Answer this question about chain 1 over blocks 26051650 to 26051948 (closing hash 0x9145f1a5ec87a1a12630d8315d4d42da51b5f490af9494fa9e70ff97f1d39e06), exactly as .imd/reads/oracle.json pins it: What air temperature, in whole degrees Celsius, did the last routine METAR for KCRW (Yeager Airport, Charleston, West Virginia) 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 KCRW (West Virginia) 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.

Done. `artifacts/answer.json` written with answer 22°C (from METAR KCRW 231654Z: `22/15`), checker prints `ok`, and git status is clean (file is untracked as required).
The answer is 22 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints ok for it. The report is the routine METAR observed at 231654Z, the latest one at or before 231700Z. I read it from the Iowa Environmental Mesonet ASOS archive (station CRW): `KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 ...

The recipe kind is "panel", with that archive named as the source. The checker rejected my first attempt because the `window` keys had to be in the order `oracle.json` gives them (`toBlock`, `fromBlock`, `toBlockHash`). I reordered them and it passed.
Checker prints "ok". No durable/applicable user-taught lesson here worth saving. Task complete: `artifacts/answer.json` reports temperature 22°C from the 231654Z KCRW METAR (22/15), sourced from the IEM ASOS archive.
The answer is 22 °C, and `artifacts/answer.json` is written; the checker prints `ok`. The last routine METAR for KCRW at or before 17:00 UTC on 23 September 2026 is the 1654Z report. I read it from the aviationweather.gov data API: `METAR KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` The temperature/dew-point group in the body reads 22/15, so the answer is 22. The next METAR was issued at 1754Z, after the cutoff, and no SPECI is used. I used one source rather than two. The recipe kind is `panel`, with the aviationweather.gov query as its source. The window is copied exactly from `oracle.json`.
Checker prints `ok`. The last routine METAR at/before 17:00 UTC on 2026-09-23 for KCRW was `231654Z ... 22/15 ...` (IEM ASOS archive), giving an answer of **22°C**. Written to `artifacts/answer.json`.
Check passes with `ok`. Answer: 22°C, from the KCRW 231654Z METAR (`22/15` temp/dewpoint group), sourced from the IEM ASOS archive — written to `artifacts/answer.json`.
The answer is 22 °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 231654Z report. I read it from the aviationweather.gov data API: `METAR KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` The temperature/dew-point group is 22/15, so the answer is 22. The next routine report, 231754Z, falls after the cutoff, so it doesn't count. The recipe is kind `panel` with that source named, and the raw report is quoted in `notes`. The checker first rejected the file because the `window` keys were in a different order from the one in `oracle.json`. I reordered them to match.
The answer is 22 °C, and `check-answer.mjs` prints `ok` for `artifacts/answer.json`. The last routine METAR at or before 17:00 UTC is the 1654Z report, read from the Iowa Environmental Mesonet ASOS archive (station CRW): `KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 ... T02170150` The temperature/dew-point group in the body reads 22/15, so the temperature is 22. The tenths in the T-group remarks (21.7) were not used. The 1554Z and 1754Z reports both read 21, but the 1754Z one is after 17:00 UTC and doesn't count. The recipe is kind `panel` with that source. The window is copied exactly from `.imd/reads/oracle.json`; the checker rejected my first version because the keys were in a different order, and I fixed that.
Checker passes. Answer: 22°C, from the KCRW 231654Z METAR (22/15) via the IEM ASOS archive, written to `artifacts/answer.json`.
The answer is 22 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The source is the aviationweather.gov data API. The last routine METAR at or before 231700Z is the 231654Z report: `METAR KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` The temperature/dew-point group reads 22/15, so the temperature is 22. The next METAR was 231754Z, after the cutoff, and there was no METAR or SPECI between 231654Z and 231700Z. The recipe kind is `panel`, and the window is copied exactly from `oracle.json`. The checker first rejected the file because my window keys were in the wrong order, and I fixed that. I read only the aviationweather.gov feed, not a second archive.
The answer is **22 °C**, and `artifacts/answer.json` passes the checker (it prints `ok`). I took it from the Iowa Environmental Mesonet ASOS archive. The last routine METAR for KCRW at or before 231700Z is: `KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 … T02170150` Its temperature/dew-point group is `22/15`, so the answer is 22. As the definitions require, I didn't use the 21.7 °C reading in the remarks at the end. The file uses the `panel` recipe, with the archive URL as its source and the raw report quoted in the notes. I read only this one archive and didn't check a second source against it.
The answer is 22 °C, and `artifacts/answer.json` is written; the checker prints `ok` for it. The last routine METAR at or before 17:00 UTC is the 231654Z report from the aviationweather.gov data API. The raw report reads: `METAR KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150`. Its temperature/dew-point group is 22/15. No SPECI issued between 1654Z and 1700Z appears in the API output. I used one source, the aviationweather.gov data API, rather than two. The recipe kind is `panel`, with that API URL as its source.
The answer is 22 °C. I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok`. The last routine METAR at or before 17:00 UTC is the 231654Z report, from the aviationweather.gov data API: `METAR KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` The temperature/dew-point group reads 22/15, so the temperature is 22. The next report, 231754Z, falls after 17:00 UTC, and no SPECI was involved. I read only that one source; the Iowa Environmental Mesonet request was rate-limited, so I have no second source. The recipe kind is `panel`, naming that API as the source, and the request id, chain and window are copied from `oracle.json`.
The answer is 22 °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 231654Z report. I read it from the Iowa Environmental Mesonet ASOS archive (station CRW). The raw report is: `KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` The temperature/dew-point group reads 22/15, so the temperature is 22. I did not cross-check a second source. The aviationweather.gov query rejected my date format and I did not retry it. The recipe is kind `panel`, with the IEM archive named as the source.
The answer is 22 °C, and `artifacts/answer.json` is written; the checker prints `ok` for it. The last routine METAR for KCRW at or before 17:00 UTC on 23 September 2026 is the 1654Z report. I read it from the Iowa Environmental Mesonet ASOS archive: `KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` The temperature/dew-point group reads 22/15, so the temperature is 22. The recipe is kind `panel` with that archive as the source. I did not cross-check a second source; the aviationweather.gov query I tried first returned "Invalid value for date". The checker first rejected the file because the `window` keys were in a different order from `oracle.json`. I reordered them to match.
The answer is 22 °C, and `check-answer.mjs` printed `ok` for `artifacts/answer.json`. I read the report from the aviationweather.gov data API. The last routine METAR at or before 17:00 UTC on 23 September 2026 is the 231654Z one: `METAR KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` The next report, 231754Z, is after the cutoff. The 22 comes from the `22/15` group in the body of the report. The file uses recipe kind `panel` with that API URL as the source. I only consulted that one source. I did not cross-check it against another archive. The checker first rejected the file because the `window` keys were in a different order from `oracle.json`. I reordered them and it passed.
The answer is 22 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints `ok` for it. The last routine METAR for KCRW at or before 17:00 UTC on 23 September 2026 was issued at 1654Z. I read it from the Iowa Environmental Mesonet ASOS archive: `KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` The temperature group in the body reads 22/15, so the temperature is 22. I checked only this one source; the next report in the archive is 1754Z, which is after the cutoff. The first check failed because the window keys were in the wrong order. I reordered them to match `oracle.json` and the check then passed. The recipe is kind `panel` with the IEM archive as its source.
The last routine METAR for KCRW at or before 17:00 UTC on 23 September 2026 reported 22 °C, and the checker prints `ok` for `artifacts/answer.json`. The report is the 1654Z observation from the Iowa Environmental Mesonet ASOS archive (station CRW): `KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` The 22 comes from the `22/15` group in the body, as the definition requires, not from the T-group tenths (21.7). I used only the IEM archive, not a second source. The answer file uses the "panel" recipe naming that source. The first checker run rejected it because the window keys were in a different order from `oracle.json`. I reordered them and it passed.
The answer is 22 °C, and `artifacts/answer.json` is written. `check-answer.mjs` prints ok. The last routine METAR at or before 17:00 UTC on 23 September 2026 was issued at 231654Z. I read it from the aviationweather.gov data API: `METAR KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` The temperature/dew-point group in the body reads 22/15, so the temperature is 22. The next routine METAR, 231754Z, falls after 17:00 UTC. The recipe kind is "panel" with the source named. The window is copied exactly as the brief pins it. The checker first rejected the answer because the window keys were in a different order from the brief, and I reordered them.
The answer is 22 °C, and `artifacts/answer.json` passes the checker (it printed `ok`). The last routine METAR for KCRW at or before 231700Z is the 231654Z report, from aviationweather.gov: `METAR KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` Its temperature/dew-point group is 22/15, so the temperature is 22. The recipe kind is `panel`, with the aviationweather.gov query as the source. The window is copied from `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 passed.
The answer is 22 °C, and the checker prints `ok` for `artifacts/answer.json`. That is the temperature in the last routine METAR for KCRW at or before 17:00 UTC on 23 September 2026. The source is the aviationweather.gov data API. Its raw report for that observation is: `METAR KCRW 231654Z 11007KT 10SM SCT025 BKN065 BKN100 22/15 A3023 RMK AO2 SLP229 OCNL LTGCG DSNT SW AND NW CB DSNT SW AND NW T02170150` The temperature/dew-point group is 22/15. The next routine METAR, at 231754Z, falls after the cutoff. I used only this one source, not a second archive. The answer file uses the `panel` recipe with that API URL as the source. The checker first rejected the file because the `window` keys were in a different order than in `oracle.json`. I reordered them and re-ran it.
