Operation lookup

Lookup prior mutation by idempotency key.

Path

GET /operation/{idempotency_key}

Response

{
  "found": true,
  "status": "succeeded",
  "currency_code": "IDR",
  "amount_minor": 10000,
  "idempotency_key": "mini_app_order:1:debit",
  "remote_reference": "wallet-op-123",
  "balance_minor": 90000
}

Rules

• found = false when operator has no matching record
• status semantics match mutation response semantics
• lookup is required for recovery from timeout or network ambiguity
