Lakehouse-native graph engine with git-style workflows

The bot-review pass and the subsequent coverage audit surfaced two material gaps in PR #119's test surface — both easy to close, both worth closing before merge. * **Gap 1 — cluster-route sweep.** The Bug-1 path-extractor regression slipped through because `cluster_routes_dispatch_per_graph_handle` only exercised `/snapshot`. The other six protected cluster routes (`/read`, `/change`, `/export`, `/schema`, `/schema/apply`, `/ingest`, `/branches/merge`) were implicitly trusted to work without any multi-mode integration test. Add `all_protected_cluster_routes_resolve_to_their_handler` (`tests/server.rs`) that hits each protected cluster route with a minimal request and asserts the response is consistent with the handler being reached — no 404 (router didn't match), no 500 with "Wrong number of path arguments" (Bug-1 class), no 500 with "missing extension" (routing middleware didn't inject the handle). Status code is a negative assertion because each handler's happy-path inputs differ; what matters is "the request reached the handler," not "the handler returned 200" — that's already pinned by the single-mode tests. * **Gap 2 — `--force` happy path.** The strict re-init regression test (`init_on_existing_graph_uri_does_not_destroy_existing_schema`) pins the error path; nothing pinned the `force: true` escape hatch actually doing what its docstring claims. Add `init_with_force_recovers_from_orphan_schema_files` (`tests/lifecycle.rs`). Writes a bare `_schema.pg` to simulate orphan files from a failed prior init, confirms strict mode bails as expected, then confirms `init_with_options(force: true)` succeeds and produces a functional graph. Note: the test follows the documented semantics — force skips the preflight only, it does NOT purge existing Lance state. An earlier draft of the test (against full overwrite of an existing populated graph) failed because `GraphCoordinator::init` errored on the existing `__manifest`, which is exactly the limitation the `InitOptions::force` docstring already calls out. Recursive purge needs `StorageAdapter::delete_prefix` (tracked separately). Coverage is now fully aligned with the PR's claims. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Omnigraph
Object-storage native knowledge graph with git-style workflows. Designed for agents and humans to collaborate on shared structured knowledge.
Turns fragmented context into a live graph, lets humans and agents coordinate through that graph, and uses branches so agent-generated changes can be reviewed and merged safely.
Built on Rust, Arrow, DataFusion and Lance.

Use Cases
- Company brain / Second brain
- Context graph
- Knowledge base for multi-agent research
- Incident response graph
- Compliance & audit graph
Capabilities
- Typed schema, typed queries, and typed mutations
- Native blob-as-data support (docs, images, videos, etc)
- 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 graph
- 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 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, 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
