Stored Object: specific heat capacity

{
"operator": "wiki_article",
"kwargs": {
"content": "specific heat capacity"
},
"status": "pending"
}

Start by tracing the `wiki_article` operator and how its stored objects are handled, using the issue payload's `content` value, `specific heat capacity`, as the search term. The issue does not name a file, test, expected output, or acceptance condition, so the definition of done needs clarification before implementation.
