# Round 4 verdict: qwen3-coder-30b (LM Studio) — FAILED, not spec-compliant

Independently verified 2026-07-29:
- 2/29 pytest failures (ANTHROPIC_API_KEY not mocked in new tests that construct AnthropicProvider directly)
- 4 ruff I001 (unsorted imports), auto-fixable
- Real logic bug: get_provider("anthropic") with LLM_PROVIDER=lmstudio env returns LMStudioProvider,
  not AnthropicProvider — violates the spec's "if name is given, use it directly" requirement.
  Repro: ANTHROPIC_API_KEY=fake-key LLM_PROVIDER=lmstudio python -c
  "from runtime.providers.factory import get_provider; print(type(get_provider('anthropic')).__name__)"
  -> LMStudioProvider (should be AnthropicProvider)
- Frontend half (ComparePane.tsx, page.tsx) was genuinely gate-green (lint clean except 1 acceptable
  warning, build clean) and functionally equivalent to the other 3 rounds' frontends.
- Confirms tool-calling itself worked cleanly via LM Studio's engine (unlike round 2's raw
  mlx_lm.server failure) -- this was a real coding-quality miss, not a serving/tool-call issue.

Left un-fixed intentionally, as the raw comparison data point.
