## Status
Milestone M3: Packaging & Build Automation successfully completed.

## Steps
- [x] Step 1: Read ORIGINAL_REQUEST.md, PROJECT.md, DISPATCH.md, proposed_build.py, and proposed_HAD_Digital_onefile.spec.
- [x] Step 2: Initialize BRIEFING.md and progress.md.
- [x] Step 3: Run baseline source verification `python 05_Test/verify_mvp.py --source` to verify server functionality.
- [x] Step 4: Implement `04_Build/HAD Digital.spec` (single-file mode, bundling assets, bloat exclusions).
- [x] Step 5: Implement `04_Build/build_exe.py` (CLI interface supporting `--mode`, `--clean`, `--verify`, building `HAD Digital.exe`).
- [x] Step 6: Execute automated build `python 04_Build/build_exe.py --mode onefile --clean`.
- [x] Step 7: Verify output binary exists in `dist/` and check file size (<20 MB; actual 9.78 MB).
- [x] Step 8: Run programmatic verification against compiled `.exe` using `python 05_Test/verify_mvp.py --exe` (all 8 acceptance criteria passed).
- [x] Step 9: Run pytest test suite in `05_Test/` to verify no regressions (94/94 passed).
- [x] Step 10: Complete `handoff.md` and send completion message to parent.
