They start somewhere in this general area:
https://elixir.bootlin.com/linux/latest/source/include/linux/audit.h#L330
There are many hooks. The auxiliary record types are in the 1300 block:
https://elixir.bootlin.com/linux/latest/source/include/uapi/linux/audit.h#L89
The one exception is AUDIT_REPLACE which was mistakenly placed in this block.
It should have been in the 1000 block.
