The confidence decay engine
DynamoDB TTL isn't used to delete sightings — it's used as a live confidence score rendered directly in the UI.
Live Confidence Decay
Every sighting lives 30 minutes. Cards glow bright orange when fresh, fade to gray as they age — the database TTL is the UI.
Community Confirmation
Tap "Still there" to extend a sighting by 10 minutes. The more confirmations, the brighter the blip.
Scout Trust Tiers
Bronze to Gold — verified scouts get a confidence boost. Build your reputation by reporting accurately.
