Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Evidence

Proto key rejection (search for "__proto__" near "constructor" near "prototype")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
