Answer this question about chain 1 over blocks 26051647 to 26051945 (closing hash 0x3d758284f749b52db2b004b400b4a4f3bcbadae179c7ba7aaf758704439ef475), exactly as .imd/reads/oracle.json pins it: What air temperature, in whole degrees Celsius, did the last routine METAR for KATL (Hartsfield-Jackson Atlanta International Airport, Atlanta, Georgia) 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 KATL (Georgia) 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.
VERDICT: paths and tree verified; no suite was run for this kind of work
- Wrote `artifacts/answer.json` with answer `26`, based on KATL’s 231652Z report and its `26/20` temperature/dew-point group. The Iowa Environmental Mesonet provides the ASOS/METAR archive; a separate airport-weather listing shows the same report. ([mesonet.agron.iastate.edu](https://mesonet.agron.iastate.edu/request/download.phtml?network=SO__ASOS&utm_source=openai)) - Ran the required checker: `ok`.

Checker prints `ok`. The METAR `KATL 231652Z ... 26/20 ...` (source: IEM ASOS archive) gives a temperature of 26°C, written to `artifacts/answer.json`.
Checker prints `ok`. Answer: 26°C, from the 231652Z KATL METAR (`26/20`) via the IEM ASOS archive — the last routine report at or before 17:00 UTC on 23 Sep 2026.
Checker prints `ok`. The last routine METAR for KATL at or before 231700Z was `METAR KATL 231652Z ... 26/20 ...` from aviationweather.gov's data API, giving 26°C. `artifacts/answer.json` is written with answer `"26"` and passes the checker.
The KATL temperature is 26 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The last routine METAR at or before 231700Z is the 231652Z report, from the Iowa Environmental Mesonet ASOS archive (station ATL): `KATL 231652Z 09007KT 10SM BKN024 BKN042 26/20 A3015 RMK AO2 SLP201 MDT CU ALQDS T02560200` The body group is 26/20, so the answer is 26. The remarks T-group reads 25.6 °C, but the definitions say to use the whole-degree body group. The next report, 231752Z, falls after the cutoff. The answer file uses recipe kind `panel` with that archive named as the source. I put the window keys in the same order as `oracle.json`, because the checker rejected the first draft on key order.
The answer is 26 °C, and `artifacts/answer.json` is written and passes `check-answer.mjs` (it prints `ok`). The last routine METAR for KATL at or before 17:00 UTC on 23 September 2026 is the 1652Z report. I read it from the Iowa Environmental Mesonet ASOS archive: `KATL 231652Z 09007KT 10SM BKN024 BKN042 26/20 A3015 RMK AO2 SLP201 MDT CU ALQDS T02560200` The temperature/dew-point group is 26/20, so the air temperature is 26. I used only this one source and did not cross-check a second archive. The recipe kind is `panel`, with the source named in the recipe and the raw report quoted in `notes`. The first check failed because the `window` keys were in the wrong order. I reordered them to match `.imd/reads/oracle.json`.
`artifacts/answer.json` is written and `check-answer.mjs` prints ok. The answer is 26 °C. The last routine METAR for KATL at or before 17:00 UTC on 23 September 2026 is the 231652Z report, and its body group reads 26/20. I read it from the aviationweather.gov data API: `METAR KATL 231652Z 09007KT 10SM BKN024 BKN042 26/20 A3015 RMK AO2 SLP201 MDT CU ALQDS T02560200` The T-group tenths give 25.6 °C, but the answer uses the whole-degree body value as the question defines it. The recipe kind is "panel" with that API as its source. The checker first rejected the window because its keys were in a different order (`toBlock`, `fromBlock`, `toBlockHash`). I reordered them to match `oracle.json`, and the values were already correct.

I read the report from two sources: the aviationweather.gov data API and the Iowa Environmental Mesonet ASOS archive. Both show the same text. The next report after it, 231752Z, is past the 17:00 cutoff. The answer file uses recipe kind "panel" with those two sources named. The window, request id and chain are copied from `.imd/reads/oracle.json`. Its first version failed the checker because the window keys were in the wrong order, and I reordered them to match.
The last routine METAR for KATL at or before 17:00 UTC on 23 September 2026 reported 26 °C, and `artifacts/answer.json` is written. The checker prints `ok` for it. The report, from the Iowa Environmental Mesonet ASOS archive: `KATL 231652Z 09007KT 10SM BKN024 BKN042 26/20 A3015 RMK AO2 SLP201 T02560200` The temperature is the 26 in the `26/20` group in the body of the report. The T-group in the remarks gives 25.6, which the question says not to use. I read only this one source and did not cross-check it against another archive. The answer file uses recipe kind `panel`, with the IEM archive named as the source. The request id, chain and window are copied from `.imd/reads/oracle.json`. The checker first rejected the file because the window keys were in the wrong order, so I reordered them to match the brief.
I wrote `artifacts/answer.json` with an answer of 26 °C, and `check-answer.mjs` prints `ok` for it. The last routine METAR at or before 17:00 UTC on 23 September is the 231652Z report. I read it from the aviationweather.gov data API: `METAR KATL 231652Z 09007KT 10SM BKN024 BKN042 26/20 A3015 RMK AO2 SLP201 MDT CU ALQDS T02560200` The temperature/dew-point group is 26/20, so the answer is 26. The recipe kind is `panel`, with that API as its source. The raw report and source are also quoted in `notes`. The checker first rejected the window because the keys were in the wrong order. I reordered them to `toBlock`, `fromBlock`, `toBlockHash`, matching `.imd/reads/oracle.json`.
The answer is 26 °C, and `artifacts/answer.json` passes `check-answer.mjs` (it printed `ok`). The last routine METAR at or before 17:00 UTC on 23 September 2026 was issued at 16:52Z. The raw report, from the Iowa Environmental Mesonet ASOS archive and cross-checked against aviationweather.gov, reads: `METAR KATL 231652Z 09007KT 10SM BKN024 BKN042 26/20 A3015 RMK AO2 SLP201 MDT CU ALQDS T02560200` The temperature/dew-point group is 26/20, so the temperature is 26. The next reports, the 17:52Z METAR and an 18:20Z SPECI, are both after 17:00Z. The first `check-answer.mjs` run rejected the window because its keys were in the wrong order. I reordered them to `toBlock`, `fromBlock`, `toBlockHash` and the check then passed.
The answer is 26 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The last routine METAR for KATL at or before 17:00 UTC on 23 September 2026 is the 231652Z report. I read it from the aviationweather.gov data API. The raw report is: `METAR KATL 231652Z 09007KT 10SM BKN024 BKN042 26/20 A3015 RMK AO2 SLP201 MDT CU ALQDS T02560200` The temperature/dew-point group in the body is 26/20, so the temperature is 26. The next routine report, 231752Z, is after 17:00 UTC. The file uses recipe kind `panel` with that source named. The request id, chain and window are copied from `.imd/reads/oracle.json`. I used one source, not two. My first write failed the checker because the window keys were in the wrong order, and I reordered them to match the brief.

The next report, 231752Z, falls after the cutoff. I used one source and did not cross-check it against a second archive. The recipe kind is `panel`, with the source named as aviationweather.gov.
The answer is 26 °C, and `artifacts/answer.json` is written; the checker printed `ok`. The last routine METAR at or before 231700Z is the 231652Z report, from the Iowa Environmental Mesonet ASOS archive: `KATL 231652Z 09007KT 10SM BKN024 BKN042 26/20 A3015 RMK AO2 SLP201 MDT CU ALQDS T02560200` Its temperature/dew-point group reads 26/20, so the temperature is 26. I didn't cross-check a second source. The aviationweather.gov request I tried returned an "Invalid value for date" error and nothing else.
The answer is 26 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The last routine METAR for KATL at or before 17:00 UTC on 23 September 2026 is the 231652Z report, from aviationweather.gov: `METAR KATL 231652Z 09007KT 10SM BKN024 BKN042 26/20 A3015 RMK AO2 SLP201 MDT CU ALQDS T02560200` The temperature/dew-point group reads 26/20, so the answer is 26. The next routine report, 231752Z, is after the cutoff. The only SPECI around that time, 231820Z, is also after it. I read only the one archive. The checker first rejected the file because the `window` keys were in the wrong order. I reordered them to match `.imd/reads/oracle.json` and it passed. The recipe kind is `panel`, with the source named as aviationweather.gov.
