Root cause for the courier outage reported earlier (feedback cms69tko40004l7049v5g2ybc): the Uber Direct account is DISABLED. Direct call to POST /v1/customers/{id}/delivery_quotes returns 400 invalid_params with metadata.param_details = "This account has been disabled. Please reach out to directbilling-group@uber.com to resolve". The app maps this to the misleading no-courier-available 422. Action needed: contact directbilling-group@uber.com to re-enable the account. Also consider surfacing Uber metadata.param_details in the quote error log in apps/stable-pizza/lib/uber-direct.ts (quoteDelivery only logs json.message).
