Interleaved subagent fan-outs were tagged with the first 4 hex chars of the delegation id ([b2ac 3/9]), which is attributable but unreadable. Batches are now numbered in order of appearance per process: [set 1 · 3/9], [set 2 · 1/7]. Desktop /agents already labels groups "Delegation N", so its duplicate hex badge is dropped.
