🎯 Algorithm Selection Logic

OWLSOL uses intelligent heuristics to automatically select the best compression algorithm from both layers:

┌──────────────────────────────────────────────────────┐
│         Dual-Layer Algorithm Decision Tree            │
└──────────────────────────────────────────────────────┘

Is entropy > 7.5?
    ├─ YES → NONE (random/encrypted data)
    │
    └─ NO → Continue analysis
           │
           ├─ Has many repeated sequences? (>5% of data)
           │  └─ YES → DICTIONARY (Custom Layer)
           │
           ├─ Has long runs? (max_run > 10 OR avg_run > 3)
           │  └─ YES → RLE (Custom Layer)
           │
           ├─ Text-like? (unique_bytes < 128)
           │  └─ YES → HUFFMAN (Custom Layer)
