chore(ci): SPDX headers on line 1 and Actions lockfile minted - #93
Merged
Conversation
Two estate gates, one change. **SPDX.** `governance / Workflow security linter` checks `head -1 | grep`, so a workflow carrying its identifier below a managed-by comment reports as missing one. Each file's OWN identifier is moved to line 1 — nothing is imposed, because repositories here are variously MPL-2.0, PMPL-1.0-or-later and AGPL-3.0-or-later and a default would mis-declare the minority. Licences seen here: MPL-2.0. **Lockfile.** `gh actions-lock` resolves each symbolic ref to a verified commit plus owner_id, repo_id and the transitive dependencies of composite actions — which is what OSSF Scorecard's Pinned-Dependencies check is asking for, and what an inline SHA cannot express. ⚠ Do NOT additionally SHA-pin inline. The mechanisms are mutually exclusive: `gh actions-lock` refuses a ref no tag or branch contains, so inline pinning REMOVES actions from the lockfile. Measured on hypatia 2026-08-07 — 40 inline pins caused 14 startup_failures and dropped 7 lockfile entries. Verified: all workflows parse, no duplicate identifiers, lockfile verify says "All 16 workflows have complete lockfile coverage.".

`gh actions-lock` inserts `# This workflow is managed by gh actions-lock.` at line 1, which displaced the SPDX identifier moved there earlier in this branch. The linter greps `head -1` only, so the header read as missing again. Each file's OWN identifier is moved back to line 1 — nothing imposed. Files already correct are untouched, and any file carrying two identifiers aborts the change rather than guessing.
