Suggestion: This post is marked as published, but it is stored under content/blog-post-2026-06-30/ while the content pipeline only ingests content/blog/**/*.mdx (velite.config.ts). As a result, the article will never be built, listed, or routed in the blog. Move the file into content/blog/ (or expand the collection pattern) so published posts are actually discoverable. [api mismatch]

Severity Level: Major ⚠️
- ❌ Velite posts collection omits this published article entirely.
- ⚠️ Blog-related UIs consuming posts data miss this article.
Steps of Reproduction ✅
1. Open the content pipeline configuration at
`/workspace/frontend-junction/velite.config.ts`, where the `posts` collection is defined
at lines 11–14 with `pattern: 'blog/**/*.mdx'` and the root content directory is set at
lines 30–31 as `root: 'content'`.

2. Inspect the new blog post file at
`/workspace/frontend-junction/content/blog-post-2026-06-30/next-js-app-router-in-2026-a-practical-guide.mdx`
and note the frontmatter `published: true` at line 6 in the PR hunk, while the file
resides under `content/blog-post-2026-06-30/` instead of `content/blog/`.

3. Run the Velite content generation using this configuration (the `posts` collection
defined in `velite.config.ts:11–28` will scan only files matching
`content/blog/**/*.mdx`), and observe that files under `content/blog-post-2026-06-30/` do
not match the configured pattern.

4. Inspect the generated data under the configured output directory `.velite` (see
`velite.config.ts:32–34`) or any consumer of the `posts` collection; the article
`next-js-app-router-in-2026-a-practical-guide.mdx` will not appear in the posts data
despite being marked `published: true`.

Suggestion: The frontmatter references ./images/post-image.png, but there is no such file in the repository under this post path (or elsewhere in content). This creates a broken asset reference and can fail image processing when the post is ingested. Point image to an existing file or add the missing image asset. [api mismatch]

Severity Level: Major ⚠️
- ⚠️ Velite image resolution fails or logs error for post.
- ⚠️ Blog UI displays broken or missing thumbnail for article.
Steps of Reproduction ✅
1. Open the blog post file at
`/workspace/frontend-junction/content/blog-post-2026-06-30/next-js-app-router-in-2026-a-practical-guide.mdx`
and inspect the frontmatter line 7, which sets `image: './images/post-image.png'`.

2. Search the repository for the referenced asset path by globbing `**/post-image.png`
under `/workspace/frontend-junction`; the Glob tool returns no matches, confirming that
`post-image.png` does not exist anywhere in the project (including under
`content/blog/images`).

3. Review the Velite schema in `/workspace/frontend-junction/velite.config.ts` at lines
22–23, where `image: s.image().optional()` is declared in the `posts` collection,
indicating that the pipeline expects a valid image asset path relative to the `content`
root when an `image` frontmatter field is provided.

4. When the content pipeline ingests this post and attempts to resolve
`./images/post-image.png`, the missing file will cause the image resolution step either to
fail (depending on Velite’s behavior for nonexistent assets) or to produce a broken image
reference in any UI that renders the post using the `image` field.

10-82: 📐 Maintainability & Code Quality | 🟠 Major | 🏗️ Heavy lift

Major: Content doesn't match title — no actual Next.js App Router patterns covered.

The post promises a "Practical Guide" to "Next.js App Router" but contains zero Next.js-specific code or concepts. The TypeScript examples (Lines 24–34, 53–71) are generic React with no App Router APIs — no Server Components, loading.tsx, error.tsx, data fetching, caching, or routing patterns. Readers expecting actionable Next.js guidance will find only generic advice ("measure before optimizing", "start simple"). Either retitle as a general frontend guide, or rewrite with actual App Router patterns.

🎯 Functional Correctness | 🔴 Critical | ⚖️ Poor tradeoff

Critical: Blog post path will not be picked up by Velite.

The file is located at content/blog-post-2026-06-30/... but velite.config.ts defines the posts collection with pattern: 'blog/**/*.mdx'. Velite will only match files under content/blog/, so this post will be silently ignored and never rendered. Move the file to content/blog/2026-06-30-next-js-app-router-in-2026-a-practical-guide.mdx (or similar path under content/blog/).
