Semantic Memory Architecture

Executive Summary

Semantic Memory Architecture defines how Algosure governs AI semantic memory, vector storage, embeddings, contextual retrieval, and Organizational Memory. Intelligence owns AI memory records and AIOS memory workflows, but it does not own operational source facts.

Why This Exists

AIOS and Digital Professionals need semantic retrieval across approved organizational context, documents, lessons, decisions, and evidence. Without governance, AI memory can leak tenant data, duplicate source facts, or become untraceable.

Owner

The owner is the Chief Product Officer and Enterprise Architect.

Business Value

Governed semantic memory improves AI usefulness while protecting tenant isolation, source attribution, explainability, retention, and human approval.

Memory Types

Memory Type	Ownership
Organizational Memory	Governed by Intelligence with source-domain attribution and tenant scope.
Semantic references	Intelligence-owned memory records that reference source facts or documents.
Embeddings	Intelligence-owned vector representations tied to source, tenant, classification, and retention metadata.
Reasoning records	Intelligence-owned AIOS reasoning, evidence, confidence, and explanation records.
Approved lessons learned	Learning or owning operational Domain as source, Intelligence as memory workflow owner.
AI-generated summaries	Owning operational Domain must accept source meaning; Intelligence owns generation metadata.

Semantic Memory Rules

Rule	Requirement
Intelligence owns memory records	Intelligence owns memory metadata, embeddings, retrieval records, and AIOS memory workflows.
Source Domains own source facts	Memory references do not transfer operational fact ownership to Intelligence.
Tenant isolation is mandatory	Vector records and retrieval must be tenant and organization scoped.
Source attribution is required	Every memory record must point to source Domain, document, event, or approved artifact.
Classification controls eligibility	Sensitive data requires explicit policy before indexing or retrieval.
Retention applies to memory	Memory records must expire, be reviewed, or be deleted according to retention and source lifecycle rules.
Human approval may be required	High-impact memory updates, cross-tenant learning, or sensitive summaries require approval where policy requires it.
