light-compressible
Compressible account lifecycle for accounts with sponsored rent-exemption. The program pays the rent exemption for the account. Transaction fee payers bump a virtual rent balance when writing to the account, which keeps the account "hot". "Cold" accounts virtual rent balance below threshold (eg 24h without write bump) get auto-compressed. The cold account's state is cryptographically preserved on the Solana ledger. Users can load a cold account into hot state in-flight when using the account again.
