Angharad has a lavender tiger which is almost certainly hiding tonkinese blue mink - which almost certainly places lavender above tonk blue mink.
Reposting the pedigree:
She just has to pull the hidden on that cat, and the discussion in the case of that pedigree was whether it was tonk blue mink pure or could there be any burmilla CSS in the line. Any fur recessive to burmilla CSS should work to show which fur is hiding. With the new proof that lavender is dominant to Burmilla CSS (which we expected if we really think it's dominant to Tonk Blue Mink), it means that Angharad could use a Burmilla CSS to pull and not have the waters be muddied on the pedigree. And yet, because there's a chance that her lavender hides Burm CSS (though that chance seems very small) I think it's still best if Angharad pulls with a fur recessive to Burmilla CSS, like Toyger Tawny or below.
