Fix dangling #website reference and bind WebPage isPartOf/inLanguage

[workprentice]

What

Fixes a dangling @id reference and completes the WebPage container's binding to the site entity in the @graph structured data builder.

The bug

Every collector partial that emits isPartOf — most visibly blog-entity.html, which runs on all 809 blog posts — points at "https://www.pulumi.com/#website". That @id was only ever defined inside the .IsHome branch of graph-builder.html. On every non-home page, the else branch appended only $orgMinimal — no WebSite node at all — so isPartOf resolved to nothing in that page's own @graph.

Google's structured-data parser and AI/LLM extractors evaluate each URL's JSON-LD independently; they do not dereference @id links across pages. So this was a dangling reference on roughly 2,500+ non-home content pages, 809 of them blog posts.

Separately, the root WebPage container ($webpage, defined at the top of the file) never bound itself to the site entity or declared its language: no isPartOf, no inLanguage, on any page — including the homepage.

The fix

Two edits, one file (layouts/partials/schema/graph-builder.html):

1. Add a lean $websiteMinimal WebSite node in the non-home branch, mirroring the existing $orgMinimal precedent immediately above it. Shares the same @id/url/name/alternateName/description/inLanguage/publisher as the homepage's rich WebSite node, so the two cannot drift out of sync.
2. Merge isPartOf + inLanguage onto $webpage before it's appended to the graph, using the file's established merge $webpage (dict ...) idiom already used for description/breadcrumb/mainEntity/hasPart. This resolves on the homepage (rich node) and every other page (new lean node) alike.

Deliberate omissions (documented so no one re-litigates these)

• about / mentions on the new lean WebSite node — that's homepage entity-definition payload (the "what is Pulumi" Thing and competitor/technology mentions list) and would bloat every single page unnecessarily. It stays on the homepage's rich node only.
• potentialAction / SearchAction — grepped the repo; zero SearchAction usage exists today. Google retired the sitelinks search box feature, so adding one here would not be an improvement, on this page or any other.

Verification

• grep -rn 'isPartOf|#website' layouts/ confirms no other dangling #website reference exists. The four isPartOf sites in utils/product-entities.html point at a different, self-describing embedded object (https://www.pulumi.com/product/#pulumi-platform, with its own inline @type/name) rather than a bare cross-graph @id — so they are not affected by this class of bug and needed no change.
• Brace-balance check on graph-builder.html: {{ / }} counts go from 103/103 (baseline, origin/master) to 107/107 (this change) — balanced.
• git diff --stat confirms a single file, 28 insertions, 0 deletions.
• Test-merged this branch against open PR fix(schema): mirror title_tag instead of sidebar .Title in JSON-LD names #20630 (which touches the same file, ~127 lines away at line 10): auto-merged cleanly with no conflicts, so merge order between the two PRs doesn't matter.
• Local hugo --minify build was attempted for full render verification but fails before reaching any page render, at the CSS asset-fingerprinting step in assets.html — this environment doesn't have the Node asset pipeline built (make ensure requires Node/Yarn, unavailable here). That failure is unrelated to this change (it's in the CSS pipeline, not schema partials) and pre-exists on origin/master in this environment. Full render verification defers to CI (Install deps and build site, test matrix).

Impact

• 809 blog posts: isPartOf now resolves to a real node in their own @graph, instead of a dangling reference.
• ~2,500+ non-home content pages: gain a resolvable WebSite node for the first time.
• All pages, including the homepage: WebPage container now declares isPartOf and inLanguage, completing its identity binding to the site entity.

Pre-merge Review — Last updated 2026-08-02T12:16:10Z

Tip

Summary: This is a template-only change to the JSON-LD @graph builder (layouts/partials/schema/graph-builder.html): it binds isPartOf/inLanguage onto every page's WebPage node and, on non-home pages, appends a lean WebSite node so the https://www.pulumi.com/#website @id that collectors reference actually resolves within each page's own graph. The wrongness that would matter here is structured data that emits differently than the code comments describe, or a @id that still dangles — either sends wrong entity signals to Google and AI crawlers site-wide, across every non-home URL. The emitted graph logic itself checks out: the else branch covers every non-home page, $websiteMinimal mirrors the homepage node's @id, and the merge at L138 doesn't clobber any previously-set key. Two findings are about the new comment block describing its own code inaccurately. Passes that ran: infra/template review of the changed partial, a repo-wide check of isPartOf / #website emitters, and a fact-check pass over the diff's claim candidates (all four resolved as @id anchors rather than external assertions). No Hugo build preflight ran for this PR, and make build / make lint are separate jobs.

Review confidence:

Dimension	Level	Notes
mechanics	MEDIUM	Template logic reviewed by reading, but no rendered-output check ran — the Hugo preflight was skipped this run, so the emitted JSON-LD wasn't inspected on a real page.
facts	MEDIUM	The comment's traffic counts (~2,500+ non-home URLs, 809 blog posts) and the claim that Google retired the sitelinks search box weren't independently confirmed; they don't affect the emitted schema.

🚨 Outstanding in this PR

These must be resolved or refuted before merging.

• [L341-343] layouts/partials/schema/graph-builder.html "sharing its @id/url/name/alternateName/description/inLanguage/publisher so the two cannot drift out of sync" — ⚔️ the new node doesn't share those fields; it copies them. $websiteMinimal (L348-357) re-declares url, name, alternateName, description, inLanguage, and publisher as its own string literals, so editing the homepage $website node (L224-232) leaves this one stale and the two nodes drift silently — exactly the failure the comment says is impossible. The $orgMinimal block this one says it mirrors does it the other way: description/foundingDate/sameAs come from $orgDescription/$orgFoundingDate/$orgSameAs, hoisted once at L150-161 for that reason. Either hoist the shared WebSite values the same way, or drop the "cannot drift" wording. Hoisting is the smaller change and keeps the file's established pattern:

  {{/* Shared WebSite identity fields, defined once and reused by both the
       homepage's rich WebSite node and every non-home page's minimal node
       below, so the two cannot drift out of sync. */}}
  {{ $siteName := "Pulumi" }}
  {{ $siteAlternateName := "Pulumi IaC Platform" }}
  {{ $siteDescription := "Infrastructure as Code platform with AI. Deploy to any cloud using TypeScript, Python, Go, C#, Java, or YAML." }}
  

  …declared alongside $orgSameAs (before the {{ if .IsHome }} split), then referenced from both $website and $websiteMinimal in place of the literals.

• [L333-334] layouts/partials/schema/graph-builder.html "Collector partials (e.g. blog-entity.html) emit "isPartOf": {"@id": "https://www.pulumi.com/#website\"} on every content page" — ⚔️ only blog posts did. Searching layouts/ for isPartOf turns up a single pre-existing emitter of that @id: layouts/partials/schema/collectors/blog-entity.html:34, which runs on blog posts only. The four hits in schema/utils/product-entities.html (L20, 33, 47, 60) set isPartOf to other targets, not #website. So the dangling reference this PR fixes was real but scoped to blog posts — it's L138 of this same diff that newly makes every page emit isPartOf: #website, which is what actually justifies defining the node site-wide. Suggested rewrite:

  {{/* Add a lean per-page WebSite node on every non-home page. The WebPage
       node above now carries "isPartOf": {"@id":
       "https://www.pulumi.com/#website"} on every page, and
       blog-entity.html has always emitted the same reference on blog
       posts — but that @id was only ever defined inside the .IsHome
       branch above, so on every non-home URL isPartOf pointed at a node
       absent from that page's own @graph. */}}
