Answer this question about chain 1 over blocks 26021169 to 26021466, exactly as .imd/reads/oracle.json pins it: Does the Lil Pudgys NFT contract report a totalSupply() of at least 20,000 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
Created and validated `artifacts/answer.json`, left untracked. Answer: **true**. At closing block `26021466`, `totalSupply()` returned **21,931**, confirmed by two public RPC endpoints matching the pinned block hash.
Created `artifacts/answer.json` with answer `true`: totalSupply was **21,931** at block **26,021,466**. Verified against three public RPC operators and validated the JSON and recipe.
Task complete. I verified the pinned block (26021466) and closing hash matched on two independently-operated public Ethereum RPCs (publicnode.com and mevblocker.io), both returning `totalSupply() = 21931` for the Lil Pudgys contract — which is ≥ 20,000, so the answer is `true`. Wrote `artifacts/answer.json` with the `call-compare` recipe, matching request id/chain/window, and noted the endpoints used plus the third endpoint (flashbots) that was skipped since it refused `eth_call`.
Created and validated [artifacts/answer.json](/root/.identitymd/work/fa0d8bdb-e17f-441b-a251-6dbc0ad4c06a/359068b7-960b-4c39-a4a3-e4b2e7e03d06/artifacts/answer.json). Answer: `true` — `totalSupply()` returned `21,931` at block `26021466`, confirmed through two independent public RPC operators.
**Answer: `true`** — `totalSupply()` = **21931** ≥ 20000. What I did: - **Recipe**: `call-compare` on `0x524cab2ec69124574082676e6f654a18df49a048`, `function totalSupply() view returns (uint256)`, no args, `>=` `20000` — exactly the catalogue's parameters, nothing extra. - **Computed it over the pinned window**: `eth_call` (selector `0x18160ddd`) at the closing block 26021466 returned `0x…55ab` = 21931. The opening block 26021169 also returned 21931, so supply didn't move inside the window. - **Cross-checked across three operators**, each verified first on `eth_chainId` = `0x1` and on the pinned closing hash `0x9cc4786d…f917ac`: publicnode, valve.city, nodereal. All three agreed on 21931. Flashbots matched on the block hash but refuses `eth_call` ("rpc method is not whitelisted"), so it isn't counted as a cross-check. - **Contract identity confirmed on chain** at the closing block: `name()` = `LilPudgys`, `symbol()` = `LP`. - **Definitions** state the contract, the call and block used, the comparison (20000 as a plain token count, unscaled — ERC-721 supply counts tokens), and what `figure` is. `artifacts/answer.json` is written and left untracked (the path is gitignored here); no other file was touched. Validated: valid JSON, requestId/chainId/window byte-identical to `.imd/reads/oracle.json`, `answerType` `bool` with a real boolean answer, lowercase address and hash.
**Answer: `true`** — Lil Pudgys `totalSupply()` is **21931** at block 26021466, which is ≥ 20,000. **Produced:** `artifacts/answer.json` (only that path was written; left untracked — `artifacts/` is in `.git/info/exclude`). Working tree otherwise clean; no config, `lib/`, or `.github/` files touched. **How it was computed.** The question is a single state read at the closing block, so the catalogue's `call-compare` recipe fits exactly: `to` = `0x524cab2ec69124574082676e6f654a18df49a048`, `function` = `function totalSupply() view returns (uint256)`, `args` = `[]`, `op` = `>=`, `threshold` = `20000`. No `eth_getLogs` scan was needed, so none of the truncation hazards in the RPC skill applied. **Verification.** - `eth_chainId` returned `1` and block 26021466 hashed to `0x9cc4786d81fa7b1b57212ee78a02b66c8b60d8ff0bb822825e87cafc96f917ac` — the pinned `toBlockHash` — on every endpoint used. - Contract identity confirmed on chain: `name()` = `"LilPudgys"`, `symbol()` = `"LP"`. - `totalSupply()` at the pinned closing block returned **21931** on three independent operators — publicnode, mevblocker, valve.city — via `cast`, and again via raw `eth_call` (`0x18160ddd` at `0x18d0e5a` → `0x55ab` = 21931) on the same three. - Consistency check: supply is flat at 21931 across the whole window (opening block 26021169 reads the same), so the answer doesn't depend on where inside the window it's read. - A script in `test/scratch/` asserts the file is valid JSON, that `requestId`/`chainId`/`window` are byte-identical to `.imd/reads/oracle.json`, that `answer` is a real JSON bool matching `figure` vs the threshold, and that `recipe` carries exactly the `call-compare` parameters and nothing else. All checks pass. **Worth flagging for the reviewer.** `https://rpc.flashbots.net/fast` is first in the chain-1 row but does not whitelist `eth_call` (403, "rpc method is not whitelisted"), so it served only the chain-id and block-hash checks and was then dropped per the rotation rules. `ethereum-rpc.publicnode.com` serves the closing block but refuses the opening block as an archive request; that affects only the supplementary flat-supply check, not the answer. Both are named in `notes`. I also caught and fixed a wrong hex block tag I had written into the `blockTag` definition — the file now reads `0x18d0e5a`, verified to decode to 26021466.

`artifacts/answer.json` is written and is valid JSON. The answer is **true**: `totalSupply()` on Lil Pudgys was 21931 at the closing block 26021466, which is at least 20,000. - **Check on the endpoints:** three independent public endpoints returned the same value (`0x55ab`, i.e. 21931): `ethereum-rpc.publicnode.com`, `one.valve.city` and `rpc.mevblocker.io`. Each reported chain id 1 and block hash `0x9cc4…17ac`, matching the pinned closing hash. - **Flashbots:** `rpc.flashbots.net/fast` matched on chain id and block hash but refuses `eth_call`, so I did not use it for the figure. - **Recipe:** it uses the `call-compare` kind from the catalogue, with `>=` and a threshold of 20000. - **Not run:** I did not run the recipe through any separate tool. The check was the direct `eth_call` reads above. The file is untracked, as required.
Created and validated `artifacts/answer.json`. Answer: **true** — `totalSupply()` was **21,931** at the pinned closing block, confirmed by four public RPC endpoints.
