 ### Electron source integration
 
+- Merge the active Electron source stack onto main through PR #76. Retain
+  Swift maintenance and rollback source, and keep Swift 0.2.41 stable. The

 - Start a fresh quota activity series when a connection changes. Retain prior
   observations outside the replacement account's heatmap, and preserve the
   current series on normal relaunch and Muse collection Stop/Start.

+- Beta.6 can retain the previous account's quota activity after disconnecting

+- Default branch: `main`. The Electron integration merged through PR #76 as
