# initialDirConfig - **valid initialDir with restriction adds to allowedPaths** – verifies that a provided initial directory is normalized and added to `allowedPaths` when `restrictWorkingDirectory` is true. - **valid initialDir without restriction leaves allowedPaths unchanged** – ensures the path is normalized but not appended when restrictions are disabled. - **invalid initialDir logs warning and is undefined** – an invalid path triggers a warning and the setting becomes `undefined`. - **initialDir omitted results in undefined** – confirms the default when no `initialDir` is specified. - **non-string initialDir preserved when null without warning** – a `null` value remains in the configuration and does not trigger a warning.
