DanSandClaude Opus 4.8 90e02b1ddd feat(ui): surface daemon DEGRADED mode + v1.3.0 auto-shield status
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.

DanSandClaude Opus 4.8 ba1d760bb3 fix(autoshield): defer to the daemon's own coinbase auto-shield on v1.3.0+
v1.3.0 daemons auto-shield coinbase by default (when the HD seed is recoverable — which
every ObsidianDragon-created wallet is, via -usemnemonic=1). The wallet also ran its own
client-side auto-shield every refresh tick, so both raced for the same coinbase UTXOs and
split funds across different z-addresses (the wallet picks the first z_listaddresses entry;
the daemon uses a seed-hardened derivation).

Probe z_autoshieldstatus once per connection (while synced, so the daemon is past warmup)
and skip the wallet's client-side shield when the daemon reports it active. Fail-closed: a
pre-1.3.0 daemon has no such RPC, so the probe returns active=false and the wallet keeps
shielding — no regression on the currently-bundled v1.0.3. Re-probes on reconnect (handles
a live daemon upgrade/swap).

Follow-up (not done): drive the Settings "Auto-shield" toggle + disabled_reason from
z_autoshieldstatus (O1) — needs runtime verification of the RPC fields on a live v1.3.0 node.

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 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 06afbee4f8 fix(mining): remediate mining-tab audit (22 findings) — crash-safety, async control, validation, math
Fixes all 22 confirmed findings from the mining-tab audit (10 Medium, 12 Low; 0 Critical/High),
adversarially reviewed (6 follow-ups found + fixed, incl. the review-caught idle-auto-start bypass
and a wrong benchmark-restore condition).

Crash-safety & lifecycle:
- M-04: join a stale/finished monitor thread in XmrigManager::start() and ~XmrigManager so an xmrig
  crash-then-restart (or quit) no longer std::terminate()s the wallet.
- L-03/L-10: surface an unexpected miner exit once and clear the stale running flag.

UI never blocks (M-03/L-06/L-08/L-09/L-13): pool start/stop now run on a dedicated serialized FIFO
mining-control thread (joined before teardown), so the ~13 call sites don't block the render thread on
stop()'s SIGTERM->SIGKILL->join; the spawn result marshals back to the UI.

Miner-process / pool trust boundary:
- M-01: validate the payout address (util::isValidRecipientAddress) at EVERY start path — the UI gate
  AND App::startPoolMining() (idle auto-start / thread scaling) — so a stale/wrong-chain address can't
  silently lose rewards.
- M-09: SSRF guard skips the background pool-stats GET for loopback/private/link-local/single-label hosts.
- M-02/L-02: cap the pool-stats + xmrig-API HTTP response bodies.
- L-01: write the xmrig config 0600 at creation (POSIX open with mode) — no world/group-readable window.
- M-10: reject shell-metacharacter binary paths before the version popen (excluding '()' so Program Files
  (x86) still works).

Solo mining: M-06/M-08 clamp thread count to [1, cores] at the setgenerate/xmrig boundary; M-07 notify +
don't lie on stop failure.

Correctness: L-05 block-time constant 75->150s (chainparams); M-05 discloses pool-mode "Est. Daily" as a
rough solo-equivalent; L-04/L-11/L-12 benchmark lifecycle (cancel on nav-away / mode-switch with restore,
skip rebalance mid-benchmark); L-07 honor cancel mid-extract in both the xmrig and daemon updaters.

Two new i18n keys back-filled across all 8 languages; CJK subset font rebuilt for the new glyphs.
Verified across full-node, lite, and Windows builds; tests pass.

DanSandClaude Opus 4.8 6ee81a5abe fix: security-audit remediation (15 findings), empty-wallet warning, and send/chat/console/shutdown UX
Security audit remediation (15 confirmed findings from the codebase audit):
- H-02: scrub+delete the decrypt-flow plaintext key export on ALL exit paths
  (RAII guard) and purge stale obsidiandecryptexport* files at startup.
- M-01/L-03/L-04/L-05/L-07: sodium_memzero the Set-PIN and encrypt-PIN worker
  passphrase/PIN copies, the RPC Basic-auth string (auth_), the exported/imported
  key buffers (App::wipeSecrets, called from ~App and before main's _Exit), and
  the first-run wizard "Skip" buffers.
- M-03/M-04/M-05/L-06: return locked COPIES from XmrigManager/EmbeddedDaemon
  getters (dedicated error_mutex_; DaemonController::lastError now by value),
  route xmrig last_error_ writes through a locked setter, and wrap
  shutdown_status_/wizard_stop_status_ in a locking GuardedStatus
  (wizard_stopping_external_ -> std::atomic).
- M-02: persist after a console send/shield/import in the lite backend.
- L-01: require the confirm click for z_shieldcoinbase/z_mergetoaddress.
- L-02: quote/escape each Windows daemon argv per the MSDN CommandLineToArgvW rules.
- L-08: pin json/tomlplusplus/libwebp FetchContent to immutable commit SHAs.
- I-01: extract updater archives from the already-verified in-memory buffer
  (no disk re-read TOCTOU).

Feature: warn once (full-node) when the active wallet loads empty while a sibling
wallet file in the datadir holds keys. A funded salvage wallet.<ts>.bak routes to
the recovery/Restore flow; a funded sibling .dat routes to the wallet manager.
Per-wallet-file dismissal; gated on synced + address-list-loaded to avoid false
positives on warm reconnect / spent-down wallets.

UX fixes:
- send: show the TOTAL balance (with a spendable "available" note) in the source
  dropdown and keep pending-change addresses visible.
- chat: insert emoji at the cursor position; restrict new-chat recipients to
  shielded (z) addresses.
- console: optional auto-focus of the command input on tab open (off by default).
- shutdown: when "stop external daemon" is on, keep the shutdown screen up until
  the external node actually exits, showing live status.

Adversarially reviewed; verified across full-node, lite, and Windows builds; tests pass.

DanSandClaude Opus 4.8 5edbe8a276 feat(recovery): redesign the wallet auto-recovery flow
Turns the "Daemon Error + raw log dump" moment into one calm, honest recovery
dialog plus a recovery-aware rescan screen. Presentation + orchestration only —
the file-safety logic in rebuildWalletDatabase()/restoreOriginalWallet() (source
selection, verify-before-swap, copy/rename-never-delete, .bak) is unchanged.

- One authoritative dialog with a phase machine Offer -> Working -> Done/Failed.
  The duplicate in-overlay recovery card, the untranslated red "Daemon Error"
  heading, and the raw daemon-log dump are gone for the recovery case (they stay
  for genuine, unrelated crashes).
- Offer is a choice-cards layout: "Repair automatically" (recommended, accent-
  tinted) vs "Restore original", side by side; the rare actions ("Show me the
  files", "Decide later") and a plain-language "What happens to my files?" sit in
  a quiet footer. When the rebuild helper is missing, it collapses to a single
  Restore card — never a dead end.
- Post-repair rescan shows a calm "Finishing your wallet repair" screen with
  elapsed time + the growing wallet size, instead of "RPC timeout / taking longer
  than expected / restart daemon"; the daemon-crash toast is suppressed and the
  detection toast is downgraded from red to info.
- Fixes a confirmed dead-end: if a repair succeeds but the restarted daemon then
  crashes for a *different* reason (block index, disk, OOM), the recovery flags
  now clear (in tryConnect + onConnected) so it surfaces as a normal daemon
  failure instead of freezing forever on a reassuring "don't restart" screen.
- Clickable "Wallet repair available" status-bar chip for re-entry.

The same app.cpp changes HiDPI-harden the surfaces the recovery flow lives on:
the status-bar and loading-overlay hand-drawn geometry are multiplied by dpiScale
(they rendered native-size and clipped at HiDPI / font_scale>1), the loading-
overlay status text wraps instead of running off both edges, and the node-status
banner floors its height to its DPI-baked font so the title can't clip off the top.

DanSandClaude Opus 4.8 3216debc7d fix(node): detect a wallet salvage at startup, not only on connect
Reported: loading a BDB-inconsistent wallet silently renamed it and created a new
one — no recovery dialog. Two causes, both fixed:

1) Detection ran only in onConnected(). The salvage happens at STARTUP, and the
   node may never connect (block-index abort, long sync, crash) — or a long sync
   trims the salvage line out of the rolling output buffer before connect. Extract
   detectWalletAutoRecovery() and run it every tryConnect() tick (every ~5s during
   startup), so the salvage is caught the instant it appears, regardless of whether
   the node connects. Also hold the crash-restart loop while a salvage is pending,
   so the wallet can't be re-salvaged/shrunk while the Rebuild/Restore dialog is up.

2) walletAutoRecovered() only matched the SUCCESSFUL-salvage strings. A
   BDB-inconsistent file makes aggressive salvage FAIL ("found no records"), which
   prints different lines. Broaden the detector to the signals that fire in every
   case: "CDBEnv::Salvage", the "Renamed <wallet> to wallet.<ts>.bak" rename, and
   "found no records in wallet" — while still not matching normal startup or a
   block-DB abort.

Adds the exact failed-salvage sequence to the detector test. Build clean, suite
green (1/1).

DanSandClaude Opus 4.8 bc183257b7 feat(node): in-app "Rebuild wallet database" recovery for a BDB-inconsistent wallet
Automates the manual recovery that fixed a wallet.dat with stale Berkeley DB
extent metadata (the "main" subdb metapage records a low last_pgno while its live
data spans thousands of pages beyond it). A tolerant page-walk reads every record,
but the daemon's BDB verify rejects the file and auto-salvages it — finding nothing
and shrinking the wallet to empty on each restart (the salvage cascade that looks
like fund loss). Plain "Restore original" can't fix it (hands the same broken file
back → re-salvage); a rebuild must produce a fresh, consistent DB.

Pieces (Approach A from the design workflow — out-of-process helper keeps AGPL
Berkeley DB out of the GPLv3 GUI):
- util/wallet_file_probe.h: extractWalletBtreeRecords() — sibling to parseWalletBtree
  that collects raw (key,value) bytes (same bounds-checked, subdb-aware walk).
  Records copied verbatim → encrypted key material passes through as opaque
  ciphertext (no passphrase). Overflow-page values (only large tx history) are
  skipped + counted; a rescan rebuilds history — funds unaffected.
- tools/wallet_rebuild/main.cpp: dragonx-wallet-rebuild CLI — reads via the tolerant
  reader, writes the records into a fresh BDB "main" btree via libdb (DB_EXCL, never
  overwrites), prints a JSON summary. New BDB-guarded CMake target.
- App::rebuildWalletDatabase(): picks the largest readable wallet/.bak as source,
  stops the daemon, runs the helper, VERIFIES the output (readable BDB with keys)
  before swapping, moves the current wallet aside (kept, timestamped), installs the
  rebuilt one, clears the stale BDB env, sets -rescan, restarts. Copy/rename only —
  never deletes. Result surfaced via the existing pumpWalletRestore channel.
- Wired as the preferred action on the existing wallet-auto-recovery dialog
  (shown only when the helper is present). Full-node only; lite-safe.

Verified end-to-end against the real broken wallet: helper reads 3,808 t-keys + 1
z-key + HD seed and the daemon LOADS the rebuilt output with no salvage. Adds
extractWalletBtreeRecords coverage. Build clean, suite green (1/1).

Remaining (follow-up): release packaging — build.sh bundling the helper built
against the vendored per-platform static libdb (DRAGONX_BDB_ROOT), and a macOS
Berkeley DB port (no in-tree artifact).

DanSandClaude Opus 4.8 384d64ea5d feat(node): one-click "Restore original wallet" after a daemon auto-recovery
Adds the restore action to the wallet-auto-recovery warning: undo the daemon's
salvage by swapping the untouched original (wallet.<ts>.bak) back over the
salvaged copy and clearing the stale BDB env that triggered the false recovery,
then restarting. Modeled on beginAdoptSeedWallet (stop daemon → file ops →
restart on a worker; result pumped to the main thread for notifications).

Safety (fund-adjacent file ops on a real wallet — copy/rename only, never delete
user data):
- picks the newest wallet.<unixtime>.bak via the pure, unit-tested
  newestWalletSalvageBak(); aborts if none.
- verifies the .bak is a real Berkeley DB (probeWalletFile) before touching
  anything — won't overwrite a working wallet with a bad backup.
- stops the daemon first (stopDaemonForWalletSwitch) so wallet.dat is released.
- moves the salvaged copy aside to wallet.dat.salvaged-<ts>.dat (kept), COPIES
  the .bak into place (the .bak stays), moves database/ aside to
  database.pre-restore-<ts>.bak (kept), and drops only the transient __db.*
  BDB region files. Rolls back the move if the copy fails.
- relaunches the node even on failure so it's never left down.

The warning dialog now offers Restore original wallet / Open data folder /
Keep salvaged copy. Full-node only; lite-safe. Build clean, suite green (1/1).

DanSandClaude Opus 4.8 3b7423f3a1 feat(node): warn when the daemon auto-recovers (salvages) wallet.dat
dragonxd auto-recovers a wallet.dat that fails BDB verification on startup — no
flag needed (CWallet::Verify → CDBEnv::Verify(walletFile, CWalletDB::Recover)):
it moves the original to wallet.<timestamp>.bak, salvages readable keys into a
fresh wallet.dat, and keeps running. The salvage can be incomplete (or the whole
thing a FALSE POSITIVE from stale/cross-platform BDB env state — __db.* / the
database/ dir carried between machines), so the node silently comes up on a
possibly-empty wallet. To the user that reads as fund loss, with no warning.

Detect it and warn loudly instead:
- daemon/daemon_startup_diagnosis.h: pure walletAutoRecovered() (the salvage /
  "Original wallet.dat saved as wallet.<ts>.bak" markers) + newestWalletSalvageBak()
  (picks the wallet.<unixtime>.bak the recovery just made).
- onConnected() scans the node's captured output once per session; on a match it
  shows a warning dialog + notification: the ORIGINAL is safe in wallet.<ts>.bak,
  the shown balance may be incomplete, and here are the exact steps to restore it
  (rename the .bak back + delete the stale database/ + __db.* env). One-click
  "Open data folder" jumps straight there. Full-node only; lite-safe.

Deliberately does NOT auto-swap the wallet files (untested per-platform file
manipulation on a real wallet is not worth the risk) — it informs + guides.

Adds walletAutoRecovered / newestWalletSalvageBak coverage to
testBlockDbOutputDiagnosis. Suite green (1/1).

DanSandClaude Opus 4.8 d136916e80 feat(node): detect an unreadable block DB on startup and offer a one-click reindex
When a daemon update changes the block-index on-disk format (or the index is
corrupt), dragonxd aborts at startup — "non-canonical optional discriminant" →
"Error loading block database. Aborted." — and the wallet silently shows a zero
balance. Previously the connect loop just crash-restarted into the same abort up
to 3x and then reported a bare "Daemon crashed N times", with no path forward.

Now:
- daemon/daemon_startup_diagnosis.h: pure blockDbOutputLooksBroken() classifies
  the crashed node's captured console output (the fatal block-DB markers).
- The connect loop detects it on the FIRST abort, STOPS crash-restarting into the
  same failure (each retry reloads the whole index — wasteful), and offers a fix.
- A one-shot -reindex flag (EmbeddedDaemon::setReindexOnNextStart → DaemonController
  forwarder → args) rebuilds the block index + chainstate from the intact raw
  blocks; App::reindexBlockDatabase() arms it and un-gates the loop to restart.
- An auto-shown dialog (renderBlockDbReindexDialog) + a notification explain the
  situation ("your coins are safe; the node just can't load the chain") and offer
  a one-click "Rebuild block database". Full-node only (gated), lite-safe.

This is the exact trap behind a real "big wallet shows no funds" report: a
post-format-change daemon over pre-change chaindata. Reindex also fixes a plain
corrupt index.

Adds testBlockDbOutputDiagnosis (the abort sequence + individual markers trip it;
normal startup / wallet-corruption / asmap errors do not). Suite green (1/1).

DanSandClaude Opus 4.8 32be868dbc feat(migrate): persist the sweep opid so a mid-sweep interruption can resume (W3-3)
Migrate-to-seed submits z_mergetoaddress -> an async opid, then only persists the resolved
txid once the op completes. An app-close during Sweeping (opid submitted, txid not yet
resolved) dropped the opid and resumed at the re-sweep gate, silently losing the tx.

Now the opid is persisted and re-tracked on resume. If the daemon forgot it (restart —
its op queue is in-memory only), the existing poller flags it stale and the callback falls
back to the dismissable Sweep gate; it can never hang (a thrown RPC aborts the poll, so a
stale classification only comes from a *successful* poll that omits the opid).

- New seed_migration_sweep_opid setting; adopted atomically with clearing any prior txid in
  the SAME settings.save(), and only once the submit succeeds — so a failed "Sweep remaining"
  re-sweep keeps the already-mined first sweep's Confirming context, and txid/opid are never
  both authoritative (resume checks txid first; torn-write safe).
- Resume routing extracted to a pure, unit-tested helper
  (data/seed_migration_resume.h::decideSeedMigrationResume): txid -> Confirming; opid AND
  connected -> re-track (Sweeping); else -> the dismissable Sweep gate. The connectivity gate
  keeps a disconnected resume out of the buttonless Sweeping spinner.
- Shared makeSweepCompletionCallback(resumed): success -> Confirming; resumed-stale -> Sweep
  gate (re-fetch balance + "may have already completed" copy); fresh-fail -> Error.

Fund safety unchanged: adopt still gated on legacy balance ~0 AND sweep tx mined; legacy
wallet.dat only ever moved to a never-deleted timestamped .bak.

Reviewed in two adversarial rounds (design + implementation) per the migration-code mandate;
both safety facts (no fund loss, no hang) held, and the resume-UX traps they surfaced are
fixed. Build-clean; ctest 1/1 (adds testSeedMigrationResume). See docs/wallet-hardening.md.

*** Still requires a live mainnet interrupted-sweep run before release (human gate). ***

DanSandClaude Opus 4.8 4b3f0fa92b feat(diagnostics): persistent alert history with a status-bar bell (Foundation QoL)
Toasts fade in 1-4s, so anything that scrolled past was gone. Notifications now retains
every pushed alert in a capped (100) ring buffer with a wall-clock epoch (AlertRecord) —
separate from the 5-item live-toast deque — plus a monotonic total_pushed_ counter.

A bell in the status-bar right cluster opens an upward popup listing recent alerts
newest-first: severity icon + colour (reusing the toast palette), the message, and a
relative age (formatTimeAgoShort), with a Clear-all action. An unread dot on the bell,
coloured by the most-severe unseen alert, marks alerts that arrived since the panel was
last opened — driven by totalPushed() deltas so it survives capping/clearing.

Thread note: every push is on the UI thread (RPC results run as main-thread MainCb
callbacks), matching this class's existing lock-free model; documented as a
no-raw-worker-thread invariant.

New i18n keys (alerts_*). Build-clean; ctest 1/1 (adds testNotificationHistory: retention,
order, cap, monotonic counter, clear). Closes the QoL bundle and the Foundation tier.

DanSandClaude Opus 4.8 e779ded2e8 feat(diagnostics): persistent node/RPC error banner at top of content (Foundation QoL)
A persistent horizontal strip now appears at the top of the content column whenever the
wallet can't reach its node — unlike the transient toasts it stays up for as long as the
fault persists, so an offline wallet is never silently mistaken for a working one.

The show/severity/action decision is a pure, unit-tested function
(ui/node_status_banner.h::evaluateNodeStatusBanner) fed a state snapshot by the new
App::renderNodeStatusBanner(). Three cases:
  - full-node offline        -> amber, "Reconnect"    (App::tryConnect)
  - embedded daemon crashed
    & auto-restart gave up    -> red,   "Restart node" (App::restartDaemon)
  - lite wallet open failed   -> red,   message-only

Suppressed during the wizard / wallet-switch / daemon-restart / screenshot-sweep / shutdown,
and while an expected startup phase (warmup / init / connect-in-progress) already owns the
screen. Banner height lives in res/themes/ui.toml (banners.node-status); colours come from the
material semantic palette; the detail text is ellipsis-clipped so it can't push the action
button off-screen. Drawn before the content edge-fade vertex capture so it stays fully opaque.

New i18n keys (node_banner_*). Build-clean both variants; ctest 1/1 (adds testNodeStatusBanner).

DanSandClaude Opus 4.8 940dd21464 feat(diagnostics): add "Copy diagnostics" + "Open log folder" actions (Foundation QoL)
Settings (logging section) gains two support-friendly actions, now that the logging
foundation actually produces logs (W7-2):

- Open log folder: opens the config dir (Platform::openFolder) so users can find
  dragonx-debug.log / dragonx-crash.log.

- Copy diagnostics: copies a plaintext support snapshot to the clipboard via the new
  App::buildDiagnosticsReport() — version, build variant, platform, connection status,
  active wallet path + existence + size, encryption/lock state, sync heights, and (full-
  node) daemon status/running/crash-count/lastError, plus the log paths. No secrets.

Build-clean; ctest 1/1. Remaining QoL: persistent alert history, a daemon/RPC error
banner, and the W6-2 refresh-staleness badge. See docs/wallet-hardening.md.

DanSandClaude Opus 4.8 8c12b27c0a fix(security): don't silently leave a wallet unencrypted or unlocked (W2-2, W2-4)
P0-B encryption-integrity cluster.

W2-2: the first-run wizard's "encrypt" stored the passphrase only in memory and let the
user into the app immediately, so a quit/crash or a failed daemon connect before the
deferred encryption applied left the wallet unencrypted with NO record encryption was
ever requested — the user believing it was encrypted. A persisted encryption_pending
settings flag is now set the moment encryption is requested (never the passphrase, only
the fact). refreshWalletEncryptionState() reconciles it on every connect: wallet observed
encrypted -> clear the flag; wallet NOT encrypted while the flag is set and no deferred
encryption is pending/in-flight -> a once-per-session "your wallet is NOT encrypted — open
Settings to finish" warning (the flag stays set, so it recurs each launch until resolved).
The passphrase is deliberately never persisted to auto-complete — surfacing it is the
secure choice.

W2-4: lockWallet()'s continuation only handled success — a failed walletlock RPC silently
left the wallet UNLOCKED (an unfulfilled auto-lock). It now logs and warns once (reset on
the next successful lock) so a failing auto-lock is visible instead of leaving the wallet
exposed.

Touches settings.{h,cpp}, app_wizard.cpp, app_security.cpp, app.h. Not unit-testable at
this layer (RPC/connect-driven state). Build-clean; ctest 1/1. See docs/wallet-hardening.md.

DanSandClaude Opus 4.8 eb69e491b9 fix(startup): surface a "taking too long" notice when the daemon won't come up
F3: the daemon connect loop retried forever with only an animated spinner when the
daemon was reachable-but-never-ready (stuck in RPC warmup / -28, or an external daemon
that never finishes init) -- no error, no guidance, no escape. It now stamps
connect_stall_since_ the moment the daemon first goes "reachable but not ready" (the
warmup branch + applyDaemonInitStatus) and clears it on connect / disconnect /
warmup-complete. A pure, unit-testable util::connectHasStalled() helper (new
util/connect_stall.h, 45s default from ui.toml [screens.loading].stall-timeout-sec)
drives a "Taking longer than expected" notice in renderLoadingOverlay(): a title, a
reassuring body with elapsed seconds, and a full-node hint to Settings > Restart Daemon
or the Console. The background retry keeps running underneath, so the notice self-clears
the instant it connects. Guarded off while the daemon is in State::Error (that case is
owned by the existing crash-count hint).

The overlay is a pure draw-list layer with no interactive widgets, so this follows the
existing crash-hint idiom (guidance text, not injected buttons); the stalled state is
computed locally in the overlay, so the only new App member is connect_stall_since_.

Adds testConnectHasStalled to test_phase4.cpp and three i18n keys to i18n.cpp (English
source of truth; the res/lang/*.json back-fill is deferred to a single
add_missing_translations.py run at the end of the batch).

DanSandClaude Fable 5 bcee4bfe72 fix(security): apply audit remediations to dev (ported + dev-only)
Dev-branch audit (docs/_archive/security-audit-dev-2026-07-22.md) re-found the
master issues (absent on dev) plus new ones in dev-only code. Applied here;
full-node build + test suite green; the subtle fixes were adversarially re-verified.

Ported from the master remediation (adapted to dev's code):
- bootstrap: reject zip-slip / path-traversal archive members (isSafeArchivePath)
  before writing (S2-1). (dev already fail-closes on a missing checksum.)
- xmrig updater: fail closed when a signature is required but no key is pinned (F1-1).
- http_download.httpGetString: 16 MiB hard cap + MAXFILESIZE on the shared
  metadata/price fetch (F1-2 / caps the updater + exchange paths at one site).
- rpc_client: explicit SSL_VERIFYPEER/VERIFYHOST (F4-1) and a 256 MiB response
  cap in WriteCallback (F4-3).
- lite_connection_service: reject remote http:// lite servers, loopback only (L1-1).
  Loopback is matched by a strict dotted-decimal 127.0.0.0/8 check (not a
  startsWith("127.") prefix, which would wrongly accept 127.0.0.1.evil.com), with
  userinfo/fragment stripping.
- lite controller: propagate encrypt/decrypt save() failure instead of reporting
  success (F7-1).
- xmrig_manager: chmod(0600) the pool config before writing secrets (F5-2).
- app: clear the copied secret from the OS clipboard on shutdown (F3b-1).
- export_transactions: neutralize CSV/spreadsheet formula injection (F13-1).
- build pipeline: build-from-source lite backend + remove the self-attested
  CMake signature gate (F15-1); pinned+verified appimagetool (F15-3/4);
  verified Sapling params in setup.sh (F15-6); build.sh exits 0 on success.
  (F14-1 empty-quoted-arg and F8-2 NUL-termination were already fixed on dev.)

Dev-only findings:
- rpc_client.callRaw: scrub the raw buffer + parsed tree (templated scrubJsonSecrets
  for ordered_json) so console dumpprivkey/z_exportkey keys don't linger in freed
  heap (N1-1).
- seed_wallet_creator: wipe the exported mnemonic on the failure path so a discarded
  failed result never carries a live seed (W1-2).
- export_all_keys: write the plaintext key dump 0600 + atomically via
  writeFileAtomically (U1-2).
- chat_database: restrict chat_messages.sqlite and its WAL/SHM sidecars to owner-only (C3-1).

Not done (need a decision, documented in the report):
- Chat header metadata (cid/z/p) rides outside the AEAD (C1/C2) — binding it is a
  wire-protocol change requiring SilentDragonXLite interop review.
- Bootstrap lacks an offline-rooted signature (S2-2 residual) — needs signing infra.
- Console scrollback retains console-typed key-export output in plaintext (N1-1
  residual) — inherent to an echoing console; would need output redaction.

DanSandClaude Opus 4.8 203967411a feat(chat): theme the :drgx: emoji to the accent (was fixed brand colors)
The custom DragonX chat emoji now recolors to the theme like the logo — body =
accent, detail = white on dark skins / on-surface (dark) on light skins — and
re-rasterizes on a theme/dark-light change (moved out of the one-time fixed-color
load into ensureLogoTexture's re-render block). The detail highlights keep it
legible even on accent-tinted outgoing bubbles.

DanSandClaude Opus 4.8 3a2be661ea feat(chat): custom DragonX emoji via the :drgx: shortcode
Add a DragonX custom emoji to chat. The emoji picker gains a DragonX tile (first
cell) that inserts the text ":drgx:"; message bodies containing it render the mark
inline via layoutChatBodyRich, which flows text words + the emoji image with word
wrap (plain bodies keep the tighter layoutChatBody path, so normal messages are
unaffected). Other clients simply show the literal ":drgx:" text — a portable
encoding with graceful degradation.

The emoji is the DragonX SVG rasterized once at fixed brand colors (crimson body,
white detail) via LoadTextureFromSvg — theme-independent so it looks identical for
sender and receiver — exposed as App::getDrgxEmojiTexture(). Emoji insertion is
factored into one insertToken() helper (space-prepend + on-chain byte cap), shared
by the DragonX tile and the Unicode emojis. Drag-to-select text is skipped on
":drgx:" messages (their inline layout doesn't match the plain-text hit-test
geometry); right-click "copy" still copies the whole message.

DanSandClaude Opus 4.8 17525003c5 feat(ui): themed DragonX logo — runtime-rasterized SVG recolored per skin
Replace the shared app logo (Overview header, first-run wizard, lock screen) with
the DragonX mark rendered from res/img/logos/logo_dragonx.svg, recolored to each
theme: the dragon body takes the theme accent (Primary()), the inner detail stays
light. Vendor nanosvg (memononen, zlib/public-domain) in libs/nanosvg/ and add
util::LoadTextureFromSvg (parse a copy, recolor shapes by luminance, rasterize to
RGBA, upload via the existing CreateRawTexture — GL + DX11). The SVG is embedded as
a string (src/embedded/logo_dragonx_svg.h) so it's available in every build.

The load moves into App::ensureLogoTexture(), called at the top of render() BEFORE
the wizard/lock early-returns (so those screens get the logo too, which they never
did before), and re-rasterizes when the accent or the dark/light variant changes.
The per-skin PNG remains a fallback if rasterization ever fails; logo-texture
lifetime is now freed on replace + on theme switch (was leaked).

DanSandClaude Opus 4.8 b0a4333cdf feat(chat): pre-split note buffer for rapid sends + status + console logging
Each chat message is a shielded tx that spends a verified note, so a burst of
messages hit "insufficient verified funds" once the single note is spent. Add a
per-frame note-buffer coordinator (both variants) that keeps ~10 verified
spendable notes: it serializes sends through the one broadcast channel, counts
verified notes by block depth (lite) or a rate-limited z_listunspent scan
(full node), self-splits in the background to refill toward the target, and
queues overflow to drain as change matures — with honest Sent/Failed status
instead of the prior optimistic "Sent". Guardrails: single split in flight with
a watchdog, cooldown, and session-generation guards so a wallet switch can't
drain another wallet's queue. Surface a "Chat buffer: N/10 ready" indicator in
the status bar while the Chat tab is active, and route chat diagnostics through
the console on both variants (the full-node console now drains the shared ring).

DanSandClaude Opus 4.8 125ffa8863 feat(chat): dedicated ~2.5s poll for the 0-conf fast-scan
The fast-scan was hung on the page's Transactions timer, which is 10–15s on most
pages (15s on Chat), so incoming messages still took up to ~15s to appear. Give it
its own ~2.5s accumulator (delta-time based, independent of the page cadence) so
messages land in a few seconds — network propagation then dominates, which is as
fast as 0-conf gets. Still gated behind the warmup/rescan block and self-gated in
fastScanChatMemos; the in-flight guard prevents overlapping RPCs.

DanSandClaude Opus 4.8 30bd0d99ff feat(chat): 0-conf fast-scan so incoming messages show before a block
The receive harvest gates each z-address behind scannedAtTip — it only re-scans
when a new block advances the tip — so incoming chat waited ~1 confirmation even
though the daemon already exposes mempool notes (FindMySaplingNotes runs on
mempool txs; z_listreceivedbyaddress(addr,0) returns them).

Add App::fastScanChatMemos(): every transaction-refresh cycle, re-scan JUST the
chat reply address (where peers send) at minconf=0, extract chat metadata, and
ingest — so messages surface at mempool speed (a few seconds) instead of waiting
for a block. Full-node only (lite has its own harvest). An in-flight guard avoids
stacking RPCs; the store dedups on txid+position, so the confirmed harvest never
double-inserts.

Hidden conversations are deliberately skipped by the fast path — they don't get
the mempool speed-up and still come back through the normal confirmed harvest
(which un-hides on a new message). New non-muted messages toast off-tab as usual.

DanSandClaude Opus 4.8 76093fe82d fix(chat): address adversarial review of the send-path change
Four confirmed findings from the review of ef247c9:

1. Persistence regression — the deferred-persist echo (in-memory Sending, written
   only when the async callback resolved) meant a message broadcast on-chain but
   whose callback hadn't fired yet was LOST from history if the app quit/crashed
   in that window. Persist the echo immediately as Sending and UPSERT the final
   status on resolve (new ChatDatabase::upsert with ON CONFLICT DO UPDATE, since
   append is INSERT-OR-IGNORE). A stray persisted Sending still loads as Sent.

2. Fee ceiling — dragonxd REJECTS a 0-value tx whose fee exceeds the default
   miners fee (0.0001), and max(getDefaultFee(), 0.0001) can only raise it, so a
   default_fee > 0.0001 broke every chat send. Pin chat to exactly kChatMinFeeDrgx,
   dropping getDefaultFee() from this path (chat always moves 0 value).

3. Lifetime — the resolve callback had no generation guard, so a wallet lock (which
   doesn't disconnect) between submit and callback could resolve against a cleared
   store. Capture chat_session_generation_ and bail on mismatch (both the full-node
   callback and the lite optimistic resolve), matching the identity-fetch pattern.

4. Retry misdirect — Retry on a failed CONTACT REQUEST called sendChatMessage,
   which (no peer key yet) just showed "waiting for reply". Route it to
   sendContactRequestForCid() (refactored out of startChatConversation) so it
   re-sends the request into the SAME conversation.

DanSandClaude Opus 4.8 ef247c95ff feat(chat): fee floor, real delivery status, pay-from-funded, funds pre-check
Chat sends move 0 value, so the network fee is structurally load-bearing (it's
the only thing that forces a real shielded input; 0-value + 0-fee builds a
degenerate, unrelayable tx). Three gaps addressed:

1. Fee floor — broadcastChatMemos now uses max(getDefaultFee(), kChatMinFeeDrgx),
   so a 0 / too-low global default-fee setting can't silently break chat.

2. Real delivery status — the echo was marked Sent on SUBMIT regardless of the
   on-chain outcome (the z_sendmany callback was empty), so failures were
   invisible and the Retry affordance never fired for async failures. Add a third
   ChatDelivery::Sending state (appended so persisted 0=Sent stays valid); record
   the echo in-memory as Sending, and resolve it to Sent/Failed from the
   z_sendmany completion callback — persisting only the final status (so a restart
   never shows a stuck spinner; a stray persisted Sending loads as Sent). A subtle
   "sending…" label shows while in flight.

3. Pay-from-funded + pre-check — z_sendmany spends from one z-address, and the
   identity reply address may be unfunded while funds sit elsewhere. chatPayFromZaddr
   picks a spendable z-address that can cover the fee (preferring the identity
   address); the memo still advertises the identity address as reply-to, so paying
   from a different note is transport-transparent. If nothing can cover the fee, a
   clear "need a small shielded balance" toast replaces the cryptic failure.

Full node only for the callback path; lite resolves optimistically on queue.
8-language strings + CJK subset (+1 glyph 賄).

DanSandClaude Opus 4.8 2072f70a60 fix(contacts): stable per-wallet scope so contacts don't vanish (address-hash drift)
Contacts were scoped by activeWalletIdentityHash() — a hash of the wallet's
ENTIRE address set. Creating a new receive address grows the set, changing the
hash, so every contact stamped with the old hash falls out of the scope filter
(contacts_tab.cpp:915) while still being counted — the "3 saved, 1 showing"
symptom, where only the one set to global (which bypasses the scope) survives.
It also hid scoped contacts on every startup before the daemon connected (hash
empty until addresses load).

Introduce a stable per-wallet scope id: WalletIndexEntry.scopeId ("w:"+random
hex), generated once and persisted in the wallet index (keyed by wallet file),
never recomputed from the mutable address set — so creating addresses, locking,
or disconnecting never changes it. App::activeWalletScopeId() establishes it on
first use. Contacts now scope + filter on this instead of the drifting hash. The
tx-history-cache identity (the hash's real purpose) is untouched.

Recovery for already-orphaned contacts:
- AddressBook::reattachLegacyScopes() re-attaches non-global, non-"w:" contacts
  to the active wallet's stable id; run once when there's a single known wallet
  (unambiguous attribution). Idempotent.
- The scope filter fails OPEN for legacy scopes (multi-wallet case where recovery
  can't attribute them) so no contact is ever hidden; stable "w:" scopes still
  match strictly.

Track a per-conversation "last seen" watermark (message timestamp) on App:
- chatUnreadCount() sums incoming messages newer than each conversation's
  watermark; surfaced as SidebarStatus.chatUnreadCount → a badge on the Chat nav
  item (mirrors the History/Peers badges).
- Viewing a thread marks it seen (markChatConversationSeen while displayed).
- Baseline on load: existing stored messages are marked seen, so only messages
  that arrive while the app is open badge as unread.
- Wiped in resetChatSession so unread state never leaks across a wallet switch.
In-memory only (resets on app restart); persistence is a later refinement.

DanSandClaude Opus 4.8 d9911a9bc9 feat(wallet): detect a corrupt target wallet on switch + offer -salvagewallet repair
When a switch fails, the failure modal now distinguishes a CORRUPT target wallet
from other failures and offers a one-click repair:
- The switch worker watermarks the node's captured console output before the
  start and, if the node dies in init, scans this start's output for a corruption
  signature ("Failed to rename … .bak" / "salvage failed" / "wallet.dat corrupt" /
  "Error loading wallet") → sets switch_wallet_corrupt_.
- The Failed modal then shows an accurate "this wallet appears corrupt" message
  (instead of the generic "Couldn't open that wallet") plus a "Try to repair
  (salvage)" button that retries the switch with the target node started under
  -salvagewallet (recovers readable keypairs; implies -rescan).
- EmbeddedDaemon::setSalvageOnNextStart (one-shot, precedence salvage > zap >
  rescan) + controller forwarder; switchToWallet gains a salvage arg.

Salvage operates only on the corrupt target (never the good wallet, no fund
movement). Adversarially verified: output isolation, one-shot lifecycle, state
handling, re-entrancy, no success-path regression.

The switch modal now shows more than a bare phase line:
- The title carries the target wallet ("Switching wallet — savings") and a
  "from <previous>" caption for context (names prettified: wallet.dat → "Default
  wallet", wallet-<name>.dat → "<name>", in-place links → "External wallet").
- During the Reconnecting phase — the ~30-60s where the node loads the block
  index, verifies, and rescans — it surfaces the node's LIVE init stage
  (state_.warmup_status/description via the existing translateWarmup mapping:
  "Loading blockchain data…", "Verifying blockchain…", "Scanning for
  transactions…") instead of a static "Reconnecting…".
- An elapsed timer (m:ss) so the wait visibly progresses.

DanSandClaude Opus 4.8 88091bd77c feat(wallet): live progress modal for wallet switching
The "Stop the running node?" confirm modal now stays open through the entire
switch — stop → wait-for-exit → start → reconnect — showing a live phase, and
auto-closes the moment the new node connects. This turns the up-to-a-minute
graceful-shutdown wait from an apparent freeze into visible progress.

- WalletSwitchPhase (Stopping/Starting/Reconnecting/Failed) + atomic phase and
  dialog-open flags; the worker advances the phase, onConnected closes the modal,
  and a failed switch shows the accurate reason with a Close button.
- Owned switches (no confirm) also show the progress modal directly.
- "Continue in background" escape hatch so a long rescan / a hung startup never
  traps the user (the switch keeps running; a toast reports the result).
- isWalletSwitchInProgress() keeps the frame loop redrawing so the phase text and
  spinner animate while otherwise idle.
- i18n (EN + 8 languages, additive) + a modal-switch-progress sweep surface.

State machine adversarially verified 6/6 (thread-safety, no stuck modal,
confirm→progress transition, owned/unowned, no phase leak, redraw scoping).

DanSandClaude Opus 4.8 42d59709f9 feat(wallet): confirm before stopping an adopted node to switch wallets
When switching wallets, the node the app would restart may be one this session
ADOPTED — a dragonxd already running at launch (left up by "keep node running",
or started by the user). Rather than stopping it silently (or the old dead-code
"stop any external dragonxd first" refusal), show a "Stop the running node?"
confirmation first; switching then stops it (RPC stop + wait for the port to
fully free) and relaunches on the selected wallet.

- switchToWallet(walletFile, stopDaemonConfirmed=false): when the node is adopted
  (externalDaemonDetected) and not yet confirmed, defer to the dialog and return.
- renderSwitchStopDaemonDialog(): BlurFloat overlay (house style) with a warning
  header; confirm re-enters switchToWallet(w, true); cancel/X aborts, node keeps
  running. Owned nodes (started this session) still restart silently.
- i18n (EN + 8 languages, additive) + CJK subset rebuild; modal-switch-stopnode
  sweep surface for visual review.

Gate/re-entrancy adversarially verified (no state leak; owned switches ungated;
prompt reappears on a reverted switch; dead-daemon-before-confirm handled).

DanSandClaude Opus 4.8 3808b3ee82 fix(wallet): let a switch restart an adopted (external) daemon
Switching to a named wallet failed every time when the app had connected to a
pre-existing dragonxd at startup: the daemon is flagged externalDaemonDetected,
so stopEmbeddedDaemon()'s policy is DisconnectOnly ("not ours to stop") and the
switch skips the stop entirely. The old daemon keeps the RPC port, and the
relaunch fast-fails on EmbeddedDaemon::start()'s isPortInUse check — misread as a
bad wallet, reverting after a ~40s hang on the process-handle-only run-wait
(which reads false immediately for an adopted daemon).

A switch legitimately needs to restart the node, so:
- App::stopDaemonForWalletSwitch(): for an adopted daemon, send a graceful RPC
  "stop" using the creds we actually connected with (saved_config_) — only our
  own daemon obeys it, so a foreign dragonxd is a safe no-op — then wait (bounded
  ~40s) for the RPC port to actually free (isRpcPortInUse, the same gate start()
  uses). Owned daemons take the normal stopEmbeddedDaemon() path. No PID/name kill
  is ever issued at an adopted daemon.
- switchToWallet: gate start() on the port actually freeing; if it doesn't,
  abort with a distinct switch_stop_failed_ reason instead of starting into a busy
  port. Clear the external latch before relaunch so the fresh process is owned.
- EmbeddedDaemon::clearExternalDaemonDetected() (+ controller forwarder).
- Accurate revert message: "the running node didn't release its connection in
  time" vs. the bad-wallet message.

Root-caused from live Windows logs; design + implementation adversarially
verified. Note: beginAdoptSeedWallet has the identical pattern and is left for a
separate fund-critical review.

mnemonic DB record — the mnemonic is derived from the HD seed), so a legacy HD
wallet was shown as "Seed phrase".

For the ACTIVE wallet the app already knows the truth at runtime via
z_exportmnemonic (wallet_seed_status_). The active row's badge now uses that
authoritative status (activeWalletSeedBadge: seed-phrase / legacy / undecided)
and only falls back to the probe for non-active or not-yet-decided wallets; the
"unknown" seed badge is suppressed once the runtime status is authoritative.

DanSandClaude Opus 4.8 928335dd6b fix(wallet-switch): late-fail revert, shutdown-freeze, per-wallet PIN gate
The two deferred audit MEDs + the per-wallet PIN follow-up:

- Late-init failure revert (MED): the 1.5s start grace only catches a wallet that
  fails IMMEDIATELY. A wallet that fails LATE in dragonxd init (past the grace)
  used to persist as a broken active_wallet_file. Now a switch stays
  "pending confirm" until the daemon actually connects (onConnected clears it);
  if the connect loop instead hits the crash-wedge (crashCount >= 3) while a
  switch is pending, it flags the main-thread revert (which also resets the crash
  count so the restored wallet can start).
- Shutdown freeze (MED): the switch worker's 30s daemon-stop wait now breaks
  promptly when shutdown starts, so beginShutdown's join of the switch task can't
  freeze the UI for the full 30s (shutdown stops the daemon itself). The seed-
  adopt task is intentionally left to finish (fund-safety), as before.
- Per-wallet PIN (follow-up): App::hasPinVault() (and the lock-screen path) now
  gate on the per-wallet vault presence alone, not the GLOBAL getPinEnabled flag —
  so disabling PIN on one wallet no longer suppresses another wallet's PIN
  quick-unlock after a switch.

DanSandClaude Opus 4.8 63dcda0ad1 fix(wallet-switch): close gaps found verifying clusters A/B/C
Adversarial verification of the audit fixes found real gaps in them:

- HIGH throw-safety: the switch worker and the encryption-restart worker set
  daemon_restarting_=true but reset it only on their normal/early-return paths —
  a throw from stop/startEmbeddedDaemon left the flag stuck true, wedging
  reconnect and every future switch/rescan/encryption. Both now reset it on all
  paths (try/catch); a throw during a switch is treated as a failed switch and
  triggers the revert.
- HIGH residual chat leak: resetChatSession() cleared the flags but an already-
  posted z_exportmnemonic worker job still held wallet A's secret, and its
  completion callback (guarded only by isLocked(), false for an unencrypted
  wallet) would provision A's identity under B. Add a chat_session_generation_
  epoch bumped on every wallet change; the fetch captures it and its callback
  discards the (previous-wallet) secret if the epoch no longer matches.
- LOW vault-scope collision: the per-wallet vault tag was a lossy char-substitution
  (two distinct files could map to one vault). Append an 8-hex FNV-1a of the raw
  filename so distinct wallets never share a vault. +unit test.
- LOW seed-adopt: removeVault() on adopt so the legacy wallet's PIN passphrase
  isn't left associated with the new seed wallet (same file name).
- LOW: clear lock_unlock_in_progress_ on switch too.

Deferred (documented): the 1.5s start grace can't catch a wallet that fails LATE
in daemon init (the existing crash-wedge detection still applies); beginShutdown's
join of the switch task can briefly freeze the UI during quit (necessary to avoid
orphaning the daemon).

DanSandClaude Opus 4.8 fc509a9340 fix(wallet-switch): cluster B — daemon-switch robustness
From the wallet-switching audit:

- Revert on failure (HIGH): switchToWallet persisted active_wallet_file before
  confirming the new daemon started, so a missing/corrupt wallet wedged across
  restarts. The switch worker now confirms dragonxd survives a grace period; on
  failure it flags the main thread (processWalletSwitchRevert), which restores
  the previous wallet file + re-scopes the vault + re-arms reconnect (settings
  writes stay on the main thread).
- Cross-guard concurrent lifecycle ops (HIGH): switchToWallet now refuses during
  a rescan/repair (state_.sync.rescanning) or seed migration; rescan/repair now
  refuse while daemon_restarting_; and restartDaemonAfterEncryption now sets
  daemon_restarting_ (which also fixes a latent reconnect-to-a-stopped-daemon
  race during the encryption restart). So the switch/adopt/restart/rescan/repair/
  encryption ops are mutually exclusive.
- Quit during switch (MED): beginShutdown now joins the "Switch wallet" task (like
  the adopt task) so quitting can't orphan a freshly-started dragonxd.
- Reset the daemon crash count on switch (LOW) so a prior crash-wedge can't block
  reconnecting to the new wallet.

DanSandClaude Opus 4.8 f546d3e2b1 fix(wallet-switch): cluster A — identity/secret teardown on wallet switch
From the wallet-switching audit (HIGH-severity cross-wallet leaks):

- Chat identity leak: the full-node switch (switchToWallet) and seed-migration
  adopt reset state_ but NOT the HushChat identity, so wallet A's decrypted
  conversations surfaced under wallet B and outgoing chat was signed with A's
  keypair. Factor the existing teardown into App::resetChatSession() and call it
  on both wallet-change paths (the lite path already reset it via
  rebuildLiteWallet, which now uses the helper too).
- Global PIN vault: the PIN quick-unlock vault was a single vault.dat, so after
  a switch wallet A's stored passphrase was offered/applied to encrypted wallet
  B. SecureVault is now scoped per wallet (vault-<walletfile>.dat); the default
  wallet keeps the legacy vault.dat for back-compat. vault_ is constructed for
  the active wallet and re-scoped on switch, so B has its own (empty) vault.
- Lock-screen state: switching now clears the carried-over failed-attempt
  counter + lockout timer and secure-zeroes the passphrase/PIN entry buffers so
  the previous wallet's unlock state can't apply to the new one.

DanSandClaude Opus 4.8 8a30578872 feat(settings): migrate Export Private Key modal + fix outside-click secret leak
Phase 2 (first security modal), presentation-only + the review's one finding.

Migration: struct-form BlurFloat overlay (was legacy positional); full i18n
(reusing export_private_key / key_export_private_warning / key_export_private_key /
select_address / key_export_fetching / export / copy / close, plus one new
key_export_failed); DialogWarningHeader; centered DialogActionFooter (Export +
Close) + a Copy TactileButton; async UX (export_in_progress_ spinner, export_error_
line). The exported key stays in the char[256] buffer shown via a read-only
InputTextMultiline (deliberately NOT AddressCopyField, which would copy the secret
into a lingering std::string). exportPrivateKey is untouched.

Security fix (found by the adversarial review): the 0a "outside-click/Esc wipe" via
the Begin-returns-false early-return was UNREACHABLE — BeginOverlayDialog clears
show_export_key_ mid-frame but still returns true, so an outside-click/Esc dismiss
left the exported spending key un-wiped in export_result_. Add the in-body
`if (!show_export_key_)` teardown before EndOverlayDialog (the proven import-dialog
pattern), which is the real wipe point for every dismiss path.

DanSandClaude Opus 4.8 2b191cea34 fix(settings): securely wipe the exported private key (no heap-lingering secret)
The Export Private Key dialog held the exported spending key in a plain
std::string cleared only with .clear() — never sodium_memzero'd — and on
outside-click/Esc the overlay's early return skipped even that, so the secret
lingered in freed heap. Hold it in a fixed char[256] and sodium_memzero on every
close path (Close button, outside-click/Esc early return, address change). Guard
the async export callback so it can't populate the buffer after the dialog closed.

Standalone security fix ahead of the settings-modal redesign (Phase 0a); the
dialog's full restyle is Phase 2.

DanSandClaude Opus 4.8 828018de2b feat(settings): sweep a private key's funds to your own wallet
Add a "Sweep to my wallet (don't keep the key)" option to the Import Private
Key dialog (spending keys only). Rather than keeping the key, it imports the
key, then sends ALL its funds to a destination you control — a freshly
generated shielded address by default, or an existing wallet address you pick.

Flow (App::sweepPrivateKey): import the key (rescan; the stock node has no
address index, so its UTXOs/notes can't be enumerated otherwise) → confirm it
holds spendable funds → resolve the destination → z_sendmany balance-minus-fee
from the key's address to the destination, via the existing tested submitZSendMany
wrapper + async-operation tracker. The imported key is left in the wallet with an
empty balance (there is no remove-key RPC) — stated plainly in the UI caveat.

Design notes forced by this daemon (verified against external/dragonx):
- z_importkey returns null here, so the shielded source address is found by
  diffing z_listaddresses before/after import (aborts if the pre-snapshot fails,
  so a wrong address can never be picked). Transparent uses importprivkey's return.
- z_sendmany, NOT z_mergetoaddress: moves a single-UTXO transparent source (the
  common paper-wallet case) and fails loudly instead of silently leaving a
  remainder. Amount computed in integer satoshis for an exact fixed-decimal string.
- Clear errors for no-funds / unconfirmed / dust-below-fee / already-imported.
- The mode + destination are locked during a running sweep; a sweep that finishes
  while the dialog is closed still shows its Done/Error+txid on reopen; sweep UI
  can't bleed into the watch-only viewing dialog.

i18n: 8 new sweep_* keys (en + 8 langs); dynamic status strings are English,
matching the beginSweepToSeedWallet precedent.

Reviewed across three adversarial multi-agent rounds (fund-safety focus): round 1
caught the feature was broken for shielded keys (z_importkey null) and rejected
single-UTXO transparent sources; round 2 caught reopen/double-submit/precision
issues; round 3 verified the fixes. NOT yet exercised against a live daemon —
needs a small-amount mainnet test before it's trusted, like migrate-to-seed.

DanSandClaude Opus 4.8 1fc3e03e6f feat(settings): rename to "Import Private Key" + add scan height to it
Follow-up to the key/viewing-key button split:

- Rename the "Import Key…" button to "Import Private Key…" (settings_import_key
  value in en + all 8 langs, reusing the existing import_key_title wording) so it
  reads as the natural counterpart to "Import Viewing Key…". The dialog title was
  already "Import Private Key". The viewing-key wrong-type redirect hint now names
  the renamed button.

- Show the "scan from block height" field in the private-key (spending) dialog too,
  not just the viewing-key one. z_importkey accepts a start height, so a shielded
  spend import of a recent key needn't rescan the whole chain. Transparent WIF
  (importprivkey) has no such param, so once a transparent key is recognized the
  field is disabled, its buffer cleared, and a "Transparent keys always rescan
  fully" note replaces the hint. importPrivateKey already gates the start-height
  append on (viewing || shielded), so transparent imports never receive it.

- i18n: shared scan keys renamed import_viewkey_scan_{label,hint} ->
  import_scan_{label,hint}; added import_scan_transparent (en + 8 langs).

Reviewed via an adversarial multi-agent pass (rpc-routing / i18n / ui-logic /
consistency); only two nits surfaced (stale disabled-field value + a stale
comment), both fixed here.

DanSandClaude Opus 4.8 f428292ea4 feat(settings): split import into separate key + viewing-key buttons
Backup & Data now has two distinct import actions instead of one
auto-detecting dialog:

- "Import Key" imports a spending key (transparent WIF or shielded
  z-spending key) with the strong "grants access to funds" warning.
- "Import Viewing Key" imports a watch-only shielded viewing key
  (zxviews…) with a milder eye/watch-only note and an optional
  "scan from block height" field — z_importviewingkey accepts a start
  height, so watching a recent address needn't rescan the whole chain.

The shared Material dialog (renderImportKeyDialog) branches on
import_view_mode_: title, warning tone, field label, the live type
indicator, and the recognition guard. A key valid for the *other*
button (e.g. a spending key pasted into the viewing-key dialog) now
shows a redirect hint rather than a generic "unrecognized" error.

importPrivateKey gains a startHeight arg, appended to the shielded
import RPCs (z_importviewingkey / z_importkey) and ignored for
transparent WIF (importprivkey has no start-height param). The
scan-height buffer is wiped on open/close alongside the key buffer.

i18n: 9 new keys (button label + tooltip, viewing title/note/field,
scan label/hint, two wrong-type redirect hints) with translations for
all 8 languages; CJK subset rebuilt (+1 glyph). A modal-import-viewkey
sweep surface is added for the viewing-mode dialog.

DanSandClaude Opus 4.8 46f3001360 feat(settings): redesign the Import Key dialog
Rework the full-node Import Key dialog into a safer, Material-consistent, more
capable flow:

- Security: the key is masked by default (Password) with a reveal (eye) toggle,
  a DialogWarningHeader "only import a key you own" note, and the buffer is
  wiped with sodium_memzero on close and on successful import.
- Progress: import triggers a blocking full-chain rescan; the dialog now shows
  "Importing & rescanning — this can take several minutes" with LoadingDots and
  disables Import while it runs (no double-submit). Offline shows a "connect a
  running node" note and disables Import up front.
- Viewing keys: the classifier gains isViewingKey / isRecognizedImportKey;
  importPrivateKey auto-detects a shielded viewing key (zxviews…) and routes to
  z_importviewingkey (watch-only) vs z_importkey / importprivkey. The live type
  indicator shows Transparent / Shielded spending / Shielded viewing (watch-only).
- Result: on success the imported address is captured from the RPC result and
  shown via AddressCopyField.
- Material restyle (OverlayDialogSpec/BlurFloat + TactileButton + Esc) and full
  i18n (12 new keys x 8 languages; CJK subset rebuilt).

Verified: rendered on dark + light skins; a seeded zxviews… key shows the masked
field + "Shielded viewing key (watch-only)" indicator.

DanSandClaude Opus 4.8 82da4af857 feat(market): per-pair candle cache — instant switch-back, no re-fetch
The per-exchange chart used a single buffer keyed by the loaded pair, so
bouncing between venues (Ourbit <-> NonKYC) re-fetched every switch (loading
spinner each time). Add a per-pair cache: each venue's fetched candles (OHLC +
derived close series) are kept keyed by "<identifier>:<BASE>/<QUOTE>". Switching
back to a recently-viewed pair loads from the cache instantly — no fetch, no
spinner — while entries older than 30 min re-fetch to stay fresh. Bounded to 16
entries (irrelevant for DRGX's 2 venues, but safe if it lists more). Cache is
main-thread-only (populated by the worker's completion MainCb), so no races.
