Change overwritten by a concurrent edit

A transaction overwrote a field another participant changed recently (default ten minutes, configurable in HostConfig). The authority applies changes in arrival order and the later one wins (last writer wins). The earlier change is kept in the conflict log (collab.conflicts) with both values and surfaced to both participants through diagnostics and editor.overwrite.

#Common causes

• Two people (or a person and an agent) edited the same field at the same time.

#Fixes

• Look at the conflict log entry and set the field again if your value should win.

• Undo the agent turn if the previous value should be restored.
