I think you're going to kick yourself.  ".*" ,means zero or more
characters, so matches anything.

It looks like the superfluous "*" is the only thing wrong here.

AFAIK it just means that the rule matched without matching any actual
text for the debug to display.

This looks to be a bug where "negative match" is also displayed if the
matched text is "0", i.e. the number zero rather than a null string.
