actions/checkout v7.0.0 (2026-06-18) is internally an ESM rebuild plus
one behavioral change: it blocks checking out a fork PR head ref under
pull_request_target / workflow_run (PR #2454). No Sea Haven workflow uses
those triggers, so there is no reachable behavior change. The Node 24
runtime requirement already landed at v6, so v6 -> v7 carries no new
runner requirement. All runners here are GitHub-hosted (ubuntu, macos).
Covers all 16 checkout pins across 12 reusable/standalone workflows plus
the dependency-review workflow-template scaffold. Consumers on @main pick
this up automatically on merge.
Add callable-labeler.yaml, a reusable workflow that carries the label
rules inline as the single source of truth and writes them to the runner
at execution time, so caller repos need only a short caller workflow and
no per-repo labeler.yml. Triggered by callers on pull_request (private org
takes no fork PRs); requires contents:read + pull-requests:write +
issues:write on every caller so labeler@v5 can create missing labels.
Remove the workflow-templates/labeler.yml starter it supersedes (no
ruleset workflows-rule or compliance-audit reference depends on it).
Add the repo's own dependabot.yml (github-actions, weekly, grouped
minor+patch) to keep the action pins current per the Pinning Principle.
