### `normalize_jp_address`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Normalize and verify a Japanese postal address. Splits a raw Japanese address string into structured fields (prefecture, city, town, block number, building, room) and returns a verification flag plus lat/lng. Handles messy input: full-width chars, mixed hyphens, romaji, and building/room separation that generic parsers miss.
```
