How a host page wires it in
Two file includes + one register call per goal. That's it.
Drop-in pattern for any FFH page
// 1. Include the layer (head of page) <link rel="stylesheet" href="recalculate-ui.css"> <script src="recalculate-engine.js"></script> // 2. Register the page's goals (any number) and start watching FFH.Recalculate.register({ goalId: 'walk-30x5', label: 'Walk 30 min, 5 days/week', tracker: 'sports-health', thresholdDays: 7, barrierProfile:'movement' // → loads movement diagnostic + resources }); FFH.Recalculate.watch(); // drift checks run every 60s // 3. When the user logs progress anywhere, just tell the layer: FFH.Recalculate.logAction('walk-30x5');

📡 PHIT pipe: The
phit.pattern.signal event carries only anonymized barrier tags + tracker name + zip (if available). Individual identity never leaves the device. Aggregate signals feed the community pattern library — exactly the civic-planning intelligence PHIT was built to surface.
