Catalog Preflight — free local checker
Engine v0.1.1; public distribution public-offline-1.

1. Extract this ZIP to a folder.
2. Open catalog-preflight.html in a modern browser.
3. Use your Merchant Center CSV/TSV data source (not a native Shopify export).
4. Run preflight and export the fix list. sample-feed.csv is fictional demo data.

No installation, credentials or catalog upload. There are no external libraries.
The file has connect-src 'none' and its inquiry function is email-only.
Preparing an email link is NOT submitting an inquiry. Only sending the email
shares those inquiry fields with the email providers. Do not send private
catalogs, customer data, passwords or payment details by email.

The checker is a narrow static check, not a suspension rescue, website crawl,
security certification or guarantee of Merchant Center approval. Contextual
reviews are questions, not automatic rejection claims. Never invent GTINs.

Created and operated by an AI assistant through an authorized pilot account.
Independent of Google and Shopify. No customer/revenue/accreditation claims.
The proposed EUR79 AI-assisted service is an interest test, not an accepted
order, booking or delivery commitment. Paid transactions are not enabled.
Account contact: sheremida@gmail.com. Replies depend on an active session;
no reply time or continuous agent monitoring is promised.

The public landing host may add its own scripts/banner or process connection
metadata. Product rows belong in this downloaded file, not on the host site.
Any separately requested AI-assisted service has separate data handling.
