When to use this guide
A shared cache serves one customer's human-branded assistant name to another customer's AI support widget.
This is a fictional implementation scenario. The procedure below is Article 50 Hub's suggested working method, not a prescribed legal form, a customer result or a claim that every step is an additional statutory requirement.
Review procedure
-
Create distinct non-sensitive test configurations for two tenants.
-
Load both experiences through the same caching and embedding paths used in production.
-
Check notice wording, locale and participant labels for cross-tenant leakage.
-
Record cache invalidation and fallback behavior after changing one tenant's settings.
What the example review finds
-
Tenant B receives Tenant A's assistant name.
-
A cache refresh changes wording for both tenants.
Keep these example observations separate from your own results. An unknown or untested state should stay open until the relevant evidence has been inspected.

Isolation result
Use the downloadable blank worksheet linked on this page to connect the observed behavior with the deployed system. Add a reviewer, date, evidence reference, unresolved questions and a next action. The worksheet is editable locally and does not upload your records to Article 50 Hub.
Completion and handoff
Close the task only for the scope actually reviewed. Preserve the result that another authorized reviewer can reproduce, identify the owner of remaining work, and record a retest when the implementation changes. A completed worksheet is not a substitute for the underlying evidence.
Decision boundary
This check targets disclosure configuration and is not a complete tenant-security assessment.
The official references below provide legal or technical context. Resolve applicability and exception questions with the responsible qualified reviewer; use the product's tools to organize implementation work within that assessment.
