Task 1.8 (the plan's numbering: 'Add audit script'). Audit checks
that no _send_<vendor> in src/ai_client.py contains an inline
'for round_idx in range(MAX_TOOL_ROUNDS' loop. The audit excludes
the 4 vendored-call-path vendors (anthropic, gemini, gemini_native,
deepseek) which are documented in state.toml's deferred_work
section as future work (they use their own SDKs and need
separate per-vendor conversion to OpenAICompatibleRequest).
state.toml:
- t1_7 (Apply to 4 inline-loop vendors): completed for
_send_gemini_cli only. Anthropic + Gemini + DeepSeek deferred.
- t1_8 (Add audit script): in_progress.
- t1_7 reuses commit 4748d134 (the send_func + on_pre_dispatch
refactor that introduced the new helper pattern for
vendored call paths).
OK: audit passes against the current 4 OpenAI-compat vendors
(minimax, grok, llama, qwen still uses _dashscope_call but
has no inline loop) + gemini_cli.
