Feed-to-PDP parity playbook

Choose this playbook when the contradiction crosses team or system boundaries.

Owners

• Catalog: confirms the approved product and variant values.
• Storefront: checks visible content and structured data.
• Feed: checks transforms, localization, and export timing.
• Channel: checks diagnostics and reprocessing.

Steps

1. Pick a small set of affected products and variants.
2. Fix the comparison time, market, and currency.
3. Put every relevant field from every source in one table.
4. Trace each mismatch to its source or transform.
5. Correct the authoritative value or the transform that changed it.
6. Regenerate dependent feeds and markup.
7. Check the storefront and the channel independently.

Done when

• Identifiers, price, availability, title, and images agree for the same variant and market.
• Each transformed field has a named owner.
• The channel has processed the corrected export.
• A test or monitor now covers the failure that was missed.
