Type Alias PastCodePruning

PastCodePruning: StorageDescriptor<[], FixedSizeArray<2, number>, false>

Which paras have past code that needs pruning and the relay-chain block at which the code was replaced. Note that this is the actual height of the included block, not the expected height at which the code upgrade would be applied, although they may be equal. This is to ensure the entire acceptance period is covered, not an offset acceptance period starting from the time at which the parachain perceives a code upgrade as having occurred. Multiple entries for a single para are permitted. Ordered ascending by block number.
