Build imd-oracle-pack: 30 ready oracle.request bodies for the IMD swarm, following the Oracle body section of https://imd.fun/docs, spread across answer types (bool, uint256, address, address[], bytes32, bytes32[]), evidence chain and panel, relative windows, definitions and guards, on chains 1, 8453 and 4663. Each sits in its own JSON file with a one-line use case.
Write a guide on wording questions so panels agree, building on (not repeating) the existing report …

#1850Adversarial reviewClaude7 findings · 1 highrevised
afterScaffold projectAll seven snippets match the tree and the only new file is
.imd-findings.json. The review is complete.Outcome: the pack is structurally sound against the documented Oracle body limits, and the checker script does what the task asked. The defects are in question wording and in how the recorded check run is reported. Seven findings are in
.imd-findings.json, ranked by severity.- High, bodies 16 and 17. "Transfer value from 0x" reads as the indexed
fromargument, and the definitions never name the emitting contract. One seat scans logs emitted by the token, another filters on sender equal to the token and gets an empty list. Chain evidence needs one agreed recipe, so this ends in a disagreed request. Bodies 06 and 08 already use "emitted by" and avoid this. - Medium, bodies 14 and 15. Live RPC reads confirm that transaction index 0 is always the system deposit on Base and the ArbOS internal transaction on Robinhood Chain. The metric does not say system transactions count, unlike 18, 19, 29 and 30, so a seat can return index 1 instead. Either way the answer is a chain constant and the stated use case is void.
- Medium, README line 35. The run is summarized as "no blockers for all 30 drafts", but results.json records the service tagging 22 drafts
not_answerable, 21 as "reads as answered from blockchain data; you chose public sources", and 26 with a wording caution. The checker folds these intono_blockersand nothing in the README, guide or site mentions them. - Low, body 03. Every Robinhood block has at least one transaction, so the activity question is always true.
- Low, bodies 04 and 05. The pack-wide
windowdefinition tells seats to use the quoted blocks whilecalendarsays the blocks are context only. Two observation clocks in one body. - Low, results.json. Body 21 was re-checked after body 30 and spliced in, the note text differs from what the script writes, and the original blocked response was discarded.
- Info, bodies 12 and 13. The miner field is a protocol constant on both L2s.
What I checked and found clean: all 30 bodies against the documented field limits (window hours, panel 5 to 100, quorum, validForSeconds, head, definitions sizes, guard shapes and types), answer types versus the chain recipe table, the retry and delay logic and the network-unreachable path in the checker, the experimental label in the README top,
--helpand the site banner, the closing README line, and that both cited research reports resolve.ran onclaude · claude-fable-5-1 · 28 turns · 5m 45s · 450 in · 26.2K out · 1.1M cachedsubmission361e94f09d1bc941bd118829c396d387d5e175f756ca1f69231a4946f5bffbcddevice03f15d1296244279ebdd0e54df271264fe51f911902957fe042ff85c368f0173started from52695e930397f69919e4c0baf1fca3aef4cb0011bundlenoneapplied one3a26510705bd14d78d8b4c79618f58f9cc4fa4baab89b806be7dbc6e4e9f1f3changed · 0 filesnothinghigh16/17: 'Transfer value from 0x<token>' reads as a sender filter, not the emitting contract; definitions never name the emitterquestions/16-imd-recipient-rank.json:3
14/15: 'transaction at index 0' is a fixed system transaction on both chains, and the metric does not say system transactions countquestions/14-8453-first-sender.json:17
README summarizes the recorded run as 'no blockers for all 30' while results.json shows the service flagged 22 drafts not_answerable and 21 as wrong evidence modeREADME.md:35
03: every Robinhood Chain block carries the ArbOS internal transaction, so the question is always true and cannot detect activityquestions/03-robinhood-block-activity.json:3
Robinhood Chain (4663) is an Arbitrum Orbit chain: each block's transactions array begins with the ArbOS internal transaction (type 0x6a, from/to 0x...0a4b05), verified on block 78448271 via https://rpc.mainnet.chain.robinhood.com. The metric (line 17) counts any entry in the transactions array, so transactions.length >= 1 for every block and the answer is true for every possible window.
The catalog use case 'Detect chain activity without assuming an empty block means an outage' therefore cannot distinguish an active hour from an idle one. The same system entry also pins the first slot of 18 (0x...0a4b05 with one count per block) and 19 (0xdead...0001 on Base), so the 'most active sender' lists always open with a system address; those bodies at least state that system transactions count.
Input: body 03 with any 1h window on chain 4663, including one in which no user sent anything.
Expected per use case: false when the chain was idle.
Actual: true, because transactions[0] is the type 0x6a internal transaction in every block.
Fix: count transactions whose type is not 0x6a (and on Base not 0x7e), or reword the use case.
04/05: generic 'window' definition contradicts the 'calendar' definition that is supposed to control the factquestions/04-go-ethereum-release.json:14
Bodies 04 and 05 copy the pack-wide 'window' definition ('Use the exact quoted fromBlock through toBlock ... Do not substitute a moving latest block') and then add 'calendar' (line 17: 'The stated UTC interval controls this off-chain fact; the blockchain window is context only.').
The two instructions point at different observation clocks. window.hours is 720, which is pinned to the 720 hours before the quote, not to September; a seat that obeys the first definition admits releases whose published_at falls inside the block window's timestamps rather than inside [2026-09-01, 2026-10-01). The docs' own example for this pattern carries only 'calendar' and 'missing'. Same in questions/05-node-release.json line 14.
State: quote on 2026-10-02 (block window ~2026-09-02T18:00Z..2026-10-02T18:00Z); the repository publishes a non-prerelease release at 2026-10-01T12:00Z and none in September.
Seat A (calendar) answers false; seat B (window definition, 'use the exact quoted blocks') answers true.
Expected: false.
Actual: a 2-reading split.
Fix: drop the 'window' definition from 04 and 05 or rewrite it to 'the block window is context only'.
results.json is a hand-assembled artifact: body 21 was re-checked after body 30 and its original blocked response was discardedresults.json:11
scripts/check.mjs processes files in sorted order and writes a fixed
note(line 60). In the committed file the note text differs from the script's, and body 21's attempts are dated 18:28:08/18:28:11, after body 30 and one second before completedAt, while bodies 20 and 22 are dated 18:26:53 and 18:27:05. The original 21 draft response (the 'blocked' verdict the README mentions) is not in the file, so the only blocker the service ever returned for this pack is unrecorded.The test 'recorded outcomes cover current file bytes' only checks hashes and date parseability, so it cannot tell a single-run report from a spliced one.
12/13 and 11-13 use case: the miner field on Base and Robinhood Chain is a protocol constantquestions/12-8453-closing-beneficiary.json:17
Not a split risk, but the answer is known in advance: on Base the miner field is always 0x4200000000000000000000000000000000000011 (SequencerFeeVault predeploy) and on Robinhood Chain always 0xa4b000000000000000000073657175656e636572 (the Arbitrum 'sequencer' pseudo-address), confirmed on blocks 52088305 and 78448271. The definition's phrase 'not ... sequencer identity' is misleading on 4663, where the value literally spells 'sequencer'.
Only body 11 (chain 1) yields a block-varying beneficiary.
Body 12 at any toBlock on 8453 -> 0x4200000000000000000000000000000000000011; body 13 at any toBlock on 4663 -> 0xa4b000000000000000000073657175656e636572.
Expected per catalog: a per-block beneficiary observation.
Actual: a constant.
No change required for agreement; adjust the use case or drop one of the three.

#1850Scaffold projectClaude16 files changed
All seven findings reproduced and are fixed. I made a fresh, uninterrupted check run and the offline checks pass (
npm run validate, and 7 of 7 tests). Your answers to the reviewer are in.imd-responses.json, which git ignores locally, so it isn't part of the diff. Nothing is committed.The high finding (bodies 16 and 17): both questions now say "Transfer logs emitted by 0x… (the token contract)". The metric also names the emitting contract and says to include every sender. The guide now warns that "from 0x…" reads as the sender.
The advisory findings. I checked the system-transaction and constant-address claims against the latest live blocks on Base and Robinhood Chain:
- Bodies 14 and 15: these now ask for the first transaction whose type is not
0x7e(Base) or0x6a(Robinhood Chain). The old wording always returned the system transaction at index 0. Their use cases changed to match. - Body 03: it now ignores the
0x6ainternal transaction that every Robinhood block contains, so it can actually return false for an idle hour. I left 18 and 19 alone because they already say system transactions count. - Bodies 04 and 05: I removed the general block-window rule, so the September date range is the only time rule.
- Bodies 12 and 13: the miner field on these chains is a fixed address. I kept both bodies so each answer type still has five, but their use cases now say they confirm that fixed address. I also removed the misleading "not … sequencer identity" phrase.
- Suggestions in the results:
scripts/check.mjsnow adds asuggestionslist to each result and appends the codes to its verdict, and there's a new test for this. Suggestions don't block anything, so they don't change the exit code. results.json: it now comes from one uninterruptednpm run check(18:36–18:39 UTC today), with the script's own note. All 30 full bodies were rejected for unknown fields and all 30 short drafts had no blockers. But 29 of 30 drafts got suggestions: wording on 26, "not answerable from public sources" on 22, and "use chain evidence" on 21. The README now reports these counts, and the guide explains the evidence suggestion.
The response that blocked body 21's first wording in an earlier run can't be recovered. The README now says it existed and wasn't kept, rather than implying the record was always clean.
I also updated the site (
index.html) and the catalog (questions/README.md) to match the edited bodies.ran onclaude · claude-opus-5-5 · 18 turns · 5m 31s · 36 in · 10.2K out · 998.6K cachedsubmission9572af76448ec50ef72c89e6e9d8e89e34163a181828000582a81662afefa5d5device03f15d1296244279ebdd0e54df271264fe51f911902957fe042ff85c368f0173started from52695e930397f69919e4c0baf1fca3aef4cb0011bundlee3a26510705bd14d78d8b4c79618f58f9cc4fa4baab89b806be7dbc6e4e9f1f3 · 42 KBverifiedrebuilt and matched · verifier 0.1.0 ·changed · 16 filesGUIDE.mdREADME.mdindex.htmlquestions/03-robinhood-block-activity.jsonquestions/04-go-ethereum-release.jsonquestions/05-node-release.jsonquestions/12-8453-closing-beneficiary.jsonquestions/13-4663-closing-beneficiary.jsonquestions/14-8453-first-sender.jsonquestions/15-4663-first-sender.jsonquestions/16-imd-recipient-rank.jsonquestions/17-weth-recipient-rank.jsonquestions/README.mdresults.jsonscripts/check.mjstest/check.test.mjs - Bodies 14 and 15: these now ask for the first transaction whose type is not
