When the stack builder picks it
The builder reads each job's rules from the top and takes the first step whose conditions hold and whose plan fits the money left. Quadratic is named in these steps:
- Spreadsheets and data, step 2 of 3, when less than $8 is left for it: the free plan; the step also names Rows and Julius AI, and the best score takes it.
- Spreadsheets and data, step 3 of 3, otherwise: Pro ($18/mo billed yearly only ($216 a year)); the step also names Rows and Julius AI, and the best score takes it.
The rules are public in stack-rules.json, and how the stack builder scores explains the tie-break.
