 | F-12 l06 current package | **Blocked on a capture.** Kewpie serves the superseded design for JAN 4901577083600, so the current package cannot be enrolled from the official URL. The text lane ranks l06 first on all 4 shelf facings but abstains below the accept line, so no wrong label is shown. |
 | F-13 stale status / swallowed exception | Done. The fixture returns the matcher's `(scores, details)` shape; zero swallowed callback exceptions. |
 | F-09 re-evaluation with provisional labels | **Postponed as §8 specifies** — it is a dependency of E-7, which needs Tier-3 recordings that do not exist yet. |
+| Enrollment protocol: versioning | Done. Every eval report records `catalog_hash`, `labels_hash`, `image_hash`, `code_revision`. The catalog hash covers the CSV bytes and the view names, not image bytes. |
+| Enrollment protocol: sibling flag | Done. `rebuild_catalog` reports cross-SKU near-duplicates as text-discriminated siblings (cosine ≥ 0.98, same shape). Reported, not refused: they are legitimately different products, and only package text separates them. |
+| Enrollment protocol: completeness rule | Done. `--shelf-tags` turns it into a `live_ready` verdict; without the shelf's SKU list the verdict is `unknown`, not a guess. |
 
 Two defects found while wiring the lanes into the live path, both fixed:
 `live` re-sorted the local lane's scores by value, which discards the lane's own
