But then you would have something that is prior art.
It isn't prior art just because you did it.
It isn't even prior art if you can prove you did it.
It is only prior art if you published it. Or you can prove in some
other way that the idea was well known among those skilled in the art,
or obvious to them.

That is completely incorrect in the US. Publication is NEVER required
with respect to establishing prior art. At least two things
automatically support "prior art" status:
1) Valid documentation (but not necessarily publication) of the prior
art. This usually means something like a lab notebook entry, witnessed
by others.
2) Shipping a product that contains the prior art. No notification or
publication is required.
There are undoubtedly other means of establishing prior art that do not
require "publication". In the US, establishing prior art is a matter for
courts and lawsuits, so YMMV.
