Three-part consistency defect identified in code review:
1. HTML: Four sidebar elements missing CSS class attributes so all CSS
rules targeting .session-sidebar, .sidebar-toggle-btn,
.sidebar-collapse-btn, and .sidebar-list applied to zero elements.
Added class= attributes to all four.
2. JS: initSidebar(), toggleSidebar(), and bindSidebarClickAway() called
$('sidebar') and $('collapse-btn') — neither ID exists in the DOM.
Corrected to $('session-sidebar') and $('sidebar-collapse-btn').
3. Tests: initSidebar/toggleSidebar mocks matched the wrong IDs, masking
the defect. Updated all six mock conditions to match corrected IDs.
4. Coverage gap: test_html_element_classes did not verify new sidebar
elements carry CSS classes. Added four entries for session-sidebar,
sidebar-toggle-btn, sidebar-collapse-btn, and sidebar-list — these
entries would have caught Defect 1 on Task 1's test run.
All 136 JS + 167 Python tests pass. Zero regressions.
