If you really care about your job and plan to continue working there, i.e. making it a career, then de-escalate this situation as soon as possible. Don’t worry about who is right, just appologize and move on. Try to set things right with your boss; you will always screw up some day and don’t need one or two strikes against you.
My situation was I knew where all the bodies were burried, but I never played that card, just kept it in reserve (never had to use it) until I was able to get my time in and leave. Best thing I ever did was to get my time in (toward retirement), then leave the first day possible.
“Best thing I ever did was to get my time in (toward retirement), then leave the first day possible.”
“Amen!” to that.
Before PC worked its way into every facet of the workplace, going to work was fun for me. Then slowly it turned up-side down and became grueling torture.
