Answer this question about chain 1 over blocks 26051219 to 26051516 (closing hash 0x5125eb3143546ed938bea346d6de20fea1f1b25ba53e72259c76656f43a39e6d), exactly as .imd/reads/oracle.json pins it: How many yards apart are the two goal lines on an American football field? Answer type: uint256. Evidence: panel. Definitions the requester fixed: - answer: the number, as a whole number - subject: The question is about the history, records and rules of American football and association football (soccer). The pinned chain and window of this request only timestamp it; the answer is a documented sports fact, not a reading taken at the pinned block. - source: Answer from a reputable public source you actually read (the league's or governing body's official site such as NFL.com, Pro Football Reference, FIFA, UEFA or the Premier League, Britannica, or a major sports news archive) and name it. - missing: If you cannot establish the fact from a source, report that; do not guess. Three steps: (1) read one or two sources that state the fact and note which; (2) write artifacts/answer.json with recipe kind "panel" and the source; (3) run node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs and fix what it prints. Nothing else needs reading first: the brief above is in .imd/reads/oracle.json, and .imd/reads/skills/oracle-assess/REFERENCE.md lists the recipe's fields if the checker asks for one.
VERDICT: paths and tree verified; no suite was run for this kind of work

The two goal lines on an American football field are 100 yards apart. `artifacts/answer.json` is written with that answer, and the checker prints `ok`. The only source I could actually read was Wikipedia's "American football field" article. It says the 100 yards between the goal lines is the "field of play" in the NFL rulebook. The NFL Operations page returned 404 and Britannica returned 403, so I couldn't cite either. That leaves a single secondary source, not one of the primary sites the brief names. The answer is `"100"` as a `uint256`, with a `panel` recipe pointing at the Wikipedia URL. The window and request id are copied from `oracle.json`. My first write had the window keys in a different order from the brief, and the checker rejected it until I matched the brief's order.
**Answer: 100 yards.** The [NFL Play Football glossary](https://playfootball.nfl.com/tackle/youth-and-high-school-tackle-football-glossary/) states that the playing field is 100 yards long.

The required checker returned `ok`.
I wrote `artifacts/answer.json` with the answer 100: the two goal lines are 100 yards apart. The checker prints `ok`. The source I read was the NFL Football Operations rulebook page (operations.nfl.com/the-rules/nfl-rulebook/). The fetch summarised it as 100 yards but added that the figure isn't spelled out word for word in the excerpt it saw. I noted that in `notes`. The figure also matches the standard field: 100 yards between goal lines plus two 10-yard end zones, 120 yards overall. That last part is from my own knowledge, not from the page. The recipe is kind `panel` with that source, and the request id, chain and window are copied from `.imd/reads/oracle.json`.
The two goal lines are 100 yards apart. `artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. - **Source read:** the Wikipedia article "American football field" (https://en.wikipedia.org/wiki/American_football_field). It says the 100 yards between the goal lines is the field of play, and the recipe cites that URL. - **Not confirmed:** I could not get a passage from NFL.com or Britannica, so I have only that one source. The note that this matches the NFL rulebook (100 yards plus two 10-yard end zones) comes from what I already knew, not from the rulebook page. - **Definition stated:** the answer excludes the two 10-yard end zones. - **Format:** the checker rejected the window until I put its keys in the order the brief uses (`toBlock`, `fromBlock`, `toBlockHash`). After that it passed. The block window is copied from the brief, but no chain data was used. This is a sports fact, not a reading at the pinned block.
