steps:
- "Configure the local fake provider with deterministic slow streaming latency."
- "Create or update the LangBot provider, model, and local-agent pipeline that points at the fake provider."
- "Reset the target Debug Chat session."
- "Open concurrent WebSocket Debug Chat connections and send unique deterministic prompts through the real backend pipeline."
checks:
- "automation-result.json status is pass when every request receives its own expected assistant response."
- "metrics_summary shows zero errors under the slow-provider profile."
- "thresholds_summary shows response_p95_ms, first_response_p95_ms, and error_rate pass."
evidence_required:
- metrics
- network
- api_diagnostic
- filesystem
diagnostics:
- "This probe keeps the model deterministic while injecting provider latency, so it catches backend timeout, streaming, and WebSocket backpressure issues without Space variability."
- "Compare with langbot-fake-provider-debug-chat-load to separate fixed LangBot overhead from provider-latency amplification."
success_patterns:
- "Debug Chat WebSocket concurrency probe passed"
- "Streaming completed"
failure_patterns:
- "WebSocket connection error"
- "Timed out after"
- "Final assistant response did not include"
- "All models failed during streaming setup"
