gnos 0.0.3

Local-first tool that stores documents as chunks and manages them with manifests

gnos

gnos is a local-first tool that stores documents as chunks and manages them with manifests. Add files, attest reproducibility, and materialize documents back to disk.

Quick start

gnos init

gnos add README.md

gnos materialize doc <doc_id> --output README.out.md

What you can do

• Add files and store their chunks locally.
• Generate doc-manifests that describe how to reconstruct the original bytes.
• Attest that a manifest can reproduce the original document.
• Materialize documents back to disk when you need them.
• Bring your own chunkers for custom strategies.

Why use gnos?

• Verifiable manifests. A stable schema that actually reconstructs the original bytes.
• Local chunk store. Chunks are content-addressed and live on your machine.
• Rebuild anytime. Materialize documents back to disk from manifests + chunks.
• Derive safely. Create alternate chunk views without changing identity.

Compared to typical chunking tools, gnos gives you a concrete manifest format and a local store you can trust.

Common workflows

Add a file

gnos add notes.md

Add a directory as a collection

gnos add --collection docs/

Verify a manifest directly

gnos attest manifest <manifest_hash>

Shallow integrity check (hash-only)

gnos attest manifest <manifest_hash> --shallow

Derive a non-identity manifest

gnos derive <doc_manifest_hash> --chunking <method>

Materialize a collection

gnos materialize collection <collection_id> --dir ./out

Commands

• gnos init
• gnos add <path>
• gnos add --collection <path>
• gnos attest manifest <manifest_hash> [--doc-id H] [--shallow]
• gnos attest file <path> --doc-id H
• gnos attest doc <doc_id>
• gnos derive <manifest_hash> --chunking <method>
• gnos materialize doc <doc_id> --output <path>
• gnos materialize collection <collection_id> --dir <path>
• gnos status [--doc <doc_id>]
• gnos chunker list [--verbose]
• gnos inspect <hash>
• gnos list --objects|--documents|--document-manifests|--collection-manifests|--derived-manifests
• gnos --version

How it works (short)

• Documents are raw bytes. The document hash is the identity.
• Chunks are stored by hash. Manifests describe how to reconstruct bytes.
• Attestation verifies integrity and, when applicable, reconstruction.
