Migration to @objectstack/spec as Protocol Constitution

✅ Implementation Complete

This PR successfully migrates @objectql/types to use @objectstack/spec (v0.1.1) as the single source of truth for all metadata/AST interfaces.

Implementation Checklist

Changes Summary

Phase 1: Core Type Integration

Added @objectstack/spec dependency to packages/foundation/types/package.json
Refactored field.ts:
- Imports Field, FieldType and SelectOption from spec
- Extends with runtime types (vector, grid, location, object)
- Extends with runtime properties (file upload constraints, AI context, validation)
- Makes boolean flags optional (required, multiple, unique, etc.) for runtime convenience
Refactored object.ts:
- Imports ServiceObject and IndexSchema from spec
- Extends with runtime properties (AI config, actions, validation)
Refactored action.ts:
- Imports Action from spec
- Extends with runtime execution context and handler functions

Phase 2: Protocol Alignment

Fixed field naming to match protocol:
- auto_number → autonumber (aligned with spec)
- min_length / max_length → minLength / maxLength (aligned with spec camelCase)
Updated core utilities (util.ts):
- Added required name field to generated FieldConfig objects
- Changed max_length to maxLength
Updated runtime server:
- Fixed GraphQL adapter to use autonumber
- Fixed metadata endpoint to use camelCase field names
Updated CLI tools:
- Fixed code generator to use autonumber
- Fixed sync command to use maxLength
Updated tests:
- Fixed util.test.ts to expect maxLength instead of max_length

Phase 3: PR Review Feedback (Latest)

Improved FieldConfig documentation:
- Added detailed comment explaining why each property is omitted from protocol Field type
- Documented the purpose of re-declaring protocol properties with different optionality
Enhanced deprecated property guidance:
- Added comprehensive migration guide for reference_to → reference migration
- Included YAML examples showing old vs new patterns
Removed ambiguous deprecated properties:
- Removed top-level regex property (deprecated in favor of validation.pattern)
- Removed validation.regex alias to eliminate ambiguity
- Updated validator and metadata endpoint to use only validation.pattern
Clarified name property usage:
- Added comments explaining when name must be set explicitly (programmatic creation)
- Distinguished from YAML usage where name is auto-populated from Record key

Key Principles Applied

✅ Zero Duplication: Removed all types that exist in @objectstack/spec
✅ Extension Only: Only added properties specific to runtime that don't belong in wire protocol
✅ Strict Typing: Maintained strict TypeScript typing throughout
✅ Protocol First: Aligned all naming with the Protocol Constitution
✅ Backwards Compatibility: Runtime extensions maintain backward compatibility
✅ Clear Migration Paths: Provided explicit guidance for deprecated properties

Test Results

✅ 236 tests passing
✅ 0 failures
✅ All packages build successfully
✅ No TypeScript compilation errors

Architecture Notes

The migration establishes a clean separation:

@objectstack/spec (The Constitution): Defines the wire protocol types
@objectql/types (Runtime Extensions): Imports and extends protocol types with runtime-specific properties
@objectql/core (The Engine): Consumes types from @objectql/types

This architecture ensures:

The protocol remains stable and version-controlled via @objectstack/spec
Runtime features can be added without polluting the protocol
All parts of the monorepo consume types through a single entry point (@objectql/types)

Original prompt

This section details on the original issue you should resolve

<issue_title>[Feature]: The package @objectstack/spec (v0.1.1) is now the "Constitution" for all Metadata/AST interfaces.</issue_title>
<issue_description>### Is your feature request related to a problem? Please describe.

Role: ObjectStack Senior Architect

Mission: Protocol Migration & Type Alignment

We are refactoring the objectql monorepo to strictly adhere to the new upstream protocol definition.
The package @objectstack/spec (v0.1.1) is now the "Constitution" for all Metadata/AST interfaces.

Context

I have installed @objectstack/spec in packages/foundation/core and plan to install it in packages/foundation/types.
Currently, packages/foundation/types contains duplicate manual definitions of what is now in the Spec.

Your Task

Execute the following "Atomic Workflow" to align the codebase:
Analyze the Spec

Check the exports of @objectstack/spec.

Identify which interfaces in packages/foundation/types/src/*.ts overlap with the Spec (e.g., ObjectConfig, FieldConfig, ActionConfig).
Refactor "The Constitution" (@objectql/types)
Modify packages/foundation/types/package.json: Add dependency @objectstack/spec.

Update packages/foundation/types/src/index.ts: Re-export common types from the Spec.
Refactor individual files (e.g., object.ts):
DELETE local interfaces that duplicate the Spec.

EXTEND Spec interfaces if we have runtime-specific properties that are not part of the wire protocol.
Example pattern:
import { ObjectSpecification } from '@objectstack/spec';
// Only add properties that exist in Runtime but NOT in Spec
export interface ObjectConfig extends ObjectSpecification {
    // runtime_cache_key?: string;
}
Update the Engine (@objectql/core)

Ensure core imports strictly from @objectql/types (which now bridges the Spec) or directly from @objectstack/spec only if needed for value objects/constants.

Fix any type errors resulting from the switch (e.g., strict null checks or changed property names).
Constraints

Strict Typing: No any. Use unknown with type guards if necessary.

Zero Duplication: If a type exists in @objectstack/spec, do not redefine it.

Backwards Compatibility: If the Spec explicitly changes a field name, mark the old one as @deprecated in our local type if needed, or update the Core to use the new standard.

Start by listing the files in packages/foundation/types/src that need to be modified based on the standard *.object.yml or *.field.yml patterns.

Pull request overview

This PR migrates the type system to use @objectstack/spec v0.1.1 as the single source of truth for protocol definitions, eliminating duplicate type definitions and establishing a clean separation between protocol (wire format) and runtime (implementation) types.

Changes:

Refactored @objectql/types to import and extend protocol types from @objectstack/spec rather than duplicating definitions
Standardized field type and property naming to match protocol conventions (auto_number → autonumber, max_length → maxLength)
Updated core utilities, GraphQL adapter, metadata endpoints, and CLI tools to use protocol-compliant naming

-    description?: string;

-    /** The data type of the field. */
+export interface FieldConfig extends Omit<Field, 'type' | 'options' | 'required' | 'multiple' | 'unique' | 'deleteBehavior' | 'hidden' | 'readonly' | 'encryption' | 'index' | 'externalId'> {


The Omit list contains 11 properties being excluded from the base Field type. This creates a tight coupling to the protocol definition and makes the interface fragile - any changes to the protocol's Field interface could silently break this contract. Consider using a Pick approach to explicitly declare which protocol properties are inherited, or document why each property needs to be re-declared.

Added detailed documentation explaining each omitted property and why it needs to be re-declared (optionality differences, type extensions). This documents the contract explicitly rather than leaving it implicit. See commit 9f1b180.

    /**
     * Reference to another object for lookup/master_detail fields.
-     * Specifies the target object name for relationship fields.
+     * @deprecated Use 'reference' from SpecField instead


This property is marked as deprecated in favor of the protocol's reference field, but there's no migration path or guidance provided. Consider adding a comment explaining how to migrate from reference_to to reference, or implement a getter/setter that maps between the two to ease the transition.

Suggested change

* @deprecated Use 'reference' from SpecField instead

*

* @deprecated Legacy alias for the protocol-level {@link SpecField.reference} field.

*

* Migration guidance:

* - New schemas MUST use the `reference` field defined on SpecField (wire protocol) instead of `reference_to`.

* - During migration, engines and tooling SHOULD:

* - Treat `reference_to` as a fallback alias for `reference` (i.e., if `reference` is undefined and `reference_to`

* is defined, behave as though `reference` were set to the same value).

* - Prefer the protocol `reference` value when both are present.

*

* This property is retained only for backward compatibility with older *.object.yml definitions and may be removed

* in a future major version once all callers have migrated to `reference`.

Added comprehensive migration guide with YAML examples showing the old (deprecated) pattern vs. the new protocol-compliant pattern. The guide explains the fallback behavior and timeline for removal. See commit 9f1b180.

+     * Regular expression pattern for validation.
+     * @deprecated Use validation.pattern instead
+     */
    regex?: string;


This property is marked as deprecated in favor of validation.pattern, but it's also included again inside the validation object (line 230 has regex as an alias for pattern). This creates ambiguity about which property should be used. Consider removing the deprecated top-level property entirely or providing a clear migration timeline.

Removed both the top-level deprecated regex property and the validation.regex alias to eliminate ambiguity. Now only validation.pattern is supported. Updated validator.ts and metadata.ts accordingly. See commit 9f1b180.

            if (foreignKey) {
                // This is a lookup field
                fieldConfig = {
+                    name: column.name,


The name property is now explicitly set in both lookup and regular field configurations. This is redundant since the comment on line 114 in the original code states 'If defined within an object map, this is often automatically populated from the key.' Consider documenting why explicit name assignment is now required, or if this is needed for protocol compliance.

Added clarifying comments explaining that explicit name assignment is required when creating FieldConfig programmatically (as in database introspection). The auto-population behavior applies only to YAML definitions where the Record key becomes the field name. See commit 9f1b180.

…mpilation errors The @objectstack/spec package requires name and label fields on the Field type, but when fields are defined in ObjectConfig.fields as a Record<string, FieldConfig>, the name is inferred from the record key. This change makes name and label optional in FieldConfig to match this usage pattern. Co-authored-by: huangyiirene <7665279+huangyiirene@users.noreply.github.com>
