+"""shipdeck-bridge — token-gated HTTP wrapper around the shipdeck CLI.
+
+Runs on the DNS2 HOST (not in the container) so that SSH keys, fleet-dns
+credentials and root-level execution stay out of the DashCaddy web container.
+The container reaches it via the docker bridge IP (172.17.0.1), the same
+pattern as the Caddy admin API.
+
+Endpoints (all require X-Shipdeck-Token matching /etc/shipdeck/bridge-token):
+  GET  /api/health                  -> {ok, version}
+  GET  /api/repos                   -> deployable repos (dirs with a Shipdeckfile)
+  GET  /api/services                -> journal-derived service inventory
+  GET  /api/journal?service=N      -> journal rows (newest first)
+  GET  /api/status?service=N       -> live re-probe output
+  POST /api/deploy    {dir}         -> run `shipdeck deploy <dir>` (serialized)
+  POST /api/rollback  {service}     -> run `shipdeck rollback <service>` (serialized)
+  POST /api/install   {repo_url, service, subdomain?} -> GitHub clone+deploy+card (DC-131)
+
+Security model:
+  - Listens on 127.0.0.1:8977 and 172.17.0.1:8977 ONLY (docker bridge + local).
+  - Every request must carry the shared token (0600 file, root-owned).
+  - Deploy dirs are validated: realpath must sit under SHIPDECK_REPOS_ROOT and
+    contain a Shipdeckfile. Service names are strict [a-z0-9-].
+  - The CLI is exec'd via argv lists — never a shell.
+  - Mutations (deploy/rollback) are serialized with a lock; status/journal are
+    concurrent.
