multi-party conflict detection
==============================

The current Magic-Folder remote conflict detection design does not properly detect remote conflicts
for groups of three or more parties. This design is specified in the "Fire Dragon" section of this document:
https://github.com/tahoe-lafs/tahoe-lafs/blob/2551.wip.2/docs/proposed/magic-folder/remote-to-local-sync.rst#fire-dragons-distinguishing-conflicts-from-overwrites

This Tahoe-LAFS trac ticket comment outlines a scenario with
three parties in which a remote conflict is falsely detected:
