+# Brev launchable startup script — CI-Ready CPU
+#
+# Pre-bakes a VM with everything needed for NemoClaw E2E tests so that
+# CI runs only need to: rsync branch code → npm ci → nemoclaw onboard → test.
+#
+# What this installs:
+#   1. Docker (docker.io) — enabled and running
+#   2. Node.js 22 (nodesource)
+#   3. OpenShell CLI binary (pinned release)
+#   4. NemoClaw repo cloned with npm deps installed and TS plugin built
+#   5. Docker images pre-pulled (sandbox-base, openshell/cluster, node:22-slim)
+#
+# What this does NOT install (intentionally):
+#   - code-server (not needed for automated CI)
+#   - VS Code themes/extensions
+#   - NVIDIA Container Toolkit (see brev-launchable-ci-gpu.sh for GPU flavor)
+#   - Ollama / vLLM
+#
+# Readiness detection:
+#   Writes /var/run/nemoclaw-launchable-ready when complete.
+#   Also writes "=== Ready ===" to /tmp/launch-plugin.log for backward compat.
+#
+# Usage (Brev launchable startup script — one-liner that curls this):
+#   curl -fsSL https://raw.githubusercontent.com/NVIDIA/NemoClaw/<ref>/scripts/brev-launchable-ci-cpu.sh | bash
+#
