# Phase 13 Plan 02: Release Workflow Summary

**PyPI release workflow with OIDC trusted publishing, triggered by v* tags**

## Performance

- **Duration:** 2 min
- **Started:** 2026-01-19T03:45:00Z
- **Completed:** 2026-01-19T03:47:00Z
- **Tasks:** 3
- **Files modified:** 1

## Accomplishments
- Release workflow triggered on v* tags (v1.0.0, v2.0.0-beta, etc.)
- Build job creates wheel and sdist using `python -m build`
- Publish job uses OIDC trusted publishing (no API tokens needed)
- PyPI trusted publisher configured by user

## Task Commits

Each task was committed atomically:

1. **Task 1: Create release workflow with build job** - `8928856` (feat)
2. **Task 2: Add publish job with trusted publishing** - `3e8e60b` (feat)
3. **Task 3: Checkpoint for PyPI trusted publisher** - User confirmed configuration

**Plan metadata:** `cc7649b` (docs: complete plan)

## Files Created/Modified
- `.github/workflows/release.yml` - Release workflow with build and publish jobs

## Decisions Made
- **CI-02-OIDC:** Use OIDC trusted publishing instead of API tokens for better security (no secrets to manage or rotate)
- **CI-02-ENV:** Use 'pypi' environment name as the standard convention for PyPI trusted publisher configuration

## Deviations from Plan
None - plan executed exactly as written.

## Issues Encountered
None.

## User Setup Required

**External service configuration was required.** User completed:
- PyPI trusted publisher configuration for OIDC authentication
- GitHub environment 'pypi' created in repository settings

## Next Phase Readiness
- CI/CD phase complete with test and release workflows
- Package can be published to PyPI by pushing a version tag
- Ready to proceed to Phase 14 (Documentation)
