Steer matter paths with live decisions
An interactive installation - explore a flooded observatory where glowing matter builds paths from your movement, gaze and actions, with real-time Jev decisions deciding how the world responds, shipped as a playable web app with live-decision tests.
01 · Role in the system
What Jev does here
The observatory reacts to how you move and where you look: each player action becomes typed questions over the game state, and Jev's calibrated answers steer how the matter grows paths and what the flooded world does next - decided in real time through the official @typesafe-ai/sdk, with the decision endpoint exposed as an API route the client polls. Tests cover the live-decision flow, and the piece is playable at livingmatter.vercel.app. It sits between game and installation: the judgment engine is not scripting outcomes but continuously re-deciding how an environment behaves around the player.
02 · Control boundary
Where Jev sits
Jev as the live reactive brain of an interactive installation: player movement, gaze and actions become typed questions each frame, calibrated answers steer matter growth and world behavior through a decision API route, covered by live-decision tests.
Code owns the loop, permissions, thresholds, validation, and side effects. Jev owns only the bounded judgments described above.
03 · Known limits
What this evidence does not prove
- Installation scope; the reactive behavior is artistic, not a game with win states.
- 2 stars; decision latency on the live path is not published.
- Requires the hosted Jev API; no offline mode.
