{"content":"Development diary: A2A caller trace and rating follow-up repair\n\nRepo: open-agent-connect\nBranch: codex/a2a-caller-unified-trace\nCommit: f8274b2925298a029fa9c138a0c91bd5447415ca\n\nContext:\nA live caller-side A2A service call succeeded and returned the provider markdown result, but the returned /ui/trace localUiUrl opened with an empty transcript. The same live call also published the rating record but failed to send the provider follow-up simplemsg once with `[-26]258: txn-mempool-conflict`.\n\nChanges:\n- Trace UI now reads `sessionId` and `traceId` from the URL on startup and auto-loads the matching A2A session.\n- Trace detail rendering now falls back to `inspector.transcriptItems` when legacy trace APIs do not expose top-level `transcriptItems`, which fixes the blank message pane for existing session-state traces.\n- Legacy/session-state transcript and status sorting now normalizes mixed second/millisecond timestamps.\n- Extracted trace fields `resultObservedAt`, `ratingRequestedAt`, and fallback `ratingCreatedAt` are also normalized to milliseconds.\n- Buyer-side service rating follow-up simplemsg writes now retry only explicit mempool-conflict failures with a bounded backoff.\n- Non-conflict `[-26]` transaction rejections are not retried and are surfaced immediately in trace state.\n\nTests and acceptance:\n- `npm run build` passed.\n- Focused acceptance tests passed: `node --test tests/a2a/traceProjectionUnifiedStore.test.mjs tests/ui/tracePageScript.test.mjs tests/ui/traceViewModel.test.mjs tests/daemon/servicePaymentBoundary.test.mjs` => 30/30.\n- Runtime suite passed after stopping live daemon interference: `node --test --test-concurrency=1 tests/cli/runtime.test.mjs` => 59/59.\n- Broader non-runtime suite passed in the earlier full test run: 761/761 before runtime daemon interference.\n- Live daemon smoke passed for `session-mon84fdf-1`: `/ui/trace?...&sessionId=session-mon84fdf-1` rendered both the caller request and the provider `上海天气预报` markdown result.\n- Live API smoke after rebuild/restart showed `ratingRequestedAt: 1777658848000` and 6 transcript items.\n\nReviews:\n- gpt-5.4 review found and verified the timestamp normalization gap; fixed.\n- gpt-5.4 follow-up review found the retry classifier was too broad for generic `[-26]`; fixed.\n- gpt-5.4 narrow final review found no remaining issue in the retry filter area.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
