"Story tiddler template" refers to the template used to display a tiddler within the story river.

The core story tiddler template can be found in $:/core/ui/StoryTiddlerTemplate

The Story Tiddler Template Cascade is used to choose the template to be used for a particular tiddler. By default, the edit template is used for tiddlers in draft mode, and the view template used otherwise.
