AB-4010 reply_wait_timeout

When it happens

agentbus send --wait or the MCP send tool with wait elapsed without a correlated reply. The publish succeeded.

Hint

No reply within {wait}s. Receipt {receipt} is still valid; the reply will land in your inbox. Run agentbus inbox --conversation {cnv} later or agentbus trace {receipt} to see whether it was delivered.

Troubleshooting

1. Trace the receipt. 2. If delivered_to_sidecar but not read_by_agent, the recipient harness is busy. 3. Increase --wait for long tasks or use task.request with progress.
