Find Meta placements that are not earning their spend

Breaks spend and results down by placement (platform and position) and says which placements cost far more per result than the account average. Use when: the user suspects one surface is wasting money, or before deciding whether to leave Advantage+ placements on. Do not treat a recommendation as a decision. Restricting placements shrinks the auction Meta can buy in, so costs on the remaining placements usually rise — say that whenever you report an exclusion. Do not exclude a placement on a few days of data or on a placement with a small share of spend; the verdicts already stay neutral there. Returns the placement table, a verdict per row, and the exact publisher_platforms list to pass to meta_update_ad_set if the user agrees. It writes nothing itself. If everything is close to average, the right answer is to change nothing.
