* initial validator attesthead rewrite based on proposer rewrite * proceed with fetching committees and tree hashing the canonical head at assigned attester slot * complete filling the properties of attestation data and all associated root hashes * add when to attest todo * finish entire attester client logic * tests with mocks checked in * tests passing in client * stubbed out server implementation * fixed build due to old property * regen mocks with new mockgen version * fixed broken tests * complete bazel build fix * address some review comments * deep proto test * tests passing after checking for empty committee and crosslink root * address nishant comments
