 ### Changed
 
+- Container images are now pushed via the `git.schweitz.net` registry endpoint (the `.internal` registry domain is being retired); no change to the image name consumed by Watchtower.
 - `.env.example` service URL defaults now use docker-dataplane container names (`wiki:3000`, `neo4j:7687`, `searxng:8080`, `paperless:8000`, `ollama:11434`) instead of host IP + published port, ahead of the Phase 4 port lockdown; AGENTS.md deploy health-check URL corrected from port 8000 to 8089.
