# `Runic.Workflow.Events.FanOutFactEmitted`
[🔗](https://github.com/zblanco/runic/blob/main/lib/workflow/events/fan_out_fact_emitted.ex#L1)

Event emitted when a FanOut node splits an enumerable input into individual facts.

One event is produced per item in the enumerable. During `apply_event/2`, the emitted
fact is logged, a `:fan_out` edge is drawn, and the `mapped` tracking state is updated
for downstream FanIn coordination.

# `t`

```elixir
@type t() :: %Runic.Workflow.Events.FanOutFactEmitted{
  emitted_ancestry: {term(), term()} | nil,
  emitted_fact_hash: term(),
  emitted_value: term(),
  fan_out_hash: term(),
  source_fact_hash: term(),
  weight: non_neg_integer()
}
```
