Function assemble_resident

    pages: &[ContextPage],
    mandatory_ids: &[String],
    env: &DependencyEnv,

) -> Result<ResidentOutcome>

Assemble the resident context per Definition 6.

instruction_tokens is c(I_t) for the compiled programs; frame_tokens is the synopsis frame bound q. Every candidate offered for selection must already respect q; pages whose dependency fails are excluded before selection.
