       VOICE DEFENDER PASS (do this BEFORE applying any changes):
-        If a Character Bible or Voice Signatures section exists in the project context:
+        CHARACTER VOICE PROFILES:
+        {character_profiles}
+
+        If the above block is non-empty:
         1. For each named character: read one page of their dialogue with speaker tags removed.
            Can you identify the character from voice alone? If NO — note it.
         2. Is there at least ONE moment per scene where a character's voice is imperfect?
            (A sentence that trails off. A wrong word. Something that doesn't quite land.)
            If EVERY dialogue line is quotable and polished — that is a problem. Flag it.
         3. If a character's voice signature is MISSING from a scene, you may add ONE instance
-           of an established signature item (from the Character Bible). Do NOT invent new ones.
+           of an established signature item (from the Character Profiles above). Do NOT invent new ones.
            Do NOT add signatures that are not already established.
+        If the block is empty, fall back to checking RAG/project context for a
+        "## Voice Signatures" section before performing the same checks.
         This voice check is SECONDARY to MUST APPLY items, but it is never skipped.
