# AI AGENT RULES - MANDATORY SSOT ENTRY POINT

**READ THIS ENTIRE FILE BEFORE EXECUTING ANY TASK.**
This is the **Single Source of Truth** for ALL AI agents. Refer to [PROJECT_ARCHITECTURE.md](PROJECT_ARCHITECTURE.md) for technical logic.

---

## 1. AI MEMORY, TRACEABILITY & HANDOVER
- **MANDATORY STARTUP**: Read `dev_docs/SESSION_STATE.md` immediately at session start.
- **PLAN RETIREMENT**: Mark a completed "Master Plan" as `[COMPLETED]` in the file itself. Move technical details to `dev_docs/ARCHIVE_LOGS.md` and `PLAN.md` entries to `dev_docs/PLAN_HISTORY.md`.
- **STRICT HANDOVER**: Update `dev_docs/SESSION_STATE.md` at the end of every task with: **Active AI**, **Current Status**, **Context**, and **Next Steps**.
- **SESSION ARCHIVE**: Move previous handover content to `dev_docs/SESSION_HISTORY.md` before writing new state.
- **NO INTERACTION OVERLAP**: Never modify a file if another AI session is explicitly working on it.
- **CONCISE COMMUNICATION**: Be concise! Do not explain a thousand details unless they are absolutely necessary.

## 2. ENGINEERING & OPERATIONAL LAWS
- **ENGLISH ONLY**: Interfaces, code, variables, and docs MUST be in English. Translate any Romanian text found in code immediately.
- **GIT PROTOCOL**: Use system `git`. Never push or use `--force` unless explicitly asked.
- **VERSIONING**: Update `VERSION.json` on every commit using `scripts/save_version.py`.
- **SSOT INTEGRITY**: Every feature change MUST update: `README.md`, `USER_GUIDE.md`, `PROJECT_ARCHITECTURE.md`, `DEPLOYMENT.md`, and `dev_docs/PLAN.md`.
- **CODE QUALITY**: Files under 300 lines, complexity < 10, strict Single Responsibility Principle.

## 3. UI/UX "PREMIUM" FIDELITY STANDARDS
- **Aesthetics**: Density must remain "Premium". Use Tailwind CSS. NO simplification.
- **Typography Rules**:
  - **NO UPPERCASE** or **NO ITALICS** in any UI context (headers, labels, buttons).
  - **NO BOLD FONTS**: Use `font-normal` throughout. Hierarchy via size and color only.
  - **NO `tracking-widest`**.
- **Layout**: Main pages MUST use `max-w-7xl`.
- **Unified Headers**: Icon box (`p-4 bg-primary/10 border-primary/20`) + Title (`text-3xl font-normal`).
- **Iconography**: Use **Lucide Icons** exclusively.

## 4. REFACTORING & TESTING STRATEGY (MANDATORY)
- **TEST-FIRST**: All tests must be written and passing BEFORE refactoring any code.
- **ZERO REGRESSION**: 100% of existing tests must pass post-refactor.
- **GATING**:
  - **Backend**: Pytest coverage target 85%+ (`backend/tests/`).
  - **Frontend**: Vitest coverage target 80%+ (`frontend/tests/`).
  - **E2E**: Critical workflows in Playwright (`frontend/e2e/`).
- **MODULARITY**: Break monolithic files into focused modules (<300 lines). Extract logic into hooks/services.

## 5. DATA INTEGRITY & SECURITY POLICY
- **RESTRICTED ACTIONS**: Destructive actions (DELETE) require Admin role.
- **AUDIT IMMUTABILITY**: Deleting an item MUST NOT delete its audit log.
- **NO AUTH BYPASS**: Authentication is NEVER disabled in any environment.
- **TRIPLE CONFIRMATION**: Deleting critical entities requires 3 confirmations.
- **NATIVE ALERTS**: Use `window.confirm` for destructive UI actions.
- **CREDENTIALS**: initialized via migrations/scripts. NEVER hardcoded or logged.

## 6. AI COMMAND SHORTCUTS
- **`save-version`**: 
  0. **MANDATORY**: Update ALL documentation with explanations of current changes.
  1. Increment `VERSION.json`.
  2. Git add/commit (`Build [vX.Y.Z]`). 
  3. Create snapshot branch.
  4. Merge into `master`.
  5. Run `./export_prod.sh`.
  (Command: `python3 scripts/save_version.py`).
