Full details: Description checkExplanation The description explains the purpose and intended behaviour, but it does not follow the repository template. It omits the required Summary, Changes, RSR Quality Checklist, Testing, and Screenshots sections. It also mentions Rust toolchain changes that are not present in the supplied file summary. Resolution Update the description to use the repository template. Add the required Summary, Changes, RSR Quality Checklist, and Testing sections. Complete the applicable checklist items and add Screenshots or state that they are not applicable. Reconcile or remove the claim about explicit Rust toolchain inputs unless those changes are included in the pull request. Thanks for using CodeRabbit!

Synchronise both dogfood action pins with .github/workflows/actions.lock.
The A2ML and K9 pins differ from their lock records. Restore the recorded SHAs, or, if the current pins are intentional, run gh actions-lock once to regenerate both lock records. Do not edit the lockfile by hand.
The dogfood workflow is listed in the lockfile, so the documented rejection for an unlisted workflow does not apply. This is a minor consistency issue, not an established cause of the validation steps being skipped.

official gh actions-lockfile documentation whether gh actions-lock enforces mismatched GitHub Actions pins at workflow runtime
💡 Result:
<search_synthesis>
GitHub Actions does not natively read or enforce lockfiles (such as actions.lock) at workflow runtime [1][2]. Consequently, if a workflow uses a mutable reference (like a tag or branch) that points to a different commit than what is recorded in a lockfile, the GitHub Actions runner will execute the code currently pointed to by that mutable reference, not the version recorded in the lockfile [1][2]. Tools like gh-actions-lock (the official GitHub-maintained CLI extension) and the community-developed gh-actions-lockfile are designed to provide auditing, verification, and dependency management for GitHub Actions [3][4][1]. These tools operate as part of the CI/CD pipeline—typically during a verification step—to detect mismatches between the workflow's current configuration and the locked state [5][4][1]. If a mismatch is detected, these tools can fail the CI job, but this enforcement is a function of the tool's execution within the workflow, not a native capability of the GitHub Actions platform itself [5][1][2]. To ensure runtime immutability, it is recommended to pin actions directly in the workflow YAML using full 40-character commit SHAs [1][2]. The lockfile serves as a record for managing these dependencies and detecting drift, rather than as a runtime enforcement mechanism [1][2].

site:github.com/github/gh-actions-lock README onboarded workflows enforce locked commit runtime actions.lock verification mismatch exact semantics
💡 Result:
<search_synthesis>
gh-actions-lock is a GitHub CLI extension designed to enhance the security of GitHub Actions by pinning workflow dependencies to verified commits [1]. Key aspects of its operation include: Onboarding and Enforcement: Workflows are onboarded to a lockfile (located at.github/workflows/actions.lock) on a per-workflow basis [1]. Once a workflow is onboarded, the system enforces that all dependencies are present in the lockfile [1]. This ensures that the specific commit recorded in the lockfile is the exact code executed on the runner [1]. Verification and Semantics: The tool provides mechanisms to verify the integrity of the lockfile and prevent tampering [1]. Specifically: - Forgery Protection: Lockfiles are verified for forgeries [1]. - Commit Verification: The tool ensures that the recorded SHA exists within the expected references [1]. - Identity and Mismatch Handling: Repository identity is recorded, and the system blocks execution at runtime if there are redirects or mismatches between the expected and actual dependency identity [1]. Maintenance: - Standard runs (gh actions-lock) pin resolvable actions to a SHA and update the lockfile [1]. - Pins to branches or partial versions (e.g., main, v4) are trusted from the lockfile and are not re-resolved unless the --relock flag is used [1]. - The tool handles cases where recorded commits are no longer reachable upstream, requiring the --accept-moved flag to re-resolve them [1]. - A full-directory run prunes lockfile entries for workflows that have been deleted, while scoped runs do not prune out-of-scope entries [1].

Regenerate the SMTP action lock and annotation.
When PUSH_EMAIL_ENABLED is true, this job reaches the SMTP action. The workflow pins 22e7bdb322c430c1d0dac6b3bb307f4bb139d0be (v0.3.0), but the onboarded lock entry records v0.2.0 at ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7. The lock contract requires the recorded commit to be the commit executed by the workflow, so this mismatch can cause the workflow to be rejected before the notification step. Run gh actions-lock and update the annotation to v0.3.0 and 22e7bdb322c430c1d0dac6b3bb307f4bb139d0be.

…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.
