Local-first fraud and risk tooling, with honesty-first defaults: fail-closed paths, stubs labeled as stubs, and Downstream owning enforcement.
- tarka — open-source local-first fraud OS (compose desk, evaluate, cases, agent)
- opencv-care-ladder — agentic senior-care escalation ladder (OpenCV AI Competition 2026)
- do-my-chore — Flutter + Supabase family chore / savings POC
- mohawk — study / drill desk for the fraud-workbench family (Rust + FSRS)
- one-crew — desk agent with required picks and a floor that never posts
- night-desk — HOLD or ESCALATE night ops desk (never close money)
- ContextGuard — DataHub schema-change guard
- hermes-fraud-intel — small fraud intel cron
- shadow — local-first desktop workbench (distinct from internal shadow_agent)
The portfolio signature is honesty engineering: what is live, what is a stub, and what Downstream must still decide.
