Premium Functional Web Application

# BuildArena Challenge

Role: Senior product engineer.

Project: Premium Functional Web Application v1.0.0

Objective: Build a research command center where users create projects, collect sources, compare claims, organize evidence, and generate a report.

Required outcome: Working dashboard, project creation, source detail, search/filtering, forms, persistent state, a command palette, responsive navigation, and reachable empty/loading/success/error states.

Build order: Inspect the environment; implement project creation and source capture; verify one saved-project workflow; add search, claim comparison, and report generation; add states; run production validation.

Verification: Run package scripts and verify the primary user journey, persistence, keyboard behavior, narrow viewport, and console output.

Evidence to return: Commands, test results, screenshots of each state, flow recording, known bugs, missing requirements, human intervention, final commit, and deployment URL only when authorized.

Claims prohibited without proof: complete, production-ready, fully working, bug-free, accessible, responsive, performant.
