A plain index of software and technical work, separate from the XP desktop UI, so it remains easy to read and easy to index.

A cognitive-governance kernel that makes AI agents show their work before they act. Before any high-impact action (git push, deploy, migration), a deterministic hook requires the agent to commit its reasoning to disk — knowns, unknowns, assumptions, and a falsifiable disconfirmation — and refuses to proceed until the artifact is real. Verified lessons become hash-chained, context-scoped protocols that resurface at the next matching decision, so the agent gets sharper on your codebase over time. Ships as a Claude Code plugin and a Python kernel with a vendor-neutral adapter layer.
