/**
 * tx-post-escrow-live.test.ts — RED phase tests for buildPostEscrowTx() with LiveOgmiosProvider
 *
 * The live path uses lucid-evolution to produce real Cardano CBOR instead of
 * synthetic JSON-in-hex. Ogmios fetch is fully mocked; lucid-evolution is
 * exercised for real (no mocking of TxBuilder).
 *
 * Existing MockChainProvider tests in tx-post-escrow.test.ts are NOT modified
 * — the Tier-1 mock path must continue to pass without regression.
 *
 * Coverage:
 *   A. Output CBOR shape (Conway-era prefix bytes)
 *   B. Inline datum present at escrow script output
 *   C. Locked value calculation
 *   D. Required signers / collateral
 *   E. Validity range (deliver_by upper bound)
 *   F. Rejection paths (buyer==supplier, empty messages, advert not found, retired, payment mismatch)
 *
 * M1-F-4 RED — tests fail until Catherine implements the live CBOR path.
