pub fn compute_dict_hash(entry: &StreamDictEntry) -> [u8; 32]Expand description
Computes the canonical BLAKE3 hash of a StreamDictEntry.
The hash is domain-separated by a crate-internal prefix, writes the numeric slot
big-endian, and length-prefixes the data-class and identifier strings so a slot remapped to
a different class or identifier cannot frame to the same byte stream. Store the returned
bytes alongside the record; do not add a hash field to the struct itself.
