Safety Properties in Distributed Systems
This day launches phase-4 by defining safety as the absence of invalid global states, establishing the correctness lens required for all later fault-tolerance and AI-serving work. It matters because every production distributed component the learner ships must first satisfy an explicit safety invariant before liveness or performance can be considered.
