Answer this question about chain 1 over blocks 26038573 to 26038573, exactly as .imd/reads/oracle.json pins it: According to the US Naval Observatory's 2026 seasons table in UTC, did the September equinox occur during 22 September 2026 UTC? Write only artifacts/answer.json: the typed answer (bool) and the recipe that reproduces it.
VERDICT: paths and tree verified; no suite was run for this kind of work
Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: `false`** - The USNO seasons API (`tz=0`, `dst=false`) lists the September 2026 equinox as day 23, 00:05 — i.e. `2026-09-23T00:05:00Z`. - The pinned interval is `[2026-09-22T00:00:00Z, 2026-09-23T00:00:00Z)`, so the equinox falls five minutes past the exclusive end boundary → `false` per the false_rule. - Recipe is `{ "kind": "panel", "source": "https://aa.usno.navy.mil/api/seasons?year=2026&tz=0&dst=false" }`, which satisfies the `https://aa.usno.navy.mil/` source guard. - The block window (26038573) was copied exactly from the brief as the request anchor; per `chain_window_role`, chain time does not determine this fact.

Created [artifacts/answer.json](artifacts/answer.json) with answer `false`. Validation passed: `check-answer.mjs` printed `ok`.
Check passes. The USNO 2026 seasons table gives the September equinox as 2026-09-23T00:05 UTC, which falls outside the pinned window (22 Sept 2026 UTC), so `answer.json` records `false`.
check-answer.mjs prints `ok`. Answer written: the USNO 2026 seasons table gives the September equinox at 2026-09-23T00:05:00Z, outside the 22 September UTC window, so `answer: false`.
check-answer.mjs prints `ok`. `artifacts/answer.json` is written with answer `false` — the USNO 2026 seasons table gives the September equinox at 2026-09-23T00:05 UTC, which falls outside the 22 September UTC window.
