  * Downstream Triggers:
- * Subscribed to by almost all company-scoped automats, orchestrating their loading

- * - `companyAutomat`, `categoryAutomat`, `brandAutomat`, `unitAutomat`, `posterminalAutomat`
- * - `attributeAutomat`, `propertyAutomat`, `supplierAutomat`, `warehouseAutomat`
- * - `sseAutomat`: Disconnects/reconnects SSE stream to `/api/events` per company
- * - `chatAutomat`: Reconnects AI chat SSE stream and reloads conversations
- * - `articleIndexAutomat`: Resets the derived index on logout; loads it lazily from
- *   the category views once the session is established
- * - `createListAutomat` instances (`deliveryAutomat`, `quoteAutomat`,
- *   `orderAutomat`, `entityAutomat`, `customergroupAutomat`, `numberAutomat`)
- * - Grid history automats (`articleHistoryGridAutomat`, `globalHistoryGridAutomat`)
- * - `artikelAutomat`: Clears cached articles on logout
+ * - With `hasAuth`: SSE (`sseAutomat`) is connected to `/api/events`.
+ * - With `hasAuth && !hasCompany`: `CompanySetupDialog` is shown (`companyAutomat` not instantiated yet).
+ * - With `hasCompany` (requires `hasAuth`): 1st-level menu (`AppShell`) and `companyAutomat`
+ *   are mounted and company APIs are triggered.

-/**
- * ============================================================================
- * Overview of Automats in Dashfront
- * ============================================================================
- *
- * Automats are lightweight, reactive, out-of-tree state containers powered by
- * `react-automat`. They manage all client-side state without React context,
- * hooks, or HOCs, enabling pure, zero-flash rendering in `React.PureComponent`
- * via constructor reads and fine-grained subscriptions.
- *
- * 1. Multi-Tenant Session & Security
- * ----------------------------------------------------------------------------
- * - `authAutomat`: Tracks authenticated session (`user`, `googleClientId`,
- *   `selectedCompanyId`, and auth status `'loading' | 'anon' | 'authed'`).
- *   Coordinates session bootstrap, company switching, and acts as the root
- *   lifecycle trigger that loads or resets all company-scoped automats.
- *
- * 2. Real-Time SSE Hub
- * ----------------------------------------------------------------------------
- * - `sseAutomat`: Manages the single persistent Server-Sent Events connection
- *   (`GET /api/events`). Automatically reconnects when the active company changes
- *   and terminates on logout. Dispatches incoming server mutation signals into
- *   targeted automats (`artikelAutomat`, `articleDetailAutomat`, `categoryAutomat`,
- *   `articleIndexAutomat`, `warehouseAutomat`, `supplierAutomat`, `attributeAutomat`,
- *   `propertyAutomat`).
- *
- * 3. Domain & Entity Caches
- * ----------------------------------------------------------------------------
- * - `artikelAutomat`: In-memory cache for full article records (`GET /api/article/:sku`)
- *   with inflight request deduplication, optimistic renames, and reactive selectors.
- * - `articleDetailAutomat`: Keyed automats (`articleHistoryAutomat`, `articleSupplierAutomat`)
- *   providing per-SKU supplier catalog bindings and change history.
- * - `deliveryEditorAutomat`: Interactive draft state machine for incoming goods receipts
- *   and invoice reconciliation (line items, supplier article auto-matching, PDF/receipt OCR).
- *
- * 4. Company Configuration & Catalogs
- * ----------------------------------------------------------------------------
- * - `companyAutomat`: Active company settings (tax rates, ISO language, root category ID).
- * - `categoryAutomat`: Hierarchical category tree (ID -> node map), mutations (create,
- *   rename, move, reorder, delete), and breadcrumb resolution.
- * - `categoryViewAutomat`: Keyed view container (`categoryViews`) holding articles and child
- *   categories per slug path, auto-preloaded when category tree finishes loading.
- * - `brandAutomat`: Catalog manufacturer and brand records.
- * - `unitAutomat`: Allowed units of measure (Stück, kg, Liter, etc.).
- * - `posterminalAutomat`: Point-of-sale hardware terminals and enabled category filters.
- * - `attributeAutomat`: Product attribute definitions and discrete values (e.g. Size, Color).
- * - `propertyAutomat`: Custom product property and metadata names.
- * - `supplierAutomat`: Directory of vendor entities and supplier article mappings.
- * - `warehouseAutomat`: Warehouse locations and stock storage areas.
- *
- * 5. Company-Scoped List Automats (`createListAutomat`)
- * ----------------------------------------------------------------------------
- * Built with the shared list factory with deduplicated `load()`, silent `reload()`,
- * and automatic synchronization with `authAutomat`:
- * - `deliveryAutomat`: Delivery receipt list (`GET /api/delivery`).
- * - `quoteAutomat`: Sales quotes / Angebote (`GET /api/quote`).
- * - `orderAutomat`: Sales orders / Bestellungen (`GET /api/order`).
- * - `entityAutomat`: Customers and business partners (`GET /api/entity`).
- * - `customergroupAutomat`: Customer discount groups (`GET /api/customergroup`).
- * - `numberAutomat`: Document numbering sequences (`GET /api/number`).
- *
- * 6. Search & Infinite-Scroll Grid Automats
- * ----------------------------------------------------------------------------
- * - `articleIndexAutomat`: Fast client-side search index, **derived** from the loaded
- *   category views (`GET /api/category/:id/articles`) — no dedicated index endpoint.
- * - `articleSearchAutomat`: Client-side search engine querying `articleIndexAutomat`.
- * - `articleHistoryGridAutomat`: Virtualized infinite-scroll grid for article history.
- * - `globalHistoryGridAutomat`: Virtualized infinite-scroll grid for global audit logs.
- *
- * 7. UI State & Utilities
- * ----------------------------------------------------------------------------
- * - `chatAutomat`: AI assistant chat drawer state, conversations, and live SSE streaming tokens.
- * - `navigationAutomat`: Persists last visited delivery document path and article SKU.
- * - `userSettingsAutomat`: User layout preferences (viewer position, drawer widths in IndexedDB).
- * - `helpAutomat`: Interactive help badge states and popper positioning (in IndexedDB).
- * ============================================================================

  * @description Central Server-Sent Events hub managing the single persistent
- * `GET /api/events` connection and fanning mutation signals into domain automats.
+ * `GET /api/events` connection and fanning mutation signals into active automats.
  *
  * Upstream Triggers:
- * - `authAutomat`: Subscribes to auth state changes — reconnects stream when
- *   `selectedCompanyId` changes/becomes available; disconnects on `'anon'` (logout).
+ * - `authAutomat`: Connects stream when `hasAuth` is true (and reconnects when
+ *   `selectedCompanyId` changes); disconnects when `hasAuth` is false (logout).
  *
  * Downstream Triggers:
- * Dispatches real-time SSE mutation events into specific automats:
- * - `artikelAutomat`: Re-fetches article via `reloadArticle(sku)` on `article-<sku>` signals.
- * - `articleDetailAutomat` (`articleHistoryAutomat`, `articleSupplierAutomat`):
- *   Reloads SKU-keyed views on `article-<sku>` signals.
- * - `categoryAutomat`: Triggers `actions.loadTree()` and `invalidateAllCategoryViews()`
- *   on `'category'` SSE events.
- * - `articleIndexAutomat`: Triggers `actions.reload()` on `'articles'` SSE events;
- *   the index is derived from the reloaded category views, so no extra request.
- * - `warehouseAutomat`: Triggers `actions.reload()` on `'warehouse'` SSE events.
- * - `supplierAutomat`: Triggers `actions.reload()` on `'supplier'` SSE events.
- * - `attributeAutomat`: Triggers `actions.load()` on `'attributename'` SSE events.
- * - `propertyAutomat`: Triggers `actions.load()` on `'propertyname'` SSE events.
+ * Dispatches real-time SSE mutation events into active automats without eagerly
+ * importing or instantiating unmounted stores:
+ * - `companyAutomat`: Refreshes warehouses, carriers, attributes, properties,
+ *   suppliers, and brands when `companyAutomat` is active.
+ * - `categoryAutomat`: Refreshes category tree and open category views on `'category'`.
+ * - `articleIndexAutomat`: Refreshes derived article index on `'articles'` / `'warehouse'`.
+ * - `artikelAutomat` & `articleDetailAutomat`: Refreshes watched SKU on `article-<sku>`.
+ * - `orderAutomat`, `quoteAutomat`, `shipmentAutomat`, `deliveryAutomat`, `retoureAutomat`:
+ *   Reloads when those automats are active.
