BUILDINGData Systems
Structured persistence, access control, and operational data boundaries.
Overview
What this layer means.
Firestore backs inquiry and rate-limit counters today. Client SDK access remains deny-by-default.
Pillars
How we approach it.
Validated writes
Schema validation before persistence.
Least privilege
Admin SDK on the server; rules deny client access by default.
Operational counters
Rate-limit state stored deliberately, not as an afterthought.
Architecture
System flow.
