Games + maintenance
- Players find AED, filter, and trail-marker nodes
- Maintainer-signed status stays separate from game points
- Fix verified → local map unlocks the next route
Design space · stacked claims
Combining ideas
The strong patterns stack: one QR can stay a simple scan while the card behind it pulls from several signed, revocable streams.
Research demos, not shipping behavior yet.
Demo scan pages
Each page shows a scan view where one card aggregates multiple live claims while keeping authority boundaries clear.
- Games + maintenance Evolving objects stay separate from maintainer-signed safety
- Crisis cards + freshness Aid routing and food-batch safety update without scan tracking
- Markets + menus + surplus Co-op pass, menu state, and safe-to-take tags from clear signers
- Cedar Rapids city game In development — demo scan views for trust chains and relay play without tracking
Core combo patterns
Crisis cards + freshness
- Wallet aid card lists nearby pantry and fridge options
- Each food batch keeps made, expires, allergen, recall state
- Resource page updates without tracking who scanned
Markets + menus + surplus
- Co-op pass links to today’s stalls and live menus
- Prepared-food tags mark safe-to-take surplus
- Vendor updates one state object instead of reprinting
Best combos keep authority clear: the game can reward discovery, but only the maintainer signs safety; the crisis card can show food, but the kitchen signs freshness.
