The --builder flag had .requires("execution-endpoint") which prevents
using MEV-boost on nodes running with --proof-engine-endpoint only
(el_type: None in kurtosis). Since the proof engine serves as an
alternative execution path, --builder should be usable with either
--execution-endpoint or --proof-engine-endpoint.

Issue Addressed
Running lighthouse with
--proof-engine-endpoint(EIP-8025, no EL) and--builder(MEV-boost) fails because--builderhas.requires("execution-endpoint")in its clap definition.This breaks the kurtosis devnet config where a participant has
el_type: Nonebut still needs MEV-boost for block building via zkboost proofs.Proposed Changes
Remove the
.requires("execution-endpoint")constraint from--builder. Since--proof-engine-endpointserves as an alternative execution path,--buildershould be usable with either--execution-endpointor--proof-engine-endpoint.Additional Info
Error when running with
el_type: None+ MEV enabled:
