[daabr]

Where: https://github.com/tzrikka/revchat/blob/main/pkg/slack/workflows/thrippy.go

Afterwards, run https://github.com/temporalio/sdk-go/tree/master/contrib/tools/workflowcheck for verification. Also run it on Timpani's code.

There may be some other false-positives related to map iterations that are deterministic.
