# Context Manager Task 6 Fix Report
## Status
- Completed
- Task 6 review findings addressed in the context-manager extension
- Verification commands requested in the task were run and passed
## Changes
- Added authoritative branch rebuild logic in `.pi/agent/extensions/context-manager/index.ts`.
- Syncs the runtime context window
- Reads the latest valid snapshot from `ctx.sessionManager.getBranch()`
- Restores snapshot metadata with an empty ledger
- Replays `user`, `assistant`, and `toolResult` messages from the active branch into the runtime
- Refreshes the footer status from the rebuilt runtime
- Hooked that rebuild logic into:
- `session_start`
- `turn_end` (before snapshot persistence)
- `session_tree`
- Kept incremental `tool_result` ingestion for in-turn responsiveness, but the branch rebuild is now authoritative at synchronization points.
- Tightened some extension-boundary typing in `index.ts` while making the fix.
- Replaced the shallow registration-only test with integration-style coverage that exercises the registered handlers.
## Tests
- `cd /home/alex/dotfiles/.worktrees/context-manager-extension/.pi/agent/extensions/context-manager && npx tsx --test src/extension.test.ts`
- Passed: 3/3
- `cd /home/alex/dotfiles/.worktrees/context-manager-extension/.pi/agent/extensions/context-manager && npm test`
- Passed: 38/38
- `cd /home/alex/dotfiles/.worktrees/context-manager-extension && git diff --check -- .pi/agent/extensions/context-manager/index.ts .pi/agent/extensions/context-manager/src/extension.test.ts`
- Passed with no diff/whitespace errors
## Files Changed
- `.pi/agent/extensions/context-manager/index.ts`
- `.pi/agent/extensions/context-manager/src/extension.test.ts`
- `.pi/reviews/context-manager-task6-fix-report.md`
## Self-review Findings
- `turn_end` now persists snapshots built from the actual current branch, so the ledger includes facts extracted from branch `user` and `assistant` messages instead of depending on `tool_result` events alone.
- `session_tree` now resets runtime state immediately after navigation, so the next `context` packet reflects the destination branch instead of the abandoned one.
- The new tests invoke real registered handlers and verify behavior, not just registration names.
- Public command names and extension surface area remained unchanged.
## Concerns
- No blocking concerns.
- Note: branch-local mode changes made via `/ctx-mode` are still persisted on the next `turn_end` snapshot. If a branch has no snapshot yet, restoration falls back to default branch state until a snapshot exists. This was left unchanged to keep the Task 6 fix focused.
