I misremembered nothing.
Allow me to refresh your memory.
I've never heard of any form of indoctrination shielding. What I do remember was a reference to studying the human reaper remains from a distance using drones to avoid exposure.
That's not what the blurb says. It does not mention a distance, it does not mention avoidance and it does not mention exposure. It mentions drone-assistance, it mentions direct contact and it mentions risk. You misremembered, simple as that.
The blurb says they study it using drones.
"Drone-assisted" is a very specific choice of words which means, very literally, that the drones are used to assist the subject - in this case the engineers - in carrying out their action - in this case the studying of the Reaper remains. Ergo, the engineers are doing the studying with the assistance of drones, exposing themselves to the risk mentioned in the blurb, which we can safely and easily deduce to be indoctrination - unless you also want to suggest the Reaper brain is armed with conventional weaponry, a suggestion which has zero basis in the blurb. It is very basic reading comprehension we're dealing with here.
The problem is that you are insisting on a more strict definition of "direct" than the context suggests.
The problem is that the context suggests the exact definition of "direct contact" that I quoted earlier because that is literally the only definition that exists for that specific term. For some reason, you don't want it to have that definition.
I find it more likely that "direct" merely refers to the fact that they are studying part of a Reaper rather than something derivative like Collector technology or a device.
Finding something likely means you are not certain about your conclusion. If you are not certain about your conclusion, then you are making an assessment without sufficient evidence to state it as fact. In this case, sufficient evidence would be a dictionary definition of "direct contact" which supports your thesis that such contact can take place through a liaison, and not through physical contact with the object, without any intermediaries or intervening agent to carry out the action by proxy.
Find me such a definition and I will concede that you are right about drones being able to make direct, physical contact with the Reaper brain on behalf of the engineers. You will, however, have to concede that you misremembered the part about avoiding exposure, because the part which weighs the risk of direct contact versus the value of possible insights into Reaper vulnerabilities cannot be interpreted as anything but the engineers exposing themselves to risk through direct contact with the source of the risk, indoctrination. We do know indoctrination works at range, so no physical contact is necessary for there to be direct contact with the tech for the effect to take place.
Now, I would like to leave this word lawyer career you've forced upon me and focus on helping BioWare understand what they're doing wrong and what they need to do to make things right again.
It's flawed because it doesn't have Jojo.
It's flawed because it doesn't have Saitama. He could just punch the Andromeda, thereby forcing the Ark to turn back around and saving us a game of inevitable disappointment.
