Comprehensive Handoff Report: HAD Digital MVP Test & Verification Framework

Agent ID: explorer_survey_3 Date: 2026-09-05T10:36:00Z Target Milestone: HAD Digital MVP Test & Verification Architecture (Tiers 1–5 & Programmatic Verification Script) Parent Agent: orchestrator_1 (8c700e5d-87a4-4452-ab59-6fc2e8946b0d) Output Path: c:\AI Projects\Kais Project\.agents\explorer_survey_3\handoff.md

1. Observation

1.1 Test Asset Survey in 05_Test

  ### Automated Testing
  No automated tests are implemented in the MVP. This is a gap that should be addressed before production deployment.

1.2 Existing MVP Prototype Assets in c:\AI Projects\Kais Project\MVP

Inspection of c:\AI Projects\Kais Project\MVP revealed a complete Python web application:

1.3 Local Environment Tooling Survey

A probe of the host operating environment (Windows 11 / PowerShell, Python 3.14.6) established that the following testing packages are installed and functional:

1.4 Empirical Verification Results: Server Lifecycle & Core Flow

Empirical verification scripts were executed against both the Python source server (MVP/app.py) and the compiled binary (MVP/dist/HAD Digital/HAD Digital.exe) using dynamic port allocation and isolated temporary SQLite databases.

Test 1: Python Source Lifecycle & E2E Verification (app.py)

Test 2: Standalone Binary Lifecycle & E2E Verification (HAD Digital.exe)

Test 3: Adversarial Hardening Verification (Tier 5)

1.5 Defect Discovered in Web Frontend (MVP/static/app.js)

In MVP/static/app.js (lines 77–83):

const data = await api('POST', '/login', {
  username: document.getElementById('username').value,
  password: document.getElementById('password').value
});
if (data && data.ok) { currentUser = data.user; navigate('dashboard'); }
else document.getElementById('login-error').textContent = data.error || 'Login failed';

However, in MVP/app.py (line 199):

self._json_response({"message": "Login successful", "user": {k: user[k] for k in ("id", "username", "role", "display_name")}})

The backend returns message and user, but does not include an ok: true key. In app.js, data.ok evaluates to undefined (falsy), causing valid logins to hit the else branch and display "Login failed" in the browser UI.

2. Logic Chain

  1. Premise 1 (Acceptance Criteria per ORIGINAL_REQUEST.md):

The MVP acceptance criteria demand:

  • Packaging as a standalone .exe using PyInstaller.
  • A programmatic verification script testing process launch, authentication, health checks, and zero external runtime dependencies.
  • Patient login, toxicity report submission, SQLite persistence, and clinician login + care timeline verification.
    1. Premise 2 (Gap in Existing Assets):

    Observation 1.1 confirms that 05_Test is empty and automated tests were deferred in Phase 4G. Therefore, a complete test infrastructure, test tier hierarchy, and verification script must be formally designed and delivered to 05_Test.

    1. Premise 3 (Feasibility of Dual-Target Verification):

    Observations 1.4 (Test 1 and Test 2) prove empirically that both MVP/app.py and MVP/dist/HAD Digital/HAD Digital.exe accept CLI port flags (--port), respect environment variable overrides (HAD_PORT, HAD_DB_PATH), auto-seed baseline users in fresh SQLite databases, and support identical HTTP API contracts.

  • Inference: A single unified programmatic verification script (verify_mvp.py) can test both source code and the compiled .exe using standard Python library primitives (urllib.request, http.client, sqlite3, subprocess), guaranteeing that testing introduces zero runtime dependencies on the target .exe.
    1. Premise 4 (Test Tier Hierarchy Necessity):

    Simple happy-path testing is insufficient for medical software (oncology toxicity monitoring). A 5-tier testing structure is necessary:

  • Tier 1: Covers all 19 endpoints and 8 user roles (functional parity).
  • Tier 2: Covers CTCAE boundary thresholds (e.g. lab value cutoffs, severity 0–4), missing fields, and query bounds.
  • Tier 3: Covers the 8-role x 19-endpoint RBAC permission matrix and concurrent multi-symptom submission.
  • Tier 4: Simulates end-to-end clinical oncology patient journeys (e.g. Febrile Neutropenia emergency flow).
  • Tier 5: Proves resilience against adversarial attacks (5-fail lockout, path traversal, SQL injection, XSS/CSP, SQLite WAL concurrency).
    1. Premise 5 (Frontend Rectification Requirement):

    Observation 1.5 revealed that while the backend REST API functions perfectly, the vanilla JS frontend fails on login due to data.ok. Resolving this discrepancy must be scheduled as a high-priority bug fix in Milestone M2.

    3. Caveats

    1. Browser GUI Automation vs API Testing: Playwright (v1.62.0) is installed in the Python environment, but headless browser binaries (e.g. Chromium) were not executed to avoid creating heavy background browser processes during read-only survey. The primary verification framework is designed around headless HTTP/API testing, which is fast, deterministic, and does not require GPU/browser runtimes.
    1. PyInstaller Antivirus / Code Signing: HAD Digital.exe compiles and runs cleanly on this Windows 11 host. However, in corporate or clinical environments, unsigned PyInstaller binaries can trigger false positives in Windows Defender or enterprise EDRs. Code-signing or folder bundle mode (Mode B) remains a deployment consideration post-MVP.
    1. AI Adapter Mocking: The AI chat endpoint /api/chat currently uses StubAdapter. External LLM providers (e.g., GLM-4) require network API keys and should be tested via mock adapters during offline automated test runs.
    1. Scope Boundaries: As an explorer agent, no source code or test files were written to 05_Test or MVP/. All architectures, specifications, and scripts are documented in this report for immediate implementation by Builder agents.

    4. Conclusion

    1. Feasibility Confirmed: The HAD Digital MVP is structurally sound. The compiled HAD Digital.exe and source app.py both satisfy the core acceptance criteria of autonomous launch, role-based authentication, toxicity report submission, SQLite persistence, and clinician timeline display.
    1. Deliverable Architecture for 05_Test:
      • 05_Test/verify_mvp.py: A standalone, zero-external-dependency programmatic verification script that validates the full acceptance lifecycle against either app.py or HAD Digital.exe.
      • 05_Test/pytest.ini & 05_Test/conftest.py: A robust test harness supporting test tiers 1 through 5, dynamic port allocation, database isolation, and role-based session fixtures.
      • Full test suites organized under 05_Test/unit/, 05_Test/integration/, 05_Test/e2e/, and 05_Test/security/.
    1. Critical Defect Logged: MVP/static/app.js line 81 requires a one-line update (if (data && (data.ok || data.user)) or backend returning {"ok": True, ...}) to enable UI login.

    5.2 Programmatic Verification Script Design (verify_mvp.py)

    The verification script must be completely self-contained and run on any machine with Python standard library. Below is the complete implementation design:

    """HAD Digital MVP - Standalone Programmatic Verification Script.

Validates the complete acceptance criteria per ORIGINAL_REQUEST.md:
1. Automated launch of application (Source or .exe) with dynamic port allocation
2. Startup health check and unauthenticated ping
3. Invalid credential rejection
4. Patient authentication and session cookie issuance
5. Patient toxicity report submission with auto-grading
6. Programmatic SQLite direct database inspection (persistence verification)
7. Clinician authentication (Oncologist)
8. Clinician care timeline verification
9. Graceful process shutdown and port cleanup

Usage:
    python verify_mvp.py --mode source [--app-path MVP/app.py]
    python verify_mvp.py --mode exe    [--exe-path "MVP/dist/HAD Digital/HAD Digital.exe"]

    5.3 Test Tier Hierarchy Specification (Tiers 1 to 5)

    Tier 1: Feature Coverage (Nominal Contract & Happy-Path Validation)

    Objective: Validate that 100% of core features and all 19 REST endpoints behave strictly per API_Contract.md.

    Tier 2: Boundary & Corner Cases (Extreme Inputs & Edge Conditions)

    Objective: Validate input validation, boundary handling, and error resilience without application panics.

    Tier 3: Combinations & Matrix Testing (Multi-Dimensional RBAC & Concurrency)

    Objective: Validate multi-user interactions, role boundaries, and concurrent event handling.

    Tier 4: Real-World Clinical Scenarios (End-to-End Persona Journeys)

    Objective: Replicate complete clinical workflows across chemotherapy cycles.

    Tier 5: Adversarial Hardening (Security & Chaos Testing)

    Objective: Probe system boundaries against malicious exploitation, brute force, and crash conditions.

    5.4 Implementation Plan for Testing Infrastructure in 05_Test

    To operationalize this design, the following action items are assigned to Phase 1 / Implementation Workers:

    1. Scaffold 05_Test layout: Create directories unit/, integration/, e2e/, security/.
    1. Deploy verify_mvp.py: Write the zero-dependency verification script into 05_Test/verify_mvp.py and create root symlink or wrapper verify_acceptance.py.
    1. Deploy Pytest Framework:
      • Write 05_Test/conftest.py with fixtures for isolated_db, server_port, server_process, and api_client.
      • Write 05_Test/pytest.ini with custom markers (tier1, tier2, tier3, tier4, tier5, exe).
    1. Fix Frontend UI Bug: Update MVP/static/app.js (line 81) to accept (data && (data.ok || data.user)) or update MVP/app.py line 199 to return {"ok": True, ...}.

    6. Verification Method

    To independently verify the findings in this report, execute the following commands in the workspace root:

    1. Verify Empty 05_Test Directory:
       Get-ChildItem -Path "c:\AI Projects\Kais Project\05_Test"
   # Confirms 0 files exist
    1. Verify Python & Standalone Executable Existence:
       python --version
   Test-Path "c:\AI Projects\Kais Project\MVP\app.py"
   Test-Path "c:\AI Projects\Kais Project\MVP\dist\HAD Digital\HAD Digital.exe"
   # Both return True
    1. Verify Programmatic Acceptance Criteria on Python Source:

    Run the inline probe validating launch, patient submit, SQLite DB row, and clinician timeline:

       python -c "
   import socket, subprocess, time, sys, requests, os, tempfile, shutil, sqlite3
   td = tempfile.mkdtemp(); db = os.path.join(td, 't.db')
   s = socket.socket(); s.bind(('127.0.0.1', 0)); p = s.getsockname()[1]; s.close()
   proc = subprocess.Popen([sys.executable, 'MVP/app.py', '--port', str(p)], cwd='.', env=dict(os.environ, HAD_DB_PATH=db, HAD_PORT=str(p)))
   try:
       time.sleep(1)
       sp = requests.Session()
       assert sp.post(f'http://127.0.0.1:{p}/api/login', json={'username':'patient.durand','password':'demo123'}).status_code == 200
       r = sp.post(f'http://127.0.0.1:{p}/api/reports', json={'patient_id':1,'symptom_id':'nausea','symptom_category':'gastrointestinal','severity_score':2}).json()
       rid = r['report_id']
       conn = sqlite3.connect(db); assert conn.cursor().execute('SELECT id FROM toxicity_reports WHERE id=?', (rid,)).fetchone(); conn.close()
       so = requests.Session()
       assert so.post(f'http://127.0.0.1:{p}/api/login', json={'username':'dr.martin','password':'demo123'}).status_code == 200
       tl = so.get(f'http://127.0.0.1:{p}/api/timeline', params={'patient_id':1}).json()
       assert any('nausea' in e['title'].lower() for e in tl['events'])
       print('VERIFICATION SUCCESSFUL')
   finally:
       proc.terminate(); proc.wait(5); shutil.rmtree(td, ignore_errors=True)
   "
    1. Verify Programmatic Acceptance Criteria on Standalone Binary:

    Run the identical probe with the target pointing to MVP/dist/HAD Digital/HAD Digital.exe. Confirms identical pass results.

    1. Verify Front-End Mismatch:

    Inspect line 81 of MVP/static/app.js and line 199 of MVP/app.py to confirm the data.ok vs {"message": ...} discrepancy.
