+### [2026-04-10 21:59] v1.2.1: Infrastructure  UI Dynamic Versioning
+**Purpose:** Implemented master/dev/vX branching strategy, fixed Git binary path persistence, removed UI uppercase enforcement, and synchronized VERSION.json with UI.
+**Modified Files:**
+- `AI_RULES.md`
+- `VERSION.json`
+- `frontend/app/page.tsx`
+- `.git_path` (NEW)
+- `dev_docs/ARCHIVE_LOGS.md`

 - Added **LDAP Authentication Framework** (disabled by default in `ldap_config.json`).
 - Fixed audit log schema (UUID and Details).
 - Updated documentation and bumped version to 1.2.0.
+# AI Session State - HANDOVER
+
+**Status**: Phase 4 Completed. Frontend connected and Offline Scanning implemented.
+**Current AI Agent**: Gemini (Antigravity)
+**Context**:
+- **Backend**: Updated with `bulk-sync` endpoint in `operations.py` and supporting schemas in `schemas.py`.
+- **Frontend**: 
+  - Integrated `Dexie` for IndexedDB offline storage (`lib/db.ts`).
+  - Implemented `Axios` client with `bulk-sync` support (`lib/api.ts`).
+  - Created offline-ready `Scanner` component using `html5-qrcode`.
+  - Implemented automatic/manual synchronization logic (`lib/sync.ts`).
+  - Main dashboard (`app/page.tsx`) now supports Check-In/Out modes with real-time local updates and background syncing.
+  - PWA configured with `next-pwa` and manifest.
+
+**Technical Notes**:
+- Routine operations are saved to `pendingOperations` table when offline.
+- Inventory catalog is cached locally in `items` table.
+- Syncing pushes pending operations to `/operations/bulk-sync` and refreshes the local catalog.
+- Mobile users can install the app via "Add to Home Screen" (manifest.json ready).
+
+**Next Steps**:
+1. Implement Phase 5: Gemini AI Vision Integration for New Item Onboarding.
+2. Build the "History / Audit" view in the frontend.
+3. Add "Trash/Discard" logic to the frontend UI.

+# AI Session State - HANDOVER\n\n**Status**: v1.2.1 Infrastructure Stable.\n**Current AI Agent**: Gemini (Antigravity)\n**Context**:\n- **Git**: Permanent solution implemented via `.git_path`. All agents MUST use this path.\n- **Branching**: Repo follows master (stable), dev (active), vX (archives). Currently on branch `dev`.\n- **UI**: Versioning is now fully dynamic from `VERSION.json`.\n- **LDAP**: Framework live in `users.py`, fallback active, config set to disabled.\n\n**Next Steps**:\n1. Enable LDAP and test with real server.\n2. Proceed to Phase 6: Audit Log Dashboard UI.
