    "answer": "The four-digit calendar year in which the first NFL season played after the AFL-NFL merger took effect was contested, as a number: 1970.",
    "season": "A league year beginning with its regular season; for the merged NFL the 1970 regular season opened on September 17, 1970 (Rams at Cardinals) and ended with Super Bowl V on January 17, 1971. The season is named for the calendar year it started, so the first season played after the merger took effect is the 1970 season, not 1971.",
    "merger": "The AFL-NFL merger was announced June 8, 1966, but the leagues continued to play separate schedules and hold separate championship games (Super Bowl I-IV were AFL-vs-NFL title games, not intra-league playoffs). It took effect for the 1970 season, when the two leagues were consolidated into one 26-team NFL split into the AFC and NFC and played a single unified regular-season schedule and playoff format. The first season played under the merger is therefore 1970.",
    "source": "Wikipedia, \"1970 NFL season\": it was \"the 51st regular season of the National Football League\" and \"the first after the consummation of the AFL-NFL merger\". Cross-checked against Wikipedia, \"AFL-NFL merger\", which dates integration of operations and schedules to 1970 (announced 1966). Pro-football-reference.com returned HTTP 403 to the fetch, so the citation rests on the two Wikipedia articles actually read.",

  "notes": "Panel-evidence question: no chain computation is possible or needed, so the recipe is { kind: \"panel\", source } and the source field names the articles actually read. Fact established: the AFL-NFL merger was announced June 8, 1966, but the leagues played separate schedules through the 1969 season; integration took effect for the 1970 season, which the 1970 NFL season article calls \"the first after the consummation of the AFL-NFL merger\" (26 teams, AFC/NFC, unified schedule, Super Bowl V on January 17, 1971). The first season played after the merger took effect is thus the 1970 season, so the four-digit calendar year requested is 1970. Read the two articles above and confirmed the window: block 26051516 was fetched from https://ethereum-rpc.publicnode.com and its hash equals the brief's toBlockHash exactly; fromBlock 26051219 and toBlock 26051516 are copied verbatim from .imd/reads/oracle.json. No value in this answer depends on chain state."
