The original index-child scan checked if the child's blob data file existed under /blobs/sha256/<child>/data. That's wrong in a subtle way: registry:2 serves a per-repo manifest via the link file at <repo>/_manifests/revisions/sha256/<child-digest>/link, NOT by blob presence. When cleanup-tags.sh rmtrees a tag, the per-repo revision links for its index's children also disappear — but the blob data survives (GC owns that, and runs weekly). Result: blob present, link absent, API 404 on HEAD — the exact 2026-04-19 failure mode. Live proof: the registry-integrity-probe CronJob just found 38 real orphan children (including 98f718c8 from the original incident) while the previous fix-broken-blobs.sh scan reported 0. After the fix, both tools agree. The probe had been authoritative all along; the scan was a false-negative because it was asking the wrong question. Post-mortem updated to reflect the true mechanism (link-file absence, not blob deletion). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
