Definition

What is Ownership Firewall?

A technical gating layer that validates and sanitizes all incoming data against a master schema before it is committed to the internal lake.
Problem analysis
A. Symptom

Visible Signal

Stripe updates its API, and your revenue dashboard breaks.

B. Business Impact

Consequence

Financial reporting halts until an engineer can "fix" the map.

C. Hidden Failure

Architecture Flaw

Implicit trust of external data providers.

Root cause

The biggest threat to your data is not a hacker; it is a developer at a third-party SaaS company changing a field name. A firewall turns that "Crash" into a "Quarantine".
