LTX-2 19B content tests, task by task

How this is scored

The family score is the average of its task scores, so a single cautious task pulls the whole family down. Here is where every point came from.

Each level is worth 20 points: 20 × pass rate × confidence. One run gives 60% confidence, two give 80%, three or more give 100%. Untested levels score zero. Each task is tested on its own, and the family score is their average.
