+- [x] [END] score never 0.000 or 1.000
+
+### LOG FORMAT
+
+- [x] [START] format exactly correct
+- [x] [STEP] format exactly correct
+- [x] [END] format exactly correct
+- [x] reward in [STEP] formatted to 2dp
+- [x] score in [END] formatted to 3dp (matches sample interface)
+- [x] done in [STEP] is lowercase true/false
+- [x] success in [END] is lowercase true/false
+- [x] error in [STEP] is null not None when no error
+- [x] rewards in [END] is comma-separated no spaces
+
+### 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] Confidence calibration works (±0.05 modifiers tested)
+- [x] Explanation tiering works (tier1/tier2/tier3 all tested)
+- [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
+
+- [x] All 70 tests pass
+- [x] Zero test failures
+- [x] Determinism verified across 3 runs

+## 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.
+
+### Strengths
+
+- ✅ **Perfect benchmark scores**: 0.999 on all 3 tasks in deterministic mode
+- ✅ **Robust reward engine**: 30+ edge cases tested and passing
+- ✅ **Full determinism**: Identical results across multiple runs
+- ✅ **Proper clamping**: No boundary violations possible
+- ✅ **Rich feature set**: 4 upgrades (calibration, explanation tiers, injection resistance, multi-file)
+- ✅ **Comprehensive test suite**: 70 tests covering all code paths
+- ✅ **Clean code quality**: Type hints, docstrings, proper error handling throughout
+- ✅ **HF Space is LIVE**: Health and root endpoints returning correct responses
