You should put the meaning of the abbreviation C.I.H. at the first mention. It's bothersome reading the first few sentences, reading C.I.H. and not knowing what it means. Also Object Class Formatting and Rating Module.
Stupid nitpick, but why is the picture so low? Also, I do like the idea of using a .gif file, but this one seems to a bit short for the intended purpose.
"In 1915/██/██ researcher ████ exposed their small dog to RPC-028-1 in an experiment to see if the anomalous properties work on other sufficiently complex lifeforms. The goal is to regenerate its lost left hind leg, due to abuse from a prior owner. The following experiment log has been created using a nearby camera system. This experiment yielded the first RPC-028-2.]"
The above should be prefixed by "Addendum 2"
Also the experiement should be formatted to have a forword and maybe use
this character ">" plus a space followed by text to put the log into a box like this. Most addendums do this. Also a space between each line would help readability tons.
Aside from those little formating quips I love this aritcle 100%. I like how you countered the healing powers with the mutation of non-humans. Really well thought out. +1
EDIT: Also the part about it potentially existing in more dimenstion than 3 was really cool and an interesting hypothesis.
Now that’s a delightful variety and creativity in devising a battery of logs and tests. Fun, fun, fun.
Such is life in the Soviet Union
there are many mistakes in the RPC-028 designation, there is also a mistake in the test log timestamp
