executable

$executable

Validates that a file path points to an executable file by checking execute permissions. This is an asynchronous processor that performs a file system access check.

This processor is particularly useful for validating script paths, binary paths, and command executables in configuration files.

Note: This processor performs async file system checks and should usually be used as a validator. Execution permissions are platform-dependent (Unix/Linux/macOS use chmod +x; Windows uses file extensions and ACLs).
