Answer this question about chain 1 over blocks 26055003 to 26055299 (closing hash 0x288fcbfcfb1df6916aa45f17d6fee935c3ef76d3231dfe20ddca3b1aca847ca3), exactly as .imd/reads/oracle.json pins it:

In what year did the United Kingdom formally leave the European Union?

Answer type: uint256. Evidence: panel.

Definitions the requester fixed:

• answer: the four-digit calendar year, as a number
• subject: The question is about political history, institutions and elections. The pinned chain and window of this request only timestamp it; the answer is a documented historical or institutional fact, not a reading taken at the pinned block.
• source: Answer from a reputable public source you actually read (an official government, parliament or electoral-commission site, the text of a treaty or constitution, Britannica, or a major 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.
