- Safe Marketplace Migration Cost Thresholds: Separate structural Block, payback Review, implementation Review, headroom Review, narrow Ready, monitoring, stop, and restoration.
- Add an Owned Store vs Move Marketplaces: Hold product, currency, contribution, forecast, privacy, and evidence boundaries comparable while exposing different migration work.
