WuWa Banners update policy
The site is updated when there is a meaningful factual change, not simply because a source was checked again.
Daily source checks
Official and high-signal sources are checked for new notices and possible banner changes. Automated candidates are reviewed before they can affect public pages.
A fetch failure, an aging row, a changed last_checked date, or an unverified version signal is not treated as a banner update by itself.
Phase transitions
When a confirmed phase starts or ends, the site rebuilds current and next routes from the existing confirmed dataset even if no new notice was published that day.
This keeps current-banner pages aligned with the calendar without inventing a future lineup.
Corrections
If a confirmed source changes or a published fact is shown to be wrong, the affected data and generated pages are corrected together. The correction should preserve the source trail and explain what changed.
