The loom
How sources become cards, cards become a thread, and a thread becomes a brief.
The loom is the product metaphor. In the interface it is a section, three still lifes, and a doctrine. In a live product it would be the workspace. This template does not ship that workspace.
Cards
A card has a claim, a provenance, and a confidence you would speak. Anonymous paste is not a card.
Threads
A thread is the smallest story that would change the last sentence of a brief. If a source cannot touch that sentence, it belongs in the grove.
Briefs
A brief holds what is known, what is contested, and a recommendation. The seal stays blank until a named seat presses it.
If you add an editor later, keep the three-part shape. A long document with a sparkle button is a different product.
