Capture dates because settings and eligibility can change.

Use invented cart fixtures and aggregate evidence summaries only. Keep customers, delivery addresses, order rows, payment data, negotiated carrier rates, labels, contracts, staff identities, credentials, unpublished promotions, app settings, cost ledgers, private screenshots, and raw exports out of public content.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 profile, market, checkout, ownership, or rollback evidence still stops release.
