From 743c6e9fcaeb5a96fae23373214b6c07e3d79011 Mon Sep 17 00:00:00 2001 From: Seongho Bae Date: Sun, 16 Aug 2026 21:18:24 +0900 Subject: [PATCH 01/27] fix(api): treat message audio/function_call null-empty as omit; fail-closed otherwise Chat history: message-level audio and legacy function_call are null/empty omit no-ops; non-empty fail closed with named errors (including tools passthrough). Tip substrate from #577 assistant refusal/annotations honesty.

Returning 400 was honest but left every streaming tool client failing. Pipe a single pool agent as chat.completion.chunk frames so concatenated mock content matches the non-stream JSON body, and pipe live provider text so tool_calls deltas survive. Keep include_usage, empty messages, and unsupported knobs fail-closed. Buyer next action: send stream=true on tool-calling requests; omit stream_options.include_usage.
