Problem
CPU-heavy translated PolkaVM guests paid an indirect tail-dispatch every 16 instructions. Halo campaign execution saturated the PVM worker while the main and GPU workers remained mostly idle.
Change
Gas accounting, block targets, hostcall resumption, trap PCs, and partition boundaries are unchanged.
Verification
cargo test -p polkavm-wasm-compiler: 18 passedThe performance run used local retail map bytes only; no retail data is included in the repository, logs, or artifacts.
