Measured over six hours after the last change: zero burst clears fired, while deb still died of ENOSPC between polls. Both 30 min and 10 min lost the same race — three concurrent Rust builds fill the disk and drain it again inside the interval, so every poll landed on a healthy df and the guard concluded all was well. Two changes, both aimed at that gap rather than at the symptom. The interval goes to 2 min: the script is a few docker calls and no-ops in about a second, so sampling five times more often costs nothing worth counting. And MIN_FREE_GB goes 45 -> 60, because the clear only reclaims idle images (~18 G measured) while three jobs can eat the remainder inside one interval — a guard that waits for "tight" has already lost. It has to act while there is still room to act in. This narrows the window; it does not close it. With a 43 G image baseline on a 172 G disk, three concurrent heavy jobs are working inside ~129 G and can exceed it. Sub-interval spikes are a polling problem, and the honest fixes are fewer concurrent replicas or more disk. Deployed to home-runner-1; deployed md5 matches the repo.
