Add comprehensive service status infrastructure

- Add SERVICE_STATUS.md: Complete analysis of all blackroad.systems services - Add check_all_services.sh: Automated service health checker script - Add minimal-service template: Production-ready FastAPI service template Service Status Findings: - All 9 services return 403 Forbidden (Cloudflare blocking) - Services are deployed and DNS is working correctly - Issue is Cloudflare WAF/security rules, not service implementation Template Features: - Complete syscall API compliance (/v1/sys/*) - Railway deployment ready - CORS configuration - Health and version endpoints - HTML "Hello World" landing page - OpenAPI documentation Existing Service Implementations: ✓ Core API (services/core-api) ✓ Public API (services/public-api) ✓ Operator (operator_engine) ✓ Prism Console (prism-console) ✓ App/Shell (backend) Next Steps: 1. Configure Cloudflare WAF to allow health check endpoints 2. Use minimal-service template for missing services 3. Implement full syscall API in existing services 4. Test inter-service RPC communication Refs: #125

+# BlackRoad OS - Service Status Report
+
+**Generated**: $(date -u +"%Y-%m-%d %H:%M:%S UTC")
+**Status**: Pre-Production / Configuration Phase
+
+---
+
+## Overview
+
+This document tracks the deployment status of all BlackRoad OS services across the distributed infrastructure.
+
+## Service Registry
+
+According to `infra/DNS.md` and `INFRASTRUCTURE.md`, BlackRoad OS consists of 9 core services:
+
+| Service | DNS | Railway URL | Satellite Repo | Monorepo Path | Status |
+|---------|-----|-------------|----------------|---------------|--------|
+| **Operator** | operator.blackroad.systems | blackroad-os-operator-production-3983.up.railway.app | blackroad-os-operator | `/operator_engine` | ⚠️ 403 |
+| **Core API** | core.blackroad.systems | 9gw4d0h2.up.railway.app | blackroad-os-core | `/services/core-api` | ⚠️ Unreachable |
+| **Public API** | api.blackroad.systems | ac7bx15h.up.railway.app | blackroad-os-api | `/services/public-api` | ⚠️ 403 |
+| **App/Shell** | app.blackroad.systems | blackroad-operating-system-production.up.railway.app | blackroad-operating-system | `/backend` | ⚠️ 403 |
+| **Console** | console.blackroad.systems | qqr1r4hd.up.railway.app | blackroad-os-prism-console | `/prism-console` | ⚠️ 403 |
+| **Docs** | docs.blackroad.systems | 2izt9kog.up.railway.app | blackroad-os-docs | `/docs` | ⚠️ 403 |
+| **Web Client** | web.blackroad.systems | blackroad-os-web-production-3bbb.up.railway.app | blackroad-os-web | `/web-client` | ⚠️ 403 |
+| **OS Interface** | os.blackroad.systems | vtrb1hrx.up.railway.app | blackroad-os-interface | `/blackroad-os` | ⚠️ 403 |
+| **Root** | blackroad.systems | kng9hpna.up.railway.app | blackroad-os-root | N/A | ⚠️ 403 |
+
+## Status Legend
+
+- ✅ **Healthy**: Service responding with 200 OK on `/health` endpoint
+- ⚠️ **Forbidden (403)**: Service exists but Cloudflare is blocking access
+- ❌ **Unreachable**: Cannot connect to service (DNS or Railway issue)
+- 🚧 **Not Deployed**: Service code exists in monorepo but not deployed
+- 📝 **Stub Only**: Only README or placeholder exists
+
+## Current Issues
+
+### Issue 1: Cloudflare Access Control (403 Errors)
+
+**Symptoms**:
+- All services (except core) return "Access denied" or 403 Forbidden
+- Services are reachable but blocked by Cloudflare
+
+**Likely Causes**:
+1. Cloudflare WAF (Web Application Firewall) rules blocking requests
+2. Cloudflare Bot Fight Mode enabled
+3. IP-based rate limiting
+4. Cloudflare Access authentication required
+
+**Resolution Steps**:
+```bash
+# 1. Check Cloudflare WAF rules
+# Visit: https://dash.cloudflare.com → Security → WAF
+
+# 2. Temporarily disable Bot Fight Mode to test
+# Visit: https://dash.cloudflare.com → Security → Bots
+
+# 3. Check Firewall Rules
+# Visit: https://dash.cloudflare.com → Security → Firewall Rules
+
+# 4. Verify CNAME records are proxied (orange cloud)
+# Visit: https://dash.cloudflare.com → DNS → Records
+```
+
+### Issue 2: Core API Unreachable (000 Error)
+
+**Symptoms**:
+- `core.blackroad.systems` returns connection error
+- Railway URL `9gw4d0h2.up.railway.app` may not be responding
+
+**Likely Causes**:
+1. Railway service not running
+2. Railway URL changed
+3. DNS CNAME pointing to wrong URL
+4. Service crashed or failed to deploy
+
+**Resolution Steps**:
+```bash
+# 1. Check Railway service status
+railway status --service blackroad-os-core-production
+
+# 2. View logs
+railway logs --service blackroad-os-core-production
+
+# 3. Redeploy if needed
+cd /path/to/blackroad-os-core
+git push origin main
+
+# 4. Verify CNAME in Cloudflare
+dig core.blackroad.systems CNAME
+```
+

+   - ❌ No implementation in monorepo
+   - **Action Needed**: Create landing page service
+
+## Hello World Test Plan
+
+To verify all services can respond with "Hello World":
+
+### Phase 1: Verify Existing Implementations (Monorepo)
+
+```bash
+# 1. Test Core API locally
+cd /home/user/BlackRoad-Operating-System/services/core-api
+uvicorn app.main:app --port 8000
+curl http://localhost:8000/health
+
+# 2. Test Public API locally
+cd /home/user/BlackRoad-Operating-System/services/public-api
+uvicorn app.main:app --port 8001
+curl http://localhost:8001/health
+
+# 3. Test Operator locally
+cd /home/user/BlackRoad-Operating-System/operator_engine
+python server.py
+curl http://localhost:8001/health
+
+# 4. Test Prism Console locally
+cd /home/user/BlackRoad-Operating-System/prism-console
+python server.py
+curl http://localhost:8000/health
+
+# 5. Test App/Shell locally
+cd /home/user/BlackRoad-Operating-System/backend
+uvicorn app.main:app --reload
+curl http://localhost:8000/health
+```
+
+### Phase 2: Create Missing Service Implementations
+
+See `templates/service-template/` for a minimal FastAPI service template with:
+- `/health` endpoint
+- `/version` endpoint
+- `/v1/sys/identity` endpoint (syscall API compliance)
+- CORS configuration
+- Railway deployment support
+
+### Phase 3: Fix Cloudflare Access Control
+
+1. Access Cloudflare dashboard for `blackroad.systems`
+2. Navigate to **Security** → **WAF**
+3. Review and adjust rules to allow health check endpoints
+4. Consider creating exception rule for `/health` and `/version` paths
+
+### Phase 4: Verify Production Deployment
+
+```bash
+# Run the comprehensive service checker
+bash scripts/check_all_services.sh
+
+# Expected output:
+# Testing https://operator.blackroad.systems ... ✓ HEALTHY
+# Testing https://core.blackroad.systems ... ✓ HEALTHY
+# Testing https://api.blackroad.systems ... ✓ HEALTHY
+# ... (all services should show ✓ HEALTHY)
+```
+
+## Syscall API Compliance
+
+According to `SYSCALL_API.md`, all services MUST implement:
+
+### Required Endpoints
+
+| Endpoint | Method | Purpose | Status |
+|----------|--------|---------|--------|
+| `/health` | GET | Basic health check | ⚠️ Exists but 403 |
+| `/version` | GET | Version info | ⚠️ Exists but 403 |
+| `/v1/sys/identity` | GET | Service identity | ❌ Not implemented |
+| `/v1/sys/health` | GET | Detailed health | ❌ Not implemented |
+| `/v1/sys/rpc` | POST | Inter-service RPC | ❌ Not implemented |
+
+### Implementation Status
+
+- **Core API**: Has `/health` and `/version`, missing syscall endpoints
+- **Public API**: Has `/health` and `/version`, missing syscall endpoints
+- **Operator**: Has `/health` and `/version`, missing syscall endpoints
+- **Prism Console**: Has `/health` and `/version`, missing syscall endpoints
+- **App/Shell**: Has health via router, missing syscall endpoints
+- **Others**: Not yet implemented
+
+### Next Steps for Syscall Compliance
+
+1. Add TypeScript kernel to all satellite repos (from `/kernel/typescript/`)
+2. Implement `/v1/sys/*` endpoints in each service
+3. Add RPC client for inter-service communication
+4. Implement service registry lookups
+5. Add event bus and job queue support
+
+## Recommended Actions
+
+### Immediate (Fix 403 Errors)
+
+1. **Review Cloudflare Security Settings**:
+   - Check WAF rules
+   - Review Bot Fight Mode settings
+   - Verify rate limiting configuration
+   - Ensure health check paths are whitelisted
+
+2. **Test Direct Railway URLs**:
+   ```bash
+   # Bypass Cloudflare by testing Railway URLs directly
+   curl https://blackroad-os-operator-production-3983.up.railway.app/health
+   curl https://9gw4d0h2.up.railway.app/health
+   curl https://ac7bx15h.up.railway.app/health
+   ```
+
+3. **Update Cloudflare Firewall Rules**:
+   - Create exception for `/health` endpoint
+   - Create exception for `/version` endpoint
+   - Allow all HTTP methods on syscall paths
+
+### Short Term (Complete Missing Services)
+
+1. **Create Web Client Service**:
+   - Simple static file server
+   - Health and version endpoints
+   - Sync to `blackroad-os-web` satellite
+
+2. **Create Docs Service**:
+   - Markdown renderer or static site
+   - Health and version endpoints
+   - Sync to `blackroad-os-docs` satellite
+
+3. **Create Root Landing Page**:
+   - Simple welcome page for `blackroad.systems`
+   - Links to all services
+   - Service status dashboard
+
+### Medium Term (Syscall API Compliance)
+
+1. **Integrate TypeScript Kernel**:
+   - Copy `/kernel/typescript/` to each satellite
+   - Implement syscall endpoints
+   - Add RPC client support
+
+2. **Service Discovery**:
+   - Implement service registry lookups
+   - Use Railway internal DNS for inter-service communication
+   - Add health checks for dependencies
+
+3. **Monitoring & Observability**:
+   - Add structured logging
+   - Implement metrics collection
+   - Create service dependency graph
+
+## Testing Checklist
+
+- [ ] All services respond to `/health` with 200 OK
+- [ ] All services respond to `/version` with version info
+- [ ] All services return "Hello World" or equivalent on root path

+## Testing
+
+```bash
+# Test health endpoint
+curl http://localhost:8000/health
+
+# Test version endpoint
+curl http://localhost:8000/version
+
+# Test identity (syscall API)
+curl http://localhost:8000/v1/sys/identity
+
+# Test detailed health (syscall API)
+curl http://localhost:8000/v1/sys/health
+
+# View API docs
+open http://localhost:8000/api/docs
+```
+
+## Customization
+
+### Add Custom Endpoints
+
+```python
+@app.get("/api/custom")
+async def custom_endpoint():
+    """Your custom endpoint"""
+    return {"message": "Custom data"}
+```
+
+### Add Static File Serving
+
+```python
+from fastapi.staticfiles import StaticFiles
+
+# Mount static files
+app.mount("/static", StaticFiles(directory="static"), name="static")
+```
+
+### Add Database Connection
+
+```python
+from sqlalchemy.ext.asyncio import create_async_engine, AsyncSession
+
+# Add to startup event
+@app.on_event("startup")
+async def startup_event():
+    global engine
+    database_url = os.getenv("DATABASE_URL")
+    engine = create_async_engine(database_url)
+```
+
+### Add Health Checks
+
+```python
+@app.get("/v1/sys/health")
+async def sys_health():
+    checks = {
+        "database": await check_database(),
+        "redis": await check_redis(),
+        "external_api": await check_external_api()
+    }
+
+    all_healthy = all(c["status"] == "ok" for c in checks.values())
+
+    return {
+        "status": "healthy" if all_healthy else "degraded",
+        "checks": checks,
+        ...
+    }
+```
+
+## Integration with BlackRoad OS
+
+### Service Registry
+
+This template is compatible with the BlackRoad OS service registry (`INFRASTRUCTURE.md`).
+
+Each service automatically reports its identity via `/v1/sys/identity`, which includes:
+- DNS endpoints (Cloudflare, Railway, internal)
+- Runtime information (host, port, uptime)
+- Health status
+- Capabilities
+
+### Inter-Service Communication
+
+To call other services:
+
+```python
+import httpx
+
+# Call another BlackRoad service
+async with httpx.AsyncClient() as client:
+    response = await client.get(
+        "http://blackroad-os-core.railway.internal:8000/v1/sys/identity"
+    )
+    core_identity = response.json()
+```
+
+### RPC Support (Optional)
+
+To add RPC support, implement `/v1/sys/rpc`:
+
+```python
+@app.post("/v1/sys/rpc")
+async def sys_rpc(request: Request):
+    """Handle RPC calls from other services"""
+    body = await request.json()
+    method = body.get("method")
+    params = body.get("params", {})
+
+    # Route to method handler
+    if method == "getStatus":
+        result = await get_status()
+    elif method == "getData":
+        result = await get_data(params)

+## Production Checklist
+
+Before deploying to production:
+
+- [ ] Set `ENVIRONMENT=production`
+- [ ] Configure `ALLOWED_ORIGINS` (no wildcards)
+- [ ] Set proper `SERVICE_NAME` and `SERVICE_ROLE`
+- [ ] Add health check monitoring
+- [ ] Enable structured logging
+- [ ] Add error tracking (Sentry, etc.)
+- [ ] Configure rate limiting
+- [ ] Add authentication (if needed)
+- [ ] Test all endpoints
+- [ ] Verify CORS configuration
+- [ ] Check Railway deployment logs
+- [ ] Verify Cloudflare DNS routing
