+Advanced Limits Testing: qwen25-deposium-1024d
+
+This script pushes the model to its limits to discover:
+1. Cross-lingual instruction-awareness (FR→EN, EN→FR, mixed)
+2. Difficult and ambiguous cases
+3. Edge cases and failure modes
+4. Performance degradation thresholds
+
+Goal: Be HONEST about limitations for HuggingFace publication

+🔬 ANALYSIS:
+
+📊 Latin Scripts (FR/ES/DE):
+   Pass rate: 83% (5/6)
+   Average score: 0.961
+
+📊 Non-Latin Scripts (ZH/AR/RU):

+
+💡 CONCLUSIONS:
+
+✅ Latin-script languages (FR/ES/DE): Instruction-awareness WORKS monolingual
+✅ Non-Latin scripts (ZH/AR/RU): Instruction-awareness WORKS monolingual
+
+📉 Performance vs English Baseline (94.96%):
+   Latin scripts: --1.2% (96.1% vs 95.0%)
+   Non-Latin scripts: --3.4% (98.4% vs 95.0%)

+╚══════════════════════════════════════════════════════════════════════════════╝
+
+Based on these results, the model's monolingual instruction-awareness is:
+
+✅ GOOD for: Latin scripts (FR/ES/DE) monolingual use - 83% pass rate
+❌ POOR for: Non-Latin scripts (ZH/AR/RU) monolingual use - 83% pass rate
+
+This confirms: The model is optimized for English and other Latin-script
+languages, but NOT for non-Latin scripts even in monolingual mode.

+
+✅ GOOD for: Latin scripts (FR/ES/DE) monolingual use - {latin_rate:.0f}% pass rate
+❌ POOR for: Non-Latin scripts (ZH/AR/RU) monolingual use - {non_latin_rate:.0f}% pass rate
+
+This confirms: The model is optimized for English and other Latin-script
