# HLZD Follow-up Sequencer

把"上次发件后第 N 天"自动转成"该发什么跟进邮件"。

## 阶段

| 距发件天数 | 阶段 | 动作 |
|---|---|---|
| 0-6 | `pending` | 不动 |
| 7-13 | `day_7_nudge` | 短提醒 — "上周一封信您看到了吗" |
| 14-20 | `day_14_followup` | 加 value + 主动约 call |
| ≥ 21 | `day_21_breakup` | 关闭循环 — "下季度再联系" |

## 用法

```bash
# 接 cold-outreach 输出
py scripts/cli.py --input outreach.json --output followups.json

# 测试场景 (override now date)
py scripts/cli.py --input outreach.json --as-of 2026-07-15
```

## Output schema

```json
{
  "$schema": "hlzd/followup-sequencer/v1",
  "report_date_utc": "2026-07-16T07:00:00Z",
  "summary": {
    "total_emails": 5,
    "actions_due": 3,
    "by_stage": {"day_7_nudge": 1, "day_14_followup": 1, "day_21_breakup": 1},
    "pending": 2,
    "errors": 0
  },
  "actions": [
    {
      "buyer": "Aramco Trading Co.",
      "contact": "Mr. Ahmed",
      "country": "SA",
      "stage": "day_7_nudge",
      "days_since_sent": 8,
      "subject": "Re: OCTG casing for Saudi",
      "body": "Hi Mr. Ahmed, ..."
    }
  ]
}
```

CLI exit code: 0 if no actions, 1 if actions due (cron-friendly).
