"""Focused tests for Upstage Solar first-class provider wiring.

Regression guard for the bug where `hermes model` saved `provider: upstage`
correctly but, on re-entry, showed a different provider as active. Root cause:
`hermes_cli/providers.py` (the resolver behind `resolve_provider_full`) had no
`upstage` overlay, so `resolve_provider_full("upstage")` returned None, the
config provider was discarded, and resolution fell through to env auto-detect.
