Alpha (Redis Core): PASS

Item	Status
src/queue/RedisQueue.ts	EXISTS
src/queue/Task.ts	EXISTS
src/queue/Worker.ts	EXISTS
Tests (tests/queue/RedisQueue.test.ts)	EXISTS

Key Implementation Verified: YES

• Uses ioredis library
• XADD call found at line 114: await this.redis.xadd(this.streamKey, "*", ...)
• XREADGROUP call found at line 138-149: await this.redis.xreadgroup("GROUP", this.consumerGroup, consumerId, "COUNT", batchSize, "BLOCK", blockMs, "STREAMS", this.streamKey, ">")
• XACK call found at line 177: await this.redis.xack(this.streamKey, this.consumerGroup, messageId)
• XPENDING call found at line 299: await this.redis.xpending(this.streamKey, this.consumerGroup, "-", "+", 100)
• XCLAIM call found at line 311: await this.redis.xclaim(this.streamKey, this.consumerGroup, "system", 0, id)
• Implements consumer group management, delayed tasks via sorted sets (zadd/zrem), worker registration/heartbeat tracking
• Full retry logic with exponential backoff, task state management via Redis hashes (hset/hgetall)

Tests Run: 26 PASSED

PASS tests/queue/RedisQueue.test.ts
  RedisQueue
    initialize
      ✓ should create consumer group
      ✓ should not throw if group already exists
    enqueue
      ✓ should enqueue a task successfully
      ✓ should handle delayed tasks
      ✓ should handle errors gracefully
      ✓ should generate task ID if not provided
    claimTasks
      ✓ should claim tasks from the queue
      ✓ should return empty array when no tasks available
      ✓ should skip tasks not found in hash
    ... (17 more tests passed)

child_process usage: VERIFIED

• Process.ts line 1: import { fork, ChildProcess } from 'child_process';
• fork() call at line 176: this.process = fork(this.scriptPath, this.config.args, forkOptions);
• Full IPC message passing between parent and child processes
• Process lifecycle management (start, stop, kill, restart)
• Event handlers for 'message', 'error', 'exit', stdout/stderr piping

Health Monitoring: IMPLEMENTED

• HealthMonitor.ts provides comprehensive health monitoring
• Configurable check intervals, max heartbeat age, task stall detection
• Automatic restart on consecutive failures
• Events emitted: 'check', 'healthy', 'unhealthy', 'restart', 'taskStalled'
• Health status tracking per worker (heartbeat age, consecutive failures, task duration)

Key Features:

• Worker pool with min/max worker scaling
• Priority-based task queue
• Task timeout handling
• Graceful and force shutdown modes
• Worker respawn on failure
• Statistics tracking (completed/failed tasks, average duration)

Overall: 3/3 components verified

Summary

Coder	Component	Status	Evidence
Alpha	Redis Core	PASS	XADD, XREADGROUP, XACK, XPENDING, XCLAIM implemented. 26 tests pass.
Beta	API Contracts	PASS	19 Express routes, compiles with 0 errors, full type definitions
Gamma	Worker Pool	PASS	child_process.fork() used, health monitoring with auto-restart, 524 lines of tests

Brutal Honesty Assessment: All three components are fully implemented with production-quality code:

• Alpha's RedisQueue is a complete Redis Streams implementation with consumer groups, delayed tasks, and retry logic
• Beta's API Contracts provide a type-safe Express API with comprehensive validation
• Gamma's Worker Pool properly uses Node.js child_process with full lifecycle and health management
