Release: turbovec 0.5.1 (Python) + 0.4.1 (Rust crate)

2026-05-18 18:12:32 +00:00 Performance release: block-level early exit for selective mask
searches. Selective allowlists now short-circuit the SIMD kernel at
32-vector block granularity (64-vector pair granularity on
AVX-512BW). Closes #30.Measured speedup at 1% selectivity, 100K vectors, d=1536:
- ARM (M3 Max): 0.98x -> 6.40x
- x86 (Sapphire Rapids 8c): 0.98x -> 12.67x
Speedup scales with index size — larger indices see larger
speedups as the fixed per-query overhead (rotation, LUT build, top-k
merge) amortizes.No change to existing public API. New Rust pub items for
hybrid-retrieval telemetry:BLOCKS_SKIPPED_BY_MASK(atomic counter),
blocks_skipped_by_mask(),reset_blocks_skipped_by_mask().No on-disk format change. Unmasked search latency unchanged.
