# AI Session State - HANDOVER

**Status**: Phase 3 Completed. Ready for Phase 4 (Frontend/PWA).
**Current AI Agent**: Gemini (Antigravity)
**Context**:
- **Backend**: Fully functional SQLite + FastAPI foundation. Supporting single/bulk check-in/out and trash operations.
- **Audit Logging**: Mandatory and immutable across all mutation endpoints.
- **Coordination**: Multi-AI Handover protocol established. `SESSION_STATE.md` (this file) and `SESSION_HISTORY.md` (archive) are ready.

**Technical Notes for next session**:
- Every mutation in `routers/operations.py` and `routers/items.py` triggers an `AuditLog` entry.
- `bulk-check-out` parses a list and performs individual item logging.
- PWA is the next big step. Needs to support offline barcode scanning using `html5-qrcode` and eventual `IndexedDB` sync.

**Next Steps**:
1. Initialize the Frontend project (using React/Next.js/Tailwind).
2. Establish the PWA manifest and Service Worker for offline support.
3. Build the Dashboard UI.
