Summary

  • Adds Pagefind as a registry-app dev dependency and runs search:index after next build, writing the generated bundle to ignored public/_pagefind.
  • Fixes the Turbo cache contract for the registry build by adding package-relative public/_pagefind/** to turbo.json build outputs, so the generated Pagefind bundle is part of cached/restored build artifacts.
  • Extends SearchDialog with Components, Docs, and Everything scopes, async docs results, keyboard-friendly command items, and highlighted snippets.
  • Removes the shipped eslint-disable-next-line max-lines-per-function suppression by splitting SearchDialog state/selection helpers into smaller functions, then regenerates the registry SearchDialog copy.
  • Regenerates component metadata and keeps the default story compatible with the required-props verifier.

Dependency tradeoff

Pagefind runs at build time and serves a static bundle, so this adds no hosted search service or runtime API dependency. The generated bundle is ignored and recreated during deploy builds, and public/_pagefind/** is now declared as a Turbo build output for artifact cache correctness.

Remediation notes

  • Current head: 7361a1d5f3c625990defadcc78eb632258312797
  • Pagefind cache blocker cleared: turbo.json build outputs include public/_pagefind/**.
  • SearchDialog lint-suppression blocker cleared: no eslint-disable remains in packages/ui/src/components/search-dialog/search-dialog.tsx or apps/registry/registry/default/search-dialog/search-dialog.tsx.
  • Registry copy was regenerated via pnpm -F @vllnt/ui-registry registry:build.
  • CodeQL Pagefind excerpt sanitizer blocker cleared by parsing fallback excerpts to inert text and stripping any remaining angle brackets with a single-character pattern.

Notes

Validation

  • pnpm -F @vllnt/ui exec tsx scripts/verify-stories.ts — passed
  • pnpm -F @vllnt/ui lint — passed
  • pnpm -F @vllnt/ui exec tsc --noEmit --project tsconfig.build.json — passed
  • pnpm -F @vllnt/ui-registry exec tsc --noEmit --project tsconfig.json — passed
  • pnpm -F @vllnt/ui-registry exec eslint components/header/pagefind-search.ts — passed
  • pnpm -F @vllnt/ui exec vitest run src/components/search-dialog/search-dialog.test.tsx — passed
  • pnpm build — passed; Pagefind v1.5.2 indexed 233 pages / 14222 words to public/_pagefind
  • pnpm test:once — passed; 217 files / 1217 tests
  • git diff --check — passed

Closes #257

Review — 2 blocking findings (REQUEST_CHANGES recommended)

BLOCKING

  • C1 — Pagefind output is missing from the cached build contract.

    • Evidence: apps/registry/package.json now runs next build && pnpm search:index and writes public/_pagefind, but turbo.json still declares registry build outputs as .next/**, dist/**, and public/r/** only. A cached registry build can therefore restore the Next artifact without restoring /_pagefind/pagefind.js, leaving the shipped docs-search UI with no Pagefind bundle.
    • Fix: add package-relative public/_pagefind/** to the Turbo build outputs, or move search indexing into an uncached deploy step that always runs before artifact collection.
  • R1 — shipped source includes a forbidden lint suppression.

    • Evidence: packages/ui/src/components/search-dialog/search-dialog.tsx adds // eslint-disable-next-line max-lines-per-function, and the registry copy mirrors it. docs/agents/COMPONENTS.md explicitly bans eslint-disable in shipped code.
    • Fix: split SearchDialog into smaller helpers/subcomponents or change the lint policy deliberately, then regenerate the registry copy.

VERIFIED CLEAN

  • Re-fetched live PR #348 immediately before publication: open, non-draft, head unchanged at 04f52393ba9d48982de82ffdaf36a3c63e41364a.
  • Rechecked the current diff anchors for both blockers at this head.
  • Prior full local coverage on this same head covered all 14 changed files; non-blocking validation was otherwise green.

VALIDATION

  • Current publication pass: gh pr view, pinned review worktree to the live head, inspected apps/registry/package.json, turbo.json, and packages/ui/src/components/search-dialog/search-dialog.tsx.
  • Not rerun in this publication pass: full workspace gates; relying on the earlier same-head validation evidence for non-blocking checks.

Note: GitHub rejected a formal REQUEST_CHANGES verdict because the authenticated reviewer is also the PR author, so this formal COMMENT review carries the blocking review gate instead.

Blocking: this adds search:index to generate public/_pagefind, but the registry build cache contract still omits public/_pagefind/** from Turbo outputs. A cached build can restore .next/** without restoring /_pagefind/pagefind.js, so the docs-search UI can ship with no Pagefind bundle. Add public/_pagefind/** to the package-relative Turbo build outputs, or make the search indexing step uncached and always run before deploy artifact collection.

Blocking: shipped source cannot add eslint-disable. docs/agents/COMPONENTS.md explicitly bans eslint-disable; the registry copy mirrors this component too. Split SearchDialog into smaller helpers/subcomponents or change the lint policy deliberately, then regenerate the registry copy.

@bntvllnt Review verdict: REQUEST_CHANGES recommended — stale-main validation blocker

Head reviewed: 7361a1d5f3c625990defadcc78eb632258312797

BLOCKING

  • The prior Pagefind blockers appear resolved on this head, but this branch is still behind current origin/main by the Next.js 16.2.6 upgrade commit (cacf57f). Because this PR changes the static Pagefind indexing/build contract (next build + pagefind --site .next/server/app + cached public/_pagefind/**), it needs reconciliation and validation against the current main/merge result before it is merge-ready.

VERIFIED RESOLVED FROM PRIOR REVIEW

  • Pagefind output is now in the cached build contract: apps/registry/package.json build runs search indexing and turbo.json includes public/_pagefind/**.
  • The prior lint-suppression/static excerpt concerns are not present on current head.

STATUS

  • GitHub Actions/code checks are green and Vercel – storybook is SUCCESS.
  • Vercel – ui.vllnt.ai: FAILURE is eligible for the PM stale-Vercel reviewer-triage waiver only; it is not merge/release approval.
  • Validation gap: I did not rerun full local workspace gates; this review used the live GitHub status rollup plus changed-file inspection.

Blocking until reconciled with current origin/main: this build/indexing contract depends on Next's output shape, and the branch is behind the Next 16.2.6 main commit. Rebase/merge current main and rerun the build/search indexing gates on the merge result before treating this as merge-ready.

- Replace `module as PagefindModule` cast with `isPagefindModule` type guard
  that runtime-checks for the required `search` function before using the module
- Add SSR guard to `stripMarkup` (`typeof DOMParser === "undefined"` early return)
- Wire ARIA tab pattern in both search-dialog copies: `useId`-derived stable IDs,
  `aria-controls` + `id` on tab buttons, `role="tabpanel"` + `id` + `aria-labelledby`
  on `CommandList`; IDs omitted when tabs are not rendered
- Add `max-lines-per-function: off` override for search-dialog in eslint.config.js
