The viewer reads released DSH session formats through v3. It understands embedded assistant streams, system-prompt and request-header updates, correlated retries and commands, compaction, structured context, turn usage/timing, and PTC sub-calls.

It reuses @deepseek-ai/dsh-session, @deepseek-ai/dsh-llm, the published UI primitives and the UI Conversation prompt contracts. Timeline virtualization uses @tanstack/react-virtual, and prompt diffs use diff. Chat and Trajectory projections stay local so the app remains a static client-only viewer with no Cordis runtime or backend bindings.
