* fix: add SHA256 verification to prevent corrupt partial download loop
Fixes issue #858 — corrupt .partial files caused an infinite loop where
a failed/cancelled download would resume from EOF, pass extraction, and
loop forever with no way to recover without manual file deletion.
Three-part fix:
- Add sha2 crate and compute_sha256() helper; verify hash post-download
before extraction/rename for all 15 built-in models. Hash mismatch
deletes the .partial so the next attempt starts fresh.
- Delete .partial on extraction failure (independent of checksums) so
corrupt archives can't re-enter the loop via the same path.
- Emit model-download-failed event from the command handler so all
callers (ModelsSettings, Onboarding) get consistent error feedback
via a central store listener rather than per-caller return-value checks.
SHA256 hashes hardcoded alongside each model's URL in ModelInfo.
Custom models (sha256: None) skip verification silently.
* chore: remove doc comment from sha256 field
Doc comments on exported specta types propagate into bindings.ts as
inline JSDoc — not useful in generated TS. Removing at the source.
* test: add SHA256 verification unit tests
Extracts inline verify logic into ModelManager::verify_sha256() and
covers all four branches:
- None expected hash → skipped (custom models)
- Matching hash → ok, file kept
- Mismatched hash → error returned, partial file deleted
- Unreadable file → error returned
Ensures corrupt partial downloads are always cleaned up so the next
attempt starts fresh.
* chore: cargo fmt
* fix: clear cancel flag on sha256 failure, spawn_blocking for hash, fallback cleanup
- remove cancel_flags entry on sha256 failure to prevent a stale flag
from immediately cancelling the next retry attempt (HIGH)
- add fallback state cleanup in modelStore when result.status != ok,
so spinner clears even if model-download-failed event is missed (HIGH)
- run compute_sha256 in spawn_blocking to avoid stalling the async
executor while hashing large model files (up to 1.6 GB) (MEDIUM)
* emit some more events for the ui to pick up
* add translations + format

* feat(audio): opt-in lazy stream close for bluetooth mic latency
keep the microphone stream open for 30s after recording stops to
reduce latency on back-to-back transcriptions. gated behind an
experimental setting (off by default) since it keeps the mic actively
capturing while idle — degrading bluetooth audio quality on macOS.
adds lazy_stream_close setting, tauri command, toggle in experimental
settings section, and i18n strings.
* fix: gate lazy close on setting in cancel_recording path
cancel_recording was unconditionally calling schedule_lazy_close,
keeping the mic open for 30s even when the setting was disabled.
also bump close_generation on AlwaysOn→OnDemand switch to cancel
any stale lazy close timers.

* refactor: migrate transcribe-rs from v0.2.8 to v0.3.0
Breaking API migration:
- engines::* → onnx::* module paths, whisper_cpp::* for Whisper
- TranscriptionEngine trait → SpeechModel trait
- Two-step new()+load_model() → one-step Model::load()
- transcribe_samples(Vec<f32>) → transcribe(&[f32])
- Explicit unload_model() → RAII drop
- Canary engine now from transcribe-rs instead of local crate
Removes canary-engine local crate dependency.
Uses path dependency to local transcribe-rs clone (temporary).

* ci: add temporary test workflow for portable ZIP validation
* ci: fix mock setup in test workflow
* ci: remove temporary test workflow
* feat: add portable mode option to NSIS installer
Custom NSIS template based on tauri-v2.9.1 upstream with 6 targeted
modifications for portable mode support:
- New PortableMode variable and /PORTABLE CLI flag for silent installs
- Install type selection page with Normal/Portable radio buttons
- Conditional default directory (Desktop for portable, LocalAppData for normal)
- Skip registry writes, file associations, deep links, and uninstaller for portable
- Skip Start Menu and desktop shortcuts for portable installs
- Create portable marker file and Data/ directory on portable install
The existing portable.rs runtime detection is unchanged — it looks for the
same marker file this installer creates.
Usage:
GUI: select "Portable Installation" on the install type page
Silent: Handy_setup.exe /S /PORTABLE /D=C:\path\to\Handy
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat: implement true portable mode via source code path override
Detect a `portable` marker file next to the executable at startup.
When present, redirect all data paths (settings, models, recordings,
database, logs) to a local `Data/` directory instead of %APPDATA%.
This approach works because it intercepts path resolution at the Rust
level, bypassing Tauri/Windows Shell API limitations that made the
previous environment-variable and junction approaches unreliable.
Changes:
- Add src-tauri/src/portable.rs with OnceLock-based detection
- Replace all app.path().app_data_dir() calls with portable helper
- Configure tauri-plugin-log to use Folder target when portable
- Configure tauri-plugin-store with absolute path when portable
- Simplify build.yml portable ZIP (exe + resources + marker file)

* fix: add missing Manager trait import in portable.rs

* fix: redirect WebView2 cache to portable Data dir
Move main window creation from tauri.conf.json to setup closure so
we can set data_directory when in portable mode. This prevents
WebView2 from creating %LOCALAPPDATA%\com.pais.handy.
Also set data_directory on the recording overlay window.

* fix: auto-detect portable mode during updates
When the Tauri updater runs the installer with /UPDATE, the install type
page is skipped and /PORTABLE is not passed. Detect the existing portable
marker file in .onInit so updates preserve portable mode automatically.

* feat(models): auto-discover custom Whisper models in models directory
Enable automatic discovery of custom GGML-format Whisper models (.bin files)
placed in the models directory, so users don't need to modify source code
to use their own fine-tuned models.
Backend changes:
- Add discover_custom_whisper_models() to scan for .bin files
- Generate display names from filenames (e.g., "my-model" → "My Model")
- Skip predefined model filenames to avoid duplicates
- Add 3 unit tests for discovery logic
Frontend changes:
- Split model dropdown into 3 sections: Custom, Downloaded, Downloadable
- Add collapsible section for downloadable models to reduce clutter
- Add max-height with scroll for long model lists
- Add "Custom" badge for user-provided models
* feat(models): make custom Whisper model discovery opt-in
[why] Address maintainer concern about support burden from community
models. Custom models should be a power-user feature, not enabled by
default.
[how] Add custom_models_enabled setting (default: false) in Debug
settings. Discovery only runs when enabled. Models show "Not officially
supported" messaging. Documentation updated with enable steps.
* feat(models): add is_custom field and integrate custom models with new UI
[why]
PR review requested an explicit is_custom field instead of inferring
custom status from url === null. Custom models also need proper
integration with the new models settings page from PR #478.
[how]
- Add is_custom: bool to ModelInfo struct, set true on discovered models
- Change discover_custom_whisper_models signature from &PathBuf to &Path
- Use 0.0 sentinel scores so UI hides score bars for custom models
- Add "Custom Models" section to ModelsSettings with 3-way model split
- Show "Custom" badge in ModelCard and ModelDropdown
- Hide language/translation tags when supported_languages is empty
- Remove custom models from available_models on delete instead of
just marking as not downloaded (they have no re-download URL)
- Update tests with new fields and assertions
* chore(i18n): add custom model translation keys to all locales
[why]
Custom model feature introduces 5 new translation keys that need
to be present in all 15 non-English locales for CI to pass.
[how]
Add English placeholder values for: customModelDescription,
modelSelector.custom, settings.models.customModels,
settings.debug.customModels.label, settings.debug.customModels.description
* fix(models): keep language filter visible when no models match
[why]
The language filter was inside a conditionally rendered section
that disappeared when no downloaded models matched the selected
language, leaving the user stuck with no way to change the filter.
[how]
Always render the "Your Models" header row with the language filter,
only conditionally render the model cards below it.
* docs: fix custom models section reference in README
Model selector → Models settings page.
* fix(models): apply custom models toggle immediately without restart
[why]
Two bugs reported in PR review: (1) app breaks on restart when a
custom model was selected and the toggle is disabled — selected_model
still points to the missing model, causing "Model not found" error.
(2) Custom models remain visible in the UI after toggle-off because
the in-memory model list is never updated and no event is emitted.
[how]
- Add remove_custom_models() and add_custom_models() to ModelManager
for runtime mutation of the available_models mutex
- On disable: reset selected_model to empty if it's a custom model,
then remove custom models from the in-memory list
- On enable: run discover_custom_whisper_models against the mutex
- Emit model-state-changed event so the frontend refreshes immediately
* chore(i18n): remove "restart required" from custom model descriptions
Toggle now takes effect immediately, so the restart sentence
is inaccurate. Updated all 16 locales and README instructions.
* fix(models): clear stale model selection on startup
[why]
If a custom model file is deleted from disk while it's the selected
model, the app gets stuck on "Loading..." forever on next launch
because the model ID is not in available_models but
auto_select_model_if_needed only checked for empty string.
[how]
Validate that selected_model exists in available_models before
accepting it. If not found, clear the selection so auto-select
picks a valid downloaded model.

* feat: add models settings page with filtering and management
- add dedicated models settings page in sidebar
- reuse ModelCard component from onboarding for consistent UI
- add filter buttons for all/multi-language/translation models
- add model deletion with native confirmation dialog (tauri-plugin-dialog)
- consolidate model event listeners into useModels hook (Zustand store)
- remove duplicate event listeners from ModelSelector, LanguageSelector, TranslateToEnglish
- gate AccessibilityPermissions to macOS only
- add is_recommended field to model registry for featured models
- remove unused get_recommended_first_model command
- add translations for all 9 supported languages
* feat: add language filter to models settings page
adds a searchable language dropdown filter to the models page that lets users filter models by language support. when a non-english language is selected, models that don't support multiple languages (like parakeet) are hidden.
- add searchable language dropdown (right-aligned in filter row)
- filter models using supports_language_selection capability
- add allLanguages translation key to all 10 locales
* feat: add translation consistency checker script
- add scripts/check-translations.cjs to validate all language files
- script dynamically discovers languages from directory structure
- checks that all languages have same keys as english reference
- detects missing and extra keys in each language
- add check:translations npm script
- integrate into github actions lint workflow
- validates translations on every pull request
* fix: update imports and add missing translations after rebase
- replace useModels hook with useModelStore in components
- add permission error keys to all languages
- add model settings keys to cs and tr (new languages from main)
* fix: translate english placeholders in cs and tr locale files
* refactor: simplify model dropdown and migrate store to immer
- model dropdown now only shows downloaded models (no download/delete)
- convert store to immer with record types for immutability
- remove unused translation keys (welcome, downloadPrompt, etc.)
- add missing moonshine-base model fields
- sync translations after rebase
* fix: add download cancellation support and ui improvements
- add full download cancellation with Arc<AtomicBool> flags in rust backend
- add progress event throttling (100ms) to prevent ui freeze
- add cancel button to model card in settings page
- add model-deleted event listener to refresh dropdown after deletion
- remove pink background from recommended models in settings (keep badge only)
- add cancel/cancelDownload translation keys to all 14 languages
* fix: remove duplicate language/translate settings from general and advanced
settings are now only in ModelSettingsCard, not duplicated in their old locations
* fix: prevent model dropdown from being clipped by window edge
* add languages explicitly, clean up some ui
* fix: clear bottom progress bar when download is cancelled
The ModelSelector component maintains its own local state for download
progress. When a download was cancelled, the Rust backend would update
its state but never emitted an event to notify the frontend. This caused
the bottom progress bar to remain stuck showing "Downloading X%".
Added model-download-cancelled event emission in Rust and corresponding
listener in ModelSelector to clear progress state on cancellation.
* fix: align model card content to top to prevent floating elements
Changed ModelCard flex alignment from items-center to items-start so
the accuracy/speed bars stay at the top when the card expands (e.g.,
during download with progress bar visible).
* fix: prevent model deletion from interrupting active extractions
Added extracting_models HashSet to track models currently being
extracted. The update_download_status() function now skips cleanup
of .extracting directories for models that are actively extracting,
preventing a race condition where deleting one model would interrupt
another model's extraction process.
* refactor: migrate ModelCard buttons to Button component
Added two new Button variants for common patterns:
- primary-soft: soft/tinted primary buttons (used for download)
- danger-ghost: subtle destructive actions (used for delete/cancel)
Migrated all hardcoded buttons in ModelCard to use the shared Button
component for consistency and maintainability.
* feat: separate downloaded and available models into sections
Split the models list into "Your Models" and "Available to Download"
sections for clearer visual distinction between downloaded and
downloadable models.
Also adds missing translation keys to all locales:
- modelSelector.capabilities.singleLanguage
- modelSelector.capabilities.languageOnly
- settings.models.yourModels
- settings.models.availableModels
* fix: add missing translations after rebase onto main
add post-processing hotkey translations to all 15 locales and
backfill 29 missing keys for korean locale added in main.
* fix: add label to model delete button for clearer destructive state
* check translations as typescript
* format
* better text for dropdown
* wip ui tweaks
* rounded + ui tweaks
* fix download not 0% immediately, ui tweaks
* tweak name
