Bug RHOAIENG-39116: Remove nested accordion appearance in file explorer

[Gkrumbach07]

Description

Fixed visual nesting issue where file browser sections appeared as nested accordions within the File Explorer and Artifacts accordions.

Problem

The file explorer displayed as a nested one-item accordion, creating poor UX with unnecessary visual nesting. This was caused by border rounded-lg styling on wrapper divs inside the accordion content, which created a visual hierarchy that resembled a nested accordion structure.

Solution

• Removed border and rounded-lg classes from file browser wrapper divs
• Changed border-b to border-y on the header section to maintain visual separation
• Applied fix to both File Explorer and Artifacts accordion sections

Testing

• Frontend builds successfully with no errors
• File tree rendering preserved
• Visual hierarchy simplified without losing functionality
• Section boundaries remain clear with border-y styling

🔵 Minor Issues

1. Consider Visual Regression Testing

• Location: Both changed files
• Issue: This is a visual change without automated tests to prevent regression
• Recommendation: Consider adding a visual snapshot test or at minimum a manual QA checklist
• Impact: Low - the change is simple and easy to verify manually

---

Code Quality Assessment

✅ Follows CLAUDE.md Patterns

Frontend Standards Compliance:

• ✅ Uses Shadcn UI components (Accordion, Button, Badge)
• ✅ Proper TypeScript types (no any types)
• ✅ Component colocated in _components/accordions/ directory
• ✅ Tailwind CSS for styling (consistent with project standards)
• ✅ Clean, focused changes (4 additions, 4 deletions)

Code Structure:

• ✅ Changes are in the right files (UI layer only)
• ✅ No business logic modifications
• ✅ No API/data fetching changes (React Query patterns untouched)
• ✅ Maintains existing component interfaces

---

Security Review

Assessment: ✅ SAFE

This is a pure CSS/styling change with no security implications:

• ✅ No authentication/authorization changes
• ✅ No token handling
• ✅ No data fetching modifications
• ✅ No user input processing changes
• ✅ No RBAC or permission changes

---

Architecture Review

Assessment: ✅ CONSISTENT

Changes follow established frontend patterns:

• ✅ Colocated component in proper directory structure
• ✅ No new dependencies introduced
• ✅ No breaking changes to component interfaces
• ✅ Maintains separation of concerns (UI-only change)

Directory Structure Verification:

components/frontend/src/app/projects/[name]/sessions/[sessionName]/
  ├── page.tsx (main session detail page) ✅
  └── components/
      └── accordions/
          └── artifacts-accordion.tsx ✅

Follows the pattern described in frontend-development.md:

"Keep page-specific components with their pages"

---

Performance Review

Assessment: ✅ NEUTRAL

Performance impact: None

• Removed classes: border, rounded-lg (minimal CSS reduction)
• Added/changed classes: border-b → border-y (neutral)
• No JavaScript changes
• No re-renders introduced
• No new state management

---

Testing Assessment

What Was Tested (per PR description):

• ✅ Frontend builds successfully
• ✅ File tree rendering preserved
• ✅ Visual hierarchy verified
• ✅ Section boundaries maintained

What's Missing:

• ⚠️ No automated test coverage for this visual change
• ⚠️ No visual regression test

Recommendation:
Add to manual QA checklist:

1. Verify File Explorer accordion doesn't appear nested
2. Verify Artifacts accordion doesn't appear nested
3. Verify border-y creates clear visual separation
4. Test on different screen sizes (mobile, tablet, desktop)

Change Analysis

File 1: artifacts-accordion.tsx

-<div className="border rounded-lg overflow-hidden">
+<div className="overflow-hidden">
   {/* Header with breadcrumbs and actions */}
-  <div className="px-2 py-1.5 border-b flex items-center justify-between bg-muted/30">
+  <div className="px-2 py-1.5 border-y flex items-center justify-between bg-muted/30">

Analysis:

• Removed: border rounded-lg from wrapper → eliminates nested accordion appearance
• Changed: border-b → border-y → maintains visual separation with top border
• Kept: All functional classes (overflow-hidden, positioning, spacing)
• Impact: Visual only, no behavioral changes

File 2: page.tsx

Identical pattern applied to File Explorer section (line 1584-1585).

Consistency: ✅ Both file browsers now have identical styling approach.
