No advice just condolences.
Good inspectors level the playing field and promote safe installations.
Multi-hat, everything is ok because they don't know the Code, guys will get someone hurt or property damaged.
Remember the inspector generally has no liability for missing things, although some sucessful law suits have been filed.
You as the contractor will be held responsible. You might want to let the GC know that he too can be exposing himself to future legal action if he starts letting bad work get approved.
