Comments and license text only: the amd64 kernel builds, every changed script parses.

dictionary_heat_optimization.h - Phase 2: Heat-Aware Dictionary Lookup

Inference-driven optimizations for dictionary lookup based on execution heat

patterns from the Rolling Window of Truth:

|

1. Heat percentile thresholds (25th, 50th, 75th)
|

2. Bucket reorganization by co-execution patterns
|

3. Heat-aware lookup strategy (search hot words first)
