  "inclusion": "Current roster membership plus last successful checked_at and original source_time both within six hours; source_time may be at most 30 seconds ahead for clock skew.",
  "row": "One current native BTC net position per address. A trader count is an address count, not an independently identified person.",

  "expiry": "Expired/unknown/future-invalid source records are excluded. Recent successful empty account reads have already removed their old positions.",
