The runtime substrate for meta-agents over LLM agent execution, evaluated in the accompanying paper. This is the exact version used for all experiments in ../exp/, frozen at the experiment/submission snapshot (post-submission changes to the upstream library are intentionally excluded).

Build

The repository root is a uv workspace. From the repository root:

uv sync

resolves the substrate packages here and the experiment subprojects in ../exp/ against them, with no dependency on any external package index for the substrate itself.
