Workshop Attendee Analytics

Utilities for cleaning, comparing, and organizing repeated workshop attendance lists.

Capabilities

Produce unique attendee roster

• ["kim","kim","lee","kim","park"] yields ["kim","lee","park"], preserving first-seen order. @test

Shared attendees between sessions

• ["ash","bo","cato","dee","ash"] and ["cato","ash","em"] produce ["ash","cato"], ordered by first session appearance. @test

Count attendees by team

• Records [ {id:"a",team:"red"}, {id:"b",team:"red"}, {id:"c",team:"blue"}, {id:"d",team:"red"} ] return {red:3, blue:1}. @test

Group attendees by role

• Records [ {id:"1",role:"mentor"}, {id:"1",role:"mentor"}, {id:"2",role:"learner"}, {id:"3",role:"learner"} ] yield {mentor:["1"], learner:["2","3"]} with role buckets preserving first-seen order per id. @test
