pam_heresy_c1_resolve_differences_effect

The comment above it in the file

Faith scope (called after change_rite_divergence has been applied).
Saves scope:differing_tenet / scope:differing_doctrine for the C1 flavour text.
C1 narrates a within-rite shift, so the comparison must be against the pre-divergence snapshot of scope:diverging_rite - not against the parent faith's main rite (which would surface pre-existing differences like Mozarabic's Communion).
C2/C3 keep using rite_growth_resolve_differences_effect because there the mainline-vs-new-rite delta is the relevant story.

What it does

• 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.
