feat: complete all remaining protocol optimization items by Copilot · Pull Request #612 · objectstack-ai/objectstack

Copilot · 2026-02-11T07:28:17Z

Implements all remaining ⏳/❌ items from PROTOCOL_OPTIMIZATION_REPORT.md across 6 protocol domains. Adds 20 new schemas, 138 new tests (4518→4656), bringing Zod file count from 139→159.

UI Protocol (3 new files)

ui/touch.zod.ts — 7 gesture types (swipe/pinch/longPress/doubleTap/drag/rotate/pan), WCAG 44px touch targets, haptic feedback
ui/offline.zod.ts — 5 offline strategies (cache_first/network_first/stale_while_revalidate/network_only/cache_only), sync with conflict resolution, IndexedDB/LocalStorage/SQLite backends
ui/keyboard.zod.ts — Focus traps, keyboard shortcuts with 4 scopes (global/page/component/modal), roving tabindex
ui/theme.zod.ts extended with touchTarget + keyboardNavigation

API Protocol

api/contract.zod.ts — DataLoaderConfigSchema, BatchLoadingStrategySchema, QueryOptimizationConfigSchema for N+1 prevention
api/rest-server.zod.ts — WebhookEventSchema, WebhookConfigSchema, CallbackSchema, OpenApi31ExtensionsSchema

AI Protocol

ai/agent.zod.ts — StructuredOutputConfigSchema (json_object/json_schema/regex/grammar/xml formats + validation pipeline)
ai/mcp.zod.ts — MCPStreamingConfigSchema, MCPToolApprovalSchema, MCPSamplingConfigSchema, MCPRootsConfigSchema

Auth/Security

identity/scim.zod.ts — SCIM 2.0 Bulk Operations per RFC 7644 (SCIMBulkRequestSchema, SCIMBulkResponseSchema)
system/auth-config.zod.ts — MutualTLSConfigSchema (client certs, CA trust, CRL/OCSP, certificate pinning)
security/rls.zod.ts — RLSAuditEventSchema, RLSAuditConfigSchema (log level, destination, sample rate, retention)

Integration

integration/connector.zod.ts — ErrorMappingConfigSchema (8 error categories, unmapped behavior), HealthCheckConfigSchema, CircuitBreakerConfigSchema

Example

// N+1 query prevention
export const QueryOptimizationConfigSchema = z.object({
  preventNPlusOne: z.boolean().default(true),
  dataLoader: DataLoaderConfigSchema.optional(),
  batchStrategy: BatchLoadingStrategySchema.optional(),
  maxQueryDepth: z.number().int().min(1).default(5),
  queryComplexityLimit: z.number().int().optional(),
  enableQueryPlan: z.boolean().default(false),
});

PROTOCOL_OPTIMIZATION_REPORT.md updated to reflect all completions (rating: 4.2→4.8/5).

Pull request overview

This pull request implements comprehensive protocol enhancements across UI, API, AI, Auth/Security, Integration, and Identity domains as part of the PROTOCOL_OPTIMIZATION_REPORT.md initiative. The changes add critical features for accessibility, offline-first applications, API performance optimization, AI structured outputs, zero-trust security, resilient integrations, and enterprise identity management.

Changes:

UI Protocol: Added touch interaction schemas (WCAG 2.5.5 compliant touch targets, gestures), keyboard navigation (focus management, shortcuts, roving tabindex), and offline support (cache-first/network-first strategies, conflict resolution, sync configuration)
API Protocol: Implemented DataLoader/N+1 query prevention schemas, OpenAPI 3.1 webhooks and callbacks for asynchronous API patterns
AI Protocol: Added structured output configuration (JSON Schema validation, retry logic, transform pipelines) and extended MCP protocol (streaming, tool approval, sampling, roots configuration)
Auth/Security Protocol: Introduced mutual TLS (mTLS) support for zero-trust architectures and RLS audit logging for compliance tracking
Integration Protocol: Added error mapping patterns, health checks, and circuit breaker configurations for resilient connectors
Identity Protocol: Implemented SCIM 2.0 bulk operations (RFC 7644 §3.7) for batch user/group provisioning

+export const ErrorMappingConfigSchema = z.object({
+  rules: z.array(ErrorMappingRuleSchema).describe('Error mapping rules'),
+  defaultCategory: ErrorCategorySchema.optional().default('integration_error').describe('Default category for unmapped errors'),
+  unmappedBehavior: z.enum(['passthrough', 'generic_error', 'throw']).describe('What to do with unmapped errors'),


The unmappedBehavior field in ErrorMappingConfigSchema is required, which means users must always specify it when configuring error mapping. Consider adding a sensible default (e.g., default('generic_error')) to make the configuration more developer-friendly while still allowing explicit overrides. This would align with the pattern used for other similar configuration options like defaultCategory.

Suggested change

unmappedBehavior: z.enum(['passthrough', 'generic_error', 'throw']).describe('What to do with unmapped errors'),

unmappedBehavior: z.enum(['passthrough', 'generic_error', 'throw']).optional().default('generic_error').describe('What to do with unmapped errors'),

+
+  /** Certificate validation strictness level */
+  certificateValidation: z.enum(['strict', 'relaxed', 'none'])
+    .describe('Certificate validation strictness level'),


The trustedCAs and certificateValidation fields are required in MutualTLSConfigSchema. While this ensures explicit configuration, consider making trustedCAs default to an empty array and certificateValidation default to 'strict' for better developer experience. This would allow minimal configuration while maintaining security by default. The current design requires all users to specify these even when they want defaults.
