I've been working with the Magento Firegento custom Composer installer, and I ran into this odd bit of Composer behavior I don't understand.

Consider the following dead simple composer.json file

{
    "require": {
        "magento-hackathon/magento-composer-installer": "*"
    }
}

If I run compser.phar install with this composer.json file, I get the following.

$ composer.phar install --no-dev 
Loading composer repositories with package information
Installing dependencies
  - Installing aoepeople/composer-installers (v0.0.1)
    Loading from cache

Writing lock file
Generating autoload files

From my mostly lay-person's understanding composer.phar, I've said

Hey, composer, please install the magento-hackathon/magento-composer-installer package from packagist.org

And composer has said back to me

Sir, yes sir! Here's the aoepeople/composer-installers package

I don't understand why composer installed aoepeople/composer-installers, when I asked for magento-hackathon/magento-composer-installer.

To be clear: I understand the reason magento-hackathon/magento-composer-installer wasn't installed is this is a package that lives in a different composer repository. My original mistake was not including this repository in my composer.json file.

However, it doesn't make sense to me that composer would install a different package than the one I asked for. When I search packagist there's no magento-hackathon/magento-composer-installer extension.

Why does packagist install a different extension? What's happening behind the scenes to make magento-hackathon/magento-composer-installer resolve to aoepeople/composer-installers? How/where in the composer source could I debug this sort of thing myself in the future?
