Property workflows as state machines, payments and e-signing built in.

Real estate transactions are state machines. Listing → under offer → exchanged → completed. Tenancy → applied → referenced → signed → active → terminated. Archiet detects these from your PRD and generates enforced transitions at the database layer (migrations include CHECK constraints) and in the API (guarded transition endpoints).

Tenant and landlord data is PII. Archiet's DPIA populates from the entity model, enumerates lawful bases, data retention per record type (leases typically 6 years, credit-check results typically 2), and third-party processor tracking for every integrated vendor.

Stripe Connect for escrow / marketplace-style payment splits (agent fees, tenant deposits, landlord payouts). DocuSign-compatible e-signing patterns for leases and transfer documents. Document generation templates that produce the paperwork as PDF for signature.
