From 743c6e9fcaeb5a96fae23373214b6c07e3d79011 Mon Sep 17 00:00:00 2001 From: Seongho Bae Date: Sun, 16 Aug 2026 21:18:24 +0900 Subject: [PATCH 01/63] 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.

(args/instructions/metadata/tlp hoist) #668 restored accept-path 200s but left omit-equivalent keys on the proxied body. Write back empty tool_calls arguments, pop blank Responses instructions, persist cleaned metadata, and hoist chat logprobs/top_logprobs before tools passthrough so providers see the omit-equivalent payload.

accepted Unicode letters and digits (café, 名前, Arabic-Indic digits), so the documented [a-zA-Z0-9_-]{1,64} check still forwarded illegal names and buyers saw an opaque provider 400. Require name.isascii() on tool.function.name, tool_calls function.name, message name, and response_format.json_schema.name (plus 64-char cap on json_schema.name). HTTP honesty locks Unicode reject and legal keep on chat and Responses. Request-body fuzz exercises both validators.
