The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

HSTS-Enforced blocks all practical TLS stripping attempts while maintaining compatibility for sites that require HTTP - without introducing overhead in the typical case.

C2weakest assumption

That browsers, DNS resolvers, and site operators will correctly implement and use the proposed HTTP-Required indicators (new DNS record and preload list) without widespread misconfiguration or adoption failures.

C3one line summary

HSTS-Enforced flips web security to default HTTPS with explicit HTTP-Required indicators to block TLS stripping while preserving compatibility for sites needing HTTP.
