Great work!
I'm that anon.
It means when they chose that password for the trip change - and I don't remember how long ago this last one was off the top of my head - they had that date in mind. The 23'rd.
It means they've been planning something for this day since at least their last trip change. (I suspect they've been planning for this day for a long, long time)
To us, it's a way of establishing they had foreknowledge of it.
So of course they'd 'oops' the password into the open, because it wouldn't serve much purpose past the 23'rd.
Pleasantly surprised.
About 4 days and enormous amounts of popcorn lad.
The deep state fired prematurely.
