i4h-catheter-navigation-e2e

Invoke the end-to-end skill with a TotalSegmentator subject set in the SUBJ variable. It initializes a timestamped run directory, verifies setup, builds the digital twin into a cache, renders a DRR, runs CPU unit tests, and writes a summary of all artifacts.

Yes, the skill supports a partial path when no subject is provided. It skips the digital twin stage, renders a synthetic DRR instead, still runs setup checks and unit tests, and clearly labels the run as partial in the summary.

No, the end-to-end smoke explicitly skips the interactive viewport because it requires a display. For interactive keyboard-driven demos, use the separate viewport skill after the smoke run completes.

It requires the i4h-workflows repository checked out, host setup requirements from the setup skill, a GPU for cache-based DRR rendering, and an extracted TotalSegmentator subject for the full end-to-end path.

The synthetic fallback triggers when no subject is set or the digital twin stage did not produce a cache. GPU render failures also cause fallback; check the stage logs in the run directory for the specific GPU setup gap.
