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

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

Key Integration Points

1. DBAL Integration with MetaBuilder

Import pattern:

import { getDBALClient } from '@/lib/dbal-client'

const client = getDBALClient(currentUser, session)

Usage:

// CRUD operations
const user = await client.users.create({ ... })
const users = await client.users.list({ filter: {...} })
await client.users.update(id, {...})
await client.users.delete(id)

2. Component Registration System

Components registered in package catalog with:

• JSON configuration
• Lua scripts for behavior
• Property schema definitions
• UI layout definitions

3. Workflow Engine

Workflows stored as JSON with:

• Node definitions
• Edge connections
• Lua script integration
• Execution context

4. Package System

Each package contains:

• Seed data directory
• Components (JSON + Lua)
• Scripts and utilities
• Static content (assets)
• Manifest with metadata
