-### INFERENCE COMPLIANCE
-
-- [x] Uses OpenAI client (`from openai import OpenAI`)
-- [x] Reads API_BASE_URL from env
-- [x] Reads MODEL_NAME from env
-- [x] Reads HF_TOKEN from env
-- [x] No hardcoded tokens in inference.py
-- [x] success=true for scores > 0.10
-
-### FEATURE VERIFICATION
-

-- [x] Adversarial injection resistance tracked
-- [x] Multi-file repository works for hard task
-- [x] inspect_file action works
-- [x] inspect_lines action works (with 40-line limit)
-- [x] Cross-file bug matching works
-
-### TESTS

-## Final Verdict
-
-### 🟢 **SUBMIT**
-
-**Confidence Score: 97/100**
-
-### Remaining Risks (Low)
-
-1. **HF Space may sleep** — Free-tier HF Spaces go idle after inactivity. The validator should wake it on `/reset` ping, but there may be a ~30s cold start.
-2. **Requirements not version-pinned** — Not a disqualification risk but could cause issues if a breaking update ships to a dependency.
-3. **`openenv validate` not tested locally** — `openenv-core` package not installed in this environment. The space is live and responding correctly which is the primary validation.
