The Architecture Committee (ArchCom) has adopted a new charter and renamed itself the Wikimedia Technical Committee (TechCom). The new charter defines the committee's scope, purpose, operation.
TechCom is the guardian of the integrity, consistency, stability, and performance of the software supporting the Wikimedia projects. It acts as the senior advisor and the convergence point of all decisions related to technical work that is strategic, cross-cutting, and/or hard to undo. — Mission statement
The commitee's authority over technical development at the WMF is also specified – it acts as an extension of the Chief Technical Officer.

You can fix a page by opening it for editing and then saving without changing anything. (Phabricator task T170039)
