A closed wallet's NWC payments fit iOS's ten-second wake: a paid send is never marked for revocation by a second wake, lookups report outgoing sends and finish them, and pushes no longer run side by side

PullCap's night of 2026-10-24: every wake's diary stopped 8-12 s after its push (iOS stops the worker there, not at 30 s). Two wakes two seconds apart both drove one send; the second's InitiateLightningPayment was refused ("state: ln-spent") and the paid send went to 'revoking', where every later wake spent its whole budget on it, so no request was answered after midnight.

- manager: an initiate refused as ln-spent follows the payment ('initiated'); a send in 'revoking' asks the ASP first (paid: settle; in flight before expiry: back to waiting; not found: revoke)
- worker: 9 s budget on Apple endpoints (27 s elsewhere) for answers, earlier sends and renewals; every ASP step held to it
- lookup_invoice asks every copy of the connection and drives an outgoing send in flight, answering settled with the preimage
- a lease in the worker's IndexedDB store serialises pushes (the Web Lock didn't); diary notes a missing Web Locks API
- the reply and the mirror save run together; stuck sends are finished before a new payment only when they hold its coins
