-    - **Engine:** Meta-Llama-3.1-8B-Instruct (Hugging Face Inference)
-    - **Data Sources:** Congress.gov API (Legislation), Federal/Committee RSS (Schedules & News)
-    - **Logic:** Tiered priority sorting (Legislation > Agency Action > Media)
+    * **AI Engine:** Summaries and keyword extraction are powered by **Meta-Llama-3.1-8B-Instruct**, restricted by strict anti-hallucination prompting.
+    * **Data Sources:** Live API integration with Congress.gov, official federal RSS feeds, and master committee schedules.
+    * **The "Bouncer" (Filtering):** Articles and bills are strictly filtered against a hardcoded tech-policy dictionary before the AI reads them.
+    * **Data Retention:** News expires from the UI after 30 days, Schedules after 60 days. Legislation is retained for the duration of the current Congress.
