Awaiting the owner's key
This platform is locked. It opens only with the master password, and that password is defined by the owner himself, on this platform, at first use. No one else holds it, and it is never sent anywhere.
Until the owner's key is set, nothing behind this gate can be seen or changed.
After that, entry is by one-time link only: the owner asks, the team sends a link that works once and closes when he leaves the browser. There is no standing open door.
Administrators: run the platform from its kept standalone package and open this gate in the browser. The first visit offers the owner the setup that defines the master password.
What this platform is
One registry for the whole estate: every subdomain, its pages, and every link its systems generate — page links, download links, book links, session links and group links — reviewable and manageable in one place, and exportable as a single backup file. The registry holds links, subdomains, states and administrator notes only. No sensitive details of people are kept here.
