name: Test release (TestPyPI)

# Manual dry-run of the release packaging path: build the same cibuildwheel
# matrix + sdist as the real release, then publish to TestPyPI. Unlike
# release.yml it has NO side effects — no version bump, no commit/tag, no GitHub
# Release — so it is safe to run repeatedly to verify the build + upload path.
#
# Publishes via TestPyPI Trusted Publishing (OIDC) by default — configure a
# trusted publisher on test.pypi.org for this repo + this workflow filename
# (https://docs.pypi.org/trusted-publishers/). If the TESTPYPI_API_TOKEN secret is
# set instead, the publish action uses that token. Uploads the version currently in
# pyproject.toml with `skip-existing`, so re-runs of the same version are no-ops.

  # Build the same wheels matrix + sdist as the real release, via the shared
  # reusable workflow. No release-meta overlay: the dry-run packages the version
  # currently in pyproject.toml. Uploads `wheels-<os>` + `sdist` for publish.
