The 8 'invisible' open beads were correctly filtered by br claim due to
unclosed blockers in a legitimate dependency chain.
Root blocker: tb-1me (in_progress, updated 12min ago, within 30min TTL)
- Directly blocks: tb-163k, tb-2ir, tb-2lh, tb-62m
- Indirectly blocks chain: tb-3iu → tb-5wj → tb-23i → tb-5n9
The claim SQL filters out beads with unclosed blockers (claim.rs lines 317-322).
This is correct behavior, not a configuration bug.
All blocked beads have 'split-child' label but the blocker filter is what
excludes them from claim eligibility, not the label itself.
Bead-Id: tb-67rg
