pub fn reference_json() -> StringExpand description
Serializes the canonical reference.json bytes.
Deterministic: sections sorted by name, two-space indentation, a
single trailing newline — byte-identical across regenerations on
the same platform. The f64 oracle vector’s bits are
platform-libm-shaped by design; cross-platform verification is
semantic (verify_str), never a byte compare of the whole file.
§Panics
Panics if a committed fixture is unreadable or fails to decode
(see digest_of).
