Threshold bench
Toggle absolute and relative gates; watch which exceptions survive for a Gyeongsangnam-do calendar close.
Variance Lab
Budgeting variance audits, rehearsed
Sample entities, real queue pressure, no production risk.
A thematic workspace for practicing how a financial auditing app should surface budgeting variance audits—before your live close.
What you practice here
Three fictional Korean entities ship with deliberately messy mappings: a Busan manufacturer, a Seoul retail holdco, and a logistics desk with freight that refuses to stay coded.
You apply thresholds, tag root causes, and write board comments against exports that look like the ones your tool produces on Monday.
Lab stations
Taxonomy wall
Drag unexplained lines into volume, rate, mix, timing, or data-quality buckets—then defend the choice.
Narrative desk
Draft comments that cite the app’s evidence IDs so controllers never retype your work.
Pair the Lab with a cohort seat
