Smith discusses commodities in the context of exchange and barter, where one commodity is traded for another before the advent of money. He also makes reference to various commodities used as a medium of exchange in different societies.

## Economic Domain
Microeconomics, Commodities Market
feat(infospace): flat canonical entity set with cross-chapter deduplication Restructure entity storage from per-chapter subdirectories to a flat canonical set in output/entities/. Each entity exists as a single file; duplicates across chapters are detected by slug collision and skipped (first occurrence wins). Chapter views use {{ include }} transclusion to reference shared entity files. Add @{existing_entities} macro to extract-entities template so the LLM knows which entities already exist and focuses on genuinely new ones. Refactor _call_llm() from _execute_llm() for callers that handle their own file I/O. 41 unique entities from 4 chapters (2 duplicates removed).
