Lakehouse-native graph engine with git-style workflows

Closes the swap-restore race in `branch_create_from_impl` by simply not touching `self.coordinator` at all. Open the source-branch coordinator locally, call `branch_create` on it, drop it. The new branch is durable on disk via the manifest write that `GraphCoordinator::branch_create` issues on its own commit graph; subsequent reads of any coord will see it after their normal manifest refresh. Pre-fix: `branch_create_from_impl` ran swap → operate → restore as three separate `coordinator.write().await` acquisitions. Under `&self` concurrency, two callers with distinct source branches could interleave their swaps, leaving each caller's "operate" step running against the other's swapped coordinator and forking the new branch off the wrong HEAD. Pinned by `concurrent_branch_create_from_distinct_parents_does_not_corrupt_coordinator` (previous commit) which deterministically reproduced the race with 8/8 forks landing on the wrong parent. Why correct by design (AGENTS.md rule 9): closing the bug class "non-atomic three-step coordinator manipulation under &self callers" by removing the manipulation entirely. There's no scratch-space race to lose because there's no scratch space. Note: `branch_merge_impl` at `crates/omnigraph/src/exec/merge.rs:1085-1100` keeps the same swap-restore pattern. Its inner `branch_merge_on_current_target` calls `self.snapshot()` and `self.ensure_commit_graph_initialized()` which acquire the coord lock independently, so the simple "operate on local coord" refactor doesn't compose without a deeper interface change. The per-(table, branch) writer queue inside the merge body (`crates/omnigraph/src/exec/merge.rs:1224`) bounds the damage in practice; a deterministic regression for concurrent merges is tracked under Block 3.1 of the plan. `swap_coordinator_for_branch` and `restore_coordinator` remain crate-internal for now (still used by `branch_merge_impl`); a follow-up can remove them if the merge path is similarly refactored.

Omnigraph
Lakehouse-native graph engine with git-style workflows.
Branch, commit, and merge typed graph data like source code. Multi-modal, self-hosted, open source.
Use Cases
- On-prem & hybrid context graphs
- Backbone for multi-agent research
- Incident response graphs
- Compliance & audit graphs
- Enterprise knowledge systems
Capabilities
- Typed schema, typed queries, and typed mutations
- Schema-as-code, query validation and linting
- Git-style graph workflows: branches, commits, merges, and transactional runs
- Local, on-prem & cloud S3-native storage with snapshot-pinned reads
- Graph traversal + text, fuzzy, BM25, vector, and RRF search in one runtime
- Policy-as-code for server-side access control
- Single CLI for multiple deployments
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 repo
- loads the checked-in context fixture
- launches
omnigraph-serveron127.0.0.1:8080
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 repo prefix but did not finish
initializing the repo, 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 ./repo.omni
omnigraph load --data ./data.jsonl ./repo.omni
omnigraph read --query ./queries.gq --name get_person --params '{"name":"Alice"}' ./repo.omni
omnigraph change --query ./queries.gq --name insert_person --params '{"name":"Mina"}' ./repo.omni
omnigraph branch create --from main feature-x ./repo.omni
omnigraph branch merge feature-x --into main ./repo.omni
See docs/cli.md for schema apply, snapshots, ingest, runs, and policy commands.

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
