Originally a narrow bump of mypy to `1.20` in four packages. Expanded to get the whole monorepo onto a single, current mypy and a consistent type-check configuration, so contributors no longer hit different mypy versions and divergent behavior depending on which package they touch. ### What changed - **Unified the mypy pin to `>=2.1.0,<2.2.0`** in every mypy-using package (6 libs + 14 partners), replacing the previously scattered pins (`1.10`/`1.17`/`1.18`/`1.19`/`1.20`, with assorted upper bounds). - **Unified the `[tool.mypy]` base per tier:** - libs: `plugins = ["pydantic.mypy"]`, `strict = true`, `enable_error_code = "deprecated"`, `warn_unreachable = true` - partners: `disallow_untyped_defs = true` - Normalized style (`disallow_untyped_defs = "True"` string → bool, quote/key consistency). - **Fixed the 20 real errors** mypy 2.1 surfaces: `redundant-cast` from improved narrowing (`core`, `langchain-classic`), a `var-annotated` for `_LOGGED`, a return-type widening in `langchain-groq`'s `_convert_from_v1_to_groq` (it can legitimately return a bare `str`), and stale `type-arg`/`unused-ignore` in `langchain-model-profiles` tests. ### Deliberate non-uniformity (documented inline in the relevant `pyproject.toml`s) Going fully byte-identical would surface ~196 additional errors that are *not* real bugs, so two settings are kept package-appropriate: - **`warn_unreachable`** is enabled on every strict lib **except `core`**, where it false-flags intentional defensive code — including the SSRF / IP-policy guards in `_security/` — as unreachable. - **`pydantic.mypy` plugin** is used only on `anthropic` and `perplexity` (their code is authored against it and reports ~99/~132 errors without it). It is *not* added to the other partners, where it only flags the public alias constructor API (e.g. `ChatGroq(model=...)`) in tests rather than finding bugs. - **`ollama`** is left on its `ty` type checker; it does not use mypy. --------- Co-authored-by: Mason Daugherty <github@mdrxy.com>
