Every frame the History tab:
- hashed the txid, amount, confirmations, time, type and address of
all N transactions (about 0.6-5 ms at 5k-20k) to decide whether its
totals and its merged, sorted row list were stale;
- copied every chat txid into a fresh set;
- ran the type and search filter over all N rows, with up to three
case-insensitive substring searches each.
The totals and the row list now key on tx_revision (the row list also
on the sort mode), the Message badge and the Chat filter use the chat
store's txid index, and the filtered rows are rebuilt only when the row
list, the type filter, the search text or, under the Chat filter, the
chat store changes. A frame is now a few compares plus one txid lookup
per row of the current page. An unchanged full-node refresh no longer
rebuilds the totals and the row list either: the old fingerprint folded
in the refresh time.
On lite, a change to only a memo or a sender address now shows at once.
The old fingerprint left those fields out and relied on a refresh time
that lite never sets, so such a row stayed stale until something else
in the list changed, such as the next block.

The History tab copies every chat txid into a fresh set each frame to
badge and filter chat transactions: M string allocations for M chat
messages. ChatStore gains hasChatTxid(), an O(1) lookup in a txid index
that is rebuilt only after the store changed (append, delivery update,
erase, clear) and never built for an empty store. clear() also drops
the index, so no chat txids linger after a lock. The History tab moves
to it in the next commit.
The chat note-buffer pump, which runs every frame while chat is idle,
built the whole conversation-id list just to see whether the store was
empty; it now asks store().empty(), O(1) instead of O(M).

WalletState had no change signal for its transaction list, so a UI
cache had to fingerprint all N transactions every frame to notice an
update. It now carries tx_revision, a counter that only increases;
clear() on disconnect bumps it instead of resetting it, so a cache
built before a reconnect or wallet switch can never match again.
- Every writer of the list bumps it: the full-node refresh, loading the
cached history, adding, completing and removing a pending send, a
mining-address relabel, the lite refresh and the screenshot demo
rows.
- The full-node refresh and the lite refresh (every ~2 s) swap in the
new list only when it differs field by field, the amount compared
bit-exactly because -0.0 and +0.0 print differently. An unchanged
refresh keeps the list and the revision; the compare costs O(N) per
refresh, not per frame.
Nothing reads the counter yet.

The image picker decoded up to 6 full-size images per frame on the UI
thread to make its thumbnails (1.5-2.7 s per frame with 12 MP photos,
until the visible grid filled) and read every .gif/.webp a second time
just to see whether it animates. Thumbnails were freed only on navigate
or close, so a large folder and every hovered animation (up to ~20 MB
each) stayed resident.
Thumbnails now decode on util::StartImageDecode workers (at most 2 at
once, so the top of the visible grid fills first) and the UI thread
uploads up to 8 small textures per frame. The animation badge comes from
the same decode, with no second read. Hover previews get their own
2-slot lane, and the picker asks for a frame every 100 ms while anything
is pending; under idle pacing a deferred thumbnail used to wait for input
or the 2 s tick.
Behaviour changes:
- thumbnails and hover frames are LRU-capped at 64 MiB per folder;
evicted ones re-decode when they are needed again;
- leaving an animated thumbnail before its preview finishes decoding
cancels it (re-hover restarts it); a finished preview is kept;
- animated WebP files get a real thumbnail instead of the placeholder;
- images above the decoder's limits show the placeholder.

The Contacts tab read, decoded and downscaled custom avatars inside the
draw call, two per frame, rows scrolled out of view included: a 12 MP
photo froze the window for 0.25-0.45 s, a long GIF for up to 1.5 s, and
the avatar cache was never evicted. "Add image" decoded the picked file
and copied it inside the picker's confirm callback, freezing it again.
Avatars now decode on util::StartImageDecode workers (at most 2 at once).
The UI thread only uploads finished frames, at most about 4 MB per UI
frame, and asks for a frame every 100 ms while anything is pending;
under idle pacing a deferred avatar used to wait for input or the 2 s
tick.
Behaviour changes:
- an avatar scrolled out of view is not decoded until it scrolls in
(the badge shows for 0.1-0.3 s the first time);
- avatar textures are LRU-capped at 128 MiB; the least recently drawn
go first, never one drawn on-screen in the previous Contacts frame,
and they re-decode on scroll-back;
- an animated avatar starts playing once all its frames are uploaded;
- an import is validated and copied on a worker: the avatar appears
0.1-0.5 s after confirming and Save/Add stays disabled until it does;
a result only lands in the dialog session that started it;
- the copy goes to a temporary file renamed over the target (retried
briefly), so a crash or a failed copy never leaves a truncated avatar
or removes the existing library image;
- imports get the decoder's limits, and an animated WebP can now be
imported (it always failed with "couldn't be loaded").
Applying an import also no longer destroys an avatar texture the same
frame has already drawn (a use-after-free on DX11).

Image decoding lived in the GL texture file and had no limits: a file of
any size was read whole, stb and libwebp allocated whatever the header
claimed (a WebP alone up to 1 GB), and a GIF was decoded at full size,
every frame, before the 300-frame cap. A 720p 150-frame GIF avatar cost
0.2-1.5 s and 140-370 MB on the UI thread. stb's GIF loader also read
before the start of its buffer on disposal-3 frames, and when a long GIF
ran out of memory it freed the frame delays that the caller then freed
again (an abort).
Decoding, and the stb implementation, now live in the GL-free
util/image_decode_core, safe on any thread:
- the header is probed first; stills above 256 MP, any GIF or animated
WebP canvas above 32 Mi px, and files above 256 MiB are rejected
before anything is allocated (real photos, 200 MP phone shots and
wide panoramas still load);
- a GIF decodes one composited frame at a time, downscaled as it goes,
and stops at the frame cap: peak memory is stb's working buffers, two
canvases and the small frames; a truncated GIF keeps the frames
decoded so far;
- a header stb cannot read means "unsupported", never a blind decode;
- decodes above 16 MP run one at a time; a decode can be cancelled
between frames.
util::StartImageDecode runs one decode on a detached worker that owns its
job and its lane's in-flight counter, so nothing waits at exit; the next
commits move avatars and the image picker onto it. The limits apply now
to avatars and the picker's hover previews; thumbnails and avatar imports
get them when they move to workers.

On a first run or after an upgrade, Windows release builds wrote the
bundled Sapling params, asmap, node and miner (about 88 MB) in
App::init, before the first frame: 0.5-3 s of frozen blank window, 5-30 s
on a slow disk or under antivirus. Zip, AppImage and .app builds copied
the bundled files into the daemon dir and hashed the 51.5 MB of params on
the UI thread at the first node start, a 0.3-1.5 s freeze in the wizard
or the connect loop.
A stat-only check at startup decides whether anything is missing, stale
or unverified; a normal launch starts no thread and shows nothing.
Otherwise one background job extracts (Windows) or copies (Linux, macOS)
the files, then verifies the params once:
- The first frame paints at once. If the job takes longer than 0.4 s, a
chip at the bottom shows "Preparing wallet files... N%", then
"Verifying wallet files...".
- A node start on the UI thread while the job runs is deferred and
replayed when it ends (never into a bootstrap download, a restart or a
live connection); worker threads wait, and give up on quit. After an
upgrade that ships a new miner, the node starts after the miner is
written instead of before. Pool-miner starts and the miner version
check wait too, so the old miner is never run or reported while it is
being replaced.
- Each file goes to "<name>.partial", is flushed and renamed into place
under one lock shared with the daemon start, the bundled-node
reinstall and the miner extraction, and the job stops between 4 MB
chunks at shutdown. An interrupted write used to leave a truncated
binary that was trusted forever; a leftover .partial is now removed.
Other behaviour changes:
- Linux and macOS full-node builds copy the bundled node files (about
77 MB) into the daemon dir at first launch, even if the wallet ends up
on an external node; before, this happened at the first embedded start.
- Lite no longer writes the 53 MB of params and asmap it never reads.
- A disk-full or permission failure that leaves the node files unusable
shows a warning; a miner blocked by antivirus alone does not.
- A corrupt or truncated param in a zip, AppImage or .app install is
replaced from the bundle and verified again instead of trusted forever.
- Reinstalling the bundled node holds off the connect loop and a deferred
start for its whole run (either could launch the old binary while the
new one was written), and is refused while another restart is running.

On Windows every full-node launch read the whole installed dragonxd.exe
(about 16.7 MB) on the UI thread and byte-scanned it for a version
string, to decide whether to offer the bundled node, which only needs
whether the file exists and its size. getInstalledDaemonInfo() takes a
scanVersion flag, and the update offer now only stats the file.

Every open of the Wallets dialog, Refresh, folder add or remove, and Open
on a stale row walked each user-added folder recursively on the UI thread
before the dialog drew: up to 40,000 entries per folder, roughly
50-150 ms warm on Linux and seconds on a cold disk, a network share or
Windows.
The datadir listing (a few top-level files) stays synchronous, so a
wallet just created shows at once. The recursive walk runs on a detached
worker with the same depth, hit and entry limits; its rows are merged at
the start of a later frame and only the new rows are probed.
- The dialog opens at once with the datadir rows. The external rows
arrive when the walk ends, with "Scanning folders..." beside the
scanned-folders caption, and the card grows once.
- Reopening within 60 s with the same folders reuses the last walk
without touching the disk, so its rows and sizes can be up to a minute
stale: a wallet copied into a folder in that minute needs Refresh.
Refresh and Open on a stale row always walk again.
- While a walk or a wallet probe runs (up to 30 s) the dialog keeps
frames coming, so rows and badges appear without moving the mouse.
- The 200-row cap now holds across all folders; each extra folder could
add one row past it.

Open on a wallet row whose file was moved or deleted after the list was
built rebuilt the list from inside the dialog's row loop. The loop still
held a reference to that row and walked a sort order sized for the old
list, so the click read freed memory and could index past the end. Open
now flags a rescan for the next frame; the vanished row drops out one
frame later, with no crash.

The backend's error for a key it doesn't recognize repeats the key
("'<key>' was not recognized as either a spending key or a viewing
key"). Import passed that text on as its error, so a mistyped private
key was written to the lite log (shown in the Console tab) and to the
Settings status line. A failed import now carries a fixed reason
(unrecognized format, wallet locked, key already exists, could not be
decoded, or rejected), which is all the log records. Settings shows
"Couldn't import the key — check it, unlock the wallet (if encrypted)
and try again." instead, translated in all eight languages.

Clicking the Network-tab card of the server the wallet was already
pinned to and connected to tore the controller down and reopened the
wallet against the same server. That click is now a no-op. A wallet that
failed over to another server still reconnects, which retries the pinned
one.

New address, Import key, Encrypt and Remove encryption called the
backend on the UI thread. Each ends in the backend's save, which waits on
the lock a scan holds for its whole duration and every refresh read holds
briefly, so during a scan the window froze until the scan ended. A create
or restore with a passphrase encrypted and saved just after its first
scan had started: for a restore, a freeze for the whole initial scan. A
server switch destroyed the old controller on the UI thread and joined
its refresh worker, which can sit for minutes in a read against a dead
server (each balance, notes or list read retries for ~62 s).
- The four ops run one at a time on a background lane and their results
are applied on the main thread; Settings shows "Working…" meanwhile.
Key and passphrase copies are wiped after the call, or when a queued
op is dropped.
- A create or restore encrypts and saves (an open unlocks) before the
first scan starts, so the save takes milliseconds and the scan runs on
the encrypted file.
- Import, Encrypt, Remove encryption and Receive's New address are
disabled while a scan runs ("Wait for blockchain to sync"); Redownload
blocks is disabled while an op is queued.
- A switch retires the old controller without blocking (queued ops
dropped, pending ones reported failed, its client shut down) and
destroys it on a background thread. It no longer saves on the way out:
the new client re-scans the blocks since the last save, as after a
restart.
- A switch waits for an op in flight, at most 15 s, so the op can't
finish and save on the old client while the new one owns the wallet
file. The Network tab already shows the new selection meanwhile.
- The refresh worker stops between backend commands, skips the remaining
server reads once one fails, and then retries after 4, 8, then 15 s
instead of every 2 s.
- Quit waits up to 2.5 s for an op in flight, e.g. Encrypt's save.
Encrypt and Remove encryption now report a failed save: the backend
returns it as a JSON error that the old check never saw, so the failure
was reported as success. The trimmed copy of a key typed into Import is
now wiped too, and stopping the refresh worker can no longer miss its
wakeup.

A FIFO of blocking jobs, run one at a time on a background thread that a
post starts when none is running and that exits once the queue is empty.
Each job returns a completion, and completions run only in pump(), on
the owner's thread. Unlike RPCWorker and AsyncTaskManager nothing ever
joins: abandon() (also run by the destructor) drops queued jobs and
undelivered completions and refuses later posts, and a job stuck in a
blocking call finishes on its own thread. It is meant for backend calls
that can wait out a long scan and may have to be given up. post()
reports a dropped job (abandoned lane, or no thread could be started),
and waitIdle() is bounded.

The daemon's RSS was read on the UI thread: a scan of every /proc entry
on Linux (1-7 ms), a forked ps on macOS (up to ~30 ms). The mining poll
probed every 1-5 s on every tab, and the Mining tab's memory bar probed
again every 1.5 s.
util::BackgroundSampler now runs the probe on one lazily started thread
and caches the result. getDaemonMemoryUsageMB() returns the last sample
and asks for a new one at most every 3 s, and only while the Mining tab
memory bar or the Peers tab Memory cell is drawn: nothing on other tabs
or while minimized. EmbeddedDaemon::memoryProbe() hands the sampler a
pid snapshot (on Windows the value read from the owned process handle),
so nothing off-thread touches daemon state. The mining poll does no I/O
any more; it carries the last sample. Both shutdown paths stop the
sampler.
Fixed along the way: an unreadable /proc made the directory iterator
throw on the UI thread; the scan now just stops.
User-visible:
- the Peers tab Memory cell keeps updating during sync and shows an
external daemon's memory (it showed the mining poll's value, which
pauses during sync and covers only the embedded daemon);
- the Mining tab memory bar refreshes every ~3 s (was 1.5 s).

Finding the lowest block a node still has (Settings > Rescan, and the
automatic reconcile after a bootstrap) ran a binary search of about 42
synchronous getblockhash/getblock calls on the UI thread, each waiting
for the RPC connection behind any wallet scan (10-20 s on a big wallet)
and each with a 30 s timeout. The window froze for that long.
It now runs as one task on the wallet RPC worker, bounded to 90 s, and
the answer comes back on the UI thread; meanwhile the dialog shows
"Checking which blocks..." with Rescan disabled. An answer from an
earlier connection counts as "could not tell", and one for an earlier
opening of the dialog is dropped. The search probes block 1 first, so a
full-history node answers in one probe, and it answers "could not tell"
at once while a runtime rescan holds the lane.
Fixed along the way: any probe error (timeout, busy node) read as "block
missing", so a busy node could get a bogus "bootstrapped, rescan from
the tip"; and a non-string getblockhash reply never called back, leaving
the dialog on "Checking..." for good. Only the daemon's "can't read
block" error now counts as missing; anything else means "could not
tell".
User-visible:
- after a bootstrap, a probe that cannot tell is tried up to 6 times,
30 s apart and only while the node is not busy, then a toast points
to Settings > Rescan, instead of falling back to the -rescan
restart, which fails on a bootstrapped node;
- the Settings Rescan dialog warns when the probe could not tell.
Two new strings, translated into all eight languages.

The CoinGecko price, tickers and market chart and the exchange candle
GETs ran on the wallet's RPC worker, the same FIFO lane as balance,
history and sends. A slow or blocked endpoint held that lane for up to
10-12 s per price or ticker fetch and 2 x 30 s per chart or candle job,
and a wallet scan in turn delayed the price. At quit a hung GET held
shutdown until the 15 s watchdog cut teardown short.
They now run on their own RPCWorker thread; results are applied on the
main thread and wake the idle loop. A new util::httpGet takes a cancel
flag (checked by libcurl's progress callback), sets CURLOPT_NOSIGNAL and
returns the HTTP status and error; httpGetString wraps it. Shutdown sets
the flag, so queued GETs return at once and one in flight aborts within
about a second. The price uses a plain in-flight flag instead of the
connection-scoped refresh job, so a disconnect no longer throws away a
good in-flight price and leaves it loading until the next tick.
User-visible:
- chart and candle GETs use a 5 s connect / 20 s total timeout (were
15 s / 30 s);
- the price request goes through the shared GET: User-Agent
ObsidianDragon/1.0 (was DragonX-Wallet/1.0) and a 16 MiB reply cap;
- market fetches on connect start alongside the wallet refresh instead
of queuing behind it.

Every history refresh, address refresh, connect and lock-state check
rewrote the encrypted tx-history snapshot on the UI thread: a JSON
document of every row, its encryption, then INSERT OR REPLACE and a
prune, an estimated 40-120 ms on a 5k-transaction wallet, even when
nothing had changed.
Now a signature of what would be stored (about 1 ms on 5k rows)
decides whether to write. Confirmations count only by the thresholds
the UI reads (conflicted, pending, 1-9, 10-99, 100+); per-address scan
heights, exact confirmations and the tip drift every block and form a
separate part.
- Routine refreshes write a content change at most every 20 s (a
deferred one is released from the update loop) and the per-block
drift at most every 10 min. Nothing changed means no write.
- A mining-address relabel, a passphrase change, a rescan, a
disconnect, a wallet lock and exit write whatever is not on disk yet,
at once.
- The UI thread only copies the rows and the key into a job; a single
background writer (newest job wins) builds, encrypts and stores it. A
failed write is retried.
- Exit queues the final write so it overlaps the daemon stop, then
waits up to 3 s for the writer; a disk that hangs past that keeps the
previous snapshot.
- A loaded snapshot counts as stored, so the first identical refresh
doesn't rewrite it. An address refresh re-keys the snapshot only when
the address set changed.
After a hard kill the snapshot can now be up to ~20 s behind for rows
and 10 min for scan heights, exact confirmations and the tip (it was
one refresh); the first refresh replaces it either way. Lite builds,
which never read this cache, no longer write it on Refresh or a mining
relabel, and the screenshot capture mode's demo rows never reach it.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The tx-history cache was only ever used from the UI thread and had no
locking. To let snapshots be written from a background thread:
- every SQL statement runs under one database mutex and the key fields
under a second one, taken after it and never held across I/O or the
key derivation;
- a write is a self-contained, move-only SnapshotJob holding the rows
and a private copy of the key, which is wiped after the write or when
a job never runs; the JSON build and encryption hold no lock;
- a job with an all-zero key is refused instead of overwriting a good
snapshot with one nobody can read;
- the prune after a write also keeps the wallet unlocked now, so a late
job for the previous wallet can't delete the salt of the one just
switched to;
- keyId() gives a non-reversible tag of the installed key, so a
passphrase change can be told from a re-unlock with the same one.
replace() stays a synchronous wrapper with the same result. A failed
INSERT is now logged.

The thread grid is inert during a benchmark, but the -/+ buttons and the
count field still took input: a click changed the shown and saved count
while the benchmark owned the miner's (before the previous commit it
also restarted xmrig at that count and spoiled the measurement). The
buttons and the field are now disabled until the benchmark ends.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Every thread-count change on the Mining tab saved settings.json and,
with a miner running, stopped and restarted it: xmrig re-inits its
RandomX dataset and reconnects to the pool, seconds of lost hashing
each time. A drag across the grid did this once per tile crossed (up to
~24), with a "Starting pool miner" toast each; every -/+ click or Enter
did it again.
The tab now hands each pick to the App, which puts the newest in
settings at once and applies it when the input settles: on drag
release, or 0.5 s after the last click, even if the Mining tab was left
in the meantime. The header, RAM estimate and tile fill still follow
the drag live.
- Pool: the restart is decided on the mining-control thread, after every
earlier start or stop has run. It never starts a miner the user
stopped, is a no-op when xmrig already runs at that count, and is no
longer silently skipped when the pick lands in another restart's stop
window (which left xmrig on the old count).
- Solo: one setgenerate per gesture. A pick made while one is in flight
now waits for it instead of being dropped (another stale count).
- Clicking the tile that is already selected does nothing; it used to
save settings and restart the miner.
- With idle thread scaling on, the grid no longer snaps back to the old
count while a pick is on its way to the miner. A pool auto-balance
restart keeps a count still queued.
- Idle thread scaling changes the pool count through the same retarget.
Its correction after a start compares with the count last requested,
not the xmrig API's lagging report, so it comes about 1 s in instead
of after the first API report (3-5 s).
- A retarget whose pool config no longer validates shows the same error
and stops the miner, as the old stop-then-start did.
- While a benchmark runs a pick is saved, but the miner change is
dropped: the benchmark owns the count until it ends.
A crash within 0.5 s of a pick, or mid-drag, loses that pick; every
clean exit saves it.

The requested thread count is written by generateConfig() on the
mining-control thread and read on the UI thread (the thread-grid sync
under idle thread scaling, the pool auto-balance restart) without any
synchronisation. The write also stored the unclamped count first and
clamped it afterwards, so a reader could see more threads than cores.
It is now an atomic, set by one store of the clamped value.

Settings::save() and WalletIndex::save() ran the atomic write (temp
file, fsync, rename, directory fsync) on the UI thread: on every
preference change, and for wallets.json after every address-scan pass
whose wallet metadata changed, i.e. repeatedly during sync, when the
disk is busiest. Each took milliseconds to tens of milliseconds, and
seconds under heavy disk load.
The JSON is still built on the caller; the write is queued on an
App-owned CoalescingWriter, latest wins per file, one write at a time.
- After a fund- or security-critical setter (seed-migration stage,
encryption pending, PIN enabled, active wallet file, wizard completed)
the next save still waits until the file is on disk, so e.g. the
sweep-submitted marker is durable before the sweep is broadcast. A
failed durable save keeps the next one durable.
- Saves before the writer is attached (the upgrade re-save at startup),
and in tests and tools, stay synchronous.
- main() flushes the queue (at most 3 s) before and after
App::shutdown(), before the single-instance lock is released, so a
relaunch never reads a stale settings.json.
A kill or power loss right after an ordinary save can now lose that
last preference change; the previous file stays intact. WalletIndex
saves report "queued" rather than "written" (no caller reads it). On a
wedged disk, exit can wait up to 2 x 3 s longer, inside the 15 s
watchdog.

Six sliders (noise opacity, UI opacity, window opacity, chat font size,
chat poll rate, contacts list scale) rewrote settings.json, with its two
fsyncs, on every frame the value changed: 60-300 durable writes per
drag, at 1-4 ms each on NVMe, 3-20 ms on a Windows SSD, 20-60 ms on a
HDD and seconds while dragonxd is busy on the disk.
The value still applies live and is kept in Settings for the per-frame
readers; settings.json is written once, when the slider is released, as
the blur and font-scale sliders already did. A drag cut off before its
release (a dialog closed mid-drag) is persisted by the next save or at
exit.

On Linux and macOS openUrl/openFolder spawned xdg-open/open and waited
for it on the UI thread: 50-300 ms per click where the opener forks and
exits, and on generic xdg-open sessions (sway, i3, WSLg, ...), which run
the browser or file manager as xdg-open's foreground child, the window
froze until the user closed that app. The opener is now left running
and a detached thread reaps it; the click returns at once.
Its stdin, stdout and stderr go to /dev/null again. That redirect was
lost in the switch to posix_spawnp, so a text-mode browser fallback
could take over the wallet's terminal.
The result now means "launched" rather than "exited 0" (no caller reads
it), and a non-zero opener exit is reported on stderr instead of in the
debug log. Windows (ShellExecute, which never waited) is unchanged.

On Linux and macOS the lock file was opened without O_CLOEXEC, so
xdg-open and the browser it starts, dragonxd and xmrig all inherited it.
A clean exit unlocks explicitly, but after a crash or kill the lock
stayed held for as long as any of those children ran (indefinitely with
"keep daemon running"), and the wallet refused to relaunch. The fd is
now opened O_CLOEXEC; nothing else changes.

On Windows writeFileAtomically wrote the temp file through std::ofstream,
whose CRT handle is inheritable. xmrig and the hidden helper commands
(where, nvidia-smi, xmrig --version) are started with handle inheritance
on, so one started during a save kept "<file>.tmp" open without delete
sharing, and every later replace of that file failed for as long as the
child ran: hours while mining, with settings saves quietly not landing.
The flush then reopened the file with share mode 0, so it was silently
skipped whenever AV or the search indexer had the file open, and a
replace refused by them just failed.
- Windows: one CreateFileA handle, not inheritable, writes and flushes
the temp file; the replace is retried up to 4 times (20+40+80+160 ms)
on access-denied, sharing or lock violations, where it used to fail.
- Linux/macOS: the temp file and directory fds are opened O_CLOEXEC, so
a dragonxd or xmrig fork+exec doesn't inherit them.
A later commit moves settings writes to a background thread, which makes
every one of them concurrent with those spawns. The vault, the exports
and DRAGONX.conf use the same function and get the same fix.

hasPendingRPCResults() becomes hasPendingBackgroundResults(): the one
check the idle loop makes, every <= 200 ms, for work that finished on a
background thread and still has to be applied by update(). Lanes added
later put their term there. It still covers only the two RPC worker
lanes; no behaviour change.

One background thread for blocking write jobs, for the settings.json /
wallets.json saves and the tx-history snapshot that later commits move
off the UI thread. Jobs are keyed (a file path, "tx-history"):
- a submit for a key that is still queued replaces that job and keeps
its place in line (latest wins);
- keys run first in, first out, one job at a time, so two writes of one
file never overlap and an older snapshot never lands after a newer one;
- submitAndWait() blocks until that job (or a newer one for the key) has
run and returns its result, for writes the caller needs on disk;
- flush() waits with a bound; stop() runs everything queued, then joins;
- the thread starts on first use and sleeps when idle; with no thread
(none could be created, or after stop()) a job runs inline.
persistFileAtomically() routes Platform::writeFileAtomically through a
writer, or writes synchronously when there is none. Nothing uses it yet.

"Keep in each address" posted one task that called z_mergetoaddress for
every batch of every address back to back; each call is a whole-wallet
scan under cs_main, and the daemon runs the ops one at a time anyway.
It is now an App-owned services::ConsolidationRun:
- one RPC at a time; the next merge only after the previous batch left the
queue and a gap as long as the last call took (2-120 s);
- pauses while the node syncs, the wallet is locked, a send of ours is in
progress, or another wallet scan is running;
- failures classified: nothing that may have queued is ever resent; a
breaker stops after 3 dead addresses or 3 failed ops in a row;
- each merge is charged to the scan budget; one re-read and one forced
balance at the end;
- it keeps running when the dialog closes: a status-bar chip, a run view
with progress, the wait reason and a Stop button.
The "Into one" merge can no longer be confirmed twice while its call is
in flight. fake_dragonxd gains FAKE_SCAN_SECS, FAKE_MERGE_SERIAL and
FAKE_MERGE_FAIL.

A z_sendmany submit set off a burst of wallet scans before anything had
changed. Ops now re-read the wallet when they finish, by who started them:
the user's sends and dialog ops get a re-read plus one forced balance once
none of their ops is pending; client auto-shield re-reads unforced; chat
messages and splits refresh only the chat note view. A pending send no
longer forces scans, and chat txids no longer enter the tracked-send set.
Chat ingest skips stored messages before decrypting and caches
undecryptable ones per identity. The inbox scan runs when getwalletinfo's
txcount changed (a cheap probe, at most 2% duty) or a cost-scaled safety
net is due; the note-buffer scan runs on need. Both are admitted by the
scan budget, on a steady clock. The chat payer comes from a per-address
view of verified notes, with debits re-applied across in-flight scans;
splits are sized to one payer and only when they can refill the buffer.

- Connect gate: after the node starts answering, wallet scans wait until the
lock state is known and the node knows its tip (or the wallet has fewer
than 500 transactions), at most 20 s. A node already behind latches the
sync profile from the connect's getinfo. Meanwhile a list-only pass keeps
the address list and the cached history up, and the session's first
balance and per-address balances are read once even while catching up,
so the wallet shows its last-synced values instead of 0.
- Background: minimized, hidden, or covered without focus (3 s debounce,
any input cancels) polls only the chain state every 15 s. Wallet scans,
the mining poll, price, nudges and auto-lock interaction tracking pause;
auto-lock now fires while minimized. Leaving a held profile marks every
timer due again.
- Tab entry marks the timers due instead of forcing scans; a stale list or
a never-loaded history still loads on entry.
- The scan entry points own the hard gates, failed enumerations keep the
previous lists behind a retry hold, and failed balance calls never
overwrite known balances with 0.

The balance, address scan, history and probe were throttled one by one at
10% each, which added up to 30-40% of dragonxd's cs_main with all of them
due. services::WalletScanGovernor runs one wallet scan at a time across
both RPC lanes and keeps one shared quiet clock at 15% of wall-clock (cut
when the node is behind). Waiters are served first in, first out, with a
head start for what the page shows and a starvation floor of max(30 s
visible / 900 s hidden, 15x the stream's cost). Explicit work (a dirty
set, the user's send, a first load) is never refused but is charged.
Routine scans run only when the tip, the mempool size (getmempoolinfo:
no cs_main) or a wallet-mutation epoch changed since their last good scan,
or a safety sweep is due. Pages that don't show the balance poll it at
most every max(10 min, 50x its cost) (2 min with client-side auto-shield);
coming back into view with an old value fetches it at once. The staleness
badge counts from the last poll that confirmed nothing changed, and hides
while the budget holds the balance within its guarantee.

Every block re-ran z_listreceivedbyaddress for every z-address (O(wallet)
each, under cs_main) and a whole-wallet z_listsentbyaddress. On a 40-address
wallet that was ~80% of wall-clock. The history now advances in passes:
- an address is rescanned when it is stale by a number of blocks scaled to
its measured cost (8 to 500), never-scanned and hinted addresses first
(a hint: z_listunspent shows a note the history doesn't);
- z_listsentbyaddress covers only the blocks since the last good sweep
(+100 reorg margin); the whole-wallet sweep runs once per connect, with
a 10 min / 1 h / 6 h backoff after real failures;
- listtransactions pages are sized from last time, and an unchanged tip
reuses the transparent rows;
- found-but-unenriched txids carry over as a backlog; only -5 is a
definitive "not ours" for z_viewtransaction;
- between blocks, a cheap recent poll plus a one-address probe.
Duty model for a 40-address wallet at 10 s per scan: ~9% instead of ~80%.

The Core poll ran z_gettotalbalance twice (minconf 0 and 1), each a whole-
wallet scan under dragonxd's cs_main. The spendable (minconf=1) call now
runs only after the display call succeeded, and only when something is
unconfirmed or pending or the exact total moved: about 95% of polls make
one scan instead of two. A forced post-send balance can no longer be lost
to a refused enqueue, and pending-send debits aren't re-applied each tick.
z_getoperationstatus is filtered to our opids with its real argument form
([[id,...]]; the old ["id"] was rejected), falling back to the unfiltered
call if a daemon refuses the filter. The Shield/Merge dialog's own polls
are filtered and session-guarded too, and finally reach Done; the dead
RPCClient wrappers are deleted.
The Merge/Consolidate scope scan becomes a tested state machine: one scan
at a time, failures latch behind a Retry button, only "node not ready"
retries by itself (10/30/60 s, at most 3), Lite never scans. Its 120 s
calls are maintenance calls: every main-thread disconnect aborts one in
flight first, so a lifecycle action no longer freezes the UI behind it.
An aborted merge that was already sent says it may still go through.

Lite opens an encrypted wallet locked, but the model saying so arrives
a moment later. The first seed export therefore failed with "locked"
and disabled chat for good, so encrypted Lite wallets never got chat.
- While the wallet is locked, a failure recorded before the lock was
seen is cleared, so provisioning runs again after the unlock (like
lockLiteWallet()). Nothing is retried while locked: that branch
returns before any RPC or backend call.
- Lite waits for the first model's lock state before exporting the
seed.

- The refresh-model mapper marks the encryption state known when the
backend reports it. The wallet tabs wait for that, so every Lite
launch sat behind the loading overlay until the 15 s "assume
unencrypted" fallback.
- Each 2 s refresh skips the backend's `info` (a fresh TLS connection
and GetLightdInfo, only a fallback for the chat tip, which the
explicit height call already provides) and the gateway's `height`
(replaced by that explicit call, which runs after the sync commands
so it sees the newest block).

checkIdleMining ran every frame: an X11 idle query and, with GPU-aware
idle detection, an nvidia-smi launch on the UI thread per frame.
- The check runs once a second, since its decisions work on a seconds
scale (the idle delay is tens of seconds or more). A miner it started
or scaled up still yields on the first frame that sees the user back:
that path skips the gate, because frames can be seconds apart while
the app idles.
- The GPU is probed only when input is idle and the result can change
a decision, at most every 5 s, with hysteresis (busy at 10%+, clear
below 5%) so a GPU hovering near 10% can't keep restarting the miner.
- Thread scaling returns early when no miner is running or a toggle is
in flight.

The Market tab calls the exchange-list, price-history and candle
fetches every frame, so a failed fetch (offline, rate-limited, a
venue's API down) was retried on the very next frame, ~20 requests a
second.
- util::FetchBackoff: 30 s doubling to a 10 min cap, +/-20% jitter.
The exchange list, the price history (a partial result counts as a
failure) and the per-pair candles each back off on failure.
- Candle backoff is per pair. Switching to another pair still loads at
once, a failed refresh keeps the on-screen pair's last candles, and
switching back to a pair that is backing off shows the aggregate
chart rather than the previous pair's candles.
- The Market tab's refresh button retries at once (at most every 5 s).
A price fetch (60 s timer, no backoff) that succeeds after failing
means the network is back, so it lifts all three backoffs.
- A partial price history no longer marks the chart loaded: with no
fetch timestamp, the 30-minute reload gate measured system uptime
and blocked retries for the first 30 minutes after boot.
- The exchange list goes through httpGetString (TLS verified, size
capped) with short timeouts (5 s connect, 12 s total, as it runs on
the shared RPC worker) instead of its own curl code. A failed fetch
is retried; it used to be tried only once per session.

- Explorer: the tip check runs every frame the Explorer tab is open,
and it read both tip rows and rewrote them each time (two autocommit
WAL writes per frame). A steady tip is now kept in memory and skips
SQLite. A new tip writes both rows in one savepoint, so a crash
between them can't pair a new height with the old hash. A test
checks that 100 steady checks write nothing.
- Console: while the daemon was in the Error state the Console tab
added its error line on every poll, i.e. every frame, re-laying out
the whole buffer each time. It prints once per error now: on entering
Error, when the message changes, or after another crash
(EmbeddedDaemon::getUnexpectedExitCount(), never reset). setState
writes the message before the state, so a reader that sees Error sees
that error's message. The stray " ===" suffix is gone.
- perf.log: the profiler appended a block every 300 frames on every
run and never rotated the file (tens of MB a day for a wallet left
open). It is now off unless the app starts with DRAGONX_PERFLOG=1;
otherwise its zone hooks are near no-ops.

Restoring or un-maximizing the window called refreshNow(), which wipes
the history-scan progress and re-scans every z-address (a
z_listreceivedbyaddress per address, each holding cs_main). The Peers
tab's refresh button did the same, and holding F5 auto-repeated it.
- Window restore no longer forces a refresh; the regular timers catch
up (skipping the daemon-output backlog stays).
- The Peers refresh button refreshes peers only.
- F5 ignores key repeat. An explicit F5 or History refresh still does
the full re-scan.

A send stays tracked until z_viewtransaction shows an outgoing output.
Shields, merges/consolidations and chat note splits pay only the wallet
itself, so they never showed one. They stayed tracked for the whole
session and forced a full history refresh past the scan throttle on
every tab.
- A tracked send whose view has no outgoing output is retired once it
is mined (1+ confirmations) or conflicted.
- Tracked sends are enriched first, and reaching the per-cycle view cap
no longer ends the loop, so the cap can't starve them.
- Backstop: a tracked send still unsettled 20 blocks after it was added
(expired, dropped from the mempool) stops being tracked.
- Tracked sends are cleared on disconnect: they belong to that
connection's wallet.

Connected-but-locked fell through to tryConnect() on every Core tick
while the lock screen sat idle: new sockets, getinfo and getwalletinfo,
a forced address scan, a CoinGecko fetch and a wallet-index rewrite.
Its wallet scans also held cs_main ahead of the user's
walletpassphrase.
- While locked, poll chain state only (refreshCoreData without the
balance). That keeps the sync height current and the 3-strike
lost-connection check armed, so a node that exits while locked is
still restarted. Pool mining keeps the lock screen down, so while it
runs the throttled balance, the peers and the lock state (for an
unlock done in the Console tab) keep refreshing too.
- Warmup polls count refused/reset connections toward the
lost-connection check, so a node that died during warmup is
restarted instead of leaving the loading or lock screen over it.
- The wallet salvage/degraded detectors run at connect and again when
warmup ends: for encrypted wallets they relied on the repeated
tryConnect.
- restartDaemonAfterEncryption records the wallet as encrypted and
locked itself (the wizard's deferred path never did), and marks the
main client disconnected so the reconnect path picks up the restarted
node, aborting any in-flight call first.

While theme effects were on (the default) the main loop drew every
frame it could. Where vsync is off (offscreen, some drivers, remote
sessions) an idle wallet spun at ~3,000 fps, 88% of a core; with vsync
it still drew every refresh. Frames are now paced by what needs them:
- full rate while there is input, a held key, a window appearing or
settling, a smooth scroll or the UI sweep;
- ambient (30 fps focused, 10 fps unfocused) for theme effects, the
acrylic backdrop, avatar animations and notifications;
- progress (10 fps focused, 4 fps unfocused) for UI that changes
without input. The updater and bootstrap downloads, console
commands, lite-wallet operations, seed migration, the loading
overlay and the lock-screen countdowns ask for it with
material::RequestProgressFrame();
- otherwise idle, as before: wait for events, with a housekeeping wake
every 2 s (5 s unfocused).
A software frame cap (0.9x the display refresh) bounds the loop where
vsync is off, and hidden, occluded or minimized windows get no ambient
frames. Reduce Motion freezes the theme-effect clock
(ThemeEffects::setMotionFrozen), so it needs no ambient frames either.
The displayed-balance roll goes through one clamped StepDisplayLerp
(balance_lerp.h). An idle-length frame pushed dt*speed past 1, so the
roll overshot, and under Reduce Motion's speed of 999 it diverged to
inf/NaN. The classic layout had its own copy of the old code.
Idle CPU, Lite build, offscreen (no vsync): 88% -> 5% of a core with
effects on, and 91% -> 3% with effects saved off (with the previous
commit).

Low-spec mode, theme effects, blur, UI and noise opacity and the
console scanline reached the live effects state only once the Settings
page or the first-run wizard was opened. "Effects off" and low-spec
therefore reverted at every launch, and the animated defaults kept the
main loop busy (91% of a core on an idle Lite wallet whose effects were
saved off).
- App::applyVisualSettings(): one low-spec-aware path from the saved
prefs to the effects state, used at startup (after the skin, since
setActiveSkin reloads the effect config), by the low-spec hotkey, the
wizard and the Settings page.
- Low-spec stays a runtime-only override. The Settings page shows the
overrides but persists the real prefs from its snapshot, and opening
it under low-spec no longer turns theme effects and blur back on.
Unticking a low-spec in the wizard that was loaded rather than ticked
there now restores the saved prefs.
- Theme effects on/off always pairs with reduced transparency (the
rainbow, shimmer and glare layers), as at startup and in the hotkeys.
- kAcrylicMaxBlur moves to imgui_acrylic.h, so startup clamps blur
values saved in the old 0-4 range the way the slider does.

Logic timers advanced by io.DeltaTime, which update() clamps to 0.25 s
so animations don't jump after a pause. That matched real time only
while the main loop rendered continuously: with frames seconds apart, a
timer fed the clamped delta runs up to 8x slow. Affected: the refresh
scheduler, the seed-migration poll, the chat fast scan, the encryption
check, the loading and shutdown timers, the lock-screen countdowns, the
Settings debug gate and the mining benchmark.
- App::logicDeltaTime(): steady-clock seconds since the previous
update(), capped at 6 s so a sleep/resume fires each timer once
instead of replaying the gap. Visual interpolation keeps the clamped
io.DeltaTime.
- The refresh timers tick before the RPC results are drained, so a
hold that a callback arms (the connect-retry backoff) starts fresh
instead of being charged the gap before it existed.
- The shutdown timer is measured from shutdown_start_time_:
beginShutdown runs from SDL event handling, so an accumulated delta
would count the idle gap before the close request.
- The lock-screen error and lockout countdowns subtract only the time
since they were armed: a failed unlock arms them from an RPC result,
which can land on the frame that ends an idle gap.

This branch's only commit (424954f) is already on dev as an identical patch
(fae8b20, merged in 1151141; git cherry reports it as equivalent). A normal
merge conflicts only where dev has since moved past it: the NotoSansCJK
subset was rebuilt again as a superset that still contains the FAQ glyphs,
and app.cpp and node_status_banner.h changed later. This merge records the
branch as integrated and keeps dev's content unchanged.

Every fix on this branch already reached dev through the port in bcee4bf
("apply audit remediations to dev"), adapted to dev's code and in several
places hardened further (0600-at-open xmrig config, strict 127.0.0.0/8
loopback check, metadata cap centralised in httpGetString). F14-1 and F8-2
were fixed independently on dev. All 10 conflicting files therefore resolve
to dev's side, which drops nothing.
The one thing dev lacked is the F14-1 regression test: a quoted empty
console argument ("") must be kept rather than shifting later positional
RPC params. This merge brings that test in.

Users who keep funds apart under different labelled addresses can now
shed notes (smaller wallet, faster scans/witness rebuilds) without the
funds being merged into a single address.
- Merge/Consolidate dialog: "Where should the funds go?" - Into one
address (unchanged) or Keep in each address. The latter lists shielded
addresses with 2+ spendable notes (label, note count, amount;
too-small ones disabled) and merges each address's notes back into
that address with z_mergetoaddress [addr] addr. Addresses with more
notes than the batch size get several batches (the daemon locks a
batch's notes before returning, so calls take disjoint notes); the
dialog suggests a second run after those confirm. Per-address
progress; ops keep running if the dialog is closed. The Consolidate
(wallet-size) preset opens in this mode; Merge keeps "Into one".
Shielded only: a transparent address can't take a merge's output.
- services/note_consolidation: groupSpendableNotes, worthConsolidating,
estimateBatches, consolidateInPlace (pure; driven by a merge-call
function), with unit tests against a stand-in following dragonxd's
rules.
- fake_dragonxd: optional note wallet (FAKE_WALLET_NOTES,
FAKE_MERGE_SECS) with z_mergetoaddress and its operations.
- i18n: 17 new keys in all 8 languages; CJK subset rebuilt.
- UI sweep: modal-consolidate target.

Follow-up to 5246898. A transparent address only ever receives mining
rewards on DragonX (private chain), so:
- One explainer ("Receives solo-mining rewards only - the network rejects
payments to it. Rewards are shielded automatically once they mature.")
on the Overview row hover, the Receive picker hover, the Receive card
and the Validate Address result (now typed "Mining address
(transparent)").
- Receive: a selected mining address shows the explainer and a "Use a
shielded address" button (creates one if none exists) instead of the
payment request, and a "Not for payments" panel instead of a QR code.
The default selection prefers a shielded address; the "All" filter
hides empty mining addresses unless solo mining or marked as a mining
address; the filter reads All / Shielded / Mining.
- Request Payment: no transparent section, never prefilled with one.
- Overview: no "Mining - Mining" tag on a marked transparent row.
- FAQ: address answers rewritten; the send and memo answers no longer
imply you can pay a transparent address. All 8 languages.
i18n: 4 new keys, 6 FAQ answers updated in place, 2 dead keys removed,
CJK subset rebuilt. UI sweep: receive-mining-address and
modal-validate-mining targets.

DragonX is a private chain (-ac_private=1): consensus rejects any
non-coinbase output to a transparent address, so a t-address can only
ever receive mining rewards, and its coins can only move to a shielded
address. The wallet treated them like ordinary recipients.
Block paying one:
- Send: a transparent recipient shows "Mining address - can't be paid"
and disables Review Send (tooltip explains; ask for a zs... address).
Typing, paste, contacts and payment URIs all go through this field.
- Overview drag-to-transfer: a mining-address row is never a transfer
target (it only reorders).
- Pool payout must be shielded (pools pay with ordinary transactions):
field tooltip, disabled Start button and the start check say why.
- isValidRecipientAddress() is now shielded-only; new isDragonXAddress()
and classifyRecipient() (Shielded / MiningOnly / Invalid).
Call them mining addresses:
- Overview: "Mining rewards" card (amber "Not yet shielded" when there
is a balance; hover explains; click opens the Shield dialog), "New
mining address" button with a tooltip, rows typed "Mining".
- QR / label dialogs, portfolio filter, contact badge ("Mining only"),
Receive notifications.
i18n: 17 new keys in all 8 languages, 12 dead keys removed, CJK subset
rebuilt. Tests: recipient classification, translation completeness.
UI sweep: new "send-mining-recipient" target.

S12 - our node across sessions:
- The node the wallet launches is recorded in <datadir>/obsidiandragon-
dragonxd.pid (pid + process start time + exe). A later session that
finds it still running (after "Leave running" / keep_daemon_running)
stops it gracefully on quit and waits for that exact process (no time
limit, "Leave running" offered); never signals or kills it. A reused
pid or a reboot never matches; stale records are deleted.
- stop_external_daemon is now honoured when this session only connected
(no controller); it was ignored.
S13 - the node's own log on every platform:
- No -printtoconsole on Linux/macOS: the node writes its timestamped
debug.log (which outlives the GUI) and we tail it next to the stderr
pipe. Tail path from the datadir or the isolated override (Windows had
%APPDATA% hard-coded, wrong for migrate-to-seed starts).
- After the node shrinks debug.log at startup, resume at this run's
banner instead of re-reading the old run's tail.
- A node we didn't launch (left running, or found running) feeds the
busy tracker from its debug.log, tied to the live process (our record,
or POSIX hushd.pid) and only from lines it wrote. A GUI attaching to a
node mid-rebuild now says "Node busy: rebuilding note witnesses" and
asks before stopping it.
- A start that only finds a running node no longer resets the tracker;
a found busy node shows the busy overlay at once.
S14: launch our node with -rpcthreads=16 unless DRAGONX.conf sets it.

Every operation that stops the node (restart, rescan, repair, delete
chain data, reinstall, bootstrap, wallet switch/adopt/restore/rebuild,
wizard restart, encrypt, decrypt) now:
- refuses up front while the node is rebuilding witnesses or has not
answered for 30s, with a "try again when it's done" warning, and sends
no stop;
- goes ahead only once the node's PROCESS has exited, not its RPC port.
A stop that doesn't finish within 120s cancels the operation (warning;
a cancelled rescan/repair disarms its flags); nothing is started over
the old node, chain data isn't deleted, wallet.dat isn't swapped.
Specifics:
- stopDaemonForWalletSwitch() no longer reports "stopped" when the app
is quitting (adopt could swap wallet.dat under a live node).
- Decrypt waited a fixed 3s after "stop" before renaming wallet.dat; it
now waits for the process to exit, and scrubs the key export if not.
- Bootstrap waits for the process before cleanChainData and stops the
node through the stop routine instead of the shared RPC client.
- StopScope::Connected lets switch/reinstall/decrypt stop an adopted or
external node through the same never-kill routine.
- A bounded stop that can't reach the node (a foreign node refusing our
credentials) gives up after 5s instead of 120s.
- macOS: isDaemonProcessRunning() checks processes (libproc), not the
RPC port.
- rpcBusyWhileAlive() also reads the busy gate: since the gate, the
first timeout usually lands on another lane and the 30s clock never
started (also weakened the quit prompt for a silent rebuild).
- Notifications render during the first-run wizard.

A node rebuilding note witnesses for an hour was shown as "Starting
DragonX node... Launching dragonxd", which invited closing it.
- Overlay, a new NodeBusy banner and the status bar now say what the node
is doing (rebuilding witnesses / catching up on blocks / up but not
answering), with the elapsed time and Phase-1 block progress. A rebuild
during startup warm-up replaces the stale "-28 Activating best chain"
text, and the overlay re-applies its text once a second instead of only
on a connect attempt (30s apart while the node is busy).
- Quit prompt: elapsed time, "Keep node running & quit" is the default,
"Stop anyway & quit" becomes "Stop node & wait" (it no longer kills).
- A reinstall skipped because the node is still running now notifies.
- Status bar: don't repeat the warm-up status on the right, and don't
print "Connected" there in non-English locales.
- i18n: 31 new keys in all 8 languages; 10 dead force-quit/old-modal keys

- Tests: chooseDaemonStatus, NodeBusy banner priority, and every new key

dragonxd serves RPC with 8 workers and a 16-deep queue. While a witness
rebuild holds cs_main, every request needing it waits, and a request the
client gave up on keeps its slot. The GUI kept polling and re-probing
until all 24 slots were its own abandoned requests (even stop was then
refused), treated the busy node as lost (tearing down the wallet state),
and retried connect at frame rate on some pages.
Busy gate (src/rpc/rpc_busy_gate.h), enforced in RPCClient::performCall
for the shared rpc_ / fast_rpc_:
- the first reply timeout or queue-full refusal marks the node busy;
from then on nothing needing cs_main is sent (calls fail at once with
the new RpcFailureKind::Deferred). stop, help and getrescaninfo are
lock-free in dragonxd and always go through
- one canary getinfo with no client timeout waits on its own client and
thread; its answer clears the gate and triggers an immediate refresh
(queue-full: retried after 2..30 s; no answer: back to normal handling)
- the timer dispatch skips Core/Tx/Addresses/Peers/chat/mining/opid and
connect attempts while busy
- the 3-strike teardown counts only failures that put the connection in
doubt, never busy ones; no balance scans follow a busy chain-info call
Reconnect storm: retries were armed with setTimer(Core, kCoreDefault - 1),
i.e. "4 s elapsed", which against Overview's 2 s interval meant every
frame. RefreshScheduler::deferFor() is an absolute hold, and
ConnectRetryBackoff picks the delay by failure kind (not listening
1/2/5 s, queue full 2..30 s, busy 30 s, else 4 s).
Measured against the fake daemon: abandoned requests during a rebuild
went from ~24 (every slot) to at most 2, with no teardown and recovery
when the rebuild ends; a saturated queue sees about one canary per
back-off step instead of ~190 requests/s.

The one-time "back up your seed phrase" nudge only stopped probing on a
success or the exact "not derived from a mnemonic" error. Any other
answer re-armed it for the next frame, so a daemon without the RPC
("Method not found", e.g. the older bundled binary) was sent
z_exportmnemonic at frame rate: ~2,300 requests/s against a test node.
Chat identity setup re-posted its fetch on the next frame after a
transient failure in the same way.
An inconclusive nudge probe now waits 5 minutes before the next; a
transient identity-fetch failure waits 10 seconds.

- getrescaninfo takes no lock in dragonxd (it only reads wallet fields),
so the stub no longer holds it behind cs_main. Holding it there made
the GUI's rescan-progress poll look like an abandoned request every
30 s during a simulated rebuild.
- a `methods` event lists the 10 most-requested JSON-RPC methods with
counts (alongside `stats`, and at exit): what the GUI is polling.

Quitting during a witness rebuild is supposed to ask before stopping the
node, because a stop throws the rebuild away and a killed node replays
and redoes it. The guard almost never fired:
- it returned false for any daemon >= v1.3.0, on the false premise that
v1.3.0 checkpoints a rebuild (it does not; nothing survives a kill)
- it read a 16 KB debug.log tail and compared the last progress line with
the newest line, so any unrelated line during the rebuild's silent
second phase turned it off; and on POSIX that file is stale
- daemon_version, which the bypass needed, is zeroed when a busy node
drops the connection
Now a DaemonBusyTracker (src/daemon/daemon_busy_detect.h, pure) follows
dragonxd's own markers in order: rebuilding (Phase-1 / legacy markers,
ended by the completion line, an abort line or the next UpdateTip) and
replaying (Activating best chain ... Done Loading), reset by a new banner
or "Shutdown: done". It is fed from the owned output on the UI thread,
including the backlog skipped after a restore. The quit guard prompts
when the quit would stop the node and it is rebuilding, or has been
alive but only timing out / refusing as busy for >= 30 s. A replay alone
never prompts: stopping it is safe. The stop loop uses the same signal
to never offer Kill during a rebuild.
Also:
- daemon output offsets are absolute, so a reader that falls behind a
trim of the 1 MB buffer no longer skips new output (which could hide a
start or end marker)
- a quit deferred while minimized restores and raises the window, and
the wizard renders the prompt, so it is never waiting unseen
Verified live with the fake daemon: quitting mid-rebuild now shows the
prompt for a v1.3.0 node and leaves the node alone; a silent busy node
prompts after 30 s.

Holds cs_main like a witness rebuild but logs no rebuild markers: a node
that is busy while its output says nothing (an external node, or a
rebuild path that prints no progress), for exercising the GUI's
"busy but alive" handling.

Closing the wallet sent "stop" at most twice, gated on a getinfo probe
that needs the daemon's cs_main, then killed the node after 20 s (Windows)
or 30 s (POSIX) whether or not stop had arrived. A node busy with an
hour-long witness rebuild therefore never got stop, was killed mid-
rebuild, and replayed everything since its last flush on every start.
Delivery (src/daemon/stop_delivery.h, RPCClient::open/trySendStop):
- stop goes over a dedicated client with no probe, so it never waits on
rpc_'s lock or a cs_main-bound getinfo
- every attempt is classified, and StopDeliveryPolicy decides the next:
Accepted / 503 = delivered; Queued (reply timeout) is resent at most
every 30 s; QueueFull / not listening are retried every 1.5 s; a
refusal after we were heard means the node is shutting down; a 401 on
our own node tries the next credential source
- POSIX: a group SIGTERM goes out as soon as an attempt fails, which
bypasses the HTTP queue entirely
Waiting (DaemonController::executeDaemonStop, pure, virtual-clock
tested):
- never kills on its own. Quitting waits as long as the node needs; the
shutdown screen offers "Close wallet — leave node running" after 3 s,
and "Kill node (unsafe)" (confirmed) only once stop was delivered and
the node showed no CPU/I-O progress for ~10 min outside a rebuild
- other callers (restart, rescan, reinstall, switch, ...) wait up to
120 s, let go once the app starts quitting, and keep watching a node
that is still running; wallet switch refuses to go ahead then
- EmbeddedDaemon gains stop-session primitives (beginStop,
pollOwnedProcess, signalGracefulStop, forceKillOwnedProcess,
ownedResourceUsage over the Linux process group / Windows handle,
endStop) and only one stop session runs at a time
- the Force Quit button and its stall heuristic are gone; "Leave
running" aborts a pending stop attempt and closes at once
Verified against the fake daemon with the real GUI: closing mid-rebuild
now delivers stop (or SIGTERM 2 ms after a queue-full refusal) and the
node exits cleanly after its rebuild, where it was SIGKILLed before. The
shutdown screen, its "Leave running" button and the idle Kill offer
(after ~11 min) were checked by screenshot. New strings are English-
only for now.

On Windows, stop() with no live process of its own looked up the first
"dragonxd.exe" by name and TerminateProcess'd it after the grace period:
an old node still shutting down (how an in-progress shutdown was killed),
a node on another datadir, or the user's main node. It was reached on a
lock-gated close, for an external node, after the tracked process had
exited, and from ~EmbeddedDaemon's stop(3000).
- Windows stop(): drop the by-name branch; with no tracked process it
logs and returns. findProcessByName is detection only.
- ~EmbeddedDaemon no longer calls stop(); it stops watching and releases
its handles. stop() returns whether the process exited on its own.
- SeedWalletCreator never sent its isolated node an RPC stop, so on
Windows that node was always force-killed holding the wallet.dat it
had just created, and the stack object's destructor could then kill
the main node by name. It now stops the node over the node's own RPC
on every path. A node that still had to be force-killed fails the
creation (seed wiped; nothing has been swept into it yet), so an
uncleanly closed wallet is never adopted.
- Reinstall waited only for the RPC port, which closes long before the
process exits (locked exe on Windows, held datadir lock everywhere).
It now waits for the process to exit and otherwise aborts without
touching the binaries or starting a second node.
- Linux isDaemonProcessRunning also matches /proc/<pid>/exe, so a node
whose main thread is already renamed "hush-shutoff" (still holding the
datadir lock) counts as running.
Tests: a Windows real-process test (a fake dragonxd.exe on an isolated
datadir survives stop() and the destructor), a POSIX test that the
destructor leaves the process running, and the pure identity rule.
scripts/test-windows.sh passes the stub path to the Windows suite.

Every caller guessed what went wrong from what(): "Timeout" meant busy,
"401" meant auth, and warmup was code -28 or one of six substrings. A
non-JSON HTTP 500 lost its body, so "Work queue depth exceeded" read as a
bare "HTTP 500", and libcurl reports connect- and reply-phase timeouts
with the same code.
New header-only src/rpc/rpc_failure.h:
- RpcFailureKind (NotListening, ConnectTimeout, ReplyTimeout, QueueFull,
ShuttingDown, Unhandled, Auth, Warmup, AppError, Aborted, Other) and a
pure classifyRpcFailure(curl code, request-sent, HTTP status, JSON-RPC
code, plain-text body)
- formatHttpError keeps a short, printable plain-text body
- RpcError (moved here) stays "the daemon answered with a JSON-RPC
error". The new RpcTransportError means "no JSON-RPC answer": curl
failures and HTTP-layer refusals (401, 503, queue full, unhandled).
Keeping them separate matters: callers catch RpcError to mean "the
daemon said no" (chat identity's no-mnemonic fallback, seed export),
so a timeout must not be one. They now treat a queue-full 500 as
transient rather than as "no".
RPCClient:
- performCall tells the two timeouts apart with CURLINFO_REQUEST_SIZE
(0 = never reached the daemon; reset on every transfer, checked on
libcurl 7.81), and callRaw now shares performCall and the HTTP-failure
path.
- connect() decides warmup by the -28 code only, so a plain-text body
saying "Loading" can't pass for warmup, and records
getLastConnectFailureKind().
- "Connection failed" names the kind and is logged once, then every
100th repeat (one incident logged it 60k times).
- secret-bearing calls never echo a response body.
tryConnect's "401"/"Timeout" checks now use the kind, and
CoreRefreshResult carries blockchainErrKind/balanceErrKind for the busy
handling to come.

POSIX stop() set should_stop_, which made the monitor thread return
without reaping the child, and then polled the state-based isRunning(),
which stays true while the state is Stopping. So every Linux/macOS stop
waited out its whole grace period, sent SIGTERM, waited 10 s more and
SIGKILLed, even when the node had exited seconds earlier. Closing the GUI
with an idle node took ~30 s; a node still flushing at 30 s was killed.
- stop() joins the monitor first, then polls waitpid(pid, WNOHANG) on
a cached pid, so it is the only reaper and sees the exit at once.
- markStopRequested() (set by App::stopEmbeddedDaemon before the RPC
stop, and by stop() itself; cleared by start()) makes an exit that
lands before stop() runs a clean stop instead of a crash, on POSIX
and in the Windows monitor. crash_count_ drives auto-restart, and a
crash recorded before the request keeps its count.
- The SIGTERM -> SIGKILL escalation stays for now, but only fires for
a daemon that has really not exited. Replacing it with a wait policy
and an explicit user choice is follow-up work.
Verified against the fake daemon: an idle node that exits 3.4 s after
stop used to be SIGTERMed at +20 s and SIGKILLed at +30 s (GUI closed
in 30.6 s); it is now reaped as "exited cleanly" ~50 ms after it exits
(GUI closes in 4.0 s). New POSIX tests cover the clean exit, the early
requested exit and a graceful SIGTERM, each time-bounded so the old
code fails fast.

A Lite-configured tree builds ObsidianDragonLite and has no embedded
daemon, so any bin/ObsidianDragon left in it is a stale full-node binary

scripts/test-windows.sh cross-compiles ObsidianDragonTests.exe (and the
fake_dragonxd stub) with mingw into build/windows-tests, reusing the
toolchain and dependency sources from build/windows, and runs it from
WSL through Windows interop (or wine). All tests pass on Windows.
CMake:
- Windows forced BUILD_TESTING OFF in the cache to keep curl's tests
out, which also removed ObsidianDragonTests from every Windows build.
Hide it from curl with a scoped variable instead, and restore our
cache value afterwards (curl's cmake_dependent_option FORCE-writes
it). Windows still defaults to OFF, so release builds are unchanged.
- ObsidianDragonTests now depends on copy_langs: i18n.cpp includes the
generated embedded/lang_*.h, so a tree that builds only the tests
failed (latent on Linux too).
- Link the Windows system libraries the tests need.
Tests:
- testTmpPath/fixtureDir/removeTree helpers: no hard-coded /tmp, a
runtime fixture-dir override (the compiled-in path is a Linux one),
and best-effort cleanup that can't abort the suite.
- Close the explorer cache before deleting its directory (Windows
can't delete an open file).
- Compile out the address-book and wallet-index round-trips on Windows:
getConfigDir() uses SHGetFolderPath there, which no environment
variable redirects, so they would overwrite the real
%APPDATA%\ObsidianDragon files.

A scriptable fake dragonxd that reproduces, in minutes, the incident where
the GUI hard-killed a node busy with an hour-long witness rebuild:
- dragonxd's HTTP-RPC queue (8 workers + 16 queued, -rpcthreads /
-rpcworkqueue honoured): a full queue answers an immediate plain-text
500 "Work queue depth exceeded", and a request whose client gave up
keeps its slot until a worker reaches it
- a global cs_main held by a "witness rebuild" that logs the real
markers; every method except stop/help takes it
- warmup -28 with the daemon's allow-list, an optional startup replay
- dragonxd's shutdown order: stop (or SIGTERM on POSIX) unbinds RPC,
503s open connections, waits for the rebuild, then logs
"Shutdown: In progress..." / "Shutdown: done" and exits 0
Everything is appended to <datadir>/fake_dragonxd.events; a missing
"clean-exit" line means the process was killed. One portable C++17 file
(POSIX + Winsock), OFF by default (-DDRAGONX_BUILD_FAKE_DAEMON=ON), built
into <build>/fake_dragonxd/ so it can't shadow the real bin/dragonxd.
run-gui-with-fake.sh runs the GUI against it in a throwaway HOME.
Against master's GUI on Linux it reproduces the bug: closing during a
rebuild queues stop behind cs_main-blocked workers, then the GUI sends
SIGTERM and SIGKILL mid-rebuild, with no clean exit.

Bug-report fixes plus adversarial-audit follow-ups. Bumps full 2.0.1->2.0.2 and
lite 1.1.0->1.1.1.
i18n / fonts:
- Rebuild the NotoSansCJK subset with the glyphs the FAQ back-fill introduced
(什/么/门/做); Chinese FAQ titles rendered as "??" on zh (and ja/ko).
Transaction history (enumeration gaps):
- Surface outgoing shielded z->z sends via z_listsentbyaddress (listtransactions
and z_listreceivedbyaddress never report them).
- Surface z->t deshields by parsing z_listsentbyaddress transparentSends (which
z_viewtransaction does not expose); dedupe t->t against listtransactions.
- Key send-row dedup on address so equal-value multi-output sends aren't dropped.
Lite wallet (key safety):
- The async create/restore/open path the UI uses now applies the passphrase:
encrypt a new/restored wallet, unlock an existing one. It previously discarded
the passphrase, storing the seed/keys in PLAINTEXT (create/restore) or leaving
an encrypted wallet locked (open).
Migrate-to-seed (fund safety):
- Persist a sweep-submitted marker at broadcast so a resumed migration can't treat
a ~0 balance (an unconfirmed in-flight sweep) as an empty wallet and adopt (swap
wallet.dat) before the sweep confirms; best-effort locate routes to the confirm gate.
Sync / threading:
- Gate isSynced() on a peer-derived tip (tip_known) so a peerless node isn't reported
synced (Send against a stale balance); add a "no peers" status banner.
- Guard daemon_status_ with a mutex (monitor-thread write vs UI-thread read).
Tests: extends tests/test_phase4.cpp across all of the above; suite green.

Ship https://lite6.dragonx.is and https://lite7.dragonx.is as default
lightwalletd servers in both the Settings defaults and the connection-service
fallback list. Existing installs (whose saved server list predates these)
pick them up via a load-time merge that appends any missing default server —
safe because servers are hidden, never deleted, so a removed server isn't
resurrected. Consolidates the Settings default list into a single

Complete the de/es/fr/ja/ko/pt/ru/zh translations so every English source
key in i18n.cpp is now covered (2341 keys per language, 0 missing). Covers
the chat delete/block flow, the block-database reindex + wallet-recovery
prompts, node auto-shield status, the in-app FAQ (full-node + lite), the
daemon updater/version picker, the debug-options gate, and more.
Additive-only (no existing key changed). Printf format signatures preserved
and validated against i18n.cpp formatSignature; newlines, the "→" arrow, and
brand/technical identifiers kept verbatim. Terminology grounded on each
language's existing translations for consistency.

Derive the macOS BDB depends triple from the build arch + pass the BDB paths
to CMake, so the full-node mac release builds the wallet-rebuild helper on
Intel (x86_64) as well as Apple Silicon.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The macOS release path hardcoded aarch64-apple-darwin for the wallet-rebuild
helper's static libdb and — unlike the Linux/Windows paths — never passed
-DBDB_INCLUDE_DIR/-DBDB_LIBRARY to CMake. So on an Intel Mac the helper either
couldn't find libdb, or picked up macOS's SDK stub /usr/include/db.h (a DB 1.85
shim with no db_create) and failed to compile.
- mac_bdb_dir(): map the target arch to the depends triple (x86_64 ->
x86_64-apple-darwin, arm64 -> aarch64-apple-darwin; universal / unknown falls
back to the host arch).
- Pass -DBDB_INCLUDE_DIR / -DBDB_LIBRARY (when the vendored libdb is present) in
BOTH the native and osxcross configures, so CMake uses our BDB 6.2 header
instead of the SDK stub. Full-node only (lite has no BDB wallet.dat).
- Use the derived triple in require_wallet_rebuild_helper's fix hint.
Verified end-to-end by building both ObsidianDragon 2.0.1 and ObsidianDragonLite
1.1.0 .dmg/.app on an Intel Mac (x86_64; built single-arch via DRAGONX_MAC_ARCHS
since the vendored deps are x86_64-only).

daemon-startup hardening, seed-phrase backup, in-app FAQ, i18n + 8-language

Bump DRAGONX_LITE_VERSION 1.0.0 -> 1.1.0: since lite-1.0.0 the Lite variant
gained the whole 2.0.x shared UI/UX + diagnostics + i18n + perf work and this
session's chat delete/block — a minor bump (new features, no breaking change).
Make the FAQ variant-aware (walletFaq(fullNode)) so the Lite build reads
correctly: "What is ObsidianDragonLite?", encryption in the Wallet tab (not
Node & Security), migrate-to-seed hidden, node-specific answers reworded
neutrally ("the wallet syncs"), a new "Lite Wallet" subcategory (server model +
privacy tradeoff) standing in for the hidden Daemon group, and the redundant
single "Wallet" group tab dropped when there's no Daemon group to switch to.

The Linux and macOS release paths already strip the main binary (and the
Windows path even stripped the dragonx-wallet-rebuild helper), but the

Windows build, best-effort with a warning fallback.

- Auto-shield status: the node's z_autoshieldstatus disabled_reason was echoed
verbatim ("HD seed origin is not known-recoverable; back the seed up and pass
-autoshield=1") and drawn INSIDE the Wallet OPTIONS checkbox grid, wedging a
full-width line between the checkboxes. Move it to a full-width note BELOW the
grid, and replace the raw daemon text with friendly, actionable wording keyed
on the seed_recoverable flag (back up your seed to enable it); the raw daemon
reason is kept on hover. Adds App::daemonAutoShieldSeedRecoverable().
- FAQ: add a Chat & Contacts entry ("How do I hide, delete, or block a
conversation?") covering the hide / delete-revive / delete-&-block actions and
the local-only caveat — data + i18n only, no UI code change.

Immediate-mode render functions re-run every frame; these rebuilt O(N)
state each time even when nothing changed. From a 6-lens perf audit, each
finding verified on a hot-path basis:
- Console: ConsoleModel gains revision(); the full-model filter scan and the
glyph-by-glyph text-layout pass (BuildConsoleLayout) rebuild only when the
model / filter / wrap-width / zoom change — previously it re-shaped up to
10,000 lines every frame even when idle/scrolled. clear() force-invalidates
the memo mid-render (no OOB on the just-emptied visible set).
- Transactions: the summary-card totals memoize behind the tab's existing
FNV-1a fingerprint (also folds away a now-duplicate O(N) display-key pass).
- Send / Receive recent lists: early-exit the prefix scan (state.transactions
is kept newest-first) instead of filtering the whole tx history every frame.
- network_refresh_service: O(new x total) txid find-and-replace -> hash map.
- Sidebar unconfirmed-tx badge cached on last_tx_update + tx count; the
daemon-memory probe (/proc scan on Linux, popen on macOS) throttled to ~1.5s.

Adds a per-conversation "delete" with two modes, and removes the per-frame
rescans of the chat history that shared these files.
Delete conversation (header trash icon → confirm dialog):
- Delete (revive-on-new-message): clears local history and tombstones the
messages (new chat_deleted table, keyed dedup hashes) so the every-few-
seconds memo re-scan can't re-import them; a genuinely NEW message (new
txid) revives the thread.
- Delete & block: removes history WITHOUT a tombstone and records the cid as
blocked (settings); ChatService::ingest drops that conversation's messages
— old and future — until unblocked from the "Blocked" manager, which then
re-imports the conversation from chain.
- Local-only (messages remain on-chain; the peer keeps their copy).
deleteConversation() deletes the DB rows FIRST and only then mutates the
store, so a failed write can't leave the two diverged.
Unit-tested (revive / tombstone-survives-reload / block / unblock) and
adversarially reviewed (store/DB divergence, half-open DB, revive-unread).
Performance (chat + badge hot paths, from the perf audit):
- ChatStore gains revision(); the Chat unread badge is now a single O(N)
no-alloc pass cached on it (was O(conversations x messages) copy+sort every
frame). The conversation list and open thread are memoized on revision()
(+ show-hidden and AddressBook::revision() for peer-name resolution).
- AddressBook gains revision() so an in-place contact rename invalidates the
chat memo (an edit keeps entries().size() constant).

The Chat/History nav buttons centered their icon+label in a region that
shrank when a badge (unread count / mining dot) was present, and the
"has badge" test read the LIVE count — so the text jumped sideways the
moment a count toggled (e.g. a new chat message arrived). Reserve badge
clearance by whether the page CAN show a badge (constant per item), center
in the full button width regardless, and cap the label with symmetric
clearance so a long label still can't run under the corner badge.

Bundles the session's UI work (the touched files carry several of these
changes together, so they are committed as one coherent UI batch):
- FAQ: new RenderFaqDialog + data-driven faq_content, opened from a
status-bar "?" (and the Windows title bar), styled like the Wallets
modal with search, Wallet/Daemon tabs, and smooth scroll.
- DPI/font-scale audit: multiply hand-drawn absolute geometry by
Layout::dpiScale() across ~30 files so nothing renders native-size at
HiDPI / font_scale 1.5 (verified with a full sweep at 1.5x).
- Mining: chart now fills the horizontal space; thread stepper +/- buttons
match the input-box height; move the stratum-host toggle into
Node & Security (v1.3.0+).
- Settings: fix the auto-shield status text overlapping the grid.
- Sidebar: drop the peer-count badge on the Network button.
- i18n: wrap 193 hardcoded literals with TR() (keys/translations added in
the preceding i18n commit), so the security/PIN/lock flow, seed-backup
wizard, and witness-rebuild dialog localize.

Adds the i18n source for 193 previously-hardcoded UI strings (the
security / PIN / lock flow, first-run seed-backup wizard, witness-rebuild
shutdown dialog, and balance / mining / explorer labels) so they can be
localized. The TR() call-site wrapping rides in the accompanying UI commit.
- 193 keys added to loadBuiltinEnglish() (the English source of truth),
including one pre-existing missing key (copied_to_clipboard).
- Additive res/lang/{de,es,fr,ja,ko,pt,ru,zh}.json (+193 each); every
translation's printf format-signature was validated against English
(0 mismatches) so the runtime validator accepts them.
- Rebuilt res/fonts/NotoSansCJK-Subset.ttf to cover ~30 new Han/Hangul
glyphs introduced by the zh/ja/ko translations (tofu-free).

The node kept falling behind the network near the tip because sync
DETECTION was starved: getblockchaininfo was queued behind the
O(mapWallet) wallet RPCs (z_gettotalbalance / z_listunspent), so
longestchain went stale, the wallet decided it was "synced", and it
resumed hammering cs_main — a feedback loop.
- Issue getblockchaininfo FIRST each cycle and skip the balance/address/
tx refresh entirely while behind, so sync state (and kSyncProfile)
updates before any heavy wallet scan runs.
- Gate the two chat note scans (refreshChatNoteBudgetNode /
fastScanChatMemos) on effectivelySyncing() and the active page, so chat
memo scanning no longer competes with block connection during sync.
- Windows debug.log tailer: reset the read offset when dragonxd truncates
the log on startup (it was stranding at Block:0 with no witness/rescan
progress).
- Tests cover the getblockchaininfo-first ordering and behind-skip.

The shutdown guard fired its "Node is rebuilding its witness cache" prompt almost always on an
active wallet: the daemon does a per-tx VerifyAndSetInitialWitness as each newly received wallet
tx lands during normal sync, and those markers (sparse — minutes apart — with no matching
"rebuilt N note witness cache(s) … in Xms") kept the heuristic latched "active".
- daemonWitnessRebuildActive() now requires the last progress marker to be part of the CURRENT
log activity (within ~15s of the newest log line, via a same-log timestamp delta), so routine
minutes-old per-tx witness sets no longer count as an ongoing rebuild.
- shouldConfirmDaemonStop() suppresses the prompt entirely on v1.3.0+ daemons (version >= 1030000):
they checkpoint witness-rescan progress, so stopping mid-rebuild resumes on the next start rather
than redoing it — the warning's "restarts it (several minutes)" premise no longer holds.

The daemon-output parser treats autonomous background witness rebuilds as a rescan (they set
state_.sync.rescanning via the foundWitness branch), so one completing fired "Blockchain rescan
complete" even though the user never started a rescan — most visibly after a minimize, where a
whole rebuild's start+finish arrives in one batch.
Add user_initiated_rescan_ (atomic — some triggers run on worker threads), set it at the wallet's
real rescan triggers (the Rescan button, a -rescan/salvage/zap/reindex restart, key import, seed
migration), and gate the three "rescan complete" toasts on it, clearing it when shown. The
rescan/witness progress state machine is untouched — only the toast is gated — so background
rebuilds no longer announce a completed rescan while genuine user rescans still do (and can't
double-toast).

Previously the main loop just did SDL_Delay+continue when minimized, skipping app.update() —
so the wallet stopped draining RPC results, ticking the refresh scheduler, and reconnecting
until it was restored (and a large daemon-output backlog piled up, which is what produced the
spurious "rescan complete" toast on restore).
Now app.update() runs while minimized (it only reads GetIO/GetTime/IsAnyItemActive, all valid
outside a NewFrame) with a real-clock DeltaTime, skipping only the ImGui frame + GPU present,
throttled to ~5 Hz so CPU stays near-idle. Also clamp io.DeltaTime at the top of App::update()
so a long minimize (or machine sleep) can't report a huge delta and fire every refresh/animation
timer at once on the next update. No backlog now builds, so skipDaemonOutputBacklog becomes a
harmless no-op.

While minimized the main loop skips the frame body (SDL_Delay+continue), so App::update() —
which drains the daemon output via outputSince(daemon_output_offset_) — never runs and the
offset isn't advanced. On restore the whole accumulated backlog is parsed in one batch: a
background witness rebuild's progress lines (parsed as a rescan → state_.sync.rescanning=true)
AND its "rebuilt … in Xms" completion (parsed as finished) arrive together and fire
"Blockchain rescan complete" for a scan the user never initiated.
On WINDOW_RESTORED, discard the daemon-output backlog (advance the offset to the current end,
via App::skipDaemonOutputBacklog) before the resumed update parses it — so only new output is
parsed. Genuine user-initiated rescans still surface completion via the getrescaninfo monitor.

It added clutter to the loading screen (the yellow title + two lines of explanatory text).
The live daemon-output panel below it is the real progress signal. connect_stall_since_ stays
maintained in app_network.cpp for connection bookkeeping; it just no longer drives any on-screen
text (loading_stall_* i18n strings + util::connectHasStalled are now unused).

Add an opt-in "Host a mining pool (stratum)" toggle so a v1.3.0+ node can run its native
RandomX stratum server for other miners to point at. Settings toggle + optional allow-IP/CIDR;
passes -stratum (+ -stratumallowip) to the daemon launch args, mirroring the -maxconnections
plumbing (EmbeddedDaemon::setStratumHosting <- DaemonController::syncSettings <- Settings).
Backwards compatible / safe by default:
- UI gated on daemon_version >= 1030000, so it's never offered where it would do nothing.
- The launch flag is harmless on older daemons (they ignore unknown args), and the toggle can
only be enabled while connected to a v1.3.0+ node anyway.
- Blank allow-IP => the daemon serves loopback only (its safe default); entering a subnet opens
it to that LAN, with an explicit exposure warning in the UI.
- Takes effect on the next daemon start/restart.

Rec3 — v1.3.0+ opens a wallet that lost its hdchain in DEGRADED mode (existing funds spendable,
but no new HD-key derivation) instead of aborting. Add a daemon-log classifier
(walletOpenedDegraded) + detectWalletDegraded(), warned once per session. Pre-1.3.0 daemons
never emit that line, so it's a no-op there.
O1 — probe z_autoshieldstatus once per connection (now decoupled from our own toggle/balance) and,
in Settings, show whether the node handles auto-shield itself (+ its destination, or the daemon's
disabled_reason). The checkbox now governs only the wallet's fallback shielder, which defers to the
node. Nothing renders on pre-1.3.0 daemons (no such RPC), so behaviour is unchanged.
