MetaBuilder: Functional State Snapshot (2026-01-21)

Overall Status: Phase 2 - 90% Complete, BLOCKED by 13 fixable TypeScript errors

---

🎯 Executive Summary

MetaBuilder is a fully architected, nearly-complete platform with:

• ✅ 3 frontends (Next.js, Qt6, CLI) - all 80%+ complete
• ✅ 56 packages (100% JSON-defined, zero hardcoding)
• ✅ 131+ UI components (fakemui) - complete
• ✅ Full DBAL abstraction layer (TypeScript Phase 2)
• ✅ 326 passing tests (99.7% pass rate)
• ✅ Docker-based deployment (PostgreSQL, Redis, Nginx, monitoring)
• ❌ 13 TypeScript errors blocking build (all fixable, 1-2 hours total)

📊 Frontends Status

Frontend	Status	Purpose	Type
Next.js	90% - Blocked	Main web UI, database-driven routing, JSON component rendering	TypeScript + React 18
Qt6	80% - Active	Desktop marketing/landing page, component preview	QML + Material Design
CLI	70% - Active	Package management, Lua scripting, API access	C++ + Conan + Lua 5.4
DBAL	95% - Hidden	TypeScript abstraction layer (Phase 2)	TypeScript in /dbal/development

Key Architecture: All frontends are bootloaders for the packages system. The database is the source of truth.

🧩 Packages System (56 Total)

Core Packages (12 - Bootstrap Priority)

Phase 1: package_manager (required first)
Phase 2: ui_header, ui_footer, ui_home, ui_auth, ui_login
Phase 3: dashboard
Phase 4: user_manager, role_editor
Phase 5: admin_dialog, database_manager, schema_editor

Optional Packages (44)

• Data: forum_forge, blog, wiki, task_manager
• Utilities: data_table, form_builder, calendar, kanban
• Admin: user_manager, role_editor, audit_log
• Plus 30+ others

Package Structure (100% JSON-Driven)

Each package contains:
├── page-config/         [Routes/pages]
├── component/          [UI definitions]
├── workflow/           [Automation]
├── credential/         [API credentials]
├── notification/       [Alert templates]
├── playwright/         [E2E tests (JSON)]
├── storybook/          [Component stories (JSON)]
└── package.json        [NPM metadata]

Design Principle: Zero hardcoded routes. Everything is database lookups (PageConfig table with god panel overrides).

🧪 Testing Status

Overall: 326 passing, 1 failing (99.7% pass rate)

Test Breakdown

• E2E Tests (Playwright): 126+ tests, all passing
• API Tests: 39 passing, complete coverage
• Auth Tests: 11 passing for getCurrentUser
• Compiler Tests: 9 passing for esbuild integration

Known Failures (3 test files)

1. src/tests/package-integration.test.ts - Cannot import package metadata (missing seed files)

🚀 Deployment Stack

Docker Compose includes (ready-to-deploy):

• PostgreSQL 16
• Redis 7
• Nginx (SSL/TLS, caching)
• Node.js 18 (Next.js app)
• C++ DBAL daemon (if Phase 3)
• C++ Media daemon (FFmpeg, ImageMagick)
• Monitoring stack (optional): Prometheus, Grafana, Loki

Bootstrap Process (7 phases):

1. Wait for database ready
2. Run Prisma migrations
3. Check bootstrap idempotency
4. Load root seed data
5. Install 12 core packages
6. Verify installation
7. Run post-hooks

🔴 Current Blockers (13 TypeScript Errors)

Blocker 1: Type Safety in JSONComponentRenderer (1 error)

File: src/components/JSONComponentRenderer.tsx:23 Issue: Props type too broad (Record<string, unknown>) Fix: Change to Record<string, JsonValue> Time: 2 minutes

Blocker 2: Type Narrowing Lost in page.tsx (2 errors)

File: src/app/page.tsx:65-66 Issue: Casts to unknown lose type info from typeof checks Fix: Add explicit type casts (as string, as JsonValue | undefined) Time: 5 minutes

Blocker 3: Auth Schema Mismatch (4 errors)

Files: fetch-session.ts:44, login.ts:96, register.ts:96, get-current-user.ts:56 Issue: DBAL returns optional fields, return types expect required Fix: Update return interfaces to allow undefined on optional fields Time: 10 minutes (4 files, same pattern)

Blocker 4: Namespace Exported as Component (1 error)

File: src/lib/fakemui-registry.ts:165 Issue: States is { Empty, Loading, Error } namespace, not a component Fix: Replace with 3 individual component entries Time: 5 minutes

Blocker 5: Missing Module Imports (5 errors - test files)

Files: get-current-user.test.ts, package-integration.test.ts, schema/index.ts Issue: Tests reference deleted database modules Fix: Update imports to use DBALClient from @/dbal Time: 15 minutes

Blocker 6: Missing Package Metadata (0 errors, but breaks tests)

Files: admin_dialog/seed/metadata.json, dashboard/seed/metadata.json, etc. Issue: JSON integration test can't import package files Fix: Create empty metadata.json files or fix import paths Time: 10 minutes

📋 Recommended Next Steps

Immediate (Unblock Build)

1. Fix JSONComponentRenderer props type → JsonValue
2. Fix page.tsx type casts → as string, as JsonValue | undefined
3. Fix auth return types → allow undefined
4. Fix fakemui-registry States → 3 individual components
5. Fix test imports → use @/dbal
6. Verify npm run typecheck passes

Short-term (Polish)

1. Create missing package metadata files
2. Fix auth-middleware test (returns 500 vs 401)
3. Run full test suite: npm run test:e2e
4. Verify E2E tests pass

Medium-term (Deploy)

1. Test Docker build: ./deployment/deploy.sh development
2. Verify bootstrap: /deployment/scripts/bootstrap-system.sh
3. Manual smoke test: Navigate to http://localhost:3000
4. Production deployment: ./deployment/deploy.sh production --bootstrap

🎓 Key Architecture Insights

95% Configuration Rule

• UI defined in JSON, not TypeScript
• Business logic in workflows (JSON), not code
• Routes in database (PageConfig), not Next.js router
• Only infrastructure is TypeScript (5%)

Multi-Frontend Design

• Next.js: Web UI bootloader for packages
• Qt6: Desktop/marketing UI bootloader for packages
• CLI: Command-line bootloader for packages
• All 3: Load same packages, same JSON, same routing

Data Flow

Database (PostgreSQL)
  ↓ (DBAL access)
TypeScript DBAL Client
  ↓ (entity operations)
Next.js/Qt6/CLI
  ↓ (JSON loading)
Packages (56 JSON-defined)
  ↓ (component rendering)
Fakemui Registry (131+ components)
  ↓ (React/QML/CLI rendering)
User Interface

Zero Hardcoding

• No hardcoded routes (all in PageConfig)
• No hardcoded components (all in packages)
• No hardcoded permissions (all in database)
• No hardcoded UI (all in JSON)
