### Tool changes

- 2026-10-16 `jp_fsa_registry_lookup` changed (description, outputSchema)
  - before: Is this business (name, registration or 13-digit corporate number) on a Japan FSA register or warning list? Exact match (optional domain) against: registered financial instruments, crypto-asset exchange, electronic payment instruments, funds transfer and money lending businesses, and FSA warnings to unregistered businesses. Returns matches, unconfirmed name candidates, domain links only when a list states them, and which lists were checked as of when. Absence does not mean safe; no advice.
  - after: Is this business (name, registration or 13-digit corporate number) on a Japan FSA register or warning list? Exact match (optional domain) against FSA registers (financial instruments, crypto-asset exchange, electronic payment instruments, funds transfer, money lending) and warnings to unregistered businesses. Returns matches with registration type, entity tie (domain alone: unverified), name candidates and as-of dates. Stated scope only; no warning match is not proof none exists. No advice.
- 2026-10-15 `fsa_enforcement_by_corporate_number` added
  - Which rows of the Japan FSA case list of adverse administrative actions (business improvement or suspension orders and similar, by the FSA and Local Finance Bureaus, fiscal 2002 to the list's as-of date) state this 13-digit corporate number? Rows as published: date, action type, legal basis, business type, lifted flag, with the list version, SHA-256 and the scope of what was checked. Zero rows is not_found_in_checked_records with that scope; after the as-of date is unknown. No name search.
- 2026-10-12 `fsa_register_changes` added
  - Which entries were added to, dropped from, changed in or returned to Japan FSA registers and warning lists since a date? From this service's own record of list versions (the FSA publishes only current lists). Each change has the list, registration number, name as published (personal names withheld), before/after fields, observed_at and the list as-of date. Reasons are not published or inferred. History starts at tracking_since; free window: last 30 days.
