PR 9 — the final integration PR for MR-668 multi-graph server work.
Closes the v0.7.0 release.
Composite lifecycle tests (closes gaps flagged in PR 7's coverage
review):
- `multi_graph_lifecycle_post_query_restart_persistence` — POST a
graph, query it via cluster route, reload the config from disk
and confirm `load_server_settings` sees the rewritten YAML.
Validates the "restart resolves orphans" failure-mode story.
- `per_graph_policy_enforced_on_post_created_graph` — POST a graph
with a per-graph policy attached, then send authenticated read
and change requests. Per-graph Cedar enforcement fires correctly
on a POST-created graph (engine-layer policy reinstalled via
`Omnigraph::with_policy` inside the create flow).
- `concurrent_post_graphs_distinct_ids_all_succeed` — 4 concurrent
POSTs with distinct graph_ids all return 201. Caught a real
race in `rewrite_atomic` (see below).
Race fix — `rewrite_atomic_with_modify`:
The first composite test surfaced a real bug. The old
`rewrite_atomic(path, new_config, expected_hash)` captured the
baseline hash OUTSIDE the flock, then called rewrite_atomic which
re-acquired it inside. Under concurrent writers:
- POST A: captures baseline H0, calls rewrite_atomic.
- POST B: captures baseline H0 too (before A's update lands).
- A: acquires flock, on-disk == H0, writes H1, releases.
- A: updates baseline H0 → H1.
- B: tries to acquire flock — waits.
- B: acquires flock. On-disk is now H1. Expected (captured
before A finished) is H0. MISMATCH → spurious Drift error.
Worse: even if the timing happens to align, B's `updated` config
was constructed from BYTES read before the flock. B writes a config
that doesn't include A's new graph — silent data loss.
The fix: new `config::rewrite_atomic_with_modify(path, baseline,
modify)` takes a closure. Inside the flock + baseline mutex:
1. Read on-disk bytes, hash, compare to baseline.
2. Parse on-disk YAML.
3. Call `modify(parsed)` to produce the new config — receives
fresh on-disk state, returns the modification.
4. Serialize + write + fsync + rename + update baseline.
Everything is read-modify-write under the same critical section.
Concurrent writers serialize cleanly. Test confirmed this is no
longer a race.
The old `rewrite_atomic(path, new_config, expected_hash)` API stays
for tests that don't need the read-modify-write shape; the POST
handler switches to the new shape.
Version bump v0.6.0 → v0.7.0:
- All 5 `crates/*/Cargo.toml` (compiler, engine, policy, cli, server)
plus their inter-crate `path` dep version constraints.
- `Cargo.lock` regenerated by `cargo build --workspace`.
- `AGENTS.md` "Version surveyed" line, capability matrix HTTP-server
row updated to mention multi-graph + cluster routes + atomic YAML
rewrite.
- `openapi.json` regenerated.
Docs:
- `docs/releases/v0.7.0.md` (new) — release notes with breaking
changes, new features, deferred items (DELETE, `delete_prefix`,
actor forwarding), and the single→multi migration recipe.
- `docs/user/server.md` — substantial section additions for the
two modes, mode inference, cluster endpoint table, management
endpoints, `omnigraph.yaml` ownership contract, `POST /graphs`
body shape + status codes.
- `docs/user/cli.md` — `omnigraph graphs list/create` section,
deferred-DELETE note.
- `docs/user/policy.md` — server-scoped Cedar actions
(`graph_create`, `graph_list`), per-graph vs server-level policy
composition, example server-level policy.
Workspace test pass: 573 tests green across all crates. Zero
failures. MR-731 spoof regression still pinned and passing across
the entire 10-PR series.
This commit closes MR-668. v0.7.0 is ready for tagging.

* gitignore: exclude docs/internal/ from publication
Mirrors the existing "Local-only working files (not for the public
repo)" pattern. Working notes filed under docs/internal/ stay on the
contributor's machine instead of cluttering the published doc tree
or tripping the AGENTS.md / docs-index cross-link check
(scripts/check-agents-md.sh enumerates every docs/*.md and requires
each one to be linked from an audience index — internal notes don't
have an audience index by definition).
Incidental to the v0.5.0 release; lands separately from the version
bump commits.

* ci: skip docs/internal/ in agents-md cross-link check
Matches the .gitignore exclusion. Mirrors the existing 'docs/releases/'
exclusion pattern: notes under docs/internal/ aren't part of the
published doc tree and don't need to be linked from an audience index.

* release: v0.5.0 — Lance 6 substrate, Cedar policy engine, schema-lint v1
Bumps the workspace from 0.4.2 to 0.5.0. Release notes at
docs/releases/v0.5.0.md.
Three user-visible pillars motivate the minor bump:
1. Lance 6.0.1 substrate (DataFusion 52→53, Arrow 57→58)
2. Engine-wide Cedar policy enforcement on every _as writer; server
defaults to deny-all; signed-token-claim-only actor identity
3. Schema-lint v1 chassis: OG-XXX-NNN codes, soft drops, and
`--allow-data-loss` (Hard mode) for destructive migrations
Plus structured DataFusion Expr filter pushdown (unblocks
CompOp::Contains via array_has), HTTP allow_data_loss parity, inline
.gq sources on CLI/HTTP, optional CORS layer, and bug fixes
(merge-insert dup-rowid, branch-merge coordinator restore on error,
blob columns in branch merge).
Sites bumped:
- 5 crate [package].version lines (omnigraph, omnigraph-cli,
omnigraph-compiler, omnigraph-policy, omnigraph-server)
- 10 internal path-dep `version = "..."` constraints across the
four manifests that depend on sister crates (engine, server, cli,
plus engine's dev-dep on the compiler)
- Cargo.lock (regenerated via cargo update --workspace)
- AGENTS.md "Version surveyed:"
- openapi.json `info.version` (regenerated via
OMNIGRAPH_UPDATE_OPENAPI=1 cargo test -p omnigraph-server --test
openapi)
Verification:
- cargo test --workspace --locked: 907/907 green
- cargo test -p omnigraph-engine --test failpoints --features
failpoints: 19/19 green
- cargo test -p omnigraph-engine --test lance_surface_guards: 3/3
- scripts/check-agents-md.sh: clean

* Parallel per-type load writes + omnigraph optimize/cleanup CLI
## MR-677.3 — parallel per-type load writes
The load path already groups records into one RecordBatch per type and
makes one Lance commit per table (loader::mod.rs:249-..), but those
commits ran sequentially. Wrap node and edge write loops in
`futures::stream::buffered(N)` against a new helper
`write_batches_concurrently`. Concurrency tunable via
`OMNIGRAPH_LOAD_CONCURRENCY` (default 8).
## MR-676 — `omnigraph optimize` and `omnigraph cleanup`
New CLI subcommands that walk every node + edge table in the repo:
- `omnigraph optimize <uri>` — runs Lance `compact_files` on each
table to merge small fragments into fewer larger ones.
- `omnigraph cleanup <uri> --keep N | --older-than 7d --confirm` —
runs Lance `cleanup_old_versions` to prune historical manifests +
unique fragments. Requires `--confirm` because it's destructive.
Supports both count-based and time-based retention (or both AND'd
together). Time uses chrono `DateTime<Utc>` (added as a workspace
dep, default-features off).
Both commands run their per-table loops in parallel (8-way bounded,
`OMNIGRAPH_MAINTENANCE_CONCURRENCY` env override). Smoke-tested
against the 114-table prod graph: optimize went 7m15s sequential
→ 1m28s parallel. cleanup --keep 1 removed 137 historical versions
across 114 tables in 1m57s without disrupting `/healthz` or query
responses.
Public API on `Omnigraph`:
pub async fn optimize(&mut self) -> Result<Vec<TableOptimizeStats>>
pub async fn cleanup(&mut self, opts: CleanupPolicyOptions)
-> Result<Vec<TableCleanupStats>>
All 10 existing loader tests still pass.
Closes MR-676.
Partially addresses MR-677 (the .3 — parallel by type — piece;
MR-677.1 is for the `omnigraph embed` path, not load, since load
doesn't call Gemini directly. .2 was already in place).
