September 2025: Strengthened CI/CD and dogfooding across SonarGo and SonarPHP to shorten release cycles and improve build reliability. Delivered unified dogfooding with shadow scans and Iris analysis for SonarGo; increased public CI memory; updated build/scripts and enterprise/public project naming; removed outdated Gradle dependency verification docs to reduce build friction. For SonarPHP, added unified dogfooding workflows with IRIS and shadow scans; aligned project keys/platforms; added licensing scaffolding via package-info.java. Fixed Iris workflow duplication, corrected shadow_scan keys, ensured release bump sequencing, and standardized rule-metadata-update workflow. Upgraded PHP CI/CD to GitHub Release Action v6 and modern runner images. Result: faster feedback, clearer ownership, and stronger cross-repo consistency.
