This domain is the address space for applications running on Furcate. Each one is served from its own subdomain, by the operator who deployed it, from machines that operator controls. Nothing is served from this address itself.
Most machines that could host something cannot be reached from the internet — a home connection, a small office, anything behind carrier NAT. The usual fix hands your traffic to a company that terminates it. This one does not.
Deploy a site and it is addressed automatically under this domain. No DNS record per application, no configuration at the edge.
Issued on the first request, and stored on the operator's own machine. The private key never leaves the building it was made in.
Public reach comes through a passthrough gateway holding no certificate and no key. It forwards bytes it cannot decrypt, and it is replaceable by changing one record.
Being reachable at a name in a browser is permissioned at four layers — addresses, routing, names and certificates — and no software abolishes that. What can be changed is whether the parts you rent are able to betray you. Here they hold no key, keep no state, and can be swapped in the time a DNS record takes to propagate.
Applications hosted here are treated as belonging to different people, because they usually do. Nothing on this address itself sets cookies, and that is deliberate.
A browser gives each subdomain its own cookie boundary only once a domain is on the Public Suffix List. This one is not on it yet — the submission is pending, and it takes weeks to reach shipped browsers. Until it lands, subdomains here share a cookie scope, which is why the namespace is not yet open for hosting other people's applications. It is listed here rather than omitted because you would have had no way to check.
