The Playwright E2E nav suite had two stale assertions failing on chromium-desktop (red since before Memo 088 work): (1) sidebar group check used pixel toBeVisible on lower groups that sit below the headless scroll-fold — switched to toBeAttached (the sidebar genuinely lists all top groups); (2) the 404 check broke on the configured /concepts/tools/ -> /concepts/primitives/ redirect where page.goto returns null — assertion now redirect-safe (real 404s still caught). Hero assertion also updated to the new 'Unified access to any data source' wording. No site change — test-only.
