 Assemble the digest following `prompts.digest_intro`.
 
 **ABSOLUTE RULES:**
+- NEVER repeat an item. Each tweet, blog post, and podcast episode appears exactly once.
+  No restating the same summary under a second heading.
 - NEVER invent or fabricate content. Only use what's in the JSON.
 - Every piece of content MUST have its URL. No URL = do not include.
 - Do NOT guess job titles. Use the `bio` field or just the person's name.

 - Skip any source with nothing new
 - Under each source, paste the individual summary you generated

+- NEVER repeat the same summary, paragraph, or "Key insights" list two or three times.

 ## Instructions
 
+- Produce EXACTLY ONE remix for this episode. One episode = one summary block. Never
+  write the summary more than once, and never split a single conversation into multiple
+  entries — even a long, multi-topic live interview is one episode.
 - Write a remix of 200-400 words
 - Start with a one-sentence "The Takeaway" — what's the single most important takeaway?
 - Introduce the context and the speaker's information (name, role/company, background) and why the audience should care
