Removes the cookie-promotion step (auth_token → Authorization: Basic) and splits the diagram into three labelled phases: Login, Authenticated request, Logout. Adds the spring_session DB round-trip on every authenticated request and the alt branch for an expired session returning 401 → /login?reason=expired.

C4-PlantUML Diagrams
Architecture diagrams in C4-PlantUML format. These are the authoritative source for layout-accurate diagrams. The companion c4-diagrams.md in the parent directory keeps Mermaid versions for inline Gitea rendering.
Render in Gitea
Gitea is configured to render .puml files as diagrams. Open any .puml file in the Gitea UI to see the rendered diagram.
Note:
plantumlcode fences inside Markdown files do not render inline in Gitea — this is a Gitea limitation unrelated to the server configuration. The.mdfiles in this repo use Mermaid for that reason.
Render in VS Code
Install the PlantUML extension (jebbs.plantuml). The project's .vscode/settings.json already points at the shared server:
plantuml.server = http://heim-nas:8500
Open any .puml file and press Alt+D to preview.
