API Version Sunset Breaks Silent Long-Tail Consumers

Your team sunset Orders API v1 on schedule. The consumer registry says every known integration migrated to v2 months ago — and it's right, as far as it goes. But 5xx errors and order-creation failures are climbing, and the support ticket queue is filling up with callers nobody has ever heard of. A long tail of internal consumers nobody tracked is still calling v1. Do you extend the deadline, stand up an emergency compatibility shim, or force the cutover through and hope the long tail sorts itself out?
