+
+**E2E test crate with full ingest-to-query pipeline test and grip provenance expansion test using shared TestHarness**
+
+## Performance
+
+- **Duration:** 14 min
+- **Started:** 2026-02-11T03:58:13Z
+- **Completed:** 2026-02-11T04:12:22Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- Created e2e-tests crate with shared TestHarness and reusable helper functions
+- Full pipeline test proves ingest -> TOC segment build -> grip extraction -> BM25 indexing -> route_query returns results
+- Grip provenance test verifies grip expansion returns excerpt events with surrounding context
+- Both tests pass with zero clippy warnings
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create e2e-tests crate with shared TestHarness** - `f5e2358` (feat)
+2. **Task 2: Implement full pipeline E2E test and grip provenance E2E test** - `c479042` (feat)
+
+## Files Created/Modified
+- `Cargo.toml` - Added e2e-tests to workspace members
+- `crates/e2e-tests/Cargo.toml` - E2E test crate definition with workspace dependencies
+- `crates/e2e-tests/src/lib.rs` - Shared TestHarness and helper functions (ingest_events, create_test_events, build_toc_segment)
+- `crates/e2e-tests/tests/pipeline_test.rs` - Two E2E tests: full pipeline and grip provenance
+
+## Decisions Made
+- Used tempfile and rand as regular (not dev-only) dependencies since lib.rs is shared test infrastructure consumed by test binaries
+- Tested RetrievalHandler directly via `tonic::Request` rather than spinning up a full gRPC server — faster, simpler, and sufficient for E2E validation
+- MockSummarizer grip extraction depends on term overlap; test handles zero-grip case gracefully
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Moved tempfile/rand from dev-dependencies to dependencies**
+- **Found during:** Task 1
+- **Issue:** lib.rs uses tempfile::TempDir and rand::random() but these were in dev-dependencies, making them unavailable for the library target
+- **Fix:** Moved tempfile and rand to regular dependencies in Cargo.toml
+- **Files modified:** crates/e2e-tests/Cargo.toml
+- **Verification:** cargo build -p e2e-tests succeeds
+- **Committed in:** f5e2358
+
+**2. [Rule 3 - Blocking] Added tonic as dev-dependency for test Request type**
+- **Found during:** Task 2
+- **Issue:** pipeline_test.rs uses tonic::Request but tonic was not in dev-dependencies
+- **Fix:** Added tonic = { workspace = true } to dev-dependencies
+- **Files modified:** crates/e2e-tests/Cargo.toml
+- **Verification:** cargo test -p e2e-tests passes
+- **Committed in:** c479042
+
+---
+
+**Total deviations:** 2 auto-fixed (2 blocking)
+**Impact on plan:** Both auto-fixes were necessary for compilation. No scope creep.
+
+## Issues Encountered
+- C++ compilation requires `source ./env.sh` to set SDK paths — consistent with all other workspace crates
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- e2e-tests crate and TestHarness are ready for plans 25-02 and 25-03
+- Helper functions (create_test_events, ingest_events, build_toc_segment) are pub for reuse
+- BM25 index path and vector index path are provided by TestHarness

+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-02-11T04:15:05Z
+- **Completed:** 2026-02-11T04:17:57Z
+- **Tasks:** 1

+
+## Accomplishments
+- test_bm25_ingest_index_search_ranked: proves 3 distinct topic segments are ranked correctly by BM25 relevance (Rust query returns Rust segment first, Python query returns Python segment first, gibberish returns 0 results)
+- test_bm25_search_filters_by_doc_type: proves DocType::TocNode and DocType::Grip filters isolate correct document types in search results
+- test_bm25_search_with_agent_attribution: proves contributing_agents propagates through BM25 indexing -- agent-attributed nodes return Some("claude"), non-attributed nodes return None
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Implement BM25 teleport E2E test with relevance ranking (E2E-02)** - `6b3d58d` (feat)
+
+## Files Created/Modified
+- `crates/e2e-tests/tests/bm25_teleport_test.rs` - Three BM25 E2E tests covering relevance ranking, doc type filtering, and agent attribution
+
+## Decisions Made
+- Ranking assertions check segment membership (node_id OR grip_id from that segment) rather than exact node_id. Grips contain the raw excerpt text which may score higher than the TocNode's combined title+bullets for specific queries. A grip from the correct segment ranking first still proves the pipeline works correctly.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed ranking assertion to use segment membership instead of exact node_id**
+- **Found during:** Task 1
+- **Issue:** Plan specified checking results[0].doc_id == node_id, but grips from the same segment may rank higher than the parent TocNode for specific keyword queries
+- **Fix:** Track per-segment doc_id sets (node + all grip IDs) and assert top result is in the correct segment set
+- **Files modified:** crates/e2e-tests/tests/bm25_teleport_test.rs
+- **Verification:** All 3 tests pass
+- **Committed in:** 6b3d58d
+
+---
+
+**Total deviations:** 1 auto-fixed (1 bug)
+**Impact on plan:** Assertion fix necessary for test correctness with BM25's actual ranking behavior. No scope creep.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
