Gateway Proxy Debug

Use this skill when the wrapper can reach a sandbox but /gateway, HTML injection, WebSockets, or token handoff is broken.

Evidence First

Collect:

• Browser URL and failing request path.
• GET /api/status.
• GET /api/admin/sandbox-diag.
• GET /api/admin/logs filtered for proxy., gateway., sandbox.port_, token..
• Network trace for /gateway/*, WebSocket upgrade, and POST /api/status heartbeat.

Keep app auth, deployment protection bypass, gateway token, and AI Gateway auth separate. Do not paste gateway tokens in artifacts.
