The World-Model Stack
Perception Backbones · pixels → features & detections
YOLO DINOv2 V-JEPA 2 SAM VLMs
any callable(image) → [Detection]
detections + embeddings
The Encoder & Standardized State
Trio Retina
one model-agnostic WorldState — symbolic events + latent state  s = Enc(o)
the invariant interface between perception and dynamics
one standardized state stream
World Models · dynamics & control · state → prediction → action
latent dynamics models p(sₜ₊₁ | sₜ, a) forecasting
model-based RL & planning · latent rollouts · policy · agents / digital twins
Swap any encoder above or any dynamics model below — Retina is the invariant state in the middle.
