  class AuthService:9,76
    func __init__:14,7 -> [_load_secrets]
    func login:22,20  -> [_generate_token, _verify_password]
    func validate_token:43,20
    func _load_secrets:64,12
    func _generate_token:77,4
    func _verify_password:82,3
  func logout:32,8

  import os
  from .services import AuthService

  class App:8,32
    func register_user:15,8
    func place_order:24,15 -> [validate_token, create_order]
  func create_app:4,3
  var VERSION:1

Each symbol shows kind name:start_line,line_count. Container symbols (class/struct/interface) have their children indented underneath. Call relationships appear as -> [callee, ...].
