v3.0.1

[3.0.1] - 2026-09-07

The public demo becomes a real feature, and Brain upload stops crying wolf.

Added

• A live public demo. Anyone can now explore Yggdrasil without an account.
  The front page leads with it: one button opens the real platform — the same
  viewers, patients and annotations the research teams use — strictly read-only.
  Nothing can be uploaded, edited or exported from the demo.
• Publishing to the demo is a project decision. A project appears in the
  public demo when the shared guest account is given the Viewer role on it,
  granted on the project page like any other person's access. The project page
  states plainly, for each project, whether it is readable by anyone on the
  internet.

Changed

• The demo opens on the domain chooser instead of dropping visitors into
  whichever domain happened to come first, so a demo spanning several domains
  shows all of them.
• The front page only offers domains you can actually open. Cards for
  domains you hold no project in are no longer shown, and the patient count on
  each card now counts the patients you will actually find behind it.

Fixed

• Uploading a patient in Brain no longer reports a failure that did not
  happen. A successful upload showed a red "Upload failed" message and left
  you on the form, even though the patient had been created; the page now goes
  to the patient list as it does elsewhere. Real upload problems are reported
  with the actual reason instead of a status code.
• Creating a folder in Brain works. It previously failed with a server
  error every time.
• The upload page in Brain no longer errors when no project is selected.
• Access is judged by the project a folder belongs to. Access to one project
  could allow reading, and in some places annotating, a folder belonging to a
  different project while you had the first one open.

Removed

• The per-folder "is demo" checkbox. Demo access is decided by project
  access now. As part of this upgrade the shared guest account's existing
  project access is cleared and must be granted again deliberately, so nothing
  is published to the internet by accident.
