Method

Every model ID seen in the public OpenRouter catalog is recorded once and never deleted. Disappearance means the route was not listed on the day we checked; it is not proof the provider retired the model. providerCreated comes from OpenRouter metadata, not from NordPeek observation. Hand-verified shutdown and deprecation dates from official provider lifecycle pages. The daily workflow never rewrites this file. Anything older than 45 days is flagged for re-check.
