Replacing the preferences object (spread reassignment) caused all consumers'
prefs references to go stale — the loop guard read the old value forever.
Svelte 5 shared state pattern requires a stable const object with property
mutations, not reassignment. Also removes duplicate theme sync $effect from
SettingsPage (already handled in +layout.svelte).
textMeasure.js, virtualList.js, and accessibilityTypography.js were
added in the 2026/04/04 session alongside VirtualSegmentList.svelte but
never committed. All four are imported from DictationPage, HistoryPage,
SettingsPage, and the viewer — a fresh clone had unresolvable imports.
textMeasure.js: pretext-backed text measurement with LRU cache.
measureTextHeight, measurePreWrap, clampTextLines, invalidateCache.
virtualList.js: binary-search visible range for variable-height virtual
lists. buildCumulativeOffsets + findVisibleRange.
accessibilityTypography.js: pretext font/line-height helpers that read
the user's accessibility preference store (Lexend / Atkinson /
OpenDyslexic mapping).
VirtualSegmentList.svelte: virtualised transcript segment renderer used
by the viewer page; depends on all three utils above.

Front-to-back QC pass turned up two independent missing-module
showstoppers (workspace did not compile; frontend did not load) plus a
handful of HANDOVER-claimed features that were wired but dead. Fixes:
P0 — gets the app booting again:
- Add the never-committed src/lib/utils/runtime.js (hasTauriRuntime
detection); 5 imports were resolving to nothing.
- Add the never-committed crates/audio/src/streaming_resample.rs
(rubato-backed StreamingResampler with new/push_samples/flush);
declared in lib.rs and used 3x by live.rs but had no impl.
- Drop the duplicate hasTauriRuntime import in routes/+layout.svelte.
- Allow the transcript-viewer window to use the default capability
(was missing from capabilities/default.json:windows, so the viewer
window could open but not invoke any Tauri command).
P1 — features documented as working but actually dead:
- Pump MicrophoneCapture::take_error_rx() into LiveStatusMessage::
Warning each loop iteration in commands/live.rs. The HANDOVER
promised cpal stream errors would surface as toasts; the channel
was created and never read.
- Replace .expect() on the WebKit media-permission setup with a
logged warning. Failure no longer aborts the whole process.
- Toast on save_preferences failure (preferences.svelte.js had a
silent console.error — now warns once per failure run via the
existing toasts store).
P2 — correctness/robustness:
- add_dictionary_entry: switch INSERT OR IGNORE to ON CONFLICT
DO UPDATE ... RETURNING id so duplicate terms get the real row id
instead of a stale auto-increment.
- search_transcripts: qualify ORDER BY fts.rank.
- InsertTranscriptParams + TranscriptRow: bump sample_rate /
audio_channels from i32 to i64 to match the Tauri DTO and avoid
silent truncation at the boundary.
- Drop the unused tauri-plugin-mcp dependency.
- Promote sqlx in src-tauri/Cargo.toml from linux-only to
unconditional (lib.rs names sqlx::SqlitePool unconditionally —
macOS/Windows builds were latently broken).
- hotkey/linux.rs: stop panicking the hotplug task on inotify
failure; degrade to "no hotplug" with a stderr warning.
- layout.svelte: store the global error/unhandledrejection handler
refs and remove them in onDestroy so HMR/window teardown doesn't
leak listeners.
Verified: cargo check -p kon-core -p kon-storage -p kon-cloud-providers
passes. cargo check on src-tauri/kon-audio/kon-hotkey requires alsa +
gtk system libs not present in this sandbox; their changes are
syntactically and type-checked against the rest of the workspace.
svelte-check requires npm install which is not available here.

CROSS-PLATFORM AUDIT:
- Linux x86_64 (Fedora 43, KDE Wayland): HIGH confidence (the dev target)
- Linux other distros / X11: MEDIUM (tested patterns, untested distros)
- Windows 10/11: LOW — theoretically supported via Tauri + CPAL + whisper.cpp
+ tauri-plugin-global-shortcut (the custom evdev hotkey is no-op on
Windows); has had zero hands-on testing
- macOS Apple Silicon / Intel: LOW — same; macOS Info.plist needs
NSMicrophoneUsageDescription for the bundled app, and the path bug
fixed in this commit
REAL BUG FIXED — macOS app_data_dir was Unix-style:
crates/storage/src/file_storage.rs::app_data_dir() previously fell into
the "Unix" branch on macOS and wrote to ~/.kon/, which violates Apple
guidelines and confuses install/uninstall tooling. Now correctly:
- Windows: %LOCALAPPDATA%/kon (unchanged)
- macOS: ~/Library/Application Support/Kon/
- Linux: $XDG_DATA_HOME/kon or ~/.local/share/kon (XDG Base Directory),
with legacy ~/.kon/ fallback so existing installs keep working
- Other Unix: ~/.kon/ (unchanged)
OS DETECTION LAYER:
- New get_os_info Tauri command in commands/diagnostics.rs returns:
{os, arch, family, usesCmd, isWayland, customHotkeyBackend,
primaryModifierLabel}
- New src/lib/utils/osInfo.js helper:
- async loadOsInfo() warms a cache, called once at root layout mount
- then isMac() / isWindows() / isLinux() / modKeyLabel() / isWayland()
are synchronous
- browser-preview fallback reads navigator.platform
- Lets components localise hotkey labels (Cmd vs Ctrl), file-picker
copy ("Open Finder" vs "Open Explorer"), etc, without recomputing in
every place.
cargo check -p kon-storage clean. Updated HANDOVER-2026-04-17.md with
a per-platform confidence table.
THE BRIEF:
For the friends beta we need verbal feedback AND technical feedback —
some bugs the user cannot describe but a stack trace can. Built it in
two layers, with Layer 3 deferred until there is real volume.
PRIVACY POSTURE (matches Kon's local-first positioning):
- All capture is to disk only. Nothing is transmitted.
- The manual report bundler shows the user exactly what would be
shared and lets them choose to copy / save it.
- No remote endpoint, no Sentry, no opt-out telemetry.
LAYER 1 — Always-on local capture:
- Rust panic hook (commands/diagnostics.rs::install_panic_hook) writes
each panic to ~/.kon/crashes/<unix-ts>-<short-id>.crash. Captures
thread name, OS/arch, RUST_BACKTRACE state, and the panic info.
Installed before tauri::Builder so it catches setup-time panics too.
- Frontend window.onerror + window.unhandledrejection in
src/routes/+layout.svelte forward to the new log_frontend_error
Tauri command, which inserts into the existing error_log SQLite
table. Best-effort: errors in the error handler itself are swallowed
so logging can never crash the app.
- Existing error_log table (migration v1) is now actually used —
closes the TODO from crates/storage/src/database.rs:409.
LAYER 2 — Manual diagnostic report:
- Settings → About → Diagnostics section: Generate report → Preview →
Copy / Save.
- Report is plain markdown so it pastes cleanly into email, Discord,
GitHub issues. Sections: app version + OS, sanitised settings JSON,
recent error_log rows, last 5 crash dumps with previews, log file
tail (8KB).
- Preview is shown in a <details> with the full text the user can
inspect before deciding to share.
- Save writes to ~/.kon/diagnostic-reports/kon-diagnostic-<ts>.md.
NEW FILES:
- src-tauri/src/commands/diagnostics.rs (panic hook + 5 Tauri commands)
CHANGES:
- crates/storage/src/file_storage.rs: crashes_dir() + logs_dir() helpers
- crates/storage/src/database.rs: ErrorLogRow + list_recent_errors()
- crates/storage/src/lib.rs: re-exports
- src-tauri/src/commands/mod.rs: + diagnostics module
- src-tauri/src/lib.rs: install_panic_hook() before Builder; 5 new
Tauri commands registered (log_frontend_error,
list_recent_errors_command, list_crash_files,
generate_diagnostic_report, save_diagnostic_report)
- src/routes/+layout.svelte: installGlobalErrorCapture() at mount
- src/lib/pages/SettingsPage.svelte: diagnostic state + buttons +
preview block at the end of the About section
cargo check -p kon-storage clean. Settings.svelte if/each balanced.
LAYER 3 (deferred):
- Optional opt-in remote reporting (self-hosted Sentry on Tartarus or
similar). Not for friends beta. Open up after volume justifies it.
VOCABULARY PANEL (Day 5):
src/lib/pages/SettingsPage.svelte gains a new collapsible "Vocabulary"
section between Audio and Transcription. Wires the dictionary commands
shipped in 1cce567:
- list_dictionary_command on mount + onfocus refresh
- add_dictionary_entry_command (term + optional note)
- delete_dictionary_entry_command
- Inline error feedback via vocabularyError
- Empty-state copy + per-entry remove button with aria-label
The dictionary terms are intended to be injected into the LLM cleanup
prompt so the model preserves user-specific vocabulary (medication
names, place names, jargon, names of people in the user's support
network — particularly important for the ND audience). The LLM client
itself is currently a stub (crates/ai-formatting/src/llm_client.rs);
when it lands, it can import list_dictionary from kon_storage and
inject terms into the prompt suffix.
WAYLAND SELF-RELAUNCH (Day 6):
src-tauri/src/lib.rs gains ensure_x11_on_wayland() which runs before
tauri::Builder. On Linux Wayland sessions (XDG_SESSION_TYPE=wayland) it
sets GDK_BACKEND=x11, WINIT_UNIX_BACKEND=x11, and
WEBKIT_DISABLE_DMABUF_RENDERER=1 — the env vars HANDOVER.md documents
the user manually prefixing.
Drops the "users have to remember the env-var prefix" friction.
Idempotent: existing values are respected. Inspired by Open-Whispr's
Chromium --ozone-platform=x11 self-relaunch.
Compile-checked: cargo check -p kon-storage clean. Settings.svelte
$state / #if balanced (28 state, 34/34 if/endif).
NEXT: Phase 6 — dogfooding readiness doc with Jake test instructions.
addToHistory, renameHistoryEntry, deleteFromHistory in
src/lib/stores/page.svelte.js now dual-write to:
- the in-memory `history` array (UI snappiness, unchanged)
- localStorage (offline / browser-preview fallback, unchanged)
- SQLite via the new Tauri commands from 1cce567 (the canonical store)
The SQLite write is best-effort: failure does not lose the in-memory
copy. Console-warns for diagnostic visibility. Browser-preview path
correctly skips the Tauri call.
HistoryPage rename flow (renameItem) now calls renameHistoryEntry, which
goes through update_transcript. Closes the long-standing TODO from
architecture-review.md §13: rename was UI-only, never persisted, lost
on reload.
On rename failure a warn-toast surfaces "your change is visible now but
did not save" so the user is not surprised on next launch.
NOT WIRED YET (deferred):
- HistoryPage.searchQuery still filters in-memory rather than calling
search_transcripts. Fine for small histories; FTS5 infrastructure is
in place to upgrade when needed.
- Reading initial history from SQLite on session boot. localStorage
remains the cold-start source for now; SQLite catches up via dual-
write. A backfill / one-time sync command can land later.
THE PROBLEM (Codex review + architecture-review.md §1, §14):
Multiple critical paths discard errors silently — `let _ = insert_transcript(...)`,
`.catch(() => {})`, inline `error = ...` state that not every page surfaces. ND
users in particular need explicit feedback when something fails; silent
failure is worse than no feature.
SHIPPED:
src/lib/stores/toasts.svelte.js (new):
- Minimal in-house toast store (~80 lines, no svelte-french-toast dep)
- Severity → palette: info/success → moss, warn → signal, error → ember
- Auto-dismiss durations per severity (success 3s, info 4s, warn 6s,
error sticky)
- `invokeWithToast(invoke, command, args, errorTitle?)` helper wraps a
Tauri invoke and toasts on failure while still throwing for callers
that need to handle the error themselves
src/lib/components/ToastViewport.svelte (new):
- Reads from the toasts store
- Bottom-right stack, max-width clamp on small screens
- aria-live=polite + role=alert on error toasts (screen-reader friendly)
- Slide-in animation honours `html.reduce-motion` for the existing
preferences toggle
- Severity left-border in brand colours via existing CSS variables
src/routes/+layout.svelte:
- Mounts <ToastViewport /> once at the app root so toasts work from any
page or window
src/lib/pages/DictationPage.svelte:
- First error-toast wiring: failures starting recording now show a
sticky toast in addition to the inline `error` panel
- Replaces a previously easy-to-miss failure-mode
NEXT (Day 4 batch):
- Wire toasts into FilesPage, HistoryPage, SettingsPage, ModelDownloader
(all currently swallow errors)
- Add `add_transcript`, `list_transcripts`, `update_transcript` (closes the
long-standing TODO Codex flagged), `delete_transcript` Tauri commands
wrapping the existing storage layer
- Switch addToHistory to dual-write (localStorage + SQLite) so the
canonical store catches up with the actual transcript flow
- FTS5 transcripts_fts virtual table + search command
- Wrap multi-row writes (decompose_and_store) in DB transactions
Day 1 follow-up to 96980c7. The device-picker UI in Settings now
actually takes effect: settings.microphoneDevice flows from the Svelte
store, through the Tauri invoke, into MicrophoneCapture::start_with_device
on the Rust side.
Touched paths (back-to-front):
- src-tauri/src/commands/audio.rs:start_native_capture — new optional
`device_name: Option<String>` parameter; routes to start_with_device
when set, falls back to auto-select start() when None or empty.
- src-tauri/src/commands/live.rs:StartLiveTranscriptionConfig — new
optional `microphone_device: Option<String>` field with same
semantics (rename_all = "camelCase" maps it to microphoneDevice on
the wire).
- src-tauri/src/commands/live.rs:run_live_session — picks
start_with_device when an explicit name is provided.
- src/lib/pages/DictationPage.svelte — passes
microphoneDevice: settings.microphoneDevice || null in the invoke.
Behaviour:
- "Auto" in the picker (empty string) -> backend auto-selects, skipping
monitor sources and validating by RMS energy.
- Specific device -> backend opens that device by exact name; if it has
been disconnected the user gets a clear error pointing them back at
Settings.
cargo check -p kon-audio passes clean. Tauri-crate cargo check requires
cmake (pre-existing infra dependency for whisper-rs-sys); install via
`sudo dnf install cmake clang-devel`.
Day 1 of the upgrade plan (output/reports/kon-upgrade-plan-2026-04-17.md
in the CORBEL workspace). Fixes the HANDOVER.md blocker: native live
transcription was capturing silence because PulseAudio/PipeWire monitor
sources (speaker loopback) were winning the device-selection race —
they deliver zero-valued bytes that satisfied the original
"any device that produces data within 350ms" check.
WHAT CHANGED:
crates/audio/src/capture.rs (rewrite):
- New `DeviceInfo` struct (serde-derived) for the Settings device picker
- New `MicrophoneCapture::list_devices()` enumerates inputs with metadata
- New `MicrophoneCapture::start_with_device(name)` for explicit selection
- Refactored `start()` with monitor-source filtering by name pattern
(.monitor suffix, "Monitor of " prefix, "loopback" substring) and
RMS-energy validation in a 350ms window
- Two-pass selection: real inputs first, monitor sources only as
last-resort fallback with explicit warning log
- Drop counter (Arc<AtomicU64>) tracks chunks dropped by `try_send`
failure under load — Codex review caught this as a silent-failure risk
- `dropped_chunks()` accessor for the live session
- Verbose tracing at every step for diagnosis
- Unit test for monitor-name detection
- `cargo check -p kon-audio` passes clean
crates/audio/src/lib.rs:
- Re-export `DeviceInfo`
crates/audio/Cargo.toml:
- Add serde dependency (for DeviceInfo derives)
src-tauri/src/commands/audio.rs:
- New `list_audio_devices` Tauri command (returns Vec<DeviceInfo>)
src-tauri/src/lib.rs:
- Register `list_audio_devices` in invoke_handler
src/lib/pages/SettingsPage.svelte:
- New "Audio" section with microphone picker dropdown
- Auto-populates on mount via `list_audio_devices`
- Refresh button + clear messaging about monitor sources
- Likely-monitor entries marked disabled in the dropdown
- Auto mode is the default (empty string in settings.microphoneDevice)
src/lib/stores/page.svelte.js:
- New `microphoneDevice` field in defaults (empty = auto-select)
NEXT STEPS (per the upgrade plan):
- Wire `microphoneDevice` from settings into `MicrophoneCapture::start_with_device`
in the live and standalone capture paths (currently both still call
the auto-selecting `start()`)
- Test on real hardware (Wayland + multiple input devices)
- Codex sanity-check of this diff is running in parallel; addendum to
follow if anything substantive comes back

prevTaskIds was declared as $state, causing the $effect that writes to
it to re-trigger itself infinitely (effect_update_depth_exceeded). The
variable is just a comparison reference — doesn't need to be reactive.
Changed to a plain let.
Also removed debug event loggers and reverted grain z-index.

The invisible z-40 overlay was still eating pointer events across the
main content. Removed the backdrop — sidebar now floats without blocking
anything. Close with Escape key.

The full-screen backdrop (fixed inset-0 z-40) was eating all pointer
events, making the app unusable when the task sidebar was open. Replace
with a backdrop that only covers the content area (not titlebar) and
sits beside the sidebar rather than wrapping it.

Add kon-hotkey crate with evdev-based global hotkey capture that works on
Wayland (and X11). Patterns from whisper-overlay: per-device async listeners,
inotify hotplug with udev permission retry, watch channel for live config
updates. Frontend detects Wayland at startup and selects evdev or
tauri-plugin-global-shortcut automatically.
Model downloads now support HTTP Range resume for interrupted downloads and
optional SHA256 integrity verification (incremental, no second pass).

- Consolidated 7 separate Card components into a single Card with 8 accordion sections
- Added openSection $state variable; 'transcription' open by default, others collapsed
- Each section header is a clickable button with +/− indicator; clicking open section closes it
- Section headings use font-display italic 18px (vs 26px page title) as accordion headers
- All existing functionality preserved: toggles, dropdowns, model download/load, profiles, templates, hotkey recorder, output folder picker
- Profiles & Templates remain as nested accordion-within-accordion (existing pattern kept)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Replaced tall header (pt-6 pb-4 with 28px timer + label stack) with 56px control strip
- Control strip: 40px record button + waveform placeholder + 20px timer + status badge + task toggle
- Waveform placeholder shows animated bars during recording, hint text at idle
- Actions moved to dedicated toolbar row (justify-end) below control strip
- Status footer (word count, format mode, profile) moved inside transcript Card
- Insert-at-cursor indicator relocated to status footer
- Page container remains flex-col h-full; transcript area fills all remaining space
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Replace card-per-entry layout with single-line rows (title truncated, duration, source icon, date, chevron)
- Add expand/collapse per row via expandedId $state (id-based, one at a time)
- Expanded detail shows full transcript, audio player (when active), and action buttons (Rename, Copy, Open viewer, Delete)
- All existing functionality preserved: search, playback, rename, delete, openViewer, clearAll
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Add sidebarCollapsed to settings defaults (persists via localStorage on saveSettings)
- Sidebar collapses to 48px icons-only view with smooth 200ms transition
- Toggle button (chevron) at top of nav; [ keyboard shortcut in layout (input-safe)
- Auto-collapse on window resize below 900px (checked on mount and on resize event)
- Titlebar left spacer tracks sidebar width reactively (48px / 210px)
- All labels, profile selector, status text hidden in collapsed mode; nav items show tooltips via title attribute
