Manual, resumable Docker Sandbox staging smoke: a headless band-sdk LangGraph agent runs inside a real Docker Sandbox (sbx exec) against staging, proving WS receipt + REST reply, and reconnect across three real interruptions (Wi-Fi cycle, host sleep/wake, sandbox daemon restart). probe.py reuses tests/e2e/baseline's pytest-free toolkit (ResourceManager, UserOps, reply_capture) for dynamic per-run agent/room provisioning + reap, instead of a static staging credential or hand-rolled REST/WS calls. skill/SKILL.md lets an AI client (Codex, Claude Code) drive and resume the workflow across the manual checkpoints; a plain operator runs the same scenario by hand via setup.sh/run.sh/probe.py. Both paths share one state.json and produce the same evidence.md. Deliberately not an automated E2E test: a manual, occasionally-run example under examples/, not tests/e2e/. Live-validated against staging in one continuous run (all 4 checks PASS: initial round trip, Wi-Fi reconnect, sleep/wake recovery, daemon-restart recovery via full re-provision). Two real bugs surfaced only by running live, both worked around: band-sdk's git+https:// install fails inside the sandbox (private SSH-only .claude submodule) so agent.py installs from PyPI instead; the sandbox proxy answers CONNECT with HTTP/1.0, which websockets<=15.0.1 rejects and langgraph-sdk pins, so agent.py overrides to websockets>=16.
