 Rootless Podman quadlets for the offline demo box (`trakrf-demo`). Hosts the
 backend + Timescale + Mosquitto + a Traefik TLS edge, all systemd-managed.
-Design spec: `docs/superpowers/specs/2026-06-07-deploy-edge-design.md`.
+Design specs: `docs/superpowers/specs/2026-06-07-deploy-edge-design.md`,
+`docs/superpowers/specs/2026-06-13-srv-trakrf-runtime-layout-design.md` (TRA-988).
 
 Tim drives the demo from his laptop at **`https://app.demo.trakrf.id`** over the
 Slate WiFi. Break-glass = a shell over the tailnet (`systemctl --user`,
 `journalctl --user -u <svc>`, `podman`).
 
-## Layout
+## Runtime layout — `/srv/trakrf` (TRA-988)
+
+The running stack reads **only** from `/srv/trakrf`, never from this git working
+tree. The repo is the source of truth; `install.sh` deploys it. This means a
+branch switch / pull / `reset` on the checkout can never pull live config out
+from under the services.
+
+```
+/srv/trakrf/
+  quadlets/   *.container, trakrf.network   → symlinked into ~/.config/containers/systemd/
+  config/     mosquitto/mosquitto.conf, traefik/{traefik,dynamic}.yaml
+  scripts/    trakrf-backup.sh
+  systemd/    trakrf-backup.{service,timer}  → symlinked into ~/.config/systemd/user/
+  secrets/    .env  cloudflared.env  mosquitto/passwd  traefik/certs/   (chmod 600; hand-placed; never in git)
+  backups/    trakrf-YYYYMMDD-HHMMSS.sql.gz  (daily pg_dump)
+```
+
+TimescaleDB data stays on the Podman named volume `timescale_data`.
+
+## Repo layout (source of truth)
 
 | Path | What |
 |---|---|
-| `quadlets/*.container`, `*.network` | the 5 services + user network (symlinked into `~/.config/containers/systemd/`) |
-| `install.sh` | symlink quadlets + `systemctl --user daemon-reload` |
+| `quadlets/*.container`, `*.network` | the 5 services + user network (bind-mount from `/srv/trakrf`) |
+| `config/mosquitto/mosquitto.conf` | broker config (plain `:1883`, basic auth) |
+| `config/traefik/{traefik,dynamic}.yaml` | edge static + dynamic config |
+| `scripts/trakrf-backup.sh` | `pg_dump` → `/srv/trakrf/backups` |

+| `install.sh` | deploy `config/`+`quadlets/`+`scripts/`+`systemd/` → `/srv/trakrf`, link + reload units, enable backup timer |
 | `db-init.sh` | one-time DB bootstrap (trakrf schema, search_path, obfuscation key) |
-| `mosquitto/mosquitto.conf` | broker config (plain `:1883`, basic auth) |
-| `traefik/traefik.yaml`, `dynamic.yaml` | edge static + dynamic config |
 | `smoke-test.sh` | broker→subscriber→ingest proof |
-| `.env.example` | template; copy to `.env` (gitignored) and fill |
