The Validate address dialog chose its RPC from the first character of
the input, then asked the transparent-only validateaddress for every
case. That RPC is Base58-only, so a valid Sapling (z) address came back
isvalid=false and was reported invalid.
- The input is now classified with the checksum-verified recognizers,
and a shielded address is sent to z_validateaddress while a
transparent (mining) address keeps validateaddress.
- Anything that is not an address - a typo, garbage, or a pasted
viewing/spending key - is judged invalid on the spot and never sent to
the node, so a key pasted into the field is not leaked to an RPC.
- On Lite there is no node to ask, so the dialog shows the checksum
verdict alone and hides the "owned by this wallet" row.
Tests: validateRpcMethod maps shielded to z_validateaddress, transparent
to validateaddress, and a key or empty string to no RPC.

The auto-lock idle clock was reset whenever any ImGui item was active,
so a text field left focused (a half-filled send form, say) counted as
continuous activity and kept the wallet unlocked indefinitely, well past
the configured idle timeout.
- The idle clock is now fed by real input events (key, text, mouse,
touch, pen, gamepad button) as they are ingested on the main thread,
plus a still-held mouse button so a drag or scrollbar grab that emits
no new event still counts. A focused but untouched widget no longer
does.
- A new header-only IdleTracker owns the clock and never moves backwards,
so an event stamped before the previous one cannot shorten the idle
time.
Behaviour change: a form left focused and idle past the timeout now
auto-locks. The form's buffers are app state and survive the lock and
unlock, so nothing typed is lost.
Tests: a new IdleTracker case covers idle time growing with no events
(enough to trip a 900s lock), activity resetting it, the clock never
moving backwards, and a query before the last activity reading zero
rather than a negative value.

The bootstrap preflight's protected names could be bypassed by names
that resolve onto them, and its cancel and quit paths had two timing
gaps.
- Entry names are judged as the file system resolves them: '\' is a
separator, "." components are dropped and each component loses its
trailing dots and spaces, as Win32 does ("./wallet.dat" and
"DRAGONX.conf." name protected files). The whole archive is refused
for an absolute or drive-rooted name, a ".." component, any ':'
(drive letter or NTFS alternate data stream, "DRAGONX.conf::$DATA"),
an 8.3 short name ("DRAGON~1.CON"), a component of only dots or
spaces (other than "."), and any byte >= 0x80 or ASCII control
character: macOS folds or ignores some Unicode (U+017F, U+212A,
U+200C) onto a protected name, and the published bootstrap archive
uses plain ASCII names. A refused name is echoed
with \xNN escapes. A member is written at the path it was checked
under, and the protected-name check runs on the resolved name.
- The user's Cancel (Settings dialog and first-run wizard) goes through
requestCancel(). It is refused once the old chain data starts being
replaced, and the start of that window re-checks a cancel under the
same lock, so a click lands before the old chain is touched or not at
all.
- Quit cancels the wizard's and the Settings bootstrap when the
shutdown starts; the HEAD and checksum requests now end at once on
cancel, and a cancelled HEAD keeps the partial download. A run
cancelled before the window leaves the old chain as it was. A run
inside it stops extracting and removes its partial chain while the
shutdown screen shows "Cleaning up...", so it ends with no chain data
(wallet.dat untouched; Retry reuses the zip, or the node resyncs).
That wait is bounded: at most 2 minutes from the start of the
shutdown, then 3 s in shutdown(), after which a worker still running
is left to the process exit. Only a cleanup that overruns that cap
can leave a partial chain, which dragonxd then answers with its
reindex offer.
Tests: refusal of the Windows-resolved, non-ASCII and control-character
names with the escaped echo; the protected-name list incl. the resolved
forms and a planted -wallet file, conf and database/ that stay
byte-identical; the user-cancel window; the bounded quit wait and
safeToAbandon(); a cancel ends a HEAD request that never answers.

The "Use Tor" checkbox was saved but never read: no build routed any
traffic (node, RPC, price/update/bootstrap/pool HTTP or Lite gRPC)
through Tor, so users who ticked it believed they were anonymous.
- The checkbox is disabled and always shown unticked, on the Settings
page and in the legacy Settings window. Its tooltip says it is not
available and gives the alternatives: for the node, proxy=127.0.0.1:9050
in DRAGONX.conf with Tor running; otherwise a system-wide VPN/Tor (Lite
builds get the short version). The "Use Tor" label is kept.
- Behaviour change: a stored use_tor=true is cleared once at startup
(Settings::consumeLegacyUseTor + a synchronous save before the async
writer and any Settings page state), with a 20 s warning in the user's
language. The cleared key is the "already told" flag, so the notice
never repeats. No settings format change.
- 3 new strings (tt_tor_unavailable, tt_tor_unavailable_lite,
tor_never_applied_notice) in all 8 languages; the tooltip wraps at
tor-tooltip-wrap-width from ui.toml.

A rescan or key import holds the node's cs_main for the whole wallet
scan. On the shared clients it hit the 30 s curl timeout, reported a
failure that wasn't one, abandoned a daemon RPC slot and flipped the app
into "node busy".
- One long wallet RPC at a time (rescan, importprivkey, importaddress,
importwallet, z_importkey, z_importviewingkey, z_importwallet) runs on
its own ungated client with no client timeout (rpc/long_call_lane.h).
It can be aborted from any thread, and an abort is never lost, even
one that lands before the client opens.
- The GUI rescan, key import and sweep use it. The sweep's fund-moving
body is unchanged; only the client it calls differs. runtimeRescan()
returns bool, and a refused post-bootstrap reconcile stays armed.
- The console routes rescan and the import commands through the lane;
its input stays usable meanwhile, and a refusal is printed like any
other result. RPCClient gains callRaw(.., timeoutSec).
- Restart, wallet switch, delete-chain, bootstrap (now also from
Settings) and the other node-stopping flows are refused while it runs,
with a message saying a key import or rescan is still running; quit
asks for confirmation. The lane is aborted at quit.
- A second import or rescan is refused before the key is copied anywhere.
An import cut off after the request reached the node (a lost reply,
or a proxy's 502/504 while the node still imports) says the key may
already be in the wallet and to run Settings -> Rescan. Only the
node's own HTTP-layer refusals (401, 503, work queue full, unhandled
request) say that the key was not imported. A pure
classifyLongCallCutOff() makes that choice.
- New strings in all 8 languages; console results stay English.
Tests: the long-method list and the console's routing; one lane at a
time; an abort lands whether it comes before the client opens or during
the call; a call with no client timeout outlasts a 3 s scan, where a 1 s
gated client times out and marks the node busy; classifyLongCallCutOff()
for every failure kind with and without a sent request, and from raw
HTTP replies (502, 504, a plain 500 -> cut off; 401, 503, queue full,
unhandled -> refused).

The bootstrap removed blocks/, chainstate/ and notarizations/ first and
only then opened the archive. An unsafe entry, a full disk or a corrupt
member therefore left no chain, or a half-written one for dragonxd to
start on.
- Preflight before anything is deleted: every archive entry must be
safe (no absolute path, no "..") and readable, and the disk must hold
the extracted size plus max(256 MiB, 5%), counting what removing the
old chain frees (a symlinked chain dir counts 0). Free space counts as
unknown only when the probe errors, the capacity is 0 or the
available size is -1; a known disk with 0 bytes free is a refusal.
The old chain is kept on every preflight failure.
- Protected members are skipped, compared case-insensitively: any path
component starting with "wallet", any "database" component, a .cookie
or *.conf file, and top-level *.dat files other than fee_estimates,
peers and banlist. The number of non-critical member failures is
logged.
- The removal of the old chain is verified (a locked file fails the run
instead of mixing old and new chain files). If the extraction fails or
is aborted, the partial chain is removed again before the failure is
published; isDone() turns true only after the worker's last
filesystem change.
- Cancel is disabled while the old chain data is being replaced, and
quit aborts a running bootstrap.
- A complete zip from an earlier attempt is reused on Retry; its
checksum is re-verified. A download that cannot fit fails early, and a
disk-full write error says so.
Tests: the space rule (boundaries, unknown vs. full disk, saturation);
planArchive sizes, zip-slip, garbage and truncated zips; the
protected-name list; reclaimableBytes with symlinks; each preflight
refusal keeps the old chain and wallet.dat byte-identical; a corrupt
critical member removes the partial chain before the failure is
published.

A passphrase change left the PIN vault sealing the old passphrase. The
next PIN unlock opened the vault, walletpassphrase answered RPC -14, and
the generic catch ran the lockout curve on a correct PIN, while Settings
kept showing the PIN as active.
- Passphrase change: when the active wallet's vault exists at completion
(same vault path as at dispatch, passphrase actually changed), the
vault is marked out of date for the session and kept on disk: PIN entry
is no longer offered, a warning toast says so, and Settings shows
"PIN out of date" with a tooltip on how to fix it. The Change
Passphrase dialog notes beforehand that a PIN will go out of date.
- PIN unlock: RPC -14 after the vault opened is treated as "PIN out of
date": passphrase entry, a message, no attempt counted, no lockout, and
the vault is not deleted (-14 is only the daemon's answer; the vault may
hold the only copy of a passphrase that opens an older backup). After a
restart Settings shows the PIN as active until the first PIN attempt.
- A malformed vault (zero-filled by a removeVault() whose unlink failed,
truncated, unknown version) is treated as missing: passphrase entry,
"PIN file unreadable", no penalty. New SecureVault::isWellFormed().
- Race guards: Set/Change/Remove PIN are disabled while a passphrase
change runs, and Change Passphrase while a PIN operation runs.
- Setting or removing the PIN, or switching wallets, clears the mark;
setting a PIN offers PIN entry again. Change PIN keeps the mark (the
vault still seals the same passphrase).
- Pure decisions in data/pin_vault_policy.h, unit-tested. New strings in
all 8 languages.
No vault, wallet or settings format change.

The full UI sweep (dev builds only) ran its demo surfaces against the
real profile. Its teardown deleted wallet-{cold,trading,mining,donations,
2023,payroll}.dat from the real datadir, it created zero-filled wallet
files and picker-demo/extra-wallets folders, its demo wallet-index upsert
re-minted the active wallet's scopeId (hiding "w:"-scoped contacts), the
Contacts tab could re-attach legacy-scoped contacts to such a throwaway
id in addressbook.json, and it persisted the demo active wallet file and
Mining pool worker.
- Preflight: a full sweep is refused (toast + log line) while a real
workflow is in flight: a pending seed_migration_* setting or open
migrate dialog, a wallet switch, an encryption/import workflow, an
encrypt/PIN/lock operation, the seed-backup dialog, or a bootstrap.
The DRAGONX_FULL_SWEEP hook then exits as for an empty catalog.
- Persistence latches: AddressBook (snapshot on the first sweepBegin,
save/load latched while a demo-contacts surface is shown), WalletIndex
and Settings (active wallet file, contacts view mode, pool URL/worker)
for the whole sweep. Settings::sweepEnd() is the last statement of
clearDemoWalletData and flushes once only if a save was suppressed; a
quit mid-sweep writes nothing to the profile (the 0700 sandbox, with
zero-filled demo files only, may stay in the temp dir).
- Scope ids: during a full sweep activeWalletScopeId() returns the
persisted id or "" and never mints one, so the Contacts tab cannot
move legacy-scoped contacts to a throwaway id. The only address-book
write a sweep can still cause is the one-time legacy re-attach to the
wallet's persisted id, which opening Contacts does anyway.
- Sandbox: demo wallet files and folders go to a fresh random 0700 dir
under the temp dir (exclusive create, a pre-existing path or symlink
is refused), removed at sweep end. The teardown that deleted those six
wallet files is gone.
- Cleanup: the migrate-to-seed state, wizard phase, demo chat
conversations and a fabricated demo chat identity are reset at sweep
end; the seed-backup surface always shows the demo phrase and a real
z_exportmnemonic result is dropped while the sweep runs.
- i18n: one new key (screenshot_sweep_refused) in i18n.cpp and the 8
language files.
Tests: the address book snapshots only on the first sweepBegin, keeps
addressbook.json byte-identical while latched and restores the real
book; the wallet index keeps wallets.json and the real scope id, also
with the background writer attached; Settings restores the latched
values and flushes once only when a save was suppressed; the sandbox
helper refuses a pre-existing path or symlink and removes only a
prefixed dir, never a symlink's target.
Release note: v2.0.x UI sweeps could delete wallet-{cold,trading,mining,
donations,2023,payroll}.dat from the data directory and re-scope
contacts; this cannot be undone automatically.

The Lite "Encrypt wallet" field and the Create/Restore passphrase had no
confirmation and no minimum length; only an empty passphrase was
refused. Encrypting locks the wallet at once, and a locked wallet cannot
reveal its seed, so a typo there could cost a user without a seed backup
their funds. The full-node encrypt dialog already requires 8 characters
and a confirmation.
This applies to new passphrases only. Opening and unlocking are
unchanged: an existing wallet with a shorter passphrase still opens and
unlocks.
- A pure liteEncryptPassphraseValid(pass, confirm): at least 8 bytes and
equal to the confirmation. It takes string_views, so the page's secret
buffers are never copied.
- liteLifecyclePassphraseAcceptable(op, pass, confirm) gates the Settings
create/open/restore request. Open is never checked, because its
passphrase field also unlocks an existing wallet. Create and Restore
are checked only when a passphrase was entered; an empty one still
creates an unencrypted wallet.
- Encrypt gets a Confirm field. The button stays disabled until the
passphrase is valid, and a hint says why (too short, with the count,
or not matching).
- Create/Restore show a Confirm row once a passphrase is typed, with the
same hint. Validate stays disabled while the passphrase is invalid, so
a click never wipes a typed seed over a passphrase typo. The request
builder re-checks the rule.
- The confirmation buffers are wiped with their passphrase: after a run
or an encrypt, and when the Confirm row is hidden.
- Once the wallet is closed, the Settings page wipes the Encrypt,
Confirm and Decrypt passphrase buffers whole every time, also when no
secret was revealed; before, closing the wallet wiped them only while
clearing a revealed backup or secret. They are zeroed in full because
an emptied field can still hold the old tail past its first NUL.
- New copy under Encrypt: "Anyone with the wallet file can try
passphrases offline. Back up your seed phrase first and use a long
passphrase."
- i18n: three new keys (lite_confirm_label, tt_lite_confirm_pass,
lite_encrypt_offline_warning) in i18n.cpp and the 8 language files,
added additively. The hints reuse the wizard's wiz_pass_too_short and
wiz_pass_mismatch. No new CJK glyphs, so the subset font is unchanged.
Tests: the validator rejects empty, short (7) and mismatched or
unconfirmed passphrases, and accepts 8 or more with a match. The request
gate always accepts Open, even "abc" with no confirmation, accepts
Create/Restore without a passphrase, and applies the rule to them
otherwise. An encrypted, locked wallet still opens and unlocks through
the controller with the 3-character passphrase "abc".

importKeyCore guessed the key type from its first character, then
retried a failed import with the other command. That retry is what sent
shielded keys to the backend's transparent-key decoder, which panicked
on them and poisoned the wallet lock. A WIF typo that was still
valid base58 also reached the backend unchecked.
- The key is classified first, and exactly one backend command runs, or
none:
- secret-extended-key-... and zxview... go to "import";
- a Base58Check WIF with version 0xBC or 0x80 and the compressed flag
goes to "timport";
- everything else is refused before any backend call.
There is never a retry with the other command. A testnet (0xEF) WIF
is not accepted, because the Lite app is mainnet-only.
- New fixed, untranslated reasons: "uncompressed transparent keys are
not supported by the Lite wallet", a full-node incoming viewing key
(zivks) is explained as such, and anything else is "unrecognized key
format". The key is never echoed.
- The backend's refusal while the wallet is encrypted now maps to "wallet
is encrypted - remove encryption to import a private key". It is
checked before "locked", because unlocking would not help.
- base58Decode reserves its buffers up front, and it and
decodeBase58Check wipe their copies of the decoded bytes with
sodium_memzero on every return path, since the input can be a private
key.
- exportSeed rejects the all-zero-entropy phrase (23 x "abandon" + "art").
A backend built before the seed-export fix returns it for a wallet
whose lock failed halfway (seed wiped, wallet still unlocked); it is
never a real backup and must not seed a chat identity.
- An open that the backend recovered from the .bak ("OK: recovered from
backup; damaged file kept as <name>") is written to the lite log.
Tests: the retry control now expects one "import" and no "timport", and
"typo-key" makes no backend call; the controller's transparent-import
test uses a real compressed WIF. A new classifier test covers both WIF
versions, the shielded and viewing keys, a single call on failure, the
uncompressed, zivks, testnet, bad-flag and bad-checksum refusals, the
encrypted reason and its lite-log line, the zero-entropy seed and the
recovery log line.

CMake turned every res/lang/*.json into an xxd header that i18n.cpp
compiled in as a fallback, on every platform. Only the Windows
single-file exe needs it: the Linux zip and AppImage and the macOS .app
always ship res/lang, and loadLanguage() reads the loose file first. On
Linux the embedded copy added about 1.5 MB to the binary, and every
translation edit recompiled i18n.cpp.
A new option, DRAGONX_EMBED_LANG, defaults to ON for WIN32 and OFF
elsewhere:
- ON without xxd is now a configure error (it used to warn, then fail to
compile i18n.cpp on the missing headers);
- i18n.cpp compiles the embedded includes and the fallback only when ON;
- outside Windows, loadLanguage() also tries
<exe>/../share/<app>/res/lang (the cmake --install layout and the
full-node AppImage) and <exe>/../Resources/res/lang (the macOS .app
binary run directly), so those layouts find the loose files whatever
the working directory; before, only the embedded copy covered that.
Measured:
- full-node Linux binary: .data 1,699,696 -> 168,592 bytes; stripped
19,983,136 -> 18,456,128 bytes (-1.53 MB);
- with the ImGui demo stubs, the Linux zips and AppImages are
0.50-0.55 MB smaller, with identical file lists including all 8
language files;
- a Lite build started from an unrelated working directory loads the
ja.json next to the binary (2422 strings), and the packaged Lite zip
and AppImage load ja.json with no new not-found or failed lines;
- Windows keeps the embedded copy: the 8 language headers are generated
and the ja.json bytes are in the exe.
A new test loads "de" from the loose files and checks a translated
string; with bin/res/lang moved away exactly its two assertions fail.
Behaviour changes on Linux and macOS: a missing or corrupt res/lang now
falls back to English instead of the embedded copy, and a translation
edit needs only the copy_langs step instead of a recompile.
Not verifiable here: the macOS .app in a non-English language, and the
Windows single-file exe at runtime.

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.

TruncateToWidth, the middle "front...back" ellipsis for addresses, pool
URLs, paths, labels and the status bar, cut at byte offsets: a
multi-byte character at either cut was split into invalid UTF-8 and
drawn as replacement characters (e.g. a translated Cyrillic or CJK
status). It also tried front lengths from n/2 down until one fit,
building and measuring a new string for each: up to O(n^2) per
truncated label per frame.
util::textfit::middleEllipsis keeps the same contract and is
byte-identical for ASCII, but snaps the front cut down and the back cut
up to code-point boundaries, and finds the largest fitting front length
by bisection into one reused buffer: O(log n) measures for single-line
text. Text containing a newline keeps the linear scan, because its
measured width (the widest line) does not grow steadily with the cut.
text_fit.h also gains largestFittingPrefix, a bisection over code-point
boundaries; its first caller is the node-status banner in a following
change.

The open chat thread called std::localtime at least twice per message
per frame (two day keys for grouping), and more for day separators and
time labels. On glibc every call re-checks the timezone with a stat of
/etc/localtime. The chat time helpers now use util::localTime() from
the new util/local_time.h: localtime_r (localtime_s on Windows), with
no per-call timezone check and no shared static result buffer.
glibc's localtime_r reads the timezone only once, so local_time.h also
adds util::refreshTimezone() (tzset) for caches to call when they
rebuild. Nothing calls it yet; its first caller is the chat thread's
grouping-flags cache in the next commit.

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.

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.

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.

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.

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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.

- 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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.

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.

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.

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
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.

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.

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.

Claude-Session: https://claude.ai/code/session_01BwycPDQSfEKtrTS2uC4JeT
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.

- 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.

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).

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).

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.

_popen/_popen-style shell-outs flash a cmd.exe console window on Windows. Add
Platform::runHiddenCapture() — CreateProcess + CREATE_NO_WINDOW capturing stdout on
Windows, popen on POSIX — and route the remaining shell-outs through it:
- GPU-aware idle detection (getGpuUtilization: "where nvidia-smi" / "nvidia-smi --query-gpu")
- xmrig discovery + version (findXmrigBinary "where xmrig.exe"; "<bin> --version", stderr merged)
- wallet-rebuild helper (app_network) — keeps its exit-code check via the new exitCode out-param
None of these are on the launch path (that was the daemon spawn, fixed in a2f84be); each
would flash a console only when it ran (idle-GPU mining, mining tab, wallet recovery).

- 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).

Make Merge to Address actually serve wallet-bloat consolidation and be far less
opaque. New ShieldDialog::showConsolidate() preset (used by the large-wallet
Settings banner + alert action) frames it as "Consolidate funds" and targets
shielded notes — the bloat the nudge warns about.
- Source selector: consolidate shielded notes (ANY_SAPLING), transparent
(ANY_TADDR), or both (*) — previously hardcoded to ANY_TADDR, which never
reduced the shielded-witness bloat. Batch limit now applies to the right side.
- Scope: on open, count spendable UTXOs + notes (listunspent / z_listunspent)
and show "N transparent + M shielded · ~X DRGX"; warn "repeat to finish" when
the set exceeds one batch.
- Destination auto-selects the best spendable z-address (button enabled by
default); empty wallets get an inline "Create shielded address" (z_getnewaddress).
- Advanced disclosure hides Fee + "Max inputs per batch" (renamed from the "UTXO
Limit" jargon) with sane defaults.
- Inline confirm step before the fund-moving call (amount + input count + dest).
- Live progress: self-polls z_getoperationstatus to show Consolidating… →
Done/Failed, replacing the raw opid + manual "Check status" button.
All three merge entry points now use the typed showMerge()/showConsolidate()
(no stale-static leaks from direct show(MergeToAddress)). Shield-coinbase mode
keeps working. New i18n keys fall back to English.

The BDB wallet.dat bloats with shielded-note witness data and never shrinks
in place, so a mining/shielded wallet can grow past 500 MB. Below the Wallet
Size row, show a one-line amber hint once wallet.dat crosses 500 MB with a
"Consolidate notes…" shortcut that opens the Merge to Address (z_mergetoaddress)
dialog. Full-node only (lite has no wallet.dat here); threshold is a single
named constant. i18n keys fall back to English for non-English locales.

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).

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.
