Wikipedia Transparency

Wikipedia Transparency displays reliability signals directly on Wikipedia article pages. The extension only runs on real article pages (main namespace), not on special/project/user/talk pages.

What The Extension Does
Adds a discreet banner at the top of the page with:
trust score (0-100)
risk level (low/moderate/high)
total page revisions (without loading full history)
score base (number of revisions actually used for the score)
a quick metrics summary
a "why" explanation when the score drops
3 latest contributors with links to their profile and their diff
detected Wikipedia quality label (Featured article / Good article / none)
top 5 contributors (added words) with links to their contribution pages
Explicitly handles sensitive cases:
strong score decrease when there is high activity/conflict over 3 months
strong score decrease for very recent pages with little history
How The Score Is Calculated
The trust score is a 0-100 score.

Starting base: 80
Bonuses:
+8 if at least 40 unique contributors
+4 if at least 100 unique contributors
+8 if the article is highly distributed (>=200 revisions, >=80 contributors, and top contributor share < 12%)
Penalties:
-14 if the top contributor exceeds 22% of revisions
additional -8 if they exceed 35%
-8 if more than 30% of edits are anonymous
-14 if reverts exceed 18%
additional -8 if reverts exceed 30%
-8 if controversy comments exceed 10%
-10 if more than 55% of edits happened in the last 30 days
Recent-page cases:
strong penalty if the page is recent and has little history (e.g., fewer than 20 revisions within 30 days)
"Edit war" case (3-month window):
penalty for high recent activity
penalty for sudden acceleration vs the previous 3 months
penalty for many recent reverts
The final score is clamped between 0 and 100, then mapped to levels:

Low risk if score >= 70
Moderate risk if score < 70
High risk if score < 50
