Start with domain/workflow/internal/execute/event_handle.go, especially mustMarshalToString at line 835 and its callers in handleEvent, then trace the goroutine started from workflow_run.go:309. Reproduce or isolate the concurrent map iteration and write during workflow event handling; done means the panic no longer occurs under concurrent execution and the relevant behavior is covered by a regression test.
