ab-v9.1 misses were attention failures, not vocabulary failures: kinds
named literally in the brief (toolbar 5/10) still got hand-composed,
while anti-pattern-named kinds rarely missed. Token-match the subtask
label+elements text (plus the whole brief for single-section plans)
against the catalog, expand via a data-grounded synonym table, and
inject up to 6 nominations as an ELEMENT HINTS block with composite-
first and no-hand-compose rules. ab-v9.2 matrix: 51 FAIL->PASS vs 4
noise-shaped regressions; all four arms >=83% M3-pass, M5 adoption 96%.
