An EmDash plugin (native, content:write only) with one admin page: a diigo username and an ISO week. It reads diigo-cache's public page (?in=<week>&by=created) as microformats, follows rel=next, and creates a draft in issues shaped like seed/issues.json. Transport is a DIIGO_CACHE service binding rather than ctx.http.fetch: EmDash's SSRF guard refuses localhost, and the binding names one worker. Logic lives in src/week.ts with the fetcher passed in; tests read fixtures in diigo-cache's markup. The checklist's goal 2 now names potluck; DiigoBridge waits. Generated-by: Claude Opus 5.5
