## Executive Direction (One-Page Summary)

- Keep `letsbe-hub` (Next.js + Prisma) and retool it; do not rewrite core backend in v1 launch window.
- Build Safety Wrapper as OpenClaw plugin + local egress secrets proxy; keep OpenClaw upstream and un-forked.
- Remove all `n8n` and deprecated-stack references as a hard prerequisite (Week 1).
- Replace orchestrator/sysadmin responsibilities with explicit Hub↔Safety APIs and local execution adapters.
- Build mobile app with React Native + Expo for speed, push approvals, and shared TypeScript contracts.
- Use monorepo for first-party LetsBe code (Hub, Mobile, Safety services, Provisioner), while consuming OpenClaw as pinned upstream dependency.
- Target 12-week founding-member launch with strict security quality gates, canary rollout, and staged feature hardening.
