Record whether the defect creates Block, Review, or no state change and show the affected intermediate value.

Repair the source or configuration, rerun the same cart, compare the observed checkout savings with the model, preserve both versions, and verify restoration.

Combination change monitor

Record which trigger expired the prior Ready or Review decision before editing evidence.

Discount restoration rehearsal

Restore the prior discount versions, mutual combination flags, protected cart fixture, checkout observation, seller policy, downstream campaign pointer, and monitoring state without activating anything.

The calculator cannot execute the restore or promotion; a named human retains activation and rollback authority.

Official rule boundary for promotion control log

Shopify documents product, order, and shipping discount classes; eligible combinations; product-first, order-second, shipping-last calculation order; one shipping discount code per order; a current maximum of 25 active automatic discounts and five product or order codes; channel, plan, checkout, and app considerations; best-combination selection; and checkout testing. Record acquisition dates because current behavior and eligibility can change.

This one-product, one-order, one-shipping model deliberately excludes Buy X get Y allocation, multiple same-line product discounts, multiple order-discount arithmetic, complex app functions, scripts, taxes, duties, refunds, gift cards, store credit, subscriptions, draft-order exceptions, and market-specific payment treatment unless a separate protected calculation reconciles them.

Privacy, release, and restoration for promotion control log

Use invented cart fixtures and aggregate evidence summaries only. Keep unpublished codes, customers, orders, addresses, payment details, staff identities, credentials, app settings, promotion calendars, cost records, private screenshots, and raw exports out of public content.

Before indexing, pass type, unit, integration, build, content, similarity, metadata, images, links, privacy, mobile, backup, deployment, and live checks. Search signals are later measurements; failed eligibility, checkout, or rollback evidence still stops release.
