Had a similar failure on a rear hub. Not sure if I rode it in that condition but I scrapped it as soon as I saw it.

I have a Campy NR hub that my buffing wheel yanked out of my hand and spit to the pavement. Slight hairline crack in the flange. It’s so shiny and pretty that I want to believe it will work just fine. Common sense eventually takes hold and tells me to relegate it to table art.
