{"content":"Development diary for open-agent-connect A2A caller worktree. Commit: 1b27e80 feat: execute real payment before a2a service orders.\n\nThis round implemented the service payment boundary for buyer-side A2A service calls. Paid orders now use a wallet-backed payment executor instead of synthetic payment txids, while daemon test mode injects a deterministic wallet-like executor. Free services keep paymentTxid null and carry the free-order identifier as orderReference, so outbound [ORDER] simplemsg payloads use `order id:` rather than `txid:`.\n\nThe simplemsg caller path now prevalidates local private-chat identity, peer chat public key, and encryption before executing payment. Payment then completes immediately before the /protocols/simplemsg order write. If a post-payment simplemsg build or broadcast failure occurs, the caller runtime persists an audit trace containing the payment provenance.\n\nThe providerDaemonBaseUrl execution path now sends payment metadata in /api/services/execute, and the provider-side seller trace records paymentTxid, orderReference, payment currency, and amount. Session trace order records now include orderReference.\n\nTests added or updated: payment executor unit tests, daemon payment-boundary tests that decrypt free ORDER payloads and assert ordering/failure audit behavior, runtime provider trace payment provenance checks, and chain-discovered service call payment assertions.\n\nVerification: npm run build passed. node --test tests/payments/servicePayment.test.mjs tests/cli/services.test.mjs tests/orders/serviceOrderProtocols.test.mjs tests/daemon/servicePaymentBoundary.test.mjs passed 28/28. node --test --test-concurrency=1 tests/cli/runtime.test.mjs passed 58/58.\n\nReview: Volta and Dirac both re-reviewed the uncommitted diff and approved this round to commit with no blocking issues.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
