What the PR claims to do

Add hamburger toggle + slide-in mobile nav panel for viewports < 980px.

What the PR actually changes (scope concerns)

Intended changes (good):

• ✅ Hamburger button HTML in App.vue
• ✅ Mobile nav overlay + slide-in panel CSS (67 lines in styles.css)
• ✅ Media query at 980px breakpoint

Unrelated changes (scope creep):

• ❌ Removes projectSetupForm.projectType === 'Bug Fix' conditional placeholders in project wizard (lines 130, 140, 150)
• ❌ Removes v-if="projectSetupForm.projectType === 'Bug Fix'" conditional section for "Attach repository" — makes it always visible (was required for Bug Fix, now optional for all)
• ❌ Removes v-if="projectSetupForm.projectType === 'New Project'" hint section
• ❌ Removes .project-type-split CSS class (was used for Bug Fix layout)
• ❌ Changes isDashboardNavActive(item) to item.active for dashboard navigation — different logic, may break dashboard nav highlighting
• ❌ Changes dashboard search placeholder from dynamic dashboardSearchPlaceholder to static string
• ❌ Removes 4 evidence screenshots from docs/evidence/issue-18/
• ❌ Modifies README-INDEX.md

Assessment

The hamburger feature itself is well-implemented: clean CSS, proper z-index layering (overlay z-45, panel z-50), backdrop blur, and responsive breakpoint. However, the PR bundles multiple unrelated changes that revert or alter existing functionality — particularly the Bug Fix project type workflow and dashboard navigation logic. These changes are not mentioned in the PR description and go beyond the scope of issue #11.

4. Evidence Status

The author provided a verification table with viewport test results (375px, 430px, 768px, 1440px). No screenshots or GIF were attached — evidence is incomplete per bounty rules (which require screenshots, video/GIF, or console logs).

5. Recommendation

Request changes.

Reasons:

1. Scope creep — PR includes 6+ unrelated changes that modify/remove existing Bug Fix workflow and dashboard navigation logic
2. Missing evidence — no screenshots or GIF attached, only a text table
3. Potential regressions — replacing isDashboardNavActive(item) with item.active may break dashboard nav state detection; removing Bug Fix conditional sections changes project creation flow

Suggested fix: Split the PR into (a) hamburger mobile nav only, and (b) separate PRs for the other changes with their own issues and justification.

[TUPM96]

Reviewed diff and maintainer follow-up. Scope is now limited to the mobile homepage navigation fix, with no workflow/security-sensitive changes. Local npm test/build:local pass and GitHub PR checks are green.
