What it is
Bezier heart path beating at 72 BPM with a scrolling EKG strip beneath. Two-pump physiology in the animation (systole/diastole double-thump).
Renders as a face on the CONDUIT dashboard and standalone. The most intimate UI element in the suite: it visibly represents the operator's continued aliveness.
Where it sits
VITALS is catalogued under Biometric & Embodied in the instrument registry. Instruments in this group share a concern and are frequently composed rather than used alone; the related entries below are the nearest ones.
This is a registry entry: a real instrument, documented here, without a public endpoint a stranger can open. Pages carrying source excerpts and measured results are marked as such in the catalog. If you want detail on this one specifically, ask about it directly.
