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.

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.

XmrigUpdater and DaemonUpdater carried byte-identical libcurl code —
httpGet, downloadToFile, and the write/progress callbacks — including the
security-critical TLS-verify (SSL_VERIFYPEER=1 / SSL_VERIFYHOST=2) and
max-body-size options, duplicated across two signature-verified
download-and-execute files that had to be hand-kept in sync.
Hoist that machinery into src/util/http_download.{h,cpp}:
- util::httpGetString(url, logTag)
- util::httpDownloadToFile(url, dest, logTag, maxBytes, onProgress)
threading progress + cancellation through a std::function (returning false
aborts the transfer) instead of the class `this` pointer. Each updater's
httpGet/downloadToFile become one-line forwarders that bind their own log
tag and archive-size cap (64 MiB miner / 256 MiB node, both preserved).
Every curl option is preserved byte-identically (verified by diffing the
setopt lines against the pre-change code — the only deltas are the
now-parameterized MAXFILESIZE cap and the XFERINFODATA payload). No behavior
change; the TLS/size-guard options now live in exactly one place.
Deliberately scoped DOWN per the audit's own guidance: the divergent
per-updater logic (release DTOs/parsers, checksum-table parsing, version
compare, and installResolved's per-member-SHA vs transitive-trust verify,
install strategy, and chmod scope) stays in each class — NOT merged behind a
base-class/virtual-hook layer, which would raise review cost on
signature-verified execute-code and risk a subtle security regression. The
shared-DTO/parser consolidation (~77 test refs of churn on stable code) is
left as a separate, lower-value follow-up.
Full-node + Lite build clean; ctest 1/1; source-hygiene clean.

Add a full-node daemon updater (util/DaemonUpdater + daemon_download_dialog)
reachable from Settings -> NODE & SECURITY: downloads/verifies (SHA-256 +
enforced ed25519 signature) and atomically installs the latest dragonxd from
the project Gitea, with a "Restart daemon now" step. Add a shared "Browse all
releases..." picker (release_list_view) to both the miner and daemon updaters
so users can pin older/pre-release builds. Pure no-I/O cores
(daemon_updater_core / xmrig_updater_core) are unit-tested; sign-daemon-release.sh
signs release archives offline.
