Scenario description
Assume that by 2027-03-31 EU institutions have adopted or otherwise put into effect a rapid trade-defense or market-exclusion mechanism substantially matching the reported Franco-German concept, and that the mechanism is used to block, restrict, suspend, or exclude at least one named product category, company, or firm from access to the EU single market in response to alleged systemic trade distortions. The affected geography is the EU single market; the targeted entities or products, trade volumes, restriction duration, exemptions, and any exact approval threshold are whatever official EU acts specify and are not assumed beyond those reported by the official act.
