Summary
This host borrows the password and session shape from the login experiment, not that experiment’s accounts, cookies, or database.
Result
Opaque session tokens, hashed passwords, and server-side ownership checks keep one person’s records on this host.
Lesson
Copying login chrome is not sharing identity. Each product owns its session.
