Plumber cannot figure out how to vent fixtures due to toilet and shower being on opposite wall from stack, with a shared closet wall that allows 2-inch vents but horizontal run below flood rim is required.

No clear code-compliant venting solution without horizontal run below flood rim; existing plumbing knowledge or forums not providing actionable guidance.
