What Happens If a Miner Submits a Share That Meets the Network Difficulty but Not the Pool’s Target Difficulty?
This scenario is highly unlikely because the network difficulty is vastly higher than the pool's target difficulty for shares. If it were to happen, the share would be rejected by the pool's server because it does not meet the minimum required proof-of-work set by the pool's target.
A valid block solution (which meets network difficulty) is always accepted by the pool as a super-valid share.
