Aaron's substantive refinement: row-level CASPaxos/CASRaft tier between optimistic CAS and BFT prevents jumping from local-CAS-too-weak to BFT-too-heavy. Amara's deeper reframe: 'trust-gradient COORDINATION POLICY, not consensus hierarchy' — because some tiers (local DBSP retraction = algebra; Orleans grain ordering = actor lifecycle) aren't consensus at all. Routing-gradient-not-mandatory-staircase: pick the weakest mechanism that preserves the needed authority boundary; facts can jump tiers.
