@docs-site/src/content/docs/reference/configuration/providers.md:
- Line 349: Update the retryOn429 reference and guide sections in the ja, ko,
ru, and zh-cn pages to document canonical Mistral openai-chat’s fallback of six
same-key replays at a 10-second interval when the option is absent. Clarify that
explicit configuration takes precedence and enabled: false disables the
fallback; preserve the existing translated content otherwise.
Review comments at @src/providers/key-failover.ts:
- Around line 616-617: Update the retry-policy fallback to use the shared
isCanonicalMistralChat predicate so its Mistral URL checks match
resolveMistralTransport, including trailing-slash edge cases. Narrow
isCanonicalMistralChat’s provider parameter to the adapter, authMode, and
baseUrl fields supplied by key-failover.ts, then pass those fields without
casting a partial provider.
Review comments at @src/providers/xai-transport.ts:
- Line 125: Update the provider-selection branch that calls
resolveMistralTransport so canonical Mistral Chat is selected by destination
rather than requiring providerName to equal "mistral"; rely on
resolveMistralTransport’s canonical-destination guard to leave other providers
unchanged, while preserving the existing XAI transport path.

Fixed in Both runtime regression cases fail on the previous commit and pass with the correction. All 58 Mistral cases pass. The expanded focused run passes 515 checks. Type, structure, privacy, whitespace, and documentation checks pass. The broader run has 42,698 passes, 113 skips, and 28 failures. All 28 failure names occur in the recorded upstream baseline. Full-suite and cross-platform checks remain unrun. @coderabbitai review |

- Line 352: Update the `retryOn429` documentation to state that Mistral shared
retry-deadline pacing is also disabled when `respectRetryAfter: false`,
alongside the existing `requestPacing.enabled: false` opt-out. Keep the
documented behavior aligned with `resolveMistralTransport`.

Fixed in 6899c6c. The configuration reference, provider guide, and architecture note now state that retryOn429.respectRetryAfter: false also disables Mistral shared pacing. The documentation build passes: 577 pages and 81,460 internal links. Architecture and whitespace checks also pass. Please verify the correction and resolve the addressed finding. @coderabbitai review |

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Hyphenate “patient-bounded.”
The changed line uses “patient bounded same-key 429 policy”. Use “patient-bounded same-key 429 policy” for the compound modifier.
Proposed wording
- patient bounded same-key 429 policy + patient-bounded same-key 429 policySource: Linters/SAST tools

Summary
A Mistral 429 response can end a Codex turn when
retryOn429is not set. The user must send "continue".prompt_cache_keyby default.For example, Mistral returns
429withRetry-After: 12, then accepts the next request:The retry keeps the same body and cache key. If the server delay exceeds the permitted wait, return the refusal with its delay.
This applies to the Mistral Chat endpoint at
https://api.mistral.ai/v1. Explicit settings take priority.Verification
