- POST /pi/upstreams/{id}/models/refresh calls the provider's model list
endpoint (OpenAI-shaped /models, Anthropic /v1/models, Google
/v1beta/models, OpenRouter /api/v1/models; Radius via pi-ai refresh),
normalizes {id, displayName, contextWindow, supportsVision,
supportsTools, pricing} and stores it in pi_upstream.models (0044)
- GET .../models returns {source, fetchedAt, models[]}: remote merged
with the static catalog (remote first); failures (401/network/
unsupported) fall back to static with a one-line error
- POST /pi/models/probe for trying credentials before creating
- wizard and edit drawer: fetch button, searchable dropdown with
vision/tool tags, manual id, source line; default upstream needs a model
- tests: mock /models, 401, network failure; smoke step; runbook
