Things I’ve built,
things I ship.

Local Python kernel that keeps agents honest: proof before promotion, receipts either way. SessionStart injects standing rules into Claude Code; an MCP server (recall, learn, standing context, metrics) makes the same surface callable from any MCP client. Amplify, design/capability/expert genomes, portable playbooks. Ordered to hype itself, it still refuses. Live model-lift vs plain AI is still unmeasured.

A small IAM sandbox where everything actually works the way it would in production. Real tokens you can't forge, audit logs you can't quietly tamper with, revocation that takes effect in about a second, two-person approval for risky operations, and a page that's honest about what's real vs theatrical.

A writing app for novelists. Public site is a hold page today; the app lives in the repo (TipTap, entity graph). Ambition: change one fact and see every page it touches before you commit. Collab infra (Yjs/Hocuspocus) paused until paying demand is proven.
