+# Context Manager Task 3 Implementer Report
+
+## Status
+- Done
+- Implemented heuristic transcript-slice extraction in `.pi/agent/extensions/context-manager/src/extract.ts`
+- Added focused tests in `.pi/agent/extensions/context-manager/src/extract.test.ts`
+
+## Changes
+- Added `TranscriptSlice` and `extractCandidates()`.
+- Reused `MemoryCandidate`, `MemoryScope`, and `MemorySourceType` from `src/ledger.ts`.
+- Added heuristics for:
+  - user goal extraction
+  - role-aware constraint extraction
+  - decision extraction
+  - next-step / task extraction
+  - file reference extraction
+- Kept constraint extraction from duplicating structured `Goal:`, `Decision:`, and `Next:` lines so the output matches the requested candidate set.
+
+## Tests
+- Verified red state first:
+  - `cd .pi/agent/extensions/context-manager && npx tsx --test src/extract.test.ts`
+  - Result: failed with `ERR_MODULE_NOT_FOUND` because `src/extract.ts` did not exist
+- Verified green state after implementation:
+  - `cd .pi/agent/extensions/context-manager && npx tsx --test src/extract.test.ts`
+- Ran full extension test suite:
+  - `cd .pi/agent/extensions/context-manager && npm test`
+
+## Files Changed
+- Created `.pi/agent/extensions/context-manager/src/extract.ts`
+- Created `.pi/agent/extensions/context-manager/src/extract.test.ts`
+- Created `.pi/reviews/context-manager-task3-implementer-report.md`
+
+## Self-Review Findings
+- The implementation is tightly scoped to extraction only.
+- Test coverage matches the task requirements and verifies both user and non-user sources.
+- File reference extraction is intentionally heuristic and limited to the requested extensions.
+
+## Concerns
+- The provided implementation snippet would also classify `Decision: ... avoid ...` as a constraint; I prevented that duplicate extraction so the required tests pass.
+- No other concerns.
