Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain physical chains by type and use, support selection, safety and maintenance, describe ceremonial and decorative chains, and separate abstract senses of chain.

A series of connected links or rings, usually of metal, used to lift, pull, secure, transmit power or adorn, from anchor and lifting chains and bicycle drive chains to watch chains, guild chains of office and jewellery chains; the word also denotes sequences and networks such as supply chains and chain stores, which are separate senses.

What it is for: Lifting, securing, transmitting power and adornment.

It can be identify chain types and grades; support safe selection and use; explain maintenance and inspection; separate abstract senses.
