Five layers: live-value match across all 77 revs / 765 reachable blobs; the whole
object store including the 2 dangling blobs (one synthetic sk-shaped fixture,
never committed on any ref); 21 provider shapes with every hit triaged; an
entropy scan of HEAD; all 23 git-lfs payloads (81 MiB) scanned as bytes.
Gate gap noted: hf_/npm_/pypi-/AIza/basic-auth-URL shapes are absent from
.githooks/pre-commit. Quoting the fixture literal in this commit message was
rejected by the gate, so it is described instead.
Also chmod 600 ~/.config/secrets/hf_token_write (was world-readable).
