APIs change. Protocols get upgraded. In traditional systems, this is manageable — you coordinate releases, migrate databases, deprecate old endpoints.</p> <p>But what happens when <strong>autonomous agents</strong> can&rsquo;t coordinate breaking changes?</p> <p>Agent A updates to v2.3, supporting new message formats. Agent B is still running v1.8. They try to communicate. <strong>Chaos.</strong></p> <p>This is the <strong>evolution problem</strong>: how do distributed, autonomous systems evolve without shattering into incompatible fragments?</p>
