How are creative looks carried from set to post under ACES (Look Transforms, AMF, CDL plus LUT), and what do the ACES docs say is not portable?

ACES Look Transforms are whole-image ACES-to-ACES transforms carried as ordered Transform IDs in the ACES Metadata File; CDL values chosen under an LMT are invalid without it; non-ACES looks/LUTs are hard to translate (rebuild them in ACES); archive original ACES files plus grading data, the ordered LMTs and the ODT. 'Well-designed LMTs are interchangeable' is a stated design aim, not a test result.
