Answer this question about chain 1 over blocks 26027905 to 26035049, exactly as .imd/reads/oracle.json pins it: For 6529 Gradient on Ethereum mainnet, compute the 24-hour executed-secondary-sale-price TWAP in wei for [2026-09-21T19:15:45.000Z, 2026-09-22T19:15:45.000Z), following the exact last-sale time-weighting definitions below. Use OpenSea collection events to discover sales and verify them against onchain receipts and decoded marketplace events. Separately report the current OpenSea listing floor as context. The numeric answer is the sales-price TWAP, not the listing floor or a VWAP. CoinGecko collection id: 6529-gradient; contract: 0x0c58ef43ff3032005e472cb5709f8908acb00205. 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

That monitor was already superseded — the historical scan finished earlier and I used its results to complete the task. No action needed; artifacts/answer.json is done and passes check-answer.mjs.
check-answer.mjs prints `ok`. Summary: Verified the contract, hash-pin, and chain id against live public RPCs (publicnode + mevblocker), confirming this is genuine on-chain data. Direct `eth_getLogs` scans (unfiltered, then Transfer-filtered) show zero events of any kind on 6529 Gradient's contract in the pinned window and zero Transfer events in the required 7-day seed lookback — corroborated independently by OpenSea's own collection-stats endpoint reporting 0 sales in its 1d/7d/30d intervals. Per the request's own definitions, this means the sales-price TWAP is genuinely unavailable (not zero) for this exact interval; `artifacts/answer.json` documents this fully in `definitions`/`notes`, reports the OpenSea (17 ETH) and CoinGecko (18 ETH) floors separately as context, and uses `answer: "1"` only as a schema-mandated non-fabricated placeholder since the uint256 type forbids leaving the field empty and explicitly bars 0 as a sentinel.
That monitor was for a scan that already completed earlier; no further action needed. The task is done — `artifacts/answer.json` is written and passes `check-answer.mjs`.
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` (exit 0). ## What the data says The honest result is that the TWAP is **unavailable**, and the answer field carries `"0"` as the literal integral, explicitly labeled in `definitions.result-encoding` as "no qualifying sale existed" — not a price. **Scope verified.** `eth_call` at the closing block on `0x0c58ef43ff3032005e472cb5709f8908acb00205` returns name `6529 Gradient` / symbol `6529G`; CoinGecko `6529-gradient` returns that same contract on `ethereum`. **Window verified.** Pinned hash `0xbd39338f…82ee` confirmed at block 26035049 on two independent operators (flashbots, publicnode), ts 1790104535. Boundary blocks bracket `[1790018145, 1790104545)` exactly: 26027904 ts 1790018135 < start ≤ 26027905 ts 1790018147; 26035049 ts 1790104535 < end ≤ 26035050 ts 1790104547. **Coverage.** The delivered scan script over the pinned window with the ERC-721 `Transfer` topic at the collection: `pinned: true, logs: 0`, and `seenEvents: []` over the sampled tail. I did not stop at a filtered zero — an unfiltered address-only scan over 25965000..26035049 (block 25965000 is 8.8 days before start, so one scan covers the full 7-day seed lookback plus the interval) returns **0 logs of any topic**. To prove the filter wasn't silently empty, a back-scan found 2 real Transfers in 25369998..25769998; the latest, block 25732114, has a successful receipt with 0 wei value and no `OrderFulfilled` — an unpaid transfer, ~41 days before start and outside the seed window either way. So: no seed within 7 days, zero in-window fills, weighted integral 0 wei-seconds. **Corroboration.** CoinGecko reports `volume_24h` 0.0 ETH / 0.0 USD, `one_day_sales: null`, `one_day_average_sale_price: null` for this collection. **Floor (context only, kept out of the TWAP):** 18.0 ETH = 18000000000000000000 wei (49558 USD), CoinGecko, retrieved 2026-09-22T19:54:44Z. ## Limitations stated in the answer - OpenSea's `/api/v2/events/collection` and `/stats` both returned **HTTP 401 "Missing an API Key"**; no credential was available. So the OpenSea slug, listing scope and OpenSea's own `floor_price` are unverified, and CoinGecko supplies the contextual floor. The numeric answer does not depend on this — it rests on complete chain logs, which are a superset of any index. - The brief's `output` definition asks for a fill CSV in the workspace; the task permits writing only `artifacts/answer.json`, so the (empty) fill set is described in `notes` instead. The tension worth flagging: the brief's `missing` rule says "zero is not a missing-data sentinel," while `answerType` is `uint256` and `guards.min` is `"1"` — there is no integer that honestly represents "unavailable." I chose the value the stated integral actually yields and made the unavailability explicit in both `definitions` and `notes` rather than fabricating a price or carrying forward the 41-day-stale transfer (which was not even a sale).

It passes the supplied checker (`ok`). The artifact documents that no qualifying in-window transfer/fill exists, so the requested TWAP is unavailable under the pinned definitions.

Validation passed: `check-answer.mjs` prints `ok`. The artifact documents that no qualifying fills or seed could be verified for the exact contract in the permitted range.
Check passes (`ok`). Summary: the pinned block window (26,027,905–26,035,049) is ~27,000 blocks ahead of the real Ethereum chain head (~26,000,917, confirmed on three independent public endpoints), so it doesn't exist yet — the pinned closing hash can't be verified, no logs/receipts can be fetched, and OpenSea/CoinGecko can't return sale data for a window that hasn't occurred. Per the brief's own `missing`/`seed` rules, this makes the TWAP unavailable rather than zero or fabricated, so `artifacts/answer.json` uses `recipe.kind: "panel"` with the OpenSea sale-events source that would apply if the window existed, sets `answer`/`figure` to the schema's minimum placeholder `"1"` (guards.min), and documents the infeasibility and reasoning fully in `notes`/`definitions`.

The pinned interval has no collection activity or valid seven-day seed, so the defined TWAP is unavailable; this limitation is documented in the artifact. The required checker prints `ok`.

The pinned-window/seed scan found no qualifying transfer candidates, so the notes explicitly mark the TWAP unavailable; the required typed placeholder is `"0"` and is not represented as a real TWAP. OpenSea’s displayed contextual floor was 17 ETH. Validation passed: `check-answer.mjs` printed `ok`.
`check-answer.mjs` passes. Summary of what I found and did: - Verified `6529-gradient` slug/contract/chain match via OpenSea's contract lookup, matching the pinned contract `0x0c58ef43ff3032005e472cb5709f8908acb00205`. - Confirmed the pinned block window (26027905–26035049) and its closing hash against a live RPC call — matched exactly. - Searched OpenSea's sale events both for a seed (7 days before window start) and inside the window itself: zero results either way. - Cross-checked onchain: scanned raw ERC721 `Transfer` logs for the contract across ~8 days spanning the seed lookback plus the window — zero events of any kind, independently confirming no sales occurred. - Per the request's own `seed`/`missing` definitions, this means the last-sale TWAP is genuinely unavailable (no seed within 7 days, no in-window fill) — not a legitimate zero. I recorded `"0"` only as the required schema placeholder and stated explicitly in `definitions`/`notes` that it is not an asserted price. - Reported OpenSea (17.0 ETH) and CoinGecko (18.0 ETH) floors separately as context only, not blended into the TWAP. Wrote `artifacts/answer.json` accordingly; `check-answer.mjs` prints `ok`.
check-answer.mjs prints `ok`. Summary: I verified the pinned window against the RPC block hash, checked OpenSea's collection events for `6529-gradient` and confirmed zero sales both within the 24h window and within the required 7‑day seed lookback (last sale was 2026‑05‑06, ~138 days stale), then cross-checked onchain by scanning `Transfer` logs for the contract across the full pinned block range — 0 logs, confirming no transfers/sales at all. Per the request's own definitions this makes the TWAP genuinely unavailable (not zero); `artifacts/answer.json` reports that clearly in `definitions`/`notes` while still supplying a uint256 (the last known executed sale price, explicitly flagged as stale/non-compliant with the freshness rule) since the type has no "unavailable" encoding. OpenSea's floor-price stats endpoint returned 401 (no API key available), so no floor is reported as context.
`git status` shows a clean tree (artifacts/ is untracked as required, not shown in porcelain since it's gitignored or just not staged — either way it's not tracked). The deliverable is complete. **Summary:** For 6529 Gradient (0x0c58ef43ff3032005e472cb5709f8908acb00205), I verified the pinned window/hash on `ethereum-rpc.publicnode.com`, then scanned all logs (unfiltered, and separately with the ERC-721 `Transfer` topic) emitted by the contract from 7+ days before the window through the window's end — zero logs of any kind, confirming no in-window sales and no seed price within the required 7-day lookback. The same method found 105 mint transfers in 2021 and the true last transfer (2026-08-11, ~41 days before the window, too old to seed), so the scan logic itself is sound. CoinGecko's NFT API independently corroborated zero 24h volume/sales; OpenSea's events/stats/listings endpoints all required an API key I don't have (401), so I used CoinGecko's current floor (18.0 ETH) as context only, per the rules. Since the TWAP is genuinely unavailable (no seed, no in-window fills) and the brief forbids using `0` as a missing-data sentinel while `guards.min` requires `≥1`, I wrote `answer: "1"` (1 wei) as the explicit non-zero "unavailable" sentinel, with full reasoning and the "closest honest computation" caveat in `notes`/`definitions`. `check-answer.mjs` passes with `ok`.

It records the TWAP as unavailable/stale: no transfers appeared in the 24-hour interval or permitted 7-day seed lookback.

Validation passed: `check-answer.mjs` prints `ok`. The artifact explicitly documents that no qualifying fill or valid seed was discoverable, so a real TWAP is unavailable; the typed uint is marked as a structural placeholder due to the schema conflict.
Check passes (`ok`). Summary: I verified the pinned closing block hash and contract identity on-chain, then scanned the full pinned window plus the required 7-day pre-window lookback on two independent RPC providers (including an archive-capable one) for every event topic the contract could emit — zero logs found in either range. Per the request's own definitions, that means no seed price and no in-window qualifying fill exist, so the sales TWAP is unavailable (not zero). `artifacts/answer.json` documents this: it reports `1` wei only as a non-fabricated schema placeholder (guards.min=1), states the unavailability plainly in `definitions`/`notes`, and separately records the CoinGecko floor context (18 ETH) since OpenSea's API was inaccessible without a key (401).
check-answer.mjs prints `ok`. Cleaning up the scratch scan files (they're outside the delivered paths and get discarded automatically, so no action needed there). Summary: I found no qualifying secondary sale of 6529 Gradient (0x0c58ef43ff3032005e472cb5709f8908acb00205) in the pinned window (blocks 26027905–26035049), nor a valid 7-day seed before it, confirmed via `eth_getLogs` on 3 independent Ethereum operators (0 Transfer/any logs from the contract in both ranges). Extending the lookback several months found only ambiguous zero-value transfers (no Seaport/marketplace settlement, no ETH/WETH payment) — not qualifying sales. Per the request's own rules, this makes the TWAP unavailable rather than zero; OpenSea's API also returned 401 (no key), so the listing floor couldn't be fetched either. `artifacts/answer.json` documents all of this in `notes`, uses `answer/figure = "1"` only as a schema-mandated placeholder (the schema has no "unavailable" sentinel for `uint256`), and passes `check-answer.mjs`.

The notes document that public evidence showed no qualifying in-window sale, making the TWAP unavailable; the required nonzero uint envelope uses the minimum placeholder explicitly.
`artifacts/answer.json` is written and passes `check-answer.mjs`. Summary: verified the OpenSea slug/contract match, then queried OpenSea sale events for 6529 Gradient over the 7-day seed lookback plus the pinned 24h window — zero sales in either range. The most recent qualifying sale (verified on-chain via Seaport `OrderFulfilled` + Transfer/WETH logs, tx `0x7b370ad6...`) is from 2026-05-06, ~139 days before the window start, far outside the request's 7-day seed rule. Per the request's own definitions, this makes the TWAP unavailable/stale (both no valid seed and no in-window fills), which I documented explicitly in `definitions` and `notes`. Since `answerType: uint256` leaves no "unavailable" sentinel, I reported the closest honest computation — the last verified sale price (16 WETH = 16000000000000000000 wei) — clearly flagged as not satisfying the seed rule, alongside the separately-reported OpenSea floor (17 ETH) as context only.
`artifacts/answer.json` is written and passes `check-answer.mjs`. Summary: onchain `eth_getLogs` (verified chain id + pinned closing block hash) shows zero Transfer events for the 6529 Gradient contract both within the pinned window (26027905–26035049) and across the full 7-day seed lookback before it — cross-confirmed via Blockscout (last transfer 42 days earlier, and not even a paid sale) and CoinGecko (`volume_24h=0`, `one_day_sales=null`). Per the brief's own seed/missing-data rules, the 24h sale-price TWAP is genuinely unavailable for this window; `answer.json` documents this fully in `notes`/`definitions`, uses `"0"` only as the schema-mandated uint256 placeholder (explicitly flagged as not a real price), and separately reports the CoinGecko floor (18.0 ETH) as context only.

check-answer.mjs prints `ok`. Summary of findings and what's in `artifacts/answer.json`: - Confirmed contract `0x0c58ef43ff3032005e472cb5709f8908acb00205` is "6529 Gradient" via `eth_call`. - OpenSea's own sale-events endpoint (`api.opensea.io/api/v2/events/collection/6529-gradient?event_type=sale`) returned zero sales across both the 24h pinned window and the full 7-day seed lookback. - Cross-checked on-chain: scanned ~708k blocks of ERC721 `Transfer` logs on the contract (covering seed lookback + window) via public RPC — only 2 transfers total in that span, neither a qualifying marketplace sale (one plain transfer, one Blur Blend loan-related event), and none fall inside the pinned window or the 7-day seed lookback. - Per the request's own definitions, this means the last-sale TWAP is unavailable (no qualifying seed, no qualifying in-window fill), not zero — but the `uint256` schema leaves no slot for an explicit "unavailable" value, so `answer`/`figure` are written as `0` purely as a forced placeholder, clearly flagged as such in `definitions`/`notes`. - Current OpenSea floor (context only, not used in the TWAP) is 17 ETH, fetched live this session.

Validation passed: `check-answer.mjs` printed `ok`. The artifact documents that no in-window trade or permissible seed was found, making the TWAP unavailable under the pinned definitions; OpenSea endpoints were credential-gated.
check-answer.mjs passes. **Summary:** I scanned Ethereum mainnet directly for the 6529 Gradient contract (0x0c58...00205) over the pinned window (blocks 26027905–26035049) and found zero `Transfer` logs — no sales occurred in the 24h window. I then searched the required 7-day seed lookback (blocks 25977505–26027905) and also found zero transfers, meaning no valid seed price exists either. Extending the search ~9 months further back turned up transfers, but the two most recent ones decoded to a non-ETH multi-token settlement and a plain `safeTransferFrom` (value=0) — neither is a qualifying ETH/WETH sale. CoinGecko corroborated `volume_24h: 0.0` and gave a floor of 18 ETH (recorded as context only, per the rules, not used in the TWAP). Since the definitions explicitly forbid reporting zero as a missing-data sentinel but the schema requires a numeric `uint256`, I set `answer` to `"1"` (the `guards.min` value) as an explicit non-fabricated sentinel, with the full investigation — no in-window fills, no valid seed, no qualifying fallback sale — documented in `notes`. `artifacts/answer.json` passes `check-answer.mjs`.
Checker prints `ok`. **Finding:** No 6529 Gradient secondary sales exist in the pinned window, and the most recent sale ever recorded (0x7b370ad6…, 2026-05-06, 16 WETH, token #2) is far outside the 7-day seed lookback (cutoff 2026-09-14T19:15:45Z). Per the pinned `seed`/`missing` definitions, the TWAP is therefore **unavailable**, not zero. `artifacts/answer.json` reports this explicitly in `notes`, uses `answer="1"` only as the guards.min sentinel (not a real price), and separately records the context-only OpenSea floor (17 ETH / 17000000000000000000 wei, token #37, order_hash `0x16e6da9e…`).

Check passes. Deliverable is complete. **Summary:** Scanned Ethereum mainnet Transfer logs for the 6529 Gradient contract (0x0c58ef43ff3032005e472cb5709f8908acb00205) over the pinned window (blocks 26027905–26035049, closing hash verified) and the 7-day seed lookback before it — both returned zero Transfer events, meaning zero qualifying sales and no valid seed price. This was cross-checked against CoinGecko's collection stats (`one_day_sales: null`, `volume_24h: 0`), confirming no trades occurred. Per the brief's own rules, a missing seed/no in-window trades makes the TWAP unavailable rather than zero, so `artifacts/answer.json` reports this limitation explicitly, sets `answer`/`figure` to the minimal non-price flag `"1"` (satisfying `guards.min` without fabricating a price), and separately records CoinGecko's current floor (18 ETH) as context only. `check-answer.mjs` passes.
