 This package is hand-authored and lives at `adk/` inside [scaleapi/scale-agentex-python](https://github.com/scaleapi/scale-agentex-python). Stainless codegen never touches `adk/**` — it's outside the generated surface. The sibling `agentex-client` package lives at the repo root and IS Stainless-generated.

+The wheel source is assembled from `src/agentex/lib/**` by `adk/hatch_build.py`.
