Release flow

feature branch  →  PR  →  CI gate (lint + test) must pass
                           merge blocked until green
                               ↓
                           merge to main (rebase)
                               ↓
                           versioning.yml fires on push to main:
                           → cz bump → tag vX.Y.Z → dispatch release.yml
                               ↓
                           release.yml (on tag / dispatch):
                           → GitHub release (wheel + sdist attached)
                           → PyPI via OIDC trusted publishing (no stored token)
                           → Zenodo webhook (if enabled)

PyPI setup (one-time per repo)

Uses OIDC trusted publishing — no API token stored in GitHub secrets.

1. pypi.org → project → Settings → Publishing → Add trusted publisher
2. Owner: <github-user>, Repository: <repo>, Workflow: release.yml
3. Done — the workflow handles authentication automatically.

Branch protection (required for CI gate)

Repo settings → Branches → Add rule for main:

• ✅ Require status checks: CI job
• ✅ Require branches to be up to date
• ✅ Require linear history

For the auto-bump workflow to push the bump commit back to main:

• ✅ Allow specified actors to bypass → add github-actions[bot]

Docs

uv run mkdocs serve

Deploy to GitHub Pages on push to main via docs.yml (automatic).
