• 🔴 (15:40) User established the projection invariant: “Always accumulate into the internal state for postResponse.”
• 🔴 (15:40) User required recall interception to “never expose non-semantic %s frames after recall interception.”
• 🟡 (15:40) Candidate diff in packages/gateway/src/pipeline.ts applies the post-response accumulation invariant in at least two separate stream-processing paths, each marked with the exact comment // Always accumulate into the internal state for postResponse.
• 🟡 (15:40) Candidate projection logic checks both state.rawItems.has(sourceIndex) and state.items.has(sourceIndex), tracks forwarded positions, and determines newly private output with const newlyPrivate = !recallIndices.has(outputIndex);.
• 🟡 (15:40) Candidate adds projection handling that rewrites emitted event payloads using JSON.stringify({ ...parsed, output_index: visibleIndex }), mapping source output indices to visible indices.
• 🟡 (15:40) packages/gateway/test/openai-responses-recall-aware-stream.test.ts adds coverage for sparse visible output, including content { type: "output_text", text: "sparse visible text" }, and asserts that output does not contain "private result".
• 🟡 (15:40) Existing continuation usage-overflow test was adjusted from textItem(0, "Here is the answer from the continuation.") to textItem(7, "Here is the answer from the continuation."), exercising a sparse output index.
• 🟡 (15:40) Candidate tests include sparse already-visible output via textItem(7, "already visible", "msg_sparse_visible").
• 🟡 (15:40) Candidate tests assert an invalid projection can produce { status: "failed", output: [] }.
• 🟡 (15:40) Candidate tests exercise response.function_call_arguments.delta, recall call counting through recallCalls++, both initial and continuation stream sources, and post-interception filtering of non-semantic frames.
