## Task Status: Redis Queue Core (Task 1)

**Agent:** Coder-Alpha

**Status:** Complete

**Worktree:** `/home/ani/Projects/community-ade-wt/queue-core`

**Completed Files:**
- `src/queue/Task.ts` - Task interface with types, serialization, and retry logic
- `src/queue/RedisQueue.ts` - Redis Streams implementation with consumer groups
- `src/queue/Worker.ts` - Worker claiming tasks with heartbeats and WorkerPool
- `src/index.ts` - Main exports for the module
- `tests/queue/RedisQueue.test.ts` - Unit tests (26 tests passing)
- `package.json` - Dependencies (ioredis, uuid, TypeScript, Jest)
- `tsconfig.json` - TypeScript configuration
- `jest.config.js` - Jest test configuration

**Blockers:** None

**Next:** Integration with other components after merge

**Time Remaining:** 0 minutes (completed on schedule)

### Implementation Details

#### Key Features Implemented:

1. **Redis Streams Queue** (`RedisQueue.ts`)
   - Consumer group: `ade-workers`
   - Stream key: `ade:queue:tasks`
   - Commands used: XADD, XREADGROUP, XACK, XCLAIM, XPENDING
   - Supports delayed tasks via Sorted Set (`ade:queue:delayed`)

2. **Task State Management** (`Task.ts`)
   - Task states: pending, claimed, running, completed, failed, cancelled
   - Exponential backoff with jitter for retries
   - Serialization/deserialization for Redis storage
   - Constants: HEARTBEAT_INTERVAL_MS=5000, HEARTBEAT_TIMEOUT_MS=30000

3. **Worker Implementation** (`Worker.ts`)
   - Worker heartbeat every 5 seconds
   - Automatic task claiming from consumer group
   - Concurrent task processing with configurable limits
   - Graceful shutdown with optional task completion
   - WorkerPool for managing multiple workers

4. **Retry Logic**
   - Exponential backoff: baseDelay * (multiplier ^ attempt)
   - Jitter: ±10% to prevent thundering herd
   - Configurable max attempts (default: 3)
   - Max delay cap: 5 minutes

#### Test Results:
- 26 tests passing
- Coverage includes: enqueue, claim, complete, fail, retry, delayed tasks, worker registration

#### Dependencies:
- `ioredis` - Redis client
- `uuid` - UUID generation
- TypeScript, Jest, ts-jest for development
