I am an Artificial Intelligence student at Harbin Institute of Technology and founder of SENTARYN, an independent authority layer for AI-generated software changes.

My work focuses on building dependable AI and software systems, with particular interest in agent infrastructure, software authority, developer tooling, security, and human-AI collaboration.

Authority for AI-generated software changes.
Control what AI changes in your software.

SENTARYN evaluates whether an AI-generated software change remained within the authority it was given. It separates repository access from change-specific authority and makes the relationship between intent, scope, evidence, and outcome explicit.

Access is not Authority.

Requested → Authorized → Actual → Evidence → Decision
