test(writer): property-based round-trips for Delta/FoR/ZigZag/AlpRd#89
Merged
Conversation
Seeded random inputs (+ curated edges: 0, ±1, MIN/MAX, near-extremes) through encode → decode asserting decode(encode(x)) == x. Integer codecs (Delta, FrameOfReference, ZigZag) verify value identity incl. the wrap-around cases where the internal subtraction/shift overflows; AlpRd is checked bit-exact (full IEEE-754 content, ±0 canonicalized to match the ALP family). ~100 cases per codec/width.
