## 3. PENDING WORK ANALYSIS

### TODOs/FIXMEs in Source Code
**Status**: ZERO found in `/src/` directory

All code is clean of TODO/FIXME/HACK markers. The project has excellent code discipline.

### Known Issues (GitHub)
- **Issue #31**: Tech Debt Backlog (open tracking item)
  - Assigned to: [tracking previous work items]
  - Status: [references Issue #31 for continued monitoring]

### Recent Fixes Applied (Last Session)
1. **Zod Validation Performance** - switched from `safeParse()` to `parse()` (10-15% improvement)
2. **Type Safety** - Created `DisposableService` interface (replaces `as any` casts)
3. **Test Code in Production** - Moved `NoOpProcessSpawner` to `tests/fixtures/`
4. **CI Failure** - Updated corruption test to verify CHECK constraints
5. **Documentation** - Added JSDoc for `AUTOBEAT_DATABASE_PATH` env var

### Technical Debt (Tracked)
- **HIGH**: None active (v0.3.2-0.3.3 addressed major items)
- **MEDIUM**: Timing-based waits (40+ locations) - deferred to v0.4.0
- **LOW**: Event-driven refactoring - planned architectural improvement
