# Sidebar-First Navigation Refactor Review

## Outcome
Approved.

## Success Criteria Validation
- [x] No top navbar/subnav is rendered in the final dashboard layout.
  - Verified `DashboardLayout` no longer imports/renders `TopBar` or `SubNav` (`src/components/DashboardLayout.tsx`).
- [x] Sidebar contains the five required recruiter-facing nav labels under a `Navigation` subheader.
  - Verified labels: `Overview`, `Projects`, `Experience`, `Education`, `Skills` under `SectionTitle` = `Navigation` (`src/components/Sidebar.tsx`).
- [x] Expanded sidebar includes a distinct `My Data` area above `Navigation`.
  - Verified `My Data` section is rendered before Navigation in expanded mode (`src/components/Sidebar.tsx`).
- [x] Sidebar scrolling no longer exposes hidden top spacing/artifacts when scrolling upward.
  - Verified old top/subnav offset coupling removed from layout flow; main content is now a full-height flex region with sidebar-driven structure (`src/components/DashboardLayout.tsx`, `src/index.css`).
- [x] Desktop navigation from sidebar correctly jumps/scrolls to each section.
  - Verified `onNavigate` targets `data-tile-id` anchors and uses smooth `scrollIntoView` (`src/components/DashboardLayout.tsx`, `src/components/Sidebar.tsx`).
- [x] On mobile, sidebar is collapsed by default with hamburger at top and five icon shortcuts visible.
  - Verified mobile defaults to collapsed (`isMobileExpanded=false`) and renders hamburger + icon-only nav rail (`src/components/Sidebar.tsx`).
- [x] On mobile expand, sidebar shows `My Data`, full navigation links (icon + text), and tags/alerts/highlights.
  - Verified expanded mode conditionally renders all required blocks (`src/components/Sidebar.tsx`).
- [x] Navigation controls are keyboard accessible with appropriate ARIA semantics.
  - Verified interactive controls are native buttons, include `aria-expanded`, `aria-controls`, `aria-label`, and `aria-current`, plus focus-visible styling (`src/components/Sidebar.tsx`, `src/index.css`).
- [x] `npm run lint` passes.
  - Passes with 2 pre-existing warnings only (`react-refresh/only-export-components` in context files).
- [x] `npm run typecheck` passes.
- [x] `npm run build` passes.

## Validation Commands
- `npm run lint`
- `npm run typecheck`
- `npm run build`

## Notes
- Build emits existing non-blocking warnings for large chunks and `onnxruntime-web` eval usage; no blocking errors.
