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.
