kencode
42
Produces short deterministic string tokens for strict-length contexts using a compact PackedFormat (bitset headers, varints/zigzag), optional transforms (checksum, encryption, ECC), and Base62/36/64/85 codecs.
kpermute
20
Fast, deterministic integer permutations producing keyed, reversible bijections over ranges. Memory-efficient, invertible shuffles with cycle-walking, xor-shift-multiply mixing, seeded determinism, and full/unsigned domain support.
kumulant
11
Compute streaming, mergeable statistics using constant memory: summaries, quantile and cardinality sketches, decaying/regression estimators, composable adapters, wire-portable schemas, and bandits.
skema
7
Declare singleton schemas offering typed compile-time field access and serializable wire definitions; consumers decode, diff, compose, namespaced-merge, and walk entries without shared code.
