Lakehouse-native graph engine with git-style workflows

Three bundled changes:
1. Rename `tests/agent_lifecycle.rs` -> `tests/composite_flow.rs` (and
the test function). OmniGraph is consumed by both humans and agents
- naming the test after one audience misframes the library.
2. Strip Linear ticket IDs, PR numbers, bot reviewer names, and
review-round labels from source, tests, and docs added by this
branch. Internal traceability belongs in commit messages and PR
descriptions, not in checked-in artifacts. Upstream
lance-format/lance issue refs and pre-existing MR-XXX refs in docs
not touched by this branch are left alone.
3. Two outstanding review findings addressed:
- `needs_index_work_node` / `needs_index_work_edge`: propagate
`count_rows` errors instead of `unwrap_or(0)`. Silently treating
transient I/O failures as "0 rows" risked skipping a table from
the recovery sidecar pin set that was actually about to be
modified.
- `recovery_multi_sidecar_requires_fresh_snapshot_for_correctness`:
strengthen the assertion to fail when sidecar B classifies under
a stale snapshot. The new assertion checks post-recovery Lance
HEAD == v3 (no `Dataset::restore` ran). The previous "sidecar
deleted + audit rows present" pair passed in both the bug and
fix paths because both delete the sidecar and write an audit
row; the differentiator is the post-recovery HEAD. Strengthening
the assertion exposed an additional nuance: in this overlapping-
sidecar scenario sidecar B's audit kind is RolledBack (no-op)
rather than RolledForward, since sidecar A's roll-forward
publishes Lance HEAD as the new manifest pin (absorbing B's
work). The docstring now explains why this is correct given
current `roll_forward_all` semantics.
All workspace tests pass with --features failpoints.

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
