## ADDED Requirements

### Requirement: Branded Desktop Release Artifacts
The system SHALL provide branded desktop release artifacts for macOS and Windows customers.

#### Scenario: macOS package is built
- **WHEN** the desktop packaging flow runs on macOS for the macOS target
- **THEN** it SHALL produce a TrueGrowth-branded app artifact such as DMG or ZIP
- **AND** the artifact SHALL use TrueGrowth product name, app identifier, version, and icon metadata
- **AND** the app SHALL not require Node.js, pnpm, Vite, or a repo checkout on the customer machine

#### Scenario: Windows package is built
- **WHEN** the desktop packaging flow runs on Windows or a Windows CI runner
- **THEN** it SHALL produce a TrueGrowth-branded Windows installer artifact
- **AND** the artifact SHALL use TrueGrowth product name, app identifier, version, and icon metadata
- **AND** the app SHALL not require Node.js, pnpm, Vite, or a repo checkout on the customer machine

### Requirement: Packaged Renderer and Local API Startup
The packaged desktop app SHALL start from bundled application assets.

#### Scenario: Packaged app starts
- **GIVEN** the app is launched from a packaged install
- **WHEN** Electron creates the main window
- **THEN** it SHALL load the built renderer from bundled files
- **AND** it SHALL start the Local API from bundled scripts
- **AND** it SHALL set packaged-mode runtime paths so writable state is stored outside the read-only app directory

#### Scenario: Development app starts
- **GIVEN** the app is launched by the development command
- **WHEN** a dev server URL is provided
- **THEN** Electron MAY load the renderer from the dev server
- **AND** development behavior SHALL remain available for local debugging

### Requirement: Model Center Owns Optional Runtime Setup
The packaged app SHALL route optional heavy runtime setup through Model Center.

#### Scenario: Heavy dependency is not bundled
- **GIVEN** a customer opens a feature that needs ComfyUI, FunClip, model files, or another heavy local runtime
- **WHEN** the dependency is missing
- **THEN** the app SHALL show a customer-safe setup state that links to Model Center
- **AND** Model Center SHALL offer managed install/download actions or OS-specific guidance
- **AND** the customer SHALL not need technical staff to run repo commands manually

### Requirement: Release Documentation
The project SHALL document repeatable commercial desktop packaging.

#### Scenario: Product owner needs to build a release
- **WHEN** the product owner follows the desktop packaging documentation
- **THEN** the docs SHALL explain prerequisites, commands, output directories, target-platform limits, runtime dependency policy, and signing/notarization steps
- **AND** the docs SHALL distinguish unsigned internal-test artifacts from commercial signed artifacts
