On the image caption, peeking, not peaking.
The containment protocols are nicely detailed. However, you could add to this a site. About the time period mentioned, you should specify local time or what time zone is to be used as reference.
Every night from 7:30 PM - 6:30 AM, RPC-993 must be monitored cautiously for any RPC-993-2 instances; monitoring must continue until all instances disappear.
report to the site manager immediately.
Even more reason to add a Site to the containment protocols.
D-class personnel designated for testing with RPC-993 must be filed under careful registration by personnel of Clearance level-2 and above
higher "prestige"
I believe this "prestige" calls for a footnote clarifying what this means.
The description could use some rewording:
RPC-993 designates both the black stain beneath, and anomalies generated from a twin-size memory foam mattress bed with no other apparent anomalous property except for it's hinted "invulnerability", and the anomalous "shadow" underneath it.
Every night from 20:00-00:00 to 03:00-06:00
You have to be consistent, back on the containment protocols you cited 7:00 PM, not 19:00. Settle either on the 24 hour military format or 12 hour format. But no using them interchangeably, it's inconsistent and looks sloppy.
recordings of RPC-993-01 results in an empty record.
[RPC-993-2 unit 05-15 has been removed from the list as directed by Director M█████]
This reads redundant, change the "directed" for "ordered", "requested" or something similar.
The collapsibles do add a lot to this article, I in particular am quite horrified by the dolls and the implications with the old man and the liquids. Good job on it, the collapsible interview could be listed as an Addendum.
Class B amnestics have been given to the K██████ couple along with false memories.
