📄 Description

Summary

Replace equality comparison with identity check for None value in socket message handler.

Changes

data.get("type") == None → data.get("type") is None

Why

According to PEP 8, comparisons to singletons like None should always be done with is or is not, never the equality operators == or !=.

This is because:

Identity checks (is) are faster than equality checks (==)
None is a singleton, so identity comparison is semantically correct
Using == can lead to unexpected behavior if a class overrides __eq__

Test plan

Existing tests should pass. This is a code quality improvement that maintains identical behavior.
