wedfrgt/dsh-workspace-sync

Cross-device DSH session sharing across Windows and macOS: sessions stay grouped under the same portable workspace on every machine, the git repository never contains a machine-specific path, and sync behaviour is configured in a runtime-live settings page. Workspace identity is explicit (workspaceId + name in the repo, local path only on the machine that owns it); adopted sessions get their header cwd rewritten as a byte-surgical first-frame edit that leaves the rest of the log untouched; deletion propagation is bounded so a peer can never remove a session you created.
