Shift left — for builders

Eelden's product bet is that multi-tenant isolation, lazy migration, forks, snapshots, CDC, and (eventually) residency / encryption boundaries belong in the database, not in every SaaS codebase.

If you are evaluating the commercial story, start at Business & sales. This page is the short builder view.

What you stop writing

Mental model

1. Tenant = consistency boundary — Tenants, Transactions
2. History is storage — versioned pages; pin with snapshots
3. Cross-tenant is explicit — CDC + sagas, never cross-tenant atomic
4. Meaning is language-layer — schemas, Money, drift as unknown

Honesty

Pre-alpha. Status is authoritative. Diligence table: Capability map. Agent audit: internals/shift-left-audit.md.
