What does a file system event tell you?
File system events tell you that something in a given directory changed. In some cases, this is sufficient—for example, if your application is a print or mail spooler, all it needs to know is that a file has been added to the directory.
When to drop event flags in file system?
The dropped event flags are provided purely for informational purposes. If the root directory that you are watching is deleted, moved, or renamed (or if any of its parent directories are moved or renamed), the directory may cease to exist. If you care about this, you should pass the flag kFSEventStreamCreateFlagWatchRoot when creating the stream.
When to use the kfseventstreameventflagmustscansubdirs flag?
If an event in a directory occurs at about the same time as one or more events in a subdirectory of that directory, the events may be coalesced into a single event. In this case, you will receive an event with the kFSEventStreamEventFlagMustScanSubDirs flag set.

Why is yarn failing to install FSEvents While NPM succeeds?
This is not yarn. It is AWS giving you a 404 from one of the install scripts running through fsevents. Looks like it goes through with npm because it was cached. If you try again with Yarn it may go through if this was a temporary server issue.
