[#3597](https://github.com/a2ui-project/a2ui/issues/3597) - Universal elements rendered from a `ComponentNode` read their props from the node instead of allocating a second `GenericBinder`, and `A2uiLitElement.renderNode` accepts a resolved `ComponentNode` as well as an `A2uiChildRef`. [#3705](https://github.com/a2ui-project/a2ui/pull/3705) - (v1_0) `Catalog.invoker` reads a `ValidationResult` object that a function argument resolves to by its `valid` boolean wherever the function's schema types that argument as `DynamicBoolean`, as the specification defines the type. This applies to every `DynamicBoolean` argument, in built-in and custom catalogs, so `formatNumber`'s `grouping` and a custom function's boolean parameters now read a failing validation as `false` rather than as a truthy object; `and`, `or` and `not` already did. Catalogs below v1.0, whose validation functions return booleans, are unchanged. [#3653](https://github.com/a2ui-project/a2ui/pull/3653) +- Add `mapErrorToRendererMessage` and `extractEnvelopeErrorContext` (along with `ErrorMessage`, `A2uiRendererError`, `ValidationFailedErrorBody`, `GenericErrorBody`, and `ErrorEnvelopeContext`) to `@a2ui/web_core` and `@a2ui/web_core/v0_9`, add `SurfaceGroupModel.onError` and `MessageProcessor.processMessagesWithErrors` for structured outbound renderer error envelopes, and emit RFC 6901 JSON Pointer `path` values on `UNALLOWED_PARENT` and `UNALLOWED_CHILD` composition constraint errors. - v1.0 function RPC payloads name the function with `'@call'`. `RpcHandler.callAgentFunction` rewrites a v0.9-style `call` key to `'@call'` in the outbound `callAgentFunction` message, and `MessageProcessor` passes `'@call'` in the `callRendererFunction` message it hands to the `RpcHandler` ([#3486](https://github.com/a2ui-project/a2ui/issues/3486)). - **BREAKING CHANGE**: Remove cross-catalog `$ref` resolution across peer catalogs, added in 0.14.0. `Catalog.peerCatalogs`, `Catalog.withPeerCatalogs`, the optional `peerCatalogs` and `withPeerCatalogs` members of `CatalogInterface`, `linkCatalogs` and `inlinePeerAndLocalRefs` are removed, and `MessageProcessor` uses the catalogs passed to it as is. A catalog's `$ref`s resolve only against its own document and `common_types.json`, and `Catalog.fromJson` of a v1.0 catalog throws `A2uiCatalogError` (`Unsupported external $ref ...`) for a `$ref` to any other document, such as another catalog, without fetching it; v0.9 catalogs load as before. Recommended migration: copy the referenced definitions into each catalog that uses them. [#3232](https://github.com/a2ui-project/a2ui/issues/3232), [#3575](https://github.com/a2ui-project/a2ui/pull/3575) - Function calls now await pending Promises in their arguments before validating and running, while synchronous calls remain synchronous.

(1) `from_json` cases load a catalog with `Catalog.fromJson`, from an inline `catalog` or a repository-relative `catalogPath`, and check `expect` (`FromJsonExpect` in `conformance_schema.json`). `components` and `functions` list exactly the entries the loaded catalog defines, so a case can check that entries the `anyComponent` and `anyFunction` unions leave out are not loaded. The basic cases set `matchesBuiltinCatalog: true`: the published basic catalog loaded from JSON must be equivalent to the SDK's own basic catalog implementation (same id, version, component and function names, per-component property and required names, and per-function return type, callers and activation). Custom cases cover parsing rules and identifiers. `selfContained: true` requires every `$ref` in the resolved catalog schema to be a local reference that resolves within that document, and `validComponents` / `invalidComponents` list instances that must pass or fail validation. Every published catalog under `specification//catalogs/` and `catalogs///` has a `selfContained` case, and the Python suite fails if one is missing. (2) `to_json` cases compare the whole unbundled document `toJson()` returns with `expectFile`. Each case sets `builtinCatalog: basic` to serialize the SDK's own basic catalog for the case's protocol version and expects the published catalog file. (3) `round_trip` cases load `catalog` or `catalogPath` with `fromJson` (never the SDK's own implementation) and require `toJson()` to equal the input and `fromJson(out).toJson()` to equal `out`. (4) `validation_schema` cases load a published basic catalog, or a small inline catalog that exercises flattening, with `fromJson` and compare `validationSchema`, the successor of `catalogSchema`, with a golden artifact named by `expectFile` under `test_data/validation_schema/`. The goldens use the flattened shape: `allOf` envelopes are flattened, each component gets the `id` envelope, and the common types it references are inlined into `$defs`. An SDK whose output has a different shape lists the case as a known divergence. (5) `derive` cases (`DeriveTest`) load `catalog` or `catalogPath` with `fromJson`, derive a catalog from it with `args`, and check `expect` (`DeriveExpect`): the derived catalog's ID, protocol version, entries, theme and instructions, and the top-level keys its `toJson()` document leaves out. In `args.components` and `args.functions`, a name keeps the source's entry and a map with one key is a new entry. A harness fails a case whose `expect` block uses a key its definition does not list. All comparisons ignore object key order and the order of `enum` and `required` values. - `core/common_types.yaml`: Compares the common types schema that an SDK generates from its own models (`action: common_types_schema`) with the published `specification//json/common_types.json`. Both documents are compared as canonical JSON with sorted keys and must be identical. It also checks the rules those types enforce (`action: validate_common_type`): each step's `value` is validated as the named `definition` with the SDK's own model. A step with `expectError` must be rejected, and any other step must be accepted and serialize back to the same JSON. - `core/agent_to_renderer.yaml`: Compares the `agent_to_renderer` (`server_to_client`) message schema that an SDK generates from its own models (`action: agent_to_renderer_schema`) with the published `specification//json/server_to_client.json` or `specification//json/agent_to_renderer.json`. Both documents are compared as canonical JSON with sorted keys and must be identical. -- `core/accessibility.yaml`: Contains test cases for accessibility attributes and checks. +- `core/accessibility.yaml`: Covers 6 v1.0 accessibility attribute and data binding cases (`action: accessibility_check`). Each case checks static and data-bound `label`, `description`, `live`, and `hidden` attributes across Core SDKs and UI renderers. +- `core/adapter_conformance.yaml`: Covers 13 v1.0 UI framework adapter cases (`action: render_surface`). Each case steps through message processing, data updates, user interactions, and surface disposal. It checks rendered view hierarchies, accessibility attributes, validation states, and outbound actions across `@a2ui/lit`, `@a2ui/react`, `@a2ui/angular`, `a2ui_flutter`, and `A2UISwiftUI`. +- `core/error_responses.yaml`: Covers 24 renderer-to-agent `error` and `rendererFunctionResponse.error` cases across v0.9 and v1.0 (`action: validate`). Each case checks the error category, JSON Pointer `path`, `surfaceId`, and serialized `expectError.rendererError` payload. It compares outbound payloads against `client_to_server.json` (v0.9) and `renderer_to_agent.json` (v1.0). - `core/validator_v0_8.yaml`, `core/validator_v0_9.yaml`, `core/validator_v1_0.yaml`: Contain test cases for schema and structural validation, one suite per protocol version. They cover envelope and component schema checks, duplicate IDs, missing roots, dangling references, cycles, reachability (including list templates and custom v0.8 roots), nesting depth limits, invalid paths, multiple surfaces, and incremental updates. Every case uses `action: validate` in strict mode. The messages in a step are processed in order, so a later message is checked against the components that earlier messages in the same step created. These three suites replace the former `core/validator.yaml`. - `core/data_model.yaml`: Contains test cases for the reactive data model, verifying JSON Pointer reads and writes, container creation, deletion, and observer notification. - `core/message_processor_v0_8.yaml`, `core/message_processor_v0_9.yaml`, `core/message_processor_v1_0.yaml`: Contain test cases for the message processor's state machine, one suite per protocol version. A step of a `process_messages` case may set `validationConfig`, the validation rules for that call only (`ExecutionContext.validationConfig`), in place of the rules the processor was created with. A rule the step leaves out is strict. -- `core/node_resolution.yaml`: Contains node-tree, scoped-binding, notification, identity, action, and destruction scenarios. See [the case format](core/node_resolution.md). +- `core/node_resolution.yaml`: Covers 16 reactive `NodeResolver` and `ComponentNode` cases (`action: resolve_nodes`) executed across TypeScript (`@a2ui/web_core`), Python (`a2ui_core`), Dart (`a2ui_core`), and Swift (`A2UICore`). Scenarios check node tree materialization, scoped template bindings, incremental message streams (`op: process_messages`), cycle and orphan recovery, rule evaluation, action dispatch, and disposal. See [the case format](core/node_resolution.md). - `core/expressions.yaml`: Contains test cases for the client-side expression parser behind `formatString`, covering literals, data bindings, function calls, nested interpolation, escaped markers and parse errors. - `core/functions.yaml`: Contains test cases for the basic catalog functions, and for the catalog a function call runs in on a surface. See [Writing cases for `evaluate_function`](#writing-cases-for-evaluate_function). - `core/message_processor_scaling.yaml`: Timing cases for `processMessages`, with a validation config and without one, which check that a surface arriving in many small messages takes time in proportion to its size.

A step of a `process_messages` case may set `validationConfig`, the validation rules for that call only (`ExecutionContext.validationConfig`), in place of the rules the processor was created with. A rule the step leaves out is strict. These steps belong to the optional `agent_renderer_app` feature (`blueprints/features/agent_renderer_app.blueprint.md`), and an SDK that does not implement it skips their cases. diff --git a/conformance/conformance_harness_implementation_guide.md b/conformance/conformance_harness_implementation_guide.md index c4c63f36b9..2653adfb82 100644 --- a/conformance/conformance_harness_implementation_guide.md +++ b/conformance/conformance_harness_implementation_guide.md @@ -2,11 +2,11 @@ This guide explains how to build conformance test harnesses for an A2UI SDK on a new platform.

Case `test_accessibility_dynamic_label_and_hidden_binding` omits a data model and writes `"@path"` bindings (`{"@path": "/buttonLabel"}`) while asserting normalized `{path: "/buttonLabel"}` binding objects in `accessibilityTree`; when an expected field is a `{path}` map, check the component's unresolved binding descriptor before data resolution. -2. `axeCore`: a list of axe-core rule IDs (`button-name`, `aria-valid-attr-value`, `aria-allowed-attr`, `aria-hidden-focus`) that the rendered DOM must pass.

For example, [typescript/renderers/angular/karma.conf.js](../typescript/renderers/angular/karma.conf.js) parses `accessibility.yaml`, `adapter_conformance.yaml`, and `catalogs/basic/v1/catalog.json` in Node and exposes them to Jasmine browser specs via `client.conformanceSuites`. ## Reference harnesses Inspect these existing implementations for concrete code examples: 1.

[#3705](https://github.com/a2ui-project/a2ui/pull/3705) - (v1_0) `Catalog.invoker` reads a `ValidationResult` object that a function argument resolves to by its `valid` boolean wherever the function's schema types that argument as `DynamicBoolean`, as the specification defines the type. This applies to every `DynamicBoolean` argument, in built-in and custom catalogs, so `formatNumber`'s `grouping` and a custom function's boolean parameters now read a failing validation as `false` rather than as a truthy object; `and`, `or` and `not` already did. Catalogs below v1.0, whose validation functions return booleans, are unchanged. [#3653](https://github.com/a2ui-project/a2ui/pull/3653) - Add `mapErrorToRendererMessage`, `extractEnvelopeErrorContext`, and `normalizeJsonPointer` (along with `RendererErrorMessage`, `A2uiRendererError`, `ValidationFailedErrorBody`, `GenericErrorBody`, and `ErrorEnvelopeContext`) to `@a2ui/web_core`, `@a2ui/web_core/v0_9`, `@a2ui/web_core/v1_0`, and `@a2ui/web_core/processing`, add `SurfaceGroupModel.onError`, `MessageProcessor.processMessagesWithErrors`, `MessageProcessorOptions.errorHandler`, and `MessageProcessorOptions.reportErrorsOnly` for structured outbound renderer error envelopes, add `A2uiErrorDetail`, `A2uiErrorContext`, and `A2uiError` context properties `path`/`surfaceId`/`functionCallId`, and emit RFC 6901 JSON Pointer `path` values on `UNALLOWED_PARENT` and `UNALLOWED_CHILD` composition constraint errors. [#3579](https://github.com/a2ui-project/a2ui/pull/3579) +- (v1_0) Support `@`-prefixed system function calls (such as `${@index()}`) in `ExpressionParser` string interpolation templates. [#3583](https://github.com/a2ui-project/a2ui/pull/3583) - v1.0 function RPC payloads name the function with `'@call'`. `RpcHandler.callAgentFunction` rewrites a v0.9-style `call` key to `'@call'` in the outbound `callAgentFunction` message, and `MessageProcessor` passes `'@call'` in the `callRendererFunction` message it hands to the `RpcHandler` ([#3486](https://github.com/a2ui-project/a2ui/issues/3486)). - **BREAKING CHANGE**: Remove cross-catalog `$ref` resolution across peer catalogs, added in 0.14.0. `Catalog.peerCatalogs`, `Catalog.withPeerCatalogs`, the optional `peerCatalogs` and `withPeerCatalogs` members of `CatalogInterface`, `linkCatalogs` and `inlinePeerAndLocalRefs` are removed, and `MessageProcessor` uses the catalogs passed to it as is. A catalog's `$ref`s resolve only against its own document and `common_types.json`, and `Catalog.fromJson` of a v1.0 catalog throws `A2uiCatalogError` (`Unsupported external $ref ...`) for a `$ref` to any other document, such as another catalog, without fetching it; v0.9 catalogs load as before. Recommended migration: copy the referenced definitions into each catalog that uses them.

[#3705](https://github.com/a2ui-project/a2ui/pull/3705) - (v1_0) `Catalog.invoker` reads a `ValidationResult` object that a function argument resolves to by its `valid` boolean wherever the function's schema types that argument as `DynamicBoolean`, as the specification defines the type. This applies to every `DynamicBoolean` argument, in built-in and custom catalogs, so `formatNumber`'s `grouping` and a custom function's boolean parameters now read a failing validation as `false` rather than as a truthy object; `and`, `or` and `not` already did. Catalogs below v1.0, whose validation functions return booleans, are unchanged. [#3653](https://github.com/a2ui-project/a2ui/pull/3653) - Add `mapErrorToRendererMessage`, `extractEnvelopeErrorContext`, and `normalizeJsonPointer` (along with `RendererErrorMessage`, `A2uiRendererError`, `ValidationFailedErrorBody`, `GenericErrorBody`, and `ErrorEnvelopeContext`) to `@a2ui/web_core`, `@a2ui/web_core/v0_9`, `@a2ui/web_core/v1_0`, and `@a2ui/web_core/processing`, add `SurfaceGroupModel.onError`, `MessageProcessor.processMessagesWithErrors`, `MessageProcessorOptions.errorHandler`, and `MessageProcessorOptions.reportErrorsOnly` for structured outbound renderer error envelopes, add `A2uiErrorDetail`, `A2uiErrorContext`, and `A2uiError` context properties `path`/`surfaceId`/`functionCallId`, and emit RFC 6901 JSON Pointer `path` values on `UNALLOWED_PARENT` and `UNALLOWED_CHILD` composition constraint errors.

[#3583](https://github.com/a2ui-project/a2ui/pull/3583) - v1.0 function RPC payloads name the function with `'@call'`. `RpcHandler.callAgentFunction` rewrites a v0.9-style `call` key to `'@call'` in the outbound `callAgentFunction` message, and `MessageProcessor` passes `'@call'` in the `callRendererFunction` message it hands to the `RpcHandler` ([#3486](https://github.com/a2ui-project/a2ui/issues/3486)). - **BREAKING CHANGE**: Remove cross-catalog `$ref` resolution across peer catalogs, added in 0.14.0. `Catalog.peerCatalogs`, `Catalog.withPeerCatalogs`, the optional `peerCatalogs` and `withPeerCatalogs` members of `CatalogInterface`, `linkCatalogs` and `inlinePeerAndLocalRefs` are removed, and `MessageProcessor` uses the catalogs passed to it as is. A catalog's `$ref`s resolve only against its own document and `common_types.json`, and `Catalog.fromJson` of a v1.0 catalog throws `A2uiCatalogError` (`Unsupported external $ref ...`) for a `$ref` to any other document, such as another catalog, without fetching it; v0.9 catalogs load as before.
