Max you know your stuffNice Iso’s!
In NC the bath tub p-trap must be protected with its own vent before a flushing fixture enters the line. This plumbing code is in place to keep the mass of water from a flushed toilet traveling down stream and syphoning any p-trap dry. If you run a wet vent from the closest lavatory and hit your horizontal tub drain line first, then let your toilet enter the line, it would pass inspection down here.
Check your state codes. (Which could take a while to find the right venting section to read)
Here’s how the NC code reads. (My inspectors phone pictured)
