Module 2 — Platform

Selection and Priority Ranks

File: modules/module2.py

Module 2 records, for each of the 12 built-in platforms (plus any custom platforms defined in core/kpi_config.py), whether it's selected and, within the active objectives, its priority 1 and optional priority 2. The priority structure drives system goal weights when no goal values are set in Module 1.

Platform codes

Code	Display
fb	Facebook
ig	Instagram
li	LinkedIn
yt	YouTube
tt	TikTok
pt	Pinterest
tw	X (Twitter) — code kept tw for back-compat
sn	Snapchat
rd	Reddit
go_search	Google Search
go_display	Google Display Network
go_pmax	Google Performance Max

Why Google is three platforms

Search, Display, and PMax have lead-gen productivities that differ by an order of magnitude. Conflating them into one "Google" entry would hide the most important channel decision a marketer using this tool needs to make — so they're kept distinct.

Active platforms vs selected

active_platforms is the set of selected platforms that have at least one priority slot filled. This is the list Module 3 onward iterates over. A platform "selected but unprioritised" surfaces a validation error rather than being silently ignored — explicit beats implicit.
