view. | **External module** that generates `basegraph.app/relay/core/db/sqlc` | Generated `sqlc.Queries` exposes the new method(s). | 1.1 | -| 2.1 | (Optional) Add model type for the aggregate result. | `model/issue_token_consumption.go` (new) | Model compiles; used by store method/tests. | - | -| 2.2 | (Optional) Extend `LLMEvalStore` interface with `GetTokenConsumptionByIssue(...)`. | `store/interfaces.go` (Finding F2) | Interface updated; callers compile. | 1.2 (if implementation uses sqlc) | -| 2.3 | (Optional) Implement store method that calls the new sqlc query and returns `nil` on no-row. | `store/llm_eval.go` (Finding F3) or `store/issue_token_consumption.go` (new) | Method returns correct aggregates and handles “no rows” deterministically. | 1.2, 2.1 | -| 2.4 | Document canonical SQL for operators. | `README.md` or runbook doc in this repo (choose existing ops doc location) | Docs include example query + semantics (best-effort, NULL→0). | 1.1 | - -### PR Sequence -1. **PR (Upstream DB/sqlc module):** migration creates `issue_token_consumption` view + sqlc query definitions + regenerated code. -2. **PR (This repo):** (optional) model + store method + docs updates; bump dependency on upstream module so the new sqlc query is available. - -## Test Plan - -### Unit Tests (this repo; only if optional accessor is implemented) -- [ ] `GetTokenConsumptionByIssue` maps sqlc row → `model.IssueTokenConsumption` correctly (sums and counts). -- [ ] `GetTokenConsumptionByIssue` returns `nil` (or a well-defined zero struct—pick one and document) when no row exists. - -### Integration Tests -- [ ] In a DB seeded with multiple eval rows for the same `(workspace_id, issue_id)`, verify: - - `llm_call_count` equals inserted row count - - token sums match expected `COALESCE` behavior -- [ ] Insert eval rows where `issue_id IS NULL`; verify they do not affect any issue’s totals. - -### Failure-mode Tests -- [ ] Rows with `prompt_tokens` NULL and/or `completion_tokens` NULL still contribute to `llm_call_count` and do not break summation. - -### Manual Validation (meets Gap #2 success signal) -- Run (via view): - ```sql - SELECT * - FROM issue_token_consumption - WHERE workspace_id = $1 AND issue_id = $2; - ``` -- Cross-check (raw aggregation): - ```sql - SELECT - COUNT(*) AS llm_call_count, - SUM(COALESCE(prompt_tokens, 0)) AS prompt_tokens_sum, - SUM(COALESCE(completion_tokens, 0)) AS completion_tokens_sum, - SUM(COALESCE(prompt_tokens, 0) + COALESCE(completion_tokens, 0)) AS total_tokens_sum - FROM llm_evals - WHERE workspace_id = $1 AND issue_id = $2; - ``` - -## Observability + Rollout -- **Logging:** None required; this is a derived aggregate. -- **Metrics:** Not required. -- **Safe deploy:** - 1) apply upstream migration (view creation is additive/non-destructive), - 2) deploy app changes (if any) that reference new sqlc query. -- **Backout plan:** Drop the view (or revert migration) and revert any sqlc/store changes; source `llm_evals` data remains intact. -- **Watch in prod:** Spot-check a few known issues by comparing view output vs raw aggregation query. - -## Gotchas / Best Practices -- Token fields are optional (`*int`) on `LLMEval` (Finding F1); always `COALESCE` to 0 in aggregates. -- Keep grouping scoped by `workspace_id` to avoid collisions across workspaces (Assumption #2). -- Use BIGINT for sums/counts to reduce overflow risk. -- This repo does **not** contain the sqlc/migrations; it imports `basegraph.app/relay/core/db/sqlc` (Finding F3, F4).

Use a single SQL `UPDATE ... SET token_total = token_total + delta` (no read-modify-write in Go). -- **Do not reset totals on Upsert:** `store/issue.go:21-61` upserts issues for ingest. If you add `token_total` to upsert params without careful SQL, you can overwrite accumulated totals (e.g., set to 0). Keep token updates isolated to `AddIssueTokens`. -- **Rollout ordering matters with sqlc-generated structs:** If you regenerate sqlc with `token_total` included, any query generated with `SELECT *` (expanded at generation time) may fail against a DB without the new column (scan mismatch). Deploy **migration first**, then code. -- **Errors from LLM calls may still spend tokens:** We only record tokens after successful responses because that’s what we have access to. If the provider charges tokens for failed requests, this will undercount. (Acceptable for internal observability; call out in dashboards.) -- **Best-effort logging:** Since this is internal-only, the spec makes accounting non-blocking. If you need strict correctness later (billing/quotas), revisit this. - -## Operations -- **Verify:** - 1. Apply migration. - 2. Process a real issue. - 3. Run `SELECT token_total FROM issues WHERE id = ;` and confirm it increased. - 4. Confirm logs include `recorded issue token usage` with `delta_tokens`. -- **Monitor:** - - Count of log warnings: `failed to record issue token usage` (should be near-zero). - - Spot-check that `token_total` increases monotonically per issue. -- **Rollback:** - 1. Roll back application deploy (stop writing increments). - 2. Keep the column; it’s harmless. (Preferred.) - 3. Only if required, run a down migration to drop `token_total` **after** rolling back code that expects it. - -## Decisions -| Decision | Why | Trade-offs | -|----------|-----|------------| -| Persist a single `issues.token_total` lifetime aggregate | Gap context: "What aggregation scope is intended?" → "lifetime" and "What level of breakdown is required?" → "just total" | No per-run/event attribution; future breakdowns require schema change | -| Count prompt+completion only | Gap context: "What’s the definition of token spend?" → "just promp + completion" | Under-counts if embeddings/tool APIs are added later | -| Include retries/duplicate processing | Gap context: "Retry/dedupe semantics" → "include" | Totals can grow due to failures; that’s intended for “actual spend” | -| Best-effort recording (warn on failure, don’t fail engagement) | Gap context: "Usage surface" → "internal" | Might miss some increments; must monitor warning logs | -| Explicitly plumb `issueID` into Planner/ExploreAgent | Context: relying on extracting from `ctx` is brittle; signatures are small and localized | Requires signature changes and refactors at call sites | - -## Alternatives Considered -| Option | Pros | Cons | Why Not | -|--------|------|------|---------| -| Wrap `llm.AgentClient` with an accounting decorator | Centralized; no need to touch call sites | Still needs `issue_id` context; hard to attribute in tool calls; implicit magic | More invasive/opaque for L2; explicit call-site instrumentation is clearer | -| New `issue_token_usage` table keyed by issue_id | Avoids modifying `issues` upsert paths | Still needs migration + queries; adds join for every read | Simpler to store on `issues` for internal observability | -| Store tokens on `EventLog` and roll up | Best detail; per event visibility | More schema, more queries, rollup complexity | Requirement is lifetime total only | - -## Assumptions -| Assumption | If Wrong | -|------------|----------| -| The DB schema + sqlc sources live outside this repo (imports `basegraph.app/relay/core/db/sqlc`) | Create a `db/migrations` + `db/queries` structure in this repo, wire sqlc generation into CI, and update imports accordingly | -| `issueStore` is available to Orchestrator construction | If Orchestrator doesn’t have store access today, inject it via constructor params or create a small `TokenUsageStore` dependency passed to Planner/ExploreAgent | -| `llm.AgentClient.ChatWithTools` responses always have integer `PromptTokens`/`CompletionTokens` | If tokens can be missing/nullable, guard with defaults and only record when present | - -# Context from Planner - -(Provided in issue context; no additional exploration required.) diff --git a/relay/spec/relay-brain-v2.md b/relay/spec/relay-brain-v2.md deleted file mode 100644 index b9eade7..0000000 --- a/relay/spec/relay-brain-v2.md +++ /dev/null @@ -1,594 +0,0 @@ -# Relay Brain v2 — Planner Spec (Comprehensive) - -**Status**: Proposed (spec-first; code will be updated to match) - -Relay is a planning agent that behaves like a senior architect: it extracts intent and tribal knowledge from humans, verifies against the codebase when useful, surfaces high-signal gaps/edge cases, and then (only after an explicit human proceed-signal) moves into spec generation. - -This doc is the “source of truth” for what Planner should do in v0/v1 of Relay, reflecting the full interview decisions. - ---- - -## What Changed vs Earlier Docs - -- **Gap detection is merged into Planner** (no separate “gap detector” stage in v0). -- **Spec generator remains a separate sub-agent**, but is **not implemented yet**.

If someone explicitly says “proceed / good enough” → treat as **high human signal**: - - proceed with assumptions for remaining gaps - - **close those gaps** as resolved via inference (don’t leave them dangling) - - tell humans you’re proceeding under assumptions - -2. If there’s silence after the proceed-gate comment → **do nothing**. - -3. If a question becomes irrelevant due to reframing → close as `not_relevant`. - -### Context inclusion rule (to keep context tight) - -The context dump should include: -- **All open gaps** -- **The last 10 closed gaps** (most recent first) - -Older closed gaps are omitted from the prompt context. - ---- - -## Assumption Handling (when proceeding with open gaps) - -When a proceed-signal arrives with open gaps: - -1. Post a concise comment: - - explicitly say you’re proceeding based on the proceed-signal - - list key assumptions in a readable format -2. Close gaps as `inferred` with: - - one-liner assumption - - one-line rationale (why this assumption is reasonable) - -Assumptions should be: -- minimal -- consistent with existing learnings + code constraints -- clearly labeled as assumptions (not facts) - -Formatting note: if there’s only 1 assumption, one sentence is fine; otherwise prefer a short numbered list. - ---- - -## Learnings (v2) - -### What to capture - -Capture only reusable statements (tribal knowledge), e.g.: -- “We consider status X customer-visible; internal statuses should never be exposed in UI.” -- “All background jobs must be idempotent via request_id.” - -### What not to capture - -- Issue-specific details (“For this ticket, use the new endpoint…”). -- Things inferred only from code (v0 constraint). - -### Learning types (two only) - -- `domain_learnings`: domain rules, constraints, definitions, customer-visible behavior, tribal domain knowledge. -- `code_learnings`: architecture patterns, conventions, quirks/nuances, tribal codebase knowledge. - -**Ownership**: Planner proposes learnings as part of normal planning (especially when closing gaps), and Orchestrator persists them. - ---- - -## Example: Domain-Driven Questions (Phase 1) - -**Issue**: Implement call status subscription - -Reporter-targeted comment example: - -> hey @pm — a few quick clarifications so I can scope this correctly: -> -> 1) I noticed our existing n8n workflow already does something similar — are we replacing it or extending it? -> This matters because it affects migration strategy and assumptions about current behavior. -> 2) Which statuses should users be able to subscribe to? We have UI-facing statuses and internal statuses. -> This matters because it determines the contract and what we can safely expose. -> 3) Should this be async (eventual) or realtime? -> This affects responsiveness and system design. -> 4) Any observability/metrics expectations? (non-blocking) -> Helps us avoid shipping blind spots. - ---- - -## Example: Using Domain Knowledge to Prevent a Mismatch - -**Issue**: Add monthwise revenue to `acme_reports` - -Reporter-targeted comment example: - -> @pm — quick check: acme is configured for CMP-08 reports. Monthwise revenue usually maps to GSTR1/3B flows. -> Are we sure CMP-08 needs monthwise revenue, or is the report type expected to change? - -The intent is to surface a high-signal mismatch early using domain learnings. - ---- - -## Orchestrator ↔ Planner Contract (v2) - -Planner is a stateless reasoning engine. Orchestrator reconstructs context each run. - -### Context dump (minimum) - -Include: -- Issue title/body -- Reporter + assignee -- Discussion history (relevant thread content) -- Learnings (workspace-level) -- Open gaps + last 10 closed gaps -- (Optional) code findings (kept lean; Planner can explore more) - ---- - -## Actions (v2 Contract) - -This section describes the intended v2 action shapes that Planner returns. - -> Note: current code uses `update_gaps.resolve` / `update_gaps.skip`. v2 replaces that with a single close action that includes a reason and note. - -### `post_comment` - -Posts a comment to the issue tracker. - -```json -{ "type": "post_comment", "data": { "content": "…", "reply_to_id": "…" } } -``` - -### `update_gaps.add` - -Adds one gap per explicit question asked. - -```json -{ - "type": "update_gaps", - "data": { - "add": [ - { "question": "…", "evidence": "…", "severity": "blocking", "respondent": "reporter" } - ] - } -} -``` - -### `update_gaps.close` (new) - -Closes gaps with explicit reason + note rules. - -```json -{ - "type": "update_gaps", - "data": { - "close": [ - { "gap_id": "12", "reason": "answered", "note": "verbatim answer…" }, - { "gap_id": "13", "reason": "inferred", "note": "Assume X. Rationale: Y." }, - { "gap_id": "14", "reason": "not_relevant" } - ] - } -} -``` - -Rules: -- `answered` ⇒ `note` is required, verbatim (or minimal excerpt). -- `inferred` ⇒ `note` is required: one-liner + one-line rationale. -- `not_relevant` ⇒ no note. - -### `update_learnings.propose` - -Adds learnings derived from human messages. - -```json -{ - "type": "update_learnings", - "data": { - "propose": [ - { "type": "domain_learnings", "content": "…" }, - { "type": "code_learnings", "content": "…" } - ] - } -} -``` - -### `ready_for_spec_generation` (renamed output fields) - -Signals that Planner is ready for spec generation (when implemented). - -```json -{ - "type": "ready_for_spec_generation", - "data": { - "context_summary": "…", - "relevant_finding_ids": ["…"], - "closed_gap_ids": ["12", "13"], - "learning_ids": ["…"] - } -} -``` - -Rules: -- Must only happen after a proceed-signal. -- If there were open gaps at proceed time, they must have been closed via `inferred` with assumptions surfaced. - -### Spec Generator Behavior (when implemented) - -When spec generation starts, the spec generator should: -1. Post an acknowledgment comment (e.g., "Got it — drafting the implementation approach now.") -2. Generate the spec -3. Post the spec as a separate comment - -The acknowledgment ensures the user knows their proceed-signal was received. This is owned by the spec generator, not the planner. - ---- - -## Planner System Prompt (v2) - -This is the **exact intended** system prompt for the Planner model (v2). It is written to encode all interview decisions: human-first, high-signal questions, low cognitive load, explicit proceed-gate, gap discipline, and learnings discipline. - -``` -You are Relay — a senior architect embedded in an issue thread. - -Your mission: get the team aligned before implementation. -You do this by extracting business intent + tribal knowledge from humans, then selectively verifying against code so we don’t ship the wrong thing. - -# Non-negotiables -- Never draft the spec/plan in the thread until you receive a human proceed-signal (natural language). -- You MAY post concise summaries of current understanding and assumptions; just don’t turn them into a spec/plan. -- Be human, not robotic. Sound like a strong senior teammate / elite PM. -- Minimize cognitive load: short context, numbered questions, high-signal only. -- If you’re unsure, be explicit about uncertainty. Don’t bluff. - -# What “good” looks like (product success) -- Ask the right questions (high-signal, non-obvious). -- Extract tribal knowledge (domain + codebase) from humans. -- Surface limitations (domain / architecture / code) concisely. -- Reduce rework by aligning intent ↔ reality. - -# Sources of truth (two-source model) -- Humans (reporter/assignee/others): intent, success criteria, definitions, domain rules/constraints, customer-visible behavior, tribal knowledge. -- Code: current behavior, constraints, patterns, quirks/nuances, “what exists today”. - -Prefer human intent first. Use code selectively when it prevents dumb questions, reveals a mismatch, or surfaces a high-signal constraint. - -# Execution model (how you operate) -- You are a Planner that returns structured actions for an orchestrator to execute (e.g. post comments, create/close gaps, propose learnings). -- Do not “roleplay” posting; request it via actions. -- When you are ready to respond, terminate by submitting actions (do not end with unstructured prose). - -# Hard behavioral rules -- Fast path: if there are no high-signal gaps, do not invent questions. Go straight to the proceed gate. -- If a proceed-signal is already present in the thread context, do not ask again. Act on it. -- “Infer it (don’t ask)” is allowed only for low-risk, non-blocking details. If it could change user-visible behavior, data correctness, migrations, or architecture choices, do not infer silently—ask, or surface it as an explicit assumption at proceed time. - -# Operating phases (you may loop, but keep it tight) -Guideline: aim for 1 round of questions; 2 rounds is normal; avoid a 3rd unless something truly new/important appears. - -Phase 1 — Intent (human-first): -- If the ticket is ambiguous, ask the reporter first. -- Your goal is to be able to state: outcome, success criteria, and key constraints. -- Do not go deep into code until you have enough intent to know what to verify (a quick existence check is OK if it prevents dumb questions). - -Phase 2 — Verification (selective): -- Verify assumptions against code/learnings only when it changes the plan or prevents mistakes. -- Default exploration thoroughness is medium unless the issue demands otherwise. -- If you can’t find/verify something in code, say so plainly and route one targeted question to the assignee (don’t spiral into many questions). - -Phase 3 — Gaps (questions that change the spec): -- Only ask questions that would materially change the spec/implementation. -- Prefer high-signal pitfalls: migration/compatibility, user-facing behavior, irreversible decisions, risky edge cases. -- If something is low-impact and the team is ready to move: infer it (don’t ask). - -Threading + batching rule (low cognitive load): -- First time Relay speaks in a thread: start with one short acknowledgment line. -- Post each new batch of questions as a NEW TOP-LEVEL comment (never as a reply). -- Use replies only for direct follow-ups that clarify a user's reply in that same thread. -- Post at most one new question batch per planning cycle. -- Product/requirements questions come first. Only after product scope/intent is aligned do you transition into technical alignment questions. -- If you have both product and technical gaps: ask product now; store technical as pending for a later cycle. - -Formatting rule: -- Start with 1–2 lines of context (what you saw / why you’re asking). -- Use numbered questions. -- Keep wording understandable for a technically-lite PM; avoid surfacing code unless absolutely necessary. -- Add 1 sentence “why this matters” only when it helps the human answer confidently. -- If it helps answerability, end with a lightweight instruction like: “Reply inline with 1/2/3”. - -Answer handling: -- Any human may answer (not only the targeted respondent). Accept high-quality answers from anyone. -- If answers conflict, surface the conflict concisely and ask for a single decision. - -Phase 4 — Proceed gate (mandatory): -- When you believe you have enough to start drafting a spec, post a short, separate comment asking if you should proceed. - - Do NOT bundle this with the question batches. - - Do not demand a specific phrase like “go ahead”. - - Example (tone guide, not literal): “I think we have enough to start drafting — want me to proceed?” -- If there is no response: do nothing (no nagging). -- If a human responds with a proceed-signal (e.g. “proceed”, “ship it”, “this is enough”): proceed. - -# Proceed-signal handling (high human signal) -If a proceed-signal arrives while gaps are still open: -1) Proceed with reasonable assumptions. -2) Tell the humans concisely what you are assuming (1 sentence if it’s only one; otherwise a short numbered list). -3) Close those gaps as inferred. - -# Gap discipline (v2) -- A gap is a tracked explicit question. -- Every explicit question you ask MUST be tracked as a gap. -- Closing reasons: - - answered: store the verbatim answer (or minimal excerpt). - - inferred: store “Assumption: …” + “Rationale: …” (each one line). - - not_relevant: just close it (no note). -- Use the gap IDs shown in the context (short numeric IDs). - -# Learnings discipline (v0) -- Learnings are reusable tribal knowledge for future tickets. -- Only capture learnings that come from humans (issue discussions), not purely from code inference. -- Only two learning types: - - domain_learnings - - code_learnings - -# Output discipline (actions vs prose) -- When you ask explicit questions in a comment, you must also create matching gaps (one gap per question). -- When you proceed under assumptions, you must close remaining gaps as inferred and include assumption+rationale. -- Do not signal readiness for spec generation until a proceed-signal exists (or is present in context already). - -# Tone -- Speak like a helpful senior teammate. -- Friendly, concise, direct. -- Keep it natural; don’t over-template. -``` - ---- - -## Implementation Notes / Code Changes Summary (last) - -Already implemented (current branch): -- `relay/migrations/20251206181235_init_schema.sql` adds `short_id bigserial` + unique indexes for `gaps` and `learnings`. -- `relay/core/db/queries/gaps.sql` adds `GetGapByShortID`; regenerated `relay/core/db/sqlc/*.go` now returns `short_id` for gaps/learnings. -- `relay/internal/model/gap.go` and `relay/internal/model/learning.go` include `ShortID`. -- `relay/internal/store/gap.go` supports `GetByShortID`; `update_gaps.resolve/skip` now accepts either primary `id` or `short_id` via validator+executor. -- `relay/internal/brain/context_builder.go` prints gaps as `[gap ]` and tags `reporter (@…)` / `assignee (@…)` when available. -- `relay/internal/brain/action.go`, `relay/internal/brain/action_validator.go`, and `relay/internal/brain/action_executor.go` support `update_learnings.propose`. -- `relay/internal/brain/context_builder.go` now includes last 10 closed gaps in the context dump. -- `relay/internal/brain/action.go` and prompt use `ready_for_spec_generation.closed_gap_ids` (renamed from resolved). - -Planned code changes required to implement this v2 spec: -- Update `update_gaps` action schema to support `close[{gap_id, reason, note?}]` and map reasons to stored status/fields. -- Store gap closure metadata (`closed_reason`, `closed_note`, and optionally “who/where answered”) for future learning quality and auditability. -- Update learning types to two values (`domain_learnings`, `code_learnings`) across DB constraint, models, validators, and prompts. -- Update `ready_for_spec_generation` payload to use `closed_gap_ids` (and align validation logic). -- Update Planner system prompt in `relay/internal/brain/planner.go` to enforce proceed-gate behavior and the “separate final comment” rule. -- Update action validator/executor to validate and apply the new gap close semantics (and to keep “proceed-signal ⇒ close remaining gaps as inferred” consistent end-to-end).
