There was a problem hiding this comment.
Nice catch.
assert data.target.epoch in (get_previous_epoch(state), get_current_epoch(state))
assert data.slot + MIN_ATTESTATION_INCLUSION_DELAY <= state.slot <= data.slot + SLOTS_PER_EPOCH
The above indeed left just that little bit of flexibility that the epoch of data.slot can be 1 epoch off from target epoch.
