-### Performance Requirements -- **Regex engine**: Must process 10KB text in <200μs (currently ~2.4ms) -- **Core package size**: Keep under 2MB (down from ~8MB in v4.0.x) -- **Performance advantage**: Maintain 150x+ speedup over spaCy (currently 190x validated) -- **Regression threshold**: Performance cannot degrade >10% from baseline -
