Core Concepts

Brain Instances

Isolated persistent intelligence layer with:

• Domain-specific configuration
• 33 baseline entries created on initialization

Memory Rings

Three persistence tiers:

1. Session Ring: Resets per session_id
2. Entity Ring: Persists by entity_id
3. Institutional Ring: Permanent org-scoped with ltree address keys

Intent Classification

11 intent types:

• specification | change_request | diagnosis | verification
• risk_assessment | retrospective | planning | knowledge_retrieval
• compliance_check | knowledge_ingestion | intent_clarification

Address key format: intent_type.scope.domain.specificity (exactly 4 levels)

Confidence Scoring

• 0-100 score with gate decisions:
  • pass (≥80)
  • review (50-79)
  • block (<50)
• Coverage Map tracks entry count per address key

The Calibrator

• Runs during consolidation windows
• Derives Scorer rule weights
• Writes to branch and root keys only
• Leaf entries immutable
• Cross-validation rollback on worse performance
