+# Telegram Bridge Command Injection E2E Tests
+#
+# Validates that PR #119's fix prevents shell command injection through
+# the Telegram bridge. Tests the runAgentInSandbox() code path by
+# invoking the bridge's message-handling logic directly against a real
+# sandbox, without requiring a live Telegram bot token.
+#
+# Attack surface:
+#   Before the fix, user messages were interpolated into a shell command
+#   string passed over SSH. $(cmd), `cmd`, and ${VAR} expansions inside
+#   user messages would execute in the sandbox, allowing credential
+#   exfiltration and arbitrary code execution.
+#
+# Prerequisites:
+#   - Docker running
+#   - NemoClaw installed and sandbox running (test-full-e2e.sh Phase 0-3)
+#   - NVIDIA_API_KEY set
+#   - openshell on PATH
+#
+# Environment variables:
+#   NEMOCLAW_SANDBOX_NAME  — sandbox name (default: e2e-test)
+#   NVIDIA_API_KEY         — required
+#
+# Usage:
