Sources and methodology

What a source can establish

Valve documentation supports statements about its documented rules and products. It does not independently establish market share, typical player experiences, or commercial outcomes. Historical reporting is read in its own time; today’s documentation is not projected backward onto earlier rules.

Dates that mean something

Guide review dates record an editorial check. They are separate from announcement dates, effective dates, and historical events. A spelling fix does not justify presenting a page as a new development. Review dates describe source checks, not publication. Published revisions have separate dates; unpublished drafts have no publication date and are excluded from RSS and the sitemap. Local changes are labeled separately. Recurring monitoring has not been scheduled.

Corrections and uncertainty

When a claim cannot be supported, it is qualified or withheld. Substantive corrections should describe what changed and retain the original event date in the revision record. No monitored contact inbox is claimed for this edition.

Editorial attribution

Steam Updates Editorial Desk and Steam Updates Verification Desk are role-based aliases for AI-assisted content preparation and checks. They do not represent human reviewers, professional credentials, or legal approval. Verification covers specific sources and tests; it is not a blanket warranty.

Primary reading shelf

The source history has its own 64-entry bibliography, including contemporary reporting and public enforcement records.

Images and data

The device illustration and editorial diagrams were created for this site. They are conceptual drawings, not product photographs or hardware specification diagrams. We do not scrape SteamDB, collect game-library credentials, or reproduce a compatibility database.
