# Session Memory: STORY-342

## Observations

### Phase 02 (Test-First)
- [success] All 7 AC tests generated (8 test files total)
- [pattern] Bash shell tests work well for file existence and schema validation
- [success] Tests verified RED state - files don't exist yet

### Phase 03 (Implementation)
- [success] Created .claude/memory/learning/ directory per ADR-014
- [success] Created 3 learning files: tdd-patterns.md, friction-catalog.md, success-patterns.md
- [success] Created post-qa-memory-update.sh hook with pattern detection logic
- [success] Registered hook in hooks.yaml
- [success] All 7 AC tests now GREEN

### Phase 04 (Refactoring)
- [success] Shell script complexity acceptable (~6, below threshold of 10)
- [success] Security fix: Added STORY_ID format validation to prevent path traversal
- [success] Code review approved with suggestions (non-blocking)
- [pattern] DRY improvement opportunity identified (shared confidence levels)
