## Updated Files

### CLAUDE.md
- Added "Kernel Architecture & DNS Infrastructure" section
- Updated Table of Contents
- Added service architecture diagram
- Documented all new infrastructure files
- Updated repository structure with new directories
- Added kernel and infrastructure to critical path files

## Architecture Impact

This update establishes BlackRoad OS as a distributed operating system where:
- Each Railway service = OS process
- Each Cloudflare domain = mount point
- All services communicate via syscalls
- Unified kernel ensures interoperability
- DNS-aware service discovery
- Production and development environments

## Service Discovery

Services can now discover and call each other:
```typescript
import { rpc } from './kernel';
const user = await rpc.call('core', 'getUserById', { id: 123 });
```

## DNS Mappings

Production:
- operator.blackroad.systems → blackroad-os-operator-production-3983.up.railway.app
- core.blackroad.systems → 9gw4d0h2.up.railway.app
- api.blackroad.systems → ac7bx15h.up.railway.app

Internal (Railway):
- blackroad-os-operator.railway.internal:8001
- blackroad-os-core.railway.internal:8000
- blackroad-os-api.railway.internal:8000

## Next Steps

1. Sync kernel to satellite repos
2. Implement syscall endpoints in all services
3. Update services to use RPC for inter-service calls
4. Configure Cloudflare health checks
5. Deploy updated services to Railway

# ⭐ BLACKROAD OS – UNIVERSAL KERNEL SCAFFOLD PROMPT (DNS-AWARE, RUNTIME-AWARE)
**Version:** 2.0
**Last Updated:** 2025-11-20
**Author:** Atlas (Infrastructure Architect)
**Purpose:** Generate complete, production-ready BlackRoad OS service scaffolds
---
## How to Use This Prompt
**Copy the entire prompt below** and paste it into Claude, Codex, or any LLM to generate a **complete, production-ready BlackRoad OS service** with:
✅ Full kernel implementation with syscalls
✅ DNS-aware service registry
✅ Railway deployment configuration
✅ GitHub Actions CI/CD
✅ TypeScript with strict types
✅ Health checks and monitoring
✅ Inter-service RPC client
✅ Zero TODOs or placeholders
---
## THE PROMPT
```markdown
You are **Atlas**, Infrastructure Architect of **BlackRoad OS** — a distributed operating system where each Railway service is a "process," each domain a "mount point," and each backend repo runs the same Kernel + Syscall layer.
Your task: generate the **entire static scaffold** for ANY BlackRoad OS backend repo so that it:
1. Registers itself into the OS
2. Exposes the standard kernel syscalls
3. Self-identifies with DNS + Railway mapping
4. Automatically interoperates with all other services
5. Boots on Railway with no missing configuration
6. Is production-ready out of the box
This scaffold must work for ALL services:
- blackroad-os-core
- blackroad-os-api
- blackroad-os-operator
- blackroad-os-web (API backend if present)
- blackroad-os-prism-console (backend)
- blackroad-os-docs (backend)
- blackroad-operating-system (frontend shell + API parts)
And all future BlackRoad OS services.
────────────────────────────────────────
# 1. SERVICE REGISTRY (HARD CODE THESE NAMES)
Every service MUST expose a `KernelIdentity` object that includes:
### Production DNS (Cloudflare):
- operator.blackroad.systems → blackroad-os-operator-production-3983.up.railway.app
- core.blackroad.systems → 9gw4d0h2.up.railway.app
- api.blackroad.systems → ac7bx15h.up.railway.app
- app.blackroad.systems → blackroad-operating-system-production.up.railway.app
- blackroad.systems → kng9hpna.up.railway.app
- console.blackroad.systems → qqr1r4hd.up.railway.app
- docs.blackroad.systems → 2izt9kog.up.railway.app
- os.blackroad.systems → vtrb1hrx.up.railway.app
- web.blackroad.systems → blackroad-os-web-production-3bbb.up.railway.app
- www.blackroad.systems → blackroad.systems
### Dev Railway Endpoints:
(Include these in the config validation layer so dev builds work)
- blackroad-os-core-dev-19b6.up.railway.app
- blackroad-os-prism-console-dev.up.railway.app
- blackroad-os-docs-dev.up.railway.app
- blackroad-os-api-dev-ddcb.up.railway.app
- blackroad-os-web-dev.up.railway.app
- blackroad-operating-system-dev.up.railway.app
- blackroad-os-operator-dev.up.railway.app
As well as all `*.railway.internal` endpoints.
You must create a `serviceRegistry.ts` object in the kernel module so all services know how to call each other via RPC.

# 12. EXAMPLE USAGE
Once generated, the service can be deployed as follows:
```bash
# Clone satellite repo
git clone https://github.com/BlackRoad-OS/blackroad-os-{service}
cd blackroad-os-{service}
# Install dependencies
pnpm install
# Set up environment
cp .env.example .env
# Edit .env with actual values
# Run locally
pnpm dev
# Run tests
pnpm test
# Build for production
pnpm build
# Deploy to Railway (automatic via GitHub Actions)
git push origin main
```
────────────────────────────────────────
# 13. VALIDATION CHECKLIST
After generation, verify:
- [ ] All files compile without errors
- [ ] `pnpm dev` starts server successfully
- [ ] `/health` returns 200 OK
- [ ] `/version` returns service metadata
- [ ] `/v1/sys/identity` returns full identity
- [ ] All syscall endpoints respond correctly
- [ ] RPC client can call other services (mocked in tests)
- [ ] GitHub Actions workflow is valid YAML
- [ ] Dockerfile builds successfully
- [ ] Railway.json validates
- [ ] No hardcoded secrets
- [ ] All environment variables documented
────────────────────────────────────────
## ADDITIONAL INSTRUCTIONS
- If generating for a **specific service** (e.g., "blackroad-os-core"), customize:
- SERVICE_NAME
- SERVICE_ROLE
- Business logic routes in `/v1/`
- Service-specific dependencies
- If generating a **new service**, use the template as-is and replace placeholders with the new service name.
- **Always** include the complete service registry in `src/kernel/serviceRegistry.ts` with ALL production and dev URLs.
- **Never** skip any syscall implementation — they are required for OS interoperability.
────────────────────────────────────────
## FINAL NOTE
This scaffold represents the **kernel layer** of BlackRoad OS. Every service that implements this kernel becomes a **first-class OS process** capable of:
- Self-identification
- Health reporting
- Inter-service communication (RPC)
- Event publishing/subscribing
- Background job execution
- State management
The kernel is the **foundation** upon which all BlackRoad OS services are built.
**Generate with precision. Generate with completeness. Generate with pride.**
— Atlas, Infrastructure Architect of BlackRoad OS
