Backports the PXE-only portion of #22679 to
v4-next.The full fix in #22679 spans barretenberg world-state, the aztec-node and PXE; only the PXE refactor is portable to
v4-nextwithout dragging the C++ / world-state changes.What this changes
In
yarn-project/pxe/src/pxe.ts, capture the anchor header once perproveTx/simulateTx/profileTx(right afterblockStateSynchronizer.sync()) and thread it through to both#executePrivateand#prove, instead of re-readinganchorBlockStoreindependently inside each call.This is a defensive refactor — the anchor cannot drift today because both callees live inside the same job-queue slot — but it makes the invariant explicit and type-checked going forward.
What this does not include from #22679
WorldStateRevision::LATESTsentinel andis_historical()migration (barretenberg/cpp/src/barretenberg/world_state/*,avm_fuzzer/.../dbs.cpp)yarn-project/stdlib/src/world-state/world_state_revision.tsandyarn-project/world-state/src/native/native_world_state.tsAztecNodeService.getWorldStateinitial-header path change inyarn-project/aztec-node/src/aztec-node/server.ts(+ test)These are intentionally omitted per the request to backport only the PXE changes.
Notes
pxe.tsapplied cleanly at the exact line numbers — no conflict resolution needed.BlockHeaderwas already imported inpxe.tsonv4-next.#) methods are withinpxe.tsand are updated consistently.Original PR: #22679
