## Pattern declaration

Primary pattern: Reviewer
Secondary patterns: Inversion
Why: 正規化の不整合は差分単体では見えにくく、既存コードとの比較が必要

## Guidance

- Compare new date/time formatting with existing patterns (e.g., mixing `format(date, 'yyyy/MM/dd')` with `date.toLocaleDateString()`, or `dayjs` vs `date-fns`).
- Check monetary amount display: inconsistent currency symbols, decimal places, or formatting utilities (`toLocaleString` vs `Intl.NumberFormat`).
- Check ID formatting: mixing hyphenated UUIDs with non-hyphenated, or mixing numeric IDs with string IDs in the same context.
- Check enum/status label rendering: if existing code uses a `statusLabel()` helper, flag direct string literals for status values.
- Flag when new code introduces a different normalization approach for the same data type.

## Non-goals

- 意図的なフォーマット差異(管理画面と公開画面の表示形式が異なる等)は指摘しない。
- テストコード内のハードコードされた値は対象外。

## Pre-execution Gate / 実行前ゲート

このスキルは以下の条件がすべて満たされない限り`NO_REVIEW`を返す。

- [ ] 差分にUI表示に関連するコード(date, amount, id, status labelの表示処理)が含まれている
- [ ] または差分にフォーマット処理関数の変更が含まれている

ゲート不成立時の出力: `NO_REVIEW: normalization-consistency — 表示正規化に関連する変更が検出されない`

## False-positive guards

- 既存パターンと同じユーティリティを使っている場合は指摘しない。
- コメントやdoc stringのみの変更は対象外。
