[null and void]

The hole as pictured, next to several stamp marks in the metal, possibly indicate it was a documented defect that was repaired.

I don't see stamping, I do see a couple scuffs where the chuck rubbed against the rib that look a little like black QA stamps.

Several false starts and drill bit skipping. Miscreant was either quite drunk/drugged or very nervous, or unable to properly brace in zero g.

Is this damage something that would have survived blastoff? obviously that photo would have to be from inside the ship, and if those are scuff marks, was drilled from inside. Maybe there is an alien virus that is taking over the crew members one by one? Like in that movie “The Thing”. Where the members turn paranoid, etc.

Try enlarging the pic. It’s stampings alright. Also looks like whatever made the hole started from the other side.

The drill user wasn’t anchored well enough to drill and as you suggest skipped the bit ....... gauze and tape ?? Seems a tap and a fine thread machine screw with some loctite may have been a better fix....... buts its allegedly in the soyuz versus the ISS. Guess it’ll be studied ...... our serious wild ass guess (SWAG) contribution aside.
