• 🟡 (15:40) packages/gateway/src/pipeline.ts candidate introduces projection helpers/state including visibleOutputIndices, visibleOutputSources, syncVisibleOutputIndex(sourceIndex), enqueueProjectedPrincipal(...), assertForwardedProjectionStable(), projectionChanged, and projectionInvalid.
• 🟡 (15:40) Candidate stream handling recognizes "response.done" and validates response statuses against terminalStatuses.
• 🟡 (15:40) Candidate projection code tracks newlyPrivateRecallIndex, invokes assertForwardedProjectionStable(), and includes otherToolSeen when determining terminal stream behavior.
• 🟡 (15:40) packages/gateway/test/openai-responses-recall-aware-stream.test.ts expands its Vitest imports to include afterEach and vi, and adds response-event parsing plus expectVisibleOutputIndicesToMatchTerminal(output) consistency checks.
• 🟡 (15:40) Added test fixtures include IDs "msg_sparse_terminal_visible", "fc_lower_terminal_recall", and "resp_deferred_sparse_late_recall", use model "gpt-5.6-terra", and include a function-call argument delta of "{}".
• 🟡 (15:40) Added tests track separate recalls and followUps counters; at least one terminal-recall case asserts followUps is 0, and another follow-up callback throws new Error("must not run follow-up") if invoked.
• 🟡 (15:40) Added terminal-event coverage inspects response.failed, expects a response.completed event in another case, and exercises response.refusal.done.
