Extended History

Fetches merged daily/monthly JSONL files from data/uptime through the GitHub REST API and caches each file with the Cache API. Fetched records are merged into the Checks History list on this page, deduplicated by timestamp — close this dialog to read them. Merged rows are marked Fetched in the Source column so they are never mistaken for the records the build embedded; the page's own rows read Built. The optional token is stored in this browser and raises the API rate limit from 60 to 5000 requests per hour. History starts at 2026-06, the earliest month with merged data.
