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.
Finally exposes the canonical SQLite store to the frontend. Previously
the transcript/task tables existed but no Tauri command read or wrote
them — the UI lived entirely in localStorage. Closes that gap and adds
the missing commands flagged by both Codex and architecture-review.md
§13.
MIGRATIONS:
- v2 adds:
- transcripts_fts virtual table (FTS5, porter+unicode61 tokeniser,
diacritics-folded) backed by transcripts via content_rowid
- INSERT/UPDATE/DELETE triggers keep FTS in sync automatically
- dictionary table for custom vocabulary (term, note, created_at)
- Append-only as required; never modifies v1
STORAGE FUNCTIONS (crates/storage/src/database.rs):
- list_transcripts_paged(limit, offset) — pagination
- count_transcripts() — for "showing X of N" in UI
- update_transcript(id, text?, title?) — closes the historic
architecture-review.md §13 rename-never-persists TODO
- search_transcripts(query, limit) — FTS5 wrapper
- list_dictionary / add_dictionary_entry / delete_dictionary_entry
- DictionaryEntry struct exported
TAURI COMMANDS (src-tauri/src/commands/transcripts.rs new file):
- add_transcript, list_transcripts, count_transcripts_command,
get_transcript, update_transcript, delete_transcript,
search_transcripts
- list_dictionary_command, add_dictionary_entry_command,
delete_dictionary_entry_command
- TranscriptDto + DictionaryDto for camelCase frontend serialisation
REGISTRATION (src-tauri/src/lib.rs):
- All 10 new commands wired into the invoke_handler
cargo check -p kon-storage passes clean. The Tauri crate cargo check
still requires `sudo dnf install cmake clang-devel` for whisper-rs-sys
(pre-existing infra dep, unrelated to this work).
NEXT (still in this sprint):
- Wire DictationPage / FilesPage to call add_transcript on every save
(dual-write: keep localStorage for now, add SQLite alongside)
- Wire HistoryPage rename to call update_transcript (fixes the TODO)
- Add a History search input that calls search_transcripts
- Add Settings → Dictionary panel
- Inject dictionary terms into the LLM cleanup prompt
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
Closes the 6 Codex review findings on the Day 1 mic-capture work
(commits 96980c7 + 41db162). Detail in
output/reports/kon-codex-mic-capture-followup-2026-04-17.md (CORBEL
workspace).
src-tauri/src/commands/audio.rs:
- D1: Sending an explicit stop signal before dropping stop_tx, so the
accumulator task wakes up immediately rather than waiting for the
Disconnected detection added below.
- D2: Wrapping MicrophoneCapture::start() in tokio::task::spawn_blocking.
start() can spend up to 350ms × N_devices × 2 passes; running it on
the async runtime froze other Tauri commands.
- M3: Match on rx.try_recv() error variants. Empty -> sleep + continue.
Disconnected -> exit accumulator task immediately. Previous behaviour
was an infinite loop after the capture stream died.
crates/audio/src/capture.rs:
- D3: Added DEAD_SILENCE_FLOOR (1e-7) gate that applies even in the
fallback pass. PulseAudio/PipeWire can stream zero-valued bytes from
a borked device; that is worse than failing fast.
- M1: Validation requeue (`for chunk in collected { try_send }`) now
counts drops in the same dropped_chunks counter.
- M2: New CaptureRuntimeError type. The cpal stream error callback now
forwards errors via a separate sync_channel (capacity 16) that the
live session can drain via take_error_rx() and surface as toasts.
Re-exported from kon_audio crate root.
cargo check -p kon-audio passes clean.
NOT YET DONE (M4): JACK-specific monitor name patterns. Defers until
testing on a JACK host. Current is_monitor_name() may miss JACK
conventions.
Wiring the new error_rx into the live session and surfacing as toasts
lands with the Day 3 error-toast system commit.
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.

The CTC model (onnx-community/parakeet-ctc-0.6b-ONNX) only has an encoder
— no decoder_joint or nemo128 preprocessor. transcribe-rs expects a TDT
transducer variant with all three. Switch to istupakov/parakeet-tdt-0.6b-v2-onnx
which has the correct int8 files.

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
