The desktop app is a browser now, so it cannot write files. This adds the other
half: a loopback HTTP server that serves the web build and owns the two files
the browser cannot touch -- `~/todo/BACKLOG.md`, which the user's tooling and
the todo MCP server read, and a disk copy of the note log so a wiped Chrome
profile is not a total-loss event for unsynced notes.
Notable details:
- Binds to 127.0.0.1 only. The endpoints overwrite files in the user's home
with no authentication, so a routable bind would let anything on the network
rewrite the backlog.
- Serves explicit content types. CanvasKit refuses a `.wasm` labelled anything
else and the app then renders nothing at all.
- Mirroring to disk is debounced. The store persists on every keystroke, so
mirroring eagerly meant an HTTP request plus a whole-log write per character;
IndexedDB still gets every keystroke, only the durability copy waits.
Separately, this fixes a pre-existing destructive bug found while testing:
`settings_screen_test` did real file I/O and overwrote the user's canonical
`~/todo/BACKLOG.md` with a single fake note on *every* `flutter test` run. It
went unnoticed because the app rewrites the file whenever it launches. The
export destination is now injectable and the test redirects it to a temp dir;
verified that a full suite run leaves the real file byte-identical.

First step of moving the desktop app off Flutter's Linux embedder, which tops
out at ~20fps at 4K (see docs/desktop-performance-findings.md). Android is
unaffected and keeps every existing code path.
The blocker was that `dart:io` was imported by note_repository, capture_screen
and settings_screen. On web it compiles to a stub and then throws at runtime --
the first web build rendered a blank white window. So each `dart:io` use now
sits behind a conditional export, with the shared logic hoisted into pure Dart:
- note_repository loses `dart:io`/sqlite entirely. Platform wiring moves to
repository_factory{,_io,_web}, and the legacy sqlite import moves to its own
io-only library. The HLC-from-updated_at seeding is preserved verbatim, so
independently-migrating devices still resolve pre-cutover edits by real edit
time.
- Notes persist to IndexedDB on web, not localStorage: the log is the primary
copy of the backlog and localStorage caps at ~5-10MB and is evicted eagerly.
- BACKLOG.md and the explicit Export keep working through a local wrapper
(added next). A browser cannot write `~/todo/BACKLOG.md`, and the user's
tooling plus the todo MCP server read that path, so leaving it to rot was not
an option. Writes are best-effort so the app still works with no wrapper.
- Notes are also mirrored to the wrapper's on-disk copy, so a wiped Chrome
profile is not a total-loss event for notes that have not reached GitHub yet.
`openRepository` is split so `openRepositoryIn` keeps the migration tests; the
suite stays at 174 green and 100% coverage.

Standardizes on the same stricter lint set + shared analysis_options.yaml
used by diet-guard/app and the new habit_stack app. Fixes all 127 issues
surfaced: dart fix --apply for imports/cascades/sorting, unawaited() on
fire-and-forget Futures, bare catch(e) narrowed to on Exception catch(e)
(matching diet_guard's existing pattern), one documented ignore for a
deliberate TypeError catch around untrusted peer JSON, and missing
public-member doc comments throughout. No behavior change: 174/174 tests
pass, 100% line coverage maintained.

The desktop and phone split-brained for 5 days (39 vs 30 notes) after the
crdt_sync cutover because one device kept running the pre-migration build
— and nothing in the UI ever said a sync had failed or skipped a peer:
- SyncResult now reports peer files that were listed but couldn't be
fetched/decoded (skippedFiles) instead of dropping them silently.
- Auto-sync no longer swallows errors: every sync (manual or automatic)
records a persisted last-sync status shown in a status line under the
editor, with failures in the error color.
- Desktop actually background-syncs now: focus loss (inactive/hidden,
debounced 5s) triggers a sync — Flutter Linux rarely delivers the
`paused` event the old code relied on. `paused` still syncs immediately
for Android.

crdt_sync v0.3.0 now provides canAccessRepo() + deleteFile(), so todo syncs
through the one shared client like the other apps instead of its own copy.
SyncService loses its SHA-tracking (crdt_sync's putFileText self-resolves the
sha); lib/sync/github_client.dart + its test are deleted; capture/settings/
sync_smoke repoint to the shared client. flutter analyze clean, 169 tests at
100% coverage, device-verified (27-note backlog intact, no crash).

NoteRepository is rewritten on crdt_sync's LogStore: each Note is stored *as*
a Record (per-field LWW + sticky tombstone), so the on-disk log IS the sync
wire format. Its public API is unchanged (upsert/delete/listNotes/watchNotes/
watchCount/importNotes/changes/nodeId), so the UI and most tests are
untouched; only the internals, the two sync methods (getChangeset/merge ->
exportLog/importLog over a Log), and the changeset-specific tests change.
Filtering/sorting now run in Dart over the in-memory log; watchNotes/watchCount
seed synchronously in onListen to avoid a subscription race.
SyncService moves from per-device sqlite changesets to per-device crdt_sync
Logs under a new todo-sync/notes/ path (clean format cutover; old clients
can't misread a new file). todo's own GitHubClient transport is kept.
One-time migration in NoteRepository.open: reads the legacy sqlite DB (kept
untouched as a safety net; the dep stays only for this), seeds every note --
tombstones included -- into the log with each field's HLC derived from its
updated_at (so a pre-cutover edit still wins by real edit time across two
independently-migrating devices), reuses the legacy node id, and sets a
persisted "migrated" flag so it never re-runs.
Verified: flutter analyze + dart format clean; 178 tests at 100% coverage
(incl. migration, tombstone, restore-race, and corrupt-peer cases). Device
verified on dev.kuhy.todo: real backlog of 27 live notes (+5 tombstones)
migrated intact -- confirmed against a pulled sqlite backup, the pulled
LogStore JSON, and the app's own "27 saved" -- notes render with status/
priority/dates, no crash, migration one-time.

The capture screen fed the on-disk BACKLOG.md backup off an always-live
watchNotes() subscription, so every keystroke re-queried the whole table,
re-parsed every row, and rebuilt the full Markdown export on the UI
isolate — O(notes) per character. It also fired a whole-screen setState
just to update the "Saved locally" timestamp.
- Add NoteRepository.changes: an O(1) broadcast tick after each write
(upsert/delete/merge; importNotes transitively). LocalBackup now pulls
notes via an injected fetcher only when its 2s debounce fires, so the
query + parse + Markdown export runs at most once per idle window
instead of on every keystroke. Capture listens to changes, not
watchNotes; a launch-time schedule() keeps BACKLOG.md fresh.
- Scope the save indicator to a ValueNotifier/ValueListenableBuilder so a
keystroke updates one line of text, not the AppBar/dropdowns/editor.
- Key list tiles by note id for identity-based reorder diffing.
Measured on a 4K/144Hz desktop the UI-thread build stays <=3.3ms;
coverage held at 100% on all changed files.

todo-sync, diet-guard-sync, and screen-locker-sync were folded into
one private github.com/kuhyx/syncs monorepo, each keeping its own
subdirectory as the Contents-API path prefix. Update the default
owner/repo, the changeset path prefix, and add a persisted-value
migration so an already-installed device that saved the old
'todo-sync' repo name picks up 'syncs' on next load.

The token moved from plaintext SharedPreferences into flutter_secure_storage
(Android Keystore / libsecret). Only the non-secret owner/repo/clientId stay in
prefs. Migration is confirm-before-delete: load() reads the keystore first and
falls back to the legacy plaintext token, migrating it only once a secure write
succeeds; save() likewise keeps writing plaintext if no secret service is
available, so we degrade to — never below — the old behaviour.
157 tests, 100% line coverage, analyze clean. Verified on-device: Settings
stays connected and sync succeeds after the one-time migration.

Previously "Connect GitHub" (OAuth device flow) still required entering an
OAuth App client id and owner/repo — friction that returned on every
reinstall once shared_prefs were wiped.
- Bake the app's own device-flow OAuth App client id in as
SyncSettings.defaultClientId and default to it in load() (alongside the
existing kuhyx/todo-sync repo default). A device-flow client id is a
public identifier, not a secret, so it is safe to commit.
- Settings now leads with a single "Connect GitHub" button; the manual
client-id / token fields and Test connection move under an "Advanced"
expander. Result: fresh install (or post-reinstall) is one tap →
authorize the code in the browser → synced. No tokens, no setup.
Note: an OAuth App authorizes with the classic `repo` scope (all repos),
broader than the prior fine-grained PAT — the trade-off for one-tap
device-flow convenience. 151 tests, 100% line coverage.

Third durability layer beside GitHub auto-sync and Android Auto Backup:
a plain, human/LLM-readable Markdown file kept current on local disk.
- LocalBackup (lib/sync): pure, injectable file IO. scheduleExport()
debounces writes (a burst of keystrokes → one export); recover() parses
the file back into notes. Reused NotesMarkdown serializer.
- CaptureScreen wires it: on launch, recover into an *empty* DB only (so a
stale backup never clobbers existing notes), then keep the backup current
as notes change. Platform path = ~/todo/BACKLOG.md on desktop (the path
the user's workflow already reads) or the app documents dir on mobile
(covered by Android Auto Backup). File IO is injected in tests.
- Added fake_async dev dep to unit-test the debounce with a virtual clock.
151 tests, 100% line coverage.

- Inject an optional http.Client into CaptureScreen (mirroring SettingsScreen)
so the configured sync path runs against a MockClient instead of the network;
capture_screen.dart now 100%.
- Mock the file_selector and url_launcher platform interfaces and the clipboard
channel so the import flow, _openPage launch, and the device-code dialog's
error/Cancel/Open paths are exercised deterministically (no hangs, no timers).
- Add unit tests for the remaining fallbacks/defaults: copyWith no-arg paths,
GitHubApiException.toString, default-constructed clients, empty NoteFilter,
the v1->v2 status-column migration, and the export/import error branches.
- coverage:ignore the private static-only NotesMarkdown ctor.
101 tests, all green in ~5.5s. Line coverage 96.2% -> 100%.

Notes list & filtering:
- Text-search filter plus independent date-range filters for both created
and last-updated (AND-combined), a priority filter, and a new status
filter. Default view hides Done/Abandoned and renders as "unfiltered"
(no badge for the default state); fixed badge clipping.
- NoteSort options wired into the list UI; watchCount() for the "N saved".
Status & priority:
- New Status enum (toDo/inProgress/Done/Abandoned) as a settable + filterable
attribute on every note, with capture-screen dropdown.
- Removed "None" priority: every note is Low/Medium/High, default Medium.
Schema migration v2->v3 rewrites legacy priority 0 -> Medium.
Export / import:
- NotesMarkdown round-trippable single-file format with HTML-comment markers.
- Settings "Export notes" (mobile share sheet / desktop writes ~/todo/BACKLOG.md)
and "Import notes" (file picker + safe newer-wins merge by id).
Structured template:
- Every new note pre-fills the richer what/where/must/nice/out/done/depends/
estimate/refs scaffold.
Tests:
- New fast (~5s), deterministic suite via FakeNoteRepository (no DB timers) and
injected http/file-selector/url-launcher fakes. 86 tests, 96.2% line coverage
(note.dart & sync_service.dart at 100%, settings 98.7%). Mobile-only share
branch excluded via coverage:ignore (unreachable on the Linux test host).

Flutter app for Android + Linux desktop. Captures ideas with per-keystroke local autosave to a CRDT-backed SQLite store (sqlite_crdt), and syncs through a private GitHub repo using per-device changeset files (conflict-free last-writer-wins merge). Includes GitHub OAuth device-flow sign-in with PAT fallback, a barebones notes list, and sync settings.
