Hi, all,

I support adoption of the invariants draft.

Noted, though the point of declaring something an invariant is to say "the meaning of this part of the wire image, expressed as a bit offset, will never change". You can add constraints to the invariants, but if you think you might remove a constraint, then it's not an invariant by definition.

Cheers,

Brian
