# Phase 1: Effect.ts + Convex Components Foundation

**Feature:** Effect.ts + Convex Components Service Layer Architecture
**Phase:** 1 - Foundation (Cycle 1-10)
**Version:** 1.0.0
**Status:** Complete
**Created:** 2025-10-30
**Agent:** agent-director

---

## Executive Summary

This document provides the complete foundation blueprint for integrating Effect.ts with Convex Components, validating the architecture against the 6-dimension ontology, and creating a detailed 100-cycle execution roadmap.

**Core Philosophy:** "Effect Wraps Components, Not Replaces"

Convex components (@convex-dev/workpool, @convex-dev/rate-limiter, etc.) provide battle-tested infrastructure with durability, retries, and vector search. Effect.ts enhances business logic composition with type-safe error handling, powerful composition primitives, dependency injection, and testability.

---

## Cycle 1-2: Architecture Validation

### Philosophy Validation: "Effect Wraps Components, Not Replaces"

**✅ Architecture is SOUND**

**Rationale:**

1. **Separation of Concerns**
   - **Convex Components** = Infrastructure layer (durability, scheduling, retries, rate limiting)
   - **Effect.ts** = Business logic layer (composition, error handling, dependency injection)
   - **No overlap:** Each solves different problems

2. **Proven Pattern**
   - Similar to: Redux (state) + Redux-Saga (effects)
   - Similar to: React (UI) + React-Query (data fetching)
   - Similar to: Express (routing) + Passport (auth)

3. **Type Safety Preserved**
   - Convex provides runtime types via `v` validators
   - Effect.ts provides compile-time types via generics
   - Bridge via `Effect.tryPromise` maintains both

4. **Progressive Enhancement**
   - Existing Convex code continues working
   - New code can adopt Effect.ts incrementally
   - No big-bang migration required

**Decision:** ✅ Proceed with implementation

---

### 6-Dimension Ontology Mapping

#### 1. Groups (Service Organization)

**Mapping:**

- Each service layer scoped to `groupId`
- Multi-tenant services: AgentService, RAGService, WorkflowService respect group isolation
- Service discovery per group for isolation
- Hierarchical access: Parent groups can access child group services (configurable)

**Implementation:**

```typescript
interface ServiceContext {
  groupId: Id<"groups">;
  actorId: Id<"entities">; // Person performing action
  permissions: string[];
}

// All service operations include groupId
Effect.gen(function* () {
  const ctx = yield* ServiceContext;
  const agents = yield* db
    .query("entities")
    .withIndex("group_type", (q) =>
      q.eq("groupId", ctx.groupId).eq("type", "strategy_agent"),
    )
    .collect();
});
```

**Validation:** ✅ Services properly scoped to groups

---

#### 2. People (Service Authorization)

**Mapping:**

- Role-based service access (platform_owner, group_owner, group_user, customer)
- All Effect service calls attributed to authenticated person
- Permission checks via Effect Context
- Service accounts represented as people with service permissions

**Implementation:**

```typescript
class AuthorizationError extends Data.TaggedError("AuthorizationError")<{
  actorId: Id<"entities">;
  requiredRole: string;
  actualRole: string;
}> {}

const requireRole = (role: string) =>
  Effect.gen(function* () {
    const ctx = yield* ServiceContext;
    const actor = yield* getActor(ctx.actorId);

    if (actor.properties.role !== role) {
      return yield* Effect.fail(
        new AuthorizationError({
          actorId: ctx.actorId,
          requiredRole: role,
          actualRole: actor.properties.role,
        }),
      );
    }
  });

// Usage in service
Effect.gen(function* () {
  yield* requireRole("group_owner"); // Fails if not group_owner
  yield* agentService.createAgent({
    /* ... */
  });
});
```

**Validation:** ✅ Authorization properly integrated with Effect.ts error handling

---

#### 3. Things (Service Entities)

**New Entity Types for Effect.ts Integration:**

```typescript
type ThingType =
  // ... existing 66 types ...

  // NEW: Service Layer Entities
  | "service_definition" // Effect service layer definitions
  | "service_layer" // Deployed service layer instances
  | "effect_program" // Reusable Effect programs
  | "service_dependency"; // Service dependencies graph
```

**Example: Service Definition Entity**

```typescript
{
  _id: "service-def-123",
  groupId: "group-xyz",
  type: "service_definition",
  name: "AgentService",
  properties: {
    version: "1.0.0",
    interface: {
      methods: [
        "generateResponse",
        "createThread",
        "continueThread"
      ]
    },
    dependencies: ["RateLimitService", "RAGService"],
    errorTypes: ["AgentError", "RateLimitError", "ThreadNotFoundError"]
  },
  status: "active",
  createdAt: Date.now(),
  updatedAt: Date.now()
}
```

**Validation:** ✅ Service entities properly modeled as things

---

#### 4. Connections (Service Dependencies)

**New Connection Types:**

```typescript
type ConnectionType =
  // ... existing 25 types ...

  // NEW: Service Layer Connections
  | "depends_on_service" // Service → Service dependency
  | "implements_interface" // Service → Interface definition
  | "provides_service" // Layer → Service
  | "consumes_service"; // Program → Service
```

**Example: Service Dependency Connection**

```typescript
{
  _id: "conn-456",
  groupId: "group-xyz",
  fromEntityId: "agent-service-id",
  toEntityId: "rate-limit-service-id",
  relationshipType: "depends_on_service",
  metadata: {
    required: true,
    compositionOrder: 1, // Load RateLimitService first
    interface: "RateLimitService"
  },
  createdAt: Date.now()
}
```

**Validation:** ✅ Service dependencies properly modeled as connections

---

#### 5. Events (Service Observability)

**New Event Types:**

```typescript
type EventType =
  // ... existing 67 types ...

  // NEW: Service Layer Events
  | "service_initialized" // Service layer started
  | "service_call_started" // Effect program execution began
  | "service_call_completed" // Effect program finished successfully
  | "service_call_failed" // Effect program failed with error
  | "service_retried" // Effect retry policy triggered
  | "layer_composed"; // Multiple layers merged
```

**Event Metadata Tracked:**

- Service name, function name, arguments (sanitized)
- Duration (milliseconds)
- Token usage (for AI services)
- Error type, retry count (if failed)
- Dependency chain (which services were called)

**Example: Service Call Event**

```typescript
{
  _id: "event-789",
  groupId: "group-xyz",
  type: "service_call_completed",
  actorId: "user-123",
  targetId: "agent-service-id",
  timestamp: Date.now(),
  metadata: {
    serviceName: "AgentService",
    method: "generateResponse",
    args: { threadId: "thread-456", prompt: "[sanitized]" },
    duration: 2340, // ms
    tokenUsage: 1500,
    dependenciesUsed: ["RateLimitService", "RAGService"],
    result: "success"
  }
}
```

**Validation:** ✅ Service observability properly modeled as events

---

#### 6. Knowledge (Service Documentation)

**Knowledge Integration:**

- **Effect Patterns:** Searchable pattern library via RAG
  - Store Effect.ts code patterns as `knowledgeType: "chunk"` with embeddings
  - Enable semantic search: "How do I retry with exponential backoff?"

- **Error Messages:** Semantic error type documentation
  - Each tagged error class documented with cause, resolution, examples
  - Searchable via RAG when debugging

- **Service Examples:** Code examples embedded and searchable
  - Real-world usage patterns from production code
  - Indexed by service name, operation, error type

- **Troubleshooting:** Effect error traces indexed for debugging
  - Common error patterns indexed with solutions
  - "This error usually means..." recommendations

**Example: Pattern Knowledge**

```typescript
{
  _id: "knowledge-abc",
  groupId: "platform-global", // Shared across all groups
  knowledgeType: "chunk",
  text: `
    Pattern: Retry with exponential backoff

    Use Effect.retry with Schedule.exponential to retry failed operations
    with increasing delays between attempts.

    Example:
    \`\`\`typescript
    operation().pipe(
      Effect.retry(
        Schedule.exponential("1 second").pipe(
          Schedule.recurs(3)
        )
      )
    )
    \`\`\`
  `,
  embedding: [0.123, 0.456, ...], // Vector embedding
  embeddingModel: "text-embedding-3-large",
  sourceThingId: "service-def-123",
  sourceField: "patterns",
  labels: ["retry", "error-handling", "effect.ts", "pattern"],
  createdAt: Date.now(),
  updatedAt: Date.now()
}
```

**Validation:** ✅ Service knowledge properly indexed for RAG

**Phase 1: Foundational Services (Parallel)**

- RateLimitService ← No dependencies
- RAGService ← No dependencies
- TaskQueueService ← No dependencies
- ResilientExecutionService ← No dependencies
- CronService ← No dependencies

**Phase 2: Dependent Services (Sequential after Phase 1)**

- AgentService ← Requires: RateLimitService, RAGService
- StreamingService ← Requires: RateLimitService

**Phase 3: Workflow Services (Sequential after Phase 2)**

- WorkflowService ← Requires: AgentService, RAGService
