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)

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
