Expand description
The word-wise FNV-1a hash the pack’s checksum and a bundle’s
fingerprint share: FNV-1a’s constants over 64-bit words (the last few
bytes one at a time), each step followed by a shift that folds the
high bits into the low ones. Each step is a bijection of the hash so
far, so any one word changed changes it. Every integer is a u64,
whatever the platform. A frame’s snapshot hashes a painted picture with
it too (ADR-0078).
