RPC Authority

The idea that the Authority desperately is trying to keep someone alive as a means of containment is interesting, however I do not think it was executed to its potential here. In its current state, it is little more than the concept. I think this can be attributed to the consequences of the death being very simple.

You know how when kids play superheros they just make up rules that'll make them win? "You shot me but I have a invisible force field that can't be turned off!". That kind of thing. The clay golem feels like a bit of that. I get that you need to make it feel extremely threatening, but having it be so… overpowered in this boring way makes the idea feel underdeveloped. The text literally reads "exert any amount of energy necessary to breach containment." which is very goofy writing. I don't know if you get just how powerful that is. Also, if it can exert any force necessary, why does it need to transform to escape the form instead of just, waking forwards?

The discovery log portrays the Authority as fairly serendipitous. What proof was there that the guy isn't just some schizo with a cube? Nothing anomalous was seen before containment, and all the "discovery" actually occurred after acquirement. I think you should make the discovery log more meaty, this will however be harder to write as an accident outside facility walls will have more variables you'll need to account for, and no, "cleanup and amnestization" doesn't account for nor seal all the damage an aggressive creature with unlimited energy can cause.

Usually, I'm not a fan of incident or experiment logs that just repeat the description. but yours does a good job at exemplifying the entity. However, as a result of the bland ability, they are also numb.

Also, If you're going to rethink the effect, it doesn't have to be exclusively destructive. What more ways of "spitting in the eye of creation" are there?

Finally, and a bit of a nitpick, the first description doesn't feature anything anomalous. Felt odd having that be the first thing we get to know. Perhaps add a "death results in activation of RPC-XXX-2."?

The containment room must include a medical bed, with physical restraints, and all necessary medical and auxiliary equipment required to sustain RPC-XXX-1's life.

"The containment room must include a medical bed with physical restraints, and all medical and auxiliary equipment required to sustain RPC-XXX-1's life."

Any method or substance deemed necessary to keep RPC-XXX-1 alive must be procured and administered immediately without delay.

"Any treatment required to prevent death is to be administered immediately."

Access to RPC-XXX-1's containment area is restricted to Level 3 personnel and above, or authorized medical personnel only.

This sentence sound weird to me, and I couldn't find a way to preserve you're intent. I'd suggest using the stuff in the security clearance tab to cut some unnecessary wording. Moreover, "medical personnel" in this case would just be specialized containment employees.
