@@ -1422,8 +1422,9 @@ Several providers support OAuth authentication instead of static API keys:
- **Anthropic** (Claude Pro/Max subscription)
- **OpenAI Codex** (ChatGPT Plus/Pro subscription, access to GPT-5.x Codex models)
- **GitHub Copilot** (Copilot subscription)
- **OpenRouter** (OAuth PKCE that mints a user-controlled API key)
Each of these providers carries an `OAuthAuth` on `provider.auth.oauth` with three operations: `login(interaction)` uses the provider-neutral `AuthInteraction.prompt()`/`notify()` protocol and returns a credential, `refresh(credential)` exchanges the refresh token, and `toAuth(credential)` derives request auth (GitHub Copilot's per-account base URL comes from here). Refresh is automatic: `models.getAuth(providerId)` and request paths refresh expired tokens under a credential-store lock, so concurrent requests and processes cannot double-refresh.
Each of these providers carries an `OAuthAuth` on `provider.auth.oauth` with three operations: `login(interaction)` uses the provider-neutral `AuthInteraction.prompt()`/`notify()` protocol and returns a credential, `refresh(credential)` refreshes expiring credentials when applicable, and `toAuth(credential)` derives request auth (GitHub Copilot's per-account base URL comes from here). Refresh is automatic: `models.getAuth(providerId)` and request paths refresh expired tokens under a credential-store lock, so concurrent requests and processes cannot double-refresh. OpenRouter's OAuth flow instead returns a permanent API key, so its refresh operation is a no-op.
