test(writer): bit-width sweep property for bitpacked encode/decode#91
Merged
Conversation
Pin and round-trip every bit width 1..32 (u32) and 1..64 (u64): each case forces its width by including 2^W-1 and fills the rest with random W-bit values, covering the boundaries (1, 8, 31/32, 63/64) the existing curated arrays didn't hit deterministically. encode→decode must be lossless for all 96 widths.
