The Barkley Reference Architecture is a non-production research demonstrator. It processes only synthetic, locally generated data, makes no network calls, connects to no external service or API, and handles no real, personal, or sensitive data. It is not a deployed system and is not diagnostic.
As such, it has effectively no runtime security surface.
If you nonetheless find a security-relevant issue - for example, an unsafe pattern that could matter if the code were adapted elsewhere - please report it privately to labs@getbarkley.com rather than opening a public issue. Reports will be acknowledged and addressed as the project's solo-maintainer capacity allows.
