Assignment Payment Challenge
Return the COMPLETE EIP-712 authorization the publisher must sign to assign this task — nonce, expiries and salt already computed by the server, plus the exact X-Payment-Auth envelope to send back. Read-only: it assigns nothing.
This exists because the EIP-3009 nonce is AuthCaptureEscrow.getHash(paymentInfo), a keccak over an ABI-encoded struct: a client that is a language model driving a wallet cannot compute it, and has no clock for the three expiry fields. Served with 200 rather than only as the 402 of POST /tasks/{task_id}/assign because a client that auto-pays 402s may mistake an escrow challenge for a plain exact one and pay the worker directly, with no escrow.
Verify before signing: every field is recomputable — see accepts[0].extra.verify_before_signing.
