Where the rules name 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. Moises is named in these steps:
- Stem separation, step 3 of 4, when less than $6 is left for it: the free plan; the step also names Fadr and LALAL.AI, and the best score takes it.
- Stem separation, step 4 of 4, otherwise: Premium ($5.99/mo); the step also names LALAL.AI, Fadr and AudioShake Indie, and the best score takes it.
The rules are public in stack-rules.json, and how the stack builder scores explains the tie-break.
Alternatives the same rules name
