+## 1. Missing Critical Protocols / 缺失的关键协议
+
+### 1.1 Database & Storage Protocols
+
+#### GraphQL Protocol (Priority: ⭐⭐⭐)
+**File**: `packages/spec/src/api/graphql.zod.ts`
+
+```typescript
+import { z } from 'zod';
+
+/**
+ * GraphQL schema generation configuration
+ * Maps ObjectQL schemas to GraphQL types
+ */
+export const GraphQLTypeSchema = z.object({
+  typeName: z.string(),
+  description: z.string().optional(),
+  fields: z.record(z.object({
+    type: z.enum(['String', 'Int', 'Float', 'Boolean', 'ID', 'Custom']),
+    list: z.boolean().default(false),
+    nullable: z.boolean().default(true),
+    customType: z.string().optional(),
+  })),
+});
+
+export const GraphQLQueryConfigSchema = z.object({
+  enabled: z.boolean().default(true),
+  operationName: z.string(),
+  returnType: z.string(),
+  args: z.record(z.string()).optional(),
+  complexity: z.number().optional(),
+});
+
+export const GraphQLMutationConfigSchema = z.object({
+  enabled: z.boolean().default(true),
+  operationName: z.string(),
+  inputType: z.string(),
+  returnType: z.string(),
+});
+
+export const GraphQLSubscriptionConfigSchema = z.object({
+  enabled: z.boolean().default(false),
+  eventName: z.string(),
+  filter: z.string().optional(),
+  payload: z.string(),
+});
+
+export const GraphQLConfigSchema = z.object({
+  enabled: z.boolean().default(false),
+  endpoint: z.string().default('/graphql'),
+  playground: z.boolean().default(true),
+  introspection: z.boolean().default(true),
+  queryDepthLimit: z.number().default(10),
+  complexityLimit: z.number().default(1000),
+  queries: z.array(GraphQLQueryConfigSchema).optional(),
+  mutations: z.array(GraphQLMutationConfigSchema).optional(),
+  subscriptions: z.array(GraphQLSubscriptionConfigSchema).optional(),
+});
+
+export type GraphQLConfig = z.infer<typeof GraphQLConfigSchema>;
+```
+
+**Rationale / 原因**:
+- Hasura and Prisma prove GraphQL is essential for modern data APIs
+- Type-safe schema generation from ObjectQL definitions
+- Automatic resolver generation based on permissions
+

+
+```typescript

+});
+
+export type CacheConfig = z.infer<typeof CacheConfigSchema>;
+```

+#### Object Storage Protocol (Priority: ⭐⭐)
+**File**: `packages/spec/src/system/object-storage.zod.ts`
+
+```typescript
+import { z } from 'zod';
+
+/**
+ * Object storage protocol for file/blob management
+ * Compatible with S3, Azure Blob, GCS, MinIO
+ */
+export const StorageProviderSchema = z.enum([

+  'azure-blob',
+  'gcs',
+  'minio',
+  'local',
+]);
+
+export const BucketConfigSchema = z.object({
+  name: z.string(),

+});
+
+export const PresignedUrlConfigSchema = z.object({
+  expiration: z.number().default(3600).describe('Expiration in seconds'),
+  allowedOperations: z.array(z.enum(['get', 'put', 'delete'])),
+});
+
+export const ObjectStorageConfigSchema = z.object({
+  provider: StorageProviderSchema,
+  accessKeyId: z.string().optional(),
+  secretAccessKey: z.string().optional(),
+  endpoint: z.string().optional(),
+  buckets: z.array(BucketConfigSchema),

+  presignedUrls: PresignedUrlConfigSchema.optional(),
+});
+
+export type ObjectStorageConfig = z.infer<typeof ObjectStorageConfigSchema>;
+```
+

+
+#### Message Queue Protocol (Priority: ⭐⭐)
+**File**: `packages/spec/src/system/message-queue.zod.ts`
+
+```typescript
+import { z } from 'zod';
+
+/**
+ * Message queue protocol for async communication
+ * Supports Kafka, RabbitMQ, AWS SQS, Redis Pub/Sub
+ */
+export const MessageQueueProviderSchema = z.enum([

+  'rabbitmq',
+  'aws-sqs',
+  'redis-pubsub',
+  'google-pubsub',
+  'azure-service-bus',
+]);
+
+export const TopicConfigSchema = z.object({
