My contribution
Built the server-side calculation service, access model, workbook validation, and quote audit trail.
Tools
FastAPI · Supabase Auth · Server-side workbook data
How it works
- Authenticate the viewer and check an explicit role grant.
- Resolve the selected inputs against a versioned server-side rate table.
- Return the rounded result and version; append a quote audit record.
Decisions that mattered
Keep the rate model on the server
The browser receives only the permitted result, never the private pricing table.
Missing cells remain visible
Two missing workbook cells were identified during validation and surfaced as unavailable rates rather than substituted with invented values.
Access is explicit
User grants, quotas, and audit events make access and use reviewable before a partner rollout.
Results
The October 8, 2026 build record documents an internal-review deployment and validation of the source workbook.
Scope & limits
Partner access hadn’t been released as of October 8, 2026. Rates, quote economics, and partner identity are left out.
