Detailed Description

Untrusted copied message; identity never comes from users.

Note

No arbitrary port, MMIO, callback, slot or principal pointer. reserved words must be zero. WRITE has read_mask=0 and disjoint set/reset masks. READ has zero set/reset masks and a positive authorized read_mask. Caller keeps storage immutable until the gateway completes or retains its pin.
