BULKHEAD τ

Stay within the safe envelope defined by the pbc.md charter. Demonstrates real-time contract enforcement and deterministic replay.

Grow asset capital underwriting derivatives. Manage Greeks exposure, wash sale tax harvest limits, and sector concentration boundaries.

Explore US cardiac device market data from Abbott, Boston Scientific, and Medtronic — market share, HHI concentration, and YoY growth across a 253-model published registry. The desk parses its machine-readable charter at runtime and displays the rules beside the analytics they govern.

graphify maps a whole codebase into a force-directed knowledge graph next to the scoped subgraph an AI assistant would actually load for one question. Defaults to mapping graphify itself; switch the picker to see it run against the Ledger (operator-control-plane) or ppr-agent instead.

Phone video of a serve with a sensor/firmware HUD: Zepp handle IMU plus peak edges from STM32 peak-detection under LabWired. Overlay only — not a simulated 3D player. Ball speed after contact.

MediaPipe pose landmarks on the same real serve clip — joints estimated from the footage itself. No sensors, no LabWired, no MuJoCo.

One page, two strokes from the 31-shot session: source clip + MediaPipe pose for each. Serves stay on their own cards. Stroke-mode Zepp has no origin IMU stream (no LabWired peak HUD here).

Same tracked joints as the pose overlay, isolated on an open field instead of drawn over the video — a motion study on its own.

MediaPipe skeleton and the Zepp/LabWired telemetry panel, drawn on the same 90 frames in one pass — not two videos stitched together.

Real wrist tracking marks where the Zepp sensor rides on the serve; beside it, a kernelCAD-designed mount tumbles with the sensor's own measured rotation for this exact swing — not a decorative spin.
