ÆTHERYA Core – deterministic action-governance kernel for LLM agents
Fail-closed policy layer blocks LLM tool calls before execution, no LLM in decision path.

Four-tier stack with algebraic verification feels over-engineered compared to K9 Audit.

Fail-closed policy layer blocks LLM tool calls before execution, no LLM in decision path.
Verifiable decision replay for autonomous systems, but execution complexity limits adoption beyond safety-critical domains.
First public implementation of DeepMind delegation paper. Tested on Zork with governance that blocked 'attack'.
Proposal-first governance + hardware E-stop for AI controlling robots/drones—legitimately novel safety architecture.
Patent portfolio for deterministic AI, but no code, demo, or working system shown.
Mathematically verified policies enforced outside the model—formal proof replaces prompt engineering.
