Home Province Immune to Slave Labor?

YES, that event works.

NO, it's not that great, but can be useful.

It works the same way as the invisible "rollover" resources present from the previous turn.

For example, say a province produces 15 resources each turn; this is reported each turn in the recruitment screen.
-Turn 1: you queue up 3 Light Infantry at 10 resources each; consequently, in the queue, 1 Light Infantry is bright and 2 are dark.
-Turn 2: you now have 1 Light Infantry in the garrison, and 2 still in the queue; as in turn 1, only 1 of the Light Infantry is bright.
-Turn 3: you now have 3 Light Infantry in the garrison, and zero in the queue, despite the fact that the queue contained only 1 bright unit. This is due to a hidden "bank" of 5 resources that rolled over from turn 1.

The Slave Labor event works in the exact same way. It adds a random number of resources to that hidden bank.

This number is small (probably hasn't changed from dom2). I'd guess a DRN. BUT, if you're massing chaff, like the slingers I was massing when I figured it out, it can be a pleasant surprise. I think I got like 20 more than I expected.
