Instance Selector

The instance selector in the top bar picks which ERP.net connection your messages, tools, and apps run against. It mirrors the Agent Selector almost exactly — same persistence rules, same fresh-start vs in-conversation distinction.

What you see

• The active connection's display name.
• A coloured status dot — Active (green), Expired (gray), or Disconnected (muted). See Instance Connections › Status indicators.
• A 🏠 badge if the connection is your home connection.
• A dropdown with all your connections, an Add new entry, and a Buy AI Credits entry on instances you administer.

How the selection is remembered

The instance selection is part of the same tab selection that holds your agent and reasoning level:

• Per browser tab — each tab can be pointed at a different instance.
• Per profile — your profile stores a default. A new tab opens on whatever you last picked.
• First load of a new tab — Operator reads the profile default into the tab's session storage on first mount.

When the picker writes to the profile

• Fresh-start change — switching instance from the Home screen (or pressing New and then switching) updates both the tab and the profile default. New tabs will inherit it.
• In-conversation change — not allowed. Inside an existing conversation the instance selector is read-only and shows the connection that conversation was bound to. Pressing New returns you to your tab's instance.

This guarantees that browsing an old conversation against a different instance never silently rewires your defaults.

OAuth, reconnects, token refresh

When a connection expires or you go through the ERP.net sign-in flow again, the result is written only to the current tab — not to your profile. Your home instance and your default selection are preserved.

Adding and managing connections

The dropdown's Add new entry opens the same dialog as the My Connections page. For everything else — renaming, setting the home connection, AI credit budgets, deleting — see Instance Connections.
