+/**
+ * Autocomplete Value Suggestions E2E Tests
+ *
+ * Tests the new feature that persists field values in IndexedDB and shows them
+ * as autocomplete suggestions when the user types `field =` in the query editor.
+ *
+ * FEATURE DOCUMENTATION:
+ * - Values are captured from: field expansion (sidebar) + search results
+ * - Values are stored in: IndexedDB (o2FieldValues database)
+ * - Values are scoped by: org | streamType | streamName | fieldName
+ * - Values persist across page refreshes
+ *
+ * TEST COVERAGE:
+ * 1. Value capture from field expansion
+ * 2. Value capture from search results
+ * 3. Autocomplete suggestions appear when typing `field =`
+ * 4. Correct quoting behavior (strings vs numbers vs booleans)
+ * 5. Persistence across page refresh
+ * 6. Stream isolation (values don't leak between streams)
+ * 7. Regression - existing autocomplete still works
