Ships BEFORE the disk-layout merge it exists for, and is harmless on a box that never gets it. The mp1 partition was a BULKHEAD as well as a ceiling: it kept a runaway capture from filling the space the container runtime needs, because /var/lib/docker was a different filesystem. After the merge it is the same one, and a full Docker data-root is a stopped box. The floor sits in captureAllRecoveryUnits, checked BEFORE anything is written: below the reserve, that ONE app's capture is refused, its previous unit is left byte-identical, the R-158 alert fires with the space figures, and the loop continues. Two terms whichever binds first (97% used / 1 GiB free) in fillwatch's shape, deliberately BEYOND its critical band (95% / 2 GiB) so the customer is always warned before a refusal can happen — a floor that fires before its own warning is a silent failure wearing a threshold. Headroom, never unit size: a per-unit cap would be R-163 rebuilt inside one volume. Refuses, never deletes: nothing here is generational, so pruning could only destroy a different app's only local copy; pruneStalePrimaryDirs is an orphan sweep, not retention, and must not be repurposed. Tests 1184 -> 1191. One fixture strengthened mid-red-proof: the "old 20 G ceiling is gone" test sat at exactly 20 GB and survived a literal UsedGB > 20 cap — hollow. Now 120 GB, and the mutation fails it.
