All specs rebasing to Hegotá: execution-specs, engine-apis completed; CL spec updates pending
The team decided to rebase all technical specifications, including execution-specs and engine-apis, to the Hegotá upgrade base.
New 12-second attester cutoff deadline needed to prevent split view during equivocations
A decision was made to introduce a 12-second attester cutoff deadline to address network split view issues occurring during equivocations.
8-second deadline to be removed as implementation-dependent example
The 8-second deadline will be removed from the specification because it was considered an implementation-dependent example rather than a core requirement.
