<p>IVF-SQ now pools residual training bounds, fuses residual
encoding, transposes output in bounded parallel batches, and reuses query heaps
with conservative L2 block pruning. Unified readers and language bindings also
cache decoded partitions within the existing reader memory budget. The <a
href="ivf-sq.html#benchmarks">SIFT1M/GIST1M/GloVe benchmarks</a> record build,
native query, and recall results with reproducible commands.</p>
<p>IVSQ v1 files remain compatible. Existing indexes receive reader
optimizations without a rebuild; retrain and rebuild to use the new
quantization bounds. Set the reader memory budget to zero to disable the SQ
cache; direct Rust <code>IVFSQIndexReader::open</code> remains uncached. See <a
href="api.html#reader-options">reader options</a> and <a
