+# .claude/ — Harness-Config fürs Multi-Agent-System
+
+`settings.json` ist **committed** (team-weit): jede Leader- wie Worker-Session in
+diesem Repo bekommt dieselben Permissions. Persönliche Abweichungen gehören in
+`settings.local.json` (gitignored).
+
+## Was die Permissions tun
+- **`defaultMode: acceptEdits`** — Datei-Edits/Writes laufen ohne Prompt (Worker
+  schreiben Code in ihrem Paket frei). Ownership-Verstöße fängt das Ownership-Gate
+  beim Commit, nicht der Prompt.
+- **allow** — die Gate-Skripte, git read+workflow (inkl. `git worktree`), `bash -n`,
+  `pytest`, `dvc`, `ollama`, `curl` (Gitea-API für PRs) und gängige Read-Utils.
+- **deny** — `git push --force`/`-f`, `git clean -fd(x)`, `sudo rm`, katastrophale
+  `rm -rf /`/`~`. Hart blockiert, nicht nur Prompt. Alles übrige (z. B. ein
+  einzelnes `git reset --hard`) ist *nicht* allow-gelistet → es fragt nach.
+
+## Parallel arbeiten mit tmux + git worktree (empfohlen)
+Ein Worker pro Paket in **eigenem Worktree + eigener tmux-Pane** — so kollidiert
+nichts, und das Ownership-Gate hält die Grenzen sauber:
+
+```bash
+# je Worker einen Worktree auf seinem Branch
+git worktree add ../$(basename "$PWD")-W2 -b feat/w2-profiles main
+git worktree add ../$(basename "$PWD")-W3 -b feat/w3-exporter  main
+# … dann in je einer tmux-Pane:
+cd ../<repo>-W2 && claude     # Inhalt von session-prompts/W2.md einfügen
+```
+
+Der **Leader** bleibt im Haupt-Checkout (Branch `main`/`integrate/*` → vom
+Ownership-Gate ausgenommen), integriert die Worker-PRs und löst Konflikte.
+Nach dem Mergen: `git worktree remove ../<repo>-W2`.
+
+> Optional global (persönlich, nicht hier): `teammateMode: "tmux"` in
+> `~/.claude/settings.json`, falls du Claudes native Teammate-Spawns nutzt.
