Six behavior-preserving consolidations from the audit:
- RPCClient::call() overloads share a private performCall() (payload dump +
curl_easy_perform + http code) and a static parseRpcResult() (error->RpcError
extraction). The timeout overload restores the prior timeout in both the
success and catch paths, exactly as before.
- The six UnifiedCallback methods delegate to one splitUnified() that builds
the (Callback, ErrorCallback) pair once (null-check preserved).
- One liteTrimCopy() in lite_connection_service replaces 5 file-local
trim-copy helpers across the lite slice.
- lite_wallet_controller's inline height JSON parse now routes through the
tested parseLiteHeightResponse().
- theme_effects.cpp: unpackRGB()/scaledAlpha() replace 14 RGB-unpack + 5
alpha-scale copy-paste blocks.
- settings.cpp load() uses loadScalar()/loadClamped() helpers for ~44 scalar
fields. Besides removing boilerplate this HARDENS loading: ~44 fields that
previously only checked contains() now also verify the JSON type, so a
malformed value in settings.json falls back to the default instead of
throwing/misreading. Custom cases (enum parses, legacy migrations, arrays)
stay inline; save() is unchanged.
Full-node + Lite build clean; ctest 1/1; hygiene clean.

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.

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.
