Research loop writes a live campaign dashboard page at every record boundary #2144

Important

Problem — The research loop's record step mentions "the campaign dashboard widget refresh where one exists", but no dashboard exists and nothing tells the director what to write or where.
Approach — Give the research skill a dashboard contract: at kickoff and at every record boundary the director rewrites one static HTML page beside the ledger (status line with last-updated time, a "needs you" line, the loop table with verdicts, key findings, plots as sibling image files), and posts its file link once in chat. The mode card's record sentence points at it.
Scope — in: research skill + both copies of the research mode card · out: develop mode.
