How to read the collection

01

Prefix value

Every partial point is the arithmetic mean of 32 normalized rubric grades from fresh continuations of that exact response prefix. It is not a binary success probability.

02

Trajectory endpoint

The diamond is the original base response's continuous rubric grade. The downstream PRM dataset separately thresholds eligible endpoints at 0.5 for a hard yes/no label.

03

Empty prefix

Each problem contributes two selected base traces, so its empty prefix appears once per trace in the raw branch set. The 86,156 rows correspond to 80,929 unique semantic problem-prefix inputs.

04

PRM filtering

The downstream training build removes duplicate empty prefixes, invalid endpoints, and overlength prompts while preserving provenance counts.
