+## Freeform Traitor and Face Dancer facts — 29 October 2026
+
+**Prototyped / Partial.** New current-fact questions recognize an exact
+unique public leader name in a held-Traitor or unrevealed-Face-Dancer question,
+including supported single-operator combinations with other current facts.
+The editor previews the checked interpretation. The server uses the existing
+distinct predicates, and only the target sees the verified answer before
+replying; an unresolved Traitor choice yields I don't know. Absent or ambiguous
+names stay player-managed. The shared Cheap Hero / Heroine identity is
+supported; Duke Vidal is not an eligible named identity for this grammar.
+
+New interpretations carry version 9; earlier versions and unstamped questions
+retain their existing meaning. The wording is a provisional online
+interpretation, not general language understanding. Runtime evidence exercises
+dealt Traitors and Face Dancers and stages one unresolved Traitor choice;
+fixtures also stage conserved Truthtrance custody. Twenty-three related
+freeform files pass 103 cases. Broader questions, full rules and deployed
+verification remain open.
