<p>Last month, I woke up to a Slack message from our most senior
engineer: “Did something change? The agent is rewriting entire files
again.”</p>
<p>I checked the logs. Same prompts. Same codebase. Same agent config.
But the model underneath had silently updated — and our carefully-tuned
workflows broke in ways no benchmark would ever catch.</p>
<p>Our CI failure rate doubled in three days. Nobody connected it to the
model update because there was no announcement, no changelog, no version
bump. Just… different behavior.</p>
