## Project Overview
### Mission Statement
MetaBuilder is a **declarative, data-driven, multi-tenant application platform** where 95% of functionality is defined through JSON and Lua, not TypeScript. The platform features a 5-level architecture with advanced meta-programming capabilities, functioning as a "platform for building platforms."
### Complexity Classification
**Complex Application** with meta-programming capabilities. Levels 4-5 procedurally generate Levels 1-3 from pure data definitions stored in a modular seed system.
### Core Philosophy
- **Declarative First**: Everything from pages to workflows defined as data
- **Modular**: Clear separation of concerns with isolated, maintainable modules
- **Scalable**: Architecture supports massive applications without unwieldy growth
- **Procedural**: UI and logic generated from configuration, not hardcoded files
---
## Architecture & Design
### 5-Level Architecture
The platform implements a hierarchical level system with progressive access and capabilities:
| Level | Role | Purpose | Access | Key Features |
|-------|------|---------|--------|--------------|
| **L1** | Public | Landing page & login | All users | Public information, login interface |
| **L2** | User | Dashboard & user tools | Authenticated users | Personal dashboard, user settings |
| **L3** | Admin | Admin panel | Admin role users | System administration, user mgmt |
| **L4** | God | Builder & IDE | God role users | Visual page builder, full code access |
| **L5** | SuperGod | Multi-tenant management | SuperGod role | Tenant creation, power transfer, cross-level preview |
### Multi-Tenant System
Complete multi-tenant support implemented with:
- **Tenant Isolation**: Namespace-based data separation for all resources
- **Blob Storage**: Multi-tenant file storage with access control and quotas
- **Structured Data**: User/page/KV/list data scoped to tenants
- **Access Control**: Role-based permissions (owner, admin, member, viewer)
- **Storage Quotas**: Limits on blob storage, record counts, data size, list length
- **Components**:
- `TenantIdentity`: User identity within a tenant
- `TenantQuota`: Resource limits and usage tracking
- `TenantContext`: Context for all operations
- `TenantManager`: Manages tenants, quotas, usage
### Atomic Design Pattern
Components organized into three categories following atomic design principles:
**Atoms** (~12 components)
- Basic UI elements from shadcn/ui
- Buttons, inputs, labels, badges, avatars
- Stateless or minimal state
- Location: `src/components/atoms/`
**Molecules** (~10 components)
- Groups of 2-5 atoms functioning together
- Simple composites with single purpose
- Examples: form fields, search bars, card headers
- Location: `src/components/molecules/`
**Organisms** (~40+ components)
- Complex components forming distinct sections
- May contain business logic
- Examples: data tables, forms, editors, IDE
- Location: `src/components/organisms/`
**Pages/Levels** (5 components)
- Top-level page components (remain at root)
- Level1 through Level5 components
- Location: `src/components/`

### Design Principles
1. **Language Agnostic**: API contracts defined in YAML
2. **Security First**: C++ daemon sandboxes database access
3. **Development Speed**: TypeScript for rapid iteration
4. **Zero Trust**: User code never touches DB credentials
5. **Capability-based**: Adapters declare support (transactions, joins, etc.)
6. **Testable**: Shared test vectors ensure behavioral consistency

- Skeleton, Switch, Slider, Progress, Checkbox, RadioGroup
- And more generic UI primitives
#### Molecules (Simple Composites)
- AppHeader, AppFooter
- GodCredentialsBanner
- ProfileCard
- SecurityWarningDialog, PasswordChangeDialog
#### Organisms (Complex Features)
**Core Builders:**

| AuditLogViewer | 210 LOC | 70 LOC | 66% ↓ |
**Total Violations:** 8 components, 4,146 LOC over limits
### Code Organization Issues
- Components often contain multiple responsibilities
- State management scattered across multiple useState hooks
- Business logic mixed with UI rendering
- Hardcoded configurations in components
- Limited reusability across contexts

- **Coverage**: Target 80%+ for critical paths
- **Performance**: Size limit enforcement

2. Apply schema: `npm run db:push`
3. Run migrations: `npm run db:migrate` (CI/production)
### Seed Data System

- Loaded at application initialization
- Package-based organization for modularity
- Supports multi-tenant data initialization

## Known Issues & Refactoring Needs
### High Priority
#### 1. Component Size Violations
- 8 components exceed 150 LOC architectural limit
- 4,146 total LOC over limits
- **Action**: Systematic refactoring with decomposition strategy
- **Timeline**: 3 weeks, ~103 hours
- **Impact**: Improved modularity, testability, maintainability
#### 2. State Management Scatter
- Business logic scattered across multiple useState hooks
- Duplicated state management patterns
- **Action**: Extract to custom hooks and database persistence
- **Pattern**: One hook per major feature
#### 3. Ephemeral State vs Persistent Data
- Component state lost on page reload
- Should be database-persisted for:
- Editor content (LuaEditor, CodeEditor, SchemaEditor)
- Workflow configurations
- GitHub Actions cache
- **Action**: Implement Prisma models for persistent storage
#### 4. Hardcoded Configurations
- Colors, column definitions, UI configs in components
- **Action**: Move to JSON in database or seed files
- **Benefit**: Runtime changes without code deployment
### Medium Priority
#### 5. GitHub Actions Integration Complexity
- GitHubActionsFetcher: 887 LOC with multiple responsibilities
- Components: API fetching, polling, log aggregation, AI analysis
- **Refactoring Strategy**:
- Create custom hook: `useGitHubActions()` (~50 LOC)
- Separate components for tabs/views (~65-85 LOC each)
- Extract log aggregation to Lua script
- Move analysis cache to Prisma model
#### 6. IDE Implementation Incomplete
- NerdModeIDE: 733 LOC, partial implementation
- Missing: File tree, Git integration, test runner, debugging
- **Strategy**: Componentize into smaller focused modules
#### 7. Lua Editor Missing Features
- LuaEditor: 686 LOC, lacks snippet system integration
- No persistent script storage
- **Action**: Create LuaSnippetLibrary organism, database models
### Low Priority
#### 8. Package System Incomplete
- Pre-built packages not implemented
- Import/export needs UI polish
- Asset handling incomplete
---
## Security Implementation
### Multi-Layer Security Architecture
#### Layer 1: ACL (Access Control Layer)
- **Role-based permissions**: user, admin, god, supergod
- **Operation-level authorization**: create, read, update, delete, list
- **Row-level security**: Users can only access their own data
- **Configuration**: Pre-configured rules for all entities
#### Layer 2: Audit Logging
- **Event Logging**: All operations logged with:
- User context and timestamp
- Operation type and entity
- Input parameters (sensitive data excluded)
- Success/failure status
- Error messages
- **Compliance**: Audit trail for compliance requirements
#### Layer 3: Credential Security
- **SHA-512 Hashing**: All passwords stored as salted hashes
- **Never Plaintext**: Credentials never logged or transmitted
- **Token-based Sessions**: Secure session tokens for API access
#### Layer 4: Input Validation
- **Prisma**: Parameterized queries prevent SQL injection
- **Schema Validation**: JSON schemas enforce data types
- **Lua Sandboxing**: Lua scripts execute in sandboxed environment
#### Layer 5: Error Handling
- **Safe Failures**: Comprehensive error types
- **User-Friendly**: Error messages don't expose internals
- **Logging**: Errors logged for debugging
### Security Policies
#### Password Requirements
- Minimum length enforced
- Hash comparison protected from timing attacks
- Reset tokens with expiration
#### Multi-Tenant Isolation
- Automatic namespace scoping
- Permission checks on all operations
- Quota enforcement per tenant
#### Blob Storage Security
- Namespace-based isolation
- Virtual root directories for path sandboxing
- Size limits and file count limits
#### Future Protections (Phase 3 - C++ Daemon)
- Process isolation
- User code never sees database credentials
- Query validation and sanitization
- Resource limits and quotas
