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. ChatGPT is named in these steps:
- Copywriting, step 3 of 4, when less than $20 is left for it: the free plan; the step also names Gemini and Claude, and the best score takes it.
- Copywriting, step 4 of 4, otherwise: Plus ($20/mo); the step also names Claude and Gemini, and the best score takes it.
- Email marketing, step 3 of 3, otherwise: the free plan; the step also names Claude and Gemini, and the best score takes it.
The rules are public in stack-rules.json, and how the stack builder scores explains the tie-break.
