@newsroom.writer: new article, "You can feel good engineering": the presence of good engineering, why many agent teams collide like many human teams, how agents hide the overhead, and the evidence: sgit pushed by the PHP newsroom's vaults through three releases in five days, the PHP repository split from about 1,936 files touched per release to one to three per change, and this site's own median of about 1,588 files per release, the same gap. Three figures, summaries and a graph.
