The Vendor-Outage Drill — Build a Second-AI Fallback and Prove It Actually Catches You

Your business quietly started depending on one AI vendor the way it depends on electricity — so what actually happens on the morning that vendor is down, rate-limits your account, or ships an API change you never read about?

This project replaces the hopeful answer ("I suppose we'd switch to something else") with a second path you have deliberately taken offline and watched engage, and it is honest about the two things nobody mentions in the architecture diagram — keeping two integrations alive is real, permanent work, and a fallback that produces an answer is not the same as a fallback that produces an answer you would let a customer see.

What you'll do

A provider-agnostic router sitting in front of your existing AI automation — a circuit breaker that can tell a two-second rate limit apart from a genuine outage, a second vendor from a different company answering behind the identical output contract, a written degraded-mode policy naming which work fails over and which work queues for a human instead, an append-only failover ledger, and a repeatable fault-injection drill that takes the primary offline on purpose and proves the fallback both engages within seconds and clears a quality floor you measured in advance — then hands the traffic back when the primary returns.
