Task 5 Fix Report

• Status: DONE
• Changes:
  • Updated .pi/agent/extensions/context-manager/src/runtime.ts to store the last observed token count, recompute lastZone whenever policy changes, and return a cloned policy from getPolicy().
  • Updated .pi/agent/extensions/context-manager/src/persist.ts to validate and sanitize snapshot data before restoring it, skip malformed newer snapshot entries, and preserve backward compatibility by keeping lastObservedTokens optional.
  • Expanded .pi/agent/extensions/context-manager/src/runtime.test.ts with zone recomputation, restore-policy, and no-alias policy/snapshot coverage.
  • Expanded .pi/agent/extensions/context-manager/src/persist.test.ts with malformed snapshot skipping and deep clone coverage.
  • Expanded .pi/agent/extensions/context-manager/src/summaries.test.ts with exact summary content and ordering assertions.
• Tests:
  • cd .pi/agent/extensions/context-manager && npx tsx --test src/runtime.test.ts src/persist.test.ts src/summaries.test.ts → 9 passed, 0 failed
  • cd .pi/agent/extensions/context-manager && npm test → 33 passed, 0 failed
• Files changed:
  • .pi/agent/extensions/context-manager/src/runtime.ts
  • .pi/agent/extensions/context-manager/src/persist.ts
  • .pi/agent/extensions/context-manager/src/runtime.test.ts

  • .pi/reviews/context-manager-task5-fix-report.md
• Self-review findings: The fix stays within Task 5 scope, keeps the existing runtime API surface intact, and adds regression coverage for each review finding that previously slipped through.
• Concerns: None.
