DanSandClaude Opus 5.5 b50d5ac31f perf(startup): build the font atlas once at the final ui.toml sizes
main() built the font atlas before App::init() loaded ui.toml, so the
first build used the hard-coded fallback sizes (H1 24 px, Body2 12 px).
App::init() then rebuilt for a saved font scale above 1.0, still before
the schema load and so still at the fallback sizes. Only the color-emoji
rebuild requested for the first frame reached the ui.toml sizes, so
color-emoji users built the atlas twice at font scale 1.0 and three
times at 1.5.

Users with chat_emoji_color=false never got that last rebuild. They
built the atlas once or twice and ran the whole session at the fallback
sizes, e.g. Body2 at 12 px instead of 15 and H1 at 24 px instead of 20.

Now:
- App::loadBaseUiSchema(), the ui.toml load moved out of App::init()
  unchanged, runs in main() before both InitImGui paths (DX11 and GL),
  together with the saved font scale and emoji style from the early
  settings read. It is idempotent, so the call left in App::init() is a
  no-op;
- the two rebuild triggers in App::init() are gone;
- Typography records what the atlas was built from (the 15 schema sizes,
  the schema's font scale, the effective emoji style and the schema
  generation), and preFrame() rebuilds once when they differ. While the
  schema generation and the emoji style are unchanged this costs two
  compares per frame.

Measured on the Lite build (color and mono emoji, font scale 1.0 and
1.5, English and Japanese): every run builds the atlas exactly once, at
the ui.toml sizes times the scale (H1 20 px and Body2 15 px at 1.0,
30 px and 22 px at 1.5), and ui.toml is loaded before the window and GL
context are created. The packaged Lite zip and AppImage log one atlas
build instead of two. Color-emoji screenshot sweeps match the previous
build within noise.

Visible changes:
- users with chat_emoji_color=false had been rendering the whole UI at
  the fallback font sizes; they now get the designed ui.toml sizes, so
  every mono-emoji screen differs from before and matches the
  color-emoji layout;
- a user skin whose [fonts] differ from ui.toml now rebuilds the atlas
  once when it is activated or left; on a runtime switch the atlas used
  to keep the old sizes until a restart. With a test skin that sets
  Body2 to 18 px, startup builds twice and ends at 18 px; switching to a
  bundled skin rebuilds once, switching among the 9 bundled skins
  rebuilds nothing (they carry an identical copy of [fonts]), and
  switching back rebuilds once;
- editing ui.toml while running still gives exactly one rebuild.

Not verifiable here: the Windows DX11 path with the schema loaded before
its first FreeType build, macOS, and the interactive font-scale slider,
Alt+scroll and emoji toggle, which were checked by reading the code.

DanSandClaude Opus 5.5 3f13d79ccb perf(ui): memoize the node-status banner ellipsis
While the node-status banner shows, its detail line was fitted every
frame by popping one character at a time and re-measuring the whole
"·  " + detail + "…" string: O(L^2) per frame in the detail length L,
which adds up on the ~1.5 KB Windows crash report. The pop also left a
dangling UTF-8 lead byte before the "…", so a cut in non-ASCII text drew
replacement characters in place of the ellipsis.

- util::textfit::ellipsizeTail builds the same string in O(L + m log m),
  m being the length of the line the cut lands in: ImGui measures
  multi-line text as its widest line, so the old loop could only stop
  inside the first line that overflows on its own. Byte-identical for
  ASCII; the cut now lands on a code-point boundary.
- EllipsisFitCache keeps the result until the detail, budget, font size,
  font (by FontId) or rasterizer density changes, so an unchanged frame
  costs one string compare.
- When ImGui would draw a line wider than the per-line split predicts
  (a malformed byte joined with the following newline, as in CP-1252
  output from the Windows daemon), the old whole-string loop is used for
  that text.

DanSandClaude Opus 5.5 971f2abae5 perf(startup): prepare first-run node files in the background
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.

DanSandClaude Opus 5.5 47180ff840 perf(startup): stat dragonxd instead of reading it for the update offer
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.

DanSandClaude Opus 5.5 55975901a2 perf(lite): move wallet ops and server switches off the UI thread
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.

DanSandClaude Opus 5.5 296c04386c perf(mining): sample daemon memory off the UI thread
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).

DanSandClaude Opus 5.5 2618744e59 fix(rescan): probe the node's block range off the UI thread
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.

DanSandClaude Opus 5.5 ad0f60a747 perf(market): fetch price and market data on a dedicated HTTP lane
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.

DanSandClaude Opus 5.5 93b6871511 perf(history): write the history snapshot on change, off the UI thread
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.

DanSandClaude Opus 5.5 6c02e67c6d perf(mining): one save, at most one restart per thread-count gesture
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.

DanSandClaude Opus 5.5 7649b1f8a3 perf(settings): write settings.json and wallets.json off the UI thread
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.

DanSandClaude Opus 5.5 cee8b9d7f6 feat(merge): run per-address consolidation as a paced background job
"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.

DanSandClaude Opus 5.5 b29a09eaa0 perf(chat): sends re-read by origin, chat scans under the scan budget
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.

DanSandClaude Opus 5.5 f86cc4d6b7 perf(net): hold wallet scans at connect, in the background and on tab entry
- 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.

DanSandClaude Opus 5.5 323143e111 perf(net): one scan budget for all wallet scans, gated on what changed
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.

DanSandClaude Opus 5.5 879de37d18 perf(history): scan shielded history in bounded passes, not every block
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%.

DanSandClaude Opus 5.5 8b9a498eee perf(net): one balance scan per poll, filtered opstatus, a guarded merge scope
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.

DanSandClaude Opus 5.5 2cf183ddd9 perf(mining): run the mine-when-idle check at 1 Hz, probe the GPU sparingly
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.

DanSandClaude Opus 5.5 2d29a04981 perf(ui): stop forcing full wallet re-scans on restore and peers refresh
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.

DanSandClaude Opus 5.5 43fc0090d4 fix(wallet): retire tracked sends that only paid the wallet itself
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.

DanSandClaude Opus 5.5 1cb03332e7 fix(net): stop re-running the connect sequence while the wallet is locked
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.

DanSandClaude Opus 5.5 575abd4bcc perf(ui): render frames on demand instead of continuously
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).

DanSandClaude Opus 5.5 fffab228d1 fix(ui): apply the saved appearance settings at startup
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.

DanSandClaude Opus 5.5 402a3053dc fix(app): advance logic timers by wall-clock time
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.

DanSandClaude Opus 5.5 a3361020d1 feat(daemon): recognise our detached node, tail POSIX debug.log, more RPC threads
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.

DanSandClaude Opus 5.5 e20b70d73f fix(daemon): never restart, delete or swap under a node that hasn't exited
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.

DanSandClaude Opus 5.5 1215ded1a0 feat(ui): say "Node busy" instead of "Launching dragonxd"; honest quit copy
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
  removed; CJK subset rebuilt for the new glyphs.
- Tests: chooseDaemonStatus, NodeBusy banner priority, and every new key
  present in all 8 JSONs with matching printf conversions.

DanSandClaude Opus 5.5 0f25c67600 feat(rpc): stop flooding a busy node's RPC queue; fix the reconnect storm
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.

DanSandClaude Opus 5.5 6b14098bb2 fix(daemon): make the "keep the node running?" prompt actually appear
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.

DanSandClaude Opus 5.5 5993488176 feat(daemon): deliver stop reliably and never kill the node unasked
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.

DanSandClaude Opus 5.5 a091bbc52f fix(daemon): never kill a dragonxd the wallet didn't launch
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.

DanSandClaude Opus 5.5 2c04b88e19 fix(daemon): let POSIX stop() see the daemon exit instead of always SIGKILLing
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.

DanSandClaude Opus 4.8 fae8b20fb7 fix: FAQ CJK glyphs, outgoing-tx history, lite encryption, migrate & sync safety
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.

DanSandClaude Opus 4.8 d9fa00bb38 perf: memoize per-frame render hot paths (console, transactions, recent lists)
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.

  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.

DanSandClaude Opus 4.8 56d93b6128 fix(shutdown): don't warn "node is rebuilding" for routine witness activity / on v1.3.0
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.

DanSandClaude Opus 4.8 398fb274fa fix(ui): only toast "Blockchain rescan complete" for user-initiated rescans
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).

DanSandClaude Opus 4.8 0343d48c13 feat(ui): keep the wallet syncing while minimized
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.

DanSandClaude Opus 4.8 a3892c0fd3 fix(ui): stop spurious "Blockchain rescan complete" toast after restoring from minimize
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.

DanSandClaude Opus 4.8 f7df315695 fix(ui): remove the "Taking longer than expected" startup stall notice
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).

DanSandClaude Opus 4.8 7e8b99a82b feat(shutdown): confirm before stopping the daemon mid witness-cache rebuild
Stopping dragonxd while it's rebuilding the Sapling witness cache discards the
in-progress work — BuildWitnessCache aborts on shutdown without persisting — so
the next launch redoes a multi-minute rebuild (the "Activating best chain…" hang).
This bites especially with stop_external_daemon enabled, where wallet exit sends
the node a stop.

beginShutdown() now defers when it would StopDaemon while a rebuild is active and
shows a confirm modal: "Keep node running & quit" (DisconnectOnly — leaves it up
to finish), "Stop anyway & quit", or "Cancel". Rebuild detection reads the
debug.log tail markers (Cleared witness data / Setting Initial Sapling Witness /
Reading blocks for witness rebuild, vs. the "rebuilt … in …ms" / abort lines).
The gate lives entirely in beginShutdown()/render() — no SDL event-loop changes.

DanSandClaude Opus 4.8 29274c2f48 fix(ui): trim verbose startup notice; show daemon output on shutdown for external daemons
- Loading "taking longer than expected" notice: shorten the body + hint so the
  startup screen reads less wordy (same info, ~half the text).
- Shutdown screen: when the wallet attached to an EXTERNAL daemon (no captured
  stdout — debug_log_path_ is only set when we spawn it), the "dragonxd output"
  panel was always empty, leaving just a spinner. Fall back to tailing the
  daemon's debug.log so the user can watch the node flush the block index and
  exit. Adds App::tailDaemonDebugLog() (best-effort, reads only the file tail).

DanSandClaude Opus 4.8 870793433b fix(sync): stop large-wallet balance polling from starving block connection
On a fully-shielded (ac_private=1) chain, z_gettotalbalance is O(mapWallet) and
holds the daemon's cs_main for its whole duration — ~20s on a ~5k-tx wallet. The
Overview refresh polled it every ~2s (twice: minconf 0 and 1), so cs_main was
held almost continuously, starving the single block-connection thread: the node
connected blocks only in the gaps between polls and could fall further behind
the tip than it caught up (observed live: gap growing 58→100 blocks while the
GUI was open, one core pegged on GetFilteredNotes, 22 idle, ~17 B/s download).

Two hardening changes on top of the existing "skip balance while syncing" guard:

- Hysteresis: keep the low-impact sync profile (and balance suppression) for a
  short settle window after catching up, so a large-wallet scan can't
  immediately re-starve connection and bounce the node back into syncing. Armed
  only on the syncing→caught-up edge, so a wallet synced from the start is never
  throttled at connect (effectivelySyncing()).

- Adaptive balance cadence: time each z_gettotalbalance scan and require the
  next poll to wait at least (cost / 10%), so balance scanning never occupies
  more than ~10% of wall-clock. Cheap wallets are unaffected (the tab's Core
  timer stays the cadence); a ~20s scan backs off to ~200s. Wallet mutations
  (send/shield) force the next poll through so the user's own action updates the
  balance immediately (balanceRefreshDue()).

getblockchaininfo keeps its normal cadence throughout, so sync progress stays
live. Build + test_phase4 green.

DanSandClaude Opus 4.8 5daf2d83b6 feat(ui): large-wallet nudge as a one-time toast + clickable alert
Extend the wallet-bloat warning beyond the Settings banner: when wallet.dat
first crosses 500 MB (full-node, synced), fire a one-time warning toast plus a
clickable "Consolidate notes…" entry in the bell/alerts panel that opens Merge
to Address. The persisted large_wallet_warned flag keeps it once-only and
re-arms if the file later shrinks back under the threshold.

- AlertRecord gains an optional onClick + actionHint; Notifications::action()
  pushes a toast and a clickable history entry. renderAlertHistoryPanel() now
  renders the accent action link (under the message) and measures true content
  height so wrapped messages + the link aren't clipped.
- App::maybeWarnLargeWallet() (mirrors maybeRemindSeedBackup) runs once per
  launch from update(); reuses the existing wallet_size_warn/consolidate strings.

DanSandClaude Opus 4.8 558cfcbe56 fix(ui): restore ObsidianDragon logo in header and About tab
ensureLogoTexture() rasterized the embedded DragonX SVG into logo_tex_ and
returned early (added in 1752500 "themed DragonX logo"), so the app/product
branding — the top-left header (app.cpp AddImage) and the About tab
(getLogoTexture) — showed the DragonX coin mark instead of the ObsidianDragon
logo. Drop that step so logo_tex_ resolves via the intended path: active-skin
override → ui.toml header-icon → bundled ObsidianDragon dark/light PNG (disk,
then embedded RESOURCE_LOGO). The DragonX SVG stays for coin_logo_tex_ (balance
card) and drgx_emoji_tex_ (chat emoji), which are the currency mark and correct.

DanSandClaude Opus 4.8 d0bd55b9c1 feat(ui): settings polish — button retune, daemon card, RPC 2-row, chat preview
Settings tabs brought closer to the approved mockup:
- ActionButton/renderCardButton retune (settings-scoped): 7px radius, 9px
  padX, Primary → accent-outline chip, Secondary/card buttons more defined.
- Daemon-binary card: compact status right-aligned on the DAEMON BINARY
  heading (Up to date / Version differs / Not installed), filled/rounded
  status box, neutral danger divider (was alarming red), roomier spacing.
- RPC Connection: two-row column-aligned layout (Host | Port, then
  Username | Password) so the password no longer clips off the card edge.
- Chat settings tab: live conversation preview below the Appearance /
  Messaging cards; "Focus input on open" checkbox reflowed onto the console
  color-toggle row.
- Debug Options: "Current theme only" toggle restricts either screenshot
  sweep to the active theme instead of cycling every skin.
- Tabs fill the full content width (content-max-width cap disabled) and the
  sidebar nav panel centers within the true visible area.
- i18n: new keys for the above (untranslated keys fall back to English).

DanSandClaude Opus 4.8 8778398d31 feat(ui): layout polish — fill dead space, pair/box/collapse, warning weight, dialog glass
Implements the layout-improvement suggestions from the layout audit (visual arrangement
only; no functionality added or removed):

- Send/Receive: the recent-activity list now grows to fill the space below the fixed
  compose/receive card (more history visible), with a centered empty-state when there is
  none — instead of leaving dead canvas.
- Shield/Merge: pair the Fee and UTXO-Limit fields on one row to tighten vertical rhythm.
- Market: extend + frame the portfolio group-list as one contained panel (with a bottom
  edge) and center its empty-state, closing the previously un-anchored gap.
- Overlay dialogs: raise the card glass fill/border alpha (35/50 -> 60/90 of 255) so the
  dialog card reads as a distinct surface over busy backdrops (global, all overlays).
- Wallets: size the list height to the actual wallet count instead of always reserving 7
  rows, removing the large gap before the scan/create prompts (still scrolls when many).
- Contacts: width-aware address truncation shows more of the address on wide rows.
- Transfer Funds: give the "sends the full balance" warning a warning icon + color so the
  stakes stand out from the neutral result-preview lines.
- First-run wizard: collapse a completed Step 1 (Appearance) to the compact pill like
  Step 2, so a finished step is no longer taller than the active one.
- Explorer: distribute the Chain card's two stats to match the density of the sibling
  metrics grid.
- Validate Address: a "Results will appear here" caption fills the pre-interaction blank.
- Change Passphrase: add the warning banner its sibling security dialogs have.
- Migration ShowSeed: box the 24-word mnemonic grid (a GlassSectionScope behind the
  existing RenderSeedWordGrid) so the critical secret reads as a distinct artifact —
  purely visual, no seed/logic/state change.

Verified at 1280 across full-node + Lite + Windows (ctest green) and an adversarial diff
review (clean). New i18n key backfilled into all 8 languages.

DanSandClaude Opus 4.8 9205addf55 feat(ui): width-responsiveness — content max-width cap + per-surface form/input clamps
Wide/ultrawide (1440-3440px) responsiveness was unhealthy: no page/content-level
max-width cap existed, and every card/form/table derived width from raw
GetContentRegionAvail().x with floor-only clamps, so surfaces stretched edge-to-edge
(2000-3000px inputs, ballooning cards, giant grid cells, 2000px+ dead row-voids).

Root cause: adopt the (previously dead-code) clamp helpers.
- New Layout::kContentMaxWidth() (~1600dp, tunable via ui.toml [layout]
  content-max-width; <=0 disables). Cap ##ContentArea to it and center the column in
  wider windows — every tab derives from this child, so one change tames the app at
  wide widths. No-op below the cap (fills as before), so 1080p/1440p are unaffected.

Per-surface upper-clamps (std::min(cap*dp, expr), floors preserved) where a single
element is still too wide even within the capped column:
- Settings: Theme/Layout/Language combos, the font-scale slider (~3000px -> 360dp),
  the effect sliders, Explorer URL and RPC credential fields.
- Send / Receive: cap the compose / receive cards to a readable form width and center
  them (Indent(pad+offset) so the auto-layout fields align with the hand-drawn card);
  the recent-tx lists below keep the full column width.
- Chat message bubbles + composer, mining pool URL/payout inputs + stats left/right
  split, contacts search, and the lite-network add-server row / server cards / status
  panel (capped + centered).
- Wizard: vertically center the cards when they fit (was top-anchored, leaving a void
  on tall monitors), compensating the content-height measurement so it can't oscillate.

The 1600 cap also subsumes the fixed-4-column balance grids (~400px cards) and the
right-anchored row dead-gaps (voids shrink from ~2700px to ~800px), so those are left
to the cap rather than blind column/row redesigns.

Verified at 1024/1280 (and via a temporary 900dp cap to exercise the cap+center path,
since the test display clamps to 1280) across full-node + Lite + Windows (ctest green)
and an adversarial diff review (clean). The true wide/ultrawide look and the 1600dp cap
value still want eyes on a real wide monitor.

DanSandClaude Opus 4.8 e24ca015d1 feat(ui): implement UI/UX audit — i18n, HiDPI, theme, destructive-action & overflow fixes
Implements all 26 confirmed UI/UX audit findings plus the 4 dashboard/timeline
tile labels. Verified across full-node + Lite + Windows builds (ctest green) and
an adversarial diff review (one market-tab delete regression caught + fixed).

i18n coverage:
- Balance hero/quick-actions/toasts + dashboard & timeline tiles (Total Balance,
  Shielded, Transparent, Quick Send, Quick Receive, Click to open, Market)
- Send: Review Send / Cancel / Paste / view-only tooltip / memo byte counter
- Settings: Lite lifecycle errors, plaintext-RPC security warning, 8 toasts
- Mining pool-payout tooltip
- Resolve daemon_update_title double-assignment collision (new daemon_update_prompt_title)
- 23 new keys translated into all 8 locales; CJK subset font rebuilt

HiDPI: DPI-scale the Send amount bar, mining thread-tile clamp bounds, receive
loading skeleton, and sidebar notification-badge insets.

Light theme: theme-aware material::SurfaceOverlay() for balance bar tracks and
row-hover highlights; contacts active-pill foreground uses OnPrimary().

Destructive actions: arm/confirm for portfolio-group delete, saved pool/worker
remove, and avatar-image delete.

Interaction/overflow: route balance star/eye buttons and the console fold-toggle
through popup-safe guards; clip peer addr/subver; truncate the balance custom
label; measure Settings tool-button widths; mining stepper disabled-state
feedback; +/- stepper buttons restyled to match the thread tiles.
