@@ -63,6 +63,7 @@ Recent decisions affecting current work:
 - [Phase 10-03]: S3 region gets tooltipText only (no helpText) — placeholder is already descriptive
 - [Phase 10-03]: SFTP host and user intentionally omitted from tooltipText — self-explanatory per user decision
 - [Phase 10-03]: getByLabelText selector ambiguity fixed with { selector: 'input' } across all affected tests (same DEBT-01 pattern as Phase 09-03)
+- [Phase 10-content-clarity]: RemoteNamePreview renders only div/span elements (no form controls) to preserve single-textbox selector contract in BackendSelectionStep tests
