How complete GH Archive is

The question

How complete have GH Archive's hourly files been since September 2026?

What the record says

All 452 sampled GH Archive files were present and nonempty, but pushes, creates and deletes were jointly absent from 90 of 272 September–November panel files, including runs before 15 October. The September baseline failed the brief's test, so the before-and-after comparison is descriptive.
