 ## References
 
-See `refs_raw.bib` — needs cleanup before submission.
+See `refs_clean.bib` — 10 verified, deduplicated entries ready for submission.
 
-**Known issues with current references:**
-- Some entries are duplicated (at least the Attention and LLaMA papers)
-- Mix of DOIs, arXiv IDs, and bare entries — need consistent formatting
-- MMLU paper year might be wrong (listed as 2019, but I thought it was 2021?)
-- Several entries missing journal/venue information
-- Entry types inconsistent (@misc vs @article)

-## TODO
-- [ ] Clean bibliography
-- [ ] Verify all years and identifiers
-- [ ] Remove duplicates
-- [ ] Format consistently for submission
