I‘m a big fan of original engineering Test Reports, preferably from NASA or one of its first tier sub-contractors, rather than second hand info from watch sites. Qualification testing for intra-vehicle, low earth orbit (before the Van Allen belts) application might not be as stringent as EVA or longer-range missions. Alternatively NASA might have simply performed a FMEA and determined them to be not hazardous to flight, therefore permissible.
