The release process changed from team to team: hand-carried packages, configuration drifting between test and production, the classic "works on my machine" surprises, go-lives with no rollback plan. Where risk accumulated could not be measured, because the pipeline itself was not standard; every go-live day felt less like a planned task and more like a stressful event.

We redesigned the line: no package moves past static analysis, dependency and security scans; one signed artifact travels unchanged through dev, test, preprod and prod; environments are defined as code, so they cannot drift. Rollback is a planned step of the pipeline, not the exception.
