Coinbase Exchange WebSocket 序列与频道准备清单
本文正文暫以英文原文展示，翻譯版本需完成來源複核後再發布。
已验证事实边界
1. Coinbase Exchange WebSocket documentation describes feed access and connection behavior for exchange data. 2. Coinbase channel documentation provides channel-specific subscription and payload expectations. 3. Coinbase REST authentication documentation defines signed authenticated request material for private REST checks. 4. Coinbase order REST documentation is a separate evidence surface for order-state review. 5. A WebSocket channel event is not a full account audit unless the integration reconciles final state after gaps or disconnects. 6. A readiness checklist should separate requested channel, ordering signal, disconnect behavior, authenticated REST confirmation and non-secret logs.

文章表格：可橫向滑動，或聚焦表格區域後使用方向鍵。
| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Channel intent | different Coinbase channels answer different operational questions | write down why each subscribed channel is needed | whether a lower-detail channel is being mistaken for order truth |
| Ordering signal | sequence and message ordering determine whether local state can be trusted | pause automation and reconcile after any gap | whether the gap was caused by local backpressure |
| Connection behavior | a live socket does not guarantee complete state | monitor disconnects, close codes and resubscription success | whether silent network changes drop messages without a clean close |
| REST confirmation | authenticated REST checks can confirm account-specific order state after a feed issue | query final state after reconnect before placing replacement orders | whether REST rate limits delay recovery |
| Replay limit | old local events can become unsafe after a reconnect | discard stale local assumptions and rebuild from fresh evidence | whether the bot resumes with an old inventory view |
| Audit evidence | WebSocket logs are useful only when they avoid credentials and balances | store channel, sequence, timestamp, non-secret id and source URL only | whether logs reveal strategy timing or account exposure |

控制说明
1. Channel intent
这一项要求读者把公开来源翻译成操作规则。这里的含义是：different Coinbase channels answer different operational questions。可执行动作是：write down why each subscribed channel is needed。仍然未知的是：whether a lower-detail channel is being mistaken for order truth。因此本文不会把未知部分包装成收益承诺、牌照承诺、审批保证、安全保证、恢复保证、平台排名或价格暗示。
2. Ordering signal
这里的含义是：sequence and message ordering determine whether local state can be trusted。可执行动作是：pause automation and reconcile after any gap。仍然未知的是：whether the gap was caused by local backpressure。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
3. Connection behavior
这里的含义是：a live socket does not guarantee complete state。可执行动作是：monitor disconnects, close codes and resubscription success。仍然未知的是：whether silent network changes drop messages without a clean close。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
4. REST confirmation
这里的含义是：authenticated REST checks can confirm account-specific order state after a feed issue。可执行动作是：query final state after reconnect before placing replacement orders。仍然未知的是：whether REST rate limits delay recovery。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
5. Replay limit
这里的含义是：old local events can become unsafe after a reconnect。可执行动作是：discard stale local assumptions and rebuild from fresh evidence。仍然未知的是：whether the bot resumes with an old inventory view。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
6. Audit evidence
这里的含义是：WebSocket logs are useful only when they avoid credentials and balances。可执行动作是：store channel, sequence, timestamp, non-secret id and source URL only。仍然未知的是：whether logs reveal strategy timing or account exposure。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
仍需明确的未知项
- whether a lower-detail channel is being mistaken for order truth
- whether the gap was caused by local backpressure
- whether silent network changes drop messages without a clean close
- whether REST rate limits delay recovery
- whether the bot resumes with an old inventory view
- whether logs reveal strategy timing or account exposure
实用结论
Coinbase Exchange WebSocket 准备度应被视为逐频道证据计划，而不是一次连接测试。Coinbase 文档说明 exchange WebSocket feed、channel subscriptions 与各频道 payload；这些表面只有在集成记录已请求的频道、消息排序处理方式、断线后的处理方式，以及哪个 REST 或认证记录确认最终状态时才有用。实用结果是一份用于 channel intent、sequence continuity、heartbeat 或 connection monitoring、replay limits 与 gap 后对账的准备清单。 本文停在证据边界内，帮助读者决定下一步核验什么，而不是把公开文档改写成私人账户、钱包、API key、池子路径、稳定币余额、代币化资产或政策框架在任何未来条件下都能成功的承诺。
