ci: SHA-pin third-party GitHub Actions#10
Merged
Conversation
Pin third-party actions to immutable commit SHAs (version in trailing comment) to close the mutable-tag supply-chain vector exploited by the tj-actions and May 2026 Mini-Shai-Hulud cache-poison campaigns. GitHub-maintained actions/* and github/* left on tags (out of scope). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

SHA-pin third-party GitHub Actions
Pins 8 third-party action reference(s) in this repo to immutable commit SHAs.
Scope: Only genuinely third-party actions (owner not
actions/github) that were on mutable refs (tags/branches) were pinned. GitHub-maintainedactions/*andgithub/*actions, actions already pinned to a 40-char SHA, and local./...actions/reusable-workflow calls were intentionally left unchanged. Each pinned line keeps a# <version>trailing comment so the intended version stays readable to humans and Dependabot. Pins point at the commit each tag resolved to at audit time (2026-06-07).No unresolved refs.
