Multi-Environment Script Drift Usually Starts with Copying
Before a routine release, operations lead Xiao Zhou receives what looks like a simple task: run the same service checks in test, pre-production, and production.
There are already three scripts in the shared directory, with filenames ending in test, uat, and prod. But Xiao Zhou does not execute them immediately. The test script contains extra anomaly handling, the production script includes an additional temporary diagnostic command, and the pre-production script still points to an old API address.
The problem is no longer "which environment file should be chosen." It is that nobody can explain why these versions differ. Scripts that were copied originally for quick environment adaptation have gradually turned into three independently evolving execution paths.
