stow turns service deployment into a Git-backed control loop. A GitLab repo describes each service; the host reconciles Docker containers to the merged state.
The interesting bit is the boundary. Deployment becomes a normal code review artifact: image digests, config, SOPS-managed secrets, verification, and rollback all belong to the same trail.
Why it belongs here: it makes deployment state explicit, auditable, and repeatable while keeping the operational model small enough to understand.
