Summary
Gossipsub message validation had double-penalization paths: inner validation functions called
penalizePeerdirectly, and the outervalidateReceivedMessagewrapper could penalize again on errors. Attestation cap exceeded was also inconsistently handled (ignored instead of rejected like proposals).Approach
Centralized all gossipsub penalization into
validateReceivedMessageby adding aseverityfield to theRejectvariant ofReceivedMessageValidationResult. Inner functions now return severity instead of callingpenalizePeerdirectly. AddedtryDeserializehelper for graceful deserialization failure handling.Changes
validateReceivedMessage, removed directpenalizePeercalls fromhandleGossipedTx,validateAndStoreBlockProposal,validateAndStoreCheckpointProposal, andvalidateAndStoreCheckpointAttestation. Changed attestation cap exceeded fromIgnoretoRejectwithHighToleranceError.Fixes A-705
