Composes into replayable evidence of \"final at window Y\" for a correspondent bank or auditor. Verify-only -- never asserts on-chain settlement it did not observe. The receipt does not yet carry a receipt:// resolver link (pending the N1 MCP Resources work); this is a planned upgrade, not a missing requirement.",
