I think options 3 and 4 are somewhat confusing between them. Basically it's better to specify whether we are speaking of the overlay (the script as it appears) or of the underlay (that which the observed script is utilized to convey).
For example, for the "hoax theory": the overlay is not a natural language, and there is no underlay at all.
