D'oh! Had an error in my URL, so it wasn't processing. When I manually ran archive.php through the command line, everything came up in the interface except for the page titles and page URLs. (See screenshots.)
The site is fairly high traffic -- there's usually a visitor every 2-3 minutes throughout the day -- but I'm not sure why the page URLs aren't showing up.
Edited to add: When I expand the date range to a few days, only one page title and URL show up... the other six hits are "page url not defined." When I debug the tracking API request using Firebug, piwik.php doesn't show up in the NET panel, but if I hit shift-refresh, only piwik.js shows.
