• 🔴 (14:07) User supplied a further continuation of pipeline.ts, with visible line anchors spanning 10386–11427, covering Responses lifecycle validation, recall detection, hidden-recall limits, terminal-event handling, anchor extraction, recall execution, continuation streaming, output-index shifting, usage merging, and cross-continuation identity checks.
• 🔴 (14:07) pipeline.ts:10386 calls validateResponseLifecycle(state, event, parsed);.
• 🔴 (14:07) Recall-processing paths set recallDetected = true at multiple points, including visible anchors around lines 10404 and 10442.
• 🔴 (14:07) Tool-item handling checks whether implicitItem?.type === "function_call" and tracks whether a visible tool was resolved through resolvedVisibleTool.
• 🔴 (14:07) Hidden recall output is bounded by comparing hiddenRecallBytes > maxHiddenRecallBytes.
• 🔴 (14:07) Event handling has a specific branch for event === "response.output_item.done" and marks principal stream completion with principalReadFinished = true.
• 🔴 (14:07) Validation behavior includes a dedicated opts.validation === "codex" path and tracks non-recall tool activity with otherToolSeen = true.
• 🔴 (14:07) A code comment states: No recall — forward the terminal event verbatim.
• 🔴 (14:07) Recall context construction initializes const anchorTexts: string[] = []; and passes query: recall.query.
• 🔴 (14:07) Deferred-event cleanup uses deferredEvents.length = 0.
• 🔴 (14:07) Continuation execution propagates signal and can classify failures as continuationFailureCategory = "follow_up_protocol" or continuationFailureCategory = "follow_up_transport".
• 🔴 (14:07) Continuation candidate metadata includes transactional: boolean and conditionally adds { candidateIndex }.
• 🔴 (14:07) Held continuation events are cleared with heldContinuationEvents.length = 0.
• 🔴 (14:07) Continuation parsing tracks other tool activity with let contOtherTool = false; and remaps output positions through shiftedOutputIndex(...).
• 🔴 (14:07) Continuation event validation explicitly references ce !== "response.output_item.done" and identifies recall calls with item.name === RECALL_TOOL_NAME.
• 🔴 (14:07) Continuation completion checks unresolved tool state via contUnresolvedToolIndices.size > 0.
• 🔴 (14:07) Usage-accounting error handling logs "failed to merge recall continuation usage for accounting".
• 🔴 (14:07) Final continuation reconciliation iterates contState.rawItems.values() and detects "duplicate Responses item identity across continuation".
