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 KBIL (Billings Logan International Airport, Billings, Montana) 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 KBIL (Montana) 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
Recorded **17°C** from the archived report `METAR KBIL 231653Z ... 17/12 ...`.

Validation passed: `ok`.
artifacts/answer.json is written (untracked, as required) and check-answer.mjs prints "ok". Found the report via IEM ASOS archive: `KBIL 231653Z ... 17/12 ...` — temperature 17°C, the last routine METAR at/before 231700Z. No stray files in git status.
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 is the 1653Z report. I read it from the Iowa Environmental Mesonet ASOS archive, and it reads: `KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` The temperature group is 17/12, so the temperature is 17. The aviationweather.gov API returned "Invalid value for date" for my one query, so I used only the IEM archive. I did not cross-check a second source. The answer file uses recipe kind "panel" and names the IEM archive as its source. The window and request id are copied from `oracle.json`.

The Iowa Environmental Mesonet ASOS archive (station BIL) gives: `KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` The temperature/dew-point group reads 17/12, so the temperature is 17 °C. I used only that one source. The file uses recipe kind `panel`, and the window and request id are copied from `.imd/reads/oracle.json`. The checker first rejected the window because its keys were in a different order from the brief's. I reordered them to `toBlock`, `fromBlock`, `toBlockHash`, and it then 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 was the 231653Z report. I read it from the Iowa Environmental Mesonet ASOS archive (station KBIL): `KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` The temperature/dew-point group is 17/12, so the temperature is 17. The archive listed no SPECI reports between 15:00 and 18:00 UTC. The reports either side were 231553Z (15/12) and 231753Z (19/11), which fall outside the cutoff or before this one. I used one source only. The file uses recipe kind `panel`, with the chain, block window and closing hash copied from `.imd/reads/oracle.json`.
The answer is 17 °C, and `artifacts/answer.json` passes `check-answer.mjs` (it printed `ok`). The source is the aviationweather.gov data API. The last routine METAR for KBIL at or before 17:00 UTC on 23 September 2026 was the 231653Z report: `METAR KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` The temperature/dew-point group reads 17/12, so the temperature is 17. The next report, 231753Z, falls after 17:00. I only checked that one source, since the task allowed one or two. The recipe kind is `panel`, with that source named. The chain, window and closing hash are copied from `.imd/reads/oracle.json`.
The answer is 17 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints ok for it. The report is the 1653Z METAR for KBIL on 23 September, read from the aviationweather.gov data API: `METAR KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` The next report, 231753Z, falls after 17:00 UTC, so 1653Z is the last one at or before the cutoff. The recipe kind is "panel", with the API URL as the source. The checker rejected my first version because the `window` keys were in a different order from the brief. I reordered them to match `.imd/reads/oracle.json`.
The answer is 17 °C, and `artifacts/answer.json` is written and passes `check-answer.mjs` (it printed `ok`). The last routine METAR for KBIL at or before 17:00 UTC on 23 September 2026 is the 231653Z report. The next routine report, 231753Z, falls after the cutoff. The raw report, from the aviationweather.gov data API, reads: `METAR KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` Its temperature/dew-point group is 17/12, so the temperature is 17. I could not cross-check against a second source. The Iowa Environmental Mesonet archive refused the request as rate-limited, so the answer rests on aviationweather.gov alone. The recipe kind is `panel`, with that API as the source.
The answer is 17 °C, and `artifacts/answer.json` is written; the checker prints `ok`. The last routine METAR at or before 231700Z is the 231653Z report, read from the aviationweather.gov data API: `METAR KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` The temperature/dew-point group reads 17/12, so the temperature is 17. The next routine METAR (231753Z) is after the cutoff, and the 231115Z report is a SPECI, so neither counts. The file uses recipe kind `panel`, with the API URL as the source. The `window` object needed its keys in the order the brief gives (`toBlock`, `fromBlock`, `toBlockHash`) before the checker accepted it.
The answer is 17 °C, and `artifacts/answer.json` is written; the checker prints ok for it. The last routine METAR at or before 231700Z is the 231653Z report, which reads: `KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` The temperature/dew-point group is 17/12, so the temperature is 17 °C. I read it from the Iowa Environmental Mesonet ASOS archive (station KBIL). The reports on either side of it (15:53Z and 17:53Z) fall outside the "at or before 17:00 UTC" cutoff. The recipe is kind "panel" with that archive as the source. The window is copied from `oracle.json`. The first write failed the checker because the window keys were in a different order than the brief's; I reordered them to match.
The answer is 17 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints ok. The last routine METAR at or before 231700Z is the 231653Z report. I read it from the Iowa Environmental Mesonet ASOS archive. The raw report is: `KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` The temperature/dew-point group in the body reads 17/12, so the temperature is 17. The recipe kind is `panel`, with the archive named as the source. I used one source rather than two. The checker first rejected the file because the `window` keys were in the wrong order. I reordered them to match `.imd/reads/oracle.json` exactly.
The answer is 17 °C. `artifacts/answer.json` is written and the checker prints `ok`. The last routine METAR at or before 17:00 UTC is the 231653Z report, from the Iowa Environmental Mesonet ASOS archive: `KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` The temperature group reads 17/12, so the temperature is 17 °C. The recipe kind is `panel` and it names that source. I read only the one source, with no second archive cross-check.
The answer is 17 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints `ok`. The last routine METAR at or before 231700Z is the 231653Z report from KBIL. I read it from the Iowa Environmental Mesonet ASOS archive. The raw report is: `KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` Its temperature/dew-point group is 17/12, so the temperature is 17. The panel recipe names the archive as its source, and the notes quote the raw report. The first check failed because my `window` keys were in the wrong order. The checker wants `toBlock` before `fromBlock`, and I reordered them.
The answer is 17 °C, and `artifacts/answer.json` is written; the checker prints `ok`. The last routine METAR at or before 17:00 UTC is the 1653Z report, from the Iowa Environmental Mesonet ASOS archive (station BIL). The raw report is: `KBIL 231653Z 23010KT 10SM FEW060 SCT100 SCT220 17/12 A3007 RMK AO2 SLP161 T01720117 $` The body's temperature/dew-point group reads 17/12, so the temperature is 17. The T-group in the remarks (T01720117) gives 17.2 °C, but the definition says to use the whole-degree figure from the body. The recipe is kind `panel`, with the archive named as the source. The window, request id and chain are copied from `.imd/reads/oracle.json`.
