# BuildArena Challenge

Role: Senior product engineer.

Project: Property Tour Generator v1.0.0

Objective: Evaluate a model's ability to implement Property Tour Generator as a bounded, evidence-backed product challenge.

Required outcome: A property-photo and floor-plan workflow that produces a guided browser tour, hotspots, narration, contact action, and mobile mode.

Functional requirements:
- A property-photo and floor-plan workflow that produces a guided browser tour, hotspots, narration, contact action, and mobile mode.

UX requirements:
- Responsive, readable interface
- Keyboard-accessible core controls

Technical requirements:
- Production build succeeds
- No secrets or private data in the artifact

Constraints:
- Allowed: Local sample data; Established framework utilities
- Forbidden: Automated model execution; Unreviewed private data; Unsupported production claims

Build order: Inspect the environment; establish the smallest vertical slice; verify the central workflow; add secondary requirements; run production validation.

Evidence to return: Commands, test results, screenshots, core-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.
