# Gateway Architecture: The Sensory Preprocessing Layer
**The Thalamus Pattern — routing sensory input to the appropriate processing tier.**
---
## Overview
The Gateway is the sensory preprocessing layer that sits between raw sensors and cognitive processing. It performs **routing, not translation**. Translation happens at each tier in its native format (numbers, states, vectors, JSON).
**Core Principle:** *Cheap operations handle common cases. Expensive operations handle rare cases.*
```
RAW SENSORS → GATEWAY (routing) → TIER → PROCESSING → (escalate?) → FUNCTION GEMMA → YOUNG NYX
↑ ↑ ↑ ↑
"which tier?" native format if needed structured JSON
```
**Key Insight:** Most sensory input NEVER becomes vocabulary. It stays as numbers, states, vectors. Only when it reaches Young Nyx (via Function Gemma) does it become structured text.
---
## The Problem We're Solving
### Old Model (Vocabulary Bottleneck)
```
RAW SENSOR → STATE MACHINE → VOCABULARY TOKEN → Young Nyx
Problems:
- Every input forced through text translation (expensive)
- LLM sees raw sensor dumps (noisy, unstructured)
- No economic pressure on routing (everything costs the same)
- Vocabulary conflated with routing decisions
```
### New Model (Tiered Gateway)
```
RAW SENSOR → GATEWAY → TIER 0-2 (numbers/states, no text)
→ TIER 3 (vectors via T5Gemma2)
→ FUNCTION GEMMA (structured JSON)
→ TIER 4 Young Nyx (clean typed events)
Benefits:
- Most input handled without LLM involvement
- Text only at cognitive boundary
- Economic pressure drives efficiency
- Routing separated from translation
```

## The Unified Tier Model
All existing tier systems in the architecture express the same principle:
| System | Document | Principle |
|--------|----------|-----------|
| Reward Tiers | `Cellular-Architecture.md` | Higher tier = more reward, more cost |
| Attention Levels | `Attention-Flow.md` | Higher priority preempts lower |
| Escalation Ladder | `organisms/Swarm-Evolution.md` | Higher = more authority, more cost |
| Reflex Homes | `Endgame-Vision.md` | Lower = faster, less capable |
| LOD Levels | `Endgame-Vision.md` | Lower = more detail, more cost |
### The Unified Tier Stack

## Node Weight Determines Tier
The node weight from `Nervous-System.md` directly maps to tier routing:
```python
@dataclass
class NervousNode:
"""A node in the nervous system's 4D space."""
position: tuple[float, ...] # Coordinates in sensory space
weight: float = 0.1 # Confidence from verification (0.0 → 1.0)
@property
def handling_tier(self) -> int:
"""Which tier handles this node's firing?"""
if self.weight >= 0.8:
return 0 # Hardware reflex - instant, bypass brain
elif self.weight >= 0.6:
return 1 # Math cell - fast, minimal checking
elif self.weight >= 0.3:
return 2 # Fast nerve - coordination, some deliberation
else:
return 3 # Escalate - needs organ/cognitive help
@property
def lifeforce_cost(self) -> float:
"""Cost scales inversely with confidence."""
return (1.0 - self.weight) * 10.0
```
**The key insight:** A mature node (weight ~1.0) naturally becomes a Tier 0 reflex. A new node (weight ~0.1) naturally escalates to higher tiers. The system learns which tier is appropriate through experience.
---
## The Gateway: Weight-Aware Router
The Gateway performs three functions:
| Function | Question | Cost |
|----------|----------|------|
| **Node Matching** | Which node(s) in 4D space match this input? | ~0 LF |
| **Weight Routing** | Based on weight, which tier handles it? | ~0 LF |
| **Anomaly Detection** | Is this novel, ambiguous, or contextually wrong? | Variable |
### Gateway Logic
```python
def gateway_route(sensory_input: dict) -> GatewayDecision:
"""Route sensory input to appropriate tier."""
# 1. Find candidate nodes in 4D space
candidates = nervous_system.find_nearby_nodes(sensory_input)
# 2. Handle edge cases
if len(candidates) == 0:
# NOVEL: No node matches this input
return GatewayDecision(
action="ESCALATE",
tier=4, # Young Nyx must see this
reason="novel_input",
cost=20.0,
)
if len(candidates) > 1:
# AMBIGUOUS: Multiple nodes could fire
best = max(candidates, key=lambda n: n.weight)
if best.weight < 0.5:
return GatewayDecision(
action="ESCALATE",
tier=3, # Organ inference to disambiguate
reason="ambiguous_input",
cost=8.0,
)
# 3. Single match - route based on weight
node = candidates[0]
# 4. Check for contextual anomaly
if detect_contextual_anomaly(node, sensory_input):
return GatewayDecision(
action="ESCALATE",
tier=node.handling_tier + 1,
reason="contextual_anomaly",
cost=node.lifeforce_cost * 1.5,
)
# 5. Normal routing
return GatewayDecision(
action="FIRE",
tier=node.handling_tier,
node=node,
cost=node.lifeforce_cost,
)
```
### Anomaly Detection Tiers
Anomaly detection itself is tiered:
| Level | Detection Type | Cost | Example |
|-------|---------------|------|---------|
| Tier 0 | Threshold | ~0 LF | Value out of physical range |
| Tier 1 | Statistical | ~0.3 LF | Value unusual for time of day |
| Tier 2 | Contextual | ~2 LF | Firing inconsistent with recent history |
| Tier 3 | Semantic | ~8 LF | Embedding distance from expected cluster |

## Function Gemma: The Structured Boundary
Function Gemma acts as the translation layer between lower tiers and cognition. It guarantees:
- **Schema compliance**: Every event follows a typed contract
- **Predictable JSON**: No hallucination, no free-form text
- **Bidirectional**: Sensors → JSON events, Decisions → JSON commands

## Example: crawler_gen_0 Light Seeking
### Early Learning (Low Weight)
```
Photoresistor reads 0.12 (was 0.73)
GATEWAY: node weight = 0.4 (learning)
Route to Tier 2 (nerve level)
Nerve detects: delta = -0.61 (significant!)
Nerve state: SEEKING → LOST_LIGHT
ESCALATE to Function Gemma
Function Gemma: { "event_type": "light_lost", ... }
Young Nyx: "spiral search pattern"
Function Gemma: { "command": "motor_spiral", ... }
NATS → motor cells execute
```
### After Learning (High Weight)
```
Photoresistor reads 0.12 (was 0.73)
GATEWAY: node weight = 0.85 (mature reflex)
Route to Tier 0 (hardware reflex)
REFLEX: light_lost → spiral_search (instant!)
Nyx notified AFTER (async, non-blocking)
```

## Design Principles
1. **Routing, not translation** — Gateway decides WHERE, not WHAT
2. **Weight determines tier** — Confidence from experience drives routing
3. **Text is expensive** — Reserve for cognitive boundary only
4. **Function Gemma guarantees structure** — No hallucination at the boundary
5. **Most input never escalates** — Reflexes handle common cases
6. **Anomalies always escalate** — Novel situations get attention
7. **Learning moves behavior down** — Tier 4 patterns become Tier 0 reflexes
