Source hierarchy
- Official publisher announcements are the primary source for releases, rules and events.
- Marketplace observations describe active supply; they are not completed sales.
- Verified graded records require a completed-sale source and a matched card identity.
- Exchange rates are kept separate from the original source currency.
Original stories versus the Official Wire
The hourly monitor may archive source-linked updates in the Official Wire. Every source record remains noindex,follow: it exists for attribution and discovery, not as a substitute for the publisher's article.
Only a substantive News Desk article can enter the editorial index. It receives its own headline, lead, reporting structure, key facts, context, byline and permanent URL, while citing the official announcement prominently.
Publication gates
- An allowlisted official English-language primary source and a preserved source snapshot.
- A structured record of the names, dates, products, rules or event details used in the story.
- Original, substantive copy with multiple sections and reader context—not a rewritten headline or copied announcement.
- Visible authorship, publication and modification dates, primary-source citation and correction path.
Authorship, AI assistance and review
News Desk articles may be prepared with AI assistance from the cited source and a checked fact record. The article page carries that disclosure; AI assistance does not remove the source, substance or originality requirements.
When an article has not been independently reviewed by a named human editor, the page says so. The TCGMarketWatch News Desk is an organizational byline, not a claim of individual human authorship.
Corrections
Material factual or contextual changes update the editorial modified date without altering the archived primary-source record. Readers can report errors through the public corrections and contact pages.
