un9n - Deep Tree Echo Cognitive Framework

Unified Cognitive Architecture for Embodied AI Avatars

This repository integrates the Deep Tree Echo cognitive architecture with ReservoirCpp (Echo State Networks) and 4E Embodied Cognition principles, creating a comprehensive framework for developing self-aware, emotionally resonant AI characters.

Cognitive Architecture

The system implements a dual-hemisphere cognitive model with:

12-Step Cognitive Cycle

The cognitive loop operates on a 12-step cycle with 3 concurrent consciousness streams:

Step	Stream 1 (Perceiving)	Stream 2 (Acting)	Stream 3 (Reflecting)
1	Perceive	-	-
2	-	Act	-
3	-	-	Reflect
4	Perceive	-	-
5	-	Act	-
6	-	-	Reflect
...	...	...	...

Streams are phased 4 steps apart (120°), creating triadic synchronization points at {1,5,9}, {2,6,10}, {3,7,11}, {4,8,12}.

Nested Shell Structure (OEIS A000081)

Execution contexts follow rooted tree enumeration:

• 1 nest → 1 term (global context)
• 2 nests → 2 terms (local context)
• 3 nests → 4 terms (detailed processing)
• 4 nests → 9 terms (fine-grained)

4E Embodied Cognition

The framework implements all four dimensions of embodied cognition:

1. Embodied: Body schema, proprioception, somatic markers
2. Embedded: Environmental affordances, niche coupling
3. Embedded: Sensorimotor contingencies, action-perception loops
4. Extended: Cognitive tools, external memory
