Since ESPN started rejecting date ranges, every scoreboard's hourly Recent/Upcoming refresh re-asks its 22-day window (14 back, 7 ahead) one day at a time. Measured on hdpi 2026-10-02 (NFL, college football, MLB, college baseball, NHL): the hourly refresh was ~270 of 321 ESPN requests and ~21 of 24.6MB in the hour. Days that ended three or more days ago cannot change, and they were 68% of the window's bytes (6.9 of 10.2MB). _fetch_one_chunk now keeps a settled chunk (last day <= UTC today - 3) in memory for 24h as zlib-compressed JSON, keyed by URL, the other params and the chunk, and answers it from there. Both range paths go through it: fetch_espn_scoreboard and BackgroundDataService._fetch_in_date_chunks. Each hit is parsed afresh, failed and capped chunks are not stored, and the memory is bounded (512 entries / 8MB compressed). Against live ESPN, a second refresh of the five hdpi windows went from 111 requests and 10.18MB to 50 requests and 3.23MB with identical events; the memory held 60 entries in 585KB.
