Unclear What data or feature engineStore actually holds is not stated.

What

Claude Code's per-session state container now allocates a new engineStore, sitting alongside existing per-conversation stores like the cost ledger, hook registry, and model selection. When a session is forked, the new store is inherited from the root session.

Why

This is internal session-state plumbing; the finding doesn't say what the new store is used for.
