Title: [Urgent Patch] Addressing Spatial Hallucination & Kinetic Drift in RynnBrain Execution Core #2
Description
Based on a rigorous diagnostic research logic (Exclusion Logic through Hypothetical Perfection), we have identified a structural flaw in the executor.py logic. Under non-ideal conditions (sensor noise/occlusion), the model defaults to semantic guessing rather than geometric verification, leading to "Action Hallucination."
The Defect: The current RynnBrain-Plan lacks a hard-coded geometric constraint layer. It relies on the unified VLA transformer output which can exhibit a spatial offset of >2cm when temporal-visual interleaving is inconsistent.
Proposed Solution (The Safety Gate): We propose a middleware patch to be injected post-inference and pre-RCP execution. This patch enforces a "Geometric Safety Gate" that cross-references the neural output with the raw depth map.
Proposed Code Integration:
Python
def safety_gate(action_sequence, observation):
# Cross-verify predicted Z-axis with real-time Depth Map
# Threshold: 0.005m for drift, 0.02m for E-Stop
# [Insert the provided code snippet here]
Reliability of this Patch: This logic is aligned with the VLA-Safety-Gate principles and ANSI/A3 R15.06-2025
