## Attribution, when you cite

    Silent Failure Catalog, <entry-id> "<entry title>", Xinghua Zhao (Steven Zhao·China), <as-of date>. All rights reserved.

**Note on attribution practice.** This catalog deliberately uses `as of` dates on every entry.
When you cite an entry, cite the entry id, the title, and the `as of` date. A fix can regress;
an undated citation becomes a false claim over time.
