+# KAT World Model — RSSM v2 (Tutoring Domain)
+
+A **Recurrent State-Space Model (RSSM)** trained for tutoring state prediction, part of the **KAT (Knight Academic Tutor)** system by [QRI (Qualia Research Institute)](https://qri.bio).
+
+## Model Description
+
+This is a complete world model for predicting tutoring session dynamics — student state transitions, reward signals, and session termination. It uses a DreamerV3-inspired RSSM architecture with VL-JEPA-style EMA target encoding.
+
+### Architecture
+
+```
+TutoringRSSM (2,802,838 params)
+├── ObservationEncoder: obs_dim(20) → encoder_hidden(256) → latent_dim(128)
+├── ActionEmbedding: action_dim(8) → embed_dim(32)
+├── DeterministicTransition: GRU(hidden_dim=512)
+├── StochasticLatent: Diagonal Gaussian prior/posterior (latent_dim=128)
+├── ObservationDecoder: feature_dim(640) → decoder_hidden(256) → obs_dim(20)
+├── RewardPredictor: feature_dim(640) → 1
+├── DonePredictor: feature_dim(640) → 1
+└── EMATargetEncoder: momentum=0.996 (VL-JEPA heritage)
+```
+
+**Feature dimension**: `hidden_dim + latent_dim = 512 + 128 = 640`
+
+### Observation Space (20-dim)
+
+The 20-dimensional observation vector encodes tutoring session state:
+
+| Dims | Signal |
+|------|--------|
+| 0-3 | Mastery estimates (per-topic confidence) |
+| 4-7 | Engagement signals (attention, participation) |
+| 8-11 | Response quality (accuracy, depth, speed) |
+| 12-15 | Emotional state (frustration, confidence, curiosity) |
+| 16-19 | Session context (time, hint level, attempt count) |
+
+### Action Space (8 discrete actions)
+
+| Index | Strategy |
+|-------|----------|
+| 0 | SOCRATIC — Guided questioning |
+| 1 | SCAFFOLDED — Structured support |
+| 2 | DIRECT — Direct instruction |
+| 3 | EXPLORATORY — Open exploration |
+| 4 | REMEDIAL — Error correction |
+| 5 | ASSESSMENT — Knowledge check |
+| 6 | MOTIVATIONAL — Encouragement |
+| 7 | METACOGNITIVE — Reflection |

+model.load_state_dict(ckpt["model_state_dict"])
+model.eval()
+
+# Initialize state
+h, z = model.initial_state(batch_size=1)
+
+# Observe a tutoring step
+obs = torch.randn(1, 20).cuda()  # Student observation
+action = torch.tensor([0]).cuda()  # SOCRATIC strategy
+result = model.observe_step(h, z, action, obs)
+
+h_new, z_new = result["h"], result["z"]
+pred_obs = result["pred_obs"]       # Predicted next observation
+pred_reward = result["pred_reward"]  # Predicted reward
+pred_done = result["pred_done"]      # Predicted session end
+
+# Imagination (planning without observation)
+imagined = model.imagine_step(h_new, z_new, torch.tensor([3]).cuda())
+# Returns predicted state without requiring real observation
+```
