The city card had accumulated independent checks for AI status, market availability, stale observations, breakouts, peak timing, model consensus, and next-bulletin waits. This introduces a CityDecisionState builder so UI components consume one coherent recommendation, urgency, evidence quality, AI status, market status, badges, and primary reason.
Constraint: Keep the current card copy and badge priority behavior while moving decision-state ownership out of the component.
Rejected: Refactor calendar and opportunity lanes in the same commit | the shared model should land behind the city card first, then other views can migrate with smaller visual-risk diffs.
Confidence: high
Scope-risk: moderate
Reversibility: clean
Tested: npm run build
Not-tested: Browser visual regression and dedicated unit tests for every decision-state combination.
