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 KFAR (Hector International Airport, Fargo, North 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 KFAR (North 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
The last routine METAR before 17:00Z was observed at 1653Z and reported `18/11`, so the answer is **18°C**. The answer file passed the checker (`ok`). [artifacts/answer.json](/home/imd/.identitymd/work/d20fe46d-bc6a-414e-bdc8-c74383463f5a/365b9aaf-7ee1-4807-8778-9c0f9738031f/artifacts/answer.json)
The answer is 18 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The last routine METAR for KFAR at or before 17:00 UTC on 23 September 2026 is the 231653Z report. I read it from the aviationweather.gov data API: `METAR KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature group in the body is 18/11, so the temperature is 18. The SPECI at 231739Z and the METAR at 231753Z both fall after 17:00 UTC, so they don't count. The recipe kind is "panel" with the aviationweather.gov source. The request id, chain and window are copied from `.imd/reads/oracle.json`. I only read the one source, not two. The checker rejected the window on my first write because it wants the keys in the order `toBlock`, `fromBlock`, `toBlockHash`. I reordered them.

The last routine METAR at or before 17:00 UTC on 23 September 2026 is the 231653Z report: `METAR KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature/dew-point group reads 18/11, so the temperature is 18. The next report, a SPECI at 231739Z, is after 17:00 and a different report type, so it doesn't count. The Iowa Environmental Mesonet ASOS archive and the aviationweather.gov data API returned this same report. The recipe is `panel`, with those two as the named source. 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 18 °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 was the 231653Z report. The source is the aviationweather.gov data API. The raw report is: `METAR KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature/dew-point group in the body reads 18/11, so the air temperature is 18 °C. A later SPECI at 231739Z is not a routine report and falls after 17:00 UTC anyway. The recipe kind is `panel`, with the aviationweather.gov query as its source. The window and request id are copied from `.imd/reads/oracle.json`. My first write put the window keys in a different order and the checker rejected it, so I reordered them to match.
The answer is 18 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints ok for it. The last routine METAR at or before 17:00 UTC was issued at 231653Z: `KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature group in the body is 18/11, so the temperature is 18 °C. I read it from the Iowa Environmental Mesonet ASOS archive (station FAR). The recipe kind is "panel" and names that source. The first checker run failed because the `window` keys were in the wrong order (`toBlock` has to come before `fromBlock`). I reordered them and it passed.
The answer is **18 °C**. I wrote it to `artifacts/answer.json`, and the checker prints `ok`. - **Report used:** `KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106`. The temperature/dew-point group is 18/11, so the answer is 18. I did not use the 17.8 °C in the T-group remarks. - **Why this report:** it is the last one at or before 1700Z. The earlier 1617Z report was not the hourly routine report: it was off the hour and had no sea-level-pressure group. The 1653Z report has both. - **Source:** the Iowa Environmental Mesonet ASOS archive. The exact query URL is in the recipe, and the raw report is quoted in `notes`. I did not check it against a second archive. - **Fix needed:** the checker first rejected the file because the window's keys were in a different order from `oracle.json`. I reordered them to match exactly, and it then passed.
The answer is 18 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. My first version failed the checker because the `window` keys were in the wrong order. I reordered them to match `oracle.json`. The last routine METAR at or before 231700Z is the 231653Z report, from the aviationweather.gov data API: `METAR KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature group is 18/11, so the answer is 18. The SPECI at 231739Z and the METAR at 231753Z both fall after 1700Z, so I excluded them. The recipe is kind `panel` with that API as the source. The raw report is quoted in `notes`.
Checker prints `ok`. Answer: 18°C, from the KFAR 231653Z METAR (IEM ASOS archive), written to `artifacts/answer.json`.
The answer is 18 °C, and `artifacts/answer.json` is written; the checker prints `ok` for it. The last routine METAR at or before 17:00 UTC on 23 September 2026 is the 231653Z report. I read it from the aviationweather.gov data API: `METAR KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature group in the body is 18/11, so the air temperature is 18 °C. The later 231739Z report is a SPECI and was issued after 17:00 UTC, so it doesn't count. The recipe kind is `panel`, with that API URL as the source. The window is copied from `oracle.json`. The checker first rejected the file because the window keys were in the wrong order (`toBlock` must come before `fromBlock`), which I fixed.
Checker prints `ok`. The last routine METAR at/before 17:00 UTC on 23 Sep 2026 for KFAR was `KFAR 231653Z ... 18/11 ...` (IEM ASOS archive) — temperature **18°C**, written to `artifacts/answer.json`.
The answer is 18 °C, and `artifacts/answer.json` passes `check-answer.mjs` (it printed `ok`). The last routine METAR for KFAR at or before 17:00 UTC on 23 September 2026 was issued at 16:53Z: `KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` Its temperature/dew-point group is 18/11. I read it from the Iowa Environmental Mesonet ASOS archive for station FAR. The aviationweather.gov API rejected my date parameter, so I did not use it as a second source. The file uses the `panel` recipe with that source named, and the request id and window are copied from `oracle.json` by script.
The answer is 18 °C, and `artifacts/answer.json` is written; the checker prints `ok` for it. The last routine METAR at or before 17:00 UTC on 23 September 2026 was the 231653Z report. I read it from the aviationweather.gov data API. The raw report is: `METAR KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature/dew-point group is 18/11, so the answer is 18. I did not use the T-group tenths (17.8). The SPECI at 231739Z and the METAR at 231753Z are both after 17:00Z, so they don't count. The recipe is `panel` with the API URL as its source. The window is copied exactly from `.imd/reads/oracle.json`. The checker first rejected the file because it requires the `toBlock`, `fromBlock`, `toBlockHash` key order, so I reordered those keys.
The answer is 18 °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 231653Z report. I read it from the Iowa Environmental Mesonet ASOS archive (station FAR): `KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature/dew-point group is 18/11, so the temperature is 18. There was no SPECI between 1653Z and 1700Z in that archive listing. I only read the one source. The answer uses the panel recipe with that source named. The checker first rejected the window because the keys were in a different order from the brief. I reordered them to match, and the values were not changed.
The answer is 18 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The last routine METAR for KFAR at or before 17:00 UTC on 23 September 2026 is the 1653Z report, which I read from the aviationweather.gov data API: `METAR KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` Its temperature/dew-point group is 18/11. The 1739Z report for that day is a SPECI issued after 1700Z, so it doesn't count either way. The file uses the `panel` recipe with the API as its source. The request id and pinned window are copied from `oracle.json`. The checker first rejected the window because its keys were in the wrong order, and I reordered them to match.
The answer is 18 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The last routine METAR at or before 231700Z is the 231653Z report, from aviationweather.gov (raw METAR text for KFAR): `METAR KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature group is 18/11, so 18 °C. The only other report in that hour was a SPECI at 231617Z, which doesn't count as routine. I used a single source and did not cross-check it against a second archive. `artifacts/answer.json` uses the panel recipe with that source URL, and the window matches `.imd/reads/oracle.json`. The checker first rejected the file because the `window` keys were in a different order from the pinned brief, so I reordered them.
The answer is 18 °C, and `artifacts/answer.json` passes `check-answer.mjs` (it printed `ok`). The source is the Iowa Environmental Mesonet ASOS archive. The raw report is: `KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The 231617Z report is earlier but is a SPECI (no SLP group), so the 231653Z report is the last routine METAR at or before 17:00 UTC. Its temperature/dew-point group reads 18/11. The checker rejected the first draft because the `window` keys were in the wrong order (`toBlock`, `fromBlock`, `toBlockHash`). I reordered them and it now passes.
The last routine METAR for KFAR at or before 17:00 UTC on 23 September 2026 reported 18 °C. I wrote `artifacts/answer.json` with `"answer": "18"`, and `check-answer.mjs` prints ok. The source is the Iowa Environmental Mesonet ASOS archive (station FAR). The raw report is: `KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The next report, 231739Z, is after 17:00, so it doesn't count. I read only this one archive, not a second source. The recipe kind is `panel`, with that archive as the source. The checker first rejected the window because the keys weren't in the order it expects (`toBlock`, `fromBlock`, `toBlockHash`). I reordered them and it passed.
The answer is 18 °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 231653Z report, from the aviationweather.gov data API: `METAR KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature group reads 18/11, so 18. The 231753Z METAR is after 17:00 and the 231739Z SPECI is not a routine METAR, so both are excluded. I used the panel recipe with the aviationweather.gov query URL as its source, and quoted the raw report in `notes`. The first version of the file failed the checker because the `window` keys were in the wrong order, and I fixed that.
The last routine METAR for KFAR at or before 17:00 UTC on 23 September 2026 reported 18 °C, and I wrote that to `artifacts/answer.json`. The checker prints `ok` for it. The report comes from the Iowa Environmental Mesonet ASOS archive (station FAR, 23 September 2026 UTC). Its raw text is: `KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature/dew-point group is 18/11, so the answer is 18. This is a plain METAR, not a SPECI. The next one after it is 231753Z, which is past the cutoff. The first write failed the checker 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 archive named as the source. The request id, chain and window are copied from the brief.
The answer is 18 °C, and `artifacts/answer.json` is written. `check-answer.mjs` prints ok for it. The source is the aviationweather.gov data API.

Its temperature/dew-point group is 18/11. The later 231739Z report is a SPECI, so I excluded it. The recipe is `panel` with the API URL as its source. The window is copied exactly from `oracle.json`. The checker first rejected my window because the keys were in a different order, so I reordered them to match.
The answer is 18 °C, and `artifacts/answer.json` now passes the checker (it prints `ok`). The last routine METAR at or before 17:00 UTC was the 231653Z report: `METAR KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The next report, SPECI 231739Z, falls after 17:00 UTC and is a SPECI, so it doesn't count. I took the report text from the Iowa Environmental Mesonet ASOS archive and cross-checked it against the aviationweather.gov data API. The first version failed the checker because the window keys were in a different order from `oracle.json`. I reordered them to match.
The answer is 18 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The recipe kind is `panel`, with the Iowa Environmental Mesonet ASOS archive named as the source. My first draft failed the checker because the window keys were in the wrong order. I reordered them and it passed. The last routine METAR at or before 231700Z is the one observed at 231653Z. The raw report is: `KFAR 231653Z 15018G28KT 10SM BKN028 18/11 A3028 RMK AO2 PK WND 14028/1653 SLP256 T01780106` The temperature/dew-point group in the body reads 18/11, so the temperature is 18 °C. I read only the IEM archive, filtered to routine METARs. The request ID, chain and window match `.imd/reads/oracle.json`.
