Add the scaffolding for the in-memory staged-write rewire — no behavior
change yet:
* New crates/omnigraph/src/exec/staging.rs with MutationStaging,
PendingTable, PendingMode, StagedTablePath, plus the end-of-query
finalize() that issues one stage_* + commit_staged per pending
table (Merge mode dedupes by id, last-write-wins).
* TableStore::scan_with_pending and count_rows_with_pending helpers —
Lance scan committed + DataFusion MemTable scan pending, concat.
Sidesteps the Scanner::with_fragments filter-pushdown limitation
documented on scan_with_staged.
* Add datafusion = "52" to workspace + omnigraph-engine deps for
MemTable (transitively pulled by Lance already).
Engine code still uses the legacy MutationStaging shape; the rewire
lands in subsequent commits.

Per-request ULID minted at the edge, exposed in request extensions and
on the response header. Caller-supplied X-Request-Id is echoed when
well-formed (1..=128 ASCII printable characters); otherwise rejected
and replaced with a fresh ULID so the value is always safe to log.
Companion to the TypeScript SDK redesign — clients now correlate logs
across the wire by reading X-Request-Id from response headers (and the
SDK already surfaces it on every OmnigraphError as `requestId`).
No spec change required; the header is a transport-layer concern.
Tests:
- mint a ULID when no header is provided
- echo a valid caller-supplied id
- reject overlong header (200 chars), mint a fresh ULID

* 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).

Introduces an opt-in AWS Secrets Manager backend for bearer tokens,
behind the `aws` Cargo feature. Default builds (on-prem, local dev)
don't pull in the AWS SDK and don't pay its compile cost.
- New Cargo feature `aws` gates the `aws-config` + `aws-sdk-secretsmanager`
optional deps. Default features remain empty.
- New `auth::aws::SecretsManagerTokenSource` implements `TokenSource` by
fetching a JSON `{"actor_id": "token", ...}` payload from a named
Secrets Manager secret. Credentials resolve via the AWS default chain
(env, shared config, IMDSv2 instance role, ECS task role) so no
explicit plumbing is needed under an IAM role.
- New `resolve_token_source()` dispatches based on the
`OMNIGRAPH_SERVER_BEARER_TOKENS_AWS_SECRET` env var. If the var is set
but the binary was built without `--features aws`, returns a clear
rebuild instruction rather than silently falling back.
- `serve()` now uses `resolve_token_source()` and logs which source was
selected at startup.
- `parse_json_secret_payload()` is factored out as a free function so
the payload validation (trim whitespace, reject blank actor/token,
reject non-object) is unit-testable without the AWS SDK.
- New CI job `test_aws_feature` builds + tests with `--features aws`.
Not in this PR (follow-ups):
- Background refresh loop for rotation. `SecretsManagerTokenSource`
advertises `supports_refresh: true` but the AppState-level refresh
task isn't wired yet.
- Config-YAML dispatch (today the AWS source is selected via env var
only; eventually `server.bearer_tokens.source` in `omnigraph.yaml`).
Tests:
- Default-feature build: 33 lib + 41 integration + 64 openapi.
- `--features aws` build: 32 lib (one test is cfg-gated) + 41 + 64.

Pure refactor. No behavior change. Introduces a TokenSource trait so
additional backends (AWS Secrets Manager, Vault, etc.) can plug in
behind feature flags without touching the server wiring.
- New module crates/omnigraph-server/src/auth.rs with the TokenSource
trait and a single EnvOrFileTokenSource implementation that delegates
to the existing server_bearer_tokens_from_env() function.
- serve() now constructs EnvOrFileTokenSource and calls load() instead
of calling the free function directly.
- The trait has a supports_refresh() hook (false for env/file) for
future implementations that can rotate without restart.
- async-trait added to omnigraph-server deps; it's already in the
workspace.
Tests:
- Unit tests in auth.rs covering load paths and the default supports_refresh
/ name values.
- Existing 128 tests (lib + integration + openapi) pass unchanged.

Fixes two live authz bugs in omnigraph-server:
- Bearer-token lookup previously used HashMap::get, which compares keys with
Eq and short-circuits on the first differing byte — a network-observable
timing oracle for brute-forcing tokens. Tokens are now stored as SHA-256
digests and compared with subtle::ConstantTimeEq, iterating every entry
unconditionally so total work is independent of which slot matches. Raw
token bytes no longer live in server memory after startup.
- authorize_request now overwrites PolicyRequest.actor_id from the
authenticated session instead of trusting the handler-supplied field,
which previously defaulted to "" via unwrap_or_default(). The empty
string can no longer reach Cedar as a policy subject even if a future
refactor drops the None check.
External API of AppState constructors is unchanged — tokens still enter as
Vec<(String, String)> and are hashed on the way in.

Integrate utoipa 5 to auto-generate an OpenAPI 3.1 spec from the existing
Axum handlers and serde types. All 16 endpoints are annotated with path
metadata, request/response schemas, security requirements, and tags. A
public /openapi.json endpoint serves the spec without requiring auth.
Includes 59 tests covering path completeness, HTTP methods, schema fields,
enum variants, security scheme, path/query parameters, request bodies,
response references, and endpoint integration.
