The node kept falling behind the network near the tip because sync
DETECTION was starved: getblockchaininfo was queued behind the
O(mapWallet) wallet RPCs (z_gettotalbalance / z_listunspent), so
longestchain went stale, the wallet decided it was "synced", and it
resumed hammering cs_main — a feedback loop.
- Issue getblockchaininfo FIRST each cycle and skip the balance/address/
tx refresh entirely while behind, so sync state (and kSyncProfile)
updates before any heavy wallet scan runs.
- Gate the two chat note scans (refreshChatNoteBudgetNode /
fastScanChatMemos) on effectivelySyncing() and the active page, so chat
memo scanning no longer competes with block connection during sync.
- Windows debug.log tailer: reset the read offset when dragonxd truncates
the log on startup (it was stranding at Block:0 with no witness/rescan
progress).
- Tests cover the getblockchaininfo-first ordering and behind-skip.

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.

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.

Sending a small amount from an address holding a large balance made the displayed
balance collapse to ~0 until the tx confirmed. A shielded spend consumes the whole
source note; the change returns as a 0-confirmation note, and every balance query
used the default minconf=1 — so the spent note dropped out and the change wasn't
counted yet.
Split every balance into two views:
- DISPLAY (balance / privateBalance / transparentBalance / totalBalance) — now
queried at minconf=0, so it INCLUDES the user's own pending change and no longer
craters. This is what the Overview, balance tab, market portfolio and receive
tab show. unconfirmedBalance is now populated (= total - spendable).
- SPENDABLE (new spendableBalance / spendable*Balance) — confirmed (minconf>=1),
what z_sendmany (run at minconf=1) can actually spend. The Send form's available/
Max/validation, the from-address selection, the drag-to-transfer dialog cap, the
chat pay-from and the auto-shield gate all size off these, so they never offer
0-conf change the daemon would reject.
Implementation: a single z_listunspent(0)/listunspent(0), partitioned per-note by
"confirmations">=1; z_gettotalbalance called at minconf 0 (display) and 1
(spendable); the z_getbalance fallback queries both. applyPendingSendDelta (the
optimistic post-send debit) now touches ONLY the spendable fields — debiting the
display too would re-crater it on top of the honest minconf=0 RPC. Lite mirrors
spendableBalance = balance (its per-address balance is already confirmed) so lite
sends aren't zeroed. The confirmed-only gates (seed-migration/sweep z_gettotalbalance,
sweep z_getbalance(addr,1), z_sendmany's minconf arg) are untouched.

Portfolio-group sparklines previously resampled the ~24-minute in-session price
buffer, so the hour/day/week/month intervals could never fill. Fetch real
historical USD series from CoinGecko /market_chart and back each interval with
appropriately-grained data.
- MarketInfo gains two timestamped series: price_chart_intraday (days=1, 5-min)
and price_chart_daily (days=365, daily), plus a fetch timestamp.
- App::refreshMarketChart() fetches both on the RPC worker via the TLS-verifying
util::httpGetString helper, self-throttled to ~30 min (historical data moves
slowly). Gated by getFetchPrices(); triggered on connect and each price tick.
- Pure NetworkRefreshService::parseCoinGeckoMarketChart() parses {"prices":
[[ms,price],...]} into (unix-seconds, price); malformed rows skipped. Unit-tested.
- market_tab pfSparklineSeries() maps interval -> series+bucket: minute = live
buffer; hour = intraday bucketed to 1h; day/week/month = daily bucketed to
1d/7d/30d. Falls back to the in-session buffer until the fetch populates.

Three P1 structural refactors from the audit; no behavior change.
1. Extract the ~180-line daemon-stdout rescan/witness parser out of the
~790-line App::update() into a pure, static, unit-testable
NetworkRefreshService::parseDaemonRescanOutput() returning a
DaemonRescanScan result struct (sits next to the existing static parse*
siblings). The scanning half moved verbatim; App::update() keeps the
state-application half, now reading scan.* fields. Adds
testParseDaemonRescanOutput() covering all six daemon signals + edge
cases against fixture log snippets — previously untestable without a
live daemon.
2. Extract the ~95-line global keyboard-shortcut block (Ctrl+, / theme
cycle / F5 / low-spec / effects / gradient / wizard) out of
App::update() into App::handleGlobalShortcuts().
3. Collapse the ImGuiAcrylic frontend fork: the GLAD and DX11 namespaces
were ~375 lines of semantically-identical code (the frontend makes zero
direct GL/DX calls — all backend work delegates to AcrylicMaterial, which
has a backend per API). Extended the single frontend's guard to
#if defined(DRAGONX_HAS_GLAD) || defined(DRAGONX_USE_DX11) and deleted the
DX11 duplicate, leaving the no-backend stub. Kills the Windows/DX11 drift
hazard (acrylic frontend changes now made once).
Verified: full-node + Lite build clean; ctest 1/1 (incl. the new parser
tests); source-hygiene clean; and the collapsed acrylic path was
compile-verified under DX11 via the mingw-w64 Windows cross-build
(ObsidianDragon.exe links).

The full-node wallet polled the daemon at the per-tab cadence regardless of sync state.
On the Peers/Network tab that meant getpeerinfo every 5s + core every 5s + a full
transaction scan on every new block — and blocks arrive fast during sync. Each of those
calls takes the daemon's cs_main lock, the same lock block connection needs, so the node
synced noticeably slower than on the lightweight Console tab (core 10s, no peer polling).
Make the refresh cadence sync-aware:
- RefreshScheduler::kSyncProfile {core 10s, transactions/addresses/peers disabled} is applied
to ALL tabs while state_.sync.syncing, and reverts to the per-tab profile when sync ends.
applyRefreshPolicy() picks the profile; update() re-applies it on the syncing<->synced
transition. This suppresses getpeerinfo and the per-block tx scan during sync (that data is
incomplete mid-sync anyway) — every tab now syncs as fast as Console.
- collectCoreRefreshResult(rpc, includeBalance): skip z_gettotalbalance (wallet lock + cs_main)
while syncing; only getblockchaininfo runs, which is also what drives sync-progress detection.
applyCoreRefreshResult already leaves the balance untouched when balanceOk is false.

Two issues shared one root cause: the shielded-receive scan marked each z-address "scanned
at the EXACT current tip," but a new block (~36s on DRGX) advances the tip and invalidates
every prior per-address scan. A wallet with more z-addresses than one refresh cycle can
scan therefore never reached "all scanned at tip" — so shieldedScanComplete stayed false
and transactions_dirty_ stayed true forever, which (a) kept the history-refresh banner lit
and the full rescan churning every cycle, and (b) blocked maybeFinishTransactionSendProgress
(it waited on transactions_dirty_), leaving the send-progress indicator stuck on.
Fix 1 — completion tolerance. Add TransactionRefreshSnapshot::shieldedScanTipTolerance: an
address counts as fresh if its last scan is within N blocks of the tip (0 = old strict
behavior, so existing tests are unchanged). The app scales N with the z-address count
(2 + count/96, capped at 50), so a multi-block pass can COMPLETE before its earliest scan
goes stale. This also throttles full rescans to ~N blocks instead of every block —
transactions_dirty_ clears, the banner stops, and CPU/RPC churn drops. Already-fresh
addresses are skipped, so the per-block cost falls back to just the (cheap) transparent
listtransactions.
Fix 2 — send-progress gate. maybeFinishTransactionSendProgress() no longer waits on the
transaction history scan (transactions_dirty_ / Transactions job): the sent tx is already
shown via the optimistic pending insert, and the spend is reflected once the balance
refresh lands, so it now finishes on the address/balance signal alone.
Test: a tolerant snapshot skips recently-scanned addresses (shieldedAddressesScanned == 0,
shieldedScanComplete) while a strict one re-scans them.

z_sendmany returns an opid immediately; the tx is built/signed/broadcast
asynchronously afterward. The send path showed "Transaction sent successfully!"
and cleared the form on opid receipt, so a later async failure contradicted it.
Shield/merge stored the opid only in a dialog-local static (never polled), and
auto-shield ran a blocking z_shieldcoinbase on the UI thread and discarded its
opid — async failures of all three were silently lost.
- Add App::trackOperation(opid) so shield/merge/auto-shield register with the
shared opid poller (failures surface, balances refresh on completion).
- Defer the full-node send's success/failure to the poller via per-opid callbacks
(parseOperationStatusPoll now exposes failureByOpid); the "Sending..." spinner
covers the finalizing window, and the form is kept until terminal status.
- Dispatch auto-shield through the worker thread and use the configured fee.

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.

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.
Replay cached outgoing viewtransaction entries during transaction refresh so shielded sends created from the wallet remain in the History tab after send tracking is cleared.
Keep incomplete tracked sends retryable, preserve cached send timestamp/confirmation metadata, and emit a send placeholder from gettransaction metadata when viewtransaction enrichment is not yet available.
Add regression coverage for cached sends, retryable empty entries, placeholder sends, and send txid cleanup behavior.
