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.

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.

Adds `tech` (stack + versions) and `ask` (decisions needing human
approval) sections; renames `out` → `never` to match the three-tier
always/ask/never boundary system from Addy Osmani's good-spec article.

Notes were previously only openable via a quick-actions sheet; you
could not read or edit a note in full. Add a shared NoteEditor used by
both the capture and detail screens, plus selectable templates and a
rendered Markdown view.
- note_template.dart: pure assemble/parse layer over a Markdown subset
(# title, ## sections + italic guidance, dropping empty sections).
assemble(parse(text)) is idempotent for conforming text; non-conforming
/ legacy / freeform text is reported so the UI falls back to raw,
untouched. Two templates: llm-design-spec (default) and blank.
- note_editor.dart: View / Guided / Raw modes. Guided is an inline
Stepper (one step per section with its guidance); View renders the
note via MarkdownView; Raw is the verbatim text. Guided is offered
only for structured templates; switching to it is blocked when the
raw text no longer conforms.
- markdown_view.dart: lean read-only renderer for the note subset,
wrapped in a SelectionArea for copy-out.
- note_detail_screen.dart: full-screen note; opens in View, edits
persist immediately, priority/status dropdowns, delete.
- capture_screen / notes_list_screen wired to the new editor and detail
screen (tap a note opens it; quick actions move to the overflow button).
The editor is a view over plain text, so CRDT storage and Markdown
export/sync are unaffected. 138 tests, 100% line coverage.

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.
