+Subject: [PATCH] migrations: Map non-existant external users to Ghost
+
+When performing migrations, and need to remap external users to local
+ones, when no local mapping is possible, map the external user to Ghost,
+rather than the user who initiated the migration.
+
+Mapping the external user to the migration initiator has the potential
+of breaking assumptions elsewhere, like only having one review per pull
+request per user. Mapping these migrated, locally unavailable users to
+Ghost makes sure these - often hidden - assumptions do not break.
+
+Fixes #3860.

++- Fixed an issue where migrated activities (such as reviews) were mapped to the user who initiated the migration rather than the Ghost user, if the external user could not be mapped to a local one. This mapping mismatch led to internal server errors in some cases (forgejo/forgejo#3860).
