The Monorepo
A four-package monorepo: 4,127 files, roughly 2.9 million tokens of source. A customer who switched from monthly to annual was invoiced $5,760 for a $480 plan, and one test in packages/billing is red because of it. Your window holds 200,000 tokens. The repository does not fit in it and never will. Find the line, change it, and prove it — with window left.
Nothing here calls a model or touches a repo. The scenario is a state machine, so the same sequence of instructions always ends in the same place — which is what makes the feedback afterwards a fact rather than an opinion. You start 5,280 tokens down before typing a word; that is what a real session costs at launch.
