Aura::slot_duration returns T::Moment with a definition
type Moment: Parameter
+ Default
+ AtLeast32Bit // From<u16> + From<u32>
+ Scale<Self::BlockNumber, Output = Self::Moment>
+ Copy
+ MaxEncodedLen
+ scale_info::StaticTypeInfo;And SlotDuration cannot be built out of it.

There are workarounds - what have you tried?

Couldn't come up with any other way. Ideally, I would expect Aura::slot_duration to return SlotDuration.
As you can see from the type definition, it's not convertible to any numeric primitive, so we have to enforce it in boundary.

It's reasonable to enforce it in the boundary as long as that aligns with the instantiations that are typically used in runtime declarations. Seems like a good solution to me.

Now that integration tests are failing due to this panic, I wonder if it's OK to optionally verify the slot and skip it if the value is not present?

I would guess that it's most likely the case that blocks built in tests don't contain the pre-runtime digest which sets the slot in pallet_aura and that they need to.

What happens here if the collator isn't up to date with the latest relay block? I think a "slot number mismatch" would occur.
Right now it seems that collation is still triggered by new incoming relay blocks, so the scenario I described won't occur. But my understanding is that we will want to unteather these.

I believe the state proof comes from the relay parent the para is building on top of.

That's right - the parachain has no information about what the latest relay-parent is, other than what the collator gives it. But validators will only accept blocks with recent relay-parents.

Resolves #2588
This PR also removes the
CheckInherentsfunctionality used during Cumulus block execution, as that is now replaced by theConsensusHookinterface ofparachain_system.
