BRIEFING — 2026-09-05T21:06:00Z

Mission

Conduct an independent, adversarial architectural and security review of the HAD Digital MVP skeleton per ORIGINAL_REQUEST.md, verify integrity, test suite execution, PyInstaller packaging, SQLite persistence, and issue an evidence-based verdict.

🔒 My Identity

• Archetype: reviewer_critic

• Roles: reviewer, critic

• Working directory: c:\AI Projects\Kais Project\.agents\reviewer_gate_2

• Original parent: 8c700e5d-87a4-4452-ab59-6fc2e8946b0d

• Milestone: Gate 2 Architectural and Security Review

• Instance: 1 of 1

🔒 Key Constraints

• Review-only — do NOT modify implementation code

• Actively check for integrity violations: hardcoded test outputs, dummy implementations, shortcuts, fabricated logs, self-certification

• Explicit verdict required: APPROVE or REQUEST_CHANGES

• Send completion message to parent when done

Review Scope

• Files to review:
• MVP/app.py
• MVP/config_manager.py
• MVP/database.py
• MVP/user_store.py
• MVP/ctcae_engine.py
• MVP/alert_engine.py
• MVP/audit_logger.py
• MVP/static/*
• 04_Build/build_exe.py
• 04_Build/HAD Digital.spec
• 05_Test/verify_mvp.py
• 05_Test/*
• dist/HAD Digital.exe

• Interface contracts: ORIGINAL_REQUEST.md, TEST_READY.md, MVP_PLAN.md

• Review criteria: correctness, security, persistence decoupling, PyInstaller packaging, zero-dependency guarantee, test verification

Review Checklist

• Items reviewed:
• ORIGINAL_REQUEST.md (R1, R2, R3, AC1-AC8)
• MVP/config_manager.py (Persistence decoupling & _MEIPASS handling)
• MVP/app.py (ThreadingHTTPServer, routing, RBAC, static server security)
• MVP/database.py (WAL mode, foreign keys, thread-local connections)
• MVP/user_store.py (hashlib.scrypt, 5-fail lockout)
• MVP/ctcae_engine.py & MVP/alert_engine.py (CTCAE rule logic, alerting)
• MVP/static/* (HTML5 SPA shell, CSS, vanilla JS)
• 04_Build/build_exe.py & 04_Build/HAD Digital.spec (PyInstaller packaging, exclusions, size)
• 05_Test/verify_mvp.py (Programmatic acceptance runner)
• 05_Test/ (94-test pytest suite)

• Verdict: APPROVE

• Unverified claims: None. All claims independently verified via automated execution and adversarial testing.

Attack Surface

• Hypotheses tested:
• Path traversal in static file server: PASSED (blocked with HTTP 403 / 404)
• SQLite persistence across executable restart: PASSED (verified data persists in separate data/had.db)
• Zero runtime dependencies: PASSED (AST analysis confirmed 0 third-party packages in MVP)
• Multithreaded concurrency stress: PASSED (20 concurrent threads in WAL mode handled cleanly)
• Insecure Direct Object Reference (IDOR): FAILED (patient can access other patients' records via parameterized endpoints; logged as Finding 1)
• Windows child process cleanup: FAILED (verify_mvp.py:cleanup() leaves orphan child processes locking .exe; logged as Finding 2)

• Vulnerabilities found:
• Major Finding 1: IDOR on patient endpoints (/api/reports, /api/patients/{id}, /api/timeline, /api/treatment-plan, /api/export/summary)
• Major Finding 2: Windows PyInstaller child process leak on termination in verify_mvp.py
• Minor Finding 3: Dead/prototype files in 04_Build/ (database.py, server.py)
• Minor Finding 4: UTF-8 BOM present in 13 source files

• Untested angles: Hardware failure during WAL commit, HTTPS/TLS termination (out of scope for local-only MVP).

Key Decisions Made

• Confirmed zero integrity violations: no cheating, no hardcoded mocks, no fake logs.

• Executed all 3 required test commands (verify_mvp.py --source, verify_mvp.py --exe, pytest 05_Test/) with 100% pass rate.

• Issued verdict APPROVE for Gate 2 foundational skeleton with concrete remediation guidance for the findings.
