fix(optimize): reconcile pre-existing benign HEAD>manifest drift on empty plan
When a table has nothing left to compact but its Lance HEAD is ahead of the
manifest pin, optimize now catches the manifest up to HEAD (a single CAS-guarded
__manifest commit, no Lance HEAD movement, so no recovery sidecar). This heals
drift left by a pre-fix optimize or an external raw compact_files, so strict
writes / schema apply stop 409ing with "stale view".

Safe by construction: the pending-sidecar defer guard at the top of
optimize_all_tables already ensures no recovery sidecar is in flight, so any
HEAD>manifest reaching this branch is benign and content-preserving — never a
partial write the recovery sweep would roll back. This is the producer-side
heal for uncovered (legacy/external) drift; the write path stays strict and the
recovery protocol's no-drift assumption is preserved (no consumer tolerance).

Restores the reconcile branch removed alongside the (now-abandoned) consumer
tolerance approach; the defer guard added in the same cycle is what makes it
safe to keep.

License: MIT Rust Crates.io CI

Lakehouse native graph engine built for context assembly

Omnigraph acts as operational state & coordination layer for agents

  • Git-style versioning & branching
  • Multimodal retrieval (graph+vector/fts+filters) optimized for context assembly
  • Object storage native (S3, RustFS)
  • Native blob-as-data support (docs, images, videos, etc)
  • VPC, On-prem, hybrid deployment
  • Lance format as open storage layer
AS CODE What it means
Schema AS CODE Typed .pg schemas, planned, applied, enforced
Context AS CODE Linted queries & agentic nudges, versioned and reusable
Security AS CODE Cedar policies enforced server-side on every mutation
Dashboards AS CODE Declarative views & controls over the graph (coming)

Core Use Cases

Use case What it's for
Company brain Org knowledge unified into one queryable graph
Context graph Decision traces and codified tribal knowledge
Agentic memory Durable, versioned memory for long-running agents
Dev graph Issues & dependency model for coding agents
R&D data layer Experiments & trials data written into branches
ML workflows Versioned, branchable graphs for training & eval
Karpathy's LLM wiki A living, agent-updatable knowledge base

Quick Install

curl -fsSL https://raw.githubusercontent.com/ModernRelay/omnigraph/main/scripts/install.sh | bash

This installs omnigraph and omnigraph-server into ~/.local/bin from published release binaries.

Or install with Homebrew:

brew tap ModernRelay/tap
brew install ModernRelay/tap/omnigraph

For starter graphs and agent skills to bootstrap and operate Omnigraph, see ModernRelay/omnigraph-cookbooks.

One-Command Local RustFS Bootstrap

curl -fsSL https://raw.githubusercontent.com/ModernRelay/omnigraph/main/scripts/local-rustfs-bootstrap.sh | bash

That bootstrap:

  • starts RustFS on 127.0.0.1:9000
  • creates a bucket and S3-backed graph
  • loads the checked-in context fixture
  • launches omnigraph-server on 127.0.0.1:8080

Docker must be installed and running first.

The RustFS bootstrap prefers the rolling edge binaries and only falls back to source builds when release assets are unavailable.

If a previous run left objects under the same graph prefix but did not finish initializing the graph, rerun with RESET_REPO=1 or set PREFIX to a new value.

Common Commands

The same URI works for local paths, s3://…, or http://host:port.

omnigraph init   --schema ./schema.pg ./graph.omni
omnigraph load   --data   ./data.jsonl ./graph.omni
omnigraph read   --query  ./queries.gq --name get_person --params '{"name":"Alice"}' ./graph.omni
omnigraph change --query  ./queries.gq --name insert_person --params '{"name":"Mina"}' ./graph.omni
omnigraph branch create --from main feature-x ./graph.omni
omnigraph branch merge  feature-x --into main ./graph.omni

See docs/user/cli.md for schema apply, snapshots, ingest, commits, and policy commands.

Clients

For programmatic access to a running omnigraph-server:

  • TypeScript SDK@modernrelay/omnigraph (source). Instance-per-client, typed errors, camelCase types, async-iterator streaming export.

    npm install @modernrelay/omnigraph
    
  • Model Context Protocol server@modernrelay/omnigraph-mcp (source). Bridges Omnigraph to LLM hosts (Claude Desktop, Claude Code, …) over stdio. Exposes tools and resources for schema, branches, queries, mutations, ingest, and bundles curated best-practices guidance from the cookbook.

    npm install -g @modernrelay/omnigraph-mcp
    

Both packages are versioned in lockstep with omnigraph-server on major.minor: @modernrelay/omnigraph@X.Y.* targets omnigraph-server@X.Y.*. See ModernRelay/omnigraph-ts for the monorepo.

Build And Test

cargo build --workspace
cargo check --workspace
cargo test --workspace

Notes:

  • Rust stable toolchain, edition 2024
  • CI runs cargo test --workspace --locked
  • Full CI and some local test flows require protobuf-compiler
  • S3 integration tests expect an S3-compatible endpoint such as RustFS

Workspace Crates

  • crates/omnigraph-compiler: shared schema/query parser, typechecker, catalog, and IR lowering
  • crates/omnigraph: storage/runtime, branching, merge, change detection, and query execution
  • crates/omnigraph-cli: CLI for graph lifecycle (init/load/ingest), query/mutate, branch/commit/merge, schema/lint, snapshot/export, policy, and maintenance (optimize/cleanup)
  • crates/omnigraph-server: Axum HTTP server for remote reads, changes, ingest, export, branches, and commits
