+
+> [!WARNING]
+> Verstak is currently **alpha software**. APIs, storage formats and packaging may change before the first stable release. Use a test vault and keep backups of important data.
+
+## What is Verstak?
+
+Verstak is a local-first workbench that keeps the context around your work in one place.
+
+A **Deal** can represent almost anything:
+
+* a software project;
+* a client or customer;
+* a server or infrastructure site;
+* a device under repair;
+* an article or research topic;
+* a training course;
+* a personal long-term project.
+
+Normally, information about such work is scattered across directories, notes, browser tabs, task managers, password managers, terminal history and memory.
+
+Verstak brings it together in a local **vault** that remains under your control.
+
+No account, cloud service or sync server is required for local use.
+
+## Verstak in use
+
+| Overview: return to a Deal and see its recent work, captures and items that need attention. | Files: manage ordinary folders and documents inside a Deal. |
+| --- | --- |
+| ![Current Verstak Overview in a test vault](docs/screenshots/overview-en.png) | ![Current Verstak Deal files in a test vault](docs/screenshots/files-en.png) |
+
+| Notes: keep Markdown notes next to the Deal they describe. | Journal: record a completed session and retain its context. |

+
+## Download and install
+
+Download the latest build from the
+[GitHub Releases page](https://github.com/mirivlad/verstak/releases/latest).
+
+Release packages already include the matching official plugins.
+
+| System                            | Download                                  | Installation                                  |
+| --------------------------------- | ----------------------------------------- | --------------------------------------------- |
+| Debian 13 / Ubuntu 24.04 or newer | `verstak_<version>_amd64.deb`             | Install through APT.                          |
+| Other x86_64 Linux distributions  | `verstak-linux-x86_64-<version>.AppImage` | Make the file executable and run it.          |
+| Windows 10/11 x64                 | `verstak-windows-amd64-<version>.zip`     | Extract the archive and launch `Verstak.cmd`. |
+
+### Debian and Ubuntu
+
+```bash
+sudo apt install ./verstak_*_amd64.deb
+```
+
+Launch Verstak from the application menu or run:
+
+```bash
+verstak
+```
+
+### AppImage
+
+```bash
+chmod +x verstak-linux-x86_64-*.AppImage
+./verstak-linux-x86_64-*.AppImage
+```
+
+On a system without FUSE support:
+
+```bash
+APPIMAGE_EXTRACT_AND_RUN=1 ./verstak-linux-x86_64-*.AppImage
+```
+
+### Windows portable version
+
+1. Download `verstak-windows-amd64-<version>.zip`.
+2. Extract it to a local directory.
+3. Run `Verstak.cmd`.
+
+Do not run Verstak directly from inside the ZIP archive or from a network share.
+
+Verstak uses the Microsoft WebView2 Runtime. It is already included with Windows 11 and most current Windows 10 installations. If Verstak does not start, install the
+[Microsoft WebView2 Runtime x64](https://go.microsoft.com/fwlink/p/?LinkId=2124701).
+
+## Background and tray mode
+
+Closing the main window keeps Verstak running in the system tray. Use **Show Verstak** to bring it back and **Quit** to exit the application completely. This lets scheduled Todo reminders continue while the window is hidden.
+
+### Verify a download
+
+Each release includes a `SHA256SUMS` file.
+
+On Linux:
+
+```bash
+sha256sum -c SHA256SUMS --ignore-missing
+```
+
+## First start
+
+### 1. Create or open a vault
+
+A **vault** is the root directory where Verstak stores your work.
+
+Choose a writable local directory. For example:
+
+```text
+Documents/
+└── Verstak/
+```
+
+Your files and notes remain ordinary files that can be accessed without Verstak.
+
+### 2. Create your first Deal
+
+Inside the vault, create a Deal for a project, client, server, device or another area of work.
+
+For example:
+
+```text
+Home server
+Customer Alpha
+Verstak development
+3D printer
+Training course
+```
+
+### 3. Add context
+
+Open the Deal and add the information needed to return to it later:
+
+* notes and decisions;
+* documents and source files;
+* useful links;
+* access information;
+* journal entries;
+* tasks;
+* materials captured from the browser.
+
+### 4. Return through Overview
+
+The Overview screen shows recent changes, unfinished captures, activity and other useful entry points back into your work.
+
+## How Verstak stores data
+
+Verstak follows several principles:
+
+* your vault is local and works without an account or internet connection;
+* files and notes remain readable outside the application;
+* synchronization is optional and is not the source of truth;
+* the user should understand where data is stored and what happens to it;
+* application tools are provided by plugins rather than being permanently embedded into the core.
+
+The desktop application loads plugins from a `plugins/` directory located beside the executable.
+
+## Browser integration
+
+The optional browser extension can send the following into Browser Inbox:
+
+* the current page;
+* selected text;
+* a link;
+* a downloaded or selected file.
+
+Repository:
+
+[mirivlad/verstak-browser-extension](https://github.com/mirivlad/verstak-browser-extension)
+
+To connect the extension:
+
+1. Open Browser Inbox settings in Verstak.
+2. Copy the Receiver URL and Pairing Token.
+3. Paste them into the extension settings.
+4. Save the settings and send a test page.
+
+Passive domain activity tracking is disabled by default. When enabled, it sends bounded time totals by normalized domain. It does not send page contents, keystrokes or full browsing history.
+
+## Optional synchronization
+
+Local use does not require a server.
+
+For synchronization between devices, deploy the optional self-hosted
+[Verstak Sync Server](https://github.com/mirivlad/verstak-sync-server).
+
+Each vault is connected separately. The local vault remains the primary copy of your data.
+
+## Build from source
+
+### Requirements
+
+* Go 1.24 or newer;
+* Node.js 20 or newer with npm;
+* Python 3;
+* Git;
+* Wails v2 build dependencies;
+* WebKitGTK development packages on Linux.
+* Ayatana AppIndicator development files on Linux (`sudo apt install libayatana-appindicator3-dev`).
+
+See the
+[Wails installation documentation](https://wails.io/docs/gettingstarted/installation/)
+for distribution-specific dependencies.
+
+### Clone the repositories
+
+The desktop, SDK and official plugin repositories must be cloned as sibling directories:
+
+```text
+verstak-source/
+├── verstak/
+├── verstak-sdk/
+└── verstak-official-plugins/
+```
+
+```bash
+mkdir verstak-source
+cd verstak-source
+
+git clone https://github.com/mirivlad/verstak.git
+git clone https://github.com/mirivlad/verstak-sdk.git
+git clone https://github.com/mirivlad/verstak-official-plugins.git
+```
+
+### Build
+
+```bash
+cd verstak-sdk
+./scripts/build.sh
+
+cd ../verstak-official-plugins
+./scripts/build.sh
+
+cd ../verstak
+./scripts/install-dev-plugins.sh
+./scripts/build.sh
+```
+
+The resulting application will be located at:
+
+```bash
+./build/bin/verstak-desktop
+```
+
+Run it with additional diagnostics:
+
+```bash
+./build/bin/verstak-desktop --debug
+```
+
+## Build release packages locally
+
+These commands create local artifacts in `release/`. They do not publish a GitHub Release.
+
+### Debian package
+
+```bash
+./scripts/package-deb.sh v0.1.0-alpha.1
+```
+
+### AppImage
+
+```bash
+./scripts/package-appimage.sh v0.1.0-alpha.1
+```
+
+### Windows portable ZIP
+
+The Windows archive can be cross-compiled on Linux using MinGW:
+
+```bash
+sudo apt install gcc-mingw-w64-x86-64 zip
+./scripts/package-windows-portable.sh v0.1.0-alpha.1
+```

+
+> [!WARNING]
+> Верстак пока находится на стадии **alpha**. До первого стабильного выпуска могут меняться API, форматы хранения и состав пакетов. Для знакомства используйте тестовый vault и сохраняйте резервные копии важных данных.
+
+## Что такое Верстак
+
+Верстак — это local-first рабочая среда, которая удерживает в одном месте контекст вокруг ваших дел.
+
+**Делом** может быть что угодно:
+
+* программный проект;
+* клиент или заказчик;
+* сервер или площадка;
+* ремонтируемое устройство;
+* статья или исследование;
+* учебный курс;
+* личный долгосрочный проект.
+
+Обычно информация о таком деле расползается по папкам, заметкам, браузерным вкладкам, менеджерам задач, хранилищам паролей, истории терминала и памяти.
+
+Верстак собирает её в один локальный **vault**, который остаётся под вашим контролем.
+
+Для локальной работы не нужны учётная запись, облачный сервис или собственный сервер.
+
+## Верстак в работе
+
+| Обзор: возвращает к делу и показывает недавнюю работу, входящие и то, что требует внимания. | Файлы: обычные папки и документы прямо внутри дела. |
+| --- | --- |
+| ![Актуальный экран «Обзор» Верстака в тестовом vault](docs/screenshots/overview-ru.png) | ![Актуальные файлы дела в тестовом vault Верстака](docs/screenshots/files-ru.png) |
+
+| Заметки: Markdown-заметки остаются рядом с делом, которое они описывают. | Журнал: фиксирует завершённую работу и её контекст. |
+| --- | --- |
+| ![Актуальные заметки Верстака в тестовом vault](docs/screenshots/notes-ru.png) | ![Актуальный журнал Верстака в тестовом vault](docs/screenshots/journal-ru.png) |
+
+## Основные возможности
+
+| Возможность              | Что она даёт                                                                                   |
+| ------------------------ | ---------------------------------------------------------------------------------------------- |
+| **Дела**                 | Объединяют файлы, заметки и историю работы вокруг проектов, клиентов и других направлений.     |
+| **Файлы**                | Позволяют работать с обычными файлами, расположенными внутри vault.                            |
+| **Заметки**              | Markdown-заметки, обзорные страницы и связи между материалами.                                 |
+| **Обзор**                | Помогает быстро вернуться к недавней работе и увидеть то, что требует внимания.                |
+| **Входящие из браузера** | Принимают страницы, ссылки, выделенный текст и файлы из браузера.                              |
+| **Активность и журнал**  | Помогают восстановить рабочие сессии и превратить выбранную активность в записи журнала.       |
+| **Задачи**               | Необязательные списки задач внутри отдельных дел и во всём vault.                              |
+| **Поиск**                | Ищет по заметкам, файлам и данным поддерживаемых плагинов.                                     |
+| **Корзина**              | Позволяет восстановить удалённое или окончательно удалить его из одного общего раздела.        |
+| **Секреты**              | Хранит доступы и учётные данные рядом с делом, к которому они относятся.                       |
+| **Шаблоны**              | Создают повторяемую структуру для однотипных дел.                                              |
+| **Плагины**              | Позволяют добавлять, заменять и отключать инструменты, не превращая Верстак в жёсткий монолит. |
+| **Синхронизация**        | Необязательно синхронизирует vault между устройствами через собственный сервер.                |
+
+## Скачивание и установка
+
+Готовые сборки находятся на странице
+[GitHub Releases](https://github.com/mirivlad/verstak/releases/latest).
+
+В релизные пакеты уже входят совместимые версии официальных плагинов. Устанавливать их отдельно не требуется.
+
+| Система                          | Какой файл скачать                       | Как установить                               |
+| -------------------------------- | ---------------------------------------- | -------------------------------------------- |
+| Debian 13 / Ubuntu 24.04 и новее | `verstak_<версия>_amd64.deb`             | Установить через APT.                        |
+| Другие дистрибутивы Linux x86_64 | `verstak-linux-x86_64-<версия>.AppImage` | Сделать файл исполняемым и запустить.        |
+| Windows 10/11 x64                | `verstak-windows-amd64-<версия>.zip`     | Распаковать архив и запустить `Verstak.cmd`. |
+
+### Debian и Ubuntu
+
+```bash
+sudo apt install ./verstak_*_amd64.deb
+```
+
+После установки запустите Верстак из меню приложений или командой:
+
+```bash
+verstak
+```
+
+### AppImage
+
+```bash
+chmod +x verstak-linux-x86_64-*.AppImage
+./verstak-linux-x86_64-*.AppImage
+```
+
+Если в системе нет поддержки FUSE:
+
+```bash
+APPIMAGE_EXTRACT_AND_RUN=1 ./verstak-linux-x86_64-*.AppImage
+```
+
+### Портативная версия для Windows
+
+1. Скачайте `verstak-windows-amd64-<версия>.zip`.
+2. Распакуйте архив в локальную папку.
+3. Запустите `Verstak.cmd`.
+
+Не запускайте Верстак прямо из ZIP-архива или с сетевого диска.
+
+Верстак использует Microsoft WebView2 Runtime. Он уже присутствует в Windows 11 и большинстве актуальных установок Windows 10. Если приложение не запускается, установите
+[Microsoft WebView2 Runtime x64](https://go.microsoft.com/fwlink/p/?LinkId=2124701).
+
+## Фоновая работа и трей
+
+Закрытие главного окна не завершает Верстак: приложение остаётся в системном трее. Выберите **Show Verstak**, чтобы вернуть окно, или **Quit**, чтобы полностью завершить приложение. Благодаря этому напоминания Todo продолжают работать, пока окно скрыто.
+
+### Проверка скачанного файла
+
+В каждый релиз входит файл `SHA256SUMS`.
+
+Проверка в Linux:
+
+```bash
+sha256sum -c SHA256SUMS --ignore-missing
+```
+
+## Первый запуск
+
+### 1. Создайте или откройте vault
+
+**Vault** — это корневая папка, в которой Верстак хранит ваши дела.
+
+Выберите доступный для записи локальный каталог. Например:
+
+```text
+Документы/
+└── Верстак/
+```
+
+Файлы и заметки остаются обычными файлами. Их можно открыть и без Верстака.
+
+### 2. Создайте первое дело
+
+Внутри vault создайте дело для проекта, клиента, сервера, устройства или другого направления работы.
+
+Например:
+
+```text
+Домашний сервер
+Заказчик Альфа
+Разработка Верстака
+3D-принтер
+Учебный курс
+```
+
+### 3. Соберите контекст
+
+Добавьте в дело всё, что поможет вернуться к нему через неделю, месяц или год:
+
+* заметки и принятые решения;

+
+## Как Верстак хранит данные
+
+Верстак придерживается нескольких принципов:
+
+* vault хранится локально и доступен без учётной записи и интернета;
+* файлы и заметки остаются читаемыми вне приложения;
+* синхронизация является дополнением, а не источником истины;
+* пользователь должен понимать, где находятся его данные и что с ними происходит;
+* инструменты реализуются плагинами, а не навсегда встраиваются в ядро.
+
+Настольное приложение загружает плагины из каталога `plugins/`, расположенного рядом с исполняемым файлом.
+
+## Интеграция с браузером
+
+Необязательное расширение позволяет отправлять во «Входящие из браузера»:
+
+* текущую страницу;
+* выделенный текст;
+* ссылку;
+* выбранный или скачанный файл.
+
+Репозиторий расширения:
+
+[mirivlad/verstak-browser-extension](https://github.com/mirivlad/verstak-browser-extension)
+
+Чтобы подключить расширение:
+
+1. Откройте настройки «Входящих из браузера» в Верстаке.
+2. Скопируйте адрес приёмника и токен сопряжения.
+3. Вставьте их в настройки расширения.
+4. Сохраните настройки и отправьте тестовую страницу.
+
+Пассивный учёт активности по доменам по умолчанию отключён. После включения расширение передаёт только ограниченные интервалы времени для нормализованных доменов. Оно не отправляет содержимое страниц, нажатия клавиш или полную историю посещений.
+
+## Необязательная синхронизация
+
+Для локального использования сервер не нужен.
+
+Для синхронизации между устройствами можно развернуть собственный
+[Verstak Sync Server](https://github.com/mirivlad/verstak-sync-server).
+
+Каждый vault подключается отдельно. Основной копией данных остаётся локальный vault.

+# Native Notifications, Tray, and Public README Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Deliver native Todo reminders and Windows/Linux tray operation, then publish updated alpha artifacts and public README documentation with real application screenshots.
+
+**Architecture:** Desktop core stores and delivers plugin-owned notification schedules and controls the tray lifecycle. Todo uses the public plugin API to replace its desired reminders. A small core tray adapter keeps the Wails process alive after window close. Documentation uses the supplied English and Russian README sources plus screenshots from an actual test vault.
+
+**Tech Stack:** Go 1.24, Wails v2.12 runtime notifications, `getlantern/systray`, plain JavaScript plugin API, Node smoke tests, Playwright, bash packaging.
+
+## Global constraints
+
+- Support Windows and Linux only; no background daemon after an explicit Quit.
+- Closing a window hides it; only tray **Quit** ends the process.
+- `verstak.todo` requires `verstak/core/notifications/v1` and `notifications.schedule`.
+- Plugins cannot receive Wails runtime access.
+- Keep Wails generated bindings out of commits.
+- Commit each independent change and immediately push it to GitHub and `mirror`.

+- Create: `internal/shell/tray/controller.go`
+- Create: `internal/shell/tray/controller_test.go`
+- Modify: `main.go`
+- Modify: `internal/api/app.go`
+- Modify: `internal/api/app_test.go`
+- Modify: `go.mod`
+- Modify: `go.sum`
+
+**Interfaces:**
+- `tray.Start(icon []byte, actions Actions) error`, with `Actions.Show` and `Actions.Quit`.
+- `App.BeforeClose(ctx) bool` hides and returns true unless `App.Quit()` made shutdown explicit.
+- `App.ShowWindow()` reveals the existing window.
+
+- [ ] **Step 1: Add failing close-policy and tray action tests**
+
+```go
+func TestBeforeCloseHidesWindowUntilExplicitQuit(t *testing.T) {
+    app, window := newWindowTestApp(t)
+    if prevent := app.BeforeClose(context.Background()); !prevent || window.hideCalls != 1 { t.Fatal("ordinary close must hide") }
+    app.Quit()
+    if prevent := app.BeforeClose(context.Background()); prevent { t.Fatal("explicit quit was prevented") }
+}
+```
+
+Use a fake tray adapter to assert exactly two labels, **Show Verstak** and **Quit**, and one callback invocation per click.
+
+- [ ] **Step 2: Confirm red**
+
+```bash
+GOCACHE=/tmp/verstak-go-cache go test ./internal/api -run TestBeforeCloseHidesWindowUntilExplicitQuit -count=1
+GOCACHE=/tmp/verstak-go-cache go test ./internal/shell/tray -count=1
+```
+
+Expected: absent packages/methods.
+
+- [ ] **Step 3: Implement adapter and Wails wiring**
+
+Add `github.com/getlantern/systray@v1.2.2`. The production adapter calls nonblocking `systray.Register`, sets compact source-controlled PNG bytes derived from the existing tracked logo, and starts goroutines for the two click channels. `main.go` registers `OnBeforeClose` and uses `options.SingleInstanceLock` whose second launch calls `app.ShowWindow`. Do not embed ignored Wails-generated files from `build/`.

+# Native Notifications and System Tray Design
+
+**Status:** approved for implementation on 2026-07-14
+
+## Goal
+
+Deliver Todo reminders as native notifications on Windows and Linux, and keep
+Verstak running in the system tray when its main window is closed. The feature
+must work in the portable Windows archive, Debian package, and AppImage.
+
+## Scope
+
+- The desktop core owns notification delivery, scheduling, and tray lifetime.
+- `verstak.todo` owns the Todo-specific reminder policy and text.
+- No new official notifications plugin is introduced. A dynamic plugin cannot
+  call Wails directly, so it cannot be the native-notification transport.
+- macOS is out of scope for this alpha. The interfaces remain platform-neutral
+  where that costs nothing.
+
+## Tray behavior
+
+On Windows and Linux, a tray icon is registered before the Wails event loop
+starts. Its menu contains exactly two actions:
+
+1. **Show Verstak** — shows and focuses the existing main window.
+2. **Quit** — exits the process deliberately.
+
+Closing the main window with its window-manager close control hides the window
+and keeps the process, plugins, local browser receiver, and reminder scheduler
+alive. It does not terminate the application. The quit action temporarily
+allows the close lifecycle to finish and then exits normally.
+
+The app has a single-instance lock. If a user launches the executable while an
+instance is hidden in the tray, the existing instance shows its window instead
+of creating a second process.
+
+The implementation uses `github.com/getlantern/systray` through a small
+`internal/shell/tray` adapter. It uses `Register`, rather than its blocking
+`Run`, so Wails remains the owner of the GUI event loop. A compact PNG derived
+from the tracked project logo is encoded in the tray package, so a clean build
+does not depend on ignored Wails-generated icon files. The library accepts PNG
+icon bytes on both target platforms.
+
+## Notification capability and permission
+
+The core registers the capability:
+
+```
+verstak/core/notifications/v1
+```
+
+Plugins that use it must both require that capability and declare the
+`notifications.schedule` permission. The plugin-host API exposes only two
+operations within the calling plugin namespace:
+
+```
+api.notifications.replace(items)
+api.notifications.clear()
+```
+
+`replace` is an atomic desired-state replacement, not an append operation. An
+item contains a plugin-local stable `id`, an ISO-8601 UTC `dueAt`, a title, and
+a body. The core supplies the plugin ID and rejects calls from disabled,
+missing-permission, or undeclared-capability plugins. It also validates empty
+IDs, duplicate IDs, invalid timestamps, and unsafe oversized text.
+
+No plugin can send arbitrary immediate native notifications or address another
+plugin's schedules in this alpha.
+
+## Scheduler and persistence
+
+`internal/core/notifications` persists one canonical schedule file at:
+
+```
+<vault>/.verstak/notifications/schedules.json
+```
+
+Each record contains `{pluginId, id, dueAt, title, body, sentForDueAt}`.
+The composite `(pluginId, id)` is unique. Replacing an item with the same due
+time preserves `sentForDueAt`; changing `dueAt` clears it. Replacing a plugin's
+list removes its stale records. This provides deterministic cancellation for
+completed, deleted, and rescheduled Todos.
+
+The manager starts after Wails reaches `OnDomReady`, initializes Wails native
+notifications, and evaluates the persisted schedule immediately and then at
+least every 30 seconds. A sender is injected behind an interface for unit
+tests. After a successful delivery, the manager atomically records
+`sentForDueAt`. A delivery error leaves the schedule pending and is logged for
+a later retry.
+
+An expired record that has not been sent is delivered once after the next app
+start. A record already sent for its current due time is never sent again.
+Completely quitting Verstak stops the scheduler: no separate daemon or OS
+background service is added. Hiding the window in the tray does **not** stop it.
+
+The core calls `CleanupNotifications` during shutdown, including on Linux where
+it releases the D-Bus connection.
+
+## Todo behavior
+
+`verstak.todo` adds the core notifications capability to `requires` and adds
+the `notifications.schedule` permission. After every successful Todo storage
+write, it derives the complete desired reminder list:
+
+- include only open Todos with a valid `reminderAt`;
+- use the Todo ID as the stable notification ID;
+- convert local `datetime-local` input to an ISO-8601 UTC instant;
+- use the Todo title in the notification body and locale-aware reminder text;
+- call `api.notifications.replace` with the full list.
+
+The same replacement runs after loading persisted Todos, so a transient
+schedule-write failure repairs itself next time the Todo view is opened. A
+schedule API failure does not roll back Todo data; the UI reports the failure
+instead. The existing in-view overdue/reminder badge remains useful context and
+is not removed.
+
+## Packaging
+
+`getlantern/systray` requires CGO. The Windows release build already uses
+`x86_64-w64-mingw32-gcc`; the Windows packaging tests must compile it with the
+tray dependency included. Linux build instructions add
+`libayatana-appindicator3-dev`. The Debian package declares the corresponding
+runtime dependency `libayatana-appindicator3-1`.
+
+The existing AppImage packager traverses `ldd` for the desktop executable and
+copies non-glibc runtime libraries. Its verification is extended to prove that
+the appindicator library is present in the AppDir when the tray implementation
+is compiled in.
+
+## Public README and product screenshots
+
+The workspace-root `README.md` and `README.ru.md` supplied by the maintainer
+become the public repository documents: the English source replaces this
+repository's `README.md`, and the Russian source is committed as
+`README.ru.md`. Their existing language links and public-release instructions
+are retained.
+
+Three screenshots are captured from the real desktop application using the
+test vault, then committed under `docs/screenshots/`:
+
+1. `overview.png` — returning to recent work and useful next actions;
+2. `workspace-files-notes.png` — ordinary vault files and Markdown notes in a
+   workspace;
+3. `activity-journal.png` — review of a factual activity session as a Journal
+   entry.
+
+Both README variants include the same three images with localized alt text.
+They are factual UI captures, not generated illustrative mockups. Capture data
+must be limited to the disposable test vault and inspected before commit so no
+credentials or personal content are published.
+
+## Test and manual verification
+
+Automated tests cover:
+
+- schedule replacement, cancellation, rescheduling, persistence, one-time
+  overdue delivery, failed-send retry, and permission/capability rejection;
+- Todo desired-list derivation and calls after create/edit/status/delete;
+- close policy: ordinary close hides, explicit quit permits shutdown;
+- tray controller action wiring and second-instance window reveal;
+- Linux/Windows build scripts and package dependency expectations.
+
+Manual smoke tests are required because neither unit tests nor Playwright can
+assert a real desktop notification area or OS toast:
+
+1. On Linux and Windows, start Verstak, close its window, use the tray menu to
+   reveal it, and use **Quit** to terminate it.
+2. Set a Todo reminder for a near future time, hide the window in the tray, and
+   observe one native notification.
+3. Quit before a future reminder, relaunch after it expires, and observe one
+   overdue notification with no duplicate on the next scheduler scan.
+4. Inspect all three README screenshots at their committed size and confirm
+   that they show only intended test-vault data and explain the feature named
+   in their localized captions.
