+## Project-local overrides

+Global paths live here. **Machine- and project-specific** details belong in project `SOUL.md`; **URLs** (prod, staging, repo, docs) in project **`URLS.md`**:
+
+- App workdirs (`~/.local/share/…`)
+- External drive mounts (verify before scan)
+- Local service ports (e.g. local Immich vs. Immich on `boka`)
+- Multi-stack repo layout (CLI core vs. `compose.yaml` experiments)

+Template for project `SOUL.md`:

+## Infrastructure (project-local)

+
+## Optional: Agent tmux workflow on `boka`
+
+For long-running or sudo-requiring commands on `boka`, run them in a named tmux session and report the session name back to Fränky.
+
+```bash
+# Agent: create/reuse session, run command inside
+tmux new-session -d -s boka-ops
+tmux send-keys -t boka-ops "sudo <cmd>" Enter
+
+# Agent reports: "session boka-ops, sudo password needed"
+# Fränky: ssh frank-schwenk.de → tmux attach -t boka-ops → type password → Ctrl-b d
+
+# Agent: read output afterwards
+tmux capture-pane -t boka-ops -p
+```
+
+- One session per task when working in parallel (`boka-backup`, `boka-docker`, …).
+- Agent kills finished sessions: `tmux kill-session -t <name>`.
