One small interoperability issue in ur-tones: https://github.com/ndssigner/ur-tones/blob/4a3c9fa990b8246a4e91b2c4773b072f4b31acea/SPEC.md#4-pin-for-seeds says receivers accept any PIN length, but https://github.com/ndssigner/ur-tones/blob/4a3c9fa990b8246a4e91b2c4773b072f4b31acea/c/ur_tones.c#L163-L174 rejects more than 64 characters. The Python and JavaScript normalizers have no matching length limit, so a long PIN accepted by one implementation cannot be used by the C receiver.
Could the spec define a shared maximum, with consistent validation and 64/65-character boundary tests across implementations? I checked the C behavior from source, not a compiled run. The existing draft/testnet warnings are helpful context; this is a narrow compatibility observation, not an audit.
