    # diff; tests/test_gateway_request_path.py pins the agreement itself.

# langgraph-sdk 0.4.2 (pulled in by langgraph 1.2.9 for DeltaChannel) pins
# `websockets<16,>=14`, silently downgrading websockets 16.0 -> 15.0.1. The
# pin is not grounded in any API incompatibility: websockets 16's only
# breaking change is requiring Python >=3.10 (we require >=3.12), the sdk
# only imports `websockets.asyncio.client`/`websockets.exceptions` (both
# 16-compatible), and DeerFlow never uses the sdk's WebSocket transport
# (httpx/SSE only). DeerFlow does have one direct consumer of its own: the Buzz
# channel (`app/channels/buzz.py`) imports the top-level `websockets` package and
# calls `websockets.connect()`, which in 16.0 is the same asyncio client the sdk
# uses, re-exported at the package root -- so it is covered by the same
# compatibility argument. Pin the exact pre-upgrade 16.0 for that plus the IM
# channel integrations (dingtalk-stream, python-telegram-bot, etc.) that ran on
# it before. Remove once langgraph-sdk relaxes the pin upstream. Note: enabling
# the `openai[realtime]` or `slack-sdk[optional]` extras would conflict (they
# also cap websockets<16).
