Closes #142

What

  • posts collection (data/blog/*.mdx): title, href, excerpt, publishedAt, optional updatedAt and tags, and status: draft | published. Each post gets a computed reading time.
  • /blog index, built from the homepage Panel components: title, excerpt, date, reading time, tags, newest first. It says "Nothing published yet." when empty.
  • /blog/[slug], modelled on the project case-study page: article OG metadata, Twitter card, canonical URL, and highlight-to-ask enabled. Inline code is styled without the prose backticks.
  • Blog nav entry using the previously unused Icons.blog. It's the first nav item that points at a real route instead of a homepage anchor, which is a deliberate deviation. Real routes are marked active by pathname; anchors keep scroll-spy.
  • Sitemap gets /blog plus each visible post.
  • Drafts only render in pnpm dev, with a Draft badge. Production never lists, prerenders or maps them, and their URLs return 404. All of this is decided in one filter in lib/blog.ts.

Posts (all status: draft)

Each has its own review issue:

Before merge

  • Flip at least one post to status: published, otherwise production /blog shows the empty state.
  • Work through the "check this" list in each post's issue.

Verification

  • pnpm lint: 0 errors. The only warnings are pre-existing, plus the same generated-file warning allProjects/allWorks already get.
  • pnpm build passes.
  • In a production build with one published and one draft test post, only the published one is prerendered, and the draft returns 404.
  • In dev, /blog and all six post routes return 200.

Summary by CodeRabbit

  • New Features
    • Added a blog with searchable, paginated post listings, individual articles, publication dates, reading times, and draft indicators.
    • Added Blog to site navigation and featured recent posts on the homepage.
    • Added article tools for copying or viewing Markdown, sharing posts, and navigating between articles.
    • Added Markdown versions of posts and a plain-text feed of blog information.
    • Enabled highlight-to-ask on blog posts and included them in the sitemap.

Update: nav, background, chatbot

  • Navbar: Blog is no longer in the navbar. Posts are reached through the homepage "Blog" section (latest 3 plus "All posts") and /blog. The nav-icon and real-route active-state code that only existed for the Blog item is reverted.
  • Background name: the big background page name is hidden on /blog/<slug>, since sentence-length slugs at 200px read as noise. /blog still shows "Blog".
  • Chatbot context:
    • Blog routes now send their slug as page context.
    • On a post page, the post's full Markdown goes into the chat context, so the bot answers from the text.
    • Every published post is listed in the context, so it can point to posts from anywhere on the site.
    • Tested against a production build: asked about "the gotcha with the cleanup workflow" on the Dukkani post, it answered correctly from the post. Asked "any posts about rate limiting?" from the homepage, it linked /blog/rate-limiting-orpc.
  • Main merged in: the only conflict was in app/page.tsx (the repo-info refactor from Show open-source contributions (Databuddy, Zed) #159 plus the latest-posts data).

Add a posts content collection (data/blog/*.mdx) with draft/published
status, a /blog index and /blog/[slug] article pages with OG metadata
and reading time, a Blog nav entry linking to the real /blog route,
highlight-to-ask on posts, and sitemap entries. Drafts only render in
development.
Six drafts, all status: draft until reviewed: per-PR environments in
Dukkani, batching ClickHouse queries in Databuddy, dotfiles and agent
rules, rate limiting an oRPC API, the Sonaraem Spotify allowlist
rotation, and function regions on Vercel.

Merge Risk: ⚪ Minimal · up to 51d10

The blog has published content, and its Markdown URLs match the configured routes. No concrete merge-blocking issue remains; merge after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 51d10

The inspected publication paths consistently exclude drafts outside development, and request slugs only select existing visible posts. Blog excerpts reuse the existing chat flow without adding permissions or credentials. Production delivery and excluded image contents remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — An error in the shared visibility policy could affect multiple publication surfaces, but inspected consumers consistently apply it. Public callers select visible repository records; no tenant, protected data-store, or infrastructure authority expansion was identified in these paths.

Trust Boundaries and Controls

  • observed — Blog selection enters the existing chat path as quoted user-message text. Clicking Ask seeds a draft rather than sending it automatically; submission reaches the existing model endpoint. Base-to-head inspection shows no changes to that endpoint, tool declarations, or credentials. Quote formatting is not an enforced prompt-trust boundary, but no new privileged execution path was established.

Resilience and Maintainability Implications

  • observed — Ask clears the current selection, but cleanup is not keyed to article pathname, and chat drafts persist across navigation. These behaviors already existed for case studies. Blog routes also lack a matching page-context description. The inspected state remains visitor-controlled and requires submission; no cross-user ownership or authorization failure was established.

Hardening Proposals

  • proposed — Bind selected excerpts to their originating article, clear pending selection on pathname changes, and supply accurate blog context. Keep excerpt content distinct from the visitor’s instructions when constructing model input. These are provenance and trust-boundary improvements, not verified vulnerabilities introduced by this PR.

Explanation

The pull request adds public interfaces and site features that #142 does not request. These include /llms.txt, per-post Markdown routes and rewrites, and a homepage latest-posts panel. The searchable infinite-loading index and post toolbar also add behavior beyond the issue's required list-and-read routes. These changes are related to blog content in part, but the new /llms.txt interface has no stated connection to the blog-section requirements.
