This published MDX file sits under content/blog-post-2026-07-14/, while the site loads blog posts from content/blog/**/*.mdx. The content loader will skip this post, so it will not appear in the generated post list or static blog routes, and visitors will hit a 404 for the intended article.

Suggestion: This post is placed under content/blog-post-2026-07-14/, but the content pipeline only indexes content/blog/**/*.mdx (velite.config.ts pattern). As a result, this article will never be built into #site/content, so it won’t appear on the blog page, RSS, sitemap, or post routes. Move the file under content/blog/ (or update the collection pattern to include this folder) so it is actually published. [api mismatch]
Severity Level: Critical 🚨
❌ New article invisible on /blog listing page.
❌ New article missing from individual post routes.
❌ New article absent from homepage latest posts.
❌ New article excluded from RSS feed.xml output.
❌ New article missing from sitemap blog URL list.
⚠️ Tags page omits tags from this new article.Steps of Reproduction ✅
1. Open `velite.config.ts` at `/workspace/frontend-junction/velite.config.ts` and observe
the posts collection definition: line 11 `const posts = defineCollection({` and line 13
`pattern: 'blog/**/*.mdx',` with line 31 `root: 'content'`, meaning only files under
`content/blog/**/*.mdx` are indexed into `#site/content`.
2. Note the new article file path
`/workspace/frontend-junction/content/blog-post-2026-07-14/typescript-patterns-in-2026-a-practical-guide.mdx`
(confirmed via `LS`), which lives under `content/blog-post-2026-07-14/` instead of
`content/blog/`, so it does not match the `blog/**/*.mdx` pattern.
3. Start the Next.js app (e.g., `npm run dev` or `npm run build && npm start`) so Velite
generates `#site/content` from the configured collection; then open `/app/blog/page.tsx`
(lines 1–8) where `posts` is imported from `'#site/content'` and used at line 30 `const
sortedPosts = sortPosts(posts.filter((post) => post.published));` to render the blog
index.
4. Visit `http://localhost:3000/blog` while the app is running and observe that the
“TypeScript patterns in 2026: A Practical Guide” post (from the MDX file with `published:
true` at line 6) does not appear in the list, because it was never included in `posts` due
to the directory mismatch.
5. Visit `http://localhost:3000/` (home page) and see that `getLatestPosts()` in
`/app/page.tsx` (lines 94–107) uses the same `posts` array from `'#site/content'`, so the
new article is also missing from the homepage “latest posts” section.
6. Visit `http://localhost:3000/feed.xml` and `http://localhost:3000/sitemap.xml` where
`/app/feed.xml/route.ts` (lines 1–17) and `/app/sitemap.ts` (lines 37–47) iterate over
`posts` from `'#site/content'`; confirm the new article has no RSS entry and no sitemap
URL, reproducing the bug that content under `content/blog-post-2026-07-14/` is effectively
unpublished.

Correct grammatical and capitalization errors.
The phrasing appears to be generated from a template, leading to subject-verb agreement issues (e.g., "patterns continues", "patterns Matters") and incorrect capitalization of "TypeScript".

"TypeScript patterns is" creates a subject-verb agreement mismatch. Rephrasing it slightly fixes the flow.
