Capacity, not commitment

PoF CREBs reflect available balance at the moment of the institutional data pull. Balances may change. JIL does not guarantee that funds remain available, will be wired, will clear, or will be applied toward any specific transaction.

Counterparties relying on a PoF CREB should treat it as evidence of capacity at point in time, not as a payment commitment. JIL is not a bank, payment processor, fiduciary, or escrow agent.

What's in the CREB

Subject of verdict (buyer identity + offer context)
Available balance (signed total across linked institutions)
Coverage ratio vs. offer amount
Institution-level metadata: institution name, account-type class, last-pull timestamp

30-day CREB reuse window

Talk to integration
