What ❔
During VM run in state keeper we save all storage refunds that are returned by oracle. Later in basic witness generation these refunds are reused.
Also,
zk_evmis updated so that it now passes correct timestamps forestimate_refunds_for_writequeries. Correct timestamps are necessary for VM storage oracle to rollbackreturned_refundsWhy ❔
With new VM, pubdata tracer mutates oracle affecting storage refunds. As this tracer is only run in state keeper and not in witness generator we must save refunds from state keeper and use them in wit-gen.
Checklist
