# BRIEFING — 2026-09-05T20:59:37+10:00

## Mission
Perform an independent, rigorous code and system review for the HAD Digital MVP skeleton per ORIGINAL_REQUEST.md, PROJECT.md, and TEST_READY.md, including verifying against integrity violations and issuing an evidence-based APPROVE/REQUEST_CHANGES verdict.

## 🔒 My Identity
- Archetype: reviewer_critic
- Roles: reviewer, critic
- Working directory: c:\AI Projects\Kais Project\.agents\reviewer_gate_1
- Original parent: 8c700e5d-87a4-4452-ab59-6fc2e8946b0d
- Milestone: Gate Review
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Actively check for integrity violations: hardcoded test results, facade implementations, shortcuts, fabricated verification, self-certifying work
- Must independently run verification commands
- Files for content delivery; Messages for coordination

## Review Scope
- **Files to review**:
  - `ORIGINAL_REQUEST.md`, `TEST_READY.md`, `01_System/API_Contract.md`, `03_Registers/Requirements_Register.md`
  - `MVP/` (`app.py`, `config_manager.py`, `database.py`, `user_store.py`, `ctcae_engine.py`, `alert_engine.py`, `static/app.js`, `static/index.html`)
  - `04_Build/` (`build_exe.py`, `HAD Digital.spec`, `dist/HAD Digital.exe`)
  - `05_Test/` (`verify_mvp.py`, `test_e2e_tier1.py` ... `test_e2e_tier5_adversarial.py`)
- **Interface contracts**: `01_System/API_Contract.md`, `ORIGINAL_REQUEST.md`
- **Review criteria**: Correctness, completeness, robustness, contract conformance, security, zero external runtime dependency, adversarial edge cases, integrity violation checks

## Review Checklist
- **Items reviewed**:
  - [x] ORIGINAL_REQUEST.md, TEST_READY.md, and API Contracts
  - [x] MVP Backend & Security Architecture (`app.py`, `user_store.py`, `database.py`)
  - [x] CTCAE & Alert Rules Engine (`ctcae_engine.py`, `alert_engine.py`, `ctcae_rules.json`)
  - [x] Frontend UI & Responsiveness (`index.html`, `app.css`, `app.js`)
  - [x] Build Pipeline & PyInstaller Spec (`build_exe.py`, `HAD Digital.spec`, `dist/HAD Digital.exe`)
  - [x] Test Suites & verify_mvp.py (`verify_mvp.py`, 5 tiers of pytest)
  - [x] Independent Command Executions (`verify_mvp.py --source`, `--exe`, `pytest 05_Test/`)
- **Verdict**: APPROVE
- **Unverified claims**:
  - None remaining. All tested independently with zero failures.

## Attack Surface
- **Hypotheses tested**:
  - [x] CTCAE grades or alert classifications hardcoded: DISPROVED (rules engine dynamically calculates thresholds from ctcae_rules.json).
  - [x] SQLite connection leaks or thread concurrency: TESTED (20 threads concurrent submissions passed with WAL mode).
  - [x] Auth bypass via crafted sessions or token injection: TESTED (fake UUID, malformed cookie, SQL injection in login rejected).
  - [x] Inactivity timer client-side vs server-side bypass: TESTED (identified that server lacks created_at TTL validation in _get_session; noted as finding).
  - [x] Input validation escapes in toxicity submission or patient registration: TESTED (handled safely; non-int query params raise 500 instead of 400; noted as finding).
- **Vulnerabilities found**:
  - Unused legacy prototype `04_Build/server.py` containing mock grading.
  - Server-side session dictionary lacks automatic TTL expiration/eviction.
- **Untested angles**:
  - Long-term multi-day session persistence under continuous load (beyond scope of MVP).

## Key Decisions Made
- Confirmed zero integrity violations across MVP and testing infrastructure.
- Validated standalone executable (.exe) launch and execution on native Windows without host dependencies.
- Issued APPROVE verdict with clear architectural improvement suggestions.
