Up to 100 recent entries per source are checked each cycle; some publisher feeds provide fewer. Announcement topics are assigned automatically from explicit headline terms, not confirmed event outcomes. Dates on record cards are publication dates, not event dates. Releases marked as drafts or prereleases are excluded. Regulatory results require a crypto-related headline. Coverage is selective and bounded, not a complete record of network changes.

Releases and publisher feeds are checked approximately every six hours and US regulatory documents every twelve hours. The worker processes up to four due sources every fifteen minutes, so a full queue can add around two hours. Limits or outages delay updates; the last successful records remain visible. Source removal cannot be inferred from absence in a recent sample. No CoinMarketCal records are used here.
