Module match_model 

MatchModel – ring buffer + hash table for longest match prediction.

Phase 5: Multi-candidate match finding with extended length verification. Finds up to 4 candidates via different hash functions, verifies each, and uses the one with the longest actual match length.

CRITICAL V2 LESSONS:

• Rolling hash must NOT be cumulative
• Confidence ramp must be linear (not step function)
• Length tracking must reset on mismatch
