Save and load

to_bytes() serialises one fitted revision and from_bytes() restores it after schema and integrity checks. Load artifacts only from trusted sources. A restored model carries no training frame or machine timing, so the reading methods need X_train= and diagnose() says the timing is absent.

to_bytes	Serialize one fitted revision; load artifacts only from trusted sources.
from_bytes	Restore a trusted fitted artifact after schema and integrity checks.
