The guest portal serves people who interact with the building without being residents — visitors, contractors, couriers, service technicians, short-term occupants. It is a lightweight, no-install surface accessed by link or QR code, with a credential that is scoped, time-bound, and revocable.

A resident invites a guest by issuing a credential through their app. The credential carries a defined window of validity, a specific set of permitted spaces, and an explicit purpose. The guest portal is what the guest sees: arrival instructions, entry credentials, a way to acknowledge house rules, and a single point of contact if something goes wrong. The orchestration engine evaluates the credential at every access point in the same way it evaluates a resident credential — there is no parallel "guest" pathway.

Delivery coordination uses the same primitives. A courier presents a delivery code, the orchestration engine permits scoped entry, and the issue engine routes any exceptions to staff. Temporary credentials for contractors and service technicians follow the same model, with the additional constraint that work-related access is logged against an active service request.
