Each panel is a hypermedia object: an interactive thing whose state is a projection over a thread of signed, content-addressed messages (the cbcl-rs G-Set CvRDT), rendered by an untrusted view the browser sandboxes. Interacting emits a new signed message — the view never holds a key. This page imports the real hypermedia/*.js modules; the text/html cards run in a true <iframe sandbox="allow-scripts"> with a host-imposed CSP (network-inert), and every accepted/rejected message appears in the wire tap on the right. Every object has its own URL: a mutable ni: name (resolves to current state) and an immutable pin (the thread as of a frontier). Try the copy link / pin buttons, edit the budget in either representation, grant the task, and fire the poll's forge probes.
