readable

$readable

Validates that a file or directory path exists and has read permissions for the current process. Performs an asynchronous file system access check.

This processor uses Node.js fs.access() with R_OK flag to verify read permissions without actually opening the file. Note that permission checks can be subject to race conditions where permissions change between validation and actual file access.

(e.g., "/etc/hosts", "./config.json", "~/Documents")
