## 3-Node Cluster Quickstart
+The cluster and the Hubble add-on share one named Docker network so Hubble
+can attach to a running cluster without touching it. Treat that network as a
+trust boundary: PD and Store expose unauthenticated control APIs on it (only
+the Server layer authenticates), and any container on the host can join it
+by declaring the well-known name. One-time setup: write the required
+credentials to a mode-600 `docker/.env` and create the network.
+The cluster file requires both credentials — the admin password enables
+authentication, and every Server replica must share one token secret so a
+token issued by any server validates on all of them. The `:?` guards fire
+on every Compose subcommand, including `down`.

+```bash
+(
+ set -eu
+ cd docker
+ command -v openssl >/dev/null 2>&1 || { echo "openssl not found" >&2; exit
1; }
+ [ -e .env ] || install -m 600 /dev/null .env
+ chmod 600 .env
+ # Keep appends on their own lines even if the file was hand-edited.

Review Comment:
Addressed in . The validator now isolates unset and empty admin/token cases,
checks the error names the intended variable, and the setup block validates
existing credentials rather than treating a present-but-empty or short value as
complete. Short token values now fail with a repair message.
