验证构建的基础设施已真正接入系统而非仅完成代码。

确认基础设施是真正接入系统而不是只把代码写完：要沿调用链跑通功能、做烟雾测试并验证数据在真实路径上被使用。用于在合并、交付或标注任务完成前防止“建了没用”的死代码或未接通服务。特别强调可观测性和执行验证（trace、metrics、端到端测试），确保改动被实际触发和利用。

# Completion Check: Verify Infrastructure Is Wired

When building infrastructure, verify it's actually connected to the system before marking as complete.

## Pattern

Infrastructure is not done when the code is written - it's done when it's wired into the system and actively used. Dead code (built but never called) is wasted effort.

## DO

1. **Trace the execution path** - Follow from user intent to actual code execution:
   ```bash
   # Example: Verify Task tool spawns correctly
   grep -r "claude -p" src/
   grep -r "Task(" src/
   ```

2. **Check hooks are registered**, not just implemented:
   ```bash
   # Hook exists?
   ls -la .claude/hooks/my-hook.sh

   # Hook registered in setting
