# Codebase Context for Investigation
## Project Structure
- **app/** - Phoenix LiveView application with blogs, user auth, editor dashboard
- **blogex/** - Multi-blog engine library (Blogex) with NimblePublisher-based markdown posts
## Key Modules
### Blog Config (app/lib/firehose/blogs/)
- `Firehose.EngineeringBlog` - blog_id: :engineering, base_path: "/blog/engineering"
- `Firehose.ReleaseNotes` - blog_id: :release_notes, base_path: "/blog/releases"
### Blog Post System (blogex/lib/blogex/)
- `Blogex.Post` - struct with fields: id, title, author, body, description, date, blog, image, tags, published
- `Post.visibility(post)` returns :draft (published=false), :scheduled (future date), :live
- `Post.days_until_live(post)` returns days until scheduled post goes live
- Posts are compiled at build-time from markdown files in priv/blog/
### Blog Module (blogex/lib/blogex/blog.ex)
- `Blogex.Blog` - macro that uses NimblePublisher
- `all_posts()` - returns published, non-future-dated posts (drafts excluded in prod)
- `unfiltered_posts()` - returns ALL posts including drafts and future-dated
- `recent_posts(n)` - returns n most recent published posts
- `paginate(page, per_page)` - pagination support
### Registry (blogex/lib/blogex/registry.ex)
- `Blogex.Registry.all_posts()` - all published posts across blogs
- `Blogex.Registry.all_posts_unfiltered()` - all posts including drafts/scheduled
- `Blogex.Registry.get_blog!(blog_id)` - get blog module by atom
### Router (app/lib/firehose_web/router.ex)
- GET / - PageController.home (homepage with recent posts)
- GET /blog/:blog_id - BlogController.index (blog listing)
- GET /blog/:blog_id/:slug - BlogController.show (single post)
- GET /blog/:blog_id/tag/:tag - BlogController.tag (posts by tag)
- GET /api/blog/engineering - Blogex.Router (serves HTML+JSON+RSS)
- GET /api/blog/releases - Blogex.Router (serves HTML+JSON+RSS)
- LiveView: GET /editor/dashboard - EditorDashboardLive (authenticated)
- LiveView: GET /microprints - MicroprintsLive
### Blogex Router (blogex/lib/blogex/router.ex)
- Serves at /api/blog/{engineering,releases}
- GET /feed.xml - RSS 2.0 feed
- GET /atom.xml - Atom feed
- These are mounted under /api/blog/* so feeds are at /api/blog/engineering/feed.xml
### Blog Controller (app/lib/firehose_web/controllers/blog_controller.ex)
- Renders blog index, show, and tag pages using Phoenix templates with Blogex.Components
- Uses the Phoenix layout (app.html.heex) with full UI
### Editor Dashboard (app/lib/firehose_web/live/editor_dashboard_live.ex)
- Authenticated LiveView at /editor/dashboard
- Shows Drafts and Scheduled posts tabs
- Uses Blogex.Registry.all_posts_unfiltered()
- Has a tab switcher between drafts and scheduled
- Each post shows title, author, date, status
### Layout/UI (app/lib/firehose_web/components/layouts/app.html.heex)
- Navbar with links to: Home, Blog, Releases, QWAN (external), Contact, theme toggle
- No RSS icon/link visible in nav
- No link to Editor Dashboard in nav (only accessible via direct URL)
### Homepage (app/lib/firehose_web/controllers/page_html/home.html.heex)
- Shows intro text and recent posts grid (6 most recent across both blogs)
### Email/Mailer
