fix: --write-baseline refuses a dev-source stack#5
Merged
Conversation
…stack Nightly releases are wheels/tags-only: source main never gets a version-bump commit, so a source-checkout/PYTHONPATH/editable stack reports the last-committed version string (currently 2026.7.6.649) while PyPI moves on. A baseline snapshotted from one silently pins a version the release train has passed — the exact incident the wiki-currency CI caught on PR #3. write_baseline() now inspects the install kind and refuses dev stacks with a message naming the clean-venv procedure (env -u PYTHONPATH matters: an ambient PYTHONPATH aliases even a fresh venv back to local source); --allow-dev-stack overrides deliberately. Regression test added; the skill documents the guard. Verified live: dev stack refused, release-wheel venv writes a byte-identical baseline. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Closes the recurrence path of the PR #3 CI catch: nightly releases are wheels/tags-only, so dev-source stacks permanently report the last-committed version (
2026.7.6.649today) while PyPI moves on.--write-baselinenow refuses such a stack (override:--allow-dev-stack), with the clean-venv procedure in the error message and the skill doc. Regression test added (suite 53/53); verified live in both directions — the release-wheel venv writes a byte-identical baseline.The permanent automation half is the already-filed PyAutoBuild wiring prompt (baseline regenerated from the release wheel at each release, as autolens_assistant gets today).
