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 KDTW (Detroit Metropolitan Wayne County Airport, Detroit, Michigan) 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 KDTW (Michigan) 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 answer is **18°C**, from the 16:53Z METAR’s `18/11` temperature/dew-point group. I cross-checked the report in the [Aviation Weather Center archive](https://aviationweather.gov/api/data/metar?ids=KDTW&format=raw&date=2026-09-23T17%3A00%3A00Z&hours=1) and the [Iowa Environmental Mesonet archive](https://mesonet.agron.iastate.edu/cgi-bin/request/asos.py?station=DTW&data=metar&year1=2026&month1=9&day1=23&hour1=16&year2=2026&month2=9&day2=23&hour2=17&tz=Etc%2FUTC&format=comma&latlon=no&elev=no&missing=M&trace=T&direct=yes&report_type=1).

Checker passes. The last routine METAR at/before 17:00Z on 23 Sept 2026 for KDTW was 231653Z ("18/11"), giving a temperature answer of 18°C, sourced from the IEM ASOS archive; `artifacts/answer.json` is written and validated.
Checker prints `ok`. The last routine METAR for KDTW at/before 231700Z is `231653Z ... 18/11`, so the answer is 18°C, sourced from the IEM ASOS archive. `artifacts/answer.json` is written and validated.
The last routine METAR for KDTW at or before 17:00 UTC on 23 September 2026 reported 18 °C. I wrote 18 to `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. - **Report:** `METAR KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106`. The temperature group is 18/11. - **Source:** the aviationweather.gov data API (`https://aviationweather.gov/api/data/metar?ids=KDTW&format=raw&hours=72`). I read only this one source. - **Cutoff:** the next METAR is 231753Z, which falls after 17:00Z, so 231653Z is the last one that counts. - **Recipe:** kind `panel`, with that source named. The checker rejected the window block until its keys were in the order `toBlock`, `fromBlock`, `toBlockHash`, as in `oracle.json`. I fixed that.
The last routine METAR for KDTW 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 aviationweather.gov data API. The raw report is: `METAR KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` The next report is 231753Z, which is after 17:00Z, so 231653Z is the last one. The 18 comes from the "18/11" group in the body, not the T-group tenths. I read only that one source, and the recipe is kind `panel` naming it. The checker first failed because `window` had its keys in a different order from `oracle.json`. I reordered them to match, and it then passed.
KDTW's last routine METAR at or before 17:00 UTC on 23 September 2026 reported 18 °C, and `artifacts/answer.json` is written. `check-answer.mjs` prints `ok` for it. The report is the 1653Z observation. I read it from the aviationweather.gov data API (`https://aviationweather.gov/api/data/metar?ids=KDTW`). That is the only source I checked. Raw report: `METAR KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` The temperature/dew-point group reads 18/11, so the answer is 18. The next earlier routine report (231553Z) and later one (231753Z) are both outside the "latest at or before 231700Z" rule, so 231653Z is the right one. The file uses recipe kind `panel` with that source, and the window is copied from `oracle.json` with the checker's key order (`toBlock`, `fromBlock`, `toBlockHash`).
KDTW reported 18 °C, and I wrote that to `artifacts/answer.json`. The checker 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 DTW, routine reports only): `KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` The next routine report is 231753Z, which is after the cutoff. I used one source only; the aviationweather.gov query I tried returned an invalid-date error. The answer is `"18"` as a uint256 string, with recipe kind `panel` naming the IEM archive as the source.
The answer is 18 °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 is the 231653Z report. I read it from the aviationweather.gov data API: `METAR KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` Its temperature/dew-point group is 18/11, so the temperature is 18. The recipe kind is `panel` with that API URL as the source. I read only that one source, not a second archive. The checker rejected the first draft because the `window` keys were in a different order than in `oracle.json`. I reordered them to match and it then passed.
The answer is 18 °C, and `artifacts/answer.json` passes the checker (it prints `ok`). The last routine METAR at or before 17:00 UTC is the 1653Z report from the Iowa Environmental Mesonet ASOS archive (station DTW): `KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` The temperature/dew-point group reads 18/11. I did not check the aviationweather.gov API, which rejected my date parameter. The panel recipe names the IEM archive as its source, and the raw report is quoted in `notes`.
I wrote `artifacts/answer.json` with the answer 18 °C, and `check-answer.mjs` prints ok for it. The source is the aviationweather.gov data API. The last routine METAR at or before 231700Z is the 231653Z report: `METAR KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` The temperature group in the body reads 18/11, so the temperature is 18 °C. This is a panel answer, so the recipe kind is `panel` and I ran no chain scan. The checker first rejected the file because the `window` keys were in a different order from `oracle.json`. I reordered them and it passed. I did not look for a second source.
I wrote `artifacts/answer.json` with the answer 18, and `check-answer.mjs` prints ok for it. The last routine METAR at or before 17:00 UTC is the 231653Z report, read from the Iowa Environmental Mesonet ASOS archive (station DTW): `KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` Its temperature/dew-point group reads 18/11, so the air temperature is 18 °C. The recipe is kind "panel" with the Iowa Environmental Mesonet as the source. I checked only that one archive. The checker first rejected the file because the `window` keys were in a different order than in `oracle.json`. I reordered them to match, and it then passed.
The answer is 18 °C, and `artifacts/answer.json` passes `check-answer.mjs` (it printed `ok`). The last routine METAR for KDTW at or before 17:00 UTC on 23 September 2026 was issued at 1653Z. I read it from the aviationweather.gov data API: `METAR KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` The temperature/dew-point group is 18/11, so the temperature is 18. The next report, at 1753Z, is after the cutoff and was not used. The answer file uses recipe kind `panel`, with the request id, chain and window copied from `oracle.json`. It quotes the raw report in its notes. I did not run `scan.mjs`, since a panel question has no scan.
`artifacts/answer.json` is written with an answer of 18, and `check-answer.mjs` prints ok. The last routine METAR for KDTW at or before 17:00 UTC on 23 September 2026 is the 231653Z report. I read it from the aviationweather.gov data API: `METAR KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` Its temperature/dew-point group is 18/11, so the temperature is 18 °C. The next report, 231753Z, is after the cutoff, and no SPECI fell between the two. The recipe kind is "panel", with that API URL as the source. The first version failed the checker because the window's block fields were out of order and the last character of the block hash was missing. I corrected both.
The answer is 18 °C. `artifacts/answer.json` is written and the checker prints `ok`. The last routine METAR at or before 17:00 UTC was the 1653Z report. I read it from the Iowa Environmental Mesonet ASOS archive: `KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` The temperature/dew-point group reads 18/11. I did not cross-check against a second archive: the aviationweather.gov request I tried returned an invalid-date error, so the Mesonet archive is the only source. The recipe is `panel` with that source.
The answer is 18 °C, and `check-answer.mjs` prints ok for `artifacts/answer.json`. The last routine METAR at or before 17:00 UTC on 23 September 2026 is the 1653Z report.

I used only that one source, and the recipe kind is `panel`. The window in the file is copied from `.imd/reads/oracle.json`. The checker first rejected it because my keys were in a different order, and I fixed that.
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.

The next report, 231753Z, is after the cutoff. I used one source only, not a second archive. The recipe is kind `panel` with that source named. The checker first rejected the file because the `window` keys were in the wrong order; I reordered them to match `oracle.json` and it then 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 was the 1653Z report. Its temperature/dew-point group reads 18/11.

The request id, chain and window are copied from `oracle.json`. The checker rejected the window at first because the keys were in the wrong order, and I fixed the order.
The answer is 18 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints `ok` for it. The last routine METAR for KDTW at or before 231700Z is the 231653Z report. I read it from the aviationweather.gov data API: `METAR KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` The temperature/dew-point group is 18/11. The next report, 231753Z, falls after the cutoff. I used one source rather than two. The recipe kind is `panel`, with the aviationweather.gov API as its source. The request id, chain and window are copied from `oracle.json`. The checker first rejected the window because its keys were in a different order (`toBlock` before `fromBlock`). I reordered them and it passed.
The answer is 18 °C, and `check-answer.mjs` prints `ok` for `artifacts/answer.json`. The last routine METAR for KDTW at or before 17:00 UTC on 23 September 2026 was issued at 1653Z.

That agrees with the 17.8 °C in the T-group remark, which I did not use for the answer. The recipe kind is `panel`, with the aviationweather.gov query URL as its source. The request id, chain and window are copied from `.imd/reads/oracle.json`. The checker only accepts the window keys in the order `toBlock`, `fromBlock`, `toBlockHash`, so the file uses that order.

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. It comes from the Iowa Environmental Mesonet ASOS archive, and the same report appears in the aviationweather.gov data API: `METAR KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` The temperature/dew-point group is 18/11, so the answer is 18. The next report, 231753Z, is after the cutoff. The recipe is kind `panel` with those two sources named. The window is copied exactly from `oracle.json`. The checker first rejected the file because the window keys were in a different order than the pinned brief; I reordered them.
The answer is 18 °C, and `artifacts/answer.json` is written with recipe kind `panel`. The checker prints `ok`. The last routine METAR at or before 17:00 UTC on 23 September 2026 is the 231653Z report, from the aviationweather.gov data API: `METAR KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106` The 18 comes from the `18/11` group in the body of the report. The T-group in the remarks says 17.8, but the definitions call for the body group. No SPECI appeared between 231653Z and 1700Z; the next report in the listing is the 231753Z METAR. I only used that one source. The `window` keys had to be in the same order as in `oracle.json` for the checker to pass, and I fixed that.
