Module canonical 

canonical — canonical-serialization.md reference implementation.

Three primitives:

• py_float_repr(n) : CPython repr(float) byte-identical decimal.
• canonical_value(v) : key identity (top-level keys sorted only).
• canonical_json(v) : fingerprint (all levels key-sorted; arrays keep order).

Object-key sort is Unicode code-point order across all languages. Rust str Ord is UTF-8 byte order which equals code-point order, so sort() on &str/String is the normative comparator (verified by the astral vector).

Functions

canonical_json

Fingerprint canonical serialization: all object levels code-point key-sorted; arrays keep order.

canonical_value

Key-identity canonical serialization: only the top-level object’s keys are code-point sorted; nested values keep insertion order.

py_float_repr

Render f exactly as CPython repr(float) / json.dumps(float) would. Finite floats only; NaN/±Inf return a Failure.
