Business Preview parity

Hava Business Preview uses the same read-only live-connection executor and sealed credential vault as a published Hava deployment. Authenticated API credentials remain server-only.

Expected behavior

If Preview uses a live connection successfully, the answer includes live-source provenance. If a connection fails, Hava reports the tool failure rather than silently treating current data as unavailable.

Regression check

For the Intellign test connection, asking “How many Nova Headphones are in stock right now?” should invoke the validated live connection and return the current inventory result, with a Live source label.
