I let an agent run unattended overnight. At 3am it emailed 400 customers the wrong thing.

说明与用途

一项无人值守的夜间对账流程因账本未完全写入而向400名客户发送错误的付款失败邮件，导致支持队列激增，凸显了在没有人工监督的情况下自动化不可逆操作的风险。

问题

Automated nightly reconciliation sent payment‑failure emails to 400 paying customers because the job mis‑identified successful payments as failures due to a half‑written ledger.

结果

The unattended automation caused a costly customer support incident, highlighting that automating the irreversible step (email send) without human oversight can lead to significant failures.

工作流

• Pull payment data from processor webhook
• Match processor records to internal ledger
• Identify payments marked as failed
• Draft failure notification emails
• Send emails to affected customers

证据

One night the reconciliation ran against a half‑written ledger. A batch of payments had been acknowledged by the processor's webhook before our own row had actually persisted — the save landed a few seconds late, and the 3am job read the gap as "these payments failed."

I saw the support queue at 9am, already two hundred tickets deep, from people who'd paid us and been told by our own software that they hadn't.
