# PROJECT B.R.A.I.N.

> A persistent, model-independent cognitive architecture with accepted Phase 6 capabilities.

**Boundary-governed Relational Archival & Invalidation Network** is a user-owned cognitive system. It keeps durable memory, document knowledge, evidence, authority, confidence, and correction history outside any single model provider.

> [!NOTE]
>
> **Current baseline:** The core text, Live, and document capabilities are accepted. Phase 7 is in progress: its technical prerequisites passed, and the required three-day genuine-use window is ready to begin. The system is not yet operational.

## What works today

* Teach a fact, end the session, recall it in a new session, explain its provenance, and correct it without erasing history.
* Use private Gemini Live text and raw-PCM voice through the same Conversation Gateway.
* Ingest supported PDF, DOCX, Markdown, and text sources with versioned artifacts and grounded citations.

## Ownership in one sentence

B.R.A.I.N. owns durable cognitive state; Gemini is a bounded, replaceable reasoning, Live, and embedding provider.
