## Recent Achievements (Sprint 61)

### Pre-commit Hooks: Vaporware Eliminated ✅

**Problem**: pmat-book Chapter 9 documented commands that didn't exist
- ❌ `pmat hooks init` → Error: "unrecognized subcommand 'init'"
- ❌ `pmat hooks init --interactive` → Not available
- ❌ `pmat hooks run` → Not available

**Solution Delivered (v2.178.0)**:
- ✅ `pmat hooks init` - Alias for install (book line 40)
- ✅ `pmat hooks init --interactive` - Full interactive setup
- ✅ `pmat hooks run --all-files --verbose` - CI/CD integration
- ✅ Fixed UX bug: No more misleading backup messages

**Impact**:
- Documentation-reality gap eliminated
- 100% pmat-book Chapter 9 compatibility
- User trust restored
- Professional, polished experience
