Answer this question about chain 1 over blocks 26051648 to 26051946 (closing hash 0x7205ca49a730e2d01f5f3b18a1881ebe8ba071627e3d42361a0c392e32a03ceb), exactly as .imd/reads/oracle.json pins it: What air temperature, in whole degrees Celsius, did the last routine METAR for KJAN (Jackson-Medgar Wiley Evers International Airport, Jackson, Mississippi) issued at or before 17:00 UTC on 23 September 2026 (1:00 PM Eastern Daylight Time) report? Answer type: uint256. Evidence: panel. Definitions the requester fixed: - answer: the temperature in whole degrees Celsius as a non-negative whole number, taken from the temperature/dew-point group in the body of that METAR (for example 26 from "26/20"), not the tenths in the T-group remarks and not converted to Fahrenheit - subject: The weather observation at KJAN (Mississippi) on 23 September 2026. "The last routine METAR issued at or before 17:00 UTC" means the report of type METAR (not SPECI) whose observation time (the DDHHMMZ group) is the latest at or before 231700Z, typically about 1651Z-1656Z. The pinned chain and window of this request only timestamp it; the answer is a recorded weather observation, not a reading taken at the pinned block. - source: Answer from the archived METAR text itself, read from a public archive (aviationweather.gov data API, Iowa Environmental Mesonet ASOS archive, Ogimet, or NOAA/NWS observation history), quote the raw report in your notes, and name the source. - missing: If you cannot find that report, report that; do not estimate from a forecast, a nearby station, or an hourly summary. 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.

The answer is 29 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The last routine METAR for KJAN at or before 17:00 UTC on 23 September 2026 was observed at 16:54Z. I read it from the Iowa Environmental Mesonet ASOS archive (station JAN, report type 3, routine METAR only).

I used only that report and did not cross-check a second source. The recipe kind is "panel" with the IEM archive as its source. The first draft of the file was rejected because the `window` keys had to be in the order `oracle.json` gives them. I reordered them and the checker passed.

Checker passes. The last routine METAR for KJAN at/before 17:00Z on 2026-09-23 was `KJAN 231654Z ... 29/23 ...` (Iowa Environmental Mesonet ASOS archive), giving an air temperature of 29°C. Written to `artifacts/answer.json`.
The answer is 29 °C. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The report is the 1654Z observation, the last routine METAR at or before 1700Z. I read it from the Iowa Environmental Mesonet ASOS archive: `KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` The temperature group in the body is 29/23, so the answer is 29. The previous report (1554Z) read 27/23. The next one (1754Z) falls after the cutoff. I only checked this one source. The recipe is kind `panel` with that archive named as the source. The first check failed because `window` keys have to appear in the same order as in `oracle.json` (toBlock, fromBlock, toBlockHash). I reordered them.
Checker prints `ok`. Answer: 29°C, from KJAN 231654Z METAR (29/23) via IEM ASOS archive — the last routine METAR at or before 231700Z.
The answer is 29 °C, and `artifacts/answer.json` is written; the checker prints `ok`. The last routine METAR at or before 17:00 UTC was the 231654Z report. I read it from the Iowa Environmental Mesonet ASOS archive (station JAN). The raw report is: `KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` The temperature/dew-point group reads `29/23`, so the temperature is 29. The next report, at 231754Z, falls after the cutoff, so I did not use it. I only read the one archive, and I did not query aviationweather.gov as a second source. The recipe kind is `panel` with that archive named as the source. The checker's first run rejected the file because the `window` keys were in the wrong order. I reordered them to match `.imd/reads/oracle.json`, and the second run passed.
The KJAN air temperature is 29 °C, and `artifacts/answer.json` is written; the checker prints `ok`. The last routine METAR at or before 17:00 UTC was issued at 231654Z. The raw report, from the Iowa Environmental Mesonet ASOS archive (station JAN), reads: `KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` The temperature/dew-point group is 29/23, so the answer is 29. The file uses recipe kind `panel` with the IEM archive as its source. It copies the request id, chain and window from `.imd/reads/oracle.json`. I did not cross-check a second source; the aviationweather.gov query I tried returned an error.
I wrote `artifacts/answer.json` with an answer of 29 °C, and `check-answer.mjs` prints ok for it. The last routine METAR at or before 17:00 UTC is the 1654Z report from the Iowa Environmental Mesonet ASOS archive: `KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` The temperature/dew-point group is 29/23, so the temperature is 29. The first draft failed the checker because the window keys were in the wrong order. I reordered them to match `.imd/reads/oracle.json`.
The answer is 29 °C, and `artifacts/answer.json` is written; the checker prints `ok` for it. The last routine METAR for KJAN at or before 17:00 UTC on 23 September 2026 is the 1654Z report. I read it from the Iowa Environmental Mesonet ASOS archive: `KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` The temperature/dew-point group is 29/23, so the answer is 29. I checked the report type, so no SPECI report is involved. The recipe kind is `panel`, with the archive named as the source. I did not use a second source, since one archive was enough to state the fact.
The KJAN air temperature is 29 °C, and `artifacts/answer.json` is written; the checker printed `ok`. The last routine METAR at or before 17:00 UTC on 23 September 2026 was the 1654Z report. The source is the aviationweather.gov data API. The raw report reads: `METAR KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` The 29 comes from the 29/23 temperature/dew-point group in the body of the report. The recipe kind is `panel`, with that API query as the source. The checker first rejected the `window` object because its keys were in a different order than in `oracle.json`, so I reordered them to match.
The answer is 29 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints ok for it. The last routine METAR at or before 17:00 UTC is the 231654Z report. I read it from the Iowa Environmental Mesonet ASOS archive: `KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` The temperature group reads 29/23, so the temperature is 29. That report is type METAR, not SPECI. I took the figure from this one source only; I did not cross-check a second archive. The aviationweather.gov query I tried first returned "Invalid value for date", so I did not use it. The checker first rejected the file because the `window` keys were in the wrong order. I reordered them to match `oracle.json` and it passed.
The answer is 29 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The last routine METAR for KJAN at or before 17:00 UTC on 23 September 2026 is the 231654Z report. I read it from the aviationweather.gov data API: `METAR KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` The temperature/dew-point group is 29/23, so the temperature is 29. The next report, 231754Z, falls after 17:00 UTC. The file uses the `panel` recipe with the API URL as the source. It copies the request id, chain and window from `oracle.json`. The first check failed on key order in `window`, and I reordered it to match. I read only one source, not two.
The last routine METAR for KJAN at or before 17:00 UTC on 23 September 2026 reports 29 °C, and I wrote that to `artifacts/answer.json`. The checker prints `ok` for it. The raw report is `KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228`. The 29 comes from the 29/23 temperature/dew-point group. The source is the Iowa Environmental Mesonet ASOS archive, station JAN. Its METAR listing for 14:00–19:00 UTC showed 1654Z as the latest observation before 1700Z. I did not query a second archive. The recipe kind is `panel` with that source. The window and request id are copied from `.imd/reads/oracle.json`. The checker first rejected the file because it wants the window keys in the order `toBlock`, `fromBlock`, `toBlockHash`, so I reordered them.
The answer is 29 °C. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok` for it. The last routine METAR at or before 231700Z is the 231654Z report, which reads `29/23`. Raw text from the aviationweather.gov data API: `METAR KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` It is type METAR, not SPECI, and the report before it (231554Z) is earlier, so nothing later than 231654Z falls at or before 1700Z. I used one source only. The recipe is kind `panel`, and the notes quote the raw report and name the source. The checker first rejected the file because the `window` keys were in the wrong order. It has to be `toBlock`, `fromBlock`, `toBlockHash`. I reordered them and it passed.
The last routine METAR for KJAN at or before 17:00 UTC on 23 September 2026 reported 29 °C. I wrote `artifacts/answer.json` with that answer, and the checker prints `ok`. The report is the 1654Z observation: `METAR KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` I read it from two sources: the aviationweather.gov data API and the Iowa Environmental Mesonet ASOS archive. Both show the same report. The next routine report, 1754Z, is after the cutoff, so 1654Z is the latest one that counts. The first version failed the checker because the window keys were in the wrong order (`toBlock` must come before `fromBlock`). I reordered them to match `.imd/reads/oracle.json`. The recipe is kind `panel` with those two sources named.
The answer is 29 °C, and `artifacts/answer.json` passes `check-answer.mjs` (it prints `ok`). The last routine METAR at or before 17:00 UTC on 23 September 2026 is the 231654Z report. I read it from the Iowa Environmental Mesonet ASOS archive (station JAN, METAR report types only): `KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` The temperature/dew-point group is 29/23, so the temperature is 29. The next report, 231754Z, falls after 17:00 UTC. I used one source rather than two. The recipe is kind `panel`, naming the Mesonet archive as the source. The checker first rejected the answer because the `window` keys were in the wrong order. I reordered them to match `oracle.json` and it then passed.
**Answer: 29 °C.** I wrote it to `artifacts/answer.json`, and the checker prints `ok`. - **The report:** the last routine METAR at or before 17:00 UTC was the 16:54 UTC one: `METAR KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228`. The temperature/dew-point group is 29/23, so the answer is 29. - **Sources:** I read it from the aviationweather.gov data API, and the Iowa Environmental Mesonet ASOS archive has the same text. The recipe kind is `panel`, and it names both sources. - **Reports I left out:** the Iowa Environmental Mesonet archive also lists automated readings every five minutes, including one at 17:00 UTC showing 28/23. These are not routine METARs, so I ignored them, and the notes in the answer file say so. The first check failed only because the `window` fields were in a different order from `oracle.json`. I reordered them and the check passed.
The answer is 29 °C, and I wrote it to `artifacts/answer.json`; `check-answer.mjs` prints `ok` for the file. The last routine METAR for KJAN at or before 231700Z is the 231654Z report from the aviationweather.gov data API. Its raw text is: `METAR KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228`. The temperature/dew-point group reads 29/23. The recipe kind is `panel`, with the aviationweather.gov data API as its source. The request id, chain and window are copied from `.imd/reads/oracle.json`. I read only that one source and did not cross-check it against a second archive.
The answer is 29 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints ok for it. The last routine METAR at or before 1700Z on 23 September was the 231654Z report, read from the aviationweather.gov data API: `METAR KJAN 231654Z 35008KT 310V050 10SM CLR 29/23 A3012 RMK AO2 SLP195 T02890228` Its temperature/dew-point group is 29/23, so the temperature is 29. The next report, 231754Z, falls after 1700Z. I read only that one source rather than two. The first check failed because the `window` keys were in the wrong order. I reordered them to match `oracle.json` exactly. The recipe kind is `panel`, with the aviationweather.gov query as its source.
