The rewrite auth_validN_eq was not performed in the hypothesis. It used to work in 8.5 because of magic.

Also, use explicit unfolding lemmas for auth_valid and auth_validN. The `Arguments valid _ _ !_ /` hack did not really work when one has to deal with the valid instance of the cmra, which underneath also includes a `cmra_valid`. Declaring a similar Arguments for `cmra_valid` is a bad idea, it will also end up unfold stuff for the exclusive and option CMRA.

This allows us to factor out properties about connectives that commute with the big operators.

This requirement was useful in Iris 2.0: in order to ensure that ownership of the physical state was timeless, we required the ghost CMRA to have a timeless unit. To avoid having additional type class parameters, or having to extend the algebraic hierarchy, we required the units of any CMRA to be timeless. In Iris 3.0, this issue no longer applies: ownership of the physical state is ghost ownership in the global CMRA, whose unit is always timeless. Thanks to Jeehoon Kang for spotting this unnecessary requirement.

This is more consistent with the definition of the extension order, which is also defined in terms of an existential.

This is to avoid confusion with ghost_ownership.own.

be the same as
↔ . This is a fairly intrusive change, but at least makes notations more consistent, and often shorter because fewer parentheses are needed. Note that viewshifts already had the same precedence as →.

Based on an idea and WIP commits of JH. Jourdan: the core of a CMRA A is now a partial function A → option A. TODO: define sum CMRA TODO: remove one shot CMRA and define it in terms of sum

 Make the carrier argument of the constructors for the canonical structures cofeT and cmraT explicit. This way we make sure the carrier is properly exposed, instead of some alias of the carrier.  Make derived constructions (such as discreteC and discreteR) notations instead of definitions. This is yet again to make sure that the carrier is properly exposed.  Turn DRA into a canonical structure (it used to be a type class). This fixes some issues, notably it fixes some broken rewrites in algebra/sts and it makes canonical structures work properly with dec_agree.

The only drawback is that we have to restrict iprod to finite types, but that is fine.

So, only use the type class for contractive functors.

Ralf Jung authored
Add both nonexpansive and contractive functors, and bundle them for the general Iris instance as well as the global functor construction This allows us to move the \later in the userdefined functor to any place we want. In particular, we can now have "\later (iProp > iProp)" in the ghost CMRA.
