Kyle Isom 2567d8ab48 Initial CoreDNS setup as MCNS precursor

Serves two internal zones for the Metacircular platform:
- svc.mcp.metacircular.net (service addresses)
- mcp.metacircular.net (node addresses)

Forwards all other queries to 1.1.1.1 and 8.8.8.8. Includes rift
deployment compose with CoreDNS 1.12.1 and zone files mapping
metacrypt and rift to their LAN and Tailscale addresses.

Overview

MCNS precursor — a CoreDNS instance serving internal DNS zones for the Metacircular platform until the full MCNS service is built.

Zones

Zone	Purpose
`svc.mcp.metacircular.net`	Internal service addresses (e.g. `metacrypt.svc.mcp.metacircular.net`)
`mcp.metacircular.net`	Node addresses (e.g. `rift.mcp.metacircular.net`)

Everything else forwards to 1.1.1.1 and 8.8.8.8.

Files

Corefile — CoreDNS configuration
zones/ — Zone files (manually maintained until MCP manages them)
deploy/docker/docker-compose-rift.yml — Docker compose for rift deployment

Operations

# Start
docker compose -f deploy/docker/docker-compose-rift.yml up -d

# Test resolution
dig @192.168.88.181 metacrypt.svc.mcp.metacircular.net
dig @192.168.88.181 rift.mcp.metacircular.net

# After editing zone files, bump the serial and restart
docker compose -f deploy/docker/docker-compose-rift.yml restart

Adding a service

Add an A record to zones/svc.mcp.metacircular.net.zone
Bump the serial number (YYYYMMDDNN format)
Restart CoreDNS

Adding a node

Add an A record to zones/mcp.metacircular.net.zone
Bump the serial number
Restart CoreDNS
