"description": "Prices one discount, free-shipping threshold or referral reward against contribution margin: cost per order, share of margin used, break-even lift, code leakage risks, and one recommended offer in two plain sentences. Use alone when you already have the offer, average order value and margin per product; otherwise run email-lifecycle."

offer-math
Reads: ../email-lifecycle/references/segments-cadence-offers.md (ladder and formula); AOV and margin per product or category from lifecycle/program.md (marketer-stated); the standing first-order offer from the shared Standing offer: fact (else the Brand record's business facts, read with file_read; never a search snippet); product records for price.
Does:
- Check the offer is allowed: the standing offer, or a step of a ladder the marketer approved. Welcome never deeper than the standing offer; first cart reminder never discounted; no discount to returning full-price buyers in cart flows; no code twice in 30 days. Anything else is a proposal, not a draft.
- Compute contribution per order, discount cost per order, share of contribution used, and the break-even lift, with the inputs shown. Free shipping: cost = average shipping cost × share of orders newly qualifying. Rewards (referral): cost per successful referral both sides vs contribution of the referred first order. Subscriptions and apps: use the subscription formula in the reference (store fee, months retained).
- Leakage: shared vs unique code (if the sign-up form shows a shared code, repeat that code and flag the leakage as a proposal naming the popup edit — never switch it silently), stacking, exclusions, expiry, which segments see it (are full-price buyers in them?).
- Recommend one — usually the cheapest offer that does the job, or a non-discount value (free shipping, gift with purchase, early access) — in two plain sentences.
- Unknown margin: show cost per order in money, say "margin unknown", and do not call it affordable.
Writes: an offer box placed next to the flow or send that uses it, and into the "awaiting your yes" list. The approved depth is saved in lifecycle/program.md; the approved depth stays in the program sheet (a standing offer the marketer states is written at SKILL step 9).
