Admin Access Validation with Tailscale

[perigrin]

User Story

Implement admin access validation using TDD to establish secure administrative
connectivity to the IRC network infrastructure. Write tests that verify successful
Tailscale daemon operation for admin access while validating that service
communication uses Fly.io's private internal network.

Requirements:
- Deploy containers with Tailscale for admin access only
- Validate secure admin SSH connectivity  
- Test network isolation between admin and service traffic
- Establish administrative access testing framework

Expected Output

• tests/test_tailscale_admin.pl - Comprehensive admin access tests (Perl)
• scripts/validate-admin-access.pl - Admin connectivity validation (Perl)
• config/admin-network-policy.yaml - Network isolation configuration
• docs/network-architecture.md - Network design documentation
• scripts/admin-troubleshooting.pl - Admin diagnostic tools (Perl)
• Validated admin access with confirmed service network isolation

Acceptance Criteria

• Write failing tests for admin access validation
• Deploy magnet-9rl container with Tailscale for admin access
• Tests validate Tailscale daemon startup and operation
• Admin SSH access tests pass through Tailscale mesh
• Tailscale status shows successful admin network connection
• Tests verify service traffic uses Fly.io internal network
• Network isolation between admin and service traffic confirmed
• Performance baseline established for admin operations
• Container restart preserves admin access
• Health checks include admin access validation
• All admin connectivity tests pass

Context

This establishes secure administrative access to the IRC network infrastructure using Tailscale while ensuring service communication remains on Fly.io's optimized internal network. Admin access enables secure troubleshooting and management operations.
