feat(adp): citation-bait schema fields + FAQPage emission#397
Conversation
Add three optional Pattern fields (relatedQuestions, keyStatistic, expertQuote) and a dedicatedDateModified field on Posts. Render the three Pattern fields as visible (not collapsed) callouts/blockquote/Q&A on satellite pages. Emit FAQPage JSON-LD when relatedQuestions is populated. The Posts dedicatedDateModified field is set by a beforeChange hook only when body/title/summary changes, replacing the over-firing updatedAt as the dateModified signal in BlogPosting schema. This PR ships template infrastructure only -- no pattern data files are populated with the new fields. Closes #389

Specific praise
The schemas-array spread-and-filter pattern in [slug]/page.tsx (...(faqSchema ? [faqSchema] : [])) is a clean way to keep the conditional emission readable — better than mutating the array post-hoc or branching on the JSX side. Worth holding as a template for future optional top-level schemas.
Bottom line
The FAQ schema emission, type additions, and visible Q&A/quote/stat renderers are correct and well-isolated. The blocking concern is the beforeChange hook: as written, it stamps dedicatedDateModified exactly once per post and then permanently freezes it because of the partial-vs-full data semantics in Payload. The schema fallback prevents a null dateModified, but the signal-freshness goal of this PR is undermined. Recommend fixing the hook (and adding tests so the next refactor does not regress) before merging.

IMPORTANT — the auto-stamp only fires on the first content edit of any post, then is frozen permanently.
data here is a Payload Partial<T> containing only the fields the editor touched in this save (per Payload docs on beforeChange: "On updates, contains only fields being changed"). When the editor edits body but does not touch dedicatedDateModified, data.dedicatedDateModified is undefined. If originalDoc.dedicatedDateModified is already set (e.g. from a prior content edit), this comparison evaluates undefined !== "2026-05-10T..." → editorSetField = true → hook returns early without re-stamping.
Concrete walkthrough:
- First content edit on a post with
dedicatedDateModified = null: comparison isundefined !== null→ falsy in JS? No —undefined !== nullistruestrictly, so this returns early too. Actually the field probably starts asundefinedon legacy posts, in which caseundefined !== undefinedisfalseand stamping proceeds the first time. After it stamps,originalDoc.dedicatedDateModifiedbecomes a string on subsequent loads. - Second content edit: comparison is
undefined !== "<previous-ISO>"→true→ returns early.dedicatedDateModifiedis never updated again, even though body changed.
Net effect: the JSON-LD BlogPosting.dateModified gets stuck on the first stamp and slowly drifts from reality — defeating the citation-freshness signal this PR is trying to build. The ?? fallback in blog-posting.ts papers over the symptom (no null emitted), but the signal quality degrades.
To detect the case "editor explicitly set this field in this save," you need to check whether dedicatedDateModified is present as a key in data (the delta), not whether its value differs from originalDoc. One option:
const editorSetField = data !== undefined && "dedicatedDateModified" in dataThis treats "editor touched the field" as the key being present in the delta — regardless of value. Worth confirming against a manual save in the admin UI before shipping.
Related: the MEANINGFUL_FIELDS.some(...) check has the same partial-vs-full confusion — JSON.stringify(data?.body) is undefined when body is unchanged (omitted from delta), JSON.stringify(originalDoc.body) is the full Lexical AST, so they always differ. This makes changed over-eager (false-positive). The over-eagerness happens to push in the right direction (auto-stamp on save) but it means the hook stamps on any save where editorSetField is false, not just body/title/summary edits. Fixing #1 should also fix this check to use the same in-delta semantics.
No tests exist for this hook — see the separate SUGGESTION about coverage.

SUGGESTION — the 12 new unit tests in this PR are all for generateFaqPageSchema. The beforeChangeDedicatedDateModified hook has more behaviorally subtle semantics (create vs update, partial-vs-full data, editor-override path) and zero coverage. A unit test that mocks data as a Payload Partial<Post> for each path — first stamp, second stamp on body change (catches the bug flagged in the other comment), editor manual override, no-op save with non-content fields changed (e.g. featured flag flip) — would lock down the contract this hook is meant to enforce.

SUGGESTION — Google deprecated FAQ rich results in Search on 2026-05-07 (the rich result, not the schema itself). The FAQPage JSON-LD is still valuable for AI search engines (Perplexity, ChatGPT, Gemini, Google AI Overviews) which parse it as a primary citation signal. But the comment here and the similar one in RelatedQuestionsBlock.tsx:6-7 cite "rich-result eligibility" as the rationale, which is no longer accurate. Worth refreshing the rationale to "AI-search citation signal" or similar so the next reader does not get confused about why this exists.
…fied hook The beforeChange hook compared data.dedicatedDateModified !== originalDoc?.dedicatedDateModified to detect editor-supplied values, but Payload's `data` on update contains only fields the editor touched. On normal body edits the field is undefined in the partial; the comparison evaluates true against any prior stamped value and early-returns, freezing the timestamp after the first stamp. Switch to `"dedicatedDateModified" in data` which correctly reads whether the key is present in the partial. Apply the same key-presence semantics to the meaningful-content check (body/title/summary) so both branches use a consistent reading of `data` as a partial. Add 8 unit tests covering create pass-through, first stamp, second stamp regression, editor override (value and explicit null), no-op on non-content field changes, and title/summary-only meaningful edits. Also refresh stale "FAQ rich-result eligibility" rationale comments in faq-page.ts and RelatedQuestionsBlock.tsx to "AI-search citation signal" framing (Google deprecated the FAQ rich result on 2026-05-07; the JSON-LD remains valuable to Perplexity, ChatGPT search, Gemini, and Google AI Overviews).

Findings: none.
R8 second pass. Done with the explicit prior "this contains at least one improvement." Considered: (a) idx as React key in RelatedQuestionsBlock / hostname row in KeyStatisticCallout, (b) redundant as const on "@type": "Question" as const when FaqPageSchema already narrows to literals, (c) the inline comment at [slug]/page.tsx:84 calling FAQPage the "SECOND top-level schema" when the array order puts it third (after Breadcrumb), (d) the hostnameOf fallback silently emitting malformed URLs as both link text and href, (e) duplicated length === 0 guard between RelatedQuestionsBlock and its PatternBody call site. All five are either R5 (bikeshed) or R7 (the URL-foot-gun is consistent with the project's existing handling of author-supplied URLs across realWorldExamples, references, etc. — flagging only here would be inconsistent). Nothing rises to SUGGESTION worth burning a slot on.
What this PR gets right (one specific note, not filler): the dedicatedDateModified hook uses 'key' in data rather than value-vs-originalDoc comparison — exactly the right semantics for Payload's partial-data shape on update, and the regression-named test at tests/unit/lib/hooks/before-change-dedicated-date-modified.test.ts:74 ("second stamp on subsequent body change... regression for partial-data bug") locks that fix in. The fix history (736c1a8) shows the prior bot review caught the value-comparison bug; this revision addresses it cleanly.
Same-tier risk: YES. Implementer was Opus, reviewer is Opus. Per R12 I applied extra skepticism on R8. Findings remain zero after that elevated bar.
Note on PR description accuracy (R5/non-blocking): the body claims pnpm test:unit — 549/549 pass and 537->549 (12 new tests). Actual is 545/545 (8 hook + 12 FAQ + others). Numbers don't match arithmetic; not a code defect, not blocking.

The prior commit added the dedicatedDateModified field to the Posts collection and regenerated payload-types.ts but did not generate the corresponding DB migration. CI provisions a fresh Postgres test_db and runs pnpm seed:test, which SELECTs posts.dedicated_date_modified against a schema that has no such column -- seeding aborts and all 4 E2E shards die with DrizzleQueryError. Generated via `pnpm payload migrate:create dedicated_date_modified`. Trimmed the auto-generated up()/down() body to only the truly new column -- the same diff also flagged media.lqip / media.preview_color / media.preview_ascii because the last reconciled JSON snapshot predates those migrations, but those columns already exist in prod and in any DB that has run the prior TS migrations. Re-adding them without IF NOT EXISTS would fail; trimming is correct because the prior migrations stand on their own. ALTER TABLE is idempotent (IF NOT EXISTS / IF EXISTS) per the project convention documented in migrations/README.md and N-1 safe: adding a nullable column does not break old container SELECTs. JSON snapshot is kept as-generated so it becomes the new state-of-truth for future migrate:create diffs. Addresses E2E failure on #397.

R8 second pass (mandatory, with the explicit prior "this contains at least one improvement"). Considered:
- The TOC gap above — the one that landed as a SUGGESTION.
- PR description claims
pnpm test:unit — 549/549 passand537 → 549 (12 new). Actual is 545/545 (likely double-counted the hook tests added in the fix commit). Description-only inaccuracy, R5 territory.

Same-tier risk: YES (implementer Opus → reviewer Opus). Per R12 I applied elevated skepticism on R8. One finding survived; the rest are bikeshed or pre-existing.
What this PR gets right (specific, not filler):
- The
dedicatedDateModifiedhook correctly uses'key' in datarather than value-vs-originalDoccomparison — Payload'sBeforeChangeHook.datais typedPartial<T>(verified innode_modules/.../payload/dist/index.bundled.d.ts:574), so key-presence is exactly the right semantics. The regression-named test atbefore-change-dedicated-date-modified.test.ts:74("second stamp on subsequent body change... regression for partial-data bug") locks the fix in. - The migration TS file correctly trims to only the new column despite the auto-generated diff also flagging
media.lqip/preview_color/preview_ascii; the docstring explains why (those columns already exist in any DB that ran the prior TS migrations) and the JSON snapshot resyncs as the new state-of-truth. - The visibility contract between
RelatedQuestionsBlockandgenerateFaqPageSchemais documented in both files and enforced by placing the renderer outside<DisclosureSection>— preventing the AI-search-penalty failure mode of JSON-LD that doesn't match rendered content.
Bottom line. Citation-bait infrastructure is correct and well-isolated. The single SUGGESTION (TOC links for newly-visible sections) is non-blocking; can ship as a follow-up before any pattern is populated with relatedQuestions.

SUGGESTION — This new visible Common questions section (and its sibling KeyStatisticCallout / ExpertQuoteBlock) is rendered with a scroll-mt-24 anchor (#common-questions), but PatternStickyRail.tsx's JUMP_LINKS array isn't extended to surface them in the "On this page" rail. When relatedQuestions is later populated for a pattern, readers won't be able to jump to it from the rail.
Suggested wiring (in PatternStickyRail.tsx, replacing the static JUMP_LINKS constant with a per-pattern computation):
const jumpLinks = [
...(pattern.keyStatistic ? [{ href: "#key-statistic", label: "Key stat" }] : []),
...(pattern.expertQuote ? [{ href: "#expert-quote", label: "Quote" }] : []),
{ href: "#decision-matrix", label: "Decision" },

{ href: "#implementation-sketch", label: "Sketch" },
{ href: "#references", label: "References" },
{ href: "#background-discussion", label: "Background ↓" },
];Non-blocking because all 23 patterns are unpopulated for these fields today — but worth wiring before Category I content population so a populated FAQ block doesn't ship without rail navigation.
