First session
Every new player gets one intro track. Each row follows the people who got that track through the teaser: each stage column counts who quit THERE (furthest point reached, columns sum to "got"). The columns that matter: played = went on to finish a real game, reg = created an account.
Cohort. Last 21 days, organic default intro setup only (the numbered 365scores setups are excluded - their audience quits regardless of track, which would smear the comparison). People are stitched identities; internal + QA traffic excluded. Stages. quit L1 = closed during the first stem layer; L2/L3 = quit after reaching that layer; guess = opened the guess box but never answered; wrong / right = final guess outcome, then left; finish = completed the full teaser flow (this event under-fires in the current build - fix queued - so read "played" as the real outcome). played = completed at least one real game after the intro (server records, not client events). Dimmed rows have under 10 people - read direction, not decimals. Web rows are weak for every track: that is the channel, not the song.
