The Story Sweep — what the new medium can newly do
Where the Standing Frontier Sweep watches eight commercial-and-scientific veins and the HKG sweep watches longevity, the Story Sweep watches one question on a rhythm: what can the storytelling medium newly do? New XR surface, new interactive-narrative result, new participatory-economy mechanic, new agentic-character tool — each is a candidate, and each becomes a card only once a primary source and a date are attached.
The output is capability, not lore. Every verified card ends with a "so we should" aimed at a story-maker: this is now possible, so The Call (or a work like it) could use it to pull one more person across the threshold. The garden's job is to keep the medium's frontier mapped and fresh so the myth-building never runs on last year's assumptions about what a headset, a phone, a voice, or an agent can hold.
The line we never cross. The sweep verifies the medium; it never "verifies" the story. The Call and its world are owned canon — imaginative, deliberate, and labeled as canon. Keeping the two apart is exactly what lets this garden be the most creative shelf in the cabinet and still carry a receipt on every factual claim.

Internal-first. Two content classes kept strictly apart: verified medium-frontier signals (normal RDKG discipline — primary + date + falsifier) and owned canon (labeled canon, never verified-tier). Trade press and festival buzz are leads, never source_url. Credit the artists, studios, and researchers. Nothing here diverts engineering from the BKG paying-customer P0; any tool is a stub/spec. Deploy is Netlify-only.
