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 KEWR (Newark Liberty International Airport, Newark, New Jersey) 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 KEWR (New Jersey) 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 19 °C, and `artifacts/answer.json` is written; the checker prints `ok` for it. The last routine METAR for KEWR at or before 17:00 UTC on 23 September 2026 is the 1651Z report. I read it from the aviationweather.gov data API: `METAR KEWR 231651Z 04018G26KT 10SM BKN036 BKN150 BKN250 19/09 A3045 RMK AO2 PK WND 03031/1603 SLP311 T01890094` The temperature/dew-point group is 19/09, so the temperature is 19. I used a single source. The recipe kind is `panel`, 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 `.imd/reads/oracle.json`. I reordered them to match exactly.
The answer is 19 °C, and `artifacts/answer.json` is written; `check-answer.mjs` prints `ok`. The last routine METAR at or before 17:00 UTC is the 231651Z report. I read it from the aviationweather.gov data API: `METAR KEWR 231651Z 04018G26KT 10SM BKN036 BKN150 BKN250 19/09 A3045 RMK AO2 PK WND 03031/1603 SLP311 T01890094` The temperature/dew-point group is 19/09, so the temperature is 19. The next report, 231751Z, falls after 1700Z. The recipe kind is `panel`, with the source named. The checker rejected the first draft because the `window` keys have to be in the order `oracle.json` uses (`toBlock`, `fromBlock`, `toBlockHash`). I reordered them and it passed.
The answer is **19** °C. It's written to `artifacts/answer.json`, and the checker prints `ok`. - **The report:** the last routine METAR at or before 231700Z was issued at 1651Z: `METAR KEWR 231651Z 04018G26KT 10SM BKN036 BKN150 BKN250 19/09 A3045 RMK AO2 PK WND 03031/1603 SLP311 T01890094`. The temperature/dew-point group is 19/09, so the temperature is 19. - **Sources:** I read it from the aviationweather.gov data API and cross-checked it against the Iowa Environmental Mesonet ASOS archive. Both have the same report. The IEM archive also lists automated readings every 5 minutes; these aren't routine METARs, so I didn't use them. - **Recipe:** kind `panel`, with both sources named. The four definitions are copied from the brief unchanged, and the raw report is quoted in `notes`. The checker first rejected the file because the window's fields weren't in the same order as the brief. I reordered them to match `.imd/reads/oracle.json` and it then passed. The file is left untracked, as required.
The answer is 19 °C, and `artifacts/answer.json` is written and passes `check-answer.mjs` (it printed `ok`). The last routine METAR at or before 231700Z is the 231651Z report from the aviationweather.gov data API: `METAR KEWR 231651Z 04018G26KT 10SM BKN036 BKN150 BKN250 19/09 A3045 RMK AO2 PK WND 03031/1603 SLP311 T01890094` The temperature/dew-point group is `19/09`, so the temperature is 19. I used that one source, and the file uses recipe kind `panel`. 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 19 °C, and `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs` prints `ok` for `artifacts/answer.json`. The last routine METAR at or before 231700Z was issued at 231651Z. The Iowa Environmental Mesonet ASOS archive gives the raw report as: `KEWR 231651Z 04018G26KT 10SM BKN036 BKN150 BKN250 19/09 A3045 RMK AO2 PK WND 03031/1603 SLP311 T01890094` The temperature/dew-point group is 19/09, so the temperature is 19 °C. I used only this one archive. The aviationweather.gov API rejected my date parameter, so I did not read a second source. The first version failed the checker because the `window` keys were in the wrong order. I reordered them to match `.imd/reads/oracle.json`. The file uses the `panel` recipe with the archive named as the source, and the raw report is quoted in `notes`.
The answer is 19 °C, and `artifacts/answer.json` is written; the checker prints `ok`. The last routine METAR at or before 17:00 UTC was issued at 16:51 UTC. I read it from the Iowa Environmental Mesonet ASOS archive (station EWR, routine reports only). The raw report is: `KEWR 231651Z 04018G26KT 10SM BKN036 BKN150 BKN250 19/09 A3045 RMK AO2 PK WND 03031/1603 SLP311 T01890094` The temperature/dew-point group reads 19/09, so the temperature is 19. I used one source and did not cross-check it against aviationweather.gov. The recipe kind is `panel`, with the archive named as the source. The window fields are copied from `.imd/reads/oracle.json`. The checker rejected my first attempt because the window keys were in a different order, so I reordered them to match.
The answer is 19 °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 was the 231651Z report, from the aviationweather.gov data API: `METAR KEWR 231651Z 04018G26KT 10SM BKN036 BKN150 BKN250 19/09 A3045 RMK AO2 PK WND 03031/1603 SLP311 T01890094` The body's temperature/dew-point group reads 19/09, so the temperature is 19. The file uses recipe kind `panel`. The only other report near that hour in the archive output was 231751Z, which is after the cutoff.
The answer is 19 °C, and `artifacts/answer.json` is written. `check-answer.mjs` prints ok for it. The last routine METAR for KEWR at or before 17:00 UTC on 23 September 2026 is the 231651Z report. I read it from the Iowa Environmental Mesonet ASOS archive (station EWR): `KEWR 231651Z 04018G26KT 10SM BKN036 BKN150 BKN250 19/09 A3045 RMK AO2 PK WND 03031/1603 SLP311 T01890094` The temperature group in the body is 19/09, so the temperature is 19 °C. The archive query returned only METAR reports for that period, so there was no SPECI to exclude. The recipe kind is "panel" with that archive named as the source. The window is copied exactly from `oracle.json`. The first checker run rejected the window because the keys were in a different order from `oracle.json`. I reordered them and it passed.
The answer is 19 °C. I wrote it to `artifacts/answer.json`, and `check-answer.mjs` prints `ok`. The last routine METAR for KEWR at or before 17:00 UTC on 23 September 2026 was the 231651Z report, from the Iowa Environmental Mesonet ASOS archive: `KEWR 231651Z 04018G26KT 10SM BKN036 BKN150 BKN250 19/09 A3045 RMK AO2 PK WND 03031/1603 SLP311 T01890094` The temperature/dew-point group reads 19/09, so the temperature is 19. I only pulled this one archive, not a second source. The recipe kind is `panel`, with the archive named as the source. The checker first rejected the window because it expects the keys in the order `toBlock`, `fromBlock`, `toBlockHash`. I reordered them to match `oracle.json`.
The last routine METAR for KEWR at or before 17:00 UTC on 23 September 2026 reported 19 °C. I wrote that to `artifacts/answer.json`, and the checker prints `ok`. The source is the aviationweather.gov data API. The raw report is: `METAR KEWR 231651Z 04018G26KT 10SM BKN036 BKN150 BKN250 19/09 A3045 RMK AO2 PK WND 03031/1603 SLP311 T01890094` It is a METAR, not a SPECI, and 231651Z is the latest observation time at or before 231700Z. The 19 comes from the "19/09" group in the body of the report. The recipe kind is `panel`, with that API URL as its source. Request id, chain and window are copied from `.imd/reads/oracle.json`.
The answer is 19 °C, and `artifacts/answer.json` is written; the checker prints `ok`. The last routine METAR at or before 17:00 UTC is the 231651Z report.
