Description

Allow researchers to select two or more entities from any table (e.g., zkVMs, Provers, Proofs) and see them side by side in a comparison view. This enables detailed benchmarking and evaluation.

Key Elements to Deliver

• Row selection in all core tables (2–4 entities)
• Side-by-side layout for comparison
• Metrics grouped into clusters (Performance, Security, Auditability, etc.)
• Persistent selection across navigation

Acceptance Criteria

• Users can select 2–4 rows in any table.
• Compare view displays selected entities in a side-by-side layout.
• Core metrics are grouped into logical clusters.
• Comparison persists when navigating between tables.
