@@ -22,6 +22,7 @@ This repository is a pi provider extension that registers Cursor SDK-backed mode
 - `src/cursor-provider-lazy.ts` owns the lazy `streamSimple` wrapper that defers Cursor provider runtime imports until the provider is invoked.
 - `src/cursor-session-scope.ts` owns pi session cwd, session file/id/name/generation scope keys, and `session_start` / `session_info_changed` registration for session-agent pooling, cloud agent names, and debug grouping.
 - `src/cursor-http1.ts` owns branch-scoped local HTTP/1.1 session state, global-preference override tracking, and extension-owned SDK configuration/null reset.
+- `src/cursor-ripgrep-path.ts` owns bundled Cursor SDK platform ripgrep resolution and local-agent environment initialization.
 - `src/cursor-session-agent.ts` owns session-scoped SDK agent pooling, transport-aware pool identity, send-state commits, busy tracking for in-flight SDK `run.wait()` work, and scoped acquire/dispose state.
 - `src/cursor-session-agent-lifecycle.ts` owns lazy session-agent lifecycle invalidation on model select, compaction, tree navigation, shutdown, and scope changes, including shutdown-time HTTP transport reset before module reload.
 - `src/cursor-session-compaction-prep.ts` owns `prepareCursorSessionForCompaction()` (release scoped live runs, reset pooled agent) wired from `session_before_compact` in `src/index.ts`.
