Games + maintenance
One scan can host evolving objects, rotating messages, and local secrets while keeping maintainer-signed safety authority separate from public play.
Scan view · riverwalk beacon / AED hallway
Public-play layer
- Evolving objects change after enough voluntary contributions
- Rotating messages and ephemeral drops create timed neighborhood moments
- Collaborative discovery unlocks the next object without points, XP, or leaderboards
Safety boundary
- Maintainer-signed status stays separate from lore and clue state
- If signatures conflict, safety copy overrides the object copy
- Resolver stores unlock state, not a movement history
Signed streams behind this card
- Maintainer stream In service / out of service, last verified, repair notes
- Object stream Current object form, rotating message, and local unlock conditions
- Trust chain Which nearby object vouched, whether the clue is revoked, and what appears next
Example object chain
Temporary drop
- A QR appears near the riverwalk for 48 hours
- It resolves to a hidden object instead of a generic reward screen
- Stewards can revoke it if the physical site needs to change
Collaborative unlock
- If enough people scan the first object, a second object wakes up in Czech Village
- The resolver only stores whether the threshold was met
- No account or player dossier is required to participate
Trust gate
- A third object appears only after another local object vouches for it
- Revocable physical clues keep the chain grounded in real space
- The object can disappear cleanly without preserving scan histories
The strongest mechanic is not points; it is anonymous participation in shared urban memory while the maintainer still signs safety-critical truth.
