How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughThe change adds model retry observability across the runner, handlers, WebSocket transport, Redux state, and inline notices. It also centralizes the retry limit and keeps retry status events local to the WebSocket connection. ChangesModel Retry Status
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to A failed model attempt can leave partial text in the response, causing duplicated content after retry, while an active retry status may also be briefly hidden in the interface. These are localized issues, but the response duplication should be fixed before merge. Sequence Diagram(s)sequenceDiagram

In `@internal/runner/runner.go`:
- Around line 656-660: Update the retry branch handling adk.WillRetryError in
the stream-processing flow to remove or reconcile all partial output from the
failed attempt before continuing, including responseText and OnAgentText/UI
state, so the successful retry cannot duplicate its prefix. Add a regression
test covering one emitted chunk, WillRetryError, and a successful retry,
asserting the final response and observed UI text contain only the successful
attempt.
In `@web/src/components/RemoteConnectionNotice.tsx`:
- Around line 49-53: Update the notice-selection logic in RemoteConnectionNotice
so modelRetry renders when notice is absent or has status ready, while active
connection failure notices retain precedence. Adjust the early-return and
branching conditions around notice and modelRetry without changing other status
behavior.
- Line 65: Update both inline Icon renderers in RemoteConnectionNotice to
include explicit Tailwind h-N and w-N size classes, while retaining the existing
remote-connection-notice__inline-icon class for non-size styling.

Summary
The PR wires model-retry observability (RetryObserver in internal/model, optional ModelRetryHandler, task-scoped web slice/notice) and fixes run-abort on eino WillRetryError. Go build/tests and web typecheck/tests pass. One verified defect: continuing past a mid-stream WillRetryError keeps the failed attempt's already-streamed text, duplicating it in the live transcript and result.Response (verified with a probe test: model streams "Hello" then 429, retries with "Hello world" → Response="HelloHello world", OnAgentText=["Hello","Hello world"]). Everything else (cloud local-only classification, ws routing, i18n keys, store clearing) checks out.

- go generate ./internal/model/... + ./internal/theme/..., stub internal/web/dist/index.html, then `go build ./...` — pass
- `go test ./internal/runner/ ./internal/model/ ./internal/handler/ ./internal/cloud/ ./internal/agent/` — all ok (includes new model_retry tests)
- Wrote+ran probe test in internal/runner (deleted after): mid-stream 429 after partial chunk → result.Response="HelloHello world", OnAgentText=["Hello","Hello world"]
- Read eino v0.9.9 adk/retry_chatmodel.go and adk/wrappers.go: WillRetryError emitted via genErrWrapper only for mid-stream errors with retries left; pre-stream errors retry silently
- web: `npx vitest run` — 143 tests pass (2 suite env failures from unbuilt jcode-ui dist, pre-existing tooling prerequisite; unrelated files)
- web: PR's new tests (modelRetry.store, RemoteConnectionNotice, ws, wsBridge) — 20/20 pass; `npx tsc --noEmit -p tsconfig.app.json` clean after building packages

- Inspected web/src/lib/ws.ts TASK_ID/BACKGROUND/PENDING_FOREGROUND sets, wsBridge.ts clearWaiting on agent_done, store.ts slice semantics — mirror remote_connection_status correctly
- Verified i18n keys modelRetry.* and remoteConnection.inline.* added to all 5 locales; MaxAttempts=DefaultMaxRetries(5) matches eino BackoffFunc attempt range 1..5

Summary
The PR wires model-retry observability (RateObserver -> handler.EmitModelRetry -> web model_retry_status -> Redux slice -> inline notice) and stops the runner from failing on eino WillRetryError events. Go tests (agent/cloud/handler/model/runner), web vitest (159 tests) and web tsc all pass, and the cloud local-only gate correctly excludes the new event. Two P3 defects found: (1) continuing past a WillRetryError after a mid-stream failure duplicates the already-streamed partial text in every transport and in result.Response (verified empirically); (2) the waiting notice hardcodes MaxAttempts=DefaultMaxRetries(5), which is wrong for sub-agent retries that run under the same context observer with MaxRetries=3.

No findings met the configured confidence threshold.
Summary
No verified defects. The retry-status plumbing is correct against the eino v0.9.9 API: the ShouldRetry streaming guard only retries before output (preventing duplicated prefixes), the mutex-guarded observer preserves waiting-to-ready ordering across goroutines, exhausted retries surface RetryExhaustedError rather than being swallowed by the new WillRetryError continue branch, and all five retry-config sites pair MaxRetries with the matching backoff reporter. The web routing change only drops benign events (agent start, local-echo user message) during the new-chat gap, and model retry status is correctly task-tagged and excluded from the cloud relay. Full Go build and test suite pass; web vitest could not run in this environment (no pnpm or node_modules) and was reviewed manually.
