DOM GraphRAG & Sovereign Local Hybrid RAG Workbench

Dual-plane retrieval cockpit: interrogate 980 public Curriculum-as-Code DOM GraphRAG nodes in any browser, or connect over 127.0.0.1 loopback from M1/M2 macOS to search and synthesize across your air-gapped SQLite FTS5 + 768-dim Ollama Carbon 4 vault.

In Plain English • Cognitive Accessibility Callout

Before you read the details below, here is the short version: DOM GraphRAG and Sovereign Hybrid RAG find exact facts across thousands of documents without uploading private files to the cloud. Public visitors can search 980 open Exercise Science curriculum nodes right in their browser, while Coach Alan's M1 and M2 Macs pair locally over 127.0.0.1:8766 to query private scans and records. That keeps veteran, legal, and academic files 100% private at zero monthly cloud cost.

En palabras sencillas: Es como tener un archivo blindado en tu propio escritorio donde encuentras cualquier documento o regla clínica en segundos sin subir papeles privados a internet. Si los términos técnicos se ponen pesados, concéntrate primero en elegir una pregunta de ejemplo abajo y revisar las fuentes verificadas que te devuelve el buscador.

Sovereign M1/M2 Local Hybrid RAG Cockpit (127.0.0.1:8766)

Zero-Residue Loopback Security Gate (Active on Coach Alan's M1 & M2 Macs)

By design, zero bytes of the private Carbon 4 SQLite vault (Epson WF-4830 legal/credential scans, VetCert records, and local repositories) are ever stored on GitHub Pages or any remote server.

On Coach Alan's M1 or M2 Mac: Double-click Sovereign Hybrid RAG.command on your macOS Desktop (or run make rag-ui inside ~/projects/carbon4-ecosystem). It starts the local loopback server strictly on 127.0.0.1:8766 and opens this cockpit with an ephemeral RFC 3986 URL fragment token (#token=...) that is never transmitted over HTTP.

make -C ~/projects/carbon4-ecosystem desktop-shortcut && open ~/Desktop/"Sovereign Hybrid RAG.command"

Manual Local Token: Open Pure Offline Mirror (127.0.0.1:8766)

How This Dual-Plane Hybrid RAG Architecture Works

Plane 1 — Open Curriculum-as-Code DOM GraphRAG: Distills HTML/Markdown DOM hierarchy (Course → Module → H2/H3 Section → Clinical Role), Pattern / Rule / Solve clinical framing tags, and W3C PROV-O SHA-256 content hashes into an inspectable static index with zero server runtime cost.
Plane 2 — Air-Gapped Apple Silicon Sovereign Vault (127.0.0.1:8766): Fuses exact lexical citations via SQLite FTS5 (BM25) with 768-dimensional dense semantic vectors via local Ollama nomic-embed-text:latest using Reciprocal Rank Fusion (RRF, k=60), then synthesizes grounded answers inside ### prompt-isolation delimiters via exw-carbon4:latest.
Zero-Residue Security Boundary: The M1/M2 Desktop Shortcut passes an ephemeral bearer key via RFC 3986 URL hash fragment (#token=...), which browsers never transmit to remote HTTP hosts, and talks exclusively to 127.0.0.1:8766 via W3C Private Network Access headers.
