Sentinel OS: Build-to-Rent Property Platform
2026–PresentA governed operating platform that runs a build-to-rent building end to end. Residents open doors, manage visitors, pay rent, book amenities and complete move-in from one app, while operators run access, leasing, payments and resident services from a single console. Governed access control is live today and the wider platform is in active build, with every action a role-scoped, audited tool, so the platform is ready for Sentinel, an AI agent that does the same work by chat and voice.
- Governed access control and operations shipped on BioStar Air, multi-site, with a real-time event feed, an operator web console, and a resident mobile app
- An MCP gateway that turns every operator and resident action into a governed, role-scoped tool, 47 live today and written to one audit trail
- The full build-to-rent platform in active build: units and buildings, leasing and tenancy, payments and billing, resident verification, amenities, and move-in onboarding
- Sentinel, a governed AI agent over the same tool surface, assisting then acting within guardrails, by chat and then voice
- ArkOS governance throughout: spec-driven development, EARS requirements, and CI-enforced gates against OWASP ASVS, Essential Eight, Privacy Act and WCAG 2.2 AA
