                  class DeadLetter < ApplicationRecord
  validates :job_class, :payload, :error_class, presence: true
end

                  class SafeJob < ApplicationJob
  rescue_from(StandardError) do |error|
    DeadLetter.create!(
      job_class: self.class.name,
      payload: arguments,
      error_class: error.class.name,
      error_message: error.message
    )
    raise
  end
end

Retries can become infinite noise. For certain failure classes, record the payload + error in a DLQ table and alert/triage. This keeps queues healthy and makes failures actionable.
