Interesting approach.  But I don't know about contexts= or something
like that.  It means there are two passes through the regex.

Also, I don't know about contexts either - if the series was requested
to rebase, every lab that can re-test probably should since the results
aren't going to be valid from the old tests.

Just back from PTO - actually, I don't think we need to adjust the
label, but rather the description.  That would allow the mechanism that
overwrites the existing test to keep the "checks" page tidy, but also
making the retest information clear.  WDYT?

That would be great!
