Missing projects in the API

I did a random check to see if any projects were missing, as the total number of projects seemed a bit low to me. Here are the projects I could find so far whose issues we should be getting, but which are not visible in the API:

No files, tests, or entry points are named. Start by comparing the API's project and issue results with the linked GitHub searches, focusing on the remaining unchecked cases and their notes. Done means the cause of each omission is identified and eligible projects or issues appear in the API, with genuine age or listing exclusions accounted for.
