Launch HN：HyperProbe（YC S26）——可在生产环境进行只读调试的 Agent
英文标题：🔶 Launch HN: HyperProbe (YC S26) – Agents that do read-only debugging in prod
HyperProbe 推出可在生产环境中执行只读调试的 Agent，能够在 Webhook 触发的精确时刻捕获实时请求快照。示例显示，支付网关发送了代码未处理的 `PENDING` 状态，而幂等性逻辑在确认状态前就将支付标记为已处理。结果是支付既未写入数据库，也因 Redis 中的幂等性标记而被永久阻止再次处理。该类实时快照可帮助开发者定位不会抛出异常、却会造成业务数据丢失的生产环境逻辑缺陷。

快照会在 Webhook 触发的精确时刻捕获实时请求。
Gateway 正在发送 PENDING。代码中没有处理它的分支。幂等性检查在确认状态之前就将支付标记为已处理。支付从未写入数据库。没有触发任何异常。
实时快照 · webhooks.ts:78 · 捕获于 02:50:14 UTC
status = "PENDING" ← 支付网关正在发送此状态，但不存在对应处理程序
duplicate = null ← 首次出现，通过检查
db.insert → 从未调用
redis.set → 仍然被调用，导致该支付被永久锁定、无法再次处理
支付网关开始发送 PENDING，而你的代码从未处理这一状态。幂等性键在检查状态之前就被写入。支付被标记为已处理，却从未被记录。
English / 原文
Snapshot captures live request at the exact moment the webhook fires.
Gateway is sending PENDING. The code has no case for it. Idempotency check marks payment as processed before confirming state. Payment never written to DB. No exception fires.
Live snapshot · webhooks.ts:78 · captured 02:50:14 UTCstatus = "PENDING" ← payment gateway sending this, no handler exists
duplicate = null ← first time seen, passes through
db.insert → never called
redis.set → called anyway, payment locked out permanently
Payment gateway started sending PENDING, a status your code never handled. Idempotency key written before state is checked. Payment marked processed, never recorded.
