Alright, status report. The official documentation talks about the folders /chrome/browser/sync/engine, /chrome/browser/sync/syncable and /chrome/browser/sync/protocol. These folders are missing from the source tree, as you can see here: https://chromium.googlesource.com/chromium/src.git/+/master/chrome/browser/sync/ https://chromium.googlesource.com/chromium/src.git/+/master/... However, I decided to give the benefit of the doubt and did a few file-searches, in case the files were moved at some point and the documentation was just not updated. And it seems like that's actually the case. The folder /sync contains all three missing folders (engine, syncable, protocol) and more: https://chromium.googlesource.com/chromium/src.git/+/master/sync/ https://chromium.googlesource.com/chromium/src.git/+/master/...
