* nwc: enforce per-connection spend budgets + flag-gated incident containmentAdam Soltys2026-08-221-0/+39
Thread the remaining allowance through every spend path (pay_invoice, pay, pay_keysend, internal transfer) as maxTotal, and have debit() assert the spend stays within it after it reloads the invoice and captures the tip — so a delegated NWC credential can no longer exceed its configured budget, and a mutated tip can't slip a small-budget check and drain via the internal path. checkBudget now returns the remaining allowance alongside any error; a blank budget is treated as deliberately unlimited and a positive budget requires a known renewal period. Add operator-controlled containment for a suspected credential disclosure, all gated behind Redis flags with no hardcoded scope: nwc:disabled fail every method closed nwc:credential-cutoff retire connections created before an epoch nwc:quarantined block an individual disclosed connection nwc:guard:dormant-keysend quarantine the first keysend on a long-idle app Fix an ownership check that read the bare pubkey instead of app:<pubkey>, which let an authenticated user overwrite another connection's config, and validate budget/fee/renewal inputs.
