The previous note scoped the single-file bind-mount staleness bug to Docker Desktop only. It actually affects ALL platforms including native Linux: Docker bind-mounts the inode, not the path. Editors that do atomic save (vim, nvim, VS Code, sed -i) create a new inode via rename(), leaving the container pinned to the old unlinked one. This is a kernel limitation (moby/moby#15793, open since 2015, unfixable). Rewrite both the README.md caveat and the docker-compose.yml inline note to describe the real mechanism (inode replacement), name the affected editors, note that append-only writes are safe, and link to the upstream issue.
