Linked spend

Linked spend is project spend that opub can connect to a compute key and recent local session context. It tells donors that donated compute was used through a key associated with the project.

In opub, Linked is a narrow public signal. It helps donors trust that spend came from the project workflow they funded, while keeping prompts, responses, code, diffs, commits, and local files outside opub.

Linked spend does not prove what work happened inside the maintainer's tool. It means opub could connect the spend event to the compute key and project context.
