Expand description

Cooperative cancellation for a logical scope of EVM simulations.

The signal itself is provider-free and is observed at EVM instruction boundaries. It cannot interrupt a database callback or precompile that is already executing; callers that require a wholly provider-free cancellation path must construct their overlays without an external database.
