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. Perplexity is named in these steps:
- Research, step 2 of 3, when less than $20 is left for it: the free plan; the step also names Gemini Notebook (NotebookLM), Consensus and Elicit, and the best score takes it.
- Research, step 3 of 3, otherwise: Pro ($17/mo billed yearly); the step also names Consensus, Elicit, Scite and Gemini Notebook (NotebookLM), and the best score takes it.
The rules are public in stack-rules.json, and how the stack builder scores explains the tie-break.
