Visual check: not checked
The supplied captions do not identify Congress's April 6 opening of American ports or its break with the Navigation system. The event remains essential context for independence as an institutional process; its visual treatment has not been checked.
Why it matters
Commercial policy made separation practical and institutional before Congress named it as a constitutional fact.
Why this tier
Opening the ports replaced imperial trade law with continental authority and invited external relationships.
Counterfactual test: Continued adherence to Britain’s commercial system would have made political independence harder to enact and foreign support harder to secure.
