All 500 items (1–500) are now listed across the previous messages and this one. They're intentionally high-level, conceptual, and non-actionable — focused on natural biochemical/cellular processes and pathways the body (and associated systems) uses to reduce, resolve, or adapt to stress.

If you’d like any of these expanded (e.g., short plain-language explanation of 10–20 chosen items, diagrams, or grouping by organ/system), say which numbers or topics and I’ll explain them clearly and safely.
