P1 Badge Queue every lifecycle publisher

cancel-in-progress: false does not preserve every queued run: a concurrency group permits only one pending run by default, and a newly queued run replaces the existing pending one (GitHub concurrency behavior). Because requested, in_progress, and completed publishers all share this SHA-based group, a fast source run can emit completed while its start publisher is still pending, canceling the publisher before it writes the reset statuses. This is particularly unsafe on reruns, where GitHub does not emit requested: losing the sole in_progress publisher leaves prior successful contexts valid throughout the rerun until completion, allowing required-check evaluation against stale results. Preserve the queued lifecycle events or redesign the group so the reset cannot be replaced.

P2 Badge Finalize statuses for canceled non-Dependabot runs

Restricting this lifecycle finalizer to Dependabot leaves normal pushes, for which status publication is enabled in tests.yml, dependent solely on the shared workflow's per-matrix final steps. After its separate publisher writes pending, canceling the workflow while matrix jobs are queued—or encountering a runner startup failure—means those jobs never execute their final status steps, so the required contexts remain pending indefinitely. GitHub's cancellation process only reevaluates jobs that are already running; add completion handling for non-Dependabot runs or a terminal job that finalizes every context.

🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift

Restrict status writes to the publisher job.

The caller must allow statuses: write, but the referenced reusable workflow currently gives its test job no job-level permissions override. The test job therefore inherits status-write access while it runs the package's test commands. Add explicit read-only permissions to the called test and dependency jobs, and retain statuses: write only for status-publishing jobs. This preserves the caller's permission ceiling without giving test code the publisher's token scope. (docs.github.com)

As per the retrieved least-privilege learning, elevate only the jobs that need a write scope.

statuses: write only on status-publishing jobs. Locate the relevant jobs by
their job identifiers and leave the caller’s permission ceiling unchanged.

Confirmed: the current dev-tools main workflow exposes status-write permission to code-executing jobs. The correction is in dev-tools#362, where all code-executing jobs explicitly deny status writes, all checkouts disable credential persistence, and only the checkout-free metadata publisher has write permission. I corrected the integration order in this PR's description: first config#5/enum#6/framework#10 (existing status ceiling; add Actions-read), then dev-tools#362, then these ten callers. This caller must not merge against the old main implementation. I am leaving this finding open until the shared correction actually reaches main; no CI PR has been merged.

@coisa Thanks for the clarification. This finding remains open until the shared correction reaches main.

The required integration order is:

  1. Merge config#5, enum#6, and framework#10.
  2. Merge dev-tools#362.
  3. Merge the ten caller PRs, including this PR.

This caller must not merge against the old main implementation.

Learning: In php-fast-forward/dev-tools reusable GitHub Actions test workflows, the intended security boundary requires all code-executing jobs to explicitly deny status writes and all checkouts to disable credential persistence. Only the checkout-free metadata publisher may have write permission. Caller workflows must retain the permission ceiling required by that publisher; enforce code-executing job restrictions in the reusable workflow.

P1 Badge Order pending publication before the test matrix

This enables the shared status publisher for every non-Dependabot run, but in the referenced @main workflow the tests matrix and publish_required_statuses both depend only on resolve_php: matrix jobs write final statuses while the independent publisher writes pending for the same contexts. If the publisher's runner is delayed until a fast matrix lane finishes, its later pending becomes the latest status—which GitHub uses for the context—and leaves a successful commit blocked indefinitely. Make the matrix depend on pending publication, or otherwise prevent the pending writer from running after a final writer.
