Contributor guide
Research direction
The issue names the Python SDK transforms AsIter and AsSingleton and the WindowMappingFn concept, but provides no files or tests. Start by locating those transform entry points and existing tests for window mapping, then determine the expected behavior from the linked BEAM-2133 Jira issue. Done means the affected transforms accept WindowMappingFn with coverage for the intended behavior.
