### [2026-04-11] v1.3.6: Scanner Redesign, Auto-OCR Countdown & save-version Automation
**Purpose:** Redesign the scanner UX for hands-free operation, enforce UI typography rules, add Item Type datalist, and create a reusable `save-version` AI command.
**Actions:**
- `frontend/components/Scanner.tsx` — Full layout redesign: controls moved below camera viewport (no overlay). Replaced manual OCR button with automatic 4-second OCR cycle. Added visual countdown with progress bar. Removed all `uppercase`/`tracking-widest` styling per AI_RULES Section 3.
- `frontend/components/AIOnboarding.tsx` — Added searchable `<datalist>` for Item Type field populated from existing DB types.
- `frontend/app/page.tsx` — Added searchable `<datalist>` for Item Type to the item edit modal.
- `frontend/app/inventory/page.tsx` — Added searchable `<datalist>` for Item Type in inventory catalog forms.
- `scripts/save_version.py` (NEW) — Automation script for `save-version` command: bumps patch version, commits, creates snapshot branch, generates prod ZIP.
- `AI_RULES.md` — Added Section 6 defining the `save-version` AI Command Shortcut.
- `README.md` — Updated Production Distribution section to document `save-version` workflow.
- `dev_docs/SESSION_STATE.md` — Updated with current session handover.
**Status:** Stable. Ready for version bump.

### [2026-04-11] v1.3.5: Frontend Login Loop Fix
**Purpose:** Fix infinite redirect loop after successful LDAP login (Chrome crash bug).
**Actions:**
- `frontend/lib/api.ts` — axiosInstance baseURL now lazy (set in request interceptor, not at module init) to fix SSR wrong-URL bug
- `frontend/lib/api.ts` — 401 interceptor now guards against redirect when already on `/login`
- `frontend/app/page.tsx` — token guard added to both useEffect hooks before any API calls
- `frontend/lib/auth.ts` — removed temporary debug console.log statements
- `frontend/app/login/page.tsx` — removed temporary debug console.log statements and unused `memo` import
- `dev_docs/SESSION_STATE.md` — updated with current status (fixes applied, not yet tested)
- `dev_docs/SESSION_HISTORY.md` — previous session archived
**Status:** Applied, not yet tested. Server must be restarted to verify.

### [2026-04-11 12:45] v1.3.0: Dockerization & Export Script
**Purpose:** Upgraded the system architecture to support seamless dual-mode execution (Dockerized or Bare-Metal/Local). Extracted data and logic persistence layers to external volumes (`/data`, `/logs`). Added a dedicated production compiler.
**Actions:**
- `backend/database.py` and `users.py` now support `DATA_DIR` environment overrides.
- Implemented `backend/logger.py` for standard Python rotating logs mapped to `/app/logs`.
- Next.js configured for `standalone` output mode to strictly optimize containerized PWA size.
- Orchestrated full environment with `docker-compose.yml`, using Caddy for local self-signed HTTPS termination.
- Created `export_prod.sh` to extract a clean release bundle without AI/Dev files (using optimized `rsync`).
**Modified Files:**
- `backend/database.py`
- `backend/routers/users.py`
- `backend/logger.py` (New)

### [2026-04-11 12:25] v1.2.8: Absolute Documentation Consolidation
**Purpose:** Restructured all project documentation to completely eliminate redundancy and establish clear "Single Source of Truth" boundaries for humans and AI agents.

- Created `PROJECT_ARCHITECTURE.md` uniting business requirements, tech stack, data models, and specific OCR algorithms.
- Unified all AI operational rules, constraints, and UI fidelities strictly inside `AI_RULES.md`.
- Removed redundant, overlapping files (`GEMINI.md`, `requirements.md`, `TECH_STACK.md`, `UI_FIDELITY_SPEC.md`, `SCANNER_LOGIC_SPEC.md`).
- Stripped `PLAN.md` down to just the active checklist.
**Modified Files:**
- `PROJECT_ARCHITECTURE.md` (New)
- `AI_RULES.md`
- `PLAN.md`
- `VERSION.json`

### [2026-04-11 12:15] v1.2.7: Documentation Refactor & Portability
**Purpose:** Consolidated technical stack information into a single source of truth (`dev_docs/TECH_STACK.md`) and removed absolute paths from all AI-facing documents to ensure the project can be moved across environments without breaking references.
**Modified Files:**
- `dev_docs/TECH_STACK.md` (New)
- `GEMINI.md` (Refined)
- `AI_RULES.md` (Cleaned)
- `PLAN.md` (Referenced tech stack)
