Step Checklist

• [x] Initial dispatch received and logged

• [x] BRIEFING.md established with 🔒 identity and constraints

• [x] Inspect existing implementation and test harness (MVP/app.py, 04_Build/*, 05_Test/verify_mvp.py, 05_Test/test_e2e_tier5_adversarial.py)

• [x] Probe 1: Standalone packaging integrity (dist/HAD Digital.exe launch on ephemeral port from arbitrary directory with zero env vars) — PASS

• [x] Probe 2: Security boundaries (path traversal, XSS injection sanitization, HTTP security headers) — PASS (10/10 blocked)

• [x] Probe 3: Brute force defense (5-strike threshold, 30-minute lockout enforcement, audit log logging, restart persistence) — PASS

• [x] Probe 4: Concurrency stress test (25 concurrent write/read threads against standalone exe with SQLite WAL validation) — PASS (25/25 in 0.57s)

• [x] Probe 5: Port conflict & dynamic binding resilience (behavior when requested port is occupied vs free) — PASS

• [x] Full regression verification: pytest 05_Test (99/99 passed in 24.28s) and verify_mvp.py --exe (8/8 steps passed in 1.84s)

• [x] Compile empirical evidence and document handoff.md with APPROVE verdict
