+// Regression test for https://github.com/Zoo-Code-Org/Zoo-Code/issues/634
+//
+// Root cause: getShell() (system prompt) used config.get() which merges all scopes
+// including workspace, while Terminal.getConfiguredDefaultProfileName() used
+// inspect().globalValue — intentionally excluding workspace scope for security.
+// terminal.integrated.defaultProfile.* is APPLICATION-scoped; workspace values are
+// technically accepted by VS Code but ignored by the terminal itself.
+//
+// Fix: getShell() now delegates to Terminal.getConfiguredDefaultProfileName() and
+// Terminal.getConfiguredProfiles(), so both paths read the same inspect()-based values
+// and can never disagree.
+//
+// Run: node_modules/.bin/vitest run integrations/terminal/__tests__/shell-system-prompt-divergence.spec.ts
