Joshua Johosky

Founder and CEO of Oak and Sparrow Systems Enterprise, building Gatekeeper, a deterministic pre-execution governance layer for AI agents. Gatekeeper sits between an AI system and its intended action, evaluates the action against a formally encoded ontology of statutes, and returns a byte-deterministic verdict sealed in a cryptographic artifact chain. Refusal is the default state. Execution requires proof. No language models in the enforcement layer. Background spans systems architecture across distributed logistics and skilled trades, with a decade-plus of shipping production systems into regulated environments. Interests run across information geometry, comparative philosophy, theology, and the epistemic foundations of decision-making under uncertainty. The through-line is the same question in every domain: what does it take to know that a system is behaving the way you think it is, before you find out the hard way that it isn't.
