 - Default IMA target for daily single-article summaries is the `daily` knowledge base.
 - Resolve that default target from reader `.env` (`IMA_DAILY_KNOWLEDGE_BASE_ID`, `IMA_DAILY_KNOWLEDGE_BASE_NAME`) and verify it at runtime before upload.
 - If the configured daily knowledge base is missing, try to locate it by name; if still missing, create `daily` and continue.

+IMA Markdown layout guidance for selected article deposition:
+
+- Prefer direct Markdown file upload into the knowledge base (`media_type=7`).
+- Remove stiff metadata headers such as `Source:` / `Category:` when preparing the IMA-facing Markdown.
+- Keep source traceability by placing `原文链接：` near the top, followed by the original URL on the next line.
+- Break long prose under `核心结论` and `主要论点` into short paragraphs for IMA readability instead of relying on platform auto-formatting.

 ## Operational Guidance
 
 - Prefer real run outputs over examples.
