tier: Tier-6-System
category: System-Architecture
tags: [adr, compliance, worm, self-healing, rag, service-email, service-content]
abstract: |
  Decision record establishing the physical separation between compliance artifacts and active intelligence pools. Prevents Context Window Collapse in Retrieval-Augmented Generation (RAG) pipelines.
details:
  the_compliance_layer:
    component: service-email
    role: "The immutable record. Stores raw communications as independent Maildir files. Mathematically WORM (Write-Once-Read-Many). Forbidden from modification to ensure audit and legal validity."
  the_intelligence_layer:
    component: service-content
    role: "The self-healing holding tank. Stores extracted, plain-text facts in a localized knowledge graph. Continuously mutates, appends, and replaces historical facts with current truths to provide clean, noise-free context to language models."
  the_bridge:
    component: service-slm
    role: "The headless filter. Reads the compliance layer, extracts the intelligence, and writes exclusively to the self-healing layer."
