lex-attention

Selective attention filter for the LegionIO brain-modeled cognitive architecture.

What It Does

Models the thalamic reticular nucleus and prefrontal attention systems. Filters and prioritizes incoming signals before they enter the cognitive pipeline. Implements spotlight attention, goal-directed amplification, habituation, and capacity limits.

client = Legion::Extensions::Attention::Client.new

# Filter incoming signals
result = client.filter_signals(
  signals: [
    { salience: 0.9, domain: :terraform, novelty: 0.8 },
    { salience: 0.1, domain: :heartbeat, novelty: 0.0 },
    { salience: 0.5, domain: :vault, novelty: 0.6 }
  ],
  active_wonders: [
    { domain: :terraform, salience: 0.7 }
  ]
)
# => { filtered: [...], spotlight: 1, peripheral: 1, background: 0, dropped: 1 }

# Manual focus
client.focus_on(domain: :security, reason: 'incident response')
client.attention_status

Attention Tiers

Tier	Score Range	Meaning
:spotlight	>= 0.7	Full cognitive processing
:peripheral	>= 0.4	Reduced processing, may promote
:background	>= 0.2	Minimal processing, logged
:filtered	< 0.2	Dropped entirely

Key Features

• Habituation: Repeated signals in same domain become less salient
• Goal amplification: Signals related to active curiosity wonders get boosted
• Capacity limit: Max 7 spotlight items (Miller's law)
• Manual focus: Direct attention to specific domains
