Live run on the registry VM surfaced 632 "orphaned" index children across
156 indexes in the pull-through caches (ghcr, immich, affine, linkwarden,
openclaw). These aren't bugs — pull-through caches only fetch what's been
requested, so missing arm64 / arm / attestation children are normal partial
state. Scanning them generates noise that would mask the real signal from
the private registry (where we push full manifests ourselves and a missing
child IS always a bug — the 2026-04-13 + 2026-04-19 failure mode).
Change: index-child scan is now gated on registry_name == "private". Layer-
link scan still runs across all registries (missing blob under a live link
is always a bug, regardless of pull-through semantics).
Verified: live run now reports 0 orphans in private registry — consistent
with the hot-fix rebuild of infra-ci:latest earlier today. Layer scan
still inspects 425 links across all registries and finds 0 orphans.
