First slice of the schema-lint chassis. Adds stable `OG-XXX-NNN`
codes to schema-migration rejections so operators can suppress, look
up, and filter on identifiers rather than free-text prose. Atlas-style
chassis adapted to omnigraph's typed-IR substrate (no SQL injection
vector, no per-engine locks, native edge/vector/embedding types).
What's in v0:
- New `omnigraph-compiler/src/lint/` module with:
- `diagnostic.rs` — Family / SafetyTier / Severity enums covering ten
families (DS, MF, CD, BC, NM, OW, NL, VE, ED, LK). Only DS and MF
are populated in this PR.
- `codes.rs` — 8 DiagnosticCode constants (OG-DS-101..105,
OG-MF-103, OG-MF-104, OG-MF-106). Five of the eight are wired to
real emission sites; the other three are reserved.
- Unit tests for catalog invariants: codes unique, prefix matches
family, suffixes are 3-digit, destructive defaults to error,
lookup() works, EMITTED_IN_V0 codes exist in ALL_CODES.
- `SchemaMigrationStep::UnsupportedChange` gains an optional
`code: Option<String>` field. New `unsupported_error_message()`
helper prefixes the message with `[code]` when present.
- 5 of 17 existing rejection paths now carry codes:
- `removing node type` → OG-DS-102
- `removing edge type` → OG-DS-103
- `removing property` → OG-DS-104
- `adding required property without backfill` → OG-MF-103
- `changing property type` → OG-MF-106
Remaining 12 paths carry `code: None` and are tagged as future work.
- `schema_apply` surfaces the formatted error (with `[code]` prefix);
CLI `omnigraph schema plan` renders the code on the
`unsupported change on <entity>` line.
- PR #62 destructive-rejection tests in `tests/schema_apply.rs` now
assert on the stable code (`msg.contains("OG-DS-104")`) instead of
the error-message substring. 11/11 tests pass.
- New `docs/schema-lint.md` documents the v0 catalog + the 10 families
+ Atlas prior art. AGENTS.md index updated.
What's explicitly NOT in v0 (subsequent PRs):
- No severity config in `omnigraph.yaml` (MR-694 §2).
- No `@allow(OG-XXX-NNN, "rationale")` suppression directive (§3).
- No `--allow-data-loss` flag or destructive-tier enforcement.
- No new `SchemaMigrationStep` variants (soft/hard drops, default,
widen/narrow). MR-700, MR-697 land those.
- No pre-migration checks (MR-941).
- No CD / VE / LK / NM family rules (MR-942..945).
- No CI integration (MR-946).
Tests: 235 compiler tests, 11 schema_apply integration tests, 14
lint module tests, 55 CLI tests — all green.

Bundles the working-tree state from the prior session (PR 0 bench harness,
PR 1a audit_actor_id removal, PR 1b WriteQueueManager + writer integration)
together with the first half of PR 2's interior-mutability foundation
(catalog and schema_source wrapped in Arc<ArcSwap<...>>). The two streams
intermix in 7 of the same files, so splitting via git add -p was
impractical. Subsequent PR 2 steps land as separate atomic commits.
PR 0 — server-level concurrent /change bench harness
- crates/omnigraph-server/examples/bench_concurrent_http.rs (new)
- .context/bench-results/{baseline-main,after-pr1}/ (gitignored)
PR 1a — drop the audit_actor_id field, thread per-call
- removed Omnigraph::audit_actor_id and the swap-restore patterns in
mutation.rs, merge.rs, loader/mod.rs
- actor_id: Option<&str> threaded through MutationStaging::finalize,
mutate_with_current_actor, ingest_with_current_actor,
branch_merge_impl, branch_merge_on_current_target,
commit_prepared_updates*, record_merge_commit,
commit_updates_on_branch_with_expected
- apply_schema and ensure_indices_for_branch pass None (system-attributed)
PR 1b — per-(table_key, branch) write queue + revalidation + sidecar
- new crates/omnigraph/src/db/write_queue.rs with WriteQueueManager,
acquire/acquire_many, sorted+deduped acquisition; 6 unit tests
- Arc<WriteQueueManager> field on Omnigraph + db.write_queue() accessor
- MutationStaging::finalize split into stage_all (Phase A, no queue)
and StagedMutation::commit_all (Phase B, acquire_many + revalidate
pins + sidecar + commit_staged); guards held across publisher
- delete-only mutations now emit recovery sidecars; revalidation
extended to inline_committed tables
- branch_merge_on_current_target, apply_schema_with_lock, and
ensure_indices_for_branch acquire per-table queues for their
touched tables
PR 2 Step B (partial) — catalog and schema_source via ArcSwap
- catalog: Catalog -> Arc<ArcSwap<Catalog>>
- schema_source: String -> Arc<ArcSwap<String>>
- public accessors return Arc<Catalog> / Arc<String>; readers bind
locally where the borrow has to outlive an expression
- new pub(crate) store_catalog / store_schema_source helpers replace
the field assignments in apply_schema and reload_schema_if_source_changed
- 117 tests across lifecycle/end_to_end/branching/runs pass; engine
lib + workspace compile clean
Coordinator wrap (Mutex) and the &mut self -> &self engine API
conversion follow in subsequent commits.

OmniGraph is OSS; internal Linear ticket references and code-review-bot
mentions in source-code comments don't help external readers and leak
internal tooling. Replace ticket numbers (MR-XXX) with descriptive
prose, drop linear.app URLs, and remove inline mentions of
Cursor/Bugbot/Cubic/Codex review threads.
Scope is limited to source-code comments (`crates/`). Docs under
`docs/` keep their MR-XXX references — those are part of the
established change-history narrative for in-repo docs and don't
require a Linear account to find context for.
No behavior changes; no public API changes.

mutate_as and load now write directly to target tables and call the
publisher once at the end with per-table expected versions; the Run
state machine, _graph_runs.lance writers, __run__ staging branches,
and server /runs/* endpoints are removed. Multi-statement mutations
remain atomic at the manifest level via an in-memory MutationStaging
accumulator that gives read-your-writes within a query and a single
publish at the end. Concurrent-writer conflicts surface as
ExpectedVersionMismatch (HTTP 409 manifest_conflict) instead of the
old DivergentUpdate merge shape. Documents one known limitation in
docs/runs.md: a multi-statement mid-query failure where op-N writes
a Lance fragment and op-N+1 fails leaves Lance HEAD ahead of the
manifest until a follow-up introduces per-table Lance branches.

* 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).

Review feedback on #23, applied on top of the original commit:
- Rename the CLI subcommand from `schema get` to `schema show` to match
the existing `run show` / `commit show` convention. A `#[command(alias
= "get")]` preserves muscle memory for anyone who already typed `get`.
- Rename `SchemaGetOutput` → `SchemaOutput` and its field `source` →
`schema_source`, so the get response and the apply request use the
same field name for the same concept.
- Use `println!` instead of `print!` in the CLI so the shell prompt
doesn't land on the last line of schema output.
- Add three integration tests on `/schema`: happy path (no auth),
401 when bearer is required but missing, 403 when the policy grants
the actor branch_create but not read.
Follow-ups left for a separate PR: include `schema_ir_hash` and
`schema_identity_version` in the response payload so clients can do
drift detection and the server can set an ETag; and a fast-path local
read that skips `Omnigraph::open()` when only the schema source is
needed.

Exposes the existing schema_source() method via a new `omnigraph schema get`
CLI subcommand and a `GET /schema` API endpoint, allowing users to retrieve
the current accepted schema from any graph repository.
