This aligns the one + remaining non-standard error path with every other gateway error; clients that + parsed ``error.code`` / ``error.details`` for this specific failure must read + ``vendor_code`` / ``parameters`` instead + (`#403 `_) * ``ros2_medkit_msgs/srv/ClearFault`` request gains a ``bool skip_correlation_auto_clear`` field (see the per-entity fault scope entry below for the in-tree motivation). Adding a request field changes the service type hash, so out-of-tree callers that invoke the service directly (for example ``ros2 service call /fault_manager/clear_fault ros2_medkit_msgs/srv/ClearFault ...`` as documented in the ``ros2_medkit_fault_manager`` README) must rebuild against the new ``ros2_medkit_msgs`` to keep talking to ``fault_manager``. The in-tree gateway client and server are updated together (`#395 `_) * Per-entity fault routes are now correctly scoped to the entity's hosted apps. ``GET /api/v1/{entity-path}/faults/{fault_code}``, ``DELETE /api/v1/{entity-path}/faults/{fault_code}``, ``GET /api/v1/{entity-path}/faults``, and ``DELETE /api/v1/{entity-path}/faults`` previously fell back to a prefix match against the entity's ``namespace_path``; when that was empty (host-derived / synthetic components, manifest components without a ``namespace`` field, Areas, Functions, and Apps with a wildcard ``ros_binding.namespace_pattern``) the scope filter was silently disabled and the routes exposed - and on ``DELETE``, cleared - faults reported by apps that belonged to entirely different entities. All four handlers now resolve the addressed entity to its hosted-app FQN set (via the new ``HandlerContext::resolve_entity_source_fqns`` helper) and apply a strict all-sources scope check: a fault counts as in scope only when **every** entry in its ``reporting_sources`` is owned by the entity (exact FQN match, or strict path-child via ``/...``). Per-fault routes return ``404 Resource Not Found`` for any fault that fails the check; collection routes return an empty ``items`` array. The underlying ``GetFault.srv`` contract is unchanged; ``ClearFault.srv`` gains a new ``skip_correlation_auto_clear`` request flag so per-entity DELETE can opt out of cascade-clearing correlated symptom fault codes that may live in other entities. Per-entity collection responses no longer include the global ``muted_count`` / ``cluster_count`` / ``muted_faults`` / ``clusters`` correlation metadata; those remain on the global ``GET /api/v1/faults`` route. Behavior changes visible to clients: (a) faults reported by apps outside the addressed entity are no longer returned or cleared via that entity's route, (b) **mixed-source** faults that include at least one out-of-entity reporter are likewise rejected with ``404`` on per-fault routes and excluded from per-entity collection responses (use the global ``GET /api/v1/faults`` to see them), (c) per-entity DELETE no longer cascade-clears correlated symptoms outside the entity (`#395 `_) * ``GET /api/v1/updates/{id}/status`` no longer returns ``404`` for a registered-but-idle package; ``POST /api/v1/updates`` now seeds a ``pending`` status, so the endpoint returns ``200 {"status": "pending"}`` immediately after registration. ``404`` is reserved for packages that are not registered. Clients that used ``404`` as a signal for "registered but nothing started yet" must adapt (`#378 `_) **Features:** +* Typed ``fan_out_collection`` aggregating helper replaces raw-JSON ``merge_peer_items`` on the typed collection routes (data, operations, config, logs). Peer items are decoded via ``dto::JsonReader``; items that fail validation are removed from the merged ``items`` array, recorded in ``x-medkit.peer_dropped_items`` with the JsonReader error plus a best-effort ``source_id``, and logged at ``WARN``. Items that parse successfully are re-serialized through the local ``dto::JsonWriter``, so any peer-supplied fields outside the local DTO schema are dropped from the merged response (the previous raw passthrough preserved unknown peer fields verbatim). Previously, malformed peer items silently disappeared into the merged response; fleet operators can now detect inter-gateway schema drift directly on the wire (`#403 `_) +* ``Collection`` is now a 2-parameter template. Domain list endpoints (faults, config, data, logs) reference their richer per-domain collection x-medkit struct (``FaultListXMedkit``, ``ConfigListXMedkit``, ``DataListXMedkit``, ``LogListXMedkit``) directly in the published schema instead of the generic ``XMedkitCollection``, so generated clients see aggregation counts, peer provenance, and ``peer_dropped_items`` from the schema (`#403 `_) +* New ``opaque_object("key", &T::field)`` DTO field descriptor in ``dto/contract.hpp``. Binds a ``nlohmann::json`` member as a typed "any JSON object" field: ``JsonWriter`` emits it verbatim, ``JsonReader`` rejects scalars / arrays / null, ``SchemaWriter`` emits ``{type: object, additionalProperties: true, x-medkit-opaque: true}``. Used for fields whose runtime shape is decided by an upstream component the gateway cannot introspect (live ROS message payloads, plugin-defined fault envelopes, action results) (`#403 `_) * ``GET /api/v1/faults/stream`` event payloads now carry an optional ``x-medkit`` SOVD payload-extension object with ``entity_type`` and ``entity_id`` fields. When the gateway can resolve the fault's first reporting source back to a SOVD entity (via the manifest-mode linking index, or a runtime-mode last-segment match against an existing App), consumers can hit ``/{entity_type}/{entity_id}/bulk-data/rosbags/{fault_code}`` directly instead of HEAD-probing every entity. Resolution is snapshotted at event arrival, so a discovery refresh between enqueue and stream-out cannot retroactively change the entity reported to consumers. The ``x-medkit`` object is omitted entirely when no entity can be resolved, so existing SSE consumers ignore the addition (`#380 `_) * Plugin API version bumped to v7. Adds ``PluginContext::notify_entities_changed(EntityChangeScope)`` lifecycle hook for plugins that mutate the entity surface at runtime; default no-op keeps v6 source code compiling unchanged against v7 headers. Binary compatibility is not provided: the plugin loader uses a strict equality check on ``plugin_api_version()``, so out-of-tree plugins must be recompiled (`#376 `_) * New ``discovery.manifest.fragments_dir`` parameter: gateway scans the directory for ``*.yaml`` / ``*.yml`` fragment files on every manifest load / reload and merges apps, components, and functions on top of the base manifest. Fragments are forbidden from declaring top-level ``areas``, ``metadata``, ``discovery``, ``scripts``, ``capabilities``, or ``lock_overrides`` - those stay in the base manifest. Presence of any forbidden key (including empty-valued ones like ``areas: []``) is reported as a ``FRAGMENT_FORBIDDEN_FIELD`` validation error that fails the load / reload. Unknown top-level keys (typos such as ``app:`` vs ``apps:``) are ignored with a warning log.

A field added to the +handler body had to be separately added to the schema factory and, if it +appeared in the ``x-medkit`` block, also to the fluent builder. Because the +compiler had no way to enforce the relationship, schemas and wire payloads +drifted silently. The OpenAPI spec served at ``/api/v1/docs`` described a +different shape than what the endpoint actually returned. + +The DTO contract layer resolves this by making the C++ struct the single +source of truth.

The +registry calls ``RouteEntry::response(200, "")`` / +``RouteEntry::request_body("")`` so the wire JSON and the published +schema cannot drift: the same C++ type names both. Hand-attached +``.response(...)`` / ``.request_body(...)`` calls are reserved for non-200 +status documentation (404 / 409 / ...) and for the rare body-less typed +``post`` / ``put`` overloads that parse non-JSON bodies (form-urlencoded +auth) and need an explicit OpenAPI ``request_body`` annotation. + +Escape Hatches +-------------- + +Not every payload can be expressed as a typed DTO. Two orthogonal categories +of escape hatches exist: in-body dynamic payloads (``opaque_object`` fields +inside a DTO, see below) and dedicated non-DTO route helpers. + +Named Route Escape Hatches +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The typed ``RouteRegistry`` exposes a closed set of named escape hatches for +routes whose wire shape is not JSON-and-only-JSON. Each helper produces a +typed handler with a purpose-built response type, so even non-DTO routes +remain compile-time-checked at their boundary. + +- ``reg.sse(path, factory)`` - registers a Server-Sent Events route. The + factory returns a ``Result`` whose ``next_event`` + callback the framework drives via cpp-httplib's chunked content provider. + Used by the fault SSE stream and by cyclic-subscription event streams. +- ``reg.binary_download(path, handler)`` - registers a range-aware binary + download. The handler returns a ``Result`` carrying + ``provider``, ``content_type``, ``filename``, ``supports_ranges``, and + ``total_size``; the framework wires ``provider`` into cpp-httplib's + range-aware content-provider machinery so partial-content fetches work + without manual ``Content-Range`` plumbing. +- ``reg.multipart_upload(path, handler)`` - registers a + ``multipart/form-data`` upload. The handler receives ``http::MultipartBody`` + (already parsed by cpp-httplib) and returns + ``Result>`` so it can pin + 201 + ``Location`` on successful uploads. Used by bulk-data POST/PUT. +- ``reg.static_asset(path, handler)`` - serves bytes already in memory + (Swagger UI bundles, embedded HTML/JS/CSS) as + ``Result`` carrying ``bytes``, ``content_type``, and + per-response ``headers`` (``Cache-Control``, ``ETag``). +- ``reg.docs_endpoint(path, handler)`` - registers the OpenAPI JSON endpoint + at the given path. The handler returns ``Result``; this is + the only built-in route allowed to use raw ``nlohmann::json`` as + ``TResponse``, because the body is the spec itself. +- ``reg.docs_subtree(regex, handler)`` - catch-all for the Swagger UI subtree + (asset paths without a fixed shape). Hidden from the OpenAPI output so it + does not pollute the generated spec. +- ``reg.post_alternates(path, handler)`` / + ``reg.del_alternates(path, handler)`` - register multi-shape + responses. The active variant alternative is dispatched to its + ``dto_alternate_status::value`` (default 200; specialize per type, for + example ``Accepted`` -> 202, ``NoContent`` -> 204). The published spec + lists every alternative under its own status code, and the wire status is + picked by the active alternative at call time. + +Plugin-Owned Routes (``PluginContext::register_route()``) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Routes contributed by ``GatewayPlugin`` subclasses bypass the typed router +entirely and run a ``void(PluginRequest, PluginResponse)`` handler that the +plugin owns. ``PluginResponse`` is a thin shim over a cpp-httplib response +whose ``send_json`` / ``send_error`` methods route through the same internal +``http::detail::write_json_body`` primitive used by the typed router, so +plugin responses remain wire-format-identical to built-in responses (same +SOVD ``GenericError`` shape, same ``Content-Type`` handling). The plugin +ABI is locked by ``test_plugin_abi_conformance``; nothing here changes for +out-of-tree plugins. + +Opaque Object Policy +-------------------- + +Some DTO fields carry an entire JSON object whose internal shape is decided +at runtime by an upstream component the gateway cannot introspect at compile +time. The ``opaque_object("key", &T::field)`` descriptor in +``dto/contract.hpp`` binds such a field to a ``nlohmann::json`` member: + +- **JsonWriter** writes the member as-is (no introspection, no schema check). +- **JsonReader** accepts any JSON object value, rejects scalars / arrays / + null with a ``FieldError``; an absent field leaves the member at its + default (empty object). +- **SchemaWriter** emits + ``{type: object, additionalProperties: true, x-medkit-opaque: true}`` and + marks the field required (opaque fields are not wrapped in ``std::optional``). + +Use ``opaque_object`` for fields whose runtime shape depends on context, not +for fields the gateway could describe but chose not to. Concrete cases in +the codebase: + +- **Live ROS 2 message payloads** - topic samples returned by data handlers + carry whatever fields the actual message type declares at runtime. +- **Plugin-defined fault envelopes** - ``FaultListResult`` / + ``FaultDetailResult`` / ``FaultClearResult`` returned by the typed + ``FaultProvider`` ABI wrap a ``content`` opaque object so UDS, OPC-UA, and + vendor backends can each emit their own per-item shape. +- **Action results / service responses** - ``Operation*`` execution + payloads whose field set is determined by the ROS 2 service / action type + bound to the operation, not by the gateway. +- **OpenAPI spec body** - the ``/docs`` endpoint returns the spec itself, + declared via ``reg.docs_endpoint(path, Result(...))`` (a route-level + escape hatch, not an opaque DTO field). + +Fields backed by ``std::optional`` rather than +``opaque_object`` (notably ``extended_data_records`` / ``snapshots`` on +``FaultEnvironmentData``) follow the same rule: pass the JSON through +verbatim because the fault reporter plugin owns the shape. The opaque DTO +marker (``is_opaque_dto_v = true``) plays the analogous role at the +envelope level: it tells the framework "this whole DTO has a hand-written +JsonWriter / JsonReader / SchemaWriter trio because its shape is opaque", +which is what the typed Provider envelopes use. + +Provider ABI: Typed-Only Policy +------------------------------- + +Per-entity provider interfaces (``FaultProvider``, ``DataProvider``, +``OperationProvider``) and the singleton ``UpdateProvider`` all return typed +DTOs. None of them return raw ``tl::expected`` +any more. + +The typed envelopes - ``FaultListResult``, ``FaultDetailResult``, +``FaultClearResult``, the corresponding ``Data*Result`` and ``Operation*Result`` +shapes, and ``UpdateProvider::get_update``'s typed return - wrap an opaque +``content`` payload so the wire bytes are byte-identical to the pre-typed +ABI: ``JsonWriter`` emits the ``content`` object verbatim, ``SchemaWriter`` +publishes ``x-medkit-opaque: true``, and JsonReader accepts any JSON object +on round-trip. This keeps backend-specific shapes (UDS DTC records, OPC-UA +alarm metadata, vendor extensions) flowing through unchanged while pinning +the envelope itself to a single typed contract. + +Commercial plugins (UDS, OPC-UA, Uptane OTA, ...) implement the typed +interface directly. Out-of-tree plugins that previously returned raw +``nlohmann::json`` must wrap their response in the matching envelope type; +the conversion is mechanical (``Result.content = std::move(json_payload)``). + +Fan-Out Observability +--------------------- + +Aggregating collection routes call ``http::fan_out_collection(agg, req)`` +to query peer gateways and merge their ``items`` arrays. The helper returns +a typed ``FanOutResult``: + +.. code-block:: cpp + + template + struct FanOutResult { + std::vector items; // parsed peer items + bool partial{false}; // at least one peer failed + std::vector failed_peers; + std::vector dropped_items; // items that failed JsonReader + }; + +Each peer item is decoded via ``dto::JsonReader``. Items that fail +validation are removed from ``items`` and recorded in ``dropped_items`` with +the JsonReader error message plus a best-effort ``source_id`` extracted from +the item's ``id`` / ``name`` / ``fault_id`` / ``data_id`` / ``operation_id`` +field. A ``WARN`` log fires for each drop, naming ``dto_name`` and the +reason. The peer URL on each ``DroppedItem`` is left empty in this commit +because ``AggregationManager::fan_out_get`` coalesces all peer responses +into a single merged array without per-item provenance; per-peer attribution +is left for a future enrichment of the aggregation manager. + +Handlers surface drops on the wire via the ``peer_dropped_items`` field on +every collection-level x-medkit DTO (``XMedkitCollection``, +``FaultListXMedkit``, ``FaultListAggXMedkit``, ``DataListXMedkit``, +``LogListXMedkit``, ...). Previously, malformed peer items disappeared +silently into the merged ``items`` array; now they show up in +``x-medkit.peer_dropped_items`` so clients (and fleet operators) can detect +drift between heterogeneous gateways. The legacy ``merge_peer_items`` helper +(raw-JSON mutation) is still in use on routes whose merged items are +dynamic-shaped (the fault aggregation routes, ``GET /health``), where the +items are not addressable by a single ``T`` for ``JsonReader``; typed +collection routes (data, operations, config, logs) call +``fan_out_collection`` directly. + +OpenAPI Generation Pipeline +--------------------------- + +The published ``openapi.json`` is assembled mechanically from two sources: + +- ``components/schemas`` is the union of + ``collect_component_schemas()`` (one entry per DTO listed in + ``dto/registry.hpp``) and a small set of explicit survivors in + ``SchemaBuilder::component_schemas()`` for genuinely dynamic ROS payloads + (``from_ros_msg`` / ``from_ros_srv_request`` / ``from_ros_srv_response``, + ``binary_schema``, ``generic_object_schema``). +- ``paths`` is ``RouteRegistry::to_openapi_paths()``: every typed route + contributes a path item with ``$ref`` entries auto-derived from its + ``TResponse`` / ``TBody`` template parameters plus any tags, summary, + description, ``operation_id``, parameter, or extra-status metadata pinned + on the route via the fluent ``RouteEntry`` builder. + +``OpenApiSpecBuilder::build()`` then assembles ``info`` / ``servers`` / +``tags`` / ``security`` around those two compiled blocks. There are no +hand-written ``paths`` items in the published spec, and no hand-written +schema blocks beyond the survivors above. Adding a route or a DTO field +updates the spec on the next process start with no schema-side edit. + +Optional fields are now emitted as ``anyOf: [, {type: "null"}]`` +(OpenAPI 3.1 idiom) so generated clients see ``T | null`` rather than +``T | undefined``. That matches the wire reality of the gateway: optional +fields are either present-with-value or absent, never explicit ``null``; +but the schema also accepts ``null`` so clients that prefer to emit a +nullable value on the wire round-trip cleanly through ``JsonReader``. + +Adding a New DTO +---------------- + +Follow these four steps when introducing a new typed payload: + +1. **Define the struct and its descriptor** in the appropriate domain header + under ``include/ros2_medkit_gateway/dto/``. Add a ``dto_fields`` + specialization and a ``dto_name`` specialization in the same header. + + .. code-block:: cpp + + // In dto/my_domain.hpp + struct MyResponse { + std::string id; + std::optional label; + int64_t count{0}; + }; + + template <> + inline constexpr auto dto_fields = std::make_tuple( + field("id", &MyResponse::id), + field("label", &MyResponse::label), + field("count", &MyResponse::count)); + + template <> + inline constexpr std::string_view dto_name = "MyResponse"; + +2. **Register in AllDtos** by adding ``MyResponse`` to the tuple in + ``include/ros2_medkit_gateway/dto/registry.hpp``. Also add the include + for ``dto/my_domain.hpp`` at the top of ``registry.hpp``. + +3. **Use in the handler.** Handlers never touch ``httplib::Response`` - they + return ``http::Result`` and the framework writes the body. + Entity validation is also typed: ``validate_entity_for_route`` returns + ``http::ValidatorResult``; the helper ``flatten_validator_error`` + collapses the local-error and ``Forwarded`` branches into a single + ``ErrorInfo`` (the ``Forwarded`` branch becomes the framework-internal + sentinel that the RouteRegistry wrapper recognises and skips error + rendering for): + + .. code-block:: cpp + + // GET handler - typed response + http::Result MyHandlers::handle_get(http::TypedRequest req) { + auto entity = ctx_.validate_entity_for_route(req, req.path_param(0)); + if (!entity) { + return tl::make_unexpected(flatten_validator_error(entity.error())); + } + + dto::MyResponse resp; + resp.id = entity->id; + resp.label = "example"; + resp.count = 42; + return resp; + } + + // POST handler - typed request body (parsed by the framework before + // the handler runs; the handler receives an already-validated TBody). + http::Result MyHandlers::handle_post( + http::TypedRequest req, dto::MyCreateRequest body) { + // use body.field_name directly + dto::MyResponse resp; + // ... build response ... + return resp; + } + +4. **Register the route via the typed RouteRegistry.** Because ``MyResponse`` + is now in ``AllDtos``, ``collect_component_schemas()`` automatically + includes its schema in the ``/docs`` response, and the typed overload + wires the ``$ref`` into the path item: + + - For **built-in gateway routes**, register in + ``rest_server.cpp::setup_routes()`` via ``reg.get`` / + ``reg.post`` / etc. The framework derives the + ``response(200, "")`` and ``request_body("")`` slots from the + template parameters; the call site only adds tags, summary, extra + status codes, and ``operation_id``: + + .. code-block:: cpp + + reg.get( + "/my-entity/{id}/my-resource", + [this](http::TypedRequest req) -> http::Result { + /* handler */ + }) + .tag("MyTag") + .summary("Get my resource") + .operation_id("getMyResource") + .response(404, "Resource not found"); // extra non-200 status + + - For **plugin-contributed routes**, use the ``RouteDescriptionBuilder`` + API in ``core/openapi/route_descriptions.hpp``. Plugin routes do not go + through the typed registry (see Plugin-Owned Routes above), so the + schema wire-up is explicit. + +Adding a New Endpoint (Full Checklist) +-------------------------------------- + +A new endpoint with a typed payload follows the standard gateway handler +checklist plus the DTO steps above: + +1. Define DTO struct + ``dto_fields`` + ``dto_name`` in a domain header. +2. Add to ``AllDtos`` in ``registry.hpp``. +3. Implement handler in ``src/http/handlers/`` as a typed function returning + ``http::Result``. +4. Register route in ``rest_server.cpp::setup_routes()`` via + ``reg.get`` / ``reg.post`` / ``reg.del`` / the matching + alternates or escape-hatch helper. Use the dual-path pattern for entity + types that share the same route shape. +5. Update ``handle_root`` endpoint list in ``health_handlers.cpp`` to mirror + the new route. +6. Add URI field to entity detail response if the new route is a resource + collection. +7. Write a unit test using ``JsonWriter::write()`` and + ``JsonReader::read()`` directly - no HTTP server needed. +8. Write an integration test that calls the live endpoint. + +Collection Parametrisation +--------------------------------------- + +The generic ``Collection`` list wrapper is parameterised over +both the item type and the collection-level ``x-medkit`` shape. Entity list +endpoints (areas, components, apps, functions) use the default +``XMedkitCollection`` x-medkit; the domain collection endpoints specialise +``XMedkitT`` to their richer per-domain shape (``FaultListXMedkit``, +``FaultListAggXMedkit``, ``ConfigListXMedkit``, ``DataListXMedkit``, +``LogListXMedkit``), so the published schema for each list response now +references the actual collection x-medkit struct.
