Generation time (32 tokens)	~1.5s
Total latency (incl. load)	~3.8s
Backend	CPU

Test Matrix

• Modalities: run, chat
• Backends: cpu
• Formats: gguf
• Scenarios per combination: 25

Artifacts

• evidence.json - Full test evidence (50 entries)
• junit.xml - JUnit XML for CI integration
• mqs.json - Machine-readable MQS score
• report.html - Interactive HTML dashboard

Methodology

Tests follow the Popperian Falsification protocol:

• Each test is a falsifiable hypothesis
• Outcome: Corroborated (survived refutation) or Falsified (refuted)
• All 50 hypotheses were corroborated

Recommendations

1. Production Ready: Yes, for CPU inference
2. Performance: Acceptable (5.9+ tok/s on CPU)
3. Stability: No crashes observed in 50 tests

Next Steps

• Run full qualification (1800 tests) for comprehensive coverage
• Add GPU backend testing
• Test additional quantizations (Q5_K_M, Q8_0)
