Separate venue rules from account evidence

A funding history can show a published rate without proving that a particular account held an eligible position or received that payment.

RecordWhat to preserveWhy it matters
Venue ruleExact contract, source URL, check date, interval and sign definitionDefaults and adjustments differ by market
Funding eventUTC time, raw rate and field, size, conversion price and event notionalEach settlement may use a different basis
EligibilityPosition at the snapshot and confirmed event statusMissing observations are not proof of zero
Account recordPosted debit or credit, currency, source and reconciliation differenceHistory estimates are not account cash flows

Review each event in order

  1. Freeze the venue and contract-specific rule.
  2. Align event timestamps and rate units in UTC.
  3. Preserve the raw sign before applying the formula.
  4. Check position eligibility and the venue notional basis.
  5. Reconcile modeled amounts to an account record when available.
  6. Keep any unresolved value marked unknown.
