If I didn't see it, it didn't happen.

Here we are without the strap.

R302.11.2 Fireblocking integrity.

The integrity of all fireblocks shall be maintained.

R602.6.1 Drilling and notching of top plate. When piping or ductwork is placed in or partly in an exterior wall or interior load-bearing wall, necessitating cutting, drilling or notching of the top plate by more than 50 percent of its width, a galvanized metal tie not less than 0.054 inch thick (1.37 mm) (16 ga) and 11/2 inches (38 mm) wide shall be fastened across and to the plate at each side of the opening with not less than eight 10d (0.148 inch diameter) having a minimum length of 11/2 inches (38 mm) at each side or equivalent. The metal tie must extend a minimum of 6 inches past the opening. See Figure R602.6.1.

Exception: When the entire side of the wall with the notch or cut is covered by wood structural panel sheathing.

I write a correction that says,"Install a ST62? strap across the damage with 10 #10 1.5" long nails or equivalent on each side".  How they get that wrong dumbfounds me.
