🔴 Critical: actions/upload-artifact SHA does not match v7.0.1

All 5 upload-artifact pins in this file replace the correct v7.0.1 SHA (043fb46d1a93c77aae656e7c1c64a875d1fc6a0a) with an unverified SHA (b4b15b8c7c6e1ff4146713666d5ba77140d5c8da) while keeping the # v7.0.1 comment.

The official v7.0.1 release confirms commit 043fb46d is the correct pin. The SHA b4b15b8c... does not correspond to any known tagged release.

This is a supply chain integrity regression — the correct SHA from main is being replaced with an unknown one. The change is also unrelated to the pip lock file objective.

Suggested fix: Revert all occurrences back to the original:

⚠️ High: Dead code — AIO version results parsing and upload references non-existent file

This new block parses aio-version-check-results.json and uploads it as an artifact, but scripts/aio-version-checker.py only writes JSON to stdout — it never creates a file with this name. The script was not modified in this PR.

As a result:

  • The jq block always falls to else, reporting issues=0 (false signal)
  • The upload-artifact step finds no file (silent no-op)

This is scope creep beyond the pip lock file objective. Please remove the "Parse results for outputs" block (lines 277–287) and the "Upload AIO version results" step (lines 289–295). If AIO result artifact upload is desired, open a separate PR that also modifies aio-version-checker.py to write output to a file.

⚠️ High: Dead code — same non-existent AIO results file upload

Same issue as security-comprehensive.yml. The "Upload AIO version results" step references aio-version-check-results.json which is never created by aio-version-checker.py. Please remove this step.

### Managing Python Dependencies

This project uses a hash-pinned `requirements.lock` file for reproducible Python dependency installation, satisfying the OSSF Silver Badge `build_repeatable` requirement.

**To update Python dependencies:**

1. Update `requirements.txt` with new or modified dependency versions
2. Run `uv pip compile --generate-hashes requirements.txt -o requirements.lock` to generate the lock file
3. Commit both files: the updated `requirements.txt` and the generated `requirements.lock`

⚠️ High: Incorrect dependency update instructions — source of truth is requirements.in, not requirements.txt

requirements.txt is auto-generated (its header says autogenerated by pip-compile). The human-edited source of truth is requirements.in. The current instructions tell contributors to edit requirements.txt, which will be overwritten on the next compile.

The full dependency chain is:

requirements.in → (pip-compile --generate-hashes) → requirements.txt → (uv pip compile --generate-hashes) → requirements.lock

Suggested fix:

**To update Python dependencies:**

1. Update `requirements.in` with new or modified dependency specifications
2. Run `pip-compile --generate-hashes --output-file=requirements.txt requirements.in` to regenerate the pinned requirements
3. Run `uv pip compile --generate-hashes requirements.txt -o requirements.lock` to regenerate the lock file
4. Commit all three files: `requirements.in`, `requirements.txt`, and `requirements.lock`

4. The lock file ensures CI/CD pipelines and dev containers use exact pinned versions with SHA256 hashes for verified reproducible builds

### HVE Core Integration

Edge-ai uses [hve-core](https://github.com/microsoft/hve-core) for general-purpose prompt engineering artifacts including standardized agents, prompts, and instructions for common development tasks (Bash, C#, Python, task planning, ADR creation, TDD workflows).
