A browser agent could inspect an incident, compare predefined mitigations, stage one, and attempt execution. The page kept approval visible and blocked the negative path.</p> <p>That proved the shape of the workflow. It did not prove a durable control boundary. The same client state rendered the interface and decided whether execution was allowed. Reloading the page erased the evidence. A stale or competing request had no durable resource version to check. An exact retry could not return a stored result.</p>
