The `httpx` package is unmaintained and Airflow is moving to the `httpx2` fork. The anthropic SDK made that jump in 1.0.0, so the provider's tests were building SDK errors from a package the client no longer uses; raising the floor keeps the two in step and lifts the `<1.0.0` cap added while 1.x was unvalidated. The ast-grep rule stops the migrated providers from regressing. It exempts `airbyte`, `common/ai`, `weaviate` and `microsoft/azure`, whose third-party SDKs are still built on `httpx` -- their objects cross that boundary, and the two packages' classes are distinct, so switching them would break at runtime rather than fail loudly.
