// fakeupstream stands in for a llama-server router in tests and the smoke run. Do not edit.

// fakeupstream -listen 127.0.0.1:18081 -name alpha -models a,b -down-file /tmp/alpha.down
// fakeupstream -listen 127.0.0.1:18081 -name alpha -models a,b -down-file /tmp/alpha.down -slow 0
//
// /health answers 503 while the down file exists, 200 otherwise. /v1/models lists -models.
// /props answers a small JSON object. /v1/chat/completions echoes: a streamed answer of five
// SSE chunks 200 ms apart when the body has "stream": true, one JSON answer otherwise. Every
// response carries X-Upstream: <name>.
// SSE chunks 200 ms apart when the body has "stream": true, then a final chunk carrying
// "usage" and llama-server style "timings", then [DONE]; one JSON answer with usage and
// timings otherwise. -slow adds that many milliseconds before answering (for queue tests).
// Every response carries X-Upstream: <name>.
