Would this be a Fairing? (and therefore Rules-illegal)

Hi all,
I have been thinking of different containers to make (3-D printer) to hold my puncture-repair kit instead of the saddlebag I have.
I know that fairings are competition-rules illegal, but does “fairings” cover items on the leading edge of your frame/bike or does it also cover items on the rear-side of these posts/tubes?
example: A case which sites in the inner angle of the top-tube/head-tube/down-tube, which matches the head-tube width and trails off so that the combined head-tube+case = an aero-foil shape like is done with carbon on them fancy bikes (P5/Shiv).

I see the Trek SC 9 has a parts pod behind the seat tube, so wanted to see if the this is allowed then are others.

If this has been already discussed, anyone got the link as I must be searching for the wrong term in this forum.

Thanks.

If I have been informed correctly the added element has to serve a useful purpose other than just being a fairing. i.e. its not a fairing, its just a very aerodymanic repair kit holder.

I believe Trimble did it a quarter century ago, and it was legal at that time for triathlons

Nice, thanks.
I’m always worried that I am missing some rule somewhere which contradicts the main rules Doc.

Have a look at mine - totally ok

Also a reference here about USAT rules requiring a carrier to fit through a 8" x 10" cutout:

With mine, I emailed the race director (IM Western Australia) to get their approval prior to the race. If in doubt, contact a race director or someone at USAT and see if you can get an answer.
