REPORT: TASK-20260828-0722-engstack-disk-reclaim (P1)
Status: DONE (dangling build cache pruned; follow-up QUESTION filed, see below).
Command run: docker builder prune -f (dangling only; no -a, no system/image/ volume prune; no containers touched)
df -h /
Before: /dev/sda1 274G 247G 14G 95% / After: /dev/sda1 274G 208G 53G 80% /
Disk space freed: +39G available (14G -> 53G).

Before: Images 128 32 108.2GB 44.71GB (41%) reclaimable Containers 36 26 638.3MB 296.1MB (46%) reclaimable Local Volumes 31 25 1.491GB 1.139GB (76%) reclaimable Build Cache 868 4 109GB 42.7GB reclaimable After: Images 128 32 108.2GB 44.71GB (41%) reclaimable Containers 36 26 638.3MB 296.1MB (46%) reclaimable Local Volumes 31 25 1.491GB 1.139GB (76%) reclaimable Build Cache 500 4 66.43GB 121.8MB reclaimable
Bytes reclaimed (docker-reported): 42.58GB build cache (868 -> 500 entries). Note: build-cache delta 109GB -> 66.43GB = 42.6GB; df avail delta ~39G (overlays share layers with tagged images, so df gain < cache delta).
Safety checks
- Running containers before: 26; after: 26. None stopped/removed.
- Images/volumes/containers untouched (counts identical).
Constraint check
Free space after = 53G / 274G = 19.3% < 20% threshold. Per TASK constraint, next-step proposal filed as QUESTION (not executed): inbox-pmo/QUESTION-20260828-disk-next-steps.md
