Add OpenAIAdapter for the OpenAI chat completions API (apikey-chatgpt.txt or OPENAI_API_KEY). Set default model to arcee-ai/trinity-large-preview:free for the infospace pipeline and increase max_tokens from 4096 to 8192. Reprocess chapter 05 with Trinity Large (was Gemini: 1 truncated entity, now 19 complete entities). Process chapters 06 (Aurora Alpha, 10 entities) and 07 (Trinity Large, 15 entities including regenerated violent-policy.md). Canonical set now at 85 unique entities. Add entity archive policy: entities are never silently deleted. Retired entities move to output/entities/archive/ with a dated reason header. New CLI option: --archive-entity <slug> --reason "...". The --list output shows the archive count alongside the canonical set. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

natural-price
Definition
The natural price of a commodity is the price that exactly covers the costs of production, including rent of land, wages of labour, and profits of stock, at their natural rates. It represents the central or equilibrium price toward which market prices continually gravitate, reflecting what the commodity "really costs" to bring to market. This price provides the ordinary rate of profit to the seller and is the lowest price at which they are likely to sell for any considerable time under conditions of perfect liberty.
Source Chapter
Book 1, Chapter 7: "OF THE NATURAL AND MARKET PRICE OF COMMODITIES."
Context
Smith introduces the concept of natural price as part of his analysis of price determination. He distinguishes it from market price and explains how it serves as the gravitational center toward which all commodity prices tend. The natural price is presented as the price that would prevail when the commodity is neither in excess nor shortage relative to effectual demand.

General Theory
Smith's Original Wording
"When the price of any commodity is neither more nor less than what is sufficient to pay the rent of the land, the wages of the labour, and the profits of the stock employed in raising, preparing, and bringing it to market, according to their natural rates, the commodity is then sold for what may be called its natural price."
Modern Interpretation
The natural price functions as Smith's equilibrium concept - the price that would prevail in a competitive market when supply equals demand. It represents the long-run cost of production plus normal profit, serving as a benchmark against which actual market prices fluctuate. This concept anticipates later economic theories of supply and demand equilibrium and long-run cost structures.
