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 KLAS (Harry Reid International Airport, Las Vegas, Nevada) 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 KLAS (Nevada) 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
Done. `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs` prints `ok` (exit 0). **Answer: 27** (whole °C) — written to `artifacts/answer.json`, left untracked. The selected report: ``` KLAS 231656Z 00000KT 10SM CLR 27/08 A3001 RMK AO2 SLP139 T02720078 ``` Temperature/dew-point body group is `27/08` → **27**. The T-group remark `T02720078` means 27.2 °C, but the requester's definitions pin the body group, so 27 is the answer, not 27.2 and not 28. Why 231656Z is the last routine report at or before 231700Z: the day's feed is a mix of one-minute ASOS records (timestamped `231650Z`, `231655Z`, `231700Z`, `231705Z`, … carrying `RMK T02700080 MADISHF` and `AUTO`) and rotating routine METARs issued at `:56` (`231556Z`, `231656Z`, `231756Z`, carrying `RMK AO2 SLP…`). The latest routine observation time ≤ 231700Z is 231656Z; the next one, 231756Z, is nearly an hour past the cutoff. Sources read, both quoting that same raw text for 231656Z: 1. Iowa Environmental Mesonet ASOS archive, station LAS, 2026-09-23 UTC — the URL in `recipe.source` 2. NOAA/NWS aviationweather.gov data API, METAR KLAS Chain context was only checked, not used: `eth_chainId` = 0x1 and `eth_getBlockByNumber(0x18d856b)` returned `0x779cb990…c1b7` on `ethereum-rpc.publicnode.com`, matching the brief's `toBlockHash`, so the window is exactly the pinned one. One note on the checker: it compares the `window` object by serialized key order, so `fromBlock` before `toBlock` fails even with identical values — the file now lists `toBlock` first, as the brief does.
Recorded the KLAS 1656Z METAR temperature as **27°C** in [artifacts/answer.json](/home/imd/.identitymd/work/014c84cf-4d86-489f-8981-b031ecc1e9f9/ddb88c62-d680-4329-abc0-7281e7022a1b/artifacts/answer.json).

It's in `artifacts/answer.json`, and the checker prints `ok`. - **The report:** the last routine METAR at or before 17:00 UTC was `METAR KLAS 231656Z 00000KT 10SM CLR 27/08 A3001 RMK AO2 SLP139 T02720078`. The temperature/dew-point group is `27/08`, so the temperature is 27 °C. - **Sources:** the Iowa Environmental Mesonet ASOS archive and the aviationweather.gov data API both returned the same text for this report. The IEM archive shows no SPECI (special report) between 16:56Z and 17:00Z. - **Recipe:** kind `panel`, naming both sources. The notes quote the raw report, and the requester's four definitions are copied in unchanged. The checker's first run failed because the `window` keys weren't in the same order as in `oracle.json`. I reordered them and the second run passed.
Checker passes. The answer is 27°C, from KLAS METAR 231656Z (`27/08`), sourced via the Iowa Environmental Mesonet ASOS archive — `artifacts/answer.json` is written and validated.
The answer is 27 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints ok. The last routine METAR at or before 231700Z is the 231656Z report: `KLAS 231656Z 00000KT 10SM CLR 27/08 A3001 RMK AO2 SLP139 T02720078` The next report is 231756Z, which is after the cutoff. I read it from the Iowa Environmental Mesonet ASOS archive (station LAS, METAR and SPECI report types requested for 23 September UTC). I didn't cross-check a second source. The aviationweather.gov query I tried rejected my date format, so I didn't use it. The recipe kind is `panel`, with that archive query as the source. The request id, chain and window match `oracle.json`. The checker rejected my first draft only because the window keys were in a different order, and I reordered them.
The answer is 27 °C, and `artifacts/answer.json` is written. `check-answer.mjs` printed `ok` after I reordered the window keys to match the brief. It had rejected the first version for key order. The last routine METAR at or before 17:00 UTC is the 1656Z report. Both the Iowa Environmental Mesonet ASOS archive (station LAS) and the aviationweather.gov data API show the same text: `KLAS 231656Z 00000KT 10SM CLR 27/08 A3001 RMK AO2 SLP139 T02720078` The temperature/dew-point group reads 27/08, so the answer is 27. The recipe is kind `panel`, with the two sources named. The next report, 1756Z, is after the cutoff. No SPECI was involved.
`artifacts/answer.json` is written with an answer of 27, and `check-answer.mjs` prints ok for it. - **Source:** the aviationweather.gov data API. - **Report used:** the 1656Z observation on 23 September, the last routine METAR at or before 17:00 UTC. The raw text is `METAR KLAS 231656Z 00000KT 10SM CLR 27/08 A3001 RMK AO2 SLP139 T02720078`, so the temperature group is 27/08. - **Recipe:** kind "panel" with that source. The request id, chain and window are copied exactly from `oracle.json`, including its key order, which the checker requires. I only checked one source, not two, and did not cross-check against another archive.
The answer is 27 °C, and `artifacts/answer.json` is written and passes the checker (`ok`). The report is the routine METAR for KLAS with observation time 231656Z, read from the aviationweather.gov data API: `METAR KLAS 231656Z 00000KT 10SM CLR 27/08 A3001 RMK AO2 SLP139 T02720078` Its temperature/dew-point group is 27/08, so the temperature is 27. The next report, 231756Z, falls after 17:00 UTC, so 231656Z is the last one at or before it. The recipe kind is `panel`, with the aviationweather.gov query URL as the source. I used that one source only. The first write failed the checker because the window keys were in the wrong order (`fromBlock` before `toBlock`). I reordered them to match `oracle.json` and the check then passed.
The answer is 27 °C. I wrote it to `artifacts/answer.json`, and `check-answer.mjs` prints `ok`. The last routine METAR at or before 17:00 UTC is the 231656Z report. The Iowa Environmental Mesonet ASOS archive (station LAS) gives its raw text as: `KLAS 231656Z 00000KT 10SM CLR 27/08 A3001 RMK AO2 SLP139 T02720078` The temperature group in the body reads 27/08. The recipe kind is `panel`, and the source named in it is that archive. I read only the Iowa Environmental Mesonet archive, not a second source. The first checker run rejected the window because its keys were in a different order than in `oracle.json`. I reordered them, and the values were already correct.
I wrote `artifacts/answer.json` with an answer of 27 °C, and `check-answer.mjs` prints ok for it. The raw report, read from the aviationweather.gov data API, is: `METAR KLAS 231656Z 00000KT 10SM CLR 27/08 A3001 RMK AO2 SLP139 T02720078` The next report is 231756Z, which falls after 17:00 UTC. The 231656Z report is type METAR (not SPECI) and has the latest observation time at or before 231700Z. Its body group reads 27/08, so the temperature is 27. I used the `panel` recipe with the API URL as the source. I read only that one source and did not cross-check it against a second archive. The first check failed because the `window` keys were in the wrong order, so I reordered them to match `oracle.json` exactly.
I wrote `artifacts/answer.json` with the answer 27, and `check-answer.mjs` prints `ok` for it. The last routine METAR at or before 17:00 UTC on 23 September is the 231656Z report. I read it from the aviationweather.gov data API: `METAR KLAS 231656Z 00000KT 10SM CLR 27/08 A3001 RMK AO2 SLP139 T02720078` The temperature group is 27/08, so the air temperature is 27 °C. The T-group in the remarks (27.2) agrees. I used only that one source. The checker first rejected the `window` object because its keys were in a different order from `oracle.json`. I reordered them and it passed. The recipe is kind `panel` with the API URL as its source, and the notes quote the raw report.
The answer is 27 °C, and `artifacts/answer.json` passes `check-answer.mjs` (it printed `ok`). The last routine METAR for KLAS at or before 17:00 UTC on 23 September 2026 is the 1656Z report. I read it from the Iowa Environmental Mesonet ASOS archive (station LAS, report type METAR): `METAR KLAS 231656Z 00000KT 10SM CLR 27/08 A3001 RMK AO2 SLP139 T02720078` The temperature/dew-point group is 27/08, so the temperature is 27. The file uses recipe kind `panel` and names that source. It has the request id, chain and window copied from `.imd/reads/oracle.json`. The checker first rejected the window because the keys were in a different order than the brief's (`toBlock` before `fromBlock`), so I reordered them. I only used the IEM archive. The aviationweather.gov query I also ran returned only the most recent observations, not the 23 September ones.
The answer is 27 °C, and `artifacts/answer.json` is written; the checker prints `ok` for it. The last routine METAR for KLAS at or before 231700Z is the 231656Z report, read from the aviationweather.gov data API: `METAR KLAS 231656Z 00000KT 10SM CLR 27/08 A3001 RMK AO2 SLP139 T02720078` The body group `27/08` gives a temperature of 27 °C. The next report, 231756Z, is after the cutoff. The listing I read showed only routine METARs, so there was no SPECI to rule out. The recipe kind is `panel`, with the aviationweather.gov query as its source.
