HDP-P Gradio Demo v1.0.0

HDP-P + Gemma Physical Safety Demo

Live demo: https://huggingface.co/spaces/helixar-ai/hdp-physical-demo

What is this?

A HuggingFace Gradio Space demonstrating HDP-P (Embodied Delegation Tokens) as a safety layer for LLM-controlled robots.

Gemma (google/gemma-3-12b-it) is the robot brain — it generates every pick-and-place action from natural language.

HDP-P (PreExecutionGuard + signed EdtToken) cryptographically verifies each Gemma output before the arm executes it.

Features

• 2D robot arm simulation with inverse-kinematics-correct animation
• Box loops back and forth: conveyor-in ↔ assembly-cell-4
• Adversarial prompt injection attack demo — HDP-P blocks at class3_prohibited gate
• Live Gemma inference via featherless-ai provider (no model gating required)
• Scripted fallback if HF_TOKEN not set
