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)

ai-formatting:
- rule_based.rs: collapse_repetitions() merges adjacent duplicate
tokens like 'I I can' -> 'I can' and 'think think that' -> 'think
that'. Normalises case and punctuation before comparison.
- pipeline.rs: post_process now calls collapse_repetitions when
format_mode is Clean or Smart. Added unit coverage.
audio:
- capture.rs: replace the seven deprecated cpal DeviceTrait::name()
call sites with a device_display_name() helper that uses the
non-deprecated description() path. Keeps identical behaviour,
silences compile warnings, ready for cpal upgrade.
Addresses the 'Christ. Christ.' live-transcription boundary duplicate
Jake saw during Group 1 dogfooding. Does not fix all cross-chunk
overlap cases (see live.rs OVERLAP_SAMPLES for the root cause) but
catches the common stutter pattern at post-processing.

@tailwindcss/vite:generate:serve threw 'Invalid declaration:
getCurrentWindow' on ResizeHandles.svelte?svelte&type=style&lang.css
even after comment sanitisation. The style block is plain CSS with no
Tailwind directives, but the per-component virtual CSS module route
was hitting a parse bug in the Tailwind v4 + Svelte 5 combination.
Workaround: move the CSS into app.css (class names are already
component-specific, no scoping loss) and drop the component-local
<style> block. This sidesteps the virtual-module route entirely.

Follow-up to 92ac7ea. Two apostrophes remained (KWin's and don't)
that kept tripping Tailwind v4 JIT the same way. Removed.

transcribe-rs 0.3.10's ParakeetModel::transcribe_raw ignores its
options argument and calls self.infer(samples, &TimestampGranularity::default())
where default is TimestampGranularity::Token — per-subword segments.
That surfaces in Kon as output like 'T Est Ing One , Two , Three . W Ow ,
This Is T Ri Ble .' because DictationPage joins segment texts with ' '.
Introduce a thin ParakeetWordGranularity wrapper that implements
SpeechModel and overrides transcribe_raw to call the concrete
ParakeetModel::transcribe_with() with ParakeetParams { timestamp_granularity:
Some(Word) }. Pre-existing bug unrelated to Phase 2 work — surfaced during
Group 1 dogfooding because Parakeet was being tested for the first time.

Follow-up to d1d344b. Tailwind's scanner still saw backtick-quoted
fragments like `decorations: false` and `position: fixed` in the
script comments as CSS property declarations, tripping on the next
JS identifier (getCurrentWindow). Removing all backticks from the
comment block sidesteps the entire scanner path.

Tailwind v4 JIT scanner mis-tokenised the comment 'Tauri`s `data-tauri-drag-region`'
as an unterminated string literal, breaking dev-server HMR. Comment rewritten
to avoid apostrophes near backticks. No behaviour change.

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.

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).
HANDOVER.md was a working-notes file from the 2026/04/04 session that
was never committed. It described live transcription as broken — which
was fixed in the 2026/04/17 sprint. Leaving it untracked was a trap
for anyone cloning the repo. Deleted.
.firecrawl/ added to .gitignore (web-scraping cache, no repo value).

.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.

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.

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.
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.
