 # Changelog
 
+## [Unreleased]

+### Fixed
+
+- Surface a clear error when the Kilo backend fails to start instead of hanging on loading, write rotated `kilo-dev.log.*` diagnostic logs in release builds, and add CLI install path diagnostics for relocated JetBrains system folders.

 Where to find the log files:
 
 - In sandbox runs, Kilo writes separate dev log files for each side under the IDE sandbox log directory reported by `PathManager.getLogDir()`.
-- Frontend log file: `<sandbox log dir>/kilo-frontend/kilo-dev.log`
-- Backend log file: `<sandbox log dir>/kilo-backend/kilo-dev.log`
+- Frontend log file: `<sandbox log dir>/kilo-frontend/kilo-dev.log.0`
+- Backend log file: `<sandbox log dir>/kilo-backend/kilo-dev.log.0`
 - In practice these sit under the current `log_run*` sandbox logs for the active run.
 - If you are unsure of the exact sandbox root, open the IDE log directory from the running sandbox instance and then look for the `kilo-frontend/` and `kilo-backend/` subdirectories.
