QUADPublic Accountability
Start with account class before amount. Same number, different law.
These are public account boundaries. They are not private signer maps and not live custody proofs.
Use these classes before treating a value as available, owed, blocked, or terminal.
Owed is not paid. Receivable is not spendable until paid and receipted.
Known obligation inside its expected service window.
Approaching payment, refund, service, proof, or settlement window.
Requires action or explicit refusal before stronger claims continue.
Downgrade public claims until payment, receipt, refund, or refusal is visible.
Challenge, evidence, appeal, or support path must own the next state.
Paid, refunded, refused, written off, expired, or terminal with a receipt or status.
These mistakes create the wrong public behavior.
A service wallet can pay bills or gas without becoming reserve proof, Treasury custody, or market depth.
Test funds, staged credits, or faucet-style coordination do not prove user custody, sale access, or future entitlement.
A relayer may move packets or gas, but it does not become market-maker, pricing authority, or admitted-value owner.
A provider can perform accepted work or hold service obligations without controlling chain law.
A receipt proves its bounded event. It does not unlock funds unless the owning surface says so.
The main domain can explain and route. It cannot make a balance live, admitted, settled, or spendable.
