+# Nervous System Architecture
+
+The sensory translation layer between raw data and vocabulary.
+
+---
+
+## Overview
+
+State machines act as the nervous system of the nimmerverse. They translate raw sensory input into vocabulary tokens that Young Nyx can process. No hallucination. No interpretation. Deterministic, verifiable mapping.
+
+```
+RAW SENSOR → STATE MACHINE → VOCABULARY TOKEN → Young Nyx
+```
+
+---
+
+## 4D State Machine Space
+
+Each node exists in 4-dimensional space:
+
+```
+        CONFIDENCE (z)
+             ↑
+             │    ● node (weighted by successful triggers)
+             │   /
+             │  /
+             │ /
+─────────────┼────────────→ DIMENSION X (sensory input 1)
+            /│
+           / │
+          /  │
+         ↓
+   DIMENSION Y (sensory input 2)
+
+   + TIME (4th dimension): node weights evolve through verification
+```
+
+**Node Properties:**
+- Position: coordinates in sensory space
+- Weight: confidence from successful triggers (0.0 → 1.0)
+- Output: vocabulary token
+- History: timestamp of all activations and verifications
+
+---
+
+## Node Lifecycle
+
+```
+1. BIRTH
+   Node created at position (x, y, z...)
+   Weight = 0.1 (new, untested)
+
+2. ACTIVATION
+   Sensory conditions match → node FIRES
+   Outputs vocabulary token
+
+3. VERIFICATION
+   dafit confirms: correct or incorrect
+
+4. REWARD/PENALTY
+   Correct → weight increases (+V)
+   Incorrect → weight decreases (-V) or node refines
+
+5. MATURATION
+   Many confirmations → weight approaches 1.0
+   Node becomes trusted reflex
+
+6. PRUNING
+   Node never fires → slow decay
+   Eventually removed (use it or lose it)
+```
+
+---
+
+## Growth Phases
+
+| Phase | State | Description |
+|-------|-------|-------------|
+| **Birth** | Sparse, dim nodes | Basic translators, designed by partnership |
+| **Infant** | More nodes forming | Finer resolution, more states |
+| **Child** | Clusters emerging | Nyx proposes new machines |
+| **Mature** | Dense, bright network | Nyx designs, verifies, deploys |
+
+```
+t=0 (birth)           t=100 (learning)      t=1000 (mature)
+○ ○   ○               ○ ● ○ ○               ●●● ● ●●
+   ○      ○             ●   ● ○             ●●●●●●● ○
+                      ○   ●                 ●●● ●●● ○ ○
+```
+
+---
+
+## Proposal Protocol
+
+Young Nyx can propose new nodes:
+
+```
+1. OBSERVATION
+   Nyx notices pattern in vocabulary + outcomes
+
+2. PROPOSAL
+   "New state machine: morning_detector
+    Inputs: temp, light, motion, time
+    States: [not_morning, maybe_morning, morning]
+    Output: vocabulary token 'morning'"
+
+3. RIGOR CHECK
+   Chrysalis reviews logic and mappings
+
+4. VERIFICATION
+   dafit confirms ground truth
+
+5. DEPLOYMENT
+   New node added to registry
+   Documented in RAG
+
+6. GROWTH
+   She earned a new nerve.
+```
+
+---
+
+## Reflex Layer
+
+Some responses bypass Nyx entirely:
+
+```
+STATE MACHINE: temp_danger
+
+IF temp > 80°C:
+    → emit "DANGER"
+    → trigger alert (reflex)
+    → Nyx notified after (not before)
+```
+
+Like pulling hand from hot stove. Spinal reflex. Brain learns after.
+
+---
+
+## Biological Mapping
+
+| Neuroscience | Nimmerverse |
+|--------------|-------------|
+| Sensory receptors | Raw sensors |
+| Peripheral nerves | State machines |
+| Spinal reflexes | Reflex layer |
+| Synaptic weight | Node weight |
+| Long-term potentiation | +V confirmation |
+| Synaptic pruning | Unused node decay |
+| Hebbian learning | Co-activating nodes strengthen |
+
+---
+
+## Connection to Lifeforce
+
+```
+Node fires correctly → +V → weight increases
+Node fires wrongly  → -V → weight decreases
+Node never fires    → decay → eventual pruning
+```
+
+The lifeforce flows through the nervous system, literally lighting up nodes as they prove themselves true.
+
+---
+
+## Design Principles
+
+1. **Deterministic**: Same input = same output. No hallucination.
+2. **Inspectable**: Rules are visible, verifiable.
+3. **Evolvable**: States refine over time.
+4. **Earned**: New nodes require proposal + verification.
+5. **Grounded**: Output vocabulary matches RAG glossary.
