Technology
Correctness first, because ownership records are the product.
A co-ownership platform is only as good as its guarantees. Ours are enforced where they cannot be bypassed: in the database and on the server.

Foundations
What the platform guarantees
Multi-tenant by design
Every tenant-owned record carries its organisation. Row-level security denies by default and is enforced in the database, not in the interface.
Invariants in the schema
Ownership percentages cannot exceed 100%, interests cannot be orphaned, confirmed bookings cannot overlap and oversubscription is rejected at the source.
Server-validated privilege
Transfers, closings, approvals, overrides and payments execute server-side and re-verify the caller's permissions independently of the client.
Exact money
Amounts are stored in integer minor units with an explicit ISO currency. Allocations use largest-remainder distribution so shares reconcile to the cent.
Immutable audit
Membership, ownership, financial, governance and administrative changes append to an audit log that application users cannot edit or delete.
Integrations
Signed outbound webhooks with retries and delivery logs, plus a versioned, scope-limited read API. No universal keys, no blanket table exposure.
Yacht AI
Assistance with boundaries
Permission-scoped tools
The assistant reads only through tools that run under the asking user's own access rights.
Cited document answers
Agreement and policy questions are answered from indexed documents with the source document and section identified.
Propose, review, execute
Consequential manager actions are proposed for confirmation and recorded in the audit trail — never performed silently.
