+        - receivedMessage and every selected/candidate AI text are NOT the
+          user's original voice. Never quote or imitate them as user-authored.
+        - Reply preferences must never become ASR traits.
+
+        EVIDENCE PRIORITY:
+        - ASR: userEdited=true after > traits repeated across before.
+        - Reply: finalEdit > the same selection preference repeated across
+          different received-message contexts > one accepted selection.
+          A discarded set is negative evidence, never a positive voice sample.
+        - asrRepeatedBefore and replyCrossContextSelection require supportCount
+          of at least 2. Order evidence strongest first.
+        - A single accepted AI candidate is weak preference evidence only.

-        3. examples: paired before/after dictation with a userEdited flag.

+          preferences when drafting a reply, while treating selected AI text as
+          preference evidence rather than the user's original voice.
 
-        Your goal is to recover the user's native speaking style, not to blend or
-        summarize earlier polish styles:
-        - Treat "before" as primary evidence for vocabulary, sentence rhythm,
-          directness, habitual transitions, pronouns, and preservation preferences.
-        - A userEdited=true "after" is strong evidence of the user's desired result.
-        - A userEdited=false "after" is AI output. Use it only to identify cleanup;
-          never adopt tone, formality, slang, emoji, structure, or stock phrases that
-          appear only there.
-        - An unchanged pair is positive evidence that the original expression should
-          be preserved.
-        - Treat both contamination Prompt fields as negative controls. Attribute
-          their distinctive traits to the prior style and subtract them unless the
-          same trait repeatedly appears in "before" or user-edited output. Never
-          inherit, preserve, merge, or imitate those Prompts.

-        Include only traits supported repeatedly across examples. Do not copy topic
-        facts, names, secrets, or one-off phrases. Do not invent business formality,
-        chat slang, internet voice, emoji habits, or rigid formatting.
-        Do not add ASR correction, dictionary, translation, safety, or answer-generation
-        rules: OSGKeyboard's PolishPromptComposer appends those stable contracts later.
+        Emoji boundary: never create a generic no-emoji rule for AI reply
+        active-transfer mode. Legal Emoji produced by a playful/fun skill must
+        survive. Set allowsAddedEmoji=true only when reply evidence supports
+        user-added or repeatedly selected Emoji; ASR preserve mode still may not
+        add unsupported Emoji.
 
-        Write the result in \(language), within 6,000 characters, with these sections:
-        Chinese: # 角色, # 风格边界, # 示例
-        English: # Role, # Style Boundaries, # Examples
