# physics-bench-micro

> 120 synthetic physics problems (kinematics, energy, circuits) with programmatically
> verified answers - the estate's first physics benchmark, rights-clean by construction.

## Why synthetic

Every problem is generated and every answer is *computed*, not copied - zero rights
questions, zero contamination from published benchmarks, infinitely regenerable with
a new seed. Synthetic first, then rights-cleared external microbenches (Matbench,
WeatherBench 2) on top, per the leader audit.

## The verification contract

Each row carries explicit `params`; `verify.py` recomputes every answer from them -
a model answer passes only within tolerance. No regex extraction, no ambiguity.

## Honest labels

- **License:** Apache-2.0 (generated by SZL Holdings, no third-party content)
- **Seed:** 20261110 - a new seed produces a fresh, equally valid battery
- **Contamination-proof:** regenerable on demand, so leakage is detectable

*Generated by the estate's benchmark lane; answers machine-verified before publish.*
