… building During re-execution (validation/proving), the public processor must process the exact txs from the proposal. Pre-processing skip checks for estimated blob fields and gas limits are now gated behind a new `isBuildingProposal` flag on PublicProcessorLimits, which is only set by the sequencer.

Summary
Backport of #20974 to v4.
The checkpoint builder now tracks remaining L2 gas, DA gas, and blob fields in a checkpoint while building each block, and forwards them to the public processor. This means that a proposer will not propose blocks that overall exceed checkpoint limits, and validators will properly reject them.
