📝 SummarySummary by CodeRabbit
WalkthroughThe pull request replaces mutable GitHub Actions version tags with immutable commit SHA references across 17 workflows. Workflow logic remains unchanged, except for an explicit Rust toolchain input. ChangesWorkflow action pinning
Priority: ➖ Normal Estimated code review effort: 2 (Simple) | ~10 minutes Change: Bug fix Suggested reviewers: Merge Risk: 🟡 Moderate · up to The pinning change is mostly safe, but one workflow now declares the Rust toolchain twice in the same step, which can stop that workflow from running at all. The generated pin-record file is also out of date with one of the new pins. Both are small edits that should be made before merging; nothing here affects the shipped product. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

The listed workflows run on pull_request events and check out the pull-request tree. Subsequent steps execute commands or process that tree. actions/checkout persists GITHUB_TOKEN in local Git configuration by default, so pull-request-controlled code can read the token.

Regenerate .github/workflows/actions.lock after the CodeQL update. The lockfile records github/codeql-action@v4.37.9 and commit cdf488f595d80d6e07e03d4674febd5ab45fa938, while both workflows use the valid v4.38.0 commit b96794f015dfd88f77b49b1c93e0fa7110f94c63. The workflow linter and SHA hook do not compare exact pins with the lockfile, so this does not currently fail CI. It leaves the generated pin-authority record inaccurate.
Run gh actions-lock to update the lockfile.

…0.1.6) `actions.lock` is authoritative: the workflows carry readable refs and the lock records the commit each ref resolves to, which is what actually runs. Refs that stop matching the manifest make the whole repository unstartable — `startup_failure`, "Invalid lockfile". Regenerated with the official extension (`github/gh-actions-lock`). The hand-pinned SHA refs are reverted to their readable form here precisely because the lockfile, not the workflow, is what pins them.

fix(ci): pin third-party actions to full commit SHAs
The account's Actions policy requires a full-length SHA ref. A tag or branch ref is refused at
startup —
startup_failure, no jobs, "this workflow graph cannot be shown" — so these workflowscould not run at all. This resolves each ref to the commit it currently points at and records the
ref in a trailing comment, e.g.
actions/checkout@<sha> # v4.dtolnay/rust-toolchaintakes its toolchain from the ref itself, so those steps also gained anexplicit
with: toolchain:input; without it, a SHA ref would silently lose the channel.No behaviour is intended to change beyond the pins.
