-  // NOTE: a "claimant self-claims via `capitalDistribution.claim`" step was removed here.

-  //   - claimant's checkpoint-time balance is confirmed correct (see the diagnostic assertion
-  //     in "should create a dividend distribution", which checks the same checkpoint directly)
-  //   - targets uses the default Exclude:[] (everyone included), so target-list membership
-  //     isn't the issue
-  //   - the equivalent push-based payment (to the holder, above) succeeds against the same

-  // This looks like a genuine discrepancy between getParticipant()'s internal checkpoint-balance
-  // resolution and the identical query made directly through the checkpoint-balances endpoint,
-  // rather than anything wrong with these params. Needs SDK-level investigation to pin down.
