…92) Phase 2 of the spacing-policy epic (#14), per docs/SPACING_POLICY.md. Computes the two free signals from the existing suggestion results every keystroke (zero extra native calls), in a pure static helper for testability: - complete = typed word is a real dictionary word (mTypedWordValid AND source != user_typed) - prefixRichScore = fraction of candidates that are KIND_COMPLETION, [0..1] computeSpacingSignals(SuggestedWords) -> SpacingSignals; wired into setSuggestedWords to store mSpacingComplete / mSpacingPrefixRichScore. No behavior change yet — the signal-driven graceMs + two-gate Assisted tier (and the A11 insight readout) consume these next. SpacingSignalsTest: 6 cases (complete for real-dict / not for user-typed / not for invalid; prefix-rich fraction; empty). All green.
…e 2) (#96) Add a native gesture-replay harness that can consume TraceRecorder JSON fixtures and run inside the existing host CMake / ctest workflow. New files: tests/replay/trace_fixture.h Header-only C++17 fixture loader (parseFixture / loadFixture). Parses the TraceRecorder schema (version 1) into plain structs with xCoordinates() / yCoordinates() / times() / pointerIds() accessors ready to forward to Suggest::getSuggestions once blockers are lifted. tests/replay/gesture_replay_test.cpp TraceFixtureParserTest (9 enabled tests) — cover JSON parsing, accessor arrays, monotonic timestamps, coordinate bounds, escape handling, and empty-pointer edge cases. DISABLED_GestureReplayTest.ReplayHelloQwerty — compile-checked scaffold documenting the exact API seam and two concrete blockers. tests/replay/fixtures/hello_qwerty.json Seed fixture: 14-sample "hello" trace on a 1080×310 QWERTY keyboard (en-US). Consumed by TraceFixtureParserTest.LoadsHelloQwertyFromFile. CMakeLists.txt: Add target_compile_definitions(FIXTURE_DIR=...) so the file-path test resolves the fixture directory at compile time without network access. Blockers documented in gesture_replay_test.cpp (DISABLED_ comment block): 1. ProximityInfo requires a live JNIEnv* — calls env->GetArrayLength() unconditionally in its constructor; no non-JNI overload exists. Fix: add a raw-pointer constructor or a fake-JNIEnv shim. 2. Dictionary requires a compiled binary .dict asset not in the tree. Fix: bundle a small en_US dict via CMake FetchContent, or generate one programmatically using the existing v4 writer classes. ctest result: 76/76 pass, 1 disabled (GestureReplayTest.ReplayHelloQwerty)
Split from the parked A11/tuning stack. Documents the actual axes discovered on-device: tap-only vs swipe vs tap-then-swipe, and auto-finish vs auto-space vs deferred-space timing. Includes concrete presets and playtest scenarios for shortcut safety, swiped complete words, tap-then-swipe extension, correction replacement, and punctuation/deferred spacing.
#78) (#104) Follow-up proof spike after #96. Add a non-JNI ProximityInfo constructor that accepts the same keyboard geometry as raw int/float arrays, so native host tests can build a keyboard geometry object without a live JVM/JNIEnv. Adds GestureReplayHostSeamTest.BuildsProximityInfoWithoutJNI: constructs a minimal QWERTY ProximityInfo and verifies key lookup for the 'hello' trace. Attempted to enable the full replay assertion with an in-memory dict; ASAN showed the next blocker is more fundamental than a dict asset: the open-source tree has no GestureSuggestPolicy implementation, only GestureSuggestPolicyFactory, whose factory method is null in host builds. Dictionary::getSuggestions(..., IS_GESTURE) therefore crashes at TRAVERSAL->getMaxSpatialDistance(). The disabled replay scaffold now documents that real blocker. Verification (WSL / ubuntu-like): native host ctest excluding the known FormatUtils quarantine -> 77/77 enabled tests pass, 1 disabled replay assertion.

Two threads could enter the critical section concurrently because they were locking on different objects. Add an explicit `blacklistLock: Any` and synchronize on it. * perf(perf): add key= to Lazy* list items for stable identity - SearchScreen: key groups by titleRes, items by toString() - ListPickerDialog, MultiListPickerDialog: key items by toString() - LayoutPickerDialog: key by layout name - ToolbarKeysCustomizer: key by enum name - ColorThemePickerDialog: key by color name Without keys, LazyColumn uses positional keys, causing every visible item to be recomposed (and its remember slots discarded) on every search keystroke or list mutation. * perf(perf): remember() expensive computations in Composables - SearchScreen: cache filteredItems(searchText.text) so it doesn't re-run the search filter on every parent recomposition (only when the search text actually changes) - MainSettingsScreen: cache SubtypeSettings.getEnabledSubtypes() and its joinToString() output so the description string is not rebuilt on every recomposition Both lists are otherwise recomputed on every pref change, every parent state change, and every scroll-induced recomposition. * perf(perf): avoid Paint allocation per recomposition in ColorPickerDialog Wrap the Paint in remember { } and assign to the controller inside a LaunchedEffect so the Paint is created once and not allocated on every recomposition. Also avoids re-assigning the controller's wheelPaint on every recomposition. * perf(perf): stream logcat to file instead of buffering in memory AboutScreen's 'Save log' was reading the entire logcat buffer into a single String via readText(), then writing it out. For a long-running device this can be several MB and compete with the IME process for memory, risking OOM on low-RAM devices. Use useLines { } to iterate line by line and write each one directly to the output stream. The internal log is now also streamed with a for loop and explicit toString() instead of a joinToString() that builds the entire list as a single String. * perf(perf): make ReorderSwitchPreference data class stable The private KeyAndState class had var fields that were mutated in the Switch.onCheckedChange callback, defeating Compose stability and forcing LazyColumn items to be rebuilt on every recomposition. - Make KeyAndState an immutable data class annotated with @immutable - Hold the checked state in rememberSaveable(item.name) so the value survives recomposition but is per-item - Remove the in-place mutation of item.state in the Switch callback - rememberSaveable the items list so it's not re-parsed on every recomposition when the dialog is open * fix(perf): remove top-level MutableStateFlow in AIIntegrationScreen The previous top-level 'providerState' MutableStateFlow lived for the process lifetime and was mutated during composition. The state can be derived from the service on every composition (the service reads from SharedPreferences, which is cheap). - Replace top-level MutableStateFlow with a simple val read - Remove the no-op updateProviderState() function - Remove its call site in AdvancedScreen.kt The AIIntegrationScreen will pick up provider changes on the next composition (e.g. when the user navigates to it after changing the provider on the AdvancedScreen). * fix(perf): scope errorJob to the LayoutEditDialog composable The top-level 'private var errorJob: Job?' was shared between any two simultaneous instances of LayoutEditDialog, so opening a second dialog would cancel the first dialog's pending error feedback job. On configuration change the coroutine scope could be cancelled while the top-level job reference was leaked. Move the job into a per-composable remember { mutableStateOf<Job?>(null) } and cancel/assign through errorJob.value. * fix(perf): replace GlobalScope in toolbar preference listener setToolbarButtonsActivatedStateOnPrefChange used GlobalScope.launch to defer a UI update by 10 ms, waiting for SettingsValues to reload after a SharedPreferences change. GlobalScope is uncancellable and its default exception handler converts failures into silent crashes. Replace it with a process-wide scope that uses SupervisorJob (so one failure cannot tear down sibling preference updates) and a logging CoroutineExceptionHandler. The function still hops to Dispatchers.Main before touching the view tree. * fix(perf): make SettingsNavHost navigateTo scope supervised The CoroutineScope backing the navigateTo() helper used a plain Job, so a single child failure would cancel the scope permanently. Add SupervisorJob so unrelated navigation hops keep working. * fix(stability): replace !! in colorFilter() helper createBlendModeColorFilterCompat returns a nullable ColorFilter, but the helper is only ever called with the supported BlendModeCompat modes (MODULATE, SRC_IN). Replace the !! with a Kotlin error() that throws IllegalStateException with a useful message if a new unsupported mode is ever introduced. * perf(perf): cache main-thread Handler in ClipboardHistoryManager ClipboardHistoryManager is a singleton scoped to the IME service, but it was creating a fresh Handler(Looper.getMainLooper()) on every postDelayed() and on every ContentObserver registration. The main Looper is process-wide and lives for the lifetime of the app, so a single cached Handler is enough. Replace the two ad-hoc Handler allocations in registerMediaStoreObserver and in the post-paste clip restoration path with a single 'mainHandler' field on the manager. * fix(stability): use SupervisorJob in RichInputMethodManager scope The CoroutineScope backing updateShortcutIme, onSubtypeChanged and related fire-and-forget coroutines was using a plain Job. A single exception in any of those coroutines would cancel the scope and stop all subsequent subtype lookups for the lifetime of the IME process. Add SupervisorJob() so a single failure cannot tear down the rest of the lookups. * fix(stability): use ContextCompat.registerReceiver with NOT_EXPORTED flag LatinIME.onCreate was using the deprecated registerReceiver(receiver, filter) overload for the ringer mode, package add/remove and user unlocked broadcasts. On Android 13+ this throws SecurityException unless the receiver is registered with an explicit exported flag. Switch the three call sites to ContextCompat.registerReceiver with RECEIVER_NOT_EXPORTED, matching the existing style used for DICTIONARY_DUMP_INTENT_ACTION. The exported flag stays set for the NEW_DICTIONARY_INTENT_ACTION receiver, as documented in the existing comment, because the sender app may not be this one. * fix(settings): update ai provider fields dynamically Align provider preference source and observe changes dynamically to update UI fields immediately.

* fix(settings): fix and optimize gboard import
Parse Gboard format header dynamically to fix missing words and swapped values. Optimize using bulkInsert to reduce database insertion IPC overhead.
* chore: bump version to 3.8.4
Set versionCode to 3840 and versionName to 3.8.4 in build.gradle.kts. Create Fastlane changelog metadata at 3840.txt.
* feat(settings): improve text expander ui/ux
Add responsive search filtering for text expansion shortcuts. Add quick placeholder selection row with rich cursor-based insert support to Add/Edit Dialog.
* feat(settings): polish text expander guide and list
Redesign Quick Feature Guide card with styled step badges. Redesign custom shortcuts list items with premium keyword badges and chevrons. Redesign empty state with card illustration layout.
* feat(settings): clean up text expander guide
Remove redundant template placeholder explanation while retaining the list of supported placeholder tags.
* feat(settings): add more expander placeholders
Add support and UI representations for %month%, %month_short%, %year%, and %week% placeholders.
* feat(settings): add system template placeholders
Add and integrate support for %battery%, %device%, and %android% placeholders.
* feat(settings): add language placeholder
Add and integrate support for %language% placeholder, which expands to the current active keyboard display language.
* fix(perf): prevent OOM on background image decode
- Add BitmapUtils.decodeSampledBitmap() with two-pass decode and inSampleSize
- Use RGB_565 config for non-PNG images to halve memory usage
- Use BitmapFactory.decodeStream (with InputStream) instead of decodeFile
- Cap background bitmap at 2048px max dimension
- Recycle temp bitmap after validation in setBackgroundImage
Fixes: Settings.java:527, BackgroundImagePreference.kt:122
* fix(stability): replace force-unwrap !! in hot paths
- Colors.kt: use 'let' smart cast and 'error' instead of NPE on missing keyBackground
- FloatingKeyboardManager.kt: safe-call on overlayRoot, early return on null
- SuggestionStripView.kt: early return true on missing drawable
Prevents IME process crashes from null drawables/bitmaps in keyboard rendering paths.
* fix(stability): unregister SharedPreferences listener in spell-checker
AndroidSpellCheckerService.onDestroy() now unregisters the
OnSharedPreferenceChangeListener. Without this, the SharedPreferences
implementation kept a strong reference to the service, leaking it
through every spell-check session the system bound/unbound.
* fix(stability): don't call Looper.prepare() on background thread
BackupRestorePreference.kt was calling Looper.prepare() from the
ScheduledThreadPool executor, leaking a Looper per restore and posting
UI work onto an unreliable thread. Use Handler(Looper.getMainLooper())
to dispatch the FeedbackManager.message call to the UI thread.
* fix(stability): make score-limit cache update atomic in Suggest
The previous implementation had a non-atomic read-then-write of
mLastScoreLimitUpdateTime and mCachedScoreLimitForAutocorrect across
threads (suggestion lookup can happen on background threads via
SuggestionSpan / TextClassifier). Two threads could both miss the
interval check and recompute, with the second write overwriting the
first. Wrap the cache update in synchronized(this) to make the check
and update atomic.
* fix(stability): use named lock for dictionary blacklist
Three blacklist operations in DictionaryGroup used
`<outer>.apply { scope.launch { synchronized(this) { ... } } }`,
which re-bound `this` to the HashSet / CoroutineScope inside the
synchronized block. Two threads could enter the critical section
concurrently because they were locking on different objects.
Add an explicit `blacklistLock: Any` and synchronize on it.
* perf(perf): add key= to Lazy* list items for stable identity
- SearchScreen: key groups by titleRes, items by toString()
- ListPickerDialog, MultiListPickerDialog: key items by toString()
- LayoutPickerDialog: key by layout name
- ToolbarKeysCustomizer: key by enum name
- ColorThemePickerDialog: key by color name
Without keys, LazyColumn uses positional keys, causing every visible
item to be recomposed (and its remember slots discarded) on every
search keystroke or list mutation.
* perf(perf): remember() expensive computations in Composables
- SearchScreen: cache filteredItems(searchText.text) so it doesn't
re-run the search filter on every parent recomposition (only when
the search text actually changes)
- MainSettingsScreen: cache SubtypeSettings.getEnabledSubtypes() and
its joinToString() output so the description string is not rebuilt
on every recomposition
Both lists are otherwise recomputed on every pref change, every
parent state change, and every scroll-induced recomposition.
* perf(perf): avoid Paint allocation per recomposition in ColorPickerDialog
Wrap the Paint in remember { } and assign to the controller inside a
LaunchedEffect so the Paint is created once and not allocated on every
recomposition. Also avoids re-assigning the controller's wheelPaint
on every recomposition.
* perf(perf): stream logcat to file instead of buffering in memory
AboutScreen's 'Save log' was reading the entire logcat buffer into a
single String via readText(), then writing it out. For a long-running
device this can be several MB and compete with the IME process for
memory, risking OOM on low-RAM devices.
Use useLines { } to iterate line by line and write each one
directly to the output stream. The internal log is now also
streamed with a for loop and explicit toString() instead of a
joinToString() that builds the entire list as a single String.
* perf(perf): make ReorderSwitchPreference data class stable
The private KeyAndState class had var fields that were mutated in the
Switch.onCheckedChange callback, defeating Compose stability and
forcing LazyColumn items to be rebuilt on every recomposition.
- Make KeyAndState an immutable data class annotated with @immutable
- Hold the checked state in rememberSaveable(item.name) so the value
survives recomposition but is per-item
- Remove the in-place mutation of item.state in the Switch callback
- rememberSaveable the items list so it's not re-parsed on every
recomposition when the dialog is open
* fix(perf): remove top-level MutableStateFlow in AIIntegrationScreen
The previous top-level 'providerState' MutableStateFlow lived for the
process lifetime and was mutated during composition. The state can
be derived from the service on every composition (the service reads
from SharedPreferences, which is cheap).
- Replace top-level MutableStateFlow with a simple val read
- Remove the no-op updateProviderState() function
- Remove its call site in AdvancedScreen.kt
The AIIntegrationScreen will pick up provider changes on the next
composition (e.g. when the user navigates to it after changing the
provider on the AdvancedScreen).
* fix(perf): scope errorJob to the LayoutEditDialog composable
The top-level 'private var errorJob: Job?' was shared between any
two simultaneous instances of LayoutEditDialog, so opening a second
dialog would cancel the first dialog's pending error feedback job.
On configuration change the coroutine scope could be cancelled while
the top-level job reference was leaked.
Move the job into a per-composable remember { mutableStateOf<Job?>(null) }
and cancel/assign through errorJob.value.
* fix(perf): replace GlobalScope in toolbar preference listener
setToolbarButtonsActivatedStateOnPrefChange used GlobalScope.launch to
defer a UI update by 10 ms, waiting for SettingsValues to reload after
a SharedPreferences change. GlobalScope is uncancellable and its
default exception handler converts failures into silent crashes.
Replace it with a process-wide scope that uses SupervisorJob (so one
failure cannot tear down sibling preference updates) and a logging
CoroutineExceptionHandler. The function still hops to Dispatchers.Main
before touching the view tree.
* fix(perf): make SettingsNavHost navigateTo scope supervised
The CoroutineScope backing the navigateTo() helper used a plain Job,
so a single child failure would cancel the scope permanently. Add
SupervisorJob so unrelated navigation hops keep working.
* fix(stability): replace !! in colorFilter() helper
createBlendModeColorFilterCompat returns a nullable ColorFilter, but
the helper is only ever called with the supported BlendModeCompat
modes (MODULATE, SRC_IN). Replace the !! with a Kotlin error() that
throws IllegalStateException with a useful message if a new
unsupported mode is ever introduced.
* perf(perf): cache main-thread Handler in ClipboardHistoryManager
ClipboardHistoryManager is a singleton scoped to the IME service, but
it was creating a fresh Handler(Looper.getMainLooper()) on every
postDelayed() and on every ContentObserver registration. The main
Looper is process-wide and lives for the lifetime of the app, so a
single cached Handler is enough.
Replace the two ad-hoc Handler allocations in registerMediaStoreObserver
and in the post-paste clip restoration path with a single 'mainHandler'
field on the manager.
* fix(stability): use SupervisorJob in RichInputMethodManager scope
The CoroutineScope backing updateShortcutIme, onSubtypeChanged and
related fire-and-forget coroutines was using a plain Job. A single
exception in any of those coroutines would cancel the scope and stop
all subsequent subtype lookups for the lifetime of the IME process.
Add SupervisorJob() so a single failure cannot tear down the rest
of the lookups.
* fix(stability): use ContextCompat.registerReceiver with NOT_EXPORTED flag
LatinIME.onCreate was using the deprecated registerReceiver(receiver,
filter) overload for the ringer mode, package add/remove and user
unlocked broadcasts. On Android 13+ this throws SecurityException
unless the receiver is registered with an explicit exported flag.
Switch the three call sites to ContextCompat.registerReceiver with
RECEIVER_NOT_EXPORTED, matching the existing style used for
DICTIONARY_DUMP_INTENT_ACTION. The exported flag stays set for the
NEW_DICTIONARY_INTENT_ACTION receiver, as documented in the existing
comment, because the sender app may not be this one.
* fix(settings): update ai provider fields dynamically
Align provider preference source and observe changes dynamically to update UI fields immediately. Wrap preferences in key() to prevent Compose state reuse.
* feat: add standardOptimised flavor and disable r8
Add standardOptimised flavor to allow non-reproducible optimizations like R8 fullMode and baseline profiles. Turn off R8 fullMode globally to restore reproducibility for standard flavor on F-Droid. Clean APK metadata and restore global V2/V3 signing.
* perf: add baseline profile for standardOptimised
Add manual wildcard-based precompilation rules in baseline-prof.txt for standardOptimised to optimize startup, typing reaction, and suggestions. Fix dynamic property injection in settings.gradle.
* feat: remove standardOptimised package suffix
Remove applicationIdSuffix from standardOptimised product flavor to share standard package name (com.leanbitlab.leantype).

* fix: keep number row digits when keyboard is shifted
The number row layout used a shift_state_selector whose manualOrLocked
branch rendered the shifted symbol (!@#...) in place of the digit, so
engaging shift or shift-lock replaced 1234567890 with !@#$%^&*(). The
keys are now plain digit keys in every shift state, with the shifted
symbol kept as the first popup ahead of the existing fraction popups.
