Without this, every secondary window (preview overlay, task float,
transcript viewer) opened at whatever spot Tauri / the compositor picked,
which was especially noticeable on Wayland where placement hints are
advisory. Main window's position was also lost on restart.
Registering tauri_plugin_window_state in the builder gives automatic
per-window-label save + restore. State lives in app-data/window-state.json;
fresh installs still fall back to the builder defaults (no changes to
inner_size on any of the four windows). Covers OpenWhispr issue #605 and
the broader UX pain.
No frontend changes — the plugin is purely backend. Regenerated ACL
manifests / desktop + linux schemas pick up the plugin registration.

KWin reads _NET_WM_STATE_SKIP_TASKBAR for its Alt+Tab list, which OW-2
already wired via skip_taskbar(true) on the builder. On Hyprland, Sway,
and GNOME Mutter that's not always enough — some switchers still enumerate
the overlay. Classifying the window as gdk::WindowTypeHint::Utility signals
to the compositor that this is an assistive auxiliary surface, so switchers
and auto-tilers leave it alone. No behavioural change on KWin.
GTK3 only honours the type hint before the window maps, so the preview
builder now starts .visible(false); we grab the gtk_window() via Tauri's
escape hatch, set the hint, then show(). The existing hide/show on
re-open still works — hint is a property of the gtk::ApplicationWindow
and survives the cycle.
Added gtk = "0.18" and gdk = "0.18" as Linux-only deps. Both are already
pulled in transitively via webkit2gtk 2.0, so this is just surfacing them
by name — no new compile cost.

Without _NET_WM_STATE_STICKY the preview overlay only renders on whichever
virtual desktop it opened on — switch desktops mid-dictation and the raw
transcription stream vanishes exactly when you need it (the whole point of
the overlay is that you're working in another app).
visible_on_all_workspaces(true) on the WebviewWindowBuilder sets STICKY via
GTK on X11/XWayland, which KWin + Mutter both honour. Combined with the
existing skip_taskbar(true) — KWin's default Alt+Tab list already respects
_NET_WM_STATE_SKIP_TASKBAR — the preview now behaves like the assistive
overlay it's meant to be: follows you, out of the way of window switchers.
Applied only to the preview window. Task-float and transcript-viewer are
primary surfaces that should stay on their own desktop, so they keep the
current behaviour.
Follow-up if dogfooding shows Alt+Tab clutter on non-KDE compositors: layer
a GTK WindowTypeHint::Utility via with_webview. Not needed for KWin.
Matches OpenWhispr's PR #183 shape for KDE Plasma.

Phase H landed the transcription preview overlay. Phase C landed auto-paste.
With both enabled the combo is broken on Wayland compositors (KWin, Mutter):
the overlay is always_on_top + visible at the moment paste_text fires its
Ctrl+V keystroke, and the compositor resolves the key to the topmost visible
window — which is the overlay, even though we built it with focused=false.
Net result: the transcript pastes into Kon instead of whatever app the user
was actually dictating into.
Fix, mirroring OpenWhispr's PR #246 shape: before trigger_paste_keystroke,
hide the transcription-preview window if it exists and is visible, then
sleep PREVIEW_HIDE_SETTLE_MS (80ms) so the compositor recomputes focus onto
the previously-focused app. No reshow — the user's confirmation is the text
appearing in the target app, not a fading overlay. The 80ms is enough on
KWin and Mutter; tunable if it shows up differently on other compositors.
paste_text now takes the tauri::AppHandle so it can reach the preview
window. Frontend invocation signature is unchanged (Tauri injects the
handle; the JS call site still passes { text }).

Ported the best bits of OpenWhispr's TranscriptionPreviewOverlay into Kon's
window conventions. Off by default — toggle in Settings → Output → "Floating
preview when Kon is unfocused". Opens only when the main window isn't
focused at the start of a recording, so it never adds noise when the user
can already see the transcript in the main surface.
Phase state machine (src/routes/preview/+page.svelte):
- listening — pulsing dot, no text yet
- live — animated bars + streaming raw Whisper output
- cleanup — accent bars while the LLM cleanup pass runs
- final — checkmark + formatted text + 4s auto-hide
Data plumbing: raw segment text is captured before post_process_segments in
live.rs (new raw_text field on LiveResultMessage) and in transcription.rs
(new raw_text in the transcription-result payload). DictationPage forwards
raw_text to the overlay via Tauri global events — preview-listening on
start, preview-append per chunk, preview-cleanup before the LLM pass,
preview-final with the formatted text, preview-hide when a run produced no
transcript (empty recording / cancel).
Window is always_on_top, skip_taskbar, focused=false so it never steals
focus from whatever the user is dictating into. open_preview_window shows
an existing hidden preview or builds it fresh; close_preview_window hides
without destroying so the next open is instant.

Default off. When on, the layout polls detect_meeting_processes every 15s
with the user's app-name patterns. On a fresh match (edge-triggered — no
re-toast until the app goes away and comes back) we fire a reminder toast
that tells the user which meeting app appeared and their global hotkey. We
never start recording on this signal; the ideology rule says the user
decides. The signal is a single channel: process list match only — no mic
activity heuristic, no calendar.
Backend adds kon_core::process_watch::{list_running_process_names,
match_meeting_patterns} over sysinfo, exposed to the frontend as the
detect_meeting_processes Tauri command.
Settings ships two new fields — meetingAutoCapture (bool) and
meetingAutoCaptureApps (string[]) — with a comma-separated input in the
Output section. Default app list is ["zoom", "teams"], user-editable.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds an opt-in "auto-paste into focused window" toggle. When enabled, the
dictation pipeline sets the clipboard and then sends a Ctrl+V / Cmd+V
keystroke to whatever window currently has focus — the common case after a
global-hotkey dictation, since Kon's own window never stole focus.
Backend (src-tauri/src/commands/paste.rs) probes for a platform paste tool
and falls back cleanly:
- Linux Wayland: wtype > ydotool > xdotool
- Linux X11: xdotool > ydotool > wtype
- macOS: osascript System Events keystroke
- Windows: PowerShell WScript.Shell SendKeys
detect_paste_backends is a pure probe used by Settings to describe the
available backend next to the toggle (or nudge the user to install one).
paste_text always copies first, so auto-paste failure degrades to the
existing clipboard-only behaviour and surfaces a warn toast.

Two new registry entries (crates/core/src/model_registry.rs):
- whisper-distil-small-en — 336 MB, ~6× faster than whisper-small-en
- whisper-distil-large-v3 — 1.55 GB, near large-v3 accuracy at medium size
Both are whisper.cpp-compatible GGML binaries hosted on HF by the
distil-whisper org; no runtime change, just wider model choice. English-only
by design (matches upstream Distil-Whisper).
The Settings model picker widens to six options — Tiny, Base, Small,
Distil-S, Medium, Distil-L — ordered roughly by accuracy. Download/load
commands now take the resolved model id (whisper-distil-*) instead of the
lowercased label, so the frontend owns the label↔id mapping.

Previously profile_terms only reached the LLM cleanup stage as the
dictionary_terms suffix. Whisper decoded without any vocabulary hint, so
domain names ('Wren', 'CORBEL') were misspelled on the first pass and the
LLM had to guess at the correction.
build_initial_prompt (src-tauri/src/commands/mod.rs) collapses caller /
profile / terms into a single Whisper prompt:
caller_prompt > profile_prompt + "Vocabulary: <terms>." > None
transcribe_pcm, transcribe_file, and start_live_transcription_session all
route through the helper, so the three paths stay in lockstep.

kon-llm now owns a real LlamaBackend + LlamaModel, with three Qwen3 tiers
(1.7B Q4, 4B-Instruct-2507 Q4, 14B Q5) selectable per hardware. Downloads
are resumable with SHA-256 verification and stored under ~/.kon/models/llm.
Engine exposes three high-level surfaces — all greedy/temp-0, GBNF-constrained
where output shape matters:
- cleanup_text (prompt-injection-hardened system prompt; profile terms
appended as "preserve these spellings" suffix)
- decompose_task (3–7 micro-steps, constrained JSON array)
- extract_tasks (optional-array; empty when no explicit commitments)
post_process_segments now takes an Option<&LlmEngine> and, when loaded and
format_mode != Raw, joins segments → cleanup → replaces segments with the
cleaned text (first segment span). Rule-based path still runs first; LLM
errors log and keep rule-based output.
Tauri commands: recommend_llm_tier, check_llm_model, download_llm_model,
load_llm_model, unload_llm_model, delete_llm_model, get_llm_status,
cleanup_transcript_text_cmd, extract_tasks_from_transcript_cmd,
decompose_and_store (LLM-backed subtasks).
Settings: AI tier toggle (off / cleanup / tasks), model picker with
downloaded/loaded status, download progress events via
kon:llm-download-progress.
Dictation: ensureLlmModelLoaded on mount, cleanupTranscriptIfEnabled after
stop when tier != off and format_mode != Raw, LLM task extraction when
tier=tasks (regex fallback on failure).
Interim: both llama-cpp-sys-2 and whisper-rs-sys statically link their own
ggml, so src-tauri/build.rs emits -Wl,--allow-multiple-definition on Linux.
Replace with a system-ggml shared-lib setup as a follow-up.

Major quality pass on top of Phase 2. Five substantive changes plus
cross-cutting touches across audio, hotkey, transcription, and Tauri
command layers.
Transcription quality
- Long-audio chunking in commands/transcription.rs: Parakeet and large
file transcription now chunk-and-recompose with overlap trimming, so
the live-path chunking advantage extends to file-based workflows.
- Stateful live speech gate in commands/live.rs on top of the earlier
duplicate-boundary filtering — distinguishes start-of-speech from
mid-speech and holds state across chunks.
Auto-learning corrections
- New crates/ai-formatting/src/correction_learning.rs: extracts user
text corrections from viewer edits and proposes additions to the
active profile's vocabulary.
- src-tauri/src/commands/profiles.rs bridge for frontend-driven
confirmation of learned terms.
- src/routes/viewer/+page.svelte hooks the learning path into the
segment-edit flow so corrections feed profile_terms without a
separate 'train this profile' UX.
Transcript profile provenance
- Migration v8 (crates/storage/src/migrations.rs) adds profile_id to
transcripts, defaulting to DEFAULT_PROFILE_ID so existing rows stay
valid.
- crates/storage/src/database.rs: TranscriptRow + CRUD carry profile_id.
- src-tauri/src/commands/transcripts.rs: add_transcript accepts and
persists profile_id.
- DictationPage.svelte + FilesPage.svelte send activeProfileId on
capture so learned corrections are attributed to the right profile.
Cleanup prompt contract
- crates/ai-formatting/src/llm_client.rs hardened: the CLEANUP_PROMPT
now specifies concrete do/do-not rules, ready for a real model-backed
cleanup pass. The llm_client is still a stub — kon-llm remains unwired
— but the prompt shape is final.
Cross-cutting polish
- Minor touches in audio (capture/decode/resample), hotkey (lib/linux/stub),
core, transcription (concurrency/model_manager/local_engine/whisper_rs),
and the rest of src-tauri/src/commands/*: error-path tightening, log
clarity, TS-migration follow-ups (@ts-nocheck additions for incremental
typing).
Verified locally: npm run check, cargo test -p kon-ai-formatting,
cargo test -p kon-storage, cargo test -p kon --lib commands::live::tests,
cargo check — all green.
Scope boundary: kon-llm crate is still a stub; task extraction remains
rule-based. Bundled local-LLM runtime is the next clean step and is not
in this commit.

Task 16 of Phase 2 Remaining. Removes the three global-dictionary Tauri
commands now that all frontend callers were migrated to the profile-scoped
equivalents in Task 15:
- list_dictionary_command
- add_dictionary_entry_command
- delete_dictionary_entry_command
Also drops the DictionaryDto and its From<DictionaryEntry> impl (dead
alongside the commands), plus the now-unused kon_storage imports
(list_dictionary, add_dictionary_entry, delete_dictionary_entry,
DictionaryEntry). The storage-layer functions and the dictionary table
itself stay until Task 17 drops them.
Codex verification point 5 cleared: zero frontend callers for the legacy
commands (or their _cmd aliases) before deletion.
cargo check -p kon: clean.
cargo test --workspace: 40 passed; pre-existing ensure_x11_on_wayland
doctest failure at src-tauri/src/lib.rs:77 unchanged.
Wholesale JS -> TS migration of the frontend — stores, utils, actions,
and all Svelte component scripts adopt type annotations. Compile-time
surfaces (app.d.ts, lib/types/) added for shared DTO types.
Build plumbing:
- package.json: dev:frontend script that runs svelte-kit sync first
- tauri.conf.json: beforeDevCommand points at dev:frontend
- run.sh: dropped the sed-hack that temporarily blanked beforeDevCommand;
now relies on npm run dev:frontend to avoid double-Vite
- jsconfig.json: allowImportingTsExtensions
Preserves all Group 1 behaviour:
- page.svelte.ts keeps loadHistory / loadTasks Tauri-first, no
localStorage; saveTranscriptMeta + mapTranscriptRow + mapTaskRow
intact; update_task_cmd and update_transcript_meta_cmd invocations
carry the correct payload shape.
- Toasts, preferences stores typed without behaviour change.
- Viewer still routes segment edits through saveTranscriptMeta; the
Task 1.5 TODO markers are gone.
taskExtractor.ts is functionally improved during the migration:
- multi-task matches in the same sentence
- list-style shopping-verb expansion (get bread, milk, and cheese)

Second dogfood sprint. Headline fix: Linux now uses native KWin/Mutter
decorations instead of fragile frameless `startResizeDragging`, which
collapsed diagonal corner resize to a single axis and made drag feel
laggy. macOS / Windows keep custom chrome via `useCustomChrome` gate.
Other changes:
- Cross-window preferences sync via `kon:preferences-changed` Tauri
event — theme and font changes propagate live to float/viewer.
- Hotkey recorder rewritten to use capture-phase document listener
gated by $effect; button focus was unreliable in webkit2gtk.
- History page redesigned for cognitive-load hygiene: title-first
compact row, inline title input, Edit popout opening /viewer in
edit mode, clipboard export as .md with YAML frontmatter, manual
tag chips + + Add tag input, header tag filter (cap 7), global
Starred filter, `tag:xyz` search syntax.
- `deriveAutoTags` kept as empty hook for post-Task-7 LLM topic tags;
research found all previous auto-tag chips redundant with row UI.
- Viewer window adds edit mode with debounced-save textarea; native
title renamed to "Kon - Transcription Editor".
- Window minimums updated per GNOME HIG + WCAG reflow research:
main 960x600, float 360x480, editor 560x520.
- Microphone picker filters raw ALSA strings (hw:, plughw:, front:,
sysdefault:, null) and dedupes by CARD=X. New `description` field
on DeviceInfo reads /proc/asound/cards so Blue Yeti shows as "Blue
Microphones" instead of the short "Microphones" card name.
- GPU reporting fixed: get_runtime_capabilities now returns
accelerators=[cpu,vulkan] and whisper.supports_gpu=true, matching
the transcribe-rs whisper-vulkan feature linked unconditionally.
- ResizeHandles kept for macOS/Windows frameless: 12px edges, 20px
corners via CSS vars, pointerdown + setPointerCapture, corners
above edges in z-order, rendered as sibling (not child) of the
animated layout root so `position: fixed` is viewport-relative.
- Dueling drag-region handlers removed — `data-tauri-drag-region` and
manual `startDragging()` were stacked on the same elements; kept
the manual handler which has the button/input early-return logic.

.github/workflows/check.yml: cargo check on Linux + Windows + macOS
plus Svelte/Vite build on every push to main and every PR. Fast
feedback without paying for the full release build.
.github/workflows/build.yml: cross-platform release build producing
.AppImage/.deb (Linux), .msi/.exe (Windows), .dmg (macOS). Triggers
on v* tag push (attaches to a draft GitHub Release) or manual
workflow_dispatch. Signing stubs commented out pending cert decisions.
run.sh: dev launcher that starts Vite, waits for port 1420, then runs
tauri dev with beforeDevCommand blanked to avoid a second Vite spawn.
Restores tauri.conf.json on exit via trap.
src-tauri/gen/schemas/linux-schema.json: Tauri-generated capability
schema for Linux; the other platform schemas (desktop, windows) were
already committed. Adds the missing sibling.

crates/storage/src/migrations.rs:
Replace naive sql.split(';') with split_statements() that tracks
BEGIN...END depth, so migrations containing trigger definitions
execute correctly instead of being split mid-block.
crates/transcription/src/lib.rs:
Re-export transcribe_rs::SpeechModel so callers in src-tauri can
reference it without adding transcribe-rs as a direct dependency.
src-tauri/src/commands/models.rs:
Use Box<dyn SpeechModel + Send> as the load_model_from_disk return
type, matching the trait object that transcription crates produce.
src-tauri/src/commands/transcripts.rs:
Remove the stale .map(|v| v as i32) casts on sample_rate and
audio_channels. InsertTranscriptParams now stores these as i64
(ebf449b), matching the i64 fields on CreateTranscriptRequest;
casting to i32 first would silently truncate large sample rates.

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.
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
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

WebKitGTK denies getUserMedia by default with no permission prompt.
Connect to the permission-request signal and auto-allow, plus enable
media-stream and media-capabilities in WebKit settings.

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).

- Share single System::new_all() in probe_system() instead of calling it twice
- Rename CpuInfo::core_count to logical_processors (sys.cpus().len() returns logical, not physical)
- Add fallback arm to probe_os() for unsupported cfg targets
- Add serde::Serialize to KonError for structured frontend error reporting
- Annotate dead code (ProviderRegistry, TranscriptMetadata) with #[allow(dead_code)] + TODO comments
- Update downstream references in recommendation tests and tauri hardware command

Float window fixes:
- Root layout now detects /float and /viewer URLs and hides Sidebar,
Titlebar, TaskSidebar for secondary windows. Belt-and-braces fix
since +layout@.svelte should handle this but may not in SPA mode.
- Float window title: "Ramble - To-do" → "Kon - To-do"
Transcription doubling guard:
- Added chunk_id deduplication set in DictationPage — if a chunk_id
has already been processed, skip the duplicate result
- Set cleared on each new recording session

Security fixes from code audit:
- CSP re-enabled in tauri.conf.json with strict directives
(was null — critical vulnerability)
- XSS fix in viewer highlightText(): HTML entities escaped before
inserting <mark> tags via {@html}
- Removed 3 unwrap() calls in rule_based.rs British English conversion
— replaced with safe let-else guards
- Removed unwrap() on main window lookup in lib.rs setup — now uses
if-let for graceful handling
- Wrapped JSON.parse in DictationPage transcription-result listener
with try/catch
Rebrand cleanup:
- Renamed all localStorage keys from ramble_* to kon_* across
7 files (stores, viewer, float, history)
12 tests passing, clippy clean.

- New probe_system command: returns RAM, CPU, OS info
- New rank_models command: scores models against detected hardware
- FirstRunPage.svelte: hardware summary, ranked model list with
"Recommended" badge on top pick, download progress bar, skip option
- First-run detection in layout: checks list_models + list_parakeet_models,
shows wizard if both empty
- Sidebar hidden during first-run for clean wizard experience
- clippy clean

- New copy_to_clipboard Tauri command using arboard 3.6
- Replaced all 5 navigator.clipboard.writeText() calls across
DictationPage, HistoryPage, FilesPage, and viewer with invoke()
- Native clipboard access independent of WebView permissions
