LGTM, a few comments, mostly asking for extra references.

**Evidence expiration:** Additionally, because we cannot infer the actual time of the evidence (i.e., the timestamp of the evidence cannot be trusted), we do not consider _evidence expiration_ and hence old evidence is never ignored (e.g., the provider would act on 3 year-old evidence of equivocation on a consumer).
Additionally, we do not need to store equivocation evidence to avoid slashing a validator more than once, because we [do not slash](https://github.com/cosmos/cosmos-sdk/blob/v0.47.0/x/evidence/keeper/infraction.go#L94) tombstoned validators and we [tombstone](https://github.com/cosmos/cosmos-sdk/blob/v0.47.0/x/evidence/keeper/infraction.go#L138) a validator when slashed.

We do not act on evidence that was signed by a validator [consensus key](https://tutorials.cosmos.network/tutorials/9-path-to-prod/3-keys.html#what-validator-keys) that is _pruned_ when we receive the evidence. We prune a validator's consensus key if the validator has assigned a new consumer key (using `MsgAssignConsumerKey`) and an unbonding period on the consumer chain has elapsed (see [key assignment ADR](https://github.com/cosmos/interchain-security/blob/main/docs/docs/adrs/adr-001-key-assignment.md)). Note that the provider chain is informed that the unbonding period has elapsed on the consumer when the provider receives a `VSCMaturedPacket` and because of this, if the consumer delays the sending of a `VSCMaturedPacket`, we would delay the pruning of the key as well.

Could you mention here that a malicious consumer chain can not delay sending VSCMaturedPackets forever? (This should hold true due to the VSCTimeout) I know this is mentioned in the ICS protocol, but might be good to have it here too for context

I believe a malicious consumer chain can delay a VSCMaturedPacket forever. If the consumer chain is malicious, it could never write the VSCMaturedPacket packet in its store for the packet to be sent. In my view, the timeout assumption holds if the consumer chain tries to actually send the packet and this is not received on the other end.
