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 workflows
could 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-toolchain takes its toolchain from the ref itself, so those steps also gained an
explicit with: toolchain: input; without it, a SHA ref would silently lose the channel.

No behaviour is intended to change beyond the pins.

official gh actions-lockfile documentation exact workflow synchronization and validation semantics

💡 Result:

<search_synthesis>
The term "actions-lockfile" refers to two distinct but related concepts in the GitHub Actions ecosystem: the official, shared lockfile format maintained by GitHub, and third-party tooling (such as gh-actions-lockfile or gh-actions-lock) that implements this format to provide dependency pinning and verification [1][2][3]. Official Lockfile Format The official actions-lockfile project provides the authoritative definition of the dependency lockfile format [1][4]. It is designed as infrastructure for tooling to record and verify resolved dependency pins, rather than a tool that performs resolution or vulnerability scanning itself [1][4]. Key semantics include: - Format: A YAML document located at .github/workflows/actions.lock [1][4]. - Schema: The format is defined by a JSON Schema (currently v0.0.2) [1][4]. - Structure: It contains three top-level keys, including workflows (a flat list of transitive dependencies per workflow) and dependencies (a deduplicated graph of entries) [1][4]. - Purpose: It enables tools to audit and verify that the exact action pins (commit SHAs) in use across a repository&#39;s workflows match the recorded state, mitigating risks like tag hijacking [1][3]. Third-Party Tooling Semantics Tools like gh-actions-lockfile and gh-actions-lock implement this format to provide workflow synchronization and validation [2][3]. Their semantics generally follow these patterns: 1. Generation: The tool scans workflows, resolves all actions (including transitive dependencies) to their exact commit SHAs, and generates the actions.lock file [2][3]. 2. Verification: During CI, the tool compares the current workflow dependencies against the lockfile [2][5]. If a mismatch is detected—such as a tag being re-pointed to a different commit—the verification fails (typically exiting with a non-zero status) [2][3][5]. 3. Integrity: Advanced implementations include Subresource Integrity (SRI) hashes (SHA-256) to ensure the content of the fetched action has not been modified [2][6][5]. 4. Security: These tools protect against supply chain attacks by ensuring that what is executed on the runner is exactly what was previously audited and locked, blocking redirects or mismatches at runtime [3][5]. In summary, the official project provides the schema and parser infrastructure [1][4], while third-party tools provide the operational logic to synchronize workflow definitions with the lockfile and validate them during execution [2][3].

The lockfile records the resolved transitive dependency graph for a repository&`#39`;s workflows so tools can audit and verify the exact action pins in use. ## Background This project provides the shared, authoritative lockfile format that GitHub Actions tooling uses to record and verify resolved dependency pins. It is part of GitHub&`#39`;s broader Workflow Dependency Pinning effort, and the schema and parser will continue to evolve toward a stable `v1.0.0`. Contributions are welcome — see CONTRIBUTING.md. ## Installation ```sh go get github.com/github/actions-lockfile/go/pkg/lockfile ``` The Go module lives under `go/` so the repository can grow additional language bindings around the same lockfile schema. ## Usage ### Parse a lockfile and look up a workflow&`#39`;s pins ```go package main import ( "fmt" "os" lockfile "github.com/github/actions-lockfile/go/pkg/lockfile" ) func main() { contents, err := os.ReadFile(lockfile.Path) // ".github/workflows/actions.lock" if err != nil { panic(err) } file, err := lockfile.Parse(contents) if err != nil { panic(err) } pins, ok := file.LookupWorkflow(".github/workflows/release.yml") if !ok { fmt.Println("workflow not present in lockfile") return } for _, key := range pins { fmt.Println(key) // e.g. actions/checkout@v6.0.2 } } ``` ### Surface structured parse errors `Parse` returns a `*lockfile.ParseError` carrying line and column for semantic failures, so callers can anchor diagnostics on the lockfile itself instead of scraping yaml.v3&`#39`;s error string. ```go file, err := lockfile.Parse(contents) if err != nil { var perr *lockfile.ParseError if errors.As(err, &perr) { fmt.Printf("%s:%d:%d: %s\n", lockfile.Path, perr.Line, perr.Column, perr.Msg) return } panic(err) } _ = file ``` ## Schema The lockfile is a YAML document whose shape is defined by a JSON Schema 2020-12 document embedded in the package and reachable via `lockfile.Schema()`. The current schema version is `v0.0.2` (`schema/lockfile-v0.0.2.json`). The on-disk file lives at `Path` (`.github/workflows/actions.lock`) and has three top-level keys: ```yaml version: v0.0.2 workflows: # workflow path -> flat, transitive list of pin keys .github/workflows/release.yml: - actions/checkout@v6.0.2 dependencies: # pin key -> resolved action metadata actions/checkout@v6.0.2: ref: v6.0.2 commit: sha1-de0fac2e... owner_id: 44036562 repo_id: 197814629 ``` A pin key is `OWNER/REPO@REF`. The same key appears in both `workflows` (as flat transitive lists) and `dependencies` (as deduplicated graph entries with `uses:` links to direct dependencies). The parser also reads v0.0.1 lockfiles (which used `tag`/`branch` fields and `:algo-hex` suffixed pin keys) and normalizes them to the v0.0.2 `File` struct. Use `ParseWithPolicy` with a `VersionPolicy` to control which versions are accepted. ## Compatibility and stability - The Go module follows semver.

For unexpected changes, review the upstream action&`#39`;s commit history before regenerating the lockfile. ... ### SHA Verification ...

To skip integrity checking (e.g., for faster CI runs), use `--skip-integrity`: ... ### SHA-Only Mode ...

The > lockfile format, command flags, and behavior may change without notice between > releases. Use it, file issues, and expect rough edges. ## Background gh-actions-lock is part of GitHub&`#39`;s Workflow Dependency Pinning effort. It gives repositories a lockfile that pins every workflow dependency to a verified commit, so what runs on the runner is exactly what you locked. Development is ongoing and behavior may still change. Contributions are welcome. See CONTRIBUTING.md to get started. ## Requirements Requires the `gh` CLI. Install it first, then install the extension: ```bash gh extension install github/gh-actions-lock ``` ## Usage Scan every workflow under `.github/workflows/` directory, pin each resolvable action to a SHA, and update the lockfile: ```bash gh actions-lock ``` After the initial run to onboard workflows, you will need to run `gh actions-lock` when: - A new workflow is created that has `uses` dependencies. - An existing workflow adds or removes `uses` dependencies. A full-directory run (`gh actions-lock` with no path arguments) also prunes lockfile entries for workflows that have been deleted from `.github/workflows/`, dropping any dependencies left orphaned by the removal. Scoped runs that name specific workflows never prune out-of-scope entries. Pins to branches or partial versions (e.g. `main`, `v4`) are trusted from the lockfile and not re-resolved on a normal run. To bump them to the current upstream commit, run: ```bash gh actions-lock --relock ``` `--relock` re-resolves refs that have legitimately moved and rewrites the lockfile to the new SHA. Suspicious pins whose recorded commit is no longer reachable upstream are left as errors — use `--accept-moved` to re-resolve those as well. ### Self repository actions (`$/…`) `uses: $/…` references an action or reusable workflow in the **same repository** as the defining file, resolved at the **running commit**. Because it always resolves to that repository&amp;`#39`;s running SHA it is **inherently pinned** — no lockfile entry is required, and it is valid anywhere a relative `./…` reference is: ```yaml steps: - uses: $/actions/my-action # same-repo action, inherently pinned jobs: call: uses: $/.github/workflows/reusable.yml # same-repo reusable workflow ``` A trailing `@ref` (e.g. `$/actions/my-action@v1`) is rejected — the ref is always the running commit. Same-repo `./…` composite action references are automatically converted to `$/…` on fix runs. This rewrites `./…` steps both in your workflows and in your in-repo composite action definitions (`action.yml`). Only `./…` paths that resolve to an in-repo action file are rewritten. To leave `./…` refs untouched, opt out with `--no-migrate-local-actions`: ```bash gh actions-lock --no-migrate-local-actions ``` ## How it works A repo gets a lockfile (located at `.github/workflows/actions.lock`) and workflows are onboarded to the lockfile on a per-workflow basis. Workflows that are onboarded to the lockfile enforce that all dependencies are present in the lockfile and guarantees that the locked commit for an Action is what&`#39`;s executed on the runner. Lockfiles are also verified for forgeries. The sha must exist in the refs it&`#39`;s stated to exist in.

If verification fails, the lockfile is automatically regenerated and committed to the PR: ... ``` name: Verify Actions # change this to whichever events matter to you on: [pull_request] ... permissions: pull-requests: write ... jobs: verify-actions: runs-on: ubuntu-latest steps: - uses: actions/checkout@v6 - uses: gjtorikian/gh-actions-lockfile@v1 with: mode: verify ... update-lockfile: needs: verify-actions if: failure() runs-on: ubuntu-latest permissions: # Gives the default GITHUB_TOKEN write permission to commit and push the # added or changed files to the repository. contents: write steps: - uses: actions/checkout@v6 with: ref: ${{ github.head_ref }} - uses: gjtorikian/gh-actions-lockfile@v1 with: mode: generate - uses: stefanzweifel/git-auto-commit-action@v7 with: commit_message: "Update actions lockfile" file_pattern: ".github/actions.lock.json" ... When you update an action version (e.g.,`actions/checkout@v4` to`@v5`), or if the action ref changes outside of your control, the verify job will fail, triggering the update job to regenerate and commit the lockfile to your PR automatically. ... both the workflow and lockfile ... ### When Verification Fails Unexpectedly ... If`verify` fails, but you didn&`#39`;t change any actions, investigate: ... - New dependency detected: A composite action you use added a new transitive dependency - SHA mismatch: An upstream maintainer force-pushed or retagged a version (this is a potential supply chain concern) - Integrity mismatch: The tarball content has changed for the same SHA (rare, but a serious supply chain concern) - Missing action: An action was removed from your workflow but is still in the lockfile ... unexpected changes, ... upstream action&`#39`;s ... the lockfile ... When you run`verify`, the tool checks that all locked action refs still resolve to the same commit SHAs. This detects if an upstream maintainer has re-pointed a tag to a different commit (a supply chain concern known as "tag hijacking"). ... ### Integrity Verification ... The`verify` command also: ... 1. Re-downloads each action&`#39`;s tarball from GitHub 2. Computes the SHA256 hash of the tarball 3. Compares it against the stored`integrity` hash in your lockfile ... If any hash mismatches, verification fails. This detects if an action&`#39`;s content has been modified after your lockfile was generated—even if the commit SHA hasn&`#39`;t changed. ... skip integrity checking ... e.g., ... ), use`--skip-integrity ... the`verify ... command checks your locked ... for known vulnerabilities. ... ### SHA-Only Mode ... For maximum security, you can enforce that all action references in your workflows use full 40-character commit SHAs instead of tags or branches: ... ``` gh-actions-lockfile generate --require-sha ... This fails if any workflow uses a tag like`@v4` instead of a full SHA like`@b4ffde65f46336ab88eb53be808477a3936bae11`. ... ### GitHub Action (recommended) ... Add this action to your workflow to verify the lockfile: ... ``` - uses: gjtorikian/gh-actions-lockfile@v1 with: mode: verify # or &`#39`;generate&`#39`; ... Action inputs: ... | Input | Description | Default | | --- | --- | --- | | `mode` | Mode to run in:`generate` or`verify` | `verify` | | `token` | GitHub token for API access | `${{ github.token }}` | | `workflows` | Path to workflows directory | `.github/workflows` | | `output` | Path to lockfile | `.github/actions.lock.json` | | `comment` | Post a PR comment when verification fails (verify mode only) | `true` | | `require-sha` …[truncated]
