Validators whose proposed blocks were reorg'd out. Detected live from beacon head events.

Reorg history starts from when the watcher first ran. Once a block falls out of fork-choice
(~13 min after finalization), no beacon node retains it — historical orphans before that
point cannot be recovered. Only depth ≥ 1 same-slot reorgs are surfaced for now.
