Canary limitations

A warrant canary is a transparency mechanism. It does not guarantee the absolute absence of surveillance, but publicly signals service integrity at a given moment. Failure to renew beyond the expiry date should be interpreted as a warning signal.

Independence and sovereignty

Koperateur Consulting operates a sovereign, auditable infrastructure with no dependency on any uncontrolled third party. The canary complements this model by providing a continuous, verifiable integrity declaration.
