Ninja Deprecates Cursor Scoring, Plans Decay Emissions

Ninja is replacing Cursor-based scoring with either single or dual-judge LLM scoring to improve agent quality assessment. A new decay-based emissions system will reward kings based on sustained defense time rather than brief dominance. Task pool rotation launches this week at 10 tasks/hour, with completed task artifacts uploaded to Hugging Face to build a public research corpus.

• •Cursor scoring deprecated due to weak signal; dual-judge LLM scoring under evaluation
• •Decay emissions reward sustained king defense time over total duels won
• •Task rotation begins: 10 oldest tasks removed hourly, artifacts published weekly
• •Task rotation prevents kings from appearing artificially strong on fixed sets
