remote-control: Environment expires server-side after ~10 min, no auto-reconnect

Description

claude remote-control sessions disconnect after ~10 minutes with Environment not found error. The server-side environment is expired/cleaned up, causing the local process to shut down with cascading errors. There is no built-in auto-reconnect mechanism.

Steps to reproduce

1. Start remote-control with verbose logging:

``bash
claude remote-control --name 'VCIA' --verbose 2>&1 | tee /tmp/rc-debug.log
``

1. Connect from Claude.ai or the Claude app
2. Complete 1-2 tasks, then wait
3. After ~10 minutes, the session dies

Error output

[20:01:32] Error: Environment env_016keiFKAyiYeESj7P8M7ZHc not found.
[20:01:32] Shutting down 1 active session(s)…
[20:01:32] Session session_01C26MfyGmvLaoRbGNGFAXAT interrupted

[20:01:32] Environment offline.

Investigation

• Not a local resource issue: 5.9 GB RAM available, no swap pressure, no OOM kills
• Bridge WebSocket was healthy: Last successful POST at 20:00:00, no errors in bridge log
• Server-side expiration: The environment ID is deleted/expired by the Anthropic backend
• Reproducible: Happened across multiple sessions (tested with clean system, single Claude instance)

Environment

• Claude Code version: 2.1.72
• OS: Ubuntu 24.04, Linux 6.8.0-101-generic
• RAM: 7.8 GB total
• Node.js: v20+

Suggested improvements

1. Auto-reconnect: When Environment not found is received, automatically re-register and reconnect instead of shutting down
2. Longer TTL: Extend the server-side environment TTL or implement keep-alive pings
3. Graceful degradation: Show "Reconnecting..." instead of cascading error messages

Current workaround

Wrapper script that relaunches remote-control on exit:

#!/bin/bash
NAME="${1:-MyProject}"
MAX_RETRIES="${2:-50}"
COUNT=0

while [ $COUNT -lt $MAX_RETRIES ]; do
    COUNT=$((COUNT + 1))
    echo "[$(date)] Attempt #$COUNT"
    claude remote-control --name "$NAME" --verbose
    echo "[$(date)] Exited. Reconnecting in 5s..."
    sleep 5
done
