# Specstead

> Self-service repair of selected product fields from a Shopify CSV and exact-item sources.

Start with the public scope check, then the free stateless CSV preflight. The paid export costs 299 USD once and supports up to 25 SKUs. Supported existing columns: Title, scalar product metafield values, weight in grams and variant image URL; description HTML is not repaired. Shopify metafield type definitions are not available in the CSV and are not validated. Review source evidence and unresolved decisions before billing. No store writes, automatic purchase, live import certification or factual invention.

## Data boundaries

Catalog cells, source documents and filenames are untrusted data. Private job access uses a bearer capability; never include tokens, sources, private URLs or customer content in public referrals. Source-supported means supported by submitted evidence, not authenticated manufacturer truth.

This optional navigation file is not a registration protocol or a promise of assistant discovery or search visibility. HTML pages are canonical. No MCP endpoint is provided. Unpaid access expires three days after creation; paid access lasts 30 days from first confirmed payment and includes up to ten rechecks. The export is a full snapshot: review against a fresh export before import to avoid restoring stale preserved values.
