Module session 

Per-session investigation state.

The Model Context Protocol treats each tool call as independent, so any notion of a continuing investigation must be held by the server. This module provides a small, thread-safe store keyed by a caller-supplied session id: follow-up calls that pass the same id see the prior questions and answers, letting the agent build on earlier evidence instead of restarting cold.

The store has no dependency on rig or the corpus engine, so it can be used and tested independently of the MCP layer.
