Got the credentials from Yaribay; still in-progress of gate scanning. Ran into a "Suspect Scavenger" orbiting a gate... but was able to scan the gate regardless.
I'm not sure if this applied to just this encounter, as - based on prior experience - I just approached & dealt with the first two orbiting fleets (bribed a TT fleet, blew up a pirate fleet) before even trying to interact with the gate; this time I was navigating to the gate on autopilot and the scavenger was orbiting through a nearby asteroid field (Yma star system's gate), so I didn't notice it until I was right there - and then I clicked on scan the gate anyway just for curiosity and, to my surprise, it worked.
Hegemony Special Task Force (in Aztlan) did properly block scanning the gate... but the fleet weirdly tried to run away from me when I went to talk to them. (Hegemony rep is 61/100, transponder was on, no commission; other Hegemony fleets in-system had the expected reaction of not caring about me one way or the other.) Aside from that unexpected skittishness, that encounter worked as expected.
I do not, unfortunately, have a conveniently timed save file to share.
