Add P0 missing protocols: Notification, Document, Change Management, External Lookup

[Copilot]

Implements 4 critical missing protocols to complete the ObjectStack specification for enterprise features.

Protocols Added

1. Notification Management (system/notification.zod.ts)

• Unified multi-channel delivery (Email, SMS, Push, In-app, Slack, Teams, Webhook)
• Template engine with variable interpolation
• Scheduling modes: immediate, delayed, scheduled
• Retry policies with exponential/linear/fixed backoff
• Delivery tracking (opens, clicks, delivery status)

2. Document Management (data/document.zod.ts)

• Immutable version control with checksum validation
• Template-driven generation with typed placeholders
• E-signature workflows (DocuSign, Adobe Sign, HelloSign, custom)
• Time-based access control with sharing rules

3. Change Management (system/change-management.zod.ts)

• ITIL-compliant request lifecycle (standard, normal, emergency, major)
• Impact assessment with downtime estimation
• CAB approval routing with audit trail
• Mandatory rollback procedures with test validation

4. External Lookup (data/external-lookup.zod.ts)

• Real-time external data queries (OData, REST, GraphQL)
• OAuth2/API Key/Basic authentication
• Multi-strategy caching (LRU, LFU, TTL)
• Rate limiting with burst handling and graceful degradation

Usage Example

import { NotificationConfigSchema, ExternalLookupSchema } from '@objectstack/spec';

// Multi-channel notification with retry
const notification = {
  channel: 'email',
  template: {
    subject: 'Order {{order_id}} shipped',
    body: 'Tracking: {{tracking_number}}',
    variables: ['order_id', 'tracking_number']
  },
  retryPolicy: {
    maxRetries: 3,
    backoffStrategy: 'exponential'
  }
};

// Salesforce-like external data integration
const salesforceLookup = {
  dataSource: {
    type: 'rest-api',
    endpoint: 'https://api.salesforce.com/v58.0',
    authentication: { type: 'oauth2', config: {...} }
  },
  fieldMappings: [
    { externalField: 'AccountName', localField: 'account_name', readonly: true }
  ],
  caching: { ttl: 300, strategy: 'ttl' }
};

Technical Notes

• All schemas are Zod-first with derived TypeScript types
• Naming: camelCase for configuration keys, snake_case for data identifiers
• Generated 19 JSON schemas for runtime validation
• 109 tests added (100% coverage on new code)
• Aligned with Salesforce External Objects, ServiceNow CMDB, ITIL v4

There is a naming collision: FieldMappingSchema is already defined in packages/spec/src/data/mapping.zod.ts. This will cause import conflicts when both schemas are used in the same file.

The schema should be renamed to something more specific like ExternalFieldMappingSchema to avoid this collision and make the purpose clearer.

[Copilot]

The type export FieldMapping will also collide with the existing FieldMapping type from packages/spec/src/data/mapping.zod.ts. This should be renamed to ExternalFieldMapping to match the renamed schema.

[Copilot]

This JSON schema file will overwrite the existing FieldMapping.json that is generated from packages/spec/src/data/mapping.zod.ts.

The Zod schema naming collision (FieldMappingSchema exists in both external-lookup.zod.ts and mapping.zod.ts) causes this JSON schema file collision. Once the Zod schema is renamed to ExternalFieldMappingSchema, this JSON schema file should be renamed to ExternalFieldMapping.json.

[Copilot]

The localField property should enforce snake_case naming convention with a regex pattern, similar to how targetField is validated in packages/spec/src/integration/connector.zod.ts:219.

According to the coding guidelines and codebase conventions, machine names and field identifiers should be validated as snake_case. Please add the regex validation:

localField: z.string().regex(/^[a-z_][a-z0-9_]*$/).describe('Local field name (snake_case)'),

[Copilot]

The fieldName property should enforce snake_case naming convention with a regex pattern. The example in the JSDoc shows "external_account" which is snake_case, and this aligns with the coding guidelines that machine names should be in snake_case format.

Please add the regex validation:

fieldName: z.string().regex(/^[a-z_][a-z0-9_]*$/).describe('Field name (snake_case)'),

[Copilot]

The key property for template placeholders should enforce snake_case naming convention. The examples in the JSDoc show keys like "client_name" and "contract_date" which are snake_case, consistent with the coding guidelines for machine identifiers.

Please add the regex validation:

key: z.string().regex(/^[a-z_][a-z0-9_]*$/).describe('Placeholder key (snake_case)'),

[Copilot]

This documentation file appears to be incorrect. There is no packages/spec/src/data/connector.zod.ts file in the codebase. The FieldMappingSchema is actually exported from packages/spec/src/data/external-lookup.zod.ts, not from a connector module.

Additionally, there is a naming collision: FieldMappingSchema is defined in both:

1. packages/spec/src/data/external-lookup.zod.ts (newly added in this PR)
2. packages/spec/src/data/mapping.zod.ts (existing)

The schema in external-lookup.zod.ts should be renamed to avoid this conflict, perhaps to ExternalFieldMappingSchema, and this documentation file should either be removed or updated to reference the correct schema location.
