I provided the builder with a schema and 7 minutes 51 seconds later: Here's its report. It works. Minutes. not days.

All 13 tables are live (2 SOP + 11 schema). Let me do a quick spot-check on the key link fields.
Verify Cases schema
Verify Invoices schema
Everything is wired up correctly. The symmetric link fields were auto-created too — Cases already shows back-links from Leads, Invoices, Case Stage History, Tasks, Documents, and Interactions.
Your relational schema is fully built — 11 linked tables, all FKs wired. Here's the map:

Stage 1 completeness rate — query Stage Quality Metrics where Core Docs Complete = true
Cycle times — Completed At - Started At on Case Stage History
Lead-to-close conversion — Leads status vs. first paid Invoice
Tier upgrade rate — cases with multiple Invoices across service codes
Slice anything by client, year, tier, stage, or team member The Cases table is your 3D hub — every other table points back to it, and the symmetric back-links are already showing.
