Answer this question about chain 1 over blocks 26021170 to 26021467, exactly as .imd/reads/oracle.json pins it: Does the VeeFriends NFT contract report a totalSupply() of at least 10,255 at the closing block of the pinned window? Write only artifacts/answer.json: the typed answer (bool) and the recipe that reproduces it.
VERDICT: paths and tree verified; no suite was run for this kind of work
Done. `artifacts/answer.json` is written (untracked/ignored, as required for the daemon to pick up). **Answer: `true`** — VeeFriends (`0xa3aee8bce55beea1951ef834b99f3ac60d1abeeb`) reports `totalSupply() = 10255` at block 26021467, which meets the `>= 10255` threshold exactly. How it was verified: - `eth_chainId` = `0x1` and the hash of block `0x18d0cdb` equals the pinned `toBlockHash` on flashbots, publicnode, and mevblocker. - `eth_call` with selector `0x18160ddd` at that block returned `0x…280f` (10255) on three independent operators: **mevblocker**, **valve.city**, and **nodereal**. - flashbots (eth_call not whitelisted), publicnode (archive calls need a token), and bloxroute (historical state unavailable) couldn't serve the call — none contradicted the value. All of this is recorded in `notes`. Recipe is `call-compare` with exactly the catalogue's parameters (`to`, `function`, `args`, `op`, `threshold`); `figure` is `"10255"`. One note worth flagging: the value sits precisely on the threshold, so the outcome hinges entirely on the request's `>=` comparison — any panel member using `>` would land on `false`. I added a `closingBlock` definition making explicit that the call is at `toBlock` and `fromBlock` doesn't affect a point-in-time read.
**Answer: `true`** — VeeFriends `totalSupply()` at block 26021467 is exactly 10255, so `>= 10255` holds. **Deliverable:** `artifacts/answer.json` (untracked, as required — the repo gitignores `artifacts/`). **How it was computed and verified** - Single historical `eth_call` of `totalSupply()` (`0x18160ddd`) on `0xa3aee8bce55beea1951ef834b99f3ac60d1abeeb` at block `26021467`. Raw return `0x…280f` = **10255**. - Cross-checked on two endpoints from two operators — `rpc.mevblocker.io/fast` and `one.valve.city/rpc/vk_demo/evm/1` — identical word from both. `eth_chainId` = `0x1` on each, and `eth_getBlockByNumber(0x18d0e5b)` returned `0xedab4514…d4f77`, matching the pinned `toBlockHash`. - Contract identity confirmed on both: `name()` = "VeeFriends", `symbol()` = "VFT". - Stability check: `totalSupply()` at the opening block 26021170 is also 10255, so nothing moved inside the window and the result isn't sensitive to block off-by-one. **Worth flagging for the rerunner:** the closing block was ~150 blocks behind head at run time, past the 128-block state window of non-archive nodes. Three of the six listed mainnet endpoints confirmed the pinned block hash but refused the historical call: `rpc.flashbots.net/fast` (`eth_call` not whitelisted), `ethereum-rpc.publicnode.com` (archive needs a token), `virginia.rpc.blxrbdn.com` (historical state unavailable). Reproducing this recipe requires an archive-capable endpoint. **Recipe:** `call-compare` with exactly `to`, `function`, `args`, `op`, `threshold` — no extra fields; the run details live in `notes`. Open points (integer reading of "10,255", no decimal scaling, evaluation at the closing block only) are stated under `definitions`. **Not done deliberately:** nothing else was written or modified — no log scan was needed, and `test/scratch/` was unused since the check is two RPC calls.
`artifacts/answer.json` is written and validated. **Result: `true`** — VeeFriends `totalSupply()` at block 26021467 is `0x…280f` = **10255**, and 10255 ≥ 10255. What I did: - Confirmed the pinned closing hash `0xedab45…d4f77` for block 26021467 (and the opening block 26021170 → `0x7d0ef1…c827`) on three endpoints; all reported `eth_chainId` `0x1`. - The window's close is now >128 blocks behind head, so the non-archive endpoints refused the state (publicnode: "Archive requests require a personal token"; blxrbdn: "historical state … is not available"; flashbots doesn't whitelist `eth_call`). Six archive-capable endpoints from six distinct operators — drpc, tenderly, valve.city, 1rpc, nodereal, merkle — all returned `10255`. - Repeated the call with the block parameter as `{blockHash: <pinned hash>}` on three of them, so the read is bound to the pinned block, not just a height. - Sanity checks: `eth_getCode` at the closing block returns 19689 bytes, `name()` returns `VeeFriends`, and the same call at the opening block also returns 10255 (supply unchanged across the window). The recipe is `call-compare` with exactly its catalogue parameters (`to`, `function`, `args`, `op`, `threshold`); endpoints and method live in `notes`. `definitions` restates the request's three and adds the four it left open: evaluation block, threshold reading of "10,255", equality counting as "at least", and the state basis (canonical post-state, no overrides). `figure` is `"10255"`. The file is untracked and not force-added; note `git status` itself can't run here — the sandbox denies reading `/home/seat/.gitconfig`.
Created `artifacts/answer.json` with answer **true**: closing-block `totalSupply()` was **10,255**. Verified against two independent public RPC operators and validated the JSON and recipe.
Created artifacts/answer.json with answer `true`: totalSupply() was exactly **10,255** at block **26,021,467**. Three public RPC operators agreed. Validated the JSON, pinned fields, and reproduction recipe.
The answer is **true**: at block 26021467, `totalSupply()` on VeeFriends (`0xa3aee8bce55beea1951ef834b99f3ac60d1abeeb`) returns exactly 10255 (`0x280f`). That sits on the threshold, so `>= 10255` holds. - **Cross-check:** five independent operators returned the same value: publicnode, mevblocker, nodereal, blxrbdn and valve.city. Each reported chain id 1 and the pinned closing hash `0xedab4514…7086e77d4f77`. The flashbots endpoint confirmed the hash but doesn't allow `eth_call`, so I didn't use it for the value. - **Recipe:** I used `call-compare` with `function totalSupply() view returns (uint256)`, empty args, op `>=` and threshold `"10255"`. I wrote the threshold as a decimal string, following the uint256 convention. The catalogue doesn't say whether it should be a string or a number, so that is a guess. - **Deliverable:** `artifacts/answer.json` parses as valid JSON and copies the request id, chain and window from `oracle.json`. The endpoints used are named in `notes`. It's untracked and no other paths were touched.
Created `artifacts/answer.json` with answer `true` and the reproducible recipe. Four public RPC endpoints confirmed `totalSupply() = 10255` at the pinned closing block. JSON validation passed; the file was left untracked.
`artifacts/answer.json` is written and parses as valid JSON. The answer is **true**: `totalSupply()` at block 26021467 is exactly 10255 (`0x280f`), which meets the `>=` 10255 threshold. Three independent public endpoints returned that value: `ethereum-rpc.publicnode.com`, `rpc.mevblocker.io/fast` and `one.valve.city/rpc/vk_demo/evm/1`. Each reported chain id 1 and the pinned closing block hash. `rpc.flashbots.net/fast` matched the hash too but doesn't allow `eth_call`, so I didn't use it for the value. The recipe is `call-compare` on `0xa3aee8bce55beea1951ef834b99f3ac60d1abeeb` with `function totalSupply() view returns (uint256)`, `op` `>=` and threshold `10255`. Because the supply equals the threshold, the answer is sensitive to the exact block used, so `definitions` and `notes` both record that. I ran no scripts or scratch tests; the check was the three direct RPC calls plus the JSON validation.
