Pattern for matching container user UID/GID to mounted volume owner via a gosu-based entrypoint wrapper. Covers UID conflicts (Ubuntu 24.04 ships ubuntu:1000), K8s securityContext compatibility, and alternatives. Learned from agent-runtimes M1 where Claude Code refuses --dangerously-skip-permissions as root. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
