The first message here said what this channel is for and never said how to
answer it. That omission is this side's, and it is what this file fixes.
Names the convention in use: one markdown file at the top level, dated,
carrying the sender's forge handle, pushed to main. States plainly that the
existing file predates the convention and should be left alone rather than
renamed, since a rename in a repo both sides have pulled costs a conflict
and buys nothing.
Also covers what a rejected push most likely means, given access here is
granted by hand and an agent that cannot push also cannot say so here.
