Advertisement in LLMs (1)

First note in the LLM Advertising series.

Placeholder. The questions this note will take up:

• What counts as an advertisement when the surface is a chat, a tool call, or a retrieved snippet?
• How should serving policy differ from web display ads?
• How do you tell user intent from induced intent?
• What is worth measuring besides click-through?

More notes will sit next to this one. The project landing stays at LLM Advertising.
