# Current Session State

## 🎯 Active Goal
Phase 1 stability and optimization complete.

## ✅ Completed
- Initial Phase 1 feature set (Trello, Todoist, Obsidian, PlanToEat)
- AI Snapshot endpoint implementation (`/api/claude/snapshot`)
- Basic testing suite (9/9 passing)
- **Security Fix:** Timing attack vulnerability in Bearer token validation (ai_auth.go:33)
- **Security Fix:** JSON injection in error responses (ai_auth.go:47-50)
- **Database Hardening:** Enabled WAL mode for better concurrency (sqlite.go:32-35)
- **Database Hardening:** Set MaxOpenConns(1) to prevent "database is locked" errors (sqlite.go:38)
- **Security Fix:** SQL injection vulnerability in GetNotes LIMIT clause (sqlite.go:215-221)
- **Commit:** 4c03e9c "Harden database security and reliability"
- **Security Fix:** Path traversal mitigation - skip symbolic links in Obsidian scanner (obsidian.go:54-57)
- **Commit:** 325811c "Mitigate path traversal risk in Obsidian scanner"
- **Performance Optimization:** Parallelized Trello card fetching with semaphore-limited concurrency (trello.go:197-220)

## 🏗️ Architecture & Decisions
- **Decision:** Use SQLite for caching with a 5-minute TTL.
- **Decision:** Trello is the primary task system, requiring Key+Token auth.
- **Decision:** Agent endpoint uses Bearer token auth for security.
- **Decision:** Limit Trello concurrent requests to 5 to prevent API rate limiting.

## 📋 Next Steps
1. **Code Quality:** Commit parallelization changes.
2. **Testing:** Add unit tests for security fixes (timing attack, SQL injection, path traversal).
3. **Future:** Consider Phase 2 features (write operations, user management).

## ⚠️ Known Blockers / Debt
- **Test Coverage:** Security fixes lack dedicated unit tests.
