Both variants hardcoded "ObsidianDragon" as the per-user config folder
(settings.json, themes, the lite_rollout cache), so the lite app and the
full-node app shared one settings.json. That cross-variant pollution can leave
the lite server selection in a bad state — and since openWallet() contacts the
selected lightwalletd server, a wrong/empty server URL there makes an existing
wallet fail to open (a silent "disconnected" spinner).
Use DRAGONX_APP_NAME (already "ObsidianDragon" / "ObsidianDragonLite" per variant)
for the config-dir name in Settings::getDefaultPath, Platform::getConfigDir and
getObsidianDragonDir (and the theme-setup exe-name probe). Full-node is unchanged;
lite now reads/writes %APPDATA%\ObsidianDragonLite (and ~/.config/ObsidianDragonLite),
so it starts from a clean, isolated config and uses default servers.
Note: the lite wallet file itself lives in the litelib backend's own data dir
(unaffected); this isolates the GUI config only.

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.

The full-node app and ObsidianDragonLite are now versioned separately:
- project() VERSION -> 1.3.0 (suffix cleared); DRAGONX_LITE_VERSION -> 1.0.0.
- A DRAGONX_APP_VERSION* set (resolved per variant in the lite/full block) feeds the generated
header (version.h.in), the Windows VERSIONINFO/.rc + manifest, and the build summary — so each
variant reports its own version. The .rc/manifest name fields also follow DRAGONX_APP_NAME so a
lite .exe's properties read "ObsidianDragonLite".
- build.sh resolves the release-filename version per variant by parsing CMakeLists (single source
of truth) instead of a hardcoded string.
Also fixes a latent variant-bleed: build.sh now passes DRAGONX_BUILD_LITE and
DRAGONX_ENABLE_LITE_BACKEND explicitly (ON *and* OFF), so switching variants in a shared build dir
can't reuse a stale cached value (a prior --lite build was making a subsequent full-node build
produce the lite name/version).
Both variants build + report the right version (full 1.3.0, lite 1.0.0); suite passes.

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.

Preserve the previously-uncommitted lite wallet implementation and related dev WIP
under version control:
- src/wallet/ lite services: client bridge, bridge runtime, connection, lifecycle,
sync, gateway, result parsers, state mapper, artifact contract/resolver, refresh
services, UI adapters, wallet_backend/capabilities. (Includes two small M1 fixes:
lifecycle walletReady now parses the response; default chain name -> "main".)
- src/chat/ chat protocol; tests/fixtures/ (lite + hushchat); tools/hushchat_fixture_check.cpp;
scripts/build-lite-backend-artifact.sh.
- Pre-existing modified app_network/security/wizard, network_refresh_service, sidebar,
mining_tab, bootstrap dialog, and version headers captured as-is.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add --lite build flow and ObsidianDragonLite target naming, hide full-node pages/features in lite mode, enforce pool-only mining in lite, and include chat port feasibility audit documentation.
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.
s_dropTargetIdx was reset to -1 unconditionally each frame, including
the release frame. Since drop target detection runs in PASS 2 (after
the drop handler), the target was always -1 when checked. Only reset
while mouse button is held so the previous frame's value is preserved.
Also bump version to 1.2.0-rc1 and add release notes.
- Rewrite RenderSharedAddressList with two-pass layout architecture
- Add drag-to-transfer: drag address onto another to open transfer dialog
- Add AddressLabelDialog with custom label text and 20-icon picker
- Add AddressTransferDialog with amount input, fee, and balance preview
- Add AddressMeta persistence (label, icon, sortOrder) in settings.json

- Keyboard nav (Up/Down/J/K, Enter to copy, F2 to edit label)
- Add i18n keys for all new UI strings
- Replace hardcoded IP addnodes with node.dragonx.is, node1–4.dragonx.is
in both daemon launch params and auto-generated DRAGONX.conf
- Add max_connections setting (persisted, default 0 = daemon default);
passed as -maxconnections= flag to dragonxd on startup
- Show blocks/sec in status bar during sync with exponential smoothing
(e.g. "Syncing 45.2% (12340 left, 85 blk/s)")
Security (P0):
- Fix sidebar remaining interactive behind lock screen
- Extend auto-lock idle detection to include active widget interactions
- Distinguish missing PIN vault from wrong PIN; auto-switch to passphrase
Blocking UX (P1):
- Add 15s timeout for encryption state check to prevent indefinite loading
- Show restart reason in loading overlay after wallet encryption
- Add Force Quit button on shutdown screen after 10s
- Warn user if embedded daemon fails to start during wizard completion
Polish (P2):
- Use configured explorer URL in Receive tab instead of hardcoded URL
- Increase request memo buffer from 256 to 512 bytes to match Send tab
- Extend notification duration to 5s for critical operations (tx sent,
wallet encrypted, key import, backup, export)
- Add Reduce Motion accessibility setting (disables page fade + balance lerp)
- Show estimated remaining time during mining thread benchmark
- Add staleness indicator to market price data (warning after 5 min)
New i18n keys: incorrect_pin, incorrect_passphrase, pin_not_set,
restarting_after_encryption, force_quit, reduce_motion, tt_reduce_motion,
ago, wizard_daemon_start_failed
Split monolithic refreshData() into independent sub-functions
(refreshCoreData, refreshAddressData, refreshTransactionData,
refreshEncryptionState) each with its own timer and atomic guard.
Per-category timers replace the single 5s refresh_timer_:
- core_timer_: balance + blockchain info (5s default)
- transaction_timer_: tx list + enrichment (10s default)
- address_timer_: z/t address lists (15s default)
- peer_timer_: encryption state (10s default)
Tab-switching via setCurrentPage() adjusts active intervals so
the current tab's data refreshes faster (e.g. 3s core on Overview,
5s transactions on History) while background categories slow down.
Use fast_worker_ for core data on Overview tab to avoid blocking
behind the main refresh batch.
Bump version to 1.1.2.

- Restructure RenderMiningTab with wrapper pattern for exception safety
- Fix default pool URL to include port (pool.dragonx.is:3433)
DRAGONX_DEBUG was defined unconditionally, causing D3D11CreateDevice() to
request the debug layer via D3D11_CREATE_DEVICE_DEBUG. This layer is only
available on machines with the Windows SDK or Graphics Tools installed,
so the call fails with DXGI_ERROR_SDK_COMPONENT_MISSING on regular user
machines — causing the app to silently exit.
Mine-when-idle:
- Auto-start/stop mining based on system idle time detection

- persist verbose_logging preference in settings.json
- link iphlpapi on Windows for GetExtendedTcpTable
Security & encryption:
- update local encryption state immediately after encryptwallet RPC
so Settings reflects the change before daemon restarts
- show notifications for encrypt success/failure and PIN skip
- use dedicated RPC client for z_importwallet during decrypt flow
to avoid blocking main rpc_ curl_mutex (which starved peer/tx refresh)
- force full state refresh (addresses, transactions, peers) after
successful wallet import
Network tab:
- redesign peers refresh button as glass-panel with icon + label,
matching the mining button style
- add spinning arc animation while peer data is loading
(peer_refresh_in_progress_ atomic flag set/cleared in refreshPeerInfo)
