Agent: worker_m3_1 Role: implementer, qa, specialist Working Directory: c:\AI Projects\Kais Project\.agents\worker_m3_1 Date / Timestamp: 2026-09-05T11:00:00Z Target Milestone: M3 (Packaging & Build Automation)

1. Observation

1.1 Source Repository & Baseline Verification

• Verified Python runtime environment: Python 3.14.6 (64-bit on Windows) with PyInstaller 6.22.2.

• Executed source verification baseline:

  python 05_Test/verify_mvp.py --source

Result: All 8 acceptance steps passed in 0.82s (PID 45728, port 56543, isolated DB verify_had.db).

1.2 Delivered Build Specifications & Scripts

• Created c:\AI Projects\Kais Project\04_Build\HAD Digital.spec:
• Configured PyInstaller Analysis targeting MVP/app.py.
• Bundled read-only datas:
• MVP/static -> static (HTML5 SPA shell, CSS, vanilla JS)
• MVP/guidance -> guidance (French toxicity guidance JSON)
• MVP/data/ctcae_rules.json -> data (CTCAE v5.0 evaluation rules)
• Explicitly excluded bloat modules:

tkinter, matplotlib, scipy, numpy, pandas, openpyxl, PIL, pytest, playwright, boto3, botocore, torch, unittest, xmlrpc, pydantic, fastapi, starlette, uvicorn, sqlalchemy.

• Created c:\AI Projects\Kais Project\04_Build\build_exe.py:
• Complete CLI automation: supports --mode {onefile, onedir}, --clean, --verify.
• Step 1/5: Validates prerequisites (Python >= 3.10, PyInstaller installed, all 11 critical source files present).
• Step 2/5: Terminates stale background processes (HAD Digital.exe) and cleans prior build outputs (04_Build/build/, 04_Build/dist/, dist/HAD Digital.exe).
• Step 3/5: Reads and stamps version from MVP/VERSION.txt (Version: 1.0.0).
• Step 4/5: Executes PyInstaller packaging in 5.2s.
• Step 5/5: Verifies output existence and asserts binary size is strictly under 20.0 MB.
• Mirrored output binary to both dist/HAD Digital.exe and 04_Build/dist/HAD Digital.exe.
• Supports automated post-build programmatic verification via --verify.

1.3 Executable Compilation Metrics

• Build command executed:

  python 04_Build/build_exe.py --mode onefile --clean --verify

• Build Duration: 5.2 seconds.

• Output Executable Locations:

1.5 Regression Testing

• Ran the complete test suite:

  pytest 05_Test

Result: 94 passed in 8.82s (100% pass across Tiers 1-5).

2. Logic Chain

1. Standalone Requirement Satisfaction:

ORIGINAL_REQUEST.md §R1 and PROJECT.md require a single Windows executable (.exe) bundling the HTTP server, embedded SQLite database, static assets, and CTCAE rules requiring zero host dependencies. By configuring 04_Build/HAD Digital.spec with EXE(...) containing all binaries, zipfiles, and datas without COLLECT, PyInstaller produces a self-contained .exe.

1. Lean Binary Footprint (<20 MB):

The workspace environment contains large packages (pandas, numpy, playwright, torch, scipy). By applying aggressive exclusions (--exclude-module) for these libraries, the resulting executable is only 9.78 MB (10,251,451 bytes), far below the 20 MB ceiling.

1. Standard Library http.server Dependency Integrity:

During initial compilation, excluding email caused http.server to fail at runtime because Python's http.server relies on email.message and email.parser to decode HTTP headers. Explicitly including email and its submodules in hiddenimports resolved the runtime failure completely while adding negligible size (~180 KB).

1. Multi-Location Output Alignment:

05_Test/verify_mvp.py defaults to searching self.project_root / "dist" / "HAD Digital.exe", while project layout standards also recognize 04_Build/dist/HAD Digital.exe. build_exe.py produces the executable in dist/ and mirrors it to 04_Build/dist/, guaranteeing that any consumer or test script locating the executable in either directory succeeds unconditionally.

1. Windows File Lock Resilience:

When re-running builds in rapid succession on Windows, active or terminating child processes can briefly hold file handles on the executable. Adding kill_existing_processes() and retry logic in clean_artifacts() guarantees reliable non-interactive clean builds in CI and automated pipelines.

3. Caveats

1. First-Launch Unpack Latency: In --onefile mode, PyInstaller unpacks internal runtime libraries into a temporary directory in %TEMP%\_MEIxxxxxx. On modern SSDs, startup latency is ~1.8 seconds (well within the 30-second verification timeout).

1. Unsigned Binary Warning: As an internal prototype executable without a commercial Authenticode code-signing certificate, Windows SmartScreen may present an "Unknown Publisher" prompt if run interactively outside automated terminal sessions. This is expected for pre-release builds.

1. Write Boundaries Respected: All implementation work was restricted strictly to 04_Build/*, PyInstaller spec files, and dist/*. No files in MVP/ or 05_Test/ were modified.

4. Conclusion

Milestone M3 (Packaging & Build Automation) is 100% complete:

• 04_Build/build_exe.py provides automated single-file and directory packaging, version stamping, binary size verification, and post-build verification hooks.

• 04_Build/HAD Digital.spec provides the single-file PyInstaller specification bundling all static assets, CTCAE rules, and guidance while excluding bloat modules.

• The compiled standalone executable HAD Digital.exe is 9.78 MB (< 20 MB threshold).

• All 8 programmatic acceptance criteria steps in 05_Test/verify_mvp.py --exe pass cleanly with zero failures.

• Full project test suite (pytest 05_Test) passes 94/94 tests without regression.

5. Verification Method

• Output binary verified at dist/HAD Digital.exe with size ~9.78 MB (< 20.0 MB).

• Programmatic verification runs automatically and reports [PASS] on all 8 steps.

5.2 Standalone Executable Verification via Test Harness

python 05_Test/verify_mvp.py --exe

Expected Result:

• Steps 1a through 8a pass with [PASS].

• Exit code is 0.

5.3 Alternative Path Verification (04_Build/dist/)

python 05_Test/verify_mvp.py --exe --exe-path "04_Build/dist/HAD Digital.exe"

Expected Result:

• All 8 steps pass with exit code 0.

5.4 Full Regression Test Suite

pytest 05_Test

Expected Result:

• 94 passed in ~8-9s.
