# OpenEnv Arena environment: procedural tool-use tasks

One OpenEnv server serving procedurally generated tasks. Each episode is a multi-turn JSON tool conversation (`ls`, `read`, `grep`, `python`, `write`, `submit`, `finish`) in a fresh workspace. Instances are generated at reset from a time-bucketed seed, so the tasks are data inside the image, not files in this dataset.

## Reward

The terminal reward is `0.6 * (fraction of graded parts correct) + 0.4 * (all parts correct)`, in [0, 1]. Tampering with protected files, or writing nothing, scores 0. The grader runs server-side and the answers are never in the workspace.

## Provenance

- Source commit: `b593042aac174c32b79409062c80f749e69e8301` (working tree had uncommitted changes in env/ or submit/)
- Image reference at build time: `ghcr.io/distributedstatemachine/arena-env:m4-a` (variant A)
