 join closes a 268-row gap (DWPR/DWHD residue the prefix buckets missed).
 
+**Codex second-model check (2026-08-30):** confirmed "exact normalized-code membership is
+the correct primary provenance test; prefix membership would wrongly condemn legitimate
+scraper-native DWAG-376xxx" and the 33,762/772/65 split is "strongly supported" by the
+exact 772-row reconciliation + bucket-perfect ledger counts. It flagged one concrete risk —
+a *second* mint campaign outside this 11,725-row ledger (the reverted **Romo-491**,
+`DWRO-30476..30966`). **Verified empty:** there are ZERO current blank Romo rows carrying
+any `DWRO-` code, so that campaign does not intersect the backlog. (The ledger's 11 `DWRO`
+entries are the Bucket-A "Romo 11" mint, distinct from the 491.) Other codex-noted guards —
+Unicode-dash / case / whitespace normalization — are handled (join upper-cases + trims +
+strips unit suffixes); a duplicate-in-ledger guard already fails closed.

 **Chain-of-custody caveat (Steve to confirm):** the ledger FILE (`/tmp/TK-10896-phase4-
 ledger.jsonl`) is integrity-verified (SHA-256 + row-count + no-dups) and internally
 conclusive, but I could not tie it to the canonical Kamatera `sku_repair_p4_20260826`
