🟡register_recovery(contact_name, contact_handle, quorum_rules, recovery_blob, idempotency_key)
Escrow an encrypted recovery blob: stored opaquely — we cannot decrypt it — for operator review, signed receipt proving its hash; quorum_rules govern release. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — $1.00, USDC on Base or Arbitrum One.
