Item guids are hashes of the row contents, so they don't change when new rows are added. Responses carry an `ETag` (hash of the history) and answer `If-None-Match` with a 304 when nothing changed.\n\n## Implementation\n\nThe parser (`commitfest.ts`) uses cheerio to locate the table following the `	History
