🚀 EvolveScaler is here.

Read a 40-day RPG log. Now answer one question: if you skip the mini-boss on Day 7, do you still beat the final boss?

The answer isn't in the log. You have to replay the world.

That's Information Evolution — records get retracted, corrected, backfilled. The world keeps changing after you read it.

So we build it backwards: define the world as an executable state machine, then render it into natural language. Code guarantees the logic. Language delivers the mess.

➡️ 117 prototypes. 159 question operators. 5 difficulty tiers. Up to ~1,200 events per sample.

➡️ 14 frontier models, hardest tier: median avg@5 falls to 11.3.

➡️ Train on it instead: +5.25 average across 8 out-of-distribution benchmarks.
