* feat(docker): schedule image refreshes
* docs(docker): explain weekly image refreshes
* test(scripts): gate workflow-step execution on bash 4 mapfile support
Stock macOS bash 3.2 lacks mapfile; CI truth is Linux bash 5.
* test: cover docker-release suffix threading and sanctioned second caller
* test(codex): wire run-attempt-state into the attempt-extra project
#123345 added the file without a project owner; the full-suite coverage
guard fails for any PR that runs it.
* fix(ci): run build-artifacts PR validation on hosted runners
ci-build-artifacts-testbox.yml pinned PR runs to blacksmith-16vcpu and
ran Testbox lifecycle steps unconditionally, so the prepare-run landing
gate starved for every PR during a Blacksmith outage even with
OPENCLAW_CI_RUNNER_BACKEND=github. PR events now build on ubuntu-24.04
with dispatch-only Testbox steps, mirroring ci-check-testbox.yml.
* test(ci): align build-artifacts dispatch guard
