CI's Linux check job runs within about two minutes of its 30-minute timeout, so a branch that adds tests can be cancelled with no test failing. On 2026-10-27 the two successful Linux check jobs before 07:00Z took 28 minutes each, their race stage over internal/ about 25 of them. Pull request #1147's job was cancelled at 30m16s while its race stage was still printing results, though every gate and the race run had passed in make preflight. A cancelled required check costs a rerun, and the merge-queue entry runs the same job under the same limit.

Grounds

• pursued: the 45-minute ceiling and the warning at 35 minutes give the race stage a measured margin over the leg's 28-minute run; a merge-group run of that leg cancelled at its ceiling, or one reaching the warning, would show it wrong
