• 🟡 (10:47) Candidate diff statistics were 3056 insertions(+), 495 deletions(-) across 6 files: packages/gateway/src/pipeline.ts 343 changed lines, packages/gateway/src/stream/openai-responses.ts 1024, packages/gateway/test/openai-responses-recall-aware-stream.test.ts 1152, packages/gateway/test/openai-responses-stream.test.ts 882, packages/gateway/test/pipeline-streaming.test.ts 147, and packages/gateway/test/recall-codex-stream.test.ts 3.
• 🔴 (10:47) User stated failed output is never authoritative and must not reach accounting hooks.
• 🔴 (10:47) User stated failed usage/accounting never depends on client demand.
• 🟡 (10:47) packages/gateway/src/stream/openai-responses.ts introduces or exposes failure-handling primitives: cloneResponsesAccState() at line 582, restoreResponsesAccState() at line 588, PUBLIC_GATEWAY_ERROR = "Gateway request failed" at line 598, sanitizeResponsesProviderFailureTerminal() at line 605, validateResponsesSourceSequence() at line 653, and finalizeUnsuccessfulResponsesAcc() at line 1031.
• 🟡 (10:47) In packages/gateway/src/stream/openai-responses.ts, sanitized provider failures replace state.terminalResponse with a copy of sanitizedFailure.parsed.response; provider resp.id and resp.model update state only when no sanitized failure exists.
• 🟡 (10:47) packages/gateway/src/pipeline.ts imports cloneResponsesAccState, restoreResponsesAccState, sanitizeResponsesProviderFailureTerminal, validateResponsesSourceSequence, and finalizeUnsuccessfulResponsesAcc; principal-path integrations appear around lines 10161–10312, continuation-path integrations around lines 10612–10960, and unsuccessful finalization also appears at line 11840.
• 🟡 (10:47) Search found 46 references associated with source-sequence validation, provider-failure sanitization, state cloning/restoration, and unsuccessful finalization across packages/gateway/src/pipeline.ts and packages/gateway/src/stream/openai-responses.ts.
