• 🟡 (12:57) Partial diff inspection of packages/gateway/src/pipeline.ts showed newly imported response-state helpers cloneResponsesAccState and finalizeUnsuccessfulResponsesAcc.
• 🟡 (12:57) Partial packages/gateway/src/pipeline.ts changes introduced or exercised provider-failure settlement machinery including continuationFailureReported, continuationProviderFailure, deferredEvents, terminalStateSnapshot, terminalRecallSnapshot, copied outputIdentities: new Set(outputIdentities), recallIndices.clear(), validation modes opts.validation ?? "public" and opts.validation === "codex", deferred-byte enforcement through maxDeferredBytes, and resetting transactionProviderUsage to { ...ZERO_USAGE }.
• 🟡 (12:57) A new comment in packages/gateway/src/pipeline.ts states that provider failures are emitted “only through the fixed public envelope.”
• 🟡 (12:57) Partial diff inspection showed recall-stream handling still includes the diagnostic text "recall stream ended before function arguments completed" internally, while nearby provider-failure output handling was changed; the supplied excerpt was elided and did not expose the complete control flow.
