# Hybrid Memory Architecture

# Hybrid Memory Architecture

> A system design where a structured database serves as the immutable source of truth, used to dynamically generate disposable, human-readable wiki pages as a presentation layer.

## The Resolution

The **Hybrid Memory Architecture** is the proposed solution to the Wiki vs. Database dichotomy. It posits that a system must **separate storage from synthesis**.

## Authority Hierarchy

From [[quote-database-is-truth]]:

> *The database is truth, wiki is presentation layer.*

1. **Foundation — Structured Database** ([[concept-openbrain-architecture]]): the immutable, single source of truth, storing raw facts, metadata, and provenance.
2. **Middle Layer — [[concept-context-graph]]**: an automated agent maps relationships, dependencies, and contradictions between data points.
3. **Presentation Layer — AI Wiki**: a compiler agent runs on a schedule (or on demand) to generate human-readable markdown wiki pages.

## Why This Wins

- The wiki is *disposable*: if it drifts ([[concept-wiki-staleness]]), hallucinates ([[concept-error-baking]]), or experiences a [[concept-race-conditions-ai]], it is simply deleted and regenerated from the pristine database.
- Multi-agent scalability of a database with the narrative readability of a wiki.
- Preserves [[concept-silent-contradictions]] in the source layer while still allowing them to be surfaced narratively.

## Operationalized

The operational steps are formalized in [[framework-hybrid-memory-stack]] and the engineering action is captured in [[action-build-hybrid-system]].
