How does code protect the owner–tenant relationship?

UAGS is unit-centric: a lease is not a static document — it is a lifecycle with durable events. Cross-domain work flows through a unified event channel after data is committed, reducing both operational and legal ambiguity.

Lifecycle (what it means in practice)

• Draft to active: two concurrent active leases on the same unit are blocked; activation creates a clear billing and audit line.
• Renewal: extends dates and version without treating the case as a termination — legally distinct from an end-of-lease.
• Termination: only through a single termination path; financial closure and tenant indicators align to one authoritative end moment.

Owner-facing audit

Authorised phones, eviction notices, and sensitive steps are recorded as events in the chain — every consequential decision leaves a reviewable trace within the operator's permissions.
