• 🟡 (15:25) In packages/gateway/src/pipeline.ts:10324-10474, the Responses stream loop resets keepalive per frame, ignores empty data and [DONE], counts formatted SSE bytes against maxStreamBytes, rejects malformed JSON for response.* events, verifies payload type matches the SSE event, validates sparse coordinates, normalizes Codex events, validates lifecycle state, seeds implicit Codex items, consumes reference events, resolves output_index, and calls applyResponsesEvent() before checking maxRetainedStateBytes. If a lifecycle-only event crosses the retained-state limit, preserveLifecycleFailureState(state, outputIndex) runs before throwing SSEStreamLimitError("Responses retained state exceeded byte limit").
• 🟡 (15:25) In packages/gateway/src/pipeline.ts:10389-10463, reference events are consumed before output-index handling; recall calls are detected by function-call name RECALL_TOOL_NAME; sparse Codex function calls with an empty name are tracked in unresolvedToolIndices; resolving a visible function call removes its unresolved index and byte accounting and sets otherToolSeen = true.
• 🟡 (15:26) In packages/gateway/src/pipeline.ts:10477-10555, resolving a recall tool discards and promotes its deferred candidate and removes its unresolved index. Deferred events flush once both recallIndices and unresolvedToolIndices are empty. Recall and unresolved-tool events are suppressed while their bytes count toward maxDeferredBytes; recall bytes also count toward maxHiddenRecallBytes. Crossing either limit throws SSEStreamLimitError("recall stream exceeded deferred event limit"). Completed recall arguments are parsed on response.function_call_arguments.done, and completed recall items are collected on response.output_item.done.
• 🟡 (15:26) In packages/gateway/src/pipeline.ts:10557-10627, terminal events include response.completed, response.done, response.incomplete, and response.failed. Terminal processing strips hidden reference output, detects recall calls in terminal output, reconciles Codex terminal items through assertTerminalOutputMatches(), completes recognized recalls, resolves visible tools, then requires complete output lifecycles, reference lifecycles, and recall items before continuation.
• 🟡 (15:26) In packages/gateway/src/pipeline.ts:10639-10691, a terminal response with no pending recalls fails if sparse function identity remains unresolved or recall arguments remain incomplete; otherwise deferred events are forwarded, finalizeResponsesAcc(state) is called, the terminal event is forwarded, finish() receives whether the terminal event was response.completed, the reader is cancelled/released, keepalive is cleared, and the stream closes. A recall principal ending in response.failed or response.incomplete is rejected.
• 🟡 (15:26) packages/gateway/test/openai-responses-recall-aware-stream.test.ts contains sparse omitted-item-done coverage at lines 3241 and 3299 and unfinished-reasoning coverage beginning at lines 4195 and 4227.
• 🟡 (15:26) Test rejects malformed terminal reasoning ciphertext before recall execution constructs terminal reasoning with encrypted_content: 42; expected behavior is PUBLIC_RECALL_ERROR, recalls === 0, and followUps === 0.
• 🟡 (15:26) Test rejects unfinished reasoning omitted from output_item.done streams a response.reasoning_summary_text.delta of "partial" but an empty final summary; expected output contains response.failed.
• 🟡 (15:26) Test rejects unfinished reasoning when output_item.done omits summary streams a "partial" reasoning summary and then omits the summary field from response.output_item.done; expected output contains response.failed.
• 🟡 (15:26) Test rejects output text deltas that differ from the final text uses delta text "different" and final text "final" for msg_text_delta_mismatch.
• 🟡 (15:27) The Jujutsu working copy is clean and empty at change lrqlyykxvwoqrxzowonmmytxulyqmqlu, commit d890b184d786a4348e30bcdac7412baa7ae01ae9, with parent ce88c614c0ae55d229cb605aa7c7369d918d3650; conflict=false and empty=true.
