Addresses code review feedback:
✅ P0 (Must Fix):
- Fix JSONL lookup to return LAST match, not FIRST (resurrection.go:160-162)
- Changed from early return to scan all matches and keep last
- Respects JSONL append-only semantics
✅ P1 (Should Fix):
- Add test for multiple JSONL versions
- TestTryResurrectParent_MultipleVersionsInJSONL verifies correct behavior
- Document error message change in CHANGELOG.md
- Old: "parent issue X does not exist"
- New: "parent issue X does not exist and could not be resurrected from JSONL history"
- Marked as breaking change for script parsers
✅ P2/P3 (Nice to Have):
- Add documentation to AGENTS.md explaining auto-resurrection behavior
- Document best-effort dependency resurrection
⏸️ Deferred (P1 - Optimize batch resurrection):
- Caching optimization deferred (no batch use cases currently)
All tests pass:
- Unit tests: internal/storage/sqlite/
- Integration test: TestImportWithDeletedParent
