Blog articles not appearing in production

[mockdeep]

I'm having some trouble getting my blog to build for production. Everything renders fine in dev mode, but when I run middleman build it generates index.html as if there were no articles. What am I doing wrong? Here's the file structure I have:

source/
|-- articles
|   `-- 2014-09-19-first-post.html.markdown
|-- calendar.html.erb
|-- feed.xml.builder
|-- images
|-- index.html.erb
|-- javascripts
|-- layout.html.erb
|-- layouts
|   `-- article_layout.html.erb
|-- partials
|   |-- _footer.html.erb
|   `-- _nav.html.erb
|-- stylesheets
|   |-- all.css.scss
|   |-- base
|   |   |-- _base.scss
|   |   |-- _buttons.scss
|   |   |-- extends
|   |   |   |-- _button.scss
|   |   |   |-- _clearfix.scss
|   |   |   `-- _hide-text.scss
|   |   |-- _flashes.scss
|   |   |-- _forms.scss
|   |   |-- _grid-settings.scss
|   |   |-- _lists.scss
|   |   |-- mixins
|   |   |   `-- _flash.scss
|   |   |-- _tables.scss
|   |   |-- _typography.scss
|   |   `-- _variables.scss
|   |-- partials
|   |   |-- _article.css.scss
|   |   |-- _footer.css.scss
|   |   |-- _layout.css.scss
|   |   `-- _nav.css.scss
|   `-- syntax_highlighting.css.erb
`-- tag.html.erb

and my configuration:

activate :blog do |blog|
  blog.sources = 'articles/{year}-{month}-{day}-{title}.html'
  blog.tag_template = 'tag.html'
  blog.calendar_template = 'calendar.html'
end

activate :syntax, line_numbers: true
set :markdown_engine, :redcarpet
set :markdown, fenced_code_blocks: true,
               smartypants: true,
               space_after_headers: true,
               no_intra_emphasis: true,
               tables: true,
               autolink: true,
               disable_indented_code_blocks: true,
               strikethrough: true,
               lax_spacing: true,
               superscript: true,
               underline: true,
               highlight: true,
               quote: true

page '/feed.xml', layout: false

page '/articles/*', layout: :article_layout

set :css_dir, 'stylesheets'
set :js_dir, 'javascripts'
set :images_dir, 'images'
set :build_dir, 'tmp'

configure :build do
end

configure :development do
  activate :livereload
end

and the output from a clean middleman build --verbose:
