> FETCHING JOB RECORD

I'll start by reading the task inputs.Now I understand the task. This is a panel-evidence NFT TWAP question for Boo Bears on mainnet. Let me set up a plan and start verifying the environment.imd-rpc works. Let me verify the pinned blocks and scan for the contract's events in the window.Zero logs at all from the contract in the window — no transfers or sales in the 24h. Let me verify activity exists at all by scanning the 7-day seed window and checking block timestamps/hash.100k block cap. Let me scan backward in chunks to find the contract's most recent activity.The contract's last activity was ~452k blocks ago (~63 days) — zero logs in-window and none in the 7-day seed range. Before concluding, let me verify the collection scope via CoinGecko and try the OpenSea API.The last-ever activity was ~63 days ago. Let me check the OpenSea collection slug that returned 200 — verify it's the same contract.Slug verified: OpenSea `boo-bears` = contract 0x2c88...1146. Let me try the stats endpoint for the floor (context only).OpenSea stats (public): boo-bears = this contract, 0 sales in 1d/7d/30d, floor_price 0.0. Let me verify the one missing chunk of history and inspect the last-ever transfer's receipt.That last interaction was the NFT moving *into* a contract while the sender paid 0.685 ETH — a deposit, not a sale. The real last sale is further back. Let me try Reservoir's public sales API for discovery, then verify onchain.Reservoir is unreachable. Chain data is definitive anyway — let me walk backward through the contract's Transfer history to find the last actual sale.Ethplorer doesn't track ERC721 ops. Let me try LooksRare's public API and keep scanning backward in parallel.LooksRare API is gone. Let me confirm the pinned block hash and window timestamps precisely, then continue the backward scan for the last real sale.Only 2 transfers in 23M-25.58M, both token 194. Let me continue scanning to deployment and check what 0x7591 is.That looks like a marketplace sale — token 194 moved plus an ERC20 transfer of ~6.57e18. Let me get the full log details to identify the payment token.The payment token there is `0x0000000000a39bb272e79075ade125fd351887ac` — not ETH/WETH, so that sale wouldn't qualify anyway. Let me identify it and check the backward scan progress.Full history: 1894 transfers, earliest at block 13514960. The Blur Pool token (name "Blur Pool") paid that last sale — not literal ETH/WETH. Let me fetch receipts for the most recent ~25 distinct transfer txs and detect which had ETH/WETH payments.Timed out. Let me rerun with progress visible and a longer window.Those were batch migrations (no payment logs). Let me check the dump progress.Those recent moves were all migrations/deposits — no ETH/WETH payments. Let me check the history dump progress.The public endpoints are too slow. Let me kill this and use imd-rpc (the private archive node) instead — it answered 100k chunks in seconds.It's collecting transfers (1107 so far). Let me wait for completion.All 1894 historical transfers collected. Let me analyze the newest-first for sale candidates.Let me extend the checker to flag any payment evidence and run it over the ~60 newest distinct txs.All recent moves are staking deposits (fee ~0.007-0.012 ETH) or migrations — no sales. Let me classify the next batch of older txs.Found it — the last literal ETH/WETH sales are Seaport fills. The most recent is block 21853442 (token 268, WETH payments 28.3774 + 0.1426 = 28.52 ETH). Let me verify its receipt and timestamp in detail.Verified: Seaport OrderFulfilled — buyer 0x28d3bdec paid 28.3774 ETH to seller 0x5bcc60ff + 0.1426 ETH fee to OpenSea = **28.52 ETH total**, token 268, all WETH. Let me get exact timestamps and confirm no qualifying sale exists after it.Timeline is clear now: - **2025-02-15** (block 21853442): last literal WETH sale — token 268 via Seaport, 28.52 ETH total - **2025-08-10** (block 23110725): last sale of any kind — Blur, paid in Blur Pool tokens (6.58 ETH-equiv) — exc

I've read the brief. This is a panel-evidence NFT sale TWAP question on Ethereum mainnet. Let me check my tooling.block-at gives the last block at or before a timestamp, so block 26027905 is the first ≥ start (1790018145) and 26035049 the last < end (1790104545) — the pinned range matches the time window. Now let me pull the NFT's Transfer logs for the window and the 7-day seed lookback.Zero Transfer logs — either wrong event shape or a quiet contract. Let me see everything this address emitted in the window and probe what kind of contract it is.The contract exists — `name()` returns "Boo Bears", ERC721 — but emitted zero logs in the window and in the 7-day seed lookback. Let me find when it last transferred at all.No transfers in ~46 days back to block 25700000. Let me check the collection's total supply and scan further back for its last-ever transfer.totalSupply is 271 — a small Art Blocks–style collection with zero transfers in ~50 days. Let me verify it's genuinely dormant (any events at all recently) and cross-check with OpenSea/CoinGecko activity.CoinGecko confirms scope: Boo Bears, 271 supply, 6 unique owners, `volume_24h = 0` and `one_day_sales = 0`, floor 10.99 ETH. Onchain shows zero events of any kind for 100k+ blocks. Let me sanity-check the log tool against a historical range where the collection did trade, and find the last sale for the notes.The tool works — transfers exist in 25500000–25599999. Let me pull that range's logs and find the most recent one.Found the last transfer: block 25583186, token 152, tx `0x90d6...`. One gap remains unscanned: 25920000–25977499.Last-ever transfer was ~46 days ago; OpenSea API needs a key (unavailable — will note). Let me check whether that last transfer was a paid sale, for the notes.The window is definitively empty: zero events from the contract across the entire range, and the last-ever transfer was at block 25583186 (~46 days before start, outside the 7-day seed window) — and that tx has no marketplace settlement events anyway. Let me cross-check the pinned hash and the empty window on a second, independent endpoint as the reference requires.My hex conversion was wrong — let me fix it.Pinned hash and empty window confirmed on two independent endpoints (publicnode + mevblocker): toBlock hash matches, `fromBlock` ts 1790018147 ≥ start, `toBlock` ts 1790104535 < end. Zero transfers in-window on all three sources. The last-ever transfer (25583186) is outside the 7-day seed window and had no settlement events. Let me find the last verifiable *sale* for context — scanning transfers further back.Zero transfers from block 24000000 → 25583185 (~220 days). The collection is dormant. Let me try a public indexer (Reservoir) to locate the last actual sale, then verify it onchain.Reservoir is unreachable. Let me try large-range scans on the public endpoints for the full transfer history — faster than 100k chunks on the private node.mevblocker and tenderly serve large ranges. Let me pull the entire Transfer history of the contract.Full history fetched — 1897 transfers, most recent handful dating back to ~block 22254584+. Let me check which recent transfer txs contain marketplace settlement events.None of the recent transfers contain settlement events — they're wallet/app moves, not sales. To document the last verifiable sale properly, let me find the distinct transfer transactions and check them newest-first for marketplace settlement evidence.The April 2025 burst (~15 txs in blocks 22254932–22254968) could be a sale flurry. Let me check those transactions for settlement evidence.Rate-limited, but found what I needed: the most recent sale candidate is at block 21853442 (tx `0x678d63ab...`), ~Feb 2025 — everything newer is plain transfers. Let me decode that tx's settlement event to get the last verifiable sale price.That tx is a real Seaport 1.6 sale (two `OrderFulfilled` + `OrdersMatched`, WETH payments) at 2025-02-15 — ~7 months before the window. Let me decode it fully to see what w
