feat(mobile/nav): add a short transition

The prepareMigrations() function called MIGRATIONS.sort() which mutated
the module-level exported array. When the test setup ran migrations via
beforeAll(), the array was left in ascending order, causing the
migrations.spec.ts ordering test to fail.

 ### Test Organization
 - **Server tests** (`apps/server/spec/`): Must run sequentially (shared database state)
 - **Client tests** (`apps/client/src/`): Can run in parallel
-- **E2E tests** (`apps/server-e2e/`): Use Playwright for integration testing
+- **E2E tests** (`packages/trilium-e2e/`): Shared Playwright tests, run via `pnpm --filter server e2e` or `pnpm --filter client-standalone e2e`
 - **ETAPI tests** (`apps/server/spec/etapi/`): External API contract tests
 
 **Pattern**: When adding new API endpoints, add tests in `spec/etapi/` following existing patterns (see `search.spec.ts`).

-### Monorepo Structure
-- **apps/**: Runnable applications
-  - `client/` - Frontend application (shared by server and desktop)
-  - `server/` - Node.js server with web interface
-  - `desktop/` - Electron desktop application
-  - `web-clipper/` - Browser extension for saving web content
-  - Additional tools: `db-compare`, `dump-db`, `edit-docs`
+**Running a single test file**: `pnpm --filter server test spec/etapi/search.spec.ts`
 
-- **packages/**: Shared libraries
-  - `commons/` - Shared interfaces and utilities
-  - `ckeditor5/` - Custom rich text editor with Trilium-specific plugins
-  - `codemirror/` - Code editor customizations
-  - `highlightjs/` - Syntax highlighting
-  - Custom CKEditor plugins: `ckeditor5-admonition`, `ckeditor5-footnotes`, `ckeditor5-math`, `ckeditor5-mermaid`
+## Main Applications
 
-### Core Architecture Patterns
+The four main apps share `packages/trilium-core/` for business logic but differ in runtime:
 
-#### Three-Layer Cache System
-- **Becca** (Backend Cache): Server-side entity cache (`apps/server/src/becca/`)
-- **Froca** (Frontend Cache): Client-side mirror of backend data (`apps/client/src/services/froca.ts`)
-- **Shaca** (Share Cache): Optimized cache for shared/published notes (`apps/server/src/share/`)
+- **client** (`apps/client/`): Preact frontend with jQuery widget system. Shared UI layer used by both server and desktop.
+- **server** (`apps/server/`): Node.js backend (Express, better-sqlite3). Serves the client and provides REST/WebSocket APIs.
+- **desktop** (`apps/desktop/`): Electron wrapper around server + client, running both in a single process.
+- **standalone** (`apps/client-standalone/` + `apps/standalone-desktop/`): Runs the entire stack in the browser — server logic compiled to WASM via sql.js, executed in a service worker. No Node.js dependency at runtime.
 
-#### Entity System
-Core entities are defined in `apps/server/src/becca/entities/`:
-- `BNote` - Notes with content and metadata
-- `BBranch` - Hierarchical relationships between notes (allows multiple parents)
-- `BAttribute` - Key-value metadata attached to notes
-- `BRevision` - Note version history
-- `BOption` - Application configuration
+## Monorepo Structure
 
-#### Widget-Based UI
-Frontend uses a widget system (`apps/client/src/widgets/`):
-- `BasicWidget` - Base class for all UI components
-- `NoteContextAwareWidget` - Widgets that respond to note changes
-- `RightPanelWidget` - Widgets displayed in the right panel

+
+## Core Architecture
+
+### Three-Layer Cache System
+
+All data access goes through cache layers — never bypass with direct DB queries:
+
+- **Becca** (`packages/trilium-core/src/becca/`): Server-side entity cache. Access via `becca.notes[noteId]`.
+- **Froca** (`apps/client/src/services/froca.ts`): Client-side mirror synced via WebSocket. Access via `froca.getNote()`.
+- **Shaca** (`apps/server/src/share/`): Optimized cache for shared/published notes.
+
+**Critical**: Always use cache methods, not direct DB writes. Cache methods create `EntityChange` records needed for synchronization.
+
+### Entity System
+
+Core entities live in `packages/trilium-core/src/becca/entities/` (not `apps/server/`):
+
+- `BNote` — Notes with content and metadata
+- `BBranch` — Multi-parent tree relationships (cloning supported)
+- `BAttribute` — Key-value metadata (labels and relations)
+- `BRevision` — Version history
+- `BOption` — Application configuration
+- `BBlob` — Binary content storage
+
+Entities extend `AbstractBeccaEntity<T>` with built-in change tracking, hash generation, and date management.
+
+### Entity Change & Sync Protocol
+
+Every entity modification creates an `EntityChange` record driving sync:
+1. Login with HMAC authentication (document secret + timestamp)
+2. Push changes → Pull changes → Push again (conflict resolution)
+3. Content hash verification with retry loop
+
+Sync services: `packages/trilium-core/src/services/sync.ts`, `syncMutexService`, `syncUpdateService`.
+
+### Widget-Based UI
+
+Frontend widgets in `apps/client/src/widgets/`:
+- `BasicWidget` / `TypedBasicWidget` — Base classes (jQuery `this.$widget` for DOM)
+- `NoteContextAwareWidget` — Responds to note changes
+- `RightPanelWidget` — Sidebar widgets with position ordering
 - Type-specific widgets in `type_widgets/` directory
 
+**Widget lifecycle**: `doRenderBody()` for initial render, `refreshWithNote()` for note changes, `entitiesReloadedEvent({loadResults})` for entity updates. Uses jQuery — don't mix React patterns.
+
 #### Reusable Preact Components
 Common UI components are available in `apps/client/src/widgets/react/` — prefer reusing these over creating custom implementations:
 - `NoItems` - Empty state placeholder with icon and message (use for "no results", "too many items", error states)
@@ -77,42 +131,48 @@ Common UI components are available in `apps/client/src/widgets/react/` — prefe
 - `Checkbox`, `RadioButton` - Form controls
 - `CollapsibleSection` - Expandable content sections
 
-#### API Architecture
-- **Internal API**: REST endpoints in `apps/server/src/routes/api/`
-- **ETAPI**: External API for third-party integrations (`apps/server/src/etapi/`)
-- **WebSocket**: Real-time synchronization (`apps/server/src/services/ws.ts`)
+Fluent builder pattern: `.child()`, `.class()`, `.css()` chaining with position-based ordering.
 
-### Key Files for Understanding Architecture
+### API Architecture
 
-1. **Application Entry Points**:
-   - `apps/server/src/main.ts` - Server startup
-   - `apps/client/src/desktop.ts` - Client initialization
+- **Internal API** (`apps/server/src/routes/api/`): REST endpoints, trusts frontend
+- **ETAPI** (`apps/server/src/etapi/`): External API with basic auth tokens — maintain backwards compatibility
+- **WebSocket** (`apps/server/src/services/ws.ts`): Real-time sync
 
-2. **Core Services**:
-   - `apps/server/src/becca/becca.ts` - Backend data management
-   - `apps/client/src/services/froca.ts` - Frontend data synchronization
-   - `apps/server/src/services/backend_script_api.ts` - Scripting API
+### Platform Abstraction
 
-3. **Database Schema**:
-   - `apps/server/src/assets/db/schema.sql` - Core database structure
+`packages/trilium-core/src/services/platform.ts` defines `PlatformProvider` interface with implementations in `apps/desktop/`, `apps/server/`, and `apps/client-standalone/`. Singleton via `initPlatform()`/`getPlatform()`.
 
-4. **Configuration**:
-   - `package.json` - Project dependencies and scripts
+**PlatformProvider** provides:
+- `crash(message)` — Platform-specific fatal error handling
+- `getEnv(key)` — Environment variable access (server/desktop use `process.env`, standalone maps URL query params like `?safeMode` → `TRILIUM_SAFE_MODE`)
+- `isElectron`, `isMac`, `isWindows` — Platform detection flags
 
-## Note Types and Features
+**Critical rules for `trilium-core`**:
+- **No `process.env` in core** — use `getPlatform().getEnv()` instead (not available in standalone/browser)
+- **No `import path from "path"` in core** — Node's `path` module is externalized in browser builds. Use `packages/trilium-core/src/services/utils/path.ts` for `extname()`/`basename()` equivalents
+- **No Node.js built-in modules in core** — core runs in both Node.js and the browser (standalone). Use platform-agnostic alternatives or platform providers
+- **Platform detection via functions** — `isElectron()`, `isMac()`, `isWindows()` from `utils/index.ts` are functions (not constants) that call `getPlatform()`. They can only be called after `initializeCore()`, not at module top-level. If used in static definitions, wrap in a closure: `value: () => isWindows() ? "0.9" : "1.0"`
+- **Barrel import caution** — `import { x } from "@triliumnext/core"` loads ALL core exports. Early-loading modules like `config.ts` should import specific subpaths (e.g. `@triliumnext/core/src/services/utils/index`) to avoid circular dependencies or initialization ordering issues
+- **Electron IPC** — In desktop mode, client API calls use Electron IPC (not HTTP). The IPC handler in `apps/server/src/routes/electron.ts` must be registered via `utils.isElectron` from the **server's** utils (which correctly checks `process.versions["electron"]`), not from core's utils
 
-Trilium supports multiple note types, each with specialized widgets:
-- **Text**: Rich text with CKEditor5 (markdown import/export)
-- **Code**: Syntax-highlighted code editing with CodeMirror
-- **File**: Binary file attachments
-- **Image**: Image display with editing capabilities
-- **Canvas**: Drawing/diagramming with Excalidraw
-- **Mermaid**: Diagram generation
-- **Relation Map**: Visual note relationship mapping
-- **Web View**: Embedded web pages
-- **Doc/Book**: Hierarchical documentation structure
+### Binary Utilities
 
-## Development Guidelines
+Use utilities from `packages/trilium-core/src/services/utils/binary.ts` for string/buffer conversions instead of manual `TextEncoder`/`TextDecoder` or `Buffer.from()` calls:
+
+- **`wrapStringOrBuffer(input)`** — Converts `string` to `Uint8Array`, returns `Uint8Array` unchanged. Use when a function expects `Uint8Array` but receives `string | Uint8Array`.
+- **`unwrapStringOrBuffer(input)`** — Converts `Uint8Array` to `string`, returns `string` unchanged. Use when a function expects `string` but receives `string | Uint8Array`.
+- **`encodeBase64(input)`** / **`decodeBase64(input)`** — Base64 encoding/decoding that works in both Node.js and browser.
+- **`encodeUtf8(string)`** / **`decodeUtf8(buffer)`** — UTF-8 encoding/decoding.
+
+Import via `import { binary_utils } from "@triliumnext/core"` or directly from the module.
+
+### Database
+
+SQLite via `better-sqlite3`. SQL abstraction in `packages/trilium-core/src/services/sql/` with `DatabaseProvider` interface, prepared statement caching, and transaction support.
+
+- Schema: `apps/server/src/assets/db/schema.sql`
+- Migrations: `apps/server/src/migrations/YYMMDD_HHMM__description.sql`

-### Security Considerations
-- Per-note encryption with granular protected sessions
-- CSRF protection for API endpoints
-- OpenID and TOTP authentication support
-- Sanitization of user-generated content
+Three inheritance mechanisms:
+1. **Standard**: `note.getInheritableAttributes()` walks parent tree
+2. **Child prefix**: `child:label` on parent copies to children
+3. **Template relation**: `#template=noteNoteId` includes template's inheritable attributes
 
+### Attribute Inheritance

-## Common Development Tasks
+## Important Patterns
 
-### Adding New Note Types
-1. Create widget in `apps/client/src/widgets/type_widgets/`
-2. Register in `apps/client/src/services/note_types.ts`
-3. Add backend handling in `apps/server/src/services/notes.ts`
+- **Protected notes**: Check `note.isContentAvailable()` before accessing content; use `note.getTitleOrProtected()` for safe title access
+- **Long operations**: Use `TaskContext` for progress reporting via WebSocket
+- **Event system** (`packages/trilium-core/src/services/events.ts`): Events emitted in order (notes → branches → attributes) during load for referential integrity
+- **Search**: Expression-based, scoring happens in-memory — cannot add SQL-level LIMIT/OFFSET without losing scoring
+- **Widget cleanup**: Unsubscribe from events in `cleanup()`/`doDestroy()` to prevent memory leaks
 
-### Extending Search
-- Search expressions handled in `apps/server/src/services/search/`
-- Add new search operators in search context files
+## Code Style
 
-### Custom CKEditor Plugins
-- Create new package in `packages/` following existing plugin structure
-- Register in `packages/ckeditor5/src/plugins.ts`
+- 4-space indentation, semicolons always required
+- Double quotes (enforced by format config)
+- Max line length: 100 characters
+- Unix line endings
+- Import sorting via `eslint-plugin-simple-import-sort`
+
+## Testing
+
+- **Server tests** (`apps/server/spec/`): Vitest, must run sequentially (shared DB), forks pool, max 6 workers
+- **Client tests** (`apps/client/src/`): Vitest with happy-dom environment, can run in parallel
+- **E2E tests** (`packages/trilium-e2e/`): Shared Playwright tests, run via `pnpm --filter server e2e` or `pnpm --filter client-standalone e2e`
+- **ETAPI tests** (`apps/server/spec/etapi/`): External API contract tests
+
+## Documentation
+
+- `docs/Script API/` — Auto-generated, never edit directly
+- `docs/User Guide/` — Edit via `pnpm edit-docs:edit-docs`, not manually
+- `docs/Developer Guide/` and `docs/Release Notes/` — Safe for direct Markdown editing
+
+## Key Entry Points
+
+- `apps/server/src/main.ts` — Server startup
+- `apps/client/src/desktop.ts` — Client initialization
+- `packages/trilium-core/src/becca/becca.ts` — Backend data management
+- `apps/client/src/services/froca.ts` — Frontend cache
+- `apps/server/src/routes/routes.ts` — API route registration
+- `packages/trilium-core/src/services/sql/sql.ts` — Database abstraction
 
 ### Adding Hidden System Notes
 The hidden subtree (`_hidden`) contains system notes with predictable IDs (prefixed with `_`). Defined in `apps/server/src/services/hidden_subtree.ts` via the `HiddenSubtreeItem` interface from `@triliumnext/commons`.
