Project Completion Handoff Report: HAD Digital MVP Skeleton

Author: Project Orchestrator (teamwork_preview_orchestrator) Working Directory: c:\AI Projects\Kais Project\.agents\orchestrator_1 Parent Agent: Sentinel (054c398b-33a9-46a8-a8f3-c9053411d877) Date: 2026-09-05T11:13:00Z Target Milestone: HAD Digital MVP Skeleton Build & Verification Gate Gate Verdict: PASS (Strict unanimous agreement across 2 Reviewers, 2 Challengers, and Forensic Auditor)

1. Observation

All requirements and acceptance criteria specified in ORIGINAL_REQUEST.md have been implemented, packaged, and verified:

1.1 Requirements Fulfillment

• R1: Standalone Executable Packaging:
• dist/HAD Digital.exe compiled as a single-file Windows executable via PyInstaller.
• File size: 9.78 MB (10,251,451 bytes), well below the 20 MB constraint.
• Zero external runtime dependencies on host machines (AST import scan verified 100% Python standard library).
• Storage Decoupling: Decoupled read-only bundle directory (sys._MEIPASS) from mutable persistent storage (had.db) via MVP/config_manager.py. Eliminates %TEMP% data loss on exit.

• R2: Foundational Core Features:
• Role-based authentication: hashlib.scrypt (N=16384, r=8, p=1, dklen=64) with 32-byte cryptographic hex salts and persistent 5-failure lockout (30 minutes). 8 roles supported: Oncologist (dr.martin), HAD Nurse (inf.moret), Patient (patient.durand), Admin (admin), etc.
• Patient toxicity reporting form: Supports both multi-symptom questionnaires and flat inputs, evaluating CTCAE v5.0 rules across 12 oncology symptoms, setting provisional flags for grades $\ge 2$, generating tiered alerts (Routine, Urgent, Emergency), and persisting directly to SQLite.
• Care timeline: Unified chronological stream displaying patient self-reports, clinician observations, CTCAE grades, and alert badges.

• R3: Responsive Local-First Frontend:
• Serves HTML5/CSS3/vanilla JS SPA shell from get_bundle_dir() / "static".
• Zero external CDN links; responsive design system; strict security headers (CSP, X-Content-Type-Options, X-Frame-Options).

• Acceptance Criteria:
• 04_Build/build_exe.py: Automated CLI script (--mode {onefile, onedir}, --clean, --verify) compiling the standalone binary in 5.2s.
• 05_Test/verify_mvp.py: Self-contained programmatic acceptance script using zero external dependencies, supporting both --source and --exe modes.
• Core Clinical Flow: Verified patient login, toxicity report submission, direct SQLite persistence, clinician login, and care timeline visibility.

1.2 Verification Metrics

• python 05_Test/verify_mvp.py --source: PASS (8/8 steps, 10 assertions in 0.81s).

• python 05_Test/verify_mvp.py --exe: PASS (8/8 steps, 10 assertions in 1.84s against dist/HAD Digital.exe).

• pytest 05_Test/: PASS (94/94 tests across Tiers 1–5 in 8.98s).

• python 05_Test/test_empirical_gate2.py: PASS (16/16 empirical probes).

• python 05_Test/stress_harness.py --all: PASS (59/59 assertions on source, 59/59 on .exe).

• Concurrency: 25 concurrent threads in SQLite WAL mode executed without database locks.

• Security: 10/10 path traversal attacks strictly blocked (HTTP 403/404); brute-force lockout persisted across process restarts.

2. Logic Chain

1. Phase 0 (Survey): Deployed 3 Explorers (spec_miner_survey_1, explorer_survey_2, explorer_survey_3) to comprehensively investigate specifications, architecture, packaging, and testing. Identified critical architectural requirements: PyInstaller _MEIPASS data-loss risk, ThreadingHTTPServer selection, and frontend login handler bug (data.ok).

1. Architecture & Scope: Synthesized PROJECT.md establishing the 35-item Feature Inventory, interface contracts, storage decoupling (get_bundle_dir vs get_data_dir), and 5 sequential/parallel milestones.

1. Dual-Track Execution:
• E2E Testing Track: test_writer_track_1 implemented 05_Test/ (94 tests across Tiers 1–5 + verify_mvp.py) and published TEST_INFRA.md and TEST_READY.md.
• Implementation Track: worker_m1_m2_1 implemented M1 & M2 (storage decoupling, REST API, login/timeline UI). worker_m3_1 implemented M3 (04_Build/build_exe.py and single-file HAD Digital.spec, compiling dist/HAD Digital.exe).

1. Verification Gate: Dispatched 5 concurrent gate agents:
• reviewer_gate_1: APPROVE (verified all acceptance criteria and E2E suites).
• reviewer_gate_2: APPROVE (verified zero-dependency AST, persistence across restart, WAL concurrency).
• challenger_gate_1: APPROVE (59/59 assertions on source & .exe, 101/101 automated tests).
• challenger_gate_2: APPROVE (25 concurrent threads in WAL mode, 10/10 path traversal attacks blocked).
• auditor_gate_1: CLEAN (zero hardcoded outputs, zero facade/dummy methods, authentic scrypt, SQLite, and PyInstaller logic).

1. Gate Verdict: All 4 gate criteria satisfied (strict AND). Final Gate Result: PASS.

3. Caveats & Recommendations

1. Unsigned Binary (Internal Prototype): The generated dist/HAD Digital.exe is unsigned. On fresh Windows installations, Windows Defender SmartScreen may display an "Unknown Publisher" prompt on first execution. Clicking "More info" -> "Run anyway" allows execution. For commercial hospital distribution, Authenticode code signing with an EV certificate should be added.

1. Session TTL Enforcement: Sessions are currently tracked via in-memory and database tokens. For production healthcare compliance (HIPAA / GDPR / French HDS), enforce strict rolling 15-minute inactivity timeouts.

1. Legacy Clean-up: Prototype files in 04_Build/ (database.py, server.py) from initial scaffolding are unreferenced by build_exe.py or HAD Digital.spec and can be safely removed or archived.

4. Conclusion

The HAD Digital MVP skeleton is completely built, packaged into a standalone Windows executable (dist/HAD Digital.exe), and comprehensively verified against all acceptance criteria. The project is ready for Sentinel Victory Audit.
