Question

Yesterday I made a bitcoin transaction between a Wasabi wallet to my Coldcard skeleton wallet in Wasabi. I created a receive address from the Coldcard skeleton wallet and sent Bitcoin from the Wasabi wallet to it. I inadvertently hit send without creating a psbt file and exchanging the micro SD card between my laptop and the Coldcard.  The transaction appears to have gone through as the balance of the bitcoin I sent appears to have moved from the Wasabi wallet to the Coldcard skeleton wallet. I am nervous, however, about whether the bitcoin is truly there. How is it possible that the transaction went through without having signed the file through my coldcard? Sorry if my terminology is imprecise.
