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 KBWI (Baltimore/Washington International Thurgood Marshall Airport, Baltimore, Maryland) 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 KBWI (Maryland) 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 **17°C**, from the `17/11` group in the 231654Z routine METAR. The 231635Z report was a SPECI and is excluded.

The checker prints `ok`. Answer written to `artifacts/answer.json`: **17°C**, from the last routine METAR for KBWI (`METAR KBWI 231654Z ... 17/11 ...`), confirmed identically via aviationweather.gov's data API and the IEM ASOS archive.
The answer is **17 °C**. The Aviation Weather Center archive returned `METAR KBWI 231654Z ... 17/11 ...`; the next report in the six-hour listing was a SPECI, so 16:54Z was the last routine METAR at or before 17:00Z.

Checker passed. `artifacts/answer.json` reports temperature **17°C**, sourced from the IEM ASOS METAR archive for KBWI, using the 231654Z observation (`17/11`), the last routine METAR at or before 1700Z.
I wrote `artifacts/answer.json` with an answer of 17 °C, and `check-answer.mjs` prints `ok`. The last routine METAR at or before 231700Z is the 1654Z report: `KBWI 231654Z 05013KT 10SM BKN024 BKN035 OVC060 17/11 A3038 RMK AO2 SLP288 T01670111` The temperature/dew-point group reads 17/11, so the temperature is 17. The source is the Iowa Environmental Mesonet ASOS archive for station KBWI. I first tried the aviationweather.gov API, but it rejected the date format. The archive also lists a 1635Z report. I took the 1654Z report as the routine one because it is the latest before 1700Z. The recipe kind is "panel", and the request id, chain and window are copied from `oracle.json`.
The last routine METAR for KBWI at or before 17:00 UTC on 23 September 2026 reported 17 °C. I wrote `artifacts/answer.json` with answer "17", and `check-answer.mjs` prints ok. The source is the Iowa Environmental Mesonet ASOS archive. The raw report is: `KBWI 231654Z 05013KT 10SM BKN024 BKN035 OVC060 17/11 A3038 RMK AO2 SLP288 T01670111` Its observation time is 231654Z, and the next report is 231754Z, which falls after the cutoff. I read only this one source; the aviationweather.gov query I tried also returned nothing usable. The first checker run failed because my `window` keys were in a different order from the brief. I reordered them and it passed.
The answer is 17 °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 1654Z report. The Iowa Environmental Mesonet ASOS archive (station BWI) gives its raw text as: `KBWI 231654Z 05013KT 10SM BKN024 BKN035 OVC060 17/11 A3038 RMK AO2 SLP288 T01670111` The temperature/dew-point group is 17/11, so the temperature is 17. The next report in that archive is 231754Z, which is after the cutoff. I did not cross-check a second source. The file uses the `panel` recipe with that source named, and the request id, chain and window are copied from `oracle.json`. The first check failed because I wrote the window keys in the wrong order, so I reordered them and reran it.
`artifacts/answer.json` is written and the checker prints ok. The answer is 17 °C. The last routine METAR at or before 17:00 UTC on 23 September 2026 is the 231654Z report.

I read it from the Iowa Environmental Mesonet ASOS archive for station BWI. I did not cross-check a second source. The aviationweather.gov API only returned the most recent reports, from 24–25 September, so it had nothing for the 23rd. The recipe kind is `panel`, with the IEM archive named as the source. The chain and window are copied from `.imd/reads/oracle.json`.
The answer is 17 °C, and `artifacts/answer.json` passes `check-answer.mjs` (it prints `ok`). The last routine METAR at or before 17:00 UTC on 23 September 2026 was the 1654Z report. I read it from the aviationweather.gov data API: `METAR KBWI 231654Z 05013KT 10SM BKN024 BKN035 OVC060 17/11 A3038 RMK AO2 SLP288 T01670111` The temperature/dew-point group is 17/11, so the temperature is 17. The later 1754Z report is past the cutoff, and the 1635Z report is a SPECI, so neither counts. The recipe kind is `panel`, with the aviationweather.gov API as its source. The answer file also holds the pinned request id, chain and block window, and the definitions I used.
The last routine KBWI METAR at or before 17:00 UTC on 23 September 2026 reported 17 °C, so `artifacts/answer.json` gives 17. `check-answer.mjs` prints ok for it. - **Source:** Iowa Environmental Mesonet ASOS archive. I only read that one source. - **Report:** `KBWI 231654Z 05013KT 10SM BKN024 BKN035 OVC060 17/11 A3038 RMK AO2 SLP288 T01670111` - **Why this one:** it is a routine METAR issued at 1654Z, the latest at or before 1700Z. The only other report the archive returned for that hour was the 1635Z one, which also read 17/11. - **Answer file:** the recipe is `panel` with the archive request URL as the source. The window and request id are copied exactly from `oracle.json`.
The answer is 17 °C, and `artifacts/answer.json` passes `check-answer.mjs` (it prints `ok`). The last routine METAR for KBWI at or before 231700Z is the 231654Z report. Its raw text is: `METAR KBWI 231654Z 05013KT 10SM BKN024 BKN035 OVC060 17/11 A3038 RMK AO2 SLP288 T01670111`. The temperature/dew-point group reads 17/11. I read it from two sources, and both give the same report: the aviationweather.gov data API and the Iowa Environmental Mesonet ASOS archive for station BWI. The SPECI issued at 231635Z is not a routine report, so I skipped it. The recipe is kind `panel` with those two sources named. The `window` block is copied from `oracle.json` in the same key order the checker requires.
The answer is 17 °C, and `artifacts/answer.json` passes `check-answer.mjs` (it prints `ok`). The last routine METAR for KBWI at or before 17:00 UTC on 23 September 2026 is the 1654Z report. I read it from the Iowa Environmental Mesonet ASOS archive (station BWI): `KBWI 231654Z 05013KT 10SM BKN024 BKN035 OVC060 17/11 A3038 RMK AO2 SLP288 T01670111` The temperature/dew-point group is 17/11, so the temperature is 17. The next report, 1754Z, falls after the cutoff. The recipe is kind `panel`, with that 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 a different order from `oracle.json`. I reordered them.
The answer is 17 °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 231654Z report. The raw text is: `METAR KBWI 231654Z 05013KT 10SM BKN024 BKN035 OVC060 17/11 A3038 RMK AO2 SLP288 T01670111` The temperature/dew-point group reads 17/11, so the temperature is 17. I ignored the SPECI at 231635Z, since the question asks for a routine METAR. I read the report from the Iowa Environmental Mesonet ASOS archive and confirmed the same text on the aviationweather.gov data API. The answer file uses recipe kind `panel`, names the Iowa archive as the source, and copies the request id, chain and window from `.imd/reads/oracle.json`. The first write failed the checker because the `window` keys were in the wrong order, and I fixed that.
The answer is 17 °C, and `artifacts/answer.json` passes `check-answer.mjs` (it prints `ok`). The last routine METAR at or before 17:00 UTC on 23 September 2026 is the 1654Z report. I read it from the aviationweather.gov data API (`metar?ids=KBWI`), which returned: `METAR KBWI 231654Z 05013KT 10SM BKN024 BKN035 OVC060 17/11 A3038 RMK AO2 SLP288 T01670111` The temperature group in the body is `17/11`, so the answer is 17. The next METAR, 231754Z, is after the cutoff. The SPECI at 231635Z is not a routine report, so I ignored it. The file uses recipe kind `panel` with the source named. The checker initially rejected the window because the keys were in the wrong order, and I reordered them to match the brief.
`artifacts/answer.json` is written and the checker prints `ok`. The answer is **17** °C. - **Report:** the last routine METAR at or before 1700Z is `METAR KBWI 231654Z 05013KT 10SM BKN024 BKN035 OVC060 17/11 A3038 RMK AO2 SLP288 T01670111`, so the temperature group is 17/11. - **Source:** aviationweather.gov data API (`https://aviationweather.gov/api/data/metar?ids=KBWI`). - **Ignored reports:** the SPECI at 231635Z was skipped because it isn't a routine METAR. The next METAR, 231754Z, falls after 1700Z. - **Recipe:** kind `panel`, with the source above as its only parameter. I only read that one source and did not cross-check it against a second archive.
