Concepts

These pages explain behavior and boundaries that a user can observe across the CLI, Python, VS Code, Cursor, and the browser viewer.

• Sessions and viewer lifetime explains launch ownership, progressive discovery, logical navigation, temporary frame reuse, and shutdown.
• Ephemeral state and network security explains the access token on every API request, what it does not protect, and what disappears at shutdown or can be deliberately exported.
• DICOM and pixel support describes renderable, metadata-only, and controlled-unsupported states, the presentation pipeline, real-world values, and known limits for v0.4.1.
• Semantic objects and WSI explains stored-pixel preview, conservative declared context, SEG and colorwash overlays, and positioned-tile limits.

For procedures, use the guides. For exact supported commands, settings, and formats, use the reference. Contributors can find implementation architecture and debugging surfaces under Contributing.
