1.1.3

• Reduce 1.20.1 ray-loop allocation by using a mutable position only for set lookups and creating immutable selected positions only on first insertion. Preserve vanilla's affected-set insertion order, full shuffle and level RNG state.
• Reuse an immutable coordinate for consecutive modern ray samples in the same block. Resistance and selection callbacks still run on every sample, and retained callback positions stay stable across yields.
• Avoid repeated chunk-map lookups while ray samples remain in the current chunk. Discard both the current-chunk reference and slice cache at every yield so unloaded/replaced chunks are reacquired.
• Extend forced-yield shuffle/RNG, callback retention and chunk replacement regression coverage.
• Give live-test coordination files unique trial names to avoid replacing a file while the Windows client reads it. Add optional server JFR profiling for diagnosis; profiled runs cannot generate publication charts.
• Keep benchmark data and charts versioned so earlier measurements remain available.
