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-all
  actions: 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.

Verified before this PR was opened

0 unparseable workflows · lockfile covers every workflow, no omissions · SPDX on line 1 in every file. The script refuses to push if any of the three fails.

Remediates GitHub Workflow Dependency Locking (public preview), which
rejects runs at startup_failure with zero jobs and no logs. See
hyperpolymath/standards#657.

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.

Proven on hyperpolymath/anamnesis: 6 of 6 workflows dead -> 0
startup_failure, 13 running.

Workflow maintenance

Layer / File(s) Summary
Action reference updates
.github/workflows/abi-verify.yml, .github/workflows/codeql.yml, .github/workflows/coq-build.yml, .github/workflows/ffi-seams.yml, .github/workflows/instant-sync.yml, .github/workflows/push-email-notify.yml, .github/workflows/rust-ci.yml, .github/workflows/status-gate.yml
Selected SHA-pinned actions now use version tags, including actions/checkout, CodeQL, Rust tooling, Swatinem/rust-cache, mlugg/setup-zig, repository-dispatch, and email notification actions.
Reusable workflow updates
.github/workflows/governance.yml, .github/workflows/hypatia-scan.yml, .github/workflows/mirror.yml, .github/workflows/rust-ci.yml, .github/workflows/scorecard.yml, .github/workflows/secret-scanner.yml
Reusable workflow references now use newer commit revisions. Affected workflows add actions: read permissions. Each updated workflow includes an gh actions-lock management comment.

Estimated code review effort: 2 (Simple) | ~10 minutes

Poem

A rabbit checks each workflow line
Tags hop forward, neat and fine
Read permissions join the queue
New pinned revisions pass through
“gh actions-lock,” I softly say
Then nibble YAML hay away
