def extract_definition(line)
  # Match constant definitions like:
  #   MAX_SIZE = 100
  #   ALLOWED_TYPES = %w[foo bar].freeze
  #   OPTIONS = { foo: 1 }.freeze
  #
  # Must start with uppercase letter followed by uppercase letters,
  # digits, or underscores, then = (with optional whitespace)
  #
  # Avoid matching:
  #   - Comparisons: MAX_SIZE == 100
  #   - Namespaced access: Foo::BAR
  #   - Class/module definitions

  # First check it's not a comparison
  return nil if line =~ /[!=]=/

  # Match the constant definition pattern
  return nil unless line =~ /^\s*([A-Z][A-Z0-9_]*)\s*=/
