settings.json and addressbook.json were written in place with a bare ofstream —
a crash or power loss mid-write truncated the file, and on the next launch the
parse failure silently reset every preference (hidden/favorite addresses, labels,
pool workers, language, theme, lite-server list) because the next save overwrote
the corrupt file with defaults.
Add Platform::writeFileAtomically() (temp file -> fsync -> atomic rename; dir
fsync on POSIX, MoveFileEx on Windows; optional owner-only 0600) and route both
saves through it. On a parse failure, quarantine the unreadable settings file to
settings.json.corrupt-<ts> instead of clobbering it.

A lite-wallet-only "Network" tab (full-node keeps the Peers tab; exactly one shows per variant)
to manage lightwalletd servers, replacing the basic selector that was in Settings.
- Card list of servers with per-server latency + status dot, DNS host + resolved IP, and an
Official/Custom pill. Official DragonX servers get a glowing outline.
- Pick a server (Sticky) by clicking its card, or toggle "use a random server" (Random mode);
selection applies immediately (App::rebuildLiteWallet(force=true) tears down + rebuilds the
controller against the new server and resyncs — its dtor detaches the uninterruptible sync
thread, so this doesn't block).
- Add custom servers; hide/unhide servers (persisted set, revealed by a "Show hidden" toggle).
- Latency/IP come from a new background probe (util/LiteServerProbe): libcurl CONNECT_ONLY does
the TCP+TLS handshake (works for gRPC lightwalletd, no HTTP response needed), recording
APPCONNECT_TIME as latency and CURLINFO_PRIMARY_IP. Auto-runs on tab open + a Refresh button.
Wiring: WalletUiSurface::LiteNetwork (gated !fullNodePagesAvailable) + NavPage::LiteNetwork in
the sidebar + app.cpp dispatch; settings gains a hidden-servers set; isOfficialLiteServer() added
to lite_connection_service. The Settings page lite-server selector + its plumbing are removed
(single source of truth = the tab).
Reuses the existing server model (LiteServerPreference, Sticky/Random, selectLiteServer) and UI
primitives (DrawGlassPanel, ThemeEffects glow, peers-tab ping-dot idiom). Unit-tested
(liteServerHost, isOfficialLiteServer) + an env-gated live probe (verified vs lite.dragonx.is:
online, latency, IP). Both variants + lite-backend build; suite passes; hygiene clean; GUI
smoke-launched without crash.

Wires util::XmrigUpdater into the GUI:
- ui/windows/xmrig_download_dialog.h: a modal (mirrors BootstrapDownloadDialog) that drives
the updater — Checking -> Up-to-date/Update-available -> Downloading/Verifying/Extracting ->
Done/Failed, with a progress bar and a "verified against its published checksum" note. On
success it persists the installed release tag to settings. Rendered each frame from App::render.
- mining_tab: an "Update miner…" button in the pool section, disabled (with a tooltip) while
xmrig is running so a live binary is never replaced.
- settings: persist the installed DRG-XMRig tag (xmrig_version) for update detection.
Both variants build; suite passes; GUI smoke-launched without crashing.

Adds a fail-open, local-only gate that decides whether the lite wallet may run,
so a post-release issue can disable it and rollout can be staged — without any
phone-home (privacy posture: no runtime network fetch; the per-install rollout
bucket is a hashed, never-transmitted local id).
- wallet/lite_rollout_policy.{h,cpp}: a pure decision core. Order — emergency env
kill-switch (absolute) -> local override -> manifest gates (global enable /
version floor-ceiling / blocklist / staged-rollout permille) -> fail-open allow.
Plus a JSON manifest loader (missing/invalid -> fail-open) and FNV-1a bucketing.
- Threads the decision through LiteWalletController -> LiteWalletLifecycleService:
new availability() reason RolloutDisabled blocks create/open/restore and surfaces
the gate's user-facing message via the lifecycle status.
- App::rebuildLiteWallet() resolves it from: DRAGONX_LITE_KILL_SWITCH (env), the
lite_rollout setting (auto/force_on/force_off), and a locally-cached manifest at
<config-dir>/lite_rollout.json. install id generated once via libsodium.
- Settings: persist lite_rollout override + the install id.
A signed remote fetcher can populate the manifest cache later without touching the
policy. Unit-tested (version compare, bucketing, override/env precedence, manifest
gates, staged rollout, loader fail-open, controller integration) and runtime-verified
on Linux (env kill-switch, manifest disable, control sync). Both variants build;
full suite passes; hygiene clean.

Add an encrypted SQLite transaction history cache with cached tip metadata and
per-address shielded scan progress so startup and full refreshes avoid
re-scanning every z-address while still invalidating on wallet/address/rescan
changes.
Improve wallet history loading by paging transparent transactions, preserving
cached shielded and sent rows, keeping recent/unconfirmed activity visible, and
classifying mining-address receives. Show z_sendmany opid sends immediately in
History and Overview, pin pending rows through refreshes, and apply optimistic
address/balance debits until opids resolve.
Add timestamped RPC console tracing by source/method without logging params or
results, reduce redundant refresh/RPC calls, and cache Explorer recent block
summaries in SQLite.
Expand focused tests for transaction cache encryption, scan-progress
persistence/invalidation, history preservation, operation-status parsing,
pending send visibility, and Explorer/RPC refresh behavior.

treats system as active; toggle in mining tab header (default: on)
Supports AMD sysfs, NVIDIA nvidia-smi, Intel freq ratio; -1 on macOS

thread count instead of xmrig API threads_active which lags on restart
- Apply active thread count on initial mining start when user is active
- Skip idle mining adjustments while benchmark is running

- link iphlpapi on Windows for GetExtendedTcpTable
Security & encryption:
- update local encryption state immediately after encryptwallet RPC
so Settings reflects the change before daemon restarts
