Screen up to 5 Promise Gap slugs in one call — tier matrix + machine briefs. Pay $0.45 vs 5×$0.12 singles. Indicative — Gap ≠ fraud; Gap ≠ Activity ≠ Variance. Task: Call when an agent must screen a shortlist of energy/RWA names before deep desk work or inclusion. Why pay: $0.45 ≪ five separate Gap calls and ≪ allocating into a loud-claim / thin-activity name that a batch screen would have flagged.
Machine Promise Gap pack — claim intensity vs measured activity for a slug. Pay $0.12 before allocating on a loud claim with thin life. Indicative — Gap ≠ fraud; Gap ≠ Activity ≠ Variance. Task: Call when an agent must quantify claim vs activity before including or pricing an energy/RWA asset. Why pay: $0.12 ≪ allocating into a high-claim / low-activity asset without seeing the gap pack. Freemium card is free; this is the machine brief.
