 For every single source route in a phase, we check to see whether the route is a match, and process the relevant details (for more details on source checking see the [Checking Source Routes section](#checking-source-routes)). When we receive a response from the route checker, if we encountered an error — normally from running middleware — we break out of the routing process and return the error response. Otherwise, the only other time we disable the continuation of routing is if the route checker returns a final match.

 If the current phase is `miss`, we check the build output, if there is no file matching the requested one we set the status code to 404. Afterwards, if a file was found in the output, or the current phase is `error`, we move on to the `hit` phase. It is important that the `hit` phase is run every time a match is found in the build output or when the current phase is `miss` or `error`, because this allows us to update the headers for the response with the current matched path.
