0.13.2

Version 0.13.2

Changelog

• Added BmHash128Throughput (128-bit bounded-range throughput) and guarded the 64-/128-bit benchmark paths by HasGetHash64/HasGetHash128.
• Reworked the measurement report around the latency (ns at exact length) / throughput (GiB/s over the Short/Web bounded distributions) split: each renders as chart + table per hash width, absent sections dropped; the report re-distills a bundle from its raw on read, so old bundles still yield latency tables and bundles need no re-packing when the tool changes.
• Reworked the hash mixed-length benchmark: dropped the hash-indexed key walk that collapsed into a rho-cycle (near-zero anomalies) and added BmHash64Throughput reporting bytes/s over two documented length distributions (Short ≤128 B, Web ≤4096 B) truncated to each upper bound; the per-exact-length BmHash64/BmHash128 remain the latency view. Distributions are exported as the throughput_dists context.
• Added a compare command reporting per-case Δ% and a geomean between two datasets.
• Made tables/plot/compare/quality accept a bundle .tgz or a results JSON, positionally or via --results/--bundle.
• Added plot --kind (throughput/latency/all) and --scale (log-log/linear-log).
• Expanded the benchmark kFullSizes and swept latency over the full set (dense ns-vs-length latency curve).
• Added a quality command generating the overview + SMHasher3 Results tables from hash_algorithms.json and a measured bundle; --check gates them.
• Added a consistency command verifying same-source-SHA bundles agree on SMHasher3 verdicts.
• Fixed SMHasher3 parsing: a bad name or crash reads as ERROR not a false PASS; score and failing families parse from the Summary; legacy names aliased.
• Integrated mbo/hash/measurements as a normal dev package (still release-stripped) with a quality_sh_test gating the tables; test CI fetches the LFS bundles.
• Added a no-deps-on-measurements pre-commit guard.
• Ported mumbo (64-bit) to Starlark (hash.mumbo), byte-identical to C++; hash.bzl now offers mumbo, dumbo, and fnv1a.
