Stacks are found from container labels; the file is resolved on the host or through an orchestrator's mounts, and compose runs where the file makes sense (inside Dockhand here), so a redeploy is identical to how the stack was deployed. Save validates with compose and keeps a .hamlab-bak; Deploy / Update / Restart / Stop run as followed tasks. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
