Removes studies/unified-sidebar-wireframe.tsx (1,066 lines) — a design wireframe for TASK-026 (Unified Sidebar). PR #156 shipped the feature; the wireframe is dead code.

Risk: None. File was not imported or referenced anywhere.

Code Review: PR #170 - Remove stale unified-sidebar wireframe study

Summary

This PR removes studies/unified-sidebar-wireframe.tsx (1,065 lines), a design wireframe that is no longer needed after PR #156 shipped the unified sidebar feature (TASK-026).

---

✅ Code Quality & Best Practices

Excellent:

• Clean housekeeping: Removing dead code is essential for maintainability
• Clear commit message: "chore: remove stale unified-sidebar wireframe study" follows conventional commit format
• Well-documented PR: The description clearly explains the context (shipped in Unified Sidebar — Servers, Primitives & Connection Form #156) and risk assessment

Verification:

• ✅ File had no imports or references in the codebase (confirmed via grep)
• ✅ Entire studies/ directory removed (no orphaned files left behind)
• ✅ Clean deletion with no functional impact

---

✅ Potential Bugs or Issues

None identified. This is a pure deletion of unused code with no runtime impact.

---

✅ Performance Considerations

Positive impact:

• Reduces repository size by ~1,065 lines
• Slightly faster clones/checkouts
• Reduces cognitive load for developers navigating the codebase

---

✅ Security Concerns

None. Removing dead code actually improves security posture by reducing the attack surface and eliminating unmaintained code paths.

---

✅ Test Coverage

Not applicable. This file was not imported or executed anywhere, so no test coverage changes are needed.

Recommendation: If you want to be extra thorough, you could verify the build still passes:

pnpm build && pnpm test && pnpm lint && pnpm typecheck

(Per AGENTS.md @rules, this should be run before merging anyway)

---

🎯 Final Recommendation

APPROVE ✅

This is a low-risk, high-value cleanup PR that:

1. Follows repository conventions (AGENTS.md @workflow)
2. Has zero functional impact (verified no references)
3. Improves codebase hygiene
4. Includes clear documentation of why the file is being removed

No changes requested. Safe to merge after CI passes.

---

📝 Minor Suggestions (Optional)

1. Consider a "studies cleanup" issue: If there are other stale wireframes or design studies, you might want to audit the entire studies/ directory pattern periodically.

2. Archive instead of delete (for future reference): If design artifacts have historical value, consider moving to a separate archive/ directory or documenting the wireframe link in the original TASK-026 issue/PR for posterity. However, for a 1k+ line React wireframe with no production value, deletion is the right call.
