ci: add actionlint - #63

A duplicate env: key in a sibling repo's release.yml made GitHub refuse to load the workflow. It surfaced as a "workflow file issue" on unrelated pushes, the release event ran nothing, and a version sat unpublished for hours. yaml.safe_load keeps the last value for a duplicate key without complaining, so local validation passed. actionlint reports it directly. Fetched by pinned version and checksum-verified rather than run as a third-party action, so a check that exists to guard the workflow supply chain does not add to it. Runs only when .github/workflows changes, and this repo is clean against it today. No test-environment guard here: this repo tests against third-party distributions on purpose, so there is no package of its own to shadow.

env:key in a sibling repo'srelease.ymlmade GitHub Actions refuse to load the workflow. It surfaced as a "workflow file issue" on unrelated pushes, the release event ran nothing, and a version sat unpublished for hours.It got through because
yaml.safe_loadkeeps the last value for a duplicate key without complaining. actionlint says it plainly:Verified against a reproduction of the exact broken file before adding it.
On how it's installed: fetched by pinned version with a checksum verification, not run as a third-party action. actionlint publishes no official action, and a check whose purpose is guarding the workflow supply chain should not add a new dependency to it.
Triggered only on changes under
.github/workflows, so it costs nothing on ordinary PRs. This repo is clean against it today, so it adds no backlog.The sibling PRs also carry a pytest guard against a suite silently grading an installed wheel instead of the tree. This repo tests against third-party distributions on purpose and has no package of its own to shadow, so it gets actionlint only.
