execution-pipeline

Trace the end-to-end notebook execution pipeline from MCP tool invocation through the daemon and kernel to identify where cells fail to execute. This workflow pinpoints timing gaps, missing outputs, and required_heads gating issues causing run failures.

Missing or delayed outputs during a Run All Cells workflow occur due to runtime state desynchronization or kernel lifecycle coordination issues. Tracing execution via RuntimeStateDoc polling resolves output manifests and detects stale results across the pipeline.

RuntimeStateDoc polling resolves inconsistent notebook execution results by continuously tracking runtime state across the daemon and kernel. This coordinates kernel lifecycle events and output resolution to correct stale outputs and synchronize execution flows.

Yes, you can trace required_heads gating issues when notebook cells fail to execute. The end-to-end execution pipeline diagnostics track these gating dependencies through the daemon to identify blocking conditions preventing cell execution.

The best way to diagnose timing gaps in end-to-end notebook execution is tracing the MCP invocation path through the daemon and kernel. This pipeline diagnostics approach detects delays, stale results, and missing output manifests.
