Yup. In my framework, attestations are contextual. Some contexts are broad, others are specific / niche. Trust (or lack thereof) in a broad context automatically implies trust (or lack thereof) in all sub-contexts.
The most broad of all would take the form: “Alice trusts (or doesn’t trust) Bob for all actions, in all categories.” In other words, in all contexts. Trust attestations are averaged by your Grapevine to create context-specific influence scores, and the “base layer” of influence scores is the layer that applies to ALL contexts.
