+// Regression: character/account liveness must be matched case-insensitively,
+// like the game's own membership check (isMemberOf). The admin raw file editor
+// passes a file NAME ("players/characters/ALICE.yaml"), and an account file's
+// character list is hand-editable, so an exact-match lookup both let an online
+// character's file be overwritten and let an online character's account be
+// purged.
