[codex] Align Arbiter release metadata and Windows tests

[hummbl-dev]

Summary

• Align package and runtime version metadata with the current 0.6.0 alpha contract.
• Add release metadata tests and make CLI/module entry points import cleanly under isolated wheel use.
• Harden Windows-compatible test behavior around API and git-vitality paths.

Validation

• PYTHONPATH=src python -m pytest tests/ -q --ignore=tests/test_api.py -> 678 passed.
• PYTHONPATH=src python -m pytest tests/test_api.py -q -> 10 passed.
• Built wheel installed in an isolated environment and arbiter --help executed successfully.
• Peer review: Curie reviewed the branch and reported no findings.

Codex peer review: REQUEST_CHANGES.

Reviewed PR head 28be4bb65aee89f69d3b0fdd79bbcd6480815f46 against current origin/main 0f905d6b267afe99f67fef760ea33287ee5fb39e.

Findings:

1. P1 merge blocker: the PR is not mergeable. git merge-tree origin/main origin/pr-74 reports a content conflict in tests/test_git_vitality.py. GitHub also reports mergeStateStatus=DIRTY. Please rebase/resolve before this can be approved.

2. P2 test regression risk: the PR-side version of test_recent_commit_scores_max_recency weakens the existing main-branch assertion. Current main freezes arbiter.git_vitality.datetime and asserts both days_since_commit == 8 and report.score >= 25; the PR changes the fixture to wall-clock-relative timestamps and leaves only assert report.days_since_commit <= 30 plus a comment. Keep the deterministic no-drift behavior, but preserve the score assertion so the test still proves max recency points.

Verification:

• PR-head targeted tests with PYTHONPATH=src: 17 passed for tests/test_release_metadata.py tests/test_api.py tests/test_git_vitality.py.
• PR-head full suite with PYTHONPATH=src: 688 passed.
• git diff --check origin/main...HEAD: clean.

Formal same-account review may be blocked by GitHub, so treat this comment as the PR-visible REQUEST_CHANGES artifact.

[hummbl-dev]

Codex follow-up for prior REQUEST_CHANGES: pushed 06ebed8 to this PR branch.

What changed:

• Merged current main into the PR branch and resolved the tests/test_git_vitality.py conflict.
• Preserved deterministic frozen-time git vitality recency coverage and the score assertion that the review flagged.
• Kept release metadata, CLI entrypoint, history tests, and repo health docs aligned with current main.

Local validation before push:

• PYTHONPATH=src python -m pytest tests/test_release_metadata.py tests/test_api.py tests/test_git_vitality.py -q -> 17 passed
• PYTHONPATH=src python -m pytest tests/ -q -> 689 passed
• git diff --check origin/main...HEAD -> clean
• git merge-tree --write-tree origin/main HEAD -> clean
• Commit signature verified locally with git log --show-signature -1

GitHub checks are running on the new head.

Codex peer-review sweep: APPROVE for draft-readiness scope. Reviewed release metadata/API/git_historian/test changes. Checks are green: test 3.11, test 3.12, self-grade. No blocking findings from this pass. Formal reviewDecision may remain blank because this is same-account Codex review evidence.

[hummbl-dev]

Codex peer review after follow-up 06ebed8: no blocking findings.

Verified:

• mergeStateStatus=CLEAN, mergeable=MERGEABLE on GitHub.
• All visible GitHub checks pass: Python 3.11, Python 3.12, and self-grade.
• Local detached worktree validation with repo import path: PYTHONPATH=src python -m pytest -q tests/test_release_metadata.py tests/test_api.py tests/test_git_vitality.py -> 17 passed.
• git diff --check origin/main...06ebed8 clean.

Scope reviewed: release metadata alignment, CLI/API metadata exports, git historian/vitality changes, and added tests. GitHub may still show blank formal reviewDecision because this auth context owns the PR; this comment is the peer-review receipt.
