chore(infra): add missing LICENSE files to publishable packages (#39146) `langchain-core` and a few other packages under `libs/` build their PyPI sdists without a LICENSE file, so downstream redistributors have to supply their own copy (the conda-forge `langchain-core` feedstock, for example, keeps a manual `recipe/LICENSE` as a workaround). Packages like `langchain-classic` and `langchain-anthropic` already ship the license correctly because they have a `LICENSE` file in the package directory that hatchling picks up by default. This brings the remaining packages in line with that pattern by copying the repo-root MIT `LICENSE` (verified byte-identical to the existing `libs/langchain/LICENSE`) into the four package directories that lacked one: - `langchain-core` - `langchain-model-profiles` - `langchain-tests` (standard-tests) - `langchain-text-splitters` No `pyproject.toml` or build-config changes were needed — hatchling includes a root-level `LICENSE` in the sdist automatically once the file exists. All other package dirs (both `langchain` packages and every `libs/partners/*`) already have one and were left untouched. Verified by building each sdist with `uv build --sdist` and confirming the file is in the tarball: - `langchain_core-1.5.3.tar.gz` → `langchain_core-1.5.3/LICENSE` - `langchain_model_profiles-0.0.6.tar.gz` → `langchain_model_profiles-0.0.6/LICENSE` - `langchain_tests-1.1.9.tar.gz` → `langchain_tests-1.1.9/LICENSE` - `langchain_text_splitters-1.1.2.tar.gz` → `langchain_text_splitters-1.1.2/LICENSE` ## Release note The PyPI sdists for `langchain-core`, `langchain-model-profiles`, `langchain-tests`, and `langchain-text-splitters` now include the MIT `LICENSE` file. --- 🤖 This description was written with assistance from an AI agent.

chore(infra): add missing LICENSE files to publishable packages Copy the repo-root MIT LICENSE into libs/core, libs/model-profiles, libs/standard-tests, and libs/text-splitters so hatchling includes it in each package's PyPI sdist, matching the pattern already used by libs/langchain, libs/langchain_v1, and all libs/partners/* packages. Verified by building each sdist with `uv build --sdist` and confirming the LICENSE is present in the tarball: - langchain_core-1.5.3.tar.gz - langchain_model_profiles-0.0.6.tar.gz - langchain_tests-1.1.9.tar.gz - langchain_text_splitters-1.1.2.tar.gz
