Alerts must be verified at the recipient end: Configuring an email address and completing notification settings does not guarantee that the alert has been sent; a successful send response and the system’s acceptance for processing do not guarantee actual receipt; the alert is only truly operational once it has been received and processed—a read receipt is still required.

Is setting up an email address enough for backup failure alerts? How can I confirm that the alerts are actually received and being handled?

That's not enough. Configuring the recipient email address and verifying that the tool successfully sends the message are not the same as confirming that the recipient has actually received it. You should use a controlled test that does not affect production backups to verify alert delivery, confirm that the content clearly identifies the site and the error, and assign responsibility to...

Coexistence of verification records and business records: TXT records contain text for different applications, each with distinct usage rules; verification tokens serve to prove domain control, not email authorization; existing business values will continue to fulfill their original functions and must not be overwritten arbitrarily.

Sending, Receiving, and Verification

If a CDN or SaaS service requires a new verification TXT record, will this affect the existing TXT records in the corporate email system?

TXT records with different purposes can coexist under the same name according to their respective rules, but existing values must not be overwritten arbitrarily. When integrating a new service, verify the record name, value, and type before adding the necessary records and performing a read operation; in particular, do not add new domain names…

Rolling back data does not roll back actual transactions: Old backups preserve past states and may be missing new orders; payment platforms store actual transactions, which are not rolled back along with the website; business reconciliation involves verifying statuses across multiple systems and cannot rely solely on order counts.

WooCommerce Store

The online store has been restored to last night's backup. What about today's new orders? Handle the business time window before restoring.

Restoring an old database may overwrite new orders, payment statuses, and inventory changes that occurred after the backup point; however, actual transactions on the payment platform will not be lost as a result. You should first preserve the current data, define the business timeframe, and then develop a plan for reconciliation and recovery…

性能功能责任划分：分层互补，不同对象各司其职，仍需清理联动；同层重复，同一资源被多次转换，可能导致排除失效；功能责任图，记录实际输出来源，需覆盖主机与CDN

Page Caching and CDN

多个性能插件同时开启，怎样分配缓存、懒加载和CSS优化责任？

性能工具应按具体功能分配责任，而非按插件数量简单判断。整页缓存、资源处理、图片懒加载与CDN可能分属不同层，但同一种处理重复启用容易让输出和排除…

Auto-incrementing IDs and Data Integrity: Auto-incrementing IDs, which are technically assigned as primary keys, do not typically guarantee continuity; unique constraints prevent data conflicts, which is different from ensuring there are no gaps in the sequence; to restore integrity and ensure the correctness of records and relationships, one cannot rely solely on the maximum ID.

Server and Database

Does a discontinuity in IDs after restoring a database mean data has been lost? How do you verify auto-increment fields, unique keys, and business relationships?

Gaps in auto-incrementing IDs do not necessarily indicate missing records; mechanisms such as rollbacks, deletions, or concurrency can all affect the continuity of the sequence. During recovery verification, actual records, unique constraints, and business relationships should be compared; one should not force the auto-increment value by…

草稿审核按内容版本续接：生成稿，初始内容依据，不一定是最新审核稿；审核状态，具体检查完成情况，草稿存在不算审完；最小更新，只改当前待办字段，避免覆盖人工修改

媒体外置，备份也要延伸：数据库附件，记录路径与属性，不是原图文件；本地归档，只含实际取得文件，可能缺云端媒体；对象存储备份，保护远程文件，需独立恢复清单

Backup and Recovery

WordPress图片放到对象存储后，本地网站备份还包含原图吗

DKIM Selector Rotation: The selector identifies the public key in DNS, not the sender’s account; the DNS public key is provided for the recipient to verify the message but does not prove that the system has signed it; the signing private key is the sender’s confidential material and must not be disclosed to DNS.

Sending, Receiving, and Verification

When changing the DKIM key, can the DNS records for the old selector be deleted immediately?

The DKIM selector is used to locate the corresponding public key in DNS. When rotating keys, it is necessary not only to ensure that new messages begin using the new selector but also to account for old signatures that are still being delivered or verified. It is not sufficient to simply add a new record to DNS and declare a rotation…

First, list the scope of the push: File push, which updates programs and media, does not imply synchronization of settings; database push, which may overwrite business tables and cannot be merged by default; and custom scope, which reduces the number of objects affected but still requires checking for relationships.

WooCommerce Store

Will new orders placed on the WPvivid test site be merged with the main site when they're pushed back? Let's first look at who this applies to.

Merging is not automatic. Pushes from the test site may overwrite the files and database tables on the selected production site, and data added to the production site during testing may be replaced as a result. You should first determine whether you need to deploy code, media, or specific data…
