Finds fresh buy and replacement ideas across the runtime universe. Uses the latest regularized joint-policy ranker scores from shared prep, combining price action, sentiment, forecast, technical, and fundamental signals. Returns global recommendations plus strategy-profile context, with action, model confidence, risk notes, and per-signal joint-policy contributions explaining why each ticker surfaced. Useful when looking for new positions, portfolio rotation candidates, or replacements for weaker holdings. Freshness is market-calendar aware and stale or incomplete prep is surfaced explicitly instead of silently falling back. Use market_scope='us' for US-only requests and market_scope='kr' for Korean-stock requests; omit market_scope only when the user wants the agent/account's full configured market scope.
