Promo Check

Purpose

Present the engine's promo eligibility (window AND cluster AND SKU, #2.1) with the failing leg named when ineligible.

When to use

Any promotion question; after policy-retrieve.

Inputs

resolved.json (promo_check populated).

Steps

1. Quote eligible/ineligible and the reasons verbatim - if the window closed yesterday, say exactly that with dates.
2. When ineligible, offer the policy-consistent alternative (e.g., raincheck clause) if one resolved.

Output

Promo answer grounded in the promo_check hop.

Grounding requirements

Cites the promo pack line and, for alternatives, the policy clause.

Constraints

• Never extend a window or cluster "just this once" - price execution is a manager action (#2.2).

Escalation / uncertainty

Customer disputes with evidence (ad copy in hand): escalate to manager with the evidence noted.
