The author’s own work (all figures in the case studies come from these):

14. OKFExperiment. https://github.com/meabs/OKFExperiment
15. AgentTrialRig. https://github.com/meabs/AgentTrialRig. Release v0.7.0, the first to use the false_pass / false_fail labels: https://github.com/meabs/AgentTrialRig/releases/tag/v0.7.0
16. AgentGraphWorkTree. https://github.com/meabs/AgentGraphWorkTree
17. AgentFrictionLoop. https://github.com/meabs/AgentFrictionLoop
18. “Agent-ready repository design: documentation-layer study” (author’s unpublished document; its figures can’t be independently checked, so the book treats them as lower-grade evidence).
19. Friction Loop assessment report, revision 3, 30 September 2026 (unpublished; superseded in places by the AgentFrictionLoop README, v0.3.0).
20. Agentic Software Engineering: a practical standard, version 1.0, 16 October 2026 (author’s unpublished document).
21. ProgrammingTheLoop-WorkedExample, the worked example that accompanies this book (see “About the evidence”), as of commit b73fe03 (17 October 2026). https://github.com/meabs/ProgrammingTheLoop-WorkedExample. Its agent-trials folder, added in merge commit 1ecf70c, holds the agent trial data for Chapters 3 and 5 (write-up, results tables and per-run transcripts, with environment and host listings redacted before publishing): https://github.com/meabs/ProgrammingTheLoop-WorkedExample/tree/main/agent-trials
