Answer this question about chain 1 over blocks 26047886 to 26048184, exactly as .imd/reads/oracle.json pins it: In what year did Bitcoin's first block subsidy halving happen? Write only artifacts/answer.json: the typed answer (uint256) and the recipe that reproduces it.
VERDICT: paths and tree verified; no suite was run for this kind of work

The checker prints `ok`. The pinned brief defines this as an off-chain Bitcoin history fact and says the Ethereum window only timestamps the request, so the year cannot be computed from that block range or reproduced from Ethereum RPC data alone.

This is the only source I read. My first fetch attempts of the Bitcoin wiki pages returned nothing. The recipe is `panel`, with the Blockstream block-height URL as its source. It touches no chain data, so no RPC endpoints were used, and `definitions` and `notes` state the year definition and the source.

The check passes.

I wrote `artifacts/answer.json` with the answer 2012, and `check-answer.mjs` prints `ok` on it. Bitcoin's first halving was at block 210000, which is the first block paying the 25 BTC subsidy. The Blockstream API gives that block's timestamp as 1354116278, which is 28 November 2012 UTC. The Wikipedia Bitcoin protocol page also says the reward dropped to 25 in late 2012. The recipe is `panel`, with the Blockstream block-height URL as its source. Nothing was scanned on Ethereum, since the request says the pinned window only timestamps it. The first version failed the check because the `window` keys were in the wrong order. I reordered them to match `oracle.json`.

I fetched the Bitcoin wiki's "Controlled supply" page and only confirmed it mentions 2012. I did not read the halving date or the block number from the page. Those come from my own knowledge, and the answer cites that page as its source. The recipe is `panel`, as the brief requires for an off-chain fact. I used no RPC endpoint and ran no scan. The pinned window is copied into the file only as a timestamp. The first check failed because the window keys were in the wrong order (`fromBlock` before `toBlock`).

Bitcoin's first block subsidy halving happened in 2012, and I wrote that to `artifacts/answer.json`. `check-answer.mjs` prints `ok` for it. The halving happened at block 210000. I read that block from the Blockstream API; its timestamp is 1354116278, which is 28 November 2012 UTC. The recipe is a `panel` recipe pointing at that Blockstream URL. No chain scan was run, since the question is about Bitcoin and the pinned Ethereum window only timestamps the request. My first attempts to read the Bitcoin wiki returned nothing usable, so Blockstream is the only source I read.
Check passed. `artifacts/answer.json` is written with answer `2012` (panel recipe citing the Bitcoin Wiki's Controlled Supply page), and `check-answer.mjs` prints `ok`.
Check passes. Answer: Bitcoin's first halving occurred in **2012** (block 210,000, 2012-11-28 UTC), written to `artifacts/answer.json` as a panel-evidence recipe citing the Bitcoin Wiki's "Controlled supply" page.
Check passes with `ok`. `artifacts/answer.json` answers 2012 (Bitcoin's first halving at block 210000, 2012-11-28) using the `panel` recipe, citing the Bitcoin wiki as source, since this is off-chain historical fact evidence.
I wrote `artifacts/answer.json` with the answer **2012**, and `check-answer.mjs` prints `ok` for it. The first halving is block 210000, where the subsidy went from 50 to 25 BTC. I read that block from the Blockstream explorer API. Its timestamp is 1354116278, which is 2012-11-28 15:24:38 UTC. The recipe is `panel`, with the Blockstream block URL as its source. No Ethereum RPC or scan was used, because the brief says the pinned window only timestamps the request. The window and request id are copied from the brief. The definitions state the UTC calendar-year reading and name the source. My first version failed the check because the `window` keys were in a different order from the brief; I reordered them to match.
Bitcoin's first halving happened in **2012**, so `artifacts/answer.json` carries the answer "2012". The check script `check-answer.mjs` prints `ok` for it. I fetched the Bitcoin wiki's Controlled supply page (https://en.bitcoin.it/wiki/Controlled_supply) and found the date 2012-11-28 on it. That is block 210000, where the subsidy went from 50 to 25 BTC. The page is the `panel` recipe's source, and this is a panel question, so no chain scan was run. The Ethereum window only timestamps the request. The first version of the file failed the check because the `window` keys were in the wrong order. I reordered them to match `oracle.json`, and it now passes.
I wrote `artifacts/answer.json` with the answer `"2012"`. `check-answer.mjs` prints `ok` for it. Bitcoin's first subsidy halving was at block 210000, on 28 November 2012, when the reward dropped from 50 to 25 BTC. I answered this from my own knowledge of Bitcoin's history. I did not open the source page during this run, so I haven't checked the date against it. The `notes` field says the same. The recipe is `panel`, with the source given as https://en.bitcoin.it/wiki/Controlled_supply (the Bitcoin wiki). No RPC endpoint or Ethereum data was used, since the request says the pinned window only timestamps the question. The check first failed because the `window` keys were in a different order from `oracle.json` (`toBlock` before `fromBlock`). I reordered them and it then passed.
Check passed. `artifacts/answer.json` answers 2012 (Bitcoin's first halving, block 210000, 2012-11-28 UTC) via the `panel` recipe citing the Bitcoin wiki's Controlled Supply page, with request id, chain, and window copied exactly from the pin.
Check passes. `artifacts/answer.json` written with answer `2012` (first Bitcoin halving, block 210000, 2012-11-28 UTC), using the `panel` recipe citing the Bitcoin wiki's Controlled Supply page, and `check-answer.mjs` prints `ok`.
I wrote `artifacts/answer.json` with the answer `"2012"`: Bitcoin's first halving, at block 210000, was on 2012-11-28. `check-answer.mjs` prints `ok` for the file. - **Source:** the Bitcoin wiki's Controlled supply page (`https://en.bitcoin.it/wiki/Controlled_supply`), whose table lists the first halving as 2012-11-28. I fetched that page during the run. - **Block check:** I also checked that block 210000 exists on blockstream.info. - **Recipe:** the recipe kind is `panel` with that URL as the source, since the brief says `"evidence": "panel"`. No scan was run, because this question has no chain data to compute over. - **Window:** the pinned Ethereum window is copied exactly from `oracle.json` and only timestamps the request. I did not confirm the halving date on a second independent source.
Check passed with `ok`. Answer: Bitcoin's first halving occurred in 2012 (block 210000, 2012-11-28), written to `artifacts/answer.json` as a `panel` recipe citing the Bitcoin wiki's Controlled Supply page.

Check passed. `artifacts/answer.json` is written with answer 2012, using the `panel` recipe sourced from the Bitcoin wiki's Controlled Supply page.
I've written `artifacts/answer.json` with the answer **2012**, and the answer check prints `ok`. - **Source:** The Bitcoin wiki's "Controlled supply" page (https://en.bitcoin.it/wiki/Controlled_supply) says the block reward first dropped from 50 to 25 BTC at block 210000, on 2012-11-28. That URL is the `panel` recipe's `source`. - **Cross-check:** The Blockstream explorer shows block 210000 was mined at 2012-11-28T15:24:38 UTC, so the year in UTC is 2012. - **Window:** The request id, chain and window are copied from `oracle.json`. As the brief says, the pinned Ethereum blocks only timestamp the request, so I made no Ethereum RPC calls. The definitions and notes in the file say which block counts as the halving and what I read.
I wrote `artifacts/answer.json` with the answer `2012`, and `check-answer.mjs` prints `ok` for it. Bitcoin's first halving (50 to 25 BTC) happened at block 210000 on 28 November 2012. That is from my own knowledge. I did not fetch or read any source during this run, and the file says so under `definitions.source` and in `notes`. The recipe is `panel` with the source URL `https://en.bitcoin.it/wiki/Halving`, which is where the fact can be checked. The brief says the Ethereum window only timestamps the request, so I ran no chain scan and used no RPC endpoint. My first draft had the `window` keys in a different order than the brief. The check rejected it, and I reordered them to match.
I wrote `artifacts/answer.json` with the answer 2012, and `check-answer.mjs` prints `ok`. I answered from memory and did not open the source in this run. The first halving was at block 210000 on 2012-11-28 (UTC). The recipe is the `panel` kind, citing https://en.bitcoin.it/wiki/Controlled_supply as its source. The `notes` field says the fact comes from my own knowledge of that page and that no RPC was used. The check first failed because the `window` keys have to be in the order `toBlock`, `fromBlock`, `toBlockHash`. I reordered them to match `oracle.json`.
I wrote `artifacts/answer.json` with the answer 2012, and `check-answer.mjs` prints `ok` for it. The first Bitcoin halving happened at block 210,000, which was mined on 28 November 2012. I gave that from memory of the Bitcoin wiki "Controlled supply" page (`https://en.bitcoin.it/wiki/Controlled_supply`), which is the `panel` recipe's source. I did not fetch the page during this run, and `notes` says so. The Ethereum block window and closing hash are copied exactly from the brief. It only timestamps the request; no chain scan was run, since this is a panel question.

The recipe is `panel`, with the Bitcoin wiki's Controlled supply page (https://en.bitcoin.it/wiki/Controlled_supply) as the source. I did not read that page during this run. The date is from memory, and the `notes` field says so. No RPC was used, since the question is about Bitcoin's history and the pinned Ethereum window only timestamps it.
