PR 6b of the MR-668 multi-graph server work. First management endpoint —
`GET /graphs` lists every graph registered with the server, gated by the
server-level Cedar policy from PR 6a.
New API shapes (in `omnigraph-server::api`):
- `GraphInfo { graph_id, uri }` — one entry per registered graph.
- `GraphListResponse { graphs: Vec<GraphInfo> }` — sorted alphabetically
by `graph_id` for deterministic output.
Handler `server_graphs_list`:
- Mounted at `GET /graphs` in both modes.
- Single mode: returns 405 (resource exists in the API surface, just
not operational without a `graphs:` map). 405 chosen over 404 so
clients see "resource exists, wrong context" rather than "no such
resource".
- Multi mode: requires bearer auth (when configured); Cedar-gated by
`PolicyAction::GraphList` against `Omnigraph::Server::"root"`
(PR 6a's chassis). Returns the sorted registry list.
Cedar gate composition:
- When no `server.policy.file` is configured, the MR-723 default-deny
falls through: `GraphList` is not `Read`, so an authenticated actor
without a server policy gets 403. This is the right default — don't
expose the registry until the operator explicitly authorizes it.
- When a server policy is configured, Cedar evaluates the rule. The
test `get_graphs_with_server_policy_authorizes_per_cedar` pins the
admin-allow / viewer-deny split.
Routing:
- New `management` sub-router holding `/graphs` (auth-required, no
`resolve_graph_handle` middleware — operates on the registry, not
a single graph).
- Single mode merges flat protected routes + management.
- Multi mode merges nested `/graphs/{graph_id}/...` + management.
OpenAPI:
- `server_graphs_list` registered in `ApiDoc::paths(...)`.
- `EXPECTED_PATHS` in `tests/openapi.rs` gains `/graphs`.
- `openapi.json` regenerated (auto-tracked by
`openapi_spec_is_up_to_date` in CI).
Tests: 4 new in `tests/server.rs::multi_graph_startup`:
- `get_graphs_lists_registered_graphs_in_multi_mode`
- `get_graphs_returns_405_in_single_mode`
- `get_graphs_requires_bearer_auth_when_configured`
- `get_graphs_with_server_policy_authorizes_per_cedar`
What's NOT in this PR (deferred):
- Per-graph policy enforcement is wired through `handle.policy`
(PR 4a already did this); PR 6b doesn't add new per-graph
behavior beyond making sure the server policy lookup composes
cleanly alongside it.
- `POST /graphs` (PR 7) and `DELETE /graphs/{id}` (out of scope
for v0.7.0).
- CLI `omnigraph graphs list` (PR 8 will add).
Result: 215 server tests green (74 lib + 66 openapi + 75 integration),
11 policy tests green. MR-731 spoof regression preserved across all
this work.

PR 4b of the MR-668 multi-graph server work. In multi mode, the served
`/openapi.json` reports cluster routes (`/graphs/{graph_id}/...`) instead
of the legacy flat protected paths — matching what `build_app` actually
mounts (PR 4a's `Router::nest`). Single mode is unchanged.
Implementation:
- New `server_openapi` branch: when `state.mode()` is `Multi`, call
`nest_paths_under_cluster_prefix(&mut doc)` after `ApiDoc::openapi()`.
- The rewrite consumes `doc.paths.paths`, then for every path-item:
- If the path is in `ALWAYS_FLAT_PATHS` (`/healthz` for now), keep
it flat.
- Otherwise, prefix every operation_id with `cluster_` and reinsert
the item at `/graphs/{graph_id}<original_path>`.
- Single mode hits no extra work — the path map is untouched.
- The static `ApiDoc::openapi()` still emits the flat surface, so
in-process callers (the existing `openapi_json()` helper in tests)
see the unmodified spec.
Why cluster_ prefix on operation IDs: OpenAPI specs require unique
operation_ids across the document. With both flat (single-mode) and
cluster (multi-mode) surfaces ever co-existing in a generated SDK,
the prefix prevents collision. The current served doc only carries
one surface, so the prefix is forward-compat with potential future
dual-surface generation.
Tests: 6 new in `tests/openapi.rs`, all via the `/openapi.json` route
(not the static `ApiDoc::openapi()` helper):
- `multi_mode_openapi_lists_cluster_paths` — every protected path
appears as a cluster variant.
- `multi_mode_openapi_drops_flat_protected_paths` — flat protected
paths are absent.
- `multi_mode_openapi_keeps_healthz_flat` — `/healthz` survives.
- `multi_mode_openapi_prefixes_operation_ids_with_cluster` — every
cluster operation_id starts with `cluster_`.
- `multi_mode_operation_ids_are_unique` — no operation_id collisions.
- `single_mode_openapi_unchanged_by_cluster_filter` — single mode
still emits the legacy flat surface (regression).
New test helper `app_for_multi_mode(graph_ids)` exercises the new
`AppState::new_multi` constructor from PR 4a — first user of multi-mode
construction outside of unit tests.
Result: 66 openapi tests + 57 server integration tests + 74 lib tests
= 197 green. No regression in the existing OpenAPI drift check
(`openapi_spec_is_up_to_date` still validates the static flat surface
matches the committed openapi.json).
LOC: +67 in lib.rs (rewrite logic), +219 in tests/openapi.rs (test
suite + helper).

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.

The separate openapi-sync workflow was duplicating the workspace build
(~15 min cold-cache compile), paying the cost twice per PR. Fold the
regen + auto-commit into the existing test job: one compile, shared
rust-cache, same drift-check semantics.
- Same-repo PRs: OMNIGRAPH_UPDATE_OPENAPI=1 during the test run, then
commit the regenerated spec back to the PR branch
- Fork PRs / pushes: env var empty, test stays in strict drift-check mode
- openapi_spec_is_up_to_date treats empty env value as unset, so the
conditional workflow env expression works

Introduce SDK generation scaffolding: commit a static openapi.json
extracted from the Utoipa annotations via a golden-file test, add
Stainless workspace/config for TypeScript and Python SDKs, and clean
up operation IDs for ergonomic generated method names.

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.

The served OpenAPI spec now matches runtime behavior: when no bearer
tokens or policy are configured (open mode), the spec omits security
schemes and per-operation security requirements. When auth is active,
the full bearer_token security metadata is included.
Also fixes SecurityAddon to initialize components if absent, and
removes the redundant utoipa dev-dependency.
Adds 5 new tests covering open-mode vs auth-mode spec serving.
https://claude.ai/code/session_01NfoPVx21rZUQned1f7WpXY
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.
