Remove the eager GPU lane transpose from the Patched array. Patches are now kept in their natural sorted layout with one chunk offset per 1024-element chunk, mirroring the Patches helper, and execute/slice/take/compare/filter reuse the existing untransposed patch machinery. The transpose count (n_lanes) is retained as metadata so the data-parallel GPU transpose can be re-added in the future without a format change. Signed-off-by: Claude <noreply@anthropic.com>
Add SparsePatchedPlugin which, when the experimental Patched encoding is enabled, deserializes a primitive Sparse array as a Patched array over a constant fill. A Sparse array is logically patches on top of a constant, so this reuses the same externalization shim already used for BitPacked and ALP. Non-primitive (bool/varbin/struct/fixed-size-list) and nullable-patch sparse arrays remain Sparse, since Patched only represents primitive inners with non-null patch values. Signed-off-by: Claude <noreply@anthropic.com>
Microbenchmark isolating loop ordering for patched bitpacked decode: unpack every 1024-block then scatter all patches, versus unpacking one block and patching it while still hot in cache. Both do identical work, so any delta is cache locality. Fused wins 20-40% once the output exceeds L2, peaking around moderate patch density. Signed-off-by: Claude <noreply@anthropic.com>
