note: >-
  Aerial Partners publishes no API versioning policy, no deprecation policy, no Sunset/Deprecation
  header contract (RFC 8594), no SLA and no status page — it has no public API to attach any of them
  to. What it does publish, and publishes well, is SERVICE lifecycle: dated end-of-life notices with
  migration schedules and data-retention terms. Those are recorded below. No StatusPage or
  Deprecation pointer is emitted, because neither an operational status page nor an API deprecation
  policy exists.

  headline: pafin acquires 株式会社Gtax; Gtax folds into Cryptact.
  detail: >-
    The Gtax profit-and-loss calculator and the Guardian tax-filing support business, both originated
    by Aerial Partners, sit in 株式会社Gtax, which pafin (operator of Cryptact) acquired as a
    subsidiary. Gtax is being merged into Cryptact. Aerial Partners itself remains a separate company
    under Lukka, selling AWA and ADM; its 特定商取引法 disclosure, last revised 2025-11-05, names only
    ADM and AWA.
