The global Settings tab no longer shows the recovery phrase / public key — those
live only on each wallet's settings page now (the watch-only 'load seed' upgrade
stays in the global tab since it targets the active wallet). On the per-wallet
page, recovery phrase moves to the top and auto-logout to the bottom. Removes the
now-dead pubkeyCard/autoLockCard. Lowercases 'THIS' in the auto-logout copy.

The accounts list now shows a settings cog (instead of a rename pencil) that
opens a per-wallet settings page: edit name, set auto-logout (moved here from the
global settings tab), reveal the recovery phrase, and show the public key (zpub)
— all read from the account itself, so it works for any wallet, not just the
active one. Room for more per-wallet settings later.

The network card is now just the network picker. Each network's endpoints
(Electrum server + block explorer) live solely in the Data source card, whose
options change per network and are stored per network (so switching networks
remembers each one's choice). Removes the duplicate regtest Esplora/WS fields.
Adds mutinynet (signet — testnet address format, explorer at mutinynet.com).
Per-network defaults: mainnet → coinos Electrum, testnet/mutinynet → explorer,
regtest → local Fulcrum. Fixes tx-explorer links to use each network's web base
(no double /testnet).

The data-source picker is now just Electrum vs Block explorer; coinos is the
first/default entry in the Electrum server list (our own Fulcrum), with public
servers as failover. Drops the standalone 'coinos' mode and the retired watcher
shim. Old 'coinos' selections migrate to electrum.

Flip COINOS_ELECTRUM on: the default 'coinos' mode is now a full Electrum backend
served same-origin at wss://halwallet.app/electrum (nginx -> Fulcrum on cs, synced
+ using bitcoind hashblock ZMQ), with the public Electrum servers as automatic
failover. Replaces the explorer-REST-data + coinos-watcher-push setup — one
connection to our own node now serves both data and instant notifications.
Verified the endpoint end-to-end through Cloudflare (server.version + get_balance).

_rpcId could go non-numeric, so ++ produced NaN and requests serialized with
"id":null. _handleRpc matches responses with `msg.id != null`, so every
data-call response was dropped → the call timed out → _reconcileHeld skipped
the address → confirmations never reflected (until an unrelated full refresh).
Coerce to a number on every send. Verified via CDP: a mined deposit now flips
pending→confirmed in ~1s instead of stalling.

Regtest now talks to a local Fulcrum over its native Electrum WebSocket for
both chain data and realtime push, instead of esplora REST + a separate watcher.
This matches prod (Fulcrum) and gives ~2-3x lower latency than the previous
electrs polling. getBackend()/electrumCandidates() route regtest to the
Electrum backend at the configured Fulcrum WS (default ws://localhost:50003);
the wallet's realtime path is ungated for regtest. ElectrumApi already covers
every call (utxos, history, fees, broadcast), incl. the swap feature.

On regtest there's no realtime push (coinos watcher is mainnet-only), so the UI
only updated on the 5–10s poll — a funded tx took a while to appear and a
just-mined block stayed "pending" until the next reconcile. electrs speaks the
Electrum protocol the watcher already understands, but only over TCP; route it
through a small WS<->TCP bridge (see coinos-server/electrum-ws) so the wallet
subscribes scripthashes and reconciles instantly on each notification. Data
still comes from esplora; this only adds the push channel. Configurable in
Settings (default ws://localhost:50003); falls back to polling if unreachable.

New `regtest` network (bech32 `bcrt`, testnet version bytes) selectable in
Settings, pointed at a configurable local Esplora (default http://localhost:3000).
Adds getNetwork/setNetwork + getRegtestEsplora persistence, a regtest branch in
resolveHosts, mainnet-only gating for the realtime watcher + Electrum backend,
and a Network selector card. Account loading reads the active network.

The light frontier poll walks past already-used addresses, and _reconcileHeld
refreshed held-coin balances but not the history tx summaries — so a
pending->confirmed transition only showed via the realtime WebSocket push.
Backends without that push (custom electrs/esplora, regtest) left the History
row stuck on "pending" even after the tx confirmed. Re-fetch and update tx
summaries for changed held addresses during reconcile.

The Electrum data path fired every request at once, so a scan burst dozens of
calls at a rate-limited public server, which then dropped some (the timeouts).
Add a concurrency cap (4 in flight; Electrum pipelines, so it stays fast) with
excess queued — mirrors the Esplora scheduler's intent. Verified a full scan via
the public jochen server completes in ~4.5s with peak concurrency 4, no timeouts.
The throttle queue is drained on disconnect/stop alongside in-flight calls.

Two Electrum-backend issues:
1. Stale balance after a send made on another device: _reconcileHeld set each
address's balance from get_balance/address-stats, where a confirmed coin being
spent by an unconfirmed tx STILL counts as confirmed (with a compensating
negative unconfirmed). So a device that didn't make the send kept showing the
spent coin's value. Now the entry balance is derived from the actual unspent
set (listunspent, which excludes spent coins) — verified a spent coin clears.
2. Per-address rescan failing with 'electrum timeout: blockchain.scripthash.
get_balance': public Electrum servers can drop a response or the socket can
flap mid-call. _rpcCall now retries a couple of times on a fresh id (12s each)
before giving up.

On the Electrum backend the post-send rescan is many round-trips, so the balance
lagged a few seconds. Now a successful broadcast immediately applies the tx
locally (applySentTx): drop the spent coins, credit change as pending, add a
pending history row, recompute the balance, and emit — so the UI reflects the
send instantly. The realtime watcher / backstop poll reconciles and fills in the
confirmation once the explorer has indexed it (no immediate rescan, so a
not-yet-indexed tx can't briefly revert the optimistic state). Verified the
balance/utxo/history math.

The Esplora broadcast cleared its abort timer right after fetch() resolved, so
the subsequent res.text() body read had no timeout — a stalled response body
hung the whole broadcast (and the send spinner) indefinitely, with the tx never
reaching the network. Keep the abort timer active through the body read, and add
a hard 30s outer timeout in the send handler so a wedged broadcast always surfaces
as 'timed out — try again' instead of spinning forever. (The silent-payment tx
itself is valid — verified structure + BIP143 signature over the real outputs.)

broadcast() set the success result but kept ui.busy=true and didn't render until
after awaiting wallet.scan(), so the 'Sign & broadcast' button spun for the whole
post-send rescan (slow under rate-limiting / on the Electrum backend) — looking
stuck even though the tx had already broadcast. Now it shows the success screen
the instant the broadcast resolves and refreshes balances in the background.

- goHome: when a wallet is open, the logo goes to its Receive page (its tabs)
instead of the create/import screen — so it's always a way back to your wallet.
Only with no wallet open does it show create/import.
- Paste buttons: a clipboard 'Paste' icon on the send address field and the
import (seed/key/xpub) and 'load seed to spend' fields, filling them from the
clipboard. Hidden where the Clipboard read API isn't available.

A vault exists → Accounts screen shows Change password: enter the current
password, then a new one (with confirm; leave blank to remove it). It decrypts
the actual vault and re-encrypts it with the new password, so wallets not loaded
in the current session are never dropped. Keeps the in-memory password in sync
when the vault is already unlocked. Verified the re-encrypt round-trip
(old rejected, new works, blank works).

The logout timer is now an account setting (stored per account in the session and
the durable directory), not a global one, and it removes only that wallet from
the device — its session entry, directory entry, cached state (xpub + seed keys),
and its vault entry — leaving other wallets untouched.
- wipeAccount(id) surgically removes one wallet; the active one falls back to the
next account (or the unlock screen).
- Background-away timestamp drives per-account evaluation on resume/boot; an armed
timer fires for the soonest-due wallet so a blurred-but-visible window still
signs out on time. Overdue saved wallets are removed from the vault when it's
unlocked (the only point we can re-encrypt it).
- New cacheKeyFor() export lets app code target one wallet's cache keys exactly
(verified against the wallet's seed/xpub/watch keys).

With a logout timer set, signing out now removes everything from the device
including the password-protected vault — nothing survives, so the recovery
phrase is required to return. Updated the setting copy to say so.

A vault saved with no password auto-unlocks on open, which would undo the
sign-out. When a logout timer fires (or a boot is overdue), remove it too —
only a password-protected vault survives.

Auto log-out: a Settings option (Never default, 1m/5m/1h/1d) that, after the app
has been backgrounded/unfocused that long, signs out completely — clears the
session, the watch-only directory, and cached balance/history from the device
(only password-saved vault wallets remain). The countdown only runs while the
app is hidden/unfocused, never while it's open and focused; a background
timestamp covers throttled/discarded-tab cases on resume/boot.
Optional vault passwords: drop the 8-character minimum and allow a blank
password. A blank-password vault auto-unlocks on open with no prompt (Save to
device with no password = just persist). Verified blank round-trip + wrong-
password rejection.

Closing the browser without 'Save to device' used to wipe the wallet entirely.
Now every wallet's account xpub is mirrored to a durable localStorage directory
(never the seed), so it survives a session wipe as a watch-only entry — you keep
seeing balance and history, and re-enter the seed to spend again.
- Durable account directory: saveDirectory() mirrors {id,label,xpub} for every
account; restore falls back to it as watch-only when there's no session/vault.
- Instant view: a full wallet also caches under its xpub key, so the downgraded
watch-only shows balance/history immediately (no rescan). Verified round-trip.
- Re-enter seed to spend: the Send tab (now shown for watch-only) and Settings
prompt for the recovery phrase / xprv; it must derive to this wallet's xpub
(verified via accountXpubFor — wrong seed/passphrase rejected), with an option
to Save to device at the same time. Upgrade is in place (id/label/cache kept).
- Vault merge now dedupes by xpub so saved + non-saved wallets coexist without
duplicates.
Privacy note: the xpub now persists by default (someone with device access can
see balance/history without the seed); 'Remove' clears it.

Failover (live now): the Electrum backend now tries an ordered list of servers,
advancing to the next when one fails to connect or dies within ~5s. Named public
presets fall over to the other public servers; a custom your-node URL does NOT
fall over (won't silently leak your addresses to a server you didn't pick).
Verified: dead primary → auto-advances to a working server.
Cutover switch (dormant): COINOS_ELECTRUM (false) flips 'coinos' mode from
explorer-REST + watcher push to a full Electrum backend pointed at
wss://coinos.io/electrum, with the public servers as failover, and disables the
watcher for coinos mode. Flip it true once Fulcrum serves data behind that
endpoint — no new logic needed at cutover. Flag off = current behavior exactly
(default coinos → esplora + watcher), so this ships safely while Fulcrum syncs.

Replace the Esplora|Electrum backend toggle plus the separate 'Instant
notifications' on/off with one 'Data source' selector:
• coinos (instant) — default; explorer data + coinos push
• Block explorer — REST + polling, nothing sent to coinos (the opt-out)
• Electrum server — one WS server for data + push (your node / public)
Picking a non-coinos source IS the privacy opt-out, so the standalone toggle is
gone. A single 'mode' setting drives getBackend()/getRealtimeEnabled(), so the
wallet/wsUrl logic is unchanged; existing per-feature settings migrate in
(realtime=off → explorer, backend=electrum → electrum). coinos⇄explorer just
flips the watcher (no rescan); to/from electrum rebuilds the backend.
Sets up cleanly for a future coinos Fulcrum: 'coinos' mode upgrades from
REST+watcher to a full Electrum backend transparently.

Settings → Data source now offers 'Electrum' alongside the Esplora REST explorer.
One Electrum WebSocket serves BOTH the wallet's data queries and scripthash push
notifications, so pointing Hal at your own Fulcrum/electrs gives a fully
self-hosted setup — no coinos, no public REST, nothing shared off your node.
- src/electrum.js: ElectrumApi maps the Esplora shapes the wallet consumes onto
Electrum methods (scripthash get_balance/listunspent/get_history, estimatefee,
transaction.broadcast). electrs has no verbose tx lookup, so it parses raw txs
and resolves input values from parent txs to compute fees (cached, in-flight
deduped, bounded-parallel). Validated field-for-field against mempool.space:
addressTxs (fee/vin/vout/status), getTx, outspend, balance, utxos.
- wallet.js: the realtime socket already spoke Electrum's notify protocol; added
request/response (_rpcCall) so the same connection answers data calls. Real
Electrum notifications carry no tx data, so they reconcile via the backend.
Replaced the fragile newline parser with a string-aware brace-depth scanner
that handles every framing (newline, one-per-frame, concatenated, split) —
fixes a buffer-poisoning hang under concurrent calls; also hardens the coinos
watcher path. Esplora stays the default; nothing changes for existing users.
Verified end-to-end against blockstream's electrs: concurrent transport, a full
fresh-wallet scan (~2s), and the parser unit-tested on all framings.

Pay sp1… addresses: the wallet derives the one-time taproot output from the
recipient's address + the transaction's own input keys (ECDH), so payments are
unlinkable on-chain with no interaction. New src/silentpay.js implements the
sender derivation + bech32m address decode, validated against the official
BIP-352 test vectors (all P2WPKH-input / single-recipient cases pass; the rest
exercise input types Hal never spends).
buildTx detects sp1… recipients, selects coins against a same-size placeholder
taproot output, then swaps in the script derived from the final input set
(updateOutput). Works for normal sends, multi-recipient, and send-max. The
review screen shows the sp1… address with a 'Silent payment' label (the on-chain
output is a derived one-time taproot address). End-to-end signing verified.

The WS watcher is the one place the app shares addresses off-device (it
subscribes your scripthashes to coinos to push instant payment updates). Add an
'Instant notifications' toggle in the explorer settings: off means the app never
connects to coinos and polls your chosen explorer instead — a bit slower, more
requests, but nothing is told to coinos. wsUrl returns null when disabled, so
startRealtime cleanly skips the socket and relies on the polling fallback.

Opening a gift link generates a wallet only to claim into. Mark it provisional
so bailing from an already-claimed gift (Go to home / logo) discards it instead
of leaving an empty account in the session list. It's committed — kept for good —
the moment the user claims, chooses 'Create a wallet anyway', or otherwise enters
the wallet (incl. a refresh). Critically, commit on claim *success* so the backup
step can't discard a wallet that just received funds.

Save the wallet-screen nav (tab and open tx detail) to sessionStorage on each

Gift links now carry a compact binary encoding of just the claim-essential data
(presigned inputs + the committed change output) instead of a full PSBT (~25%
fewer bytes), base32-encoded and served at an uppercase /g/<code> path. The QR
renders the uppercase URL in the QR alphanumeric mode (5.5 bits/char vs byte
mode's 8), so the grid drops from ~73 to ~53 modules — much easier to scan.
- wallet: _encodeCompactGift/_decodeCompactGift + _giftTx dispatcher; legacy
base64url-PSBT links still claim (auto-detected by a magic byte). Verified
round-trip + claim-byte-identical across 1/2/3-input and whole-balance gifts,
against the real exported preview/claim/outpoint functions.
- app: giftUrl uses /g/<code>; opener parses /g/ (and legacy #gift=); QR uses
uppercase + Alphanumeric mode (qrSvg gains a mode option w/ byte fallback).
- nginx already SPA-routes /g/*; the SW serves the shell for the new path.

Opening a gift link now checks whether its funding coin is already spent — via
the Esplora outspend endpoint, which reports a spend even by an unconfirmed
claim. The Claim button is gated until that check passes; if the coin is spent,
show an 'Already claimed' screen with a link to the claim tx instead of a
claimable amount. doClaim also re-checks on broadcast failure (the race window),
and refuses to run while unchecked/taken — so a second opener can't attempt a
doomed double-spend.

The watcher's block (rawblock) push now carries confirmed=true + the block time,
and _applyTxNotification flips the matching history row and coins from pending to
confirmed directly — for incoming and outgoing txs (flag-only, so no overcount).
Confirmations no longer wait on a mempool.space reconcile; the 30s backstop poll
just fills in block height / fee afterward.
