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.
