DanSandClaude Opus 4.8 3f82af99c4 refactor(market): resolve exchange/pair selection through one helper
The chart fetch and the Market tab both resolved the saved exchange and
pair names into the registry, with their own near-identical scans and
slightly different fallbacks. Keeping two copies risked the chart and
the chips disagreeing about which pair was selected.

- A single resolver maps the saved names to a registry index, matching
  the exchange name (any exchange when none is saved) then the pair
  display name, and falling back to the registry's first pair, the UI
  default. The chart fetch and the Market tab both call it.
- The Market tab now derives its selection indices from the saved names
  against the current registry every frame, so the indices stay correct
  when the live exchange list replaces the fallback; a steady-state fast
  path skips the scan once the indices already name the saved selection.

Tests: the resolver returns the right index for a matched exchange/pair,
an empty-exchange match, and the first-pair fallback on misses.

DanSandClaude Opus 4.8 ce00621a4a perf(market): precompute the address-picker selection flag once
The portfolio address picker's sort comparator looked up each address in
the selected-address set on every comparison, two hash lookups per call,
and the per-row draw repeated the lookup again. On a long address list
that is a lot of redundant hashing every frame.

- Each filtered candidate now carries its selected flag, looked up once
  when the list is built. The comparator reads the stored flag, so the
  sort produces the same ordering with no lookups of its own.

DanSandClaude Opus 4.8 a631e4421a refactor(contacts): share case-insensitive compare, truncation helpers
The contacts list carried its own lowercase-and-compare sort, its own
lowercase substring search, and an inline linear middle-truncation loop
for fitting an address to a column width. These duplicated logic that
belongs in the shared text helpers.

- A new allocation-free case-insensitive compare replaces the per-sort
  lowercasing; it lowercases ASCII per byte and leaves bytes >= 0x80
  alone, so UTF-8 labels sort exactly as before.
- Search now uses the shared case-insensitive contains helper.
- Middle-truncation to a pixel width moves to a shared template that
  binary-searches the fit (about log2(n) width measurements instead of
  up to n) while producing the same result as the old linear shrink.

Tests: the compare matches lowercase-then-compare across ASCII, UTF-8
bytes and length ties, and the fit helper matches the old linear loop
across lengths and widths.

DanSandClaude Opus 4.8 32ea4d0524 fix(mining): keep the thread benchmark running while the tab is hidden
The thread benchmark state machine was advanced from the Mining tab's
render path, so it only progressed while that tab was visible and the
window was on screen. Hiding the tab or minimizing the window froze the
benchmark mid-sweep.

- The benchmark now advances from the main update loop, ungated by
  connectivity, so it keeps running when the tab is hidden or the window
  is minimized.
- Its clock is driven from a steady wall-clock reading rather than the
  render delta, and each step is clamped like the other logic timers so
  a suspend/resume cannot leap a benchmark phase.

DanSandClaude Opus 4.8 fae5ef05b9 fix(mining): restore the miner after a benchmark only if it was running
Cancelling a thread benchmark always stopped and restarted the pool
miner at its pre-benchmark thread count, even when the user had not been
mining before the benchmark began. That silently started the miner on a
plain cancel or a switch to solo mode.

- A cancel now always drops the candidate-thread miner, and restarts the
  pool miner only when the user was mining before the benchmark, read
  from a snapshot taken at the start rather than the live running state
  (the benchmark sweep transiently stops the miner between candidates,
  so a live check would drop the restore).
- Callers that must not restore the miner (leaving solo mode) pass the
  new restore flag as false.

DanSandClaude Opus 4.8 c5b325a752 perf(charts): fill chart areas in one linear pass
The filled sparklines and the market price chart built their area fill
with PathFillConcave, which runs a per-scanline pass over the whole
filled region. For a simple area under an x-monotone curve that work is
unnecessary.

- A new helper fills the area between an x-monotone polyline and a
  horizontal baseline directly as a triangle strip, in one pass over the
  points. The market sparklines, the market price chart and the mining
  hashrate sparkline all use it. The fill is flat and non-anti-aliased;
  the anti-aliased curve drawn on top hides the stepped top edge, and
  the faint side and bottom edges are imperceptible at these alphas.

Tests: the strip's vertex and index counts, index bounds, and that its
triangle area matches the trapezoid area under the polyline.

DanSandClaude Opus 4.8 944fafa1c7 perf(explorer): fetch each block with one RPC and back off on failure
Each recent block was fetched with two round trips (getblockhash then
getblock), and a height that failed, such as one briefly above the tip
during a reorg, was refetched on every frame.

- getblock is now called once with the height directly, falling back to
  the getblockhash plus getblock pair only when an older daemon answers
  "not found" for the short string; any other error is a real answer.
- A failed fetch backs off with a doubling wait (2 s up to 32 s) before
  any new fetch is scheduled, and a successful fetch resets the backoff.

DanSandClaude Opus 4.8 c3f981b52e fix(history): keep the open detail row across paging and filtering
The inline detail panel was tracked by the filtered list index. The
display list is rebuilt and re-sorted on every data change, sort switch
or filter edit, so a stored index pointed at a different transaction
after the rebuild, and a page reset was triggered by any change in the
row count, bouncing the view back to page 1.

- The open row is now tracked by a stable content key (txid, display
  type, address and the amount's exact bits) so the right row stays open
  across rebuilds.
- The page resets and the open row collapses only when a filter input
  changes (type, sort or the full search text). A new or removed row is
  data and now just clamps the current page.
- The open row is also cleared on page navigation and when the list
  empties, so a wallet switch does not resurrect an old expansion.

Adds pure helpers rowKey/filterInputsChanged to
transactions_tab_helpers.h.

Tests: rowKey distinguishes each field and separates +0.0 from -0.0, and
filterInputsChanged latches each input change but not the first frame.

DanSandClaude Opus 4.8 a5e4fd5c02 perf(history): group transaction rows by txid once per change
The History tab built a txid-to-indices map twice when its inputs
changed, once for the summary-card totals and once for the display list,
each a full pass over every transaction with string-keyed hashing.

- The rows are now grouped by txid a single time whenever the
  transaction list changes, into an index-only structure (first/next
  chains with no string copies), and both the summary pass and the
  display pass reuse it. A sort-combo change re-sorts without regrouping.

Adds a pure, unit-testable groupByTxid helper in
transactions_tab_helpers.h.

Tests: the chains match a reference map over a random id stream, and the
empty and single-row cases.

DanSandClaude Opus 4.8 01b59d24db perf(image-picker): cull off-screen thumbnail cells
The image picker laid out and drew every cell in the directory and image
grids, including the many cells scrolled out of view.

- A cell whose rectangle is not visible now reserves the same space with
  a dummy of the cell size, so the scroll extent is unchanged, and skips
  the hit-test and draw.

No visible change; only off-screen cells are skipped.

DanSandClaude Opus 4.8 3ca7a5c90e perf(explorer): cull off-screen rows in the block detail list
The block detail modal drew every transaction row of a block, running
the hit-test, the draw and a hash truncation for each one, even when the
row sat far outside the scroll viewport.

- A row entirely outside the scroll clip now keeps its layout slot (so
  the scroll extent is unchanged) but skips the hit-test, draw and hash
  truncation. The expanded row is always laid out so its inline detail
  panel still appears.
- The old "showing first 100 of N" footer is dropped, since every row is
  now cheap to lay out regardless of how many a block has.

No visible change; only off-screen rows are skipped.

DanSandClaude Opus 4.8 b8a4a11f90 fix(console): keep JSON folding active under channel filters
JSON folding in the console was bypassed in any filtered view, including
when only a channel toggle (daemon, RPC or app) was active. A collapsed
block silently expanded the moment a channel was toggled.

- Folding is now kept active unless the view is text-filtered or
  errors-only, which are flat so that every match stays reachable.
  Channel toggles keep folding, since JSON blocks are atomic per channel.
- The fold triangles and the collapsed " ... }" summary are drawn only
  in the fold-aware view, so the glyph and the rendered block can never
  disagree.

User-visible: JSON results stay foldable while channel filters are
applied.

DanSandClaude Opus 4.8 c1b289cc27 perf(console): cull off-screen wrapped rows
A long wrapped console line could extend far past the viewport, yet
every sub-row was still measured and drawn.

- Sub-rows that fall entirely outside the clip rect are now skipped. The
  per-row ordinal still advances for a culled row, so scanline parity is
  unchanged.

No visible change; only off-screen rows are skipped.

DanSandClaude Opus 4.8 f7ed1ae115 perf(console): tail-cap large RPC results without a full copy
A large RPC result was fully split into lines and copied before being
handed to the console, even though only the last few lines could survive
the model's line cap.

- The formatter now takes a line cap and keeps only the last N lines,
  located by a backward newline scan, so a huge result is never fully
  split or copied. JSON classification still keys off the first
  character of the whole result.
- It works over a string view and moves line text through, and fold
  spans are computed over the formatted lines directly instead of a
  separate vector of copies.
- getline semantics are preserved: a trailing newline adds no empty
  line and an empty result yields no lines.

Tests: getline parity for empty, trailing-newline and blank-line inputs,
the backward tail cap, and JSON classification and fold spans over a
capped result.

DanSandClaude Opus 4.8 116a997a3a fix(console): bound the pending queue by lines and bytes
The console's pending, not-yet-drained queue was unbounded, so a hidden
Console page that kept receiving verbose daemon-log chunks could grow
without limit.

- Pending lines are now bounded by both a line count and a byte budget.
  The oldest pending lines are dropped once either is exceeded, while
  the newest line is always kept so one huge line is never lost.
- A formatted RPC result is ingested as one block under a single lock,
  so lines from other producers can never interleave inside it.

The front-sequence accounting is also corrected: a pending line dropped
by the cap never entered the visible buffer, so it no longer advances
the front sequence. Only a front eviction or a clear does.

Tests: the line and byte caps keep the newest lines, a single oversized
line survives, a batch appends contiguously, and the front sequence
advances only on a front eviction or clear.

DanSandClaude Opus 4.8 70e96f75f0 perf(console): case-insensitive filtering without per-line copies
Console text filtering and match highlighting lowercased a full copy of
every line, and of every drawn segment, on each pass.

- A new alloc-free ASCII case-insensitive substring search folds both
  sides on the fly, so neither the filter test nor the highlight scan
  allocates a lowercased copy per line any more.
- Both call sites use it; the case-insensitive match behaviour is
  unchanged.

DanSandClaude Opus 4.8 6a24355c79 fix(console): release busy gate when the fast worker stops
When the daemon disconnects, teardown stops the fast RPC worker without
draining its queued main-thread callbacks. The console busy gate was
released inside that callback, so a command whose callback was discarded
left the input disabled for the rest of the session.

- The busy gate now drops from an RAII guard at the end of the worker
  job itself, so it is released however the job ends: success, error, or
  a worker torn down undrained.
- The result is published to the console before the gate drops, so a
  freed-up console always has the output queued.
- An unknown, non-std::exception failure is now caught and reported
  instead of escaping the job.

User-visible: the Console input can no longer stay stuck disabled after
a reconnect.

DanSandClaude Opus 4.8 8255923f33 fix(settings): scope portfolio groups by wallet identity
Market-tab portfolio groups were tied to a wallet by a hash of its
address set. That hash changed whenever an address was added, so a
group built for a wallet could silently drop out of view once the
wallet gained a new address.

- Groups are now scoped by the wallet's stable id, which is persisted
  and never derived from the address set, so adding an address can no
  longer orphan a group.
- An older build's address-hash scope fails open (the group stays
  visible) and is migrated once per wallet per session to the stable id.
  A legacy group is claimed when its old hash matches, when one of its
  own addresses belongs to this wallet, or when only one wallet is
  known; anything ambiguous is left legacy and stays visible.
- Scope filtering waits until the wallet's addresses are loaded, so a
  group never flashes an empty 0.0000 balance and Add stays disabled
  until the wallet is resolved. This works on Lite, which never stamps
  an address-update time.

Behaviour: an older build opened after this change hides groups tagged
with a stable "w:" scope (they are not deleted and return on the next
upgrade) - worth a release note.

Tests: group visibility across global, stable and legacy scopes with the
wallet resolved and not; the migration rules (hash match, address
overlap, single-wallet claim, ambiguous left alone, idempotent); and a
save/load round trip where an address-set change cannot orphan the scope.

DanSandClaude Opus 4.8 c3ffc97b31 fix(ui): finish a stranded bootstrap even when its dialog is closed
A Settings bootstrap was only wrapped up inside the dialog's own draw
path. If the dialog finished downloading, verifying or extracting while
the user had clicked away or minimized the window, completion was never
processed: the connect and reconcile gate stayed held and the
post-bootstrap rescan was never armed.

- Completion is now a pure decision driven from a pump() that both the
  per-frame update and the dialog's render call, so a finished bootstrap
  is handled every tick whether or not the dialog is drawn.
- With the dialog open the behaviour is unchanged: it advances to the
  Done or Failed screen and those screens still own the gate. With the
  dialog closed, pump() releases the gate itself and shows a success or
  failure toast; a user-cancelled run is released silently.

User-visible: a bootstrap started from Settings now completes, arms its
rescan and reports its result even if the dialog is closed or the window
is minimized when it finishes.

Tests: the completion decision for an unfinished worker, a completed run
with the dialog open and closed, a failed run, and a user-cancelled run.

DanSandClaude Opus 4.8 d4339be94b fix(ui): keep a chosen send-from address from auto-select overwrite
The Send tab auto-selected the highest-balance address on first load.
When another tab had already pre-filled the source with "Send from this
address", that first-load pick overwrote the user's choice, and the
dropdown's selected index could drift out of step with the address that
would actually be debited when the address list changed.

- The send-from string is now the single source of truth. The one-shot
  auto-pick only fills an empty source and never replaces one the user
  or another tab set, and the list index is re-derived from the string
  each frame so it cannot desync.
- An explicit "Send from this address" choice latches the auto-pick off,
  so the first visit cannot undo it.
- A chosen source the dropdown does not list (zero balance, view-only,
  or the list still loading) now previews the address that will be
  debited instead of the "Select a source" placeholder.

User-visible: a send-from address chosen from another tab survives the
first load and later refresh ticks.

Tests: the source resolver keeps a pre-fill on first visit, fills an
empty source with the best spendable address, keeps a source missing
from a short list with index -1, latches nothing while disconnected or
with an empty list, and re-derives a stale index from the string.

DanSandClaude Opus 4.8 579accd0c6 fix(ui): validate shielded addresses with the correct RPC
The Validate address dialog chose its RPC from the first character of
the input, then asked the transparent-only validateaddress for every
case. That RPC is Base58-only, so a valid Sapling (z) address came back
isvalid=false and was reported invalid.

- The input is now classified with the checksum-verified recognizers,
  and a shielded address is sent to z_validateaddress while a
  transparent (mining) address keeps validateaddress.
- Anything that is not an address - a typo, garbage, or a pasted
  viewing/spending key - is judged invalid on the spot and never sent to
  the node, so a key pasted into the field is not leaked to an RPC.
- On Lite there is no node to ask, so the dialog shows the checksum
  verdict alone and hides the "owned by this wallet" row.

Tests: validateRpcMethod maps shielded to z_validateaddress, transparent
to validateaddress, and a key or empty string to no RPC.

DanSandClaude Opus 5.5 e7f084e3eb fix(bootstrap): harden archive names, the cancel window and quit wait
The bootstrap preflight's protected names could be bypassed by names
that resolve onto them, and its cancel and quit paths had two timing
gaps.

- Entry names are judged as the file system resolves them: '\' is a
  separator, "." components are dropped and each component loses its
  trailing dots and spaces, as Win32 does ("./wallet.dat" and
  "DRAGONX.conf." name protected files). The whole archive is refused
  for an absolute or drive-rooted name, a ".." component, any ':'
  (drive letter or NTFS alternate data stream, "DRAGONX.conf::$DATA"),
  an 8.3 short name ("DRAGON~1.CON"), a component of only dots or
  spaces (other than "."), and any byte >= 0x80 or ASCII control
  character: macOS folds or ignores some Unicode (U+017F, U+212A,
  U+200C) onto a protected name, and the published bootstrap archive
  uses plain ASCII names. A refused name is echoed
  with \xNN escapes. A member is written at the path it was checked
  under, and the protected-name check runs on the resolved name.
- The user's Cancel (Settings dialog and first-run wizard) goes through
  requestCancel(). It is refused once the old chain data starts being
  replaced, and the start of that window re-checks a cancel under the
  same lock, so a click lands before the old chain is touched or not at
  all.
- Quit cancels the wizard's and the Settings bootstrap when the
  shutdown starts; the HEAD and checksum requests now end at once on
  cancel, and a cancelled HEAD keeps the partial download. A run
  cancelled before the window leaves the old chain as it was. A run
  inside it stops extracting and removes its partial chain while the
  shutdown screen shows "Cleaning up...", so it ends with no chain data
  (wallet.dat untouched; Retry reuses the zip, or the node resyncs).
  That wait is bounded: at most 2 minutes from the start of the
  shutdown, then 3 s in shutdown(), after which a worker still running
  is left to the process exit. Only a cleanup that overruns that cap
  can leave a partial chain, which dragonxd then answers with its
  reindex offer.

Tests: refusal of the Windows-resolved, non-ASCII and control-character
names with the escaped echo; the protected-name list incl. the resolved
forms and a planted -wallet file, conf and database/ that stay
byte-identical; the user-cancel window; the bounded quit wait and
safeToAbandon(); a cancel ends a HEAD request that never answers.

DanSandClaude Opus 5.5 a581f42a33 fix(settings): disable the unimplemented Tor option and tell its users
The "Use Tor" checkbox was saved but never read: no build routed any
traffic (node, RPC, price/update/bootstrap/pool HTTP or Lite gRPC)
through Tor, so users who ticked it believed they were anonymous.

- The checkbox is disabled and always shown unticked, on the Settings
  page and in the legacy Settings window. Its tooltip says it is not
  available and gives the alternatives: for the node, proxy=127.0.0.1:9050
  in DRAGONX.conf with Tor running; otherwise a system-wide VPN/Tor (Lite
  builds get the short version). The "Use Tor" label is kept.
- Behaviour change: a stored use_tor=true is cleared once at startup
  (Settings::consumeLegacyUseTor + a synchronous save before the async
  writer and any Settings page state), with a 20 s warning in the user's
  language. The cleared key is the "already told" flag, so the notice
  never repeats. No settings format change.
- 3 new strings (tt_tor_unavailable, tt_tor_unavailable_lite,
  tor_never_applied_notice) in all 8 languages; the tooltip wraps at
  tor-tooltip-wrap-width from ui.toml.

DanSandClaude Opus 5.5 81733f5603 fix(rpc): run rescans and key imports without the 30 s timeout
A rescan or key import holds the node's cs_main for the whole wallet
scan. On the shared clients it hit the 30 s curl timeout, reported a
failure that wasn't one, abandoned a daemon RPC slot and flipped the app
into "node busy".

- One long wallet RPC at a time (rescan, importprivkey, importaddress,
  importwallet, z_importkey, z_importviewingkey, z_importwallet) runs on
  its own ungated client with no client timeout (rpc/long_call_lane.h).
  It can be aborted from any thread, and an abort is never lost, even
  one that lands before the client opens.
- The GUI rescan, key import and sweep use it. The sweep's fund-moving
  body is unchanged; only the client it calls differs. runtimeRescan()
  returns bool, and a refused post-bootstrap reconcile stays armed.
- The console routes rescan and the import commands through the lane;
  its input stays usable meanwhile, and a refusal is printed like any
  other result. RPCClient gains callRaw(.., timeoutSec).
- Restart, wallet switch, delete-chain, bootstrap (now also from
  Settings) and the other node-stopping flows are refused while it runs,
  with a message saying a key import or rescan is still running; quit
  asks for confirmation. The lane is aborted at quit.
- A second import or rescan is refused before the key is copied anywhere.
  An import cut off after the request reached the node (a lost reply,
  or a proxy's 502/504 while the node still imports) says the key may
  already be in the wallet and to run Settings -> Rescan. Only the
  node's own HTTP-layer refusals (401, 503, work queue full, unhandled
  request) say that the key was not imported. A pure
  classifyLongCallCutOff() makes that choice.
- New strings in all 8 languages; console results stay English.

Tests: the long-method list and the console's routing; one lane at a
time; an abort lands whether it comes before the client opens or during
the call; a call with no client timeout outlasts a 3 s scan, where a 1 s
gated client times out and marks the node busy; classifyLongCallCutOff()
for every failure kind with and without a sent request, and from raw
HTTP replies (502, 504, a plain 500 -> cut off; 401, 503, queue full,
unhandled -> refused).

DanSandClaude Opus 5.5 78e38570a8 fix(bootstrap): check archive and free space before deleting chain data
The bootstrap removed blocks/, chainstate/ and notarizations/ first and
only then opened the archive. An unsafe entry, a full disk or a corrupt
member therefore left no chain, or a half-written one for dragonxd to
start on.

- Preflight before anything is deleted: every archive entry must be
  safe (no absolute path, no "..") and readable, and the disk must hold
  the extracted size plus max(256 MiB, 5%), counting what removing the
  old chain frees (a symlinked chain dir counts 0). Free space counts as
  unknown only when the probe errors, the capacity is 0 or the
  available size is -1; a known disk with 0 bytes free is a refusal.
  The old chain is kept on every preflight failure.
- Protected members are skipped, compared case-insensitively: any path
  component starting with "wallet", any "database" component, a .cookie
  or *.conf file, and top-level *.dat files other than fee_estimates,
  peers and banlist. The number of non-critical member failures is
  logged.
- The removal of the old chain is verified (a locked file fails the run
  instead of mixing old and new chain files). If the extraction fails or
  is aborted, the partial chain is removed again before the failure is
  published; isDone() turns true only after the worker's last
  filesystem change.
- Cancel is disabled while the old chain data is being replaced, and
  quit aborts a running bootstrap.
- A complete zip from an earlier attempt is reused on Retry; its
  checksum is re-verified. A download that cannot fit fails early, and a
  disk-full write error says so.

Tests: the space rule (boundaries, unknown vs. full disk, saturation);
planArchive sizes, zip-slip, garbage and truncated zips; the
protected-name list; reclaimableBytes with symlinks; each preflight
refusal keeps the old chain and wallet.dat byte-identical; a corrupt
critical member removes the partial chain before the failure is

DanSandClaude Opus 5.5 62a5577491 fix(sweep): keep the UI sweep away from real wallet data
The full UI sweep (dev builds only) ran its demo surfaces against the
real profile. Its teardown deleted wallet-{cold,trading,mining,donations,
2023,payroll}.dat from the real datadir, it created zero-filled wallet
files and picker-demo/extra-wallets folders, its demo wallet-index upsert
re-minted the active wallet's scopeId (hiding "w:"-scoped contacts), the
Contacts tab could re-attach legacy-scoped contacts to such a throwaway
id in addressbook.json, and it persisted the demo active wallet file and
Mining pool worker.

- Preflight: a full sweep is refused (toast + log line) while a real
  workflow is in flight: a pending seed_migration_* setting or open
  migrate dialog, a wallet switch, an encryption/import workflow, an
  encrypt/PIN/lock operation, the seed-backup dialog, or a bootstrap.
  The DRAGONX_FULL_SWEEP hook then exits as for an empty catalog.
- Persistence latches: AddressBook (snapshot on the first sweepBegin,
  save/load latched while a demo-contacts surface is shown), WalletIndex
  and Settings (active wallet file, contacts view mode, pool URL/worker)
  for the whole sweep. Settings::sweepEnd() is the last statement of
  clearDemoWalletData and flushes once only if a save was suppressed; a
  quit mid-sweep writes nothing to the profile (the 0700 sandbox, with
  zero-filled demo files only, may stay in the temp dir).
- Scope ids: during a full sweep activeWalletScopeId() returns the
  persisted id or "" and never mints one, so the Contacts tab cannot
  move legacy-scoped contacts to a throwaway id. The only address-book
  write a sweep can still cause is the one-time legacy re-attach to the
  wallet's persisted id, which opening Contacts does anyway.
- Sandbox: demo wallet files and folders go to a fresh random 0700 dir
  under the temp dir (exclusive create, a pre-existing path or symlink
  is refused), removed at sweep end. The teardown that deleted those six
  wallet files is gone.
- Cleanup: the migrate-to-seed state, wizard phase, demo chat
  conversations and a fabricated demo chat identity are reset at sweep
  end; the seed-backup surface always shows the demo phrase and a real
  z_exportmnemonic result is dropped while the sweep runs.
- i18n: one new key (screenshot_sweep_refused) in i18n.cpp and the 8
  language files.

Tests: the address book snapshots only on the first sweepBegin, keeps
addressbook.json byte-identical while latched and restores the real
book; the wallet index keeps wallets.json and the real scope id, also
with the background writer attached; Settings restores the latched
values and flushes once only when a save was suppressed; the sandbox
helper refuses a pre-existing path or symlink and removes only a
prefixed dir, never a symlink's target.

Release note: v2.0.x UI sweeps could delete wallet-{cold,trading,mining,
donations,2023,payroll}.dat from the data directory and re-scope
contacts; this cannot be undone automatically.

DanSandClaude Opus 5.5 1ced49d622 perf(console): extend the filtered view incrementally
With any console filter on, each batch of new output rescanned all N
lines to rebuild the visible set. A text filter lowercase-copied the
needle and every line to test it: O(total characters) and 2N
allocations per batch.

When the filter is unchanged and the model only appended or evicted
lines since the last pass, the visible indices drop the evicted lines
and shift down, and only the new lines are tested. The result equals
a full rescan, since line text and channel never change and the
filtered view has no folds. A filter change, Clear, or a model window
that doesn't follow on from the last one still rescans.

DanSandClaude Opus 5.5 ee0a486676 perf(console): wrap only new console lines via a per-line cache
Each batch of new output re-wrapped all N visible lines glyph by glyph,
allocating a fresh segment vector per line; a line evicted at the
10,000-line cap shifted every index, so nothing could be kept. And on
every frame, idle or not, seeding the scanline shading summed the wrap
rows of every line above the view.

- The model numbers its lines and the view keeps one wrap per line,
  aligned by that number, so an eviction drops a prefix instead of
  forcing a rebuild. New output wraps only the new lines; the layout is
  then a prefix sum over the N visible lines, with no measuring and no
  per-line allocation.
- The wraps are kept while the wrap width, line height, font size, font
  (by ImFont::FontId) and rasterizer density are exactly unchanged. A
  line-spacing change only re-sums heights; filters and fold toggles
  reuse the cached wraps. A resize drag still re-wraps every visible
  line per frame, as before, but reuses their storage.
- The scanline seed is read from the prefix sum: O(1) per frame.

Heights, offsets and segments are bit-identical to the old rebuild. A
font reload at an unchanged size (the colour-emoji toggle) now re-wraps
the console at once; before, it waited for the next line of output.

DanSandClaude Opus 5.5 c2c2a8325b perf(overview): clip the address list to the visible rows
The Overview address list built all N rows on every frame (icons,
labels, balances, buttons, an InvisibleButton and a context-menu
check per address) and allocated a vector of N row positions, however
few rows fit on screen; the edge mask then walked all their vertices.

An ImGuiListClipper now submits only the rows that intersect the
list's clip rect, plus:
- one guard row on each side, so dividers and anti-aliased edges at
  the clip boundary are drawn as before;
- the row being dragged and the row whose context menu is open, so
  drag-to-reorder and the menu keep working when they scroll away;
- the rows keyboard navigation targets (kept by the clipper itself).

Before each row the cursor is put back exactly where the unclipped
loop left it, so the density-scaled spacing, which depends on the
cursor position, and every row's geometry are unchanged. Row tops are
computed from the index, so the per-frame vector is gone, and the
scroll extent is the same. The row model (sort, filter) is still
rebuilt over all addresses each frame.

DanSandClaude Opus 5.5 88fa13dd1a perf(mining): sample system RAM at most once a second
The Mining tab's memory bar read used system RAM and the wallet's own
memory on the UI thread every frame: synchronous OS queries, on Linux
an open and parse of /proc/meminfo and /proc/self/status per frame.
Both are now sampled at most once a second; the first frame after
more than a second idle resamples at once. Total RAM was already
cached and daemon RAM already comes from a background sampler.

The used-RAM and wallet-memory readings in the bar and its tooltip now
refresh at most once a second; what they show is unchanged.

DanSandClaude Opus 5.5 888a41ddc2 perf(mining): memoize the earnings card on tx_revision
The Mining tab's earnings card walked all N wallet transactions on
every frame to total Today / Yesterday / All time and pick the 4 most
recent rows: four string compares per transaction plus a memo search
on receives. It also ran localtime and mktime every frame to find
local midnight.

The pass is now a pure function behind a one-slot cache keyed on
WalletState::tx_revision, the transaction count, the filter pill, the
Solo/Pool mode, solo support and local midnight, with a 2 s maximum
age as a safety net. It reruns only when one of those changes or the
2 s age runs out, instead of every frame. The totals are bit-identical
(same loop, same summation order), and crossing local midnight still
moves Today into Yesterday at once.

Local midnight is recomputed only when the clock second changes,
through the shared util::localTime; a failed localtime now yields a
zeroed struct instead of an uninitialised one. The "x ago" labels and
Est. Daily are still computed per frame.

DanSandClaude Opus 5.5 3069151e7f fix(chat): bound the selection copy range to the message body
The copy button of a text selection in a chat bubble copied
body.substr(start, len) with byte offsets kept from earlier frames.
Those offsets can outlive a thread change (an older message inserted
above shifts the message indices, so the selection can land on a
shorter body), and a start past the end made substr throw
std::out_of_range out of the chat render; the main loop catches it,
but the rest of that frame's UI is dropped.

The copy now runs only when the start is not past the end of the body.
substr already clamps the length, so the copied text is the same in
every case that did not throw before.

DanSandClaude Opus 5.5 4a95d9ecb7 perf(chat): lay out and draw only the visible chat thread rows
Every frame the open chat thread handled all N messages: grouping flags
from two day keys each, a measuring layout of every body, then the
draw, which laid every body out a second time and ran the bubble, hover
and popup code, however few rows were on screen.

The thread now keeps a layout cache: grouping flags, each body's
wrapped size (keyed by message, so only new or re-wrapped bodies are
measured) and each row's height, with prefix offsets. A frame binary-
searches the visible range and submits those rows plus any failed send
(Retry stays reachable with Tab), the row being drag-selected and the
row whose context menu is open; one spacer stands in for each skipped
run, and scrolling to the newest message works as before.

- Rows are rebuilt when the chat store changes or when the wrap width,
  fonts, font size, DPI scale, rasterizer density or compact mode
  change. Fonts are keyed by FontId, so a font reload at the same size
  (the colour-emoji toggle) re-measures. A rebuild is O(N), about
  0.5-1 ms at 3000 messages.
- Grouping flags are recomputed on a data change and once a minute,
  together with util::refreshTimezone(), so a system timezone change
  reaches chat timestamps within a minute.

Rows above the visible range are now one spacer of their summed
heights, so the visible rows no longer move by a pixel each time a row
above them crosses the top of the app window. Debug builds log once if
a cached wrap width or row height ever disagrees with the live layout.

DanSandClaude Opus 5.5 a69380817e perf(chat): use reentrant local time for chat timestamps
The open chat thread called std::localtime at least twice per message
per frame (two day keys for grouping), and more for day separators and
time labels. On glibc every call re-checks the timezone with a stat of
/etc/localtime. The chat time helpers now use util::localTime() from
the new util/local_time.h: localtime_r (localtime_s on Windows), with
no per-call timezone check and no shared static result buffer.

glibc's localtime_r reads the timezone only once, so local_time.h also
adds util::refreshTimezone() (tzset) for caches to call when they
rebuild. Nothing calls it yet; its first caller is the chat thread's
grouping-flags cache in the next commit.

DanSandClaude Opus 5.5 e45f4c7d90 perf(history): key History caches on tx_revision and memoize the filter
Every frame the History tab:

- hashed the txid, amount, confirmations, time, type and address of
  all N transactions (about 0.6-5 ms at 5k-20k) to decide whether its
  totals and its merged, sorted row list were stale;
- copied every chat txid into a fresh set;
- ran the type and search filter over all N rows, with up to three
  case-insensitive substring searches each.

The totals and the row list now key on tx_revision (the row list also
on the sort mode), the Message badge and the Chat filter use the chat
store's txid index, and the filtered rows are rebuilt only when the row
list, the type filter, the search text or, under the Chat filter, the
chat store changes. A frame is now a few compares plus one txid lookup
per row of the current page. An unchanged full-node refresh no longer
rebuilds the totals and the row list either: the old fingerprint folded
in the refresh time.

On lite, a change to only a memo or a sender address now shows at once.
The old fingerprint left those fields out and relied on a refresh time
that lite never sets, so such a row stayed stale until something else
in the list changed, such as the next block.

DanSandClaude Opus 5.5 4a2a1bdd54 perf(image-picker): decode thumbnails off the UI thread
The image picker decoded up to 6 full-size images per frame on the UI
thread to make its thumbnails (1.5-2.7 s per frame with 12 MP photos,
until the visible grid filled) and read every .gif/.webp a second time
just to see whether it animates. Thumbnails were freed only on navigate
or close, so a large folder and every hovered animation (up to ~20 MB
each) stayed resident.

Thumbnails now decode on util::StartImageDecode workers (at most 2 at
once, so the top of the visible grid fills first) and the UI thread
uploads up to 8 small textures per frame. The animation badge comes from
the same decode, with no second read. Hover previews get their own
2-slot lane, and the picker asks for a frame every 100 ms while anything
is pending; under idle pacing a deferred thumbnail used to wait for input
or the 2 s tick.

Behaviour changes:
- thumbnails and hover frames are LRU-capped at 64 MiB per folder;
  evicted ones re-decode when they are needed again;
- leaving an animated thumbnail before its preview finishes decoding
  cancels it (re-hover restarts it); a finished preview is kept;
- animated WebP files get a real thumbnail instead of the placeholder;
- images above the decoder's limits show the placeholder.

DanSandClaude Opus 5.5 3af7b0ef44 perf(contacts): decode avatars off the UI thread
The Contacts tab read, decoded and downscaled custom avatars inside the
draw call, two per frame, rows scrolled out of view included: a 12 MP
photo froze the window for 0.25-0.45 s, a long GIF for up to 1.5 s, and
the avatar cache was never evicted. "Add image" decoded the picked file
and copied it inside the picker's confirm callback, freezing it again.

Avatars now decode on util::StartImageDecode workers (at most 2 at once).
The UI thread only uploads finished frames, at most about 4 MB per UI
frame, and asks for a frame every 100 ms while anything is pending;
under idle pacing a deferred avatar used to wait for input or the 2 s
tick.

Behaviour changes:
- an avatar scrolled out of view is not decoded until it scrolls in
  (the badge shows for 0.1-0.3 s the first time);
- avatar textures are LRU-capped at 128 MiB; the least recently drawn
  go first, never one drawn on-screen in the previous Contacts frame,
  and they re-decode on scroll-back;
- an animated avatar starts playing once all its frames are uploaded;
- an import is validated and copied on a worker: the avatar appears
  0.1-0.5 s after confirming and Save/Add stays disabled until it does;
  a result only lands in the dialog session that started it;
- the copy goes to a temporary file renamed over the target (retried
  briefly), so a crash or a failed copy never leaves a truncated avatar
  or removes the existing library image;
- imports get the decoder's limits, and an animated WebP can now be
  imported (it always failed with "couldn't be loaded").

Applying an import also no longer destroys an avatar texture the same
frame has already drawn (a use-after-free on DX11).

DanSandClaude Opus 5.5 a700d2c7ee perf(wallets): walk added wallet folders off the UI thread
Every open of the Wallets dialog, Refresh, folder add or remove, and Open
on a stale row walked each user-added folder recursively on the UI thread
before the dialog drew: up to 40,000 entries per folder, roughly
50-150 ms warm on Linux and seconds on a cold disk, a network share or
Windows.

The datadir listing (a few top-level files) stays synchronous, so a
wallet just created shows at once. The recursive walk runs on a detached
worker with the same depth, hit and entry limits; its rows are merged at
the start of a later frame and only the new rows are probed.

- The dialog opens at once with the datadir rows. The external rows
  arrive when the walk ends, with "Scanning folders..." beside the
  scanned-folders caption, and the card grows once.
- Reopening within 60 s with the same folders reuses the last walk
  without touching the disk, so its rows and sizes can be up to a minute
  stale: a wallet copied into a folder in that minute needs Refresh.
  Refresh and Open on a stale row always walk again.
- While a walk or a wallet probe runs (up to 30 s) the dialog keeps
  frames coming, so rows and badges appear without moving the mouse.
- The 200-row cap now holds across all folders; each extra folder could
  add one row past it.

held a reference to that row and walked a sort order sized for the old

now flags a rescan for the next frame; the vanished row drops out one
frame later, with no crash.

DanSandClaude Opus 5.5 55975901a2 perf(lite): move wallet ops and server switches off the UI thread
New address, Import key, Encrypt and Remove encryption called the
backend on the UI thread. Each ends in the backend's save, which waits on
the lock a scan holds for its whole duration and every refresh read holds
briefly, so during a scan the window froze until the scan ended. A create
or restore with a passphrase encrypted and saved just after its first
scan had started: for a restore, a freeze for the whole initial scan. A
server switch destroyed the old controller on the UI thread and joined
its refresh worker, which can sit for minutes in a read against a dead
server (each balance, notes or list read retries for ~62 s).

- The four ops run one at a time on a background lane and their results
  are applied on the main thread; Settings shows "Working…" meanwhile.
  Key and passphrase copies are wiped after the call, or when a queued
  op is dropped.
- A create or restore encrypts and saves (an open unlocks) before the
  first scan starts, so the save takes milliseconds and the scan runs on
  the encrypted file.
- Import, Encrypt, Remove encryption and Receive's New address are
  disabled while a scan runs ("Wait for blockchain to sync"); Redownload
  blocks is disabled while an op is queued.
- A switch retires the old controller without blocking (queued ops
  dropped, pending ones reported failed, its client shut down) and
  destroys it on a background thread. It no longer saves on the way out:
  the new client re-scans the blocks since the last save, as after a
  restart.
- A switch waits for an op in flight, at most 15 s, so the op can't
  finish and save on the old client while the new one owns the wallet
  file. The Network tab already shows the new selection meanwhile.
- The refresh worker stops between backend commands, skips the remaining
  server reads once one fails, and then retries after 4, 8, then 15 s
  instead of every 2 s.
- Quit waits up to 2.5 s for an op in flight, e.g. Encrypt's save.

Encrypt and Remove encryption now report a failed save: the backend
returns it as a JSON error that the old check never saw, so the failure
was reported as success. The trimmed copy of a key typed into Import is
now wiped too, and stopping the refresh worker can no longer miss its
wakeup.

DanSandClaude Opus 5.5 296c04386c perf(mining): sample daemon memory off the UI thread
The daemon's RSS was read on the UI thread: a scan of every /proc entry
on Linux (1-7 ms), a forked ps on macOS (up to ~30 ms). The mining poll
probed every 1-5 s on every tab, and the Mining tab's memory bar probed
again every 1.5 s.

util::BackgroundSampler now runs the probe on one lazily started thread
and caches the result. getDaemonMemoryUsageMB() returns the last sample
and asks for a new one at most every 3 s, and only while the Mining tab
memory bar or the Peers tab Memory cell is drawn: nothing on other tabs
or while minimized. EmbeddedDaemon::memoryProbe() hands the sampler a
pid snapshot (on Windows the value read from the owned process handle),
so nothing off-thread touches daemon state. The mining poll does no I/O
any more; it carries the last sample. Both shutdown paths stop the
sampler.

Fixed along the way: an unreadable /proc made the directory iterator
throw on the UI thread; the scan now just stops.

User-visible:
- the Peers tab Memory cell keeps updating during sync and shows an
  external daemon's memory (it showed the mining poll's value, which
  pauses during sync and covers only the embedded daemon);
- the Mining tab memory bar refreshes every ~3 s (was 1.5 s).

The thread grid is inert during a benchmark, but the -/+ buttons and the

while the benchmark owned the miner's (before the previous commit it
also restarted xmrig at that count and spoiled the measurement). The
buttons and the field are now disabled until the benchmark ends.

DanSandClaude Opus 5.5 6c02e67c6d perf(mining): one save, at most one restart per thread-count gesture
Every thread-count change on the Mining tab saved settings.json and,
with a miner running, stopped and restarted it: xmrig re-inits its
RandomX dataset and reconnects to the pool, seconds of lost hashing
each time. A drag across the grid did this once per tile crossed (up to
~24), with a "Starting pool miner" toast each; every -/+ click or Enter
did it again.

The tab now hands each pick to the App, which puts the newest in
settings at once and applies it when the input settles: on drag
release, or 0.5 s after the last click, even if the Mining tab was left
in the meantime. The header, RAM estimate and tile fill still follow
the drag live.

- Pool: the restart is decided on the mining-control thread, after every
  earlier start or stop has run. It never starts a miner the user
  stopped, is a no-op when xmrig already runs at that count, and is no
  longer silently skipped when the pick lands in another restart's stop
  window (which left xmrig on the old count).
- Solo: one setgenerate per gesture. A pick made while one is in flight
  now waits for it instead of being dropped (another stale count).
- Clicking the tile that is already selected does nothing; it used to
  save settings and restart the miner.
- With idle thread scaling on, the grid no longer snaps back to the old
  count while a pick is on its way to the miner. A pool auto-balance
  restart keeps a count still queued.
- Idle thread scaling changes the pool count through the same retarget.
  Its correction after a start compares with the count last requested,
  not the xmrig API's lagging report, so it comes about 1 s in instead
  of after the first API report (3-5 s).
- A retarget whose pool config no longer validates shows the same error
  and stops the miner, as the old stop-then-start did.
- While a benchmark runs a pick is saved, but the miner change is
  dropped: the benchmark owns the count until it ends.

A crash within 0.5 s of a pick, or mid-drag, loses that pick; every
clean exit saves it.

The value still applies live and is kept in Settings for the per-frame
readers; settings.json is written once, when the slider is released, as
the blur and font-scale sliders already did. A drag cut off before its
release (a dialog closed mid-drag) is persisted by the next save or at
exit.

DanSandClaude Opus 5.5 cee8b9d7f6 feat(merge): run per-address consolidation as a paced background job
"Keep in each address" posted one task that called z_mergetoaddress for
every batch of every address back to back; each call is a whole-wallet
scan under cs_main, and the daemon runs the ops one at a time anyway.
It is now an App-owned services::ConsolidationRun:

- one RPC at a time; the next merge only after the previous batch left the
  queue and a gap as long as the last call took (2-120 s);
- pauses while the node syncs, the wallet is locked, a send of ours is in
  progress, or another wallet scan is running;
- failures classified: nothing that may have queued is ever resent; a
  breaker stops after 3 dead addresses or 3 failed ops in a row;
- each merge is charged to the scan budget; one re-read and one forced
  balance at the end;
- it keeps running when the dialog closes: a status-bar chip, a run view
  with progress, the wait reason and a Stop button.

The "Into one" merge can no longer be confirmed twice while its call is
in flight. fake_dragonxd gains FAKE_SCAN_SECS, FAKE_MERGE_SERIAL and
FAKE_MERGE_FAIL.

when the node is behind). Waiters are served first in, first out, with a
head start for what the page shows and a starvation floor of max(30 s
visible / 900 s hidden, 15x the stream's cost). Explicit work (a dirty
set, the user's send, a first load) is never refused but is charged.

Routine scans run only when the tip, the mempool size (getmempoolinfo:
no cs_main) or a wallet-mutation epoch changed since their last good scan,
or a safety sweep is due. Pages that don't show the balance poll it at
most every max(10 min, 50x its cost) (2 min with client-side auto-shield);
coming back into view with an old value fetches it at once. The staleness
badge counts from the last poll that confirmed nothing changed, and hides
while the budget holds the balance within its guarantee.

DanSandClaude Opus 5.5 8b9a498eee perf(net): one balance scan per poll, filtered opstatus, a guarded merge scope
The Core poll ran z_gettotalbalance twice (minconf 0 and 1), each a whole-
wallet scan under dragonxd's cs_main. The spendable (minconf=1) call now
runs only after the display call succeeded, and only when something is
unconfirmed or pending or the exact total moved: about 95% of polls make
one scan instead of two. A forced post-send balance can no longer be lost
to a refused enqueue, and pending-send debits aren't re-applied each tick.

z_getoperationstatus is filtered to our opids with its real argument form
([[id,...]]; the old ["id"] was rejected), falling back to the unfiltered
call if a daemon refuses the filter. The Shield/Merge dialog's own polls
are filtered and session-guarded too, and finally reach Done; the dead
RPCClient wrappers are deleted.

The Merge/Consolidate scope scan becomes a tested state machine: one scan
at a time, failures latch behind a Retry button, only "node not ready"
retries by itself (10/30/60 s, at most 3), Lite never scans. Its 120 s
calls are maintenance calls: every main-thread disconnect aborts one in
flight first, so a lifecycle action no longer freezes the UI behind it.
An aborted merge that was already sent says it may still go through.

DanSandClaude Opus 5.5 7ceff1eaaa fix(market): back off failed market fetches instead of retrying every frame
The Market tab calls the exchange-list, price-history and candle
fetches every frame, so a failed fetch (offline, rate-limited, a
venue's API down) was retried on the very next frame, ~20 requests a
second.

- util::FetchBackoff: 30 s doubling to a 10 min cap, +/-20% jitter.
  The exchange list, the price history (a partial result counts as a
  failure) and the per-pair candles each back off on failure.
- Candle backoff is per pair. Switching to another pair still loads at
  once, a failed refresh keeps the on-screen pair's last candles, and
  switching back to a pair that is backing off shows the aggregate
  chart rather than the previous pair's candles.
- The Market tab's refresh button retries at once (at most every 5 s).
  A price fetch (60 s timer, no backoff) that succeeds after failing
  means the network is back, so it lifts all three backoffs.
- A partial price history no longer marks the chart loaded: with no
  fetch timestamp, the 30-minute reload gate measured system uptime
  and blocked retries for the first 30 minutes after boot.
- The exchange list goes through httpGetString (TLS verified, size
  capped) with short timeouts (5 s connect, 12 s total, as it runs on
  the shared RPC worker) instead of its own curl code. A failed fetch
  is retried; it used to be tried only once per session.

DanSandClaude Opus 5.5 16e0ee9947 perf: stop per-frame SQLite writes and console spam, make perf.log opt-in
- Explorer: the tip check runs every frame the Explorer tab is open,
  and it read both tip rows and rewrote them each time (two autocommit
  WAL writes per frame). A steady tip is now kept in memory and skips
  SQLite. A new tip writes both rows in one savepoint, so a crash
  between them can't pair a new height with the old hash. A test
  checks that 100 steady checks write nothing.
- Console: while the daemon was in the Error state the Console tab
  added its error line on every poll, i.e. every frame, re-laying out
  the whole buffer each time. It prints once per error now: on entering
  Error, when the message changes, or after another crash
  (EmbeddedDaemon::getUnexpectedExitCount(), never reset). setState
  writes the message before the state, so a reader that sees Error sees
  that error's message. The stray " ===" suffix is gone.
- perf.log: the profiler appended a block every 300 frames on every
  run and never rotated the file (tens of MB a day for a wallet left
  open). It is now off unless the app starts with DRAGONX_PERFLOG=1;
  otherwise its zone hooks are near no-ops.
