check / check (push) Canceled after 0s
The canonical check workflow gave its job no time limit, so a hung script/cibuild held the shared runner until the runner's own default. The check job now sets timeout-minutes: 20. script/cibuild runs three Docker builds (the test phase, the lint phase, then the image, which runs both again), each held to the 5-minute build limit, plus the bootstrap. REPO_POLICIES.md and both checklists name the limit among what the workflow sets. Model: opus-5-5
