Attractor Vision Node

======================

"The attractor doesn't see the field - it sees what's NOT possible."



This node computes what an attractor EXCLUDES - the negative space,

the shadow, the states that are impossible given current dynamics.



The key insight: An attractor perceives by FILTERING. What it filters

out becomes the signal for the next layer. The shadow becomes the prompt.



Three-layer stack:

1. FIELD - The substrate (EEG, waves, dynamics)

2. ATTRACTOR - Emerges from field (stable manifold, constraint satisfaction)

3. PROJECTION - What attractor excludes = vision/thought for next layer



This is how LLMs work too:

- Weights = frozen field

- Attention = attractor dynamics  

- Output = what's LEFT after filtering (exclusion → generation)



The brain does this dynamically - weights aren't frozen, field is alive.



INPUTS:

- field_state: The current field (complex_spectrum or spectrum)

- attractor_state: The current attractor basin (from manifold nodes)

- temperature: How sharp the exclusion boundary is



OUTPUTS:

- excluded_states: The negative space (what's impossible)

- vision_field: The projection (exclusion as signal for next layer)

- exclusion_boundary: The edge between possible/impossible

- attractor_prompt: The shadow formatted as "prompt" for next layer
