+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Build a location-based game framework combining zkGPS privacy proofs with collaborative mapping for treasure hunts, collectibles, and IoT-anchored discoveries.
+
+Use cases:
+- Conference treasure hunts with provable location without disclosure
+- Collectible elements anchored to physical locations
+- Crafting/combining discovered items
+- Mycelial network growth between discovered nodes
+- IoT hardware integration (NFC tags, BLE beacons)
+
+Game mechanics:
+- Proximity proofs ("I'm within 50m of X" without revealing where)
+- Hot/cold navigation using geohash precision degradation
+- First-finder rewards with timestamp proofs
+- Group discovery requiring N players in proximity
+- Spore collection and mycelium cultivation
+- Fruiting bodies when networks connect
+
+Integration points:
+- zkGPS commitments for hidden locations
+- Mycelium network for discovery propagation
+- Trust circles for team-based play
+- Possibility cones for "reachable discoveries" visualization
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria

+- [ ] #1 Discovery anchor types (physical, virtual, IoT)
+- [ ] #2 Proximity proof verification for discoveries
+- [ ] #3 Collectible item system with crafting
+- [ ] #4 Mycelium growth between discovered locations
+- [ ] #5 Team/group discovery mechanics
+- [ ] #6 Hot/cold navigation hints
+- [ ] #7 First-finder and timestamp proofs
+- [ ] #8 IoT anchor protocol (NFC/BLE/QR)
