Each significant variant gets its own row. A variants array on the parent holds the slugs of cousins, and a list mapping renders See also from the parent to each variant. The Observer page links to Publish-Subscribe and Event Aggregator; each variant page links back to Observer. The graph stays bidirectional because both sides read from the same source column.

Yes. Add a diagram_url or inline_svg column. The base page reserves a slot rendered by a selector that injects either an image or inline SVG. Patterns with a hand-drawn diagram show it; patterns without a diagram skip the slot. The same column can carry PlantUML source if you render diagrams at build time.

No, one template handles both because the structure is the same. The family column drives conditional rendering: a circuit-breaker page surfaces a failure-mode diagram slot that a strategy page hides. Conditional Twig in the base template handles family-specific blocks without forking the whole template.

Yes for internal wikis. Add a services array column with the service names that apply the pattern. A list mapping renders Used in section on each pattern page. Run the same sheet behind a private SleekRank instance for the engineering wiki, and a public version with services column hidden for the marketing-facing catalog.

Implementations live as a JSON object on each row. Sweeping language updates (Python 3.8 to 3.12, Java 8 to 21) become a column transform in the sheet rather than 200 article edits. CI can validate samples against unit tests in a separate repo if you want enforced correctness, with the sheet pulling from the test repo's tagged source.

TechArticle and HowTo schemas cover the structural data Google uses for rich results, but ranking depends on authority, depth, and freshness. SleekRank handles the technical baseline. The pattern catalog still has to win on content quality, which is easier when editorial effort goes into intent and code samples instead of HTML repetition.

Yes through standard WordPress comments on the base page, which renders comments per generated URL. If you want threaded discussion with code highlighting, an embed of a third-party commenting service works the same way: include the embed script in the base page and it scopes to the generated page's URL automatically.

Pattern pages live under /patterns/ via SleekRank; the blog under /blog/ keeps its own template; case studies under /case-studies/ link out from pattern pages via a case_studies slug array. Three content types, three URL families, one site, mutually cross-linked through slug columns in the source sheets.
