Note that olcott defines 'verified fact' as 'proven fact', but he is unable to show the proof. So, it must be read as 'my belief'.

A "proven fact" without a proof is not worse than a "verified fact"

It is self-evidently true to anyone having sufficient knowledge
of the semantics of the C programming language.
 No, it is not. I would know if it were.
 
If you do not understand that a single valid counter-example
would refute my claim then you don't know enough about proofs.
If you do not understand that a single valid counter-example is
the only correct refutation of my claim then you don't know enough
about proofs.
