This workshop turns the ideas from the Hypercerts on AT Protocol talk into something participants can shape and build. It's deliberately adaptable: the agenda will flex based on who shows up.

Depending on the room, we'll spend time on one or more of the following:
- Conceptual mechanism design: Working in small groups, participants sketch a funding or decision-making mechanism for a real situation they care about. What gets recorded? Who issues claims, who evaluates them, who allocates? Where does an open, shared data layer help, and where doesn't it?
- Technical building: For participants already building, we go into the protocol layer: hypercerts lexicons on AT Protocol, how to issue and read records, how to integrate with existing apps in the ecosystem, and what's missing in the current stack that needs to be built.
- Evaluation tools: For participants focused on impact assessment, we work on evaluator workflows: how evaluations are structured as records, how they accumulate over time, and how to design tools that help domain experts and communities surface meaningful signal.

We'll start with a short check-in to map who's in the room (builders, funders, evaluators, researchers, curious newcomers) and use that to set the agenda for the rest of the session. Most workshops will end up doing two of the three threads in parallel.

What participants leave with: a concrete sketch, technical starting point, or evaluation design for their own work; a working vocabulary for hypercerts and ATProto-based coordination; and direct contact with others working on adjacent problems.

Scheduling note: This workshop pairs with the 30-min talk Funding on the Open Social Web: Hypercerts on AT Protocol and is best scheduled after it. Attending the talk is helpful but not required — we'll do a fast recap at the start.
