+- `Run.SkipRun` applies the `Pester.BeforeContainer.ps1` cascade. Discovery-only runs, which is
+  the path the VS Code Test Explorer uses to populate the tree, went through a batch discovery
+  that never received the setup files. A file whose discovery depends on a folder setup, a
+  `-ForEach` over a variable set in `BeforeDiscovery`, found its cases in a normal run and came
+  back empty in the Test Explorer.
+- `Invoke-Pester` keeps its `-1` exit code when it fails internally. It could overwrite that with
+  `$null` when the failure happened before the run was created, or with `0` when a plugin failed
+  after an otherwise successful run.
