# Optional extras use compatible ranges (like the core SDK above) so downstream
# consumers can coexist with other packages and pick up security patches without
# forking. Reproducibility for our Docker/CI comes from `uv.lock` (images install
# via `uv sync --frozen`). A few deps stay exact-pinned: litellm's own
# sub-packages and the opentelemetry trio move in lockstep, and grpcio is
# supply-chain-pinned to a vetted, aged release.
