Sources and editorial policy

Claim labels

Confirmed: Official or high-confidence public information.

Observed: Visible in public official material and still subject to change.

Reported: Reliable media report or rating-board listing, summarized in original wording.

Rumor: Community claim that is not officially confirmed.

Unknown: Common question without a reliable answer.

Editorial: Site analysis, policy, or cautious interpretation.

Source priority

Official pages and announcements come first, then official social channels or trailers, then reputable reporting. Community speculation is not treated as fact.

Claims this site will not publish yet

Release windows: Listed only when an official or reliable public source states them clearly; exact release dates stay unknown until stated directly.

Store expected dates: Store fields such as App Store expected dates are tracked as storefront metadata, not rewritten as precise publisher release-date announcements.

Rewards and codes: Official reward names may be summarized with caveats. Codes, quantities, odds, delivery rules, and access guarantees are not invented from screenshots, reposts, or community summaries.

Neighbor rosters: Not expanded into names, gifts, schedules, or tier-style advice until profile-level information is reliable.

Life-system values: No recipe values, farming timers, crafting costs, or progression numbers until they are visible in reliable public material.

Update and correction approach

When official information changes, this site should update the affected page, keep the wording cautious, and avoid silently turning an old unknown into a confirmed claim.

If a page needs a material change, the update should include a new checked date and keep the original source link reachable from the page or the sources list.
