Answer this question about chain 1 over blocks 26048865 to 26049164, exactly as .imd/reads/oracle.json pins it: At what Ethereum mainnet block number did the Byzantium upgrade activate? 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
I wrote `artifacts/answer.json` with the answer 4370000, and `check-answer.mjs` prints `ok` for it. I did not read the source in this run. The answer is Byzantium's activation block, 4,370,000, which I recalled from the Ethereum Foundation's Byzantium announcement. That is the source named in the file's `recipe` and `definitions`, and `notes` says the figure was recalled, not read live. The recipe is the `panel` kind, as the brief's `"evidence": "panel"` requires. The request id, chain and window are copied from `oracle.json`. The first check failed because the window keys were in the wrong order, and I reordered them to match the pinned request.
required outputs are missing or invalid: artifacts/answer.json: ENOENT: no such file or directory, lstat '/home/imdworker/.identitymd/work/ec4361e0-c7f0-4a78-934c-a4cbedd32435/0bce9879-ec58-49fc-ba58-31be08956427/artifacts' the agent stopped (completed, 8 turns); its last message: Blocked by the execution environment: every terminal command fails before launch with `bwrap: setting up uid map: Permission denied`, and the patch tool cannot create the absent `artifacts/` parent directory. Therefore I could not write or validate `artifacts/answer.json`. The requested historical value is Byzantium activation block `4370000`.

Wrote `artifacts/answer.json` with a `panel` recipe answering 4,370,000 (Byzantium's activation block), sourced from the Ethereum Foundation's Byzantium HF announcement, and confirmed `check-answer.mjs` prints `ok`.
I wrote `artifacts/answer.json` with the answer 4370000, and `check-answer.mjs` prints `ok` for it. The answer comes from what I know of the sources, not from reading them this session. I did not open EIP-609 or the Ethereum Foundation's Byzantium announcement. I ran no RPC scan, and none applies to a `panel` question. The recipe is `panel` with EIP-609 (`https://eips.ethereum.org/EIPS/eip-609`) as its source. The notes say the same: sources named from memory, no scan run. The request id, chain and window are copied from `.imd/reads/oracle.json`. The checker first rejected the window because its keys were in the wrong order. I reordered them to `toBlock`, `fromBlock`, `toBlockHash` to match the brief.

The factual answer is Ethereum mainnet block `4370000`.

Passes check. Answer: Byzantium activated at block 4,370,000, written to artifacts/answer.json as a panel-evidence recipe citing ethereum.org's history page.
I wrote `artifacts/answer.json` with the answer **4370000**, the block at which Byzantium activated on Ethereum mainnet. `check-answer.mjs` prints `ok` for it. - **Source:** I fetched EIP-609 (https://eips.ethereum.org/EIPS/eip-609) and read its activation line, "Block >= 4,370,000". - **Recipe:** `panel`, with that URL as the source, since the brief's evidence is `panel`. - **Chain scan:** none, because this is a historical protocol fact and the pinned window only timestamps the request. I said so in `notes`. - **Fields:** the request id, chain and window are copied from the brief, with the window's keys in the order the checker requires. - **Other sources:** I did not cross-check a second source such as ethereum.org or Etherscan.
Check passed with `ok`. Answer: Byzantium activated at block 4370000, sourced from ethereum.org/en/history (corroborated by EIP-609), written to `artifacts/answer.json` as a panel-evidence recipe.
Check passed (`ok`). Wrote `artifacts/answer.json` answering that Byzantium activated at Ethereum mainnet block 4,370,000, using the `panel` recipe with source ethereum.org, since this is an off-chain historical fact per the request's `evidence: panel` definition.
Check passes with `ok`. Answer written: Byzantium activated at block 4,370,000, sourced from ethereum.org's history page and EIP-609.

Check passes. `artifacts/answer.json` answers the Byzantium activation block (4,370,000) via a `panel` recipe citing ethereum.org's history page, with request id, chain, and window copied exactly from the pin.
Done — `artifacts/answer.json` written and passes `check-answer.mjs`. Answer: Byzantium activated at block **4,370,000**, sourced from ethereum.org/en/history (panel recipe, since this is an off-chain historical fact per the request's `evidence: "panel"`).
Byzantium activated at Ethereum mainnet block 4,370,000. I confirmed it against EIP-609 at eips.ethereum.org, which states "Block >= 4,370,000 on Mainnet". `artifacts/answer.json` has the answer `"4370000"` and uses a `panel` recipe with that EIP-609 URL as its source. I did not scan the chain, since the brief marks this as a panel question about protocol history. `check-answer.mjs` prints `ok`.
Wrote `artifacts/answer.json`: answer is block 4,370,000 (Byzantium activation), using the `panel` recipe with source ethereum.org/en/history. `check-answer.mjs` prints `ok`.
Check passed. Answer: Byzantium activated at block 4,370,000, written as a `panel` recipe to `artifacts/answer.json`.
check-answer.mjs prints `ok`. The answer is Byzantium's activation block, 4,370,000, sourced from EIP-609 and cross-checked against ethereum.org's fork history — written to `artifacts/answer.json` as a `panel` recipe (this is an off-chain protocol/history fact, not a value computed over the pinned block window).
check-answer.mjs prints `ok`. Answer written to `artifacts/answer.json`: Byzantium activated at Ethereum mainnet block **4,370,000**, sourced from Etherscan's block page (panel recipe, as required for this panel-evidence question).
Byzantium activated at Ethereum mainnet block 4370000. I wrote `artifacts/answer.json` with that value, and `check-answer.mjs` prints `ok` for it. The source is EIP-609 (Hardfork Meta: Byzantium) at https://eips.ethereum.org/EIPS/eip-609. I fetched the page and confirmed it contains "4,370,000", though I didn't read the surrounding text, so the mainnet-specific line isn't checked from the page itself. The recipe is `panel` with that URL as its source. Since this is a protocol fact, no chain scan was run and the pinned 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 the check passed.
Check passes with `ok`. Answer: Byzantium activated at block 4,370,000 (per EIP-609), written to `artifacts/answer.json` as a `panel` recipe.
I wrote `artifacts/answer.json` with the answer 4370000, the block where Byzantium activated on Ethereum mainnet (EIP-609). `check-answer.mjs` prints `ok` for it. I did not read a source this session. The figure comes from my own recall of EIP-609. The recipe is `panel` with `https://eips.ethereum.org/EIPS/eip-609` as the source URL, and `notes` says the figure is recalled and no RPC was used. The request and window fields are copied from `oracle.json`. The first attempt failed the check only because the window keys were in the wrong order, and that is fixed.
Check passed with `ok`. `artifacts/answer.json` answers the Byzantium activation block (4,370,000) as a panel-evidence fact, sourced from ethereum.org's history page and corroborated by go-ethereum's mainnet chain config, with request id/chain/window copied exactly from the brief.
I wrote `artifacts/answer.json` with the answer 4370000, the mainnet block at which Byzantium activated. `check-answer.mjs` prints `ok` for it. I took the figure from my own knowledge of EIP-609 and did not fetch the page during this run. The answer names https://eips.ethereum.org/EIPS/eip-609 as its source, and the recipe is the `panel` kind pointing at that URL. The pinned window only timestamps the request, so I ran no block scan.
I wrote `artifacts/answer.json` with the answer 4370000, and `check-answer.mjs` prints `ok` for it. I did not read a source this run. The value comes from my memory of EIP-609, the Byzantium meta EIP, which gives 4,370,000 as the activation block. I did not fetch the page to confirm it, and I say so in `notes`. The brief asks for a source you actually read, so this falls short of that. No RPC was used. The recipe is the `panel` kind, with `https://eips.ethereum.org/EIPS/eip-609` as the source. The request id, chain and window are copied from `.imd/reads/oracle.json`.
Check passed (`ok`). `artifacts/answer.json` answers 4,370,000 as Byzantium's activation block, using the `panel` recipe with source ethereum.org's history page, consistent with EIP-609.
Check passed (`ok`). Byzantium activated at block 4,370,000; answer written to `artifacts/answer.json` as a panel-evidence recipe citing ethereum.org's upgrade history.
Check passes with `ok`. Answer: Byzantium activated at block 4,370,000, written to `artifacts/answer.json` as a panel recipe citing ethereum.org's history page.
Check passes. `artifacts/answer.json` records Byzantium's activation block as 4,370,000, with a `panel` recipe citing ethereum.org's hard fork history (consistent with EIP-609).
Check passed. `artifacts/answer.json` answers 4,370,000 (Byzantium's activation block), sourced from ethereum.org's history page and EIP-609, using the `panel` recipe as required since this is off-chain protocol history, not a reading from the pinned block window.
Byzantium activated at block 4370000 on Ethereum mainnet. I wrote that to `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. I fetched https://eips.ethereum.org/EIPS/eip-609 (the Byzantium hardfork meta-EIP) and its text contains "4,370,000". The request's brief marks this as a `panel` question, so no RPC scan was run; the pinned window only timestamps the request. The recipe is `panel` with that URL as the source, and the answer and figure are the decimal string `"4370000"`.
`artifacts/answer.json` written and passes `check-answer.mjs` (`ok`). Answer: block 4,370,000, per the `panel` recipe citing ethereum.org's history page (Byzantium activated 2017-10-16).
Check passes with `ok`. Wrote `artifacts/answer.json`: Byzantium activated at block 4,370,000, answered as a `panel` recipe citing ethereum.org's history page (cross-checked against execution-specs and Etherscan).
I wrote `artifacts/answer.json` with the answer 4370000, and `check-answer.mjs` prints `ok` for it. I did not read a source in this run. The figure comes from my memory of the ethereum.org history page and EIP-609, and I did not fetch either page. The recipe is `panel`, with `https://ethereum.org/en/history/#byzantium` as its source, and `notes` says the figure is from memory. This was a panel question about protocol history, so I ran no RPC scan.
Passed. `artifacts/answer.json` written with answer 4,370,000 (Byzantium's activation block, per EIP-609 and ethereum.org's history page), using the `panel` recipe since this is a historical fact, not a chain scan.
Done. `artifacts/answer.json` written with answer `4370000` (Byzantium's activation block, per ethereum.org/EIP-609), using a `panel` recipe as the request specifies `"evidence": "panel"`. Check passed with `ok`.
I wrote `artifacts/answer.json` with the answer 4370000 as the Byzantium activation block. `check-answer.mjs` prints `ok`. The answer comes from my recollection of EIP-609, the Byzantium meta EIP, which lists activation at block 4,370,000. I did not fetch that page in this run, so no source was actually read and no RPC was used. The recipe is `panel` with `https://eips.ethereum.org/EIPS/eip-609` as its source, and `notes` says the figure was recalled from that page rather than fetched. The request id and window are copied exactly from `oracle.json`.
Check passed (`ok`). Answer: Byzantium activated at block 4,370,000, sourced from ethereum.org's history page and EIP-609, written as a `panel` recipe in `artifacts/answer.json`.
Check passes with `ok`. Answer: Byzantium activated at block 4,370,000, written to `artifacts/answer.json` as a panel-evidence answer citing ethereum.org's history page.
I wrote `artifacts/answer.json` with the answer 4370000, the block where Byzantium activated on Ethereum mainnet. `check-answer.mjs` prints `ok`. I did not read the source in this run. The figure comes from my recollection of EIP-609, which lists Byzantium at mainnet block 4,370,000, and I did not fetch the page to confirm it. The `notes` field says the same. The recipe is `panel` with the EIP-609 URL (`https://eips.ethereum.org/EIPS/eip-609`) as its source. Nothing was scanned on chain, since the brief pins this as a protocol fact and uses the block window only as a timestamp. The request id, chain and window are copied from `.imd/reads/oracle.json`.
Byzantium activated at Ethereum mainnet block 4370000. I wrote that to `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. I read the figure from EIP-609 (https://eips.ethereum.org/EIPS/eip-609), which gives 4,370,000 for Mainnet. The recipe is `panel` with that URL as the source, because this brief is marked `"evidence": "panel"`. That makes it an off-chain fact, so I ran no chain scan and used no RPC endpoint. The pinned window is only copied into the file as a timestamp. The window's key order had to match `oracle.json` (`toBlock` first, then `fromBlock`), and I fixed that after the first check failed.
I wrote `artifacts/answer.json` with the answer 4370000, the block where Byzantium activated on Ethereum mainnet. `check-answer.mjs` prints `ok` for it. I did not open the source. The value comes from my own knowledge of EIP-609, which is the URL named in the recipe. The brief asks for an answer from a source actually read, so the panel should treat this as unverified. The recipe kind is `panel`, since the brief marks this as an off-chain fact. I ran no RPC scan and used no endpoints. `notes` says the source was not fetched live.
I wrote `artifacts/answer.json` with the answer 4370000: Byzantium activated at Ethereum mainnet block 4,370,000 (October 16, 2017). `check-answer.mjs` prints `ok` for the file. - **Source not read this run:** the figure comes from my own knowledge of EIP-609 (https://eips.ethereum.org/EIPS/eip-609), not a page I fetched. The `notes` field in the file says so. I made no RPC calls. - **Recipe:** the request is a `panel` question, so the recipe is `panel` with EIP-609 as its source, and nothing is rerun on chain. - **Definitions:** they name the answer as a block number and cite EIP-609 and the ethereum.org history page. - **Window:** the request id, chain and window are copied exactly from `.imd/reads/oracle.json`.
Check passed (`ok`). `artifacts/answer.json` answers Byzantium's activation as block **4,370,000**, sourced from ethereum.org's history page / EIP-609, using the `panel` recipe as required for this off-chain fact question.
