is_movement_in_power

The comment above it in the file

To determine if situation_participant_group is favored
Use e.g. "MOVEMENT = expansion_movement" to check a specific movement

What it checks

• the game's own tooltip text · ◦ our reading of the script line · code the script where neither exists

“They” is whatever it runs on (the scope it is called in). The scripted triggers and effects it calls link to their own pages; $PARAMETERS$ stay as written: each call fills them in.
