# Tera source boundary

Arena is public Apache-2.0 environment work. Tera is Lumbridge's proprietary
world simulator and is developed in the private `lumbridge-private/tera`
repository.

The `tera_spatial` bridge and `tera-crow-nav` taskset were previously committed
to Arena. Those historical revisions remain available under the license granted
when they were published; deleting current files does not revoke that grant or
rewrite git history. As of 2026-08-25, maintained bridge code, vendored simulator
closures, Tera tasksets, and new Tera releases live only with private Tera.

The boundary is about source ownership, not rebuilding upstream machinery:

- Arena and private Tera both depend on Prime Intellect Verifiers for the
  environment/harness contract.
- Forge delegates training to Prime-RL across a subprocess boundary.
- No Lumbridge repository should implement its own generic rollout harness,
  trainer, environment hub, or GPU marketplace.
- Publishing an Arena environment to Prime Hub is a separate owner-approved
  action. Nothing in this repository publishes automatically.
