Pull request overview
This PR implements Phase 1 of the ObjectStack Spec v0.7.1 alignment in the types and core layers, focusing on object-level validation, enhanced query capabilities (window functions and aggregations), and a richer UI action schema. It also wires these features into the public exports and adds comprehensive unit tests for the new validation engine and window function AST builder.
Changes:
- Add a new
UIActionSchemaand related types in@object-ui/typesfor location-aware, parameterized, and conditional UI actions. - Extend the data protocol to support window functions, new aggregation functions, join strategies, and a full object-level validation type system.
- Implement an
ObjectValidationEnginein@object-ui/corewith tests, and extend the query AST builder and tests to support window function nodes.

| File | Description |
|---|---|
| packages/types/src/ui-action.ts | Introduces the enhanced UI action type system (locations, components, params, feedback, context) to model ObjectStack v0.7.1 actions. |
| packages/types/src/index.ts | Re-exports new query, validation, and UI action types (including UIActionSchema) to expose them as part of the public types package API. |
| packages/types/src/data-protocol.ts | Extends the query AST with window functions, enhanced aggregations, join strategy hints, and adds a full set of object-level validation interfaces and rule union types. |
| packages/types/src/app.ts | Adds homePageId and requiredPermissions to AppSchema to support app-level navigation defaults and access control. |
| packages/core/src/validation/validators/object-validation-engine.ts | Implements the object-level validation engine for all new validation rule types, including script, uniqueness, state machine, cross-field, async, conditional, format, and range validations. |
| packages/core/src/validation/validators/index.ts | Exposes the object validation engine, default instance, helper, and related types from the validators module. |
| packages/core/src/validation/index.ts | Re-exports the new validators module from the core validation entrypoint to make object-level validation part of the public @object-ui/core/validation API. |
| packages/core/src/validation/tests/object-validation-engine.test.ts | Adds a comprehensive Vitest suite covering behavior of all object-level validation types and engine features (events, active flag, severity). |
| packages/core/src/query/query-ast.ts | Updates the query AST builder to support window function nodes and to type select-field lists as including WindowNode, with a dedicated buildWindow helper. |
| packages/core/src/query/tests/window-functions.test.ts | Adds tests validating that QueryASTBuilder builds correct WindowNode structures for all supported window functions and frame/partition/order configurations. |

The variant union on ActionSchema includes 'primary', but the underlying Button component’s variant cva only supports default | destructive | outline | secondary | ghost | link (see packages/components/src/ui/button.tsx). To avoid runtime mismatches where a primary action variant silently falls back to default styling, the allowed variants here should be kept in sync with the button variants or mapped explicitly in the renderer.

SimpleExpressionEvaluator currently evaluates validation expressions using new Function, which effectively executes arbitrary code from the rule string and bypasses the existing ExpressionEvaluator/evaluateExpression infrastructure in core. To keep object-level validation consistent with the rest of the engine and avoid introducing an RCE-style surface, this default implementation should be replaced with a wrapper around the shared expression engine (or another safe, injected evaluator) rather than constructing functions from raw strings.

The validateAsync implementation ignores the debounce and cache configuration defined on AsyncValidation in @object-ui/types, even though the PR description advertises "remote endpoint + caching" support. If those options are meant to be part of the object-level validation behavior, this method should either implement debouncing and a cache keyed by endpoint/payload or, if they are out of scope here, the type/docs should be adjusted so callers aren’t misled into expecting caching that never occurs.

validateAsync hardcodes a dependency on the global fetch API and assumes a specific JSON response shape ({ valid: boolean; message?: string }), which tightly couples this core validator to a particular runtime and protocol. To keep @object-ui/core environment-agnostic, consider injecting an HTTP client/async validator function (similar to uniquenessChecker) or delegating remote checks to a data adapter layer instead of calling fetch directly and parsing the response here.

There was a problem hiding this comment.
AggregateNode.function includes the new aggregation functions (count_distinct, array_agg, string_agg) and a separator field for string_agg, but the higher-level AggregationConfig type still only allows count | sum | avg | min | max and has no way to specify a separator. As a result, these new aggregations are not expressible from QuerySchema, so it would be better to align AggregationConfig with AggregateNode (including the extended function union and optional separator) or clearly document that these functions are only available when constructing the AST directly.
