 2026-06-22 | "For my publication list https://enquistlab.github.io/publications/ I would like you to do a deeper dive on papers that can overlap with Ecological Stoichiometry - I have several papers on nutrient traits. Also my chapter with Michaletz and Kerkhoff is a stoiciometry paper as well as my 2017 elevational gradient paper" — Added deeper stoichiometry overlap overrides: strengthened Michaletz/Kerkhoff chapter hints, added nutrient-stocks ecosystem allometry paper, added requested 2017 tropical elevation-gradient productivity paper overlap, and added ecological-stoichiometry to 2019 leaf nutrient traits paper.
 2026-06-22 | "Run mandatory final pre-return gate for stoichiometry overlap deep-dive update in /Users/brianjenquist/VSCode/enquistlab-site-migration. Verify prompt log, Rmd/package triggers, and git push status for current changed files." — Gate request logged verbatim for exact-match policy check.

Verify prompt log, Rmd/package triggers, and git push status." — Gate request logged verbatim for exact-match policy check.
+2026-06-22 | "Good but you missed several papers. Our PFTC data papers have lots of stoichiometry. Also Enquist et al. 2017 testing trait theory across elevation is stoichiometric. Please do a deeper dive on my publications" — Added 6 new stoichiometry overrides: 2025 Halbritter nitrogen-grazing, 2024 Halbritter Puna, 2025 Halbritter Afromontane, 2025 Vandvik Norway, 2023 Vandvik Svalbard, 2017 Enquist trait-scaling elevation. Committed and pushed to main.
