# Project Status - Delegate
**Date**: 2025-12-10
**Time**: 20:05
**Author**: Claude (AI Assistant)
**Session Context**: Code review, v0.3.2 release, critical hotfix v0.3.3

---

## Current Focus

### What We Were Working On
Comprehensive code review of the `fix/tech-debt-v0.3.2` branch using the `/devflow:code-review` workflow, followed by release preparation and an emergency hotfix for a broken npm package.

The session involved:
1. Running 8 parallel audit sub-agents (security, performance, architecture, tests, complexity, dependencies, documentation, typescript)
2. Synthesizing findings into PR comments and tech debt tracking
3. Reviewing and resolving 10 PR comments one-by-one with the user
4. Squash merging to main and triggering release
5. Discovering and fixing a critical build system bug that caused v0.3.2 to publish without compiled code
6. Releasing v0.3.3 hotfix and adding safeguards to prevent recurrence

### Problems Solved Today

1. **Missing JSDoc annotations** - Added `@since 0.3.2` tags to new interfaces
2. **Missing CHANGELOG entry** - Added concise v0.3.2 section documenting all changes
3. **Dead code accumulation** - Removed 3 unused/deprecated methods (`getQueueStats`, `getNextTask`, `requeueTask`)
4. **Broken npm package (CRITICAL)** - v0.3.2 published without `dist/` directory due to stale TypeScript cache
5. **Build system bug** - Clean script removed `.tsbuildinfo` but TypeScript creates `tsconfig.tsbuildinfo`
6. **Future-proofing** - Added prepublish safety check to prevent empty package publishing

### Decisions Made

| Decision | Rationale | Alternatives Considered |
|----------|-----------|------------------------|
| Skip pedantic JSDoc improvements | Current docs adequate, @since inconsistent elsewhere | Add full @example tags |
| Remove deprecated methods entirely | No callers, no removal timeline defined, dead code | Fix types and keep deprecated |
| Skip tests for maxChainDepth option | Trivial nullish coalescing, underlying logic tested | Add explicit passthrough test |
| Skip tests for CHECK constraint | Tests SQLite behavior, not our code | Add constraint validation tests |
| Add prepublish safety check | Prevents future broken releases | Rely on CI only |

## Architecture & Design

### Key Architectural Decisions This Session

1. **Dead code removal over deprecation maintenance** - Rather than fixing types on deprecated methods with no removal timeline, we removed them entirely. YAGNI principle.

2. **Defense-in-depth for npm publishing** - Added shell check `test -f dist/cli.js` in prepublishOnly to catch silent build failures before publishing.

3. **Minimal documentation updates** - Added CHECK constraint note inline rather than creating separate migration documentation. Code comments are sufficient for simple changes.

### Technology Stack
- **Runtime**: Node.js >= 20.0.0
- **Language**: TypeScript (strict mode)
- **Database**: SQLite with WAL mode (better-sqlite3)
- **Protocol**: MCP SDK v1.24.3
- **Testing**: Vitest with memory limits
- **Validation**: Zod at system boundaries

### Design Patterns in Use
- Event-driven architecture (EventBus)
- Factory pattern for handler creation
- Repository pattern for data access
- Result types for error handling
- Dependency injection via bootstrap

---

## Known Issues & Technical Debt

### Critical Issues
None currently. v0.3.3 resolved the broken package issue.

### Technical Debt (from audit)
- `tasks.status` and `tasks.priority` columns lack CHECK constraints
- Console.log usage instead of structured logger in some places
- Type assertions without runtime validation in row mapping

### TODOs in Codebase
Only 3 TODOs, all in test file for future SystemResourceMonitor enhancements:
- Threshold crossing event emission
- Threshold recovery event emission
- Threshold event de-duplication

---

## Agent Todo List State

**Note**: No active todo list this session - work was driven by PR comment review workflow.

### Session Work Pattern
Instead of TodoWrite tracking, this session used:
1. `/devflow:code-review` to generate PR comments
2. Sequential review of each comment with user
3. Fix/Skip decisions for each item
4. Release workflow with manual intervention for npm token issue

---

## Next Steps

### Immediate (Next Session)
- [ ] Update npm token in GitHub Secrets (currently expired)
- [ ] Verify v0.3.3 installation works: `npm install delegate@latest`
- [ ] Consider adding CHECK constraints to `status` and `priority` columns

### Short Term (This Week)
- [ ] Address remaining tech debt items from audit
- [ ] Review SystemResourceMonitor TODOs for implementation priority

### Long Term (This Month)
- [ ] Consider structured logging migration
- [ ] Evaluate runtime validation for database row mapping

## Context for Future Developer

### Things to Know
1. **npm test is blocked** - Use `npm run test:core`, `test:handlers`, etc. Full suite crashes Claude Code.
2. **TypeScript cache can cause issues** - If build seems stale, run `npm run clean` first.
3. **Release notes are required** - CI fails without `docs/releases/RELEASE_NOTES_v{version}.md`
4. **Prepublish check exists** - npm publish will fail if `dist/cli.js` missing

### Where to Start
- `CLAUDE.md` - Project-specific development guidelines
- `docs/architecture/` - System design documentation
- `.docs/audits/` - Detailed audit trails for recent work

### Key Files to Understand
- `src/core/events/events.ts` - All event type definitions
- `src/services/handlers/` - Event handler implementations
- `src/bootstrap.ts` - Dependency injection setup
- `package.json` scripts - Build and test commands

### Testing Strategy
- Run grouped tests: `npm run test:core`, `test:handlers`, `test:repositories`
- Never run `npm test` or `npm run test:all` in Claude Code
- Full suite only in local terminal or CI

## Raw Session Notes

### What the User Asked For
Run `/devflow:code-review` on the `fix/tech-debt-v0.3.2` branch, review findings, and prepare release.

### Approach Taken
1. Launched 8 audit sub-agents in parallel
2. Synthesized findings with 3 parallel synthesis agents
3. Presented 10 PR comments for individual review
4. Fixed 5 issues, skipped 5 low-value ones
5. Prepared release with squash merge
6. Discovered and fixed broken npm package
7. Released v0.3.3 hotfix
8. Added prepublish safety check

### Challenges Encountered
1. **npm token expired** - Had to use admin merge and manual release
2. **Broken npm package discovered** - v0.3.2 missing dist/ directory
3. **Root cause analysis** - Traced to wrong filename in clean script (`.tsbuildinfo` vs `tsconfig.tsbuildinfo`)

### Time Spent
- Estimated session duration: ~2 hours
- Complexity level: Complex (multiple phases, critical bug discovery)

## Final Thoughts

This session was a great example of why code review automation pays off - we caught a latent build system bug that had been waiting to cause problems. The `.tsbuildinfo` vs `tsconfig.tsbuildinfo` mismatch in the clean script is exactly the kind of subtle issue that's easy to miss in manual review but eventually causes production incidents.

The v0.3.2 broken package situation reinforces why we need defense-in-depth: the prepublish check we added will now catch this class of bug automatically. Always verify artifacts exist before publishing.

For anyone picking this up: the codebase is in good shape. The event-driven architecture is solid, tests are comprehensive, and technical debt is minimal. The main thing to watch is the npm token expiry - update it in GitHub Secrets when you can.

**Remember**: This is a snapshot in time. The project will have evolved since this was written. Use this as a starting point for understanding, not as gospel truth.
