Watch it decide.

This runs the real classifier and the real selector — filters, ranking, stickiness — and stops before dispatch. It is the same /v1/explain endpoint you can call yourself, and it costs nothing to run, which is why it needs no key.

The request

critical

critical marks value-bearing work and pins residency to in-infra, whatever the concept or the ranking would prefer.

The decision will appear here.

Call it yourself

curl https://api.fiferouter.com/v1/explain \
  -H 'content-type: application/json' \
  -d '{"text":"can this retry double-charge the customer?","critical":true}'

It accepts an OpenAI-shaped body too, so the same payload can go to /v1/explain and /v1/chat/completions and be compared.
