Answer this question about chain 1 over blocks 26051649 to 26051947 (closing hash 0x779cb990e9009ba1a8a15dab55a041bae0bb21454f81029131c14574d918c1b7), exactly as .imd/reads/oracle.json pins it: What air temperature, in whole degrees Celsius, did the last routine METAR for KFSD (Sioux Falls Regional Airport, Sioux Falls, South Dakota) 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 KFSD (South Dakota) 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

Checker prints `ok`. Answer: 16°C, from METAR KFSD 231656Z 16/12, sourced via the IEM ASOS archive.
The answer is 16 °C, and `check-answer.mjs` printed `ok` for `artifacts/answer.json`. The source is the Iowa Environmental Mesonet ASOS archive. The last routine METAR at or before 17:00 UTC on 23 September 2026 was the 1656Z report: `KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` Its temperature/dew-point group is 16/12, so the temperature is 16. The report is a routine METAR, not a SPECI. The file uses the panel recipe with that source named. The window matches `.imd/reads/oracle.json`; the checker rejected my first version because the `window` keys were in a different order, and I fixed that.
The answer is 16 °C, and `artifacts/answer.json` is written; the checker prints `ok`. The last routine METAR at or before 17:00 UTC is the 231656Z report. I read it from the Iowa Environmental Mesonet ASOS archive (station FSD, report type 3): `KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The temperature/dew-point group is 16/12, so the temperature is 16. The report before it (231556Z) read 15/12, and the next one (231756Z) falls after 17:00 UTC. I did not cross-check against a second archive. The recipe is kind `panel`, with the IEM archive named as the source. The window is copied from `oracle.json` with its keys in the same order, because the checker rejected the first draft when the key order differed.
The answer is 16 °C, and `artifacts/answer.json` is written. `check-answer.mjs` prints `ok` for it. The last routine METAR at or before 231700Z is the 231656Z report, read from the aviationweather.gov data API: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The temperature/dew-point group is 16/12. The archive shows no SPECI between 1656Z and 1700Z. The recipe kind is `panel`, with that API URL as the source. The request id, chain and window match `.imd/reads/oracle.json`. The checker requires the window keys in the same order as that file, so I wrote them that way. I read only this one source. I did not cross-check against Iowa Environmental Mesonet or Ogimet.
The answer is 16 °C, and `artifacts/answer.json` is written; the checker prints ok for it. The last routine METAR for KFSD at or before 17:00 UTC was issued at 231656Z. The raw report is: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The temperature/dew-point group reads 16/12, so the temperature is 16. I read the report from both the Iowa Environmental Mesonet ASOS archive and the aviationweather.gov data API, and they gave the same text. The only report after it in the archive is the 231756Z one, which falls outside the cutoff. The recipe is kind `panel`, with those two archives named as the source. The checker first rejected the file because the `window` keys were in a different order from `.imd/reads/oracle.json`, so I reordered them to match.
The answer is 16 °C, and `artifacts/answer.json` is written; the checker prints `ok`. The last routine METAR for KFSD at or before 17:00 UTC was observed at 231656Z. I read it from the Iowa Environmental Mesonet ASOS archive (station FSD): `KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The temperature/dew-point group is 16/12, so the temperature is 16. The next report, 231756Z, is after 17:00, so it doesn't count. I only used that one source. The file uses recipe kind `panel`, and the window is copied exactly from `.imd/reads/oracle.json`. The checker first rejected the window because it wants the keys in the order `toBlock`, `fromBlock`, `toBlockHash`, so I reordered them.
The answer is 16 °C, and `artifacts/answer.json` is written; the checker prints `ok`. The last routine METAR at or before 17:00 UTC is the 231656Z report: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` Its temperature/dew-point group is 16/12. The 231756Z METAR is after 17:00 UTC, and the SPECI reports are not routine METARs. I read only one source, the aviationweather.gov data API, which is named in the recipe. The first checker run rejected the window because the keys were in the wrong order, and I reordered them.
I wrote `artifacts/answer.json` with an answer of 16, and `check-answer.mjs` prints `ok` for it. The last routine METAR for KFSD at or before 17:00 UTC on 23 September 2026 is the 231656Z report. I read it from the aviationweather.gov data API: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The temperature/dew-point group is 16/12, so the air temperature is 16 °C. The file uses the `panel` recipe with that API named as the source, and the chain, window and closing hash are copied from `.imd/reads/oracle.json`. The checker first rejected the file because the `window` keys must be in the order `toBlock`, `fromBlock`, `toBlockHash`. I reordered them and it then passed. I used one source, not two.
The last routine METAR for KFSD at or before 17:00 UTC on 23 September 2026 reported 16 °C. I wrote `artifacts/answer.json` with answer "16", and the checker prints ok. The source is the Iowa Environmental Mesonet ASOS archive. The raw report is: `KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The temperature/dew-point group in the body reads 16/12, so the answer is 16. The next report in the archive is 231756Z, which is after the 17:00 cutoff. The checker first rejected the file because the window keys were in a different order from `.imd/reads/oracle.json`. I reordered them to match and it then passed.
The answer is 16 °C, and `artifacts/answer.json` is written; the checker prints ok for it. The last routine METAR at or before 231700Z is the 1656Z report. I read it from the Iowa Environmental Mesonet ASOS archive (station FSD). The raw report is: `KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The temperature/dew-point group reads 16/12, so the temperature is 16. I used one source, not two, and did not cross-check it against aviationweather.gov or Ogimet. The recipe kind is `panel`, with the IEM archive as its source. The first draft failed the checker because the window keys were in the wrong order; I reordered them to match `oracle.json` exactly.

The recipe kind is `panel`, with that archive named as the source. The first checker run rejected the file because the `window` keys were in a different order from `oracle.json`. I reordered them and it passed.
I wrote `artifacts/answer.json` with the answer 16, and `check-answer.mjs` prints ok for it. The last routine METAR at or before 17:00 UTC on 23 September 2026 is the 231656Z report, which gives 16/12, so the air temperature is 16 °C. I read it from the aviationweather.gov data API. The raw report is: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The next METAR (231756Z) and the SPECI at 231810Z both fall after 17:00 UTC, so neither counts. The recipe kind is `panel`, with the aviationweather.gov query as its source. The first check failed because I listed the window keys in a different order than `oracle.json`. I reordered them to match and the check passed.
The last routine METAR for KFSD at or before 17:00 UTC on 23 September 2026 reported 16 °C. `artifacts/answer.json` is written and `check-answer.mjs` prints ok. The raw report is `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122`. It has observation time 1656Z, and the temperature/dew-point group in the body is 16/12. The next report, 231756Z, falls after the cutoff. I found no SPECI issued after 1656Z and before 17:00 that would change this. I read the report from two sources: the aviationweather.gov data API and the Iowa Environmental Mesonet ASOS archive. Both return the same text. The recipe kind is `panel`, with those two sources named. The first checker run rejected the file because the `window` keys were in a different order from `oracle.json`. I reordered them and it passed. The answer, figure and definitions are unchanged.
The KFSD temperature is 16 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The source is the Iowa Environmental Mesonet ASOS archive (station FSD). Its raw report for 231656Z reads: `KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The 231556Z report showed 15/12, and the next one, 231756Z, falls after the 17:00 cutoff. I did not cross-check against a second archive. The answer file is a `panel` recipe, with the request id, chain and block window copied from `oracle.json`. The checker first rejected the window because its keys were in a different order from `oracle.json`, and I reordered them.
The answer is 16 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints ok for it. The last routine METAR at or before 17:00 UTC on 23 September 2026 is the 231656Z report: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The temperature group in the body is 16/12, so the temperature is 16. I read the same report on the aviationweather.gov data API and in the Iowa Environmental Mesonet ASOS archive. The recipe kind is `panel`, with those two sources named. The checker first rejected the window because the keys must be in the order `toBlock`, `fromBlock`, `toBlockHash`. I reordered them and it passed.
The answer is 16, and `artifacts/answer.json` passes `check-answer.mjs` (it printed `ok`). The last routine METAR at or before 231700Z is the 231656Z report. I read it from the aviationweather.gov data API: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` Its temperature/dew-point group is 16/12, so the temperature is 16 °C. The next report, the 231756Z METAR, falls after 17:00 UTC, and the 231810Z report is a SPECI, so neither counts. The recipe kind is `panel`, with the aviationweather.gov URL as the source. The raw report and source name are quoted in `notes`. I did not cross-check a second archive.
The answer is 16 °C, and `artifacts/answer.json` now passes `check-answer.mjs` with `ok`. The last routine METAR at or before 1700Z was the 231656Z report. I read it from the aviationweather.gov data API: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` Its temperature/dew-point group is 16/12. The 231756Z METAR and the 231810Z SPECI came after that report or weren't routine, so I excluded them. I only checked that one source, since the task asked for one or two. The recipe is kind `panel` with that API URL as the source. The checker first rejected the file because the `window` keys were in the wrong order. I reordered them to match `oracle.json` exactly.
The answer is 16 °C. I wrote it to `artifacts/answer.json`, and `check-answer.mjs` prints ok. The last routine METAR for KFSD at or before 17:00 UTC on 23 September was the 231656Z report. I read it from the aviationweather.gov data API: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` Its temperature/dew-point group is 16/12, so the temperature is 16. The 231810Z report is a SPECI and falls after 17:00 UTC anyway. The recipe is kind `panel` with that source named, and the window is copied exactly from `oracle.json`. I didn't check a second source.
The answer is 16 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The last routine METAR at or before 231700Z is the 231656Z report from the aviationweather.gov data API: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The temperature group reads 16/12, so 16. The next routine report, at 231756Z, falls after the cutoff. The SPECI at 231810Z is also excluded. The file uses recipe kind `panel` with that source. The checker first rejected the window because its keys were in a different order than in `oracle.json`, so I reordered them to match.
The answer is 16 °C, and `artifacts/answer.json` is written; the checker prints `ok`. The last routine METAR for KFSD at or before 17:00 UTC on 23 September 2026 is the 231656Z report. I read it from the aviationweather.gov data API: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The temperature/dew-point group in the body is 16/12, so the temperature is 16. The nearest SPECI reports (231810Z and later) fall after the cutoff anyway, and the report before it (231556Z) is earlier. I used one source rather than two. The recipe kind is `panel`, and the window and request id are copied from `.imd/reads/oracle.json`. The checker first rejected the window because the key order differed from the brief. I reordered the keys to `toBlock`, `fromBlock`, `toBlockHash`, and it passed.
The answer is 16 °C, and `artifacts/answer.json` is written; the checker prints ok. The last routine METAR at or before 17:00 UTC on 23 September 2026 is the one observed at 231656Z. I read it from the aviationweather.gov data API: `METAR KFSD 231656Z 15013KT 10SM OVC012 16/12 A3032 RMK AO2 SLP269 T01560122` The temperature/dew-point group is 16/12, so the temperature is 16. The 231810Z report is a SPECI and was skipped. I used a single source. The recipe kind is "panel", with the source named in the recipe and the raw report quoted in the notes. The first version failed the checker because the `window` keys were in a different order from `oracle.json`. I reordered them, and the block numbers and hash are unchanged.
