WIRE TYPES

ar.transfer.v1 (arrangement)

Records the legal arrangement governing a cross-border transfer — the legal basis (adequacy, SCCs, BCRs, or derogation), the parties, and the safeguards in place. TSA recommended.

ar.transfer.v1 (transfer)

Records an individual data transfer event under an existing arrangement. Subject carries a sha256 commit for the transferred data categories.

ar.transfer.v1 (tia)

Records a Transfer Impact Assessment — the supplementary measures analysis required post-Schrems II for non-adequacy transfers.

ar.transfer.v1 (suspension)

Records a suspension of transfers under an arrangement — triggered by a TIA finding, supervisory authority order, or material change in circumstances. TSA recommended.

WHAT IT PROVES

  • A legal arrangement was in force before transfers began (Merkle inclusion proof).
  • A Transfer Impact Assessment was conducted (TIA event in chain).
  • Transfers were suspended in response to a specific trigger (suspension event with cause).
  • The complete transfer lifecycle — arrangement, individual transfers, assessments, and suspensions (chain walk).

WHAT IT DOESN'T PROVE

  • The safeguards are effective against government surveillance in the recipient country.
  • The TIA analysis was thorough or correct.
  • The recipient actually respects the terms of the arrangement.
  • Adequacy decisions remain valid (political risk).
