workflows-orchestration

Black-Tortoise is an enterprise-grade starter kit pursuing "extreme decoupling" and "strong consistency." We follow the Occam's Razor principle: do not multiply entities beyond necessity. Every line of code must justify its existence, and every architectural layer must strictly observe its boundaries.

1. Core Contexts

• [Account Module](src/app/account/README.md) - Manages User, Organization, and authorization.
• [Workspace Context](src/app/workspace/README.md) - Logical boundary for all business capabilities.

2. Capabilities

• [Capabilitys Overview](src/app/capabilitys/README.md) - Includes 12 independent modules such as Tasks, Documents, QC, Calendar, etc.

3. Foundations

• [Architecture Governance](.github/instructions/61-architectural-governance-copilot-instructions.md) - CI-level DDD and Event-Sourcing enforcement mechanism.
• [Audit Capability](docs/AUDIT_CAPABILITY_DEV_GUIDE.md) - Audit capability development guide and quality standards.
• [Eventing System](src/app/eventing/README.md) - Purely reactive event bus and storage design.

1. Strict Layered Boundaries (DDD Layers)

• Presentation: Pure view and Signals data binding. EventStore access is forbidden.
• Application: Use case orchestration and state management (NgRx Signals Stores).
• Domain: Pure business logic, entities, and value objects. Zero framework dependencies.
• Infrastructure: Technical implementation (Firebase, HTTP, external SDKs).

2. Event-Driven Communication

• Inter-module communication is only allowed via events.
• Follow Append-Before-Publish: persist to EventStore first, then publish to EventBus.

3. Zero-Config Backend

• Seamless initialization based on GCP ADC and Firebase.
• Supports AI-driven automated audit and architecture guard.

4. Pure Reactive & Modern Control Flow

• Pure Reactive: The system fully adopts Angular Signals. Observables are limited to the Infrastructure layer and converted to Signals at the Application boundary. Achieves zone-less change detection for better performance and predictability.
• Modern Control Flow: Completely abandons legacy structural directives (ngIf, ngFor). Uses Angular 18/20 standard @if, @for, @switch, and @defer syntax for intuitive, efficient, and better-typed code.

Black Tortoise (玄武) is one of the Four Symbols in Chinese tradition, symbolizing the north, winter, and the water element. Its image is a combination of a tortoise and a snake, representing:

• Stability & Longevity: This project aims to build an enterprise system that stands the test of time—stable and robust.
• Ultimate Defense: Strict DDD boundaries, Dependency Cruiser, and architecture guards protect core business logic from external technology changes.
• Purity & Inclusiveness: The tortoise's solidity and the snake's agility together drive the "purely reactive" power system.

Requirements

• Node.js 22+
• pnpm 9+

Installation & Startup

```bash

# Install dependencies

pnpm install

# Start development server

pnpm run start

# Run architecture gate (CI sync)

pnpm run architecture:gate

```

---

We use [Playwright](playwright.config.ts) for UI testing and [dependency-cruiser](scripts/dependency-cruiser.cjs) for static architecture validation.

See each module's AGENTS.md and README.md for details.
