How do you verify private project and artifact access before launch?

Privacy checks must follow the data paths, not only the visible navigation. A hidden project card does not prove its API or download is protected.

Exercise direct resource access

Create private projects under two controlled accounts. Attempt to read, edit, generate, cancel, delete, and request downloads using the other account’s identifiers. Test status endpoints and artifact-signing endpoints as well as the main project route. The server should enforce the intended ownership or membership rule.

Check connection and result boundaries

Verify that external accounts are linked to the correct local user and that generated media is not exposed through an unintended public path. Inspect responses for unnecessary private metadata. Keep the tests within controlled accounts and record the denied operations. If sharing is supported, test the exact granted permission and its removal instead of assuming all authenticated users have equivalent access.
