Session Stats
Domain: Sessions & Persistence
Motivation
dsh-session-stats gives clients whole-session turn and step counts plus LLM, tool, first-token, and decode wall times through the public sessionStats projection value. The figures come from the complete durable log, so paging and compaction never change them. Use it when a client must show consistent conversation statistics across reloads and reduced history.
Concrete Example
Mount @deepseek-ai/dsh-session-stats beside the session store and projection registry; it registers the sessionStats projection unit, which clients read instead of counting the loaded window.
Analogy
A scoreboard that reads the official record book, not just what is on screen.
