This task involves the work of introducing a new //hidden// [change tag](https://www.mediawiki.org/wiki/Manual:Tags) that will be appended to edits that meet the conditions defined in T324730.
This hidden tag will enable us (volunteers and members of the Editing Team) to see evaluate the extent to which the reference check heuristic is getting initiated in expected cases.
→ //Where "expected" in this context means an acceptable level of false positives and negatives.//
Knowing the above will enable us to decide what – if any – adjustments (T327959) ought to be made to the said heuristic (T324730).
=== Requirements
# A //hidden// change tag is appended/associated with //all// edits, regardless of the editing interface used to make said edits that meet //all// of the following conditions (copied from T324730):
## A minimum of one new paragraph of text is added to the article they are editing
--- //Where "new" in this context means the content they are adding does NOT already exist elsewhere within the article.//
## The "new paragraph(s) of text" they are added does NOT include a reference
## The changes described in "1." and "2." are happening on a page within the **main namespace**
# This hidden change tag should be called: `editcheck-references`
=== Done
- [ ] All "Requirements" are met
