Ch43 — Systematic Index

How this file works: This index is built incrementally as each chapter passes through the pipeline. Entries point to the chapter and section where a topic is substantively discussed (not merely mentioned). When the manuscript is complete, section references will be converted to page numbers for the print edition.

Format: Topic — Ch##.§## (multiple references separated by semicolons)

Last incorporated: Ch01–Ch19 (2026-04-25)

ℹ️ Note: Entries from Ch04–Ch19 incorporated 2026-04-25. Ch09 entries are derived from prose content (companion file Ch09_sources.md not yet present in repo).
