• 🔴 [enforced-stream-behavior] (17:20) User reaffirmed that the recall-aware Responses stream never forwards response-side item_reference lifecycle events. Test never forwards response-side item_reference lifecycle events at packages/gateway/test/openai-responses-recall-aware-stream.test.ts:1978-2019 verifies neither streamed output nor completedResponse contains item_reference.
• 🟡 (17:20) Search results in packages/gateway/test/openai-responses-recall-aware-stream.test.ts identified item_reference validation tests: rejects an item_reference missing output_item.done at line 2022; rejects reuse of an item_reference output index at line 3793; rejects reuse of an item_reference index in a continuation at line 4203; rejects reference identities reused by later output items at line 4602; rejects reference identities colliding with synthetic markers at line 4639; and rejects continuation references colliding with principal identities at line 4972.
• 🟡 (17:20) Additional stream-integrity tests visible in packages/gateway/test/openai-responses-recall-aware-stream.test.ts cover content_part.done changing initial part content, completed output receiving later content, conflicting output_text.done or content-part text, conflicting reasoning_summary_text.done, conflicting reasoning_text.done, and late deltas after an item is done.
