# BRIEFING — 2026-09-05T10:31:00Z

## Mission
Investigate test assets in 05_Test, formulate E2E testing framework, programmatic verification script design, and test tier hierarchy (Tiers 1-5) validating HAD Digital MVP core acceptance criteria.

## 🔒 My Identity
- Archetype: explorer
- Roles: investigation, synthesis
- Working directory: c:\AI Projects\Kais Project\.agents\explorer_survey_3
- Original parent: 8c700e5d-87a4-4452-ab59-6fc2e8946b0d
- Milestone: HAD Digital MVP Test & Verification Architecture

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- Write only to your folder (`c:\AI Projects\Kais Project\.agents\explorer_survey_3`)
- Produce structured 5-component handoff report to `c:\AI Projects\Kais Project\.agents\explorer_survey_3\handoff.md`
- No source code or test write permission outside `.agents/explorer_survey_3`

- Updated: not yet

## Investigation State
- **Explored paths**: `ORIGINAL_REQUEST.md`, `DISPATCH.md`, `05_Test` (empty), `MVP/` (complete code prototype + compiled exe), `00_Governance/Project_Status.md`, `02_Requirements/`, `03_Architecture/API_Contract.md`, `03_Architecture/Database_Schema.md`, `MVP_EXECUTION_PLAN.md`.
- **Key findings**:
  1. `05_Test` is empty; no automated test assets currently exist in the repository.
  2. The MVP prototype in `MVP/` is complete, functional, and already compiled to `MVP/dist/HAD Digital/HAD Digital.exe`.
  3. Empirically validated dynamic port allocation, health check ping, and process shutdown for both Python server (`app.py`) and compiled `.exe`.
  4. Empirically validated full E2E workflow: patient login (`patient.durand`) -> report submission -> SQLite persistence (`toxicity_reports`, `toxicity_grades`) -> clinician login (`dr.martin`) -> care timeline verification (`GET /api/timeline?patient_id=1`).
  5. Empirically validated Tier 5 defenses: brute-force 5-fail lockout (account locks for 30 min) and path traversal blocking on `/static/`.
  6. Discovered client-side defect in `static/app.js` line 81: `data.ok` is checked, but `app.py` returns `{"message": "Login successful", "user": ...}` without `ok: true`, causing login button in UI to display error despite 200 HTTP response.
- **Unexplored areas**: None regarding core test scope. Ready to formulate comprehensive testing architecture and handoff report.

## Key Decisions Made
- Designed dual-mode programmatic verification script (`verify_mvp.py`) using Python standard library (with optional requests fallback) capable of testing both source `app.py` and standalone `HAD Digital.exe`.
- Designed 5-tier test architecture: Tier 1 (Feature Coverage), Tier 2 (Boundary/Corner Cases), Tier 3 (Combinations & RBAC Matrix), Tier 4 (Clinical Real-World Scenarios), Tier 5 (Adversarial Hardening & Resilience).
- Formulated recommended `05_Test` directory structure and pytest harness configuration.
