| Run admission latency | A run takes about 2.7 seconds to create. | Show a pending state and open the stream immediately. |
| Sandbox session latency | A sandbox-backed session takes about 2.5 seconds to create. | Create sessions before the user needs them when appropriate. |
| Coarse live-bus resync | One publisher failure can resync every subscriber on a session. | Handle stream.resync and replay durable events. |
| Strict tool output schema | One shared schema can reject valid operation-specific results. | Use oneOf or omit fields that do not apply. |
| MCP servers are not dispatched, 4 September 2026 | Agents accept MCP server configuration, but the runtime does not dispatch it. | Use application tools. |
| OpenAPI prose gaps | Some new fields and routes have limited contract examples. | Use these guides with api/openapi/openapi.yaml and the smoke flow. |
| Claim fairness | A stuck older run can delay another tenant. | Use client timeouts and retry only safe requests. |
| Compensation claim race | Two workers can race expired-sandbox cleanup. | Treat cleanup errors as transient and inspect final session state. |
| Admission finalization race | A stale worker can race failure finalization. | Use terminal events as the final client state. |
