# BRIEFING — 2026-09-05T10:55:00Z

## Mission
Implement Milestone M3: Packaging & Build Automation for the HAD Digital MVP skeleton per ORIGINAL_REQUEST.md, PROJECT.md, and DISPATCH.md.

## 🔒 My Identity
- Archetype: worker
- Roles: implementer, qa, specialist
- Working directory: c:\AI Projects\Kais Project\.agents\worker_m3_1
- Original parent: 8c700e5d-87a4-4452-ab59-6fc2e8946b0d
- Milestone: M3 (Packaging & Build Automation)

## 🔒 Key Constraints
- Exclusive write ownership: 04_Build/*, PyInstaller spec files, dist/*. Do NOT modify files in 05_Test/ or MVP/.
- Standalone single-file Windows executable (.exe) using PyInstaller bundling Python web server, embedded SQLite, HTML5/CSS3/vanilla JS frontend, CTCAE rules, guidance, requiring zero external dependencies on host machine.
- Exclude bloat packages (pandas, numpy, playwright, pytest, torch, PIL, etc.) to keep binary lean (<20 MB).
- Verify standalone executable with `python 05_Test/verify_mvp.py --exe`.
- Mandatory integrity: No hardcoded test results, no facade implementations, genuine build and verification.
- Document all build commands, output binary size, and programmatic verification results in `handoff.md`.

## Task Summary
- **What to build**: `04_Build/build_exe.py` and `04_Build/HAD Digital.spec` to automate single-file packaging of `HAD Digital.exe` into `dist/HAD Digital.exe` (and `04_Build/dist/HAD Digital.exe`), then verify against `05_Test/verify_mvp.py --exe`.
- **Success criteria**: Automated build script compiles standalone .exe without errors, binary size < 20 MB, all acceptance tests in `05_Test/verify_mvp.py --exe` pass cleanly.
- **Interface contracts**: `.agents/orchestrator_1/PROJECT.md`, `03_Architecture/API_Contract.md`, `03_Architecture/Database_Schema.md`.
- **Code layout**: `04_Build/build_exe.py`, `04_Build/HAD Digital.spec`, `dist/HAD Digital.exe`.

## Key Decisions Made
- Use PyInstaller 6.22.2 to compile `MVP/app.py` into a single-file executable named `HAD Digital.exe`.
- Bundle `MVP/static` -> `static`, `MVP/guidance` -> `guidance`, and `MVP/data/ctcae_rules.json` -> `data`.
- Keep writable SQLite database outside `_MEIPASS` per `config_manager.py`.
- Exclude bloat packages (pandas, numpy, scipy, matplotlib, torch, pytest, playwright, boto3, botocore, etc.) to keep binary size under 10 MB (9.78 MB).
- Ensure output executable is located at `dist/HAD Digital.exe` and mirrored to `04_Build/dist/HAD Digital.exe` to support both paths.
- Retain stdlib `email` module in hidden imports as required by `http.server`.

## Artifact Index
- `c:\AI Projects\Kais Project\04_Build\build_exe.py` — Automated build script supporting `--mode {onefile,onedir}`, `--clean`, `--verify`
- `c:\AI Projects\Kais Project\04_Build\HAD Digital.spec` — Single-file PyInstaller spec file
- `c:\AI Projects\Kais Project\dist\HAD Digital.exe` — Standalone executable (9.78 MB)
- `c:\AI Projects\Kais Project\04_Build\dist\HAD Digital.exe` — Mirrored standalone executable (9.78 MB)
- `c:\AI Projects\Kais Project\.agents\worker_m3_1\handoff.md` — Detailed handoff report

## Change Tracker
- **Files modified**:
  - `04_Build/HAD Digital.spec` (created): Single-file PyInstaller specification with asset bundling and bloat exclusions.
  - `04_Build/build_exe.py` (created): Automated packaging, version stamping, binary verification, and test execution script.
  - `dist/HAD Digital.exe` (generated): 9.78 MB standalone Windows executable.
  - `04_Build/dist/HAD Digital.exe` (generated): Mirrored standalone Windows executable.
- **Build status**: PASS (build completed in 5.2s, 9.78 MB < 20 MB)
- **Pending issues**: None

## Quality Status
- **Build/test result**: PASS. `python 05_Test/verify_mvp.py --exe` passed all 8 acceptance criteria steps. `pytest 05_Test` passed 94/94 tests.
- **Lint status**: 0 violations (clean compilation)
- **Tests added/modified**: Standalone executable verification via `05_Test/verify_mvp.py --exe` verified 100%
