Battlescape victory summary screen "Intel found out that..."

[The Martian]

I continue to be impressed by the level of complexity found in the original X-Com, even after playing it for so long I keep discovering new interesting things.

While surfing the net I ran across a screenshot and noticed this line of text on the bottom of the battlescape victory summary screen:
"Intel found out that the Snakeman UFO was raiding North Africa"

This is the first time I've noticed this. (Probably because I've been spending the majority of my time in the "New Battle - Mission Generator" instead of playing a proper campaign.)

I have some questions about the game's rules surrounding this line of text:
(1) What causes it to be generated?
(2) What is the range of information this section can display?
(3) What modding options exist to effect this text?

This is not OpenXcom functionality.

It's from UFOExtender: https://www.ufopaedia.org/index.php/UFOextender#Wreck_Analysis

Which UFOExtender features are activated by default in OXCE 6.7.2?

I'm curious about "know thy enemy".

Which UFOExtender features are activated by default in OXCE 6.7.2?

Same as in OXC.
I didn't (knowingly) add any UFOExtender features in OXCE. And if I did by coincidence, they'd be turned off by default.
