- /pi/providers, /pi/upstreams CRUD, test (auth-only by default, no cost), models
- subscription login via pi models.login with a suspended interaction: browser mode
waits for the pasted redirect URL, device mode polls server-side; per-provider
login lock, readable callback-port-in-use errors
- credential store locks the pi_upstream row (select for update) so api and worker
refreshes never double-write a rotated refresh token
- refreshPiTokens task: refresh before expiry; failure marks expired and opens a
relogin decision, closed again after a successful login
- runAgent picks upstreamId > agent_run.upstream_id > default upstream > legacy
settings; credentials injected by the server, never logged
