Supply-chain compliance in 2026: what the Cyber Resilience Act's Article 14 duty requires since 11 September 2026 (24-hour early warning, 72-hour notification, ENISA's Single Reporting Platform), what waits until 11 December 2027, how the open-source steward role works, where SBOMs stand (CISA's 2026 minimum elements, CycloneDX 1.7, a 92 percent false-positive rate in a 2,414-repo study), how far provenance has got (SLSA 1.2, 20 percent of PyPI uploads via trusted publishing, Rekor at 3.08 billion entries), the US retreat from mandates, and the pipeline I would run.
13 minOct 5, 2026CI/CD in 2026: Agents Opened 1M PRs in 5 Months, Bots Write 1 in 5 Reviews, and Most Agent PRs Get No Human Look
What the pipeline looks like when AI agents open the pull requests: GitHub's coding agent went GA on 25 September 2025 and opened over a million PRs in five months, Copilot code review passed 60 million reviews and one in five on GitHub, CodeRabbit has reviewed 13 million PRs on $88 million raised, and the first studies find most agent PRs get no human review attention. The gates that still hold: the assigner cannot approve, an extra approval for bot authors, path fences, signed commits, SLSA provenance, and a workflow YAML that gives agent PRs their own lane.
