A Hermes plugin that routes each turn to the cheapest model that is good enough for it — and can escalate the hard turns to a premium rung — with a strict fail-open contract: if anything goes wrong, the request proceeds byte-identical. Ships in shadow mode: it observes and logs decisions until you deliberately flip it to live.
