Description

Rather than

BriemHand[wght].ttf: com.google.fonts/check/tabular_kerning: FAIL [has-tabular-kerning, has-tabular-kerning, has-tabular-kerning,
has-tabular-kerning, has-tabular-kerning, has-tabular-kerning,
has-tabular-kerning, has-tabular-kerning, has-tabular-kerning,
has-tabular-kerning, has-tabular-kerning, has-tabular-kerning,
has-tabular-kerning, has-tabular-kerning, has-tabular-kerning,
has-tabular-kerning, has-tabular-kerning, has-tabular-kerning,
...

it makes more sense to say:

BriemHand[wght].ttf: com.google.fonts/check/tabular_kerning: FAIL [has-tabular-kerning]
