Remediates GitHub Workflow Dependency Locking (public preview, no changelog entry), which rejects runs at startup_failure — zero jobs, no logs, nothing in REST or GraphQL. Full analysis: hyperpolymath/standards#657.
Proven on hyperpolymath/anamnesis: 6 of 6 workflows dead → 0 startup_failure, 13 running.
Five steps, in order — each blocks the next
1. Unbreak the workflow YAML. Any permissions: carrying a scalar with an indented mapping under it:
permissions: read-allactions: read # <- mapping under a scalar. Unparseable.
This reaches past the one file: gh actions-lock refuses to run when any workflow in the repo fails to parse, so the repo can never acquire a lockfile and can never self-heal.
2. Repin standards reusables off commits with no actions.lock. The rejection requires the callee to be covered at the pinned SHA — unsatisfiable at a pre-lockfile commit.
3. Generate the lockfile with gh actions-lock.
4. Hand-add the reusable-caller entries the tool omits, as '<path>': [].
⚠️ Measured across 218 repos: P(startup_failure | has lockfile) = 91.7% vs 15.8% without — because every workflow a lockfile omits is rejected. A partial lock is worse than none. Running gh actions-lock and stopping there is how this outage spread.
5. Restore SPDX-License-Identifier to line 1, which the tool displaces with its own banner and which the workflow-security linter greps via head -1.

Five steps, in order, because each blocks the next:
1. Unbroke any workflow whose `permissions:` carried a scalar with an
indented mapping under it - blind-permissions-insertion damage. This
matters beyond the one file: gh actions-lock refuses to run when ANY
workflow in the repo fails to parse, so the repo could never acquire a
lockfile and could never self-heal.
2. Repinned hyperpolymath/standards reusables off commits that have no
actions.lock. The rejection requires the CALLEE to be covered at the
pinned SHA, which is unsatisfiable at a pre-lockfile commit.
3. Generated the lockfile with gh actions-lock.
4. Hand-added the reusable-workflow caller entries the tool omits, as
'<path>': []. Measured across 218 repos: P(startup_failure | has
lockfile) = 91.7% vs 15.8% without, because every workflow a lockfile
OMITS is rejected. A PARTIAL lock is worse than none - running
gh actions-lock and stopping there is how this outage spread.
5. Restored SPDX-License-Identifier to line 1, which the tool displaces
with its own banner and which the workflow-security linter greps with
head -1.
Verified before push: 0 unparseable workflows, lockfile covers every
workflow with no omissions, SPDX on line 1 in every file.

Pull Request Overview
This review identifies critical gaps in the implementation of the GitHub Workflow Dependency Locking strategy. While the PR description claims to add a complete 'actions.lock' and fix YAML syntax errors, the lockfile is missing from the provided diff, making verification impossible. Additionally, Codacy analysis indicates the changes are not currently up to standards due to new security issues.
A significant security regression was observed: several third-party actions were moved from commit SHAs to mutable version tags. This introduces supply-chain risks that the 'actions.lock' is intended to mitigate, but standard hardening requires pinning SHAs directly in the workflow files. Furthermore, the remediation tool used has introduced redundant banner comments across multiple files.
About this PR
The 'actions.lock' file is not present in the diff. This is required to verify the PR's core functionality and ensure all workflow dependencies, including manually added caller paths, are correctly locked.
The remediation tool (Claude Code) has introduced duplicate banner comments (# This workflow is managed by gh actions-lock.) on line 3 of most workflows where the header already existed on line 2. These should be cleaned up globally.
Test suggestions
Verify all workflows pass a YAML syntax check (gh actions-lock requires this).
Verify SPDX-License-Identifier is on line 1 across all workflow files.
Verify that all GitHub Actions are pinned to specific versions/tags compatible with the lockfile.
Missing recommended test scenario: Verify the completeness of actions.lock by checking for manual inclusions of caller paths.

Low confidence findings
The PR description mentions fixing 'indented mapping under a scalar' errors, but the provided diffs do not show this specific remediation. Please ensure the intended syntax fixes are included in the commit.

🔴 HIGH RISK
Pin this third-party action to a full-length commit SHA for security. Using a mutable tag like 'v2.2.1' introduces a supply-chain risk.
Try running the following prompt in your IDE agent:
Find the full commit SHA for 'goto-bus-stop/setup-zig@v2.2.1' and update the 'uses' field to use that SHA instead of the tag, appending the tag as a comment (e.g., uses: goto-bus-stop/setup-zig@ # v2.2.1).

⚪ LOW RISK
Nitpick: Duplicate banner comment introduced; line 2 already states the workflow is managed by gh actions-lock. You should remove this redundant line.
