Using the micrometer glasses I found in an attic ...  ... and my advanced photometric dimensional analysis procedures (hold my thumb up to the photo) I would tend to agree with Bill that it might be 3/8 OSB heathing panels. Around my neck of the woods that wouldn't fly even with edge clips.
In the real world I would write up the defect as sagging heathing, recommend repair by a contractor (errr ... I mean detailed structural analysis by an engineer, and sealed repair plans ... lol), and call it a day and go get a pint ...

Green is usually 3/8 and blue is 7/16. At least around here at the Big Orange 
I've got various OSB scraps of differing ages in my workshop. Some have red ends, some yellow, and some a simply delightful shade of turquoise. All of it is 7/16". So I'm not sure I could rely on color.
Obviously the biggest issue is not the missing H-clips but the missing S-key from Gerry's keyboard.

Gerry, I am glad to see you still have your sense of humor, as you noticed the typo and decided to leave it just for kicks. Who said learning cant be fun ...
