• 🔴 (15:42) User specified that failed output is never authoritative and must not reach accounting hooks.
• 🟡 (15:42) Candidate diff introduced Responses provider-failure handling artifacts including RESPONSES_PROVIDER_FAILURE_LOG, sanitizeResponsesProviderFailureTerminal, and validateResponsesProviderFailureTerminal.
• 🟡 (15:42) Candidate diff added recall-continuation state management using terminalRecallSnapshot, restoreResponsesAccState(state, terminalStateSnapshot), recallIndices.clear(), pendingRecalls.splice(...), lastContinuationSourceSequenceNumber, and continuationProviderFailure.event.
• 🟡 (15:42) Candidate diff tracked whether any non-recall function_call appeared for mixed-tools handling and set recallDetected = true when recall activity was identified.
• 🟡 (15:42) Responses event processing explicitly handled codex.rate_limits, diagnostic events "error" and "response.error", text events "response.output_text.delta", completed content tracked by doneContentParts, terminal-kind detection, and malformed terminal rejection via throw new Error("malformed Responses terminal event").
