a closed wallet keeps its coins renewed. Three asks from a subscription service builder (PullCap, by DM, 2026-10-16) testing a 1-sat-an-hour pull against a locked phone. (1) "For a monthly subscription a monthly cap would be tighter": a connection's budget now resets every day, week (Monday) or month, in UTC (nwc-budget.js: the window key stamps the spent counter; both the app and the worker count by it), chosen on the form, read on the card ("21,000 a month · 0 spent this month"); the worker now also counts what the APP spent this window (the counter rides the mirror) — it only ever counted its own log before, so a daily budget could be exceeded across the two; get_budget answers used/total/renews_at/renewal_period (NIP-47), in get_info's method list and the 13194 event. (2) "Does V3 reply with an NWC error when a connection is revoked, or just stop answering?" — it stopped: the open app dropped the request, the mirror forgot the key, the device even de-registered it from the push notifier, so a revocation looked exactly like a phone that is off. Now a revoked connection is kept for 30 days (revokedAt; the earlier date wins in a merge): still subscribed, still registered for pushes, still in the mirror flagged, and every request on it — from the app or the worker, in the asker's scheme — is answered UNAUTHORIZED "this connection was revoked"; no capability event for it; after the grace it is forgotten. (3) "If a user is only woken once a month by an NWC request, will V3 renew the coins on its own?" — only for one cycle: the app registers a standing order per coin, but a coin the worker SPENDS voids its order and the change had none until the app next opened, and a renewed coin sat unclaimed until then too. Now every NWC wake, after the answer and inside what is left of the push budget (tendRenewals, sw-nwc.js): claim orders whose round has run — and drive a claim left in flight on, since one takes several round trips and confirmations — then register an order for every coin without one (backstopMargin shared with the app; limited to the output keys the mirror carries; the mirror now also carries the output key a standing order or a claim in flight burned, which was below the window). Standing orders merge by unlock hash when the app returns (mergeScheduled, in mergeArkStates), so it adopts the worker's. tools/ark/bg-renewal-test.js on regtest, end to end: the worker registers from the mirror alone, a worker spend kills the order and the next wake covers the change, the round runs with nobody online and the next wake claims the renewed coin — and covers it in the same wake — then the app merges it all (fresh coin, right balance, the order adopted, not busy, one history row). tools/nwc-budget-test.js (windows, renews_at, counting with the worker's unabsorbed spends); nwc-sw-test.js (monthly budget over app+worker spends, last month's not counted, get_budget, UNAUTHORIZED in both schemes, the mirror's keys and flags, tending: claim/drive/register and their limits); nwc-test.js (monthly refusal naming the period, get_budget, a counter from last month reads as nothing, the revoked connection answered UNAUTHORIZED, no 13194, revokedAt in the snapshot, forgotten after 31 days, the earlier date wins); nwc-settings-ui-test.js (the form's period choice, the card's wording, Revoke dates it); ark-renewal-sync, sync-blob, sync-outbox and spending-restore tests pass.

BTCPay's NWC connector requires get_info, make_invoice, lookup_invoice
and list_transactions; we never offered lookup_invoice, so it refused the
connection string.
- ArkManager.lnLookup answers lookup_invoice from wallet state (by hash or
bolt11, either direction; pending/settled/expired/failed, preimage once
claimed). A retry's several actions on one hash defer to the furthest.
- The open app pushes a pending receive along before answering, so a
merchant polling sees it settle.
- The service worker now answers make_invoice and lookup_invoice too, and
claims a paid invoice's HTLCs during the lookup: a BTCPay sale settles
with the wallet closed. Its list_transactions reports receives as well.
- get_info and the 13194 info event list the new method.

The wallet used to add two to four seconds of its own around a Lightning
send: a random pause plus a relay look-back before paying, and a
two-second poll for the result after. The notifier's claim now decides
who pays in one round trip, with the relay look-back kept only for
replays and for when the notifier gives no verdict; a phone answering
from behind another app waits a second so a desktop tab wins the claim
instead of paying at a throttled crawl. After the send, one held
CheckLightningPayment call brings the preimage the moment CLN has it —
for wallet-connect pays, the background worker, and the app's own Send.

Every awake device of a wallet hears a wallet-connect pay request within
the same second, and the per-tab lock only reaches one browser profile:
two profiles on one laptop each locked an HTLC for the same 21-sat zap.
The push notifier now hands each pay request to the first device that
claims it; a device that loses the claim stands down silently, and a
device that cannot reach the notifier answers as before so nobody goes
quiet over a hiccup. The worker path claims the same way.

Every open tab of the same wallet sees every wallet-connect request. Two
hidden tabs on one laptop both tried to pay the same zap: the ASP refused
the second with "payment already in progress", and that error reached
Amethyst half a second before the first tab's preimage. A Web Lock per
request now lets one tab (or the worker) answer while the rest stay
quiet, and a device that does meet "already in progress" waits for the
sibling payment's outcome — relaying its preimage only if the payer never
speaks — instead of shouting a failure over sats that went through. The
losing side also stops writing a failed row into history for it.

Loose leader election for pay_invoice across a user's open tabs: before
handling, defer a beat and stay silent if any reply for the request
already exists on the relays; and before sending an ERROR reply,
re-check — a device that lost the race (mid-init, stale state) was
replying 'superseded' after another device's success, and clients
trusted the later error, marking paid zaps as failed.

onRequest handled every request against the connection object captured
at listen() time, so each spend was recorded against a stale snapshot —
spentToday restarted from the old value on every payment and the daily
budget never actually bound. The connection is now re-resolved from
stored state per request, which also stops serving a connection revoked
on another device mid-session. recordSpend now publishes the sync
snapshot so the spend (and the payment's movement + vtxo change) reaches
the user's other devices. Test: two payments must accumulate to 52.

A connection made on the phone existed only there, so only that device could
answer it — and if that device was asleep, a client just spun. Connections now
ride the encrypted device-sync snapshot, so whichever device is awake can
serve them. The snapshot is nip44-encrypted to a key derived from the seed,
the same channel that already carries ark vtxo bytes and gift secrets.
The merge is a union by id with two rules that matter:
- REVOCATION WINS, so a stale snapshot can never resurrect a revoked
connection
- the higher same-day spend wins, so a stale device cannot hand a connection
back its daily budget
Creating or revoking a connection publishes the snapshot immediately rather
than waiting for the next state change.

The connection URI advertised up to four relays (sync relays + profile
relays) while the subscription only ever listened on the sync relay, so a
client could publish its request somewhere hal wasn't and spin forever
waiting for a reply. Amethyst did exactly that.
NWC now has its own relay list used for all three things that must agree:
the URI, the subscription, and the replies. It no longer depends on device
sync being enabled, which would otherwise have made the whole wallet service
a silent no-op.
Also republish the kind 13194 capability event on every start — a client that
can't find it just spins, and a single publish at creation time is easy for a
relay to miss.
The relay transport is now injectable so the protocol can be exercised
without a live relay (tools/nwc-test.js).

Other apps can connect over nostr and pay from this wallet without touching
its keys, within a per-payment and daily budget the user sets, revocable at
any time. hal holds no native Lightning balance, so every operation runs over
Ark: pay_invoice takes the swap bridge when configured and falls back to the
ASP's lightning-send, make_invoice mints on the ASP. NWC availability
therefore tracks Ark availability.
- kinds 13194/23194/23195, nip44_v2 and nip04, replying in whichever scheme
the request used; every request gets a reply so clients never hang
- each connection gets its own service keypair, so revoking one can't affect
the others and none is tied to the user's nostr identity
- budgets are checked BEFORE spending, not reconciled after
- requests are ignored unless signed by that connection's client key, and
replayed/stale events (>120s) can't re-trigger a payment
- Settings card to create, show (URI + QR) and revoke connections, and it
says plainly that this only works while a tab is open
tools/nwc-test.js drives it as a real client: both encryption schemes, budget
refusal with a genuine over-limit invoice, unsupported-method errors, and a
request from an unauthorized key being ignored.
