• 🟡 (13:52) Modified packages/gateway/src/pipeline.ts around lines 10145–10163: changed forwardedVisibleOutputIndices from Set<number> to Map<number, number> so each forwarded principal source index retains its visible index.
• 🟡 (13:52) Replaced wouldReindexForwardedOutput(newlyPrivateIndex) with assertForwardedProjectionStable(). The new assertion computes visibleOutputIndexMap() and throws when any recorded [sourceIndex, visibleIndex] no longer agrees with the current projection, protecting already-forwarded output from later reindexing.
• 🟡 (13:52) Added an async enqueueProjectedPrincipal helper in packages/gateway/src/pipeline.ts; principal-event forwarding paths were updated to call this helper, including a guarded call around line 10400.
• 🟡 (13:52) The modified recall-aware streaming logic retains the fail-closed RecallContinuationFailure("parallel_recall") path around line 10518 and continues resetting recallDetected = false around line 11718.
• 🟡 (13:52) Modified packages/gateway/test/openai-responses-recall-aware-stream.test.ts around lines 5829–5877 with a regression scenario containing visible text "already visible" and a follow-up callback that throws "must not run follow-up"; the existing test "fails closed when a lower-index recall follows visible output" moved to begin around line 5878.
