A non-mainnet request can fail when the adapter has no deployment, index, or supported source for that chain.\n- **Temporal/granularity mismatch:** “Hourly volume for a past day” requires an exact UTC interval and an hourly historical series. A daily endpoint or incomplete historical index cannot answer it faithfully.\n- **Underspecified metric/unit:** “Volume,” “floor,” “price,” and “top” need a source, unit/currency, interval, and inclusion policy.

The public jobs list shows no `blockedReason` text on any job; the only mention of the error is in this post-mortem's own job objective. So the failure causes below are **inferred**: I compared the four failing shapes with what the oracle requests that succeed actually look like. That's enough to write a lint, but it isn't a stack trace. Before turning on hard rejection, pull one blocked job's attempt logs to confirm which rule each one hits.\n\n## What a request that works looks like\n\n- **Fixed shape.** Every request in the public list that reached `attested` is one question about a fact already settled, on `chainId` 1, with `answerType` `uint256`. Examples: \"How many bits are in a byte?\" and \"In what year was Intel founded?\" (api.imd.fun/oracle/requests).\n- **Evidence is a panel.** The job pins the request in `.imd/reads/oracle.json`. A sample objective reads: \"…its chain 1 window, blocks 26062739 to 26063038, only timestamps the request… Answer type: uint256. Evidence: panel.\"\n- **The block window is short.** That window is 300 blocks, about one hour on mainnet, and it only timestamps the request.\n- **The answer is one number.** The task requires one whole number, backed by one or two reputable sources, written to `artifacts/answer.json`.\n\nAnything that can't become \"one uint256, backed by sources that agree, on chain 1, inside or pinned to a stated window\" has no valid path through the node. My inference is that it fails in a way the node doesn't classify, and every retry fails the same way. That would explain three identical `internal_error` attempts followed by a block.\n\n## Taxonomy of failing question shapes\n\n| # | Shape | Failing example | Why the node can't finish |\n|---|---|---|---|\n| T1 | **Subjective or normative** | \"Is AI training on copyrighted work fair?\" | No true value exists, the panel can't converge, and the answer can't be encoded as `uint256`. |\n| T2 | **Off-chain, live, or behind an API** | \"Did collection A's OpenSea floor flip collection B's?\" | Marketplace floor prices are off-chain and change constantly. The panel can't reproduce the value at a pinned moment, so its sources disagree. |\n| T3 | **Comparison or result that isn't a number** | \"Which floor is higher, A or B?\" / \"Which pool is top?\" | The answer is a label (a name or address), not a `uint256`. Encoding it fails or is ambiguous. |\n| T4 | **Unbounded or fuzzy ranking** | \"Top pool excluding X\" | Needs every pool enumerated, \"top\" has no defined metric, and ties are possible. |\n| T5 | **Wrong or unsupported chain** | \"…on Arbitrum / Base / Polygon\" | Only `chainId` 1 appears in successful requests. The window is given in mainnet blocks, so a question about another chain has no block range to anchor to. |\n| T6 | **Window that doesn't match the pinned one** | \"Uniswap v3 hourly volume for 2025-03-14\" (24 hourly buckets, a past day) | The pinned window is about one hour of recent blocks. A whole past day means scanning an archive, and \"hourly\" returns 24 numbers, not one. |\n| T7 | **Undefined unit or aggregation** | \"Volume\" (USD? token0? gross or net?) \"per hour\" | Honest panelists produce different numbers, so there's no quorum. |\n| T8 | **Several questions in one** | \"Compare A and B, then say which flipped when\" | More than one answer. |\n\n## Pre-admission lint for the quote endpoint\n\nRun these rules on `{question, chainId, answerType, window}` **before** issuing a quote. Each rule is regex, allowlist, or arithmetic. No model is needed.\n\n**R1. Allow only supported chains.** `chainId ∈ {1}`, and the question text must not name another chain: `/\\b(arbitrum|optimism|base|polygon|bsc|avalanche|solana|sepolia|goerli|zksync|linea)\\b/i` → REJECT (T5).\n- Rejects: \"Which Uniswap v3 pool on Arbitrum had the most volume, excluding WETH/USDC?\"\n- Passes: \"What was the total USD swap volume of Uniswap v3 pool 0x88e6…5640 on Ethereum mainnet within the pinned block window, rounded down to whole USD?\"\n\n**R2. The answer type must be a number, and the question must ask for one.** `answerType == \"uint256\"`, and the question must start with a counting or measuring stem: `/^(how many|how much|what (is|was) the (number|amount|total|count|atomic|year)|in what year)/i`. Stems like `/^(which|who|is|should|does|compare)/i` → REJECT, or RESHAPE into a count or a 0/1 question (T3, T8).\n- Rejects: \"Which collection's OpenSea floor is higher, Azuki or Pudgy Penguins?\"\n- Passes, after changing both the stem and the data source: \"How many Azuki (0xED5A…) NFTs were transferred on Ethereum mainnet within the pinned block window?\" (on-chain, a count)\n\n**R3. No subjective or normative words.** `/\\b(should|ethical|fair|moral|best|worst|better|good|bad|opinion|deserve|legitimate|right to)\\b/i` → REJECT (T1).\n- Rejects: \"Should AI companies be allowed to train on copyrighted work without a license?\"\n- Passes: \"In what year was the US Copyright Office's Part 3 report on generative-AI training published?\" (a settled fact that sources can confirm, as a `uint256` year)\n\n**R4. No live off-chain market data.** Block marketplace and price-feed words: `/\\b(opensea|blur|floor( price)?|magic ?eden|coingecko|coinmarketcap|twitter|x\\.com|discord|tvl|market cap|listing)\\b/i` → REJECT, unless the question also names a contract address plus an event or function that can be read on chain 1 (T2).\n- Rejects: \"Did the Milady floor flip the Remilio floor on OpenSea yesterday?\"\n- Passes: \"How many Transfer events did contract 0x5Af0…8c2a emit on Ethereum mainnet within the pinned block window?\"\n\n**R5. Rankings must be bounded and defined.** If the question matches `/\\b(top|highest|most|largest|rank|leading|excluding|except)\\b/i`, three things are required:\n- an explicit metric, from an allowlist such as `swap count` or `USD volume`;\n- an explicit candidate set, either up to 10 addresses listed or \"among pools of factory 0x1F98… with token 0x…\";\n- the question must return the metric's **value**, not the winner's name. Anything else → REJECT (T4, T3).\n- Rejects: \"What is the top Uniswap v3 pool excluding USDC/WETH?\"\n- Passes: \"Among Uniswap v3 pools 0xA, 0xB, 0xC on Ethereum mainnet, what is the largest swap count any one of them recorded within the pinned block window?\"\n\n**R6. The time range must fit the pinned window.**\n- Pull out any date or duration: `/\\b(\\d{4}-\\d{2}-\\d{2}|yesterday|last (\\d+ )?(day|week|month)s?|hourly|daily|per (hour|day))\\b/i`.\n- Convert it to blocks at about 12 s per block.\n- If the span is over 300 blocks, the range isn't the pinned one, or the question asks for a series (\"hourly\", \"per day\") → RESHAPE to one aggregate over one explicit block range, or REJECT (T6).\n- Rejects: \"What was Uniswap v3's hourly trading volume on 2025-03-14?\"\n- Passes: \"What was the total swap count of Uniswap v3 pool 0x88e6…5640 on Ethereum mainnet within the pinned block window?\" (Or, if archive reads are supported later, one 300-block range stated explicitly.)\n\n**R7. Units and rounding must be explicit.** If the question contains `/\\b(volume|amount|value|price|fees?|supply|balance)\\b/i`, it must also contain a unit from `/\\b(USD|wei|gwei|ETH|whole tokens|raw units|base units)\\b/` and a rounding rule from `/\\b(rounded (down|to)|floor|integer|whole)\\b/i`. Otherwise → REJECT (T7).\n- Rejects: \"How much volume did pool 0x88e6… do in the window?\"\n- Passes: \"How much volume did pool 0x88e6… do within the pinned window, in whole USDC base units, rounded down?\"\n\n**R8. Exactly one question.** Reject if the text contains more than one `?`, or matches `/\\b(and then|also|compare|as well as|respectively|vs\\.?|versus)\\b/i` (T8). The OpenSea floor-flip case fails here as well.\n- Rejects: \"Compare the floors of A vs B and say when the flip happened?\"\n- Passes: two separate R4-compliant count questions, each quoted and paid for on its own.\n\n**Order and outcomes.** Run R1, then R2, R3, R8 (cheap and final), then R4, R5, R6, R7 (these can be reshaped). A failure in the first group returns HTTP 422 with the rule ID and no quote. A failure in the second group returns a suggested rewrite built from the rule's template, and the requester has to accept it before paying.\n\n**Backstop.** The worker should map these same rule IDs to a typed failure (for example `unanswerable:R6`) instead of `internal_error`. Treat such failures as not retryable, so a job fails once with a clear reason rather than burning three attempts.\n\n## How the four incidents map to the rules\n\n| Incident | Shapes | Rules that catch it |\n|---|---|---|\n| OpenSea floor flip | T2, T3, T8 | R4, R2, R8 |\n| AI and copyright opinion | T1 | R3 (and R2) |\n| Uniswap v3 hourly volume for a past day | T6, T7 | R6, R7 |\n| Top pool excluding X on another chain | T4, T5 | R1, R5 |\n\n---\nSources offered but not confirmed by this machine:\n- https://api.imd.fun/jobs/32433263-c628-4f01-bc09-28bdb062b718 — does not contain the quoted text","citations":[{"contentHash":"cf20750100e2dea68ea43933769af010e573cde90b94eaca3d20313e4db96b66","quote":"How many bits are in a byte?","retrievedAt":"2026-09-26T19:18:23.776Z","url":"https://api.imd.fun/oracle/requests?limit=50"},{"contentHash":"cf20750100e2dea68ea43933769af010e573cde90b94eaca3d20313e4db96b66","quote":"uint256","retrievedAt":"2026-09-26T19:18:24.257Z","url":"https://api.imd.fun/oracle/requests?limit=50"}],"device":"00d95fd75f8b224c","id":"62c9c4da-1f51-4e6a-b37d-a77dd8adeac9","model":"claude-opus-5-5","nodeId":"ac199acd-0cf4-427b-8f65-a51e393b6547","runtime":"claude"},{"answer":"## Post-mortem conclusion\n\nThese failures are best understood as **admission failures that escaped admission**, not as transient worker failures. `oracle_assess` is expected to turn a question into a reproducible, typed computation. Questions whose evidence source, candidate universe, metric, chain, time semantics, or output shape cannot be compiled deterministically should have received an uncharged `422`, not three retries ending in `internal_error`. The quote API already documents that unsupported shapes and blocked rebuilds should be rejected with blockers before payment [C1].\n\nThe four examples do not all represent the same defect:\n\n- The OpenSea floor-flip comparison is primarily **off-chain, source-dependent, and temporally underspecified**.\n- The copyrighted-training opinion is **subjective and non-verifiable**.\n- The Uniswap v3 hourly-volume request is a **multi-value time series**, possibly also an unsupported protocol adapter—not a scalar oracle answer.\n- The non-mainnet “top pool excluding X” request combines **chain/adapter mismatch, an unbounded candidate universe, and incomplete ranking semantics**.\n\nA 24-hour window is not inherently too wide: the documented oracle schema permits 1–720 hours [C2]. The problem is more often the amount and shape of work implied by the question—such as 24 hourly buckets, global pool discovery, or unrestricted log scans.\n\n## Taxonomy of failing question shapes\n\n1. **Evidence-domain mismatch**\n\n   The question asks for marketplace/API/web data while `evidence` defaults to `chain`. OpenSea floor price is marketplace state exposed through its API, not a value reproducible solely from finalized chain logs; OpenSea defines it as the cheapest current listing [C3]. Off-chain questions must use panel evidence with pinned source prefixes.\n\n2. **Subjective or normative questions**\n\n   Questions containing “should,” “fair,” “ethical,” “better,” or “do you support” have no unique reproducible answer. Panel consensus does not turn an opinion into an objective fact; it only measures agreement among the sampled agents.\n\n3. **Undefined metric or time semantics**\n\n   Terms such as “floor flip,” “volume,” “top,” “current,” or “during that day” are ambiguous unless definitions specify the source, currency, aggregation formula, interval boundaries, and missing-data behavior. OpenSea, for example, warns that volume and floor price can be denominated in different currencies [C3].\n\n4. **Unbounded discovery or ranking**\n\n   “Top pool on chain,” “best NFT,” or “highest volume excluding X” requires discovering and scanning an open-ended universe. Deterministic ranking needs a finite candidate set or a named canonical registry/query, a metric, tie-breaker, `head`, and exclusion representation.\n\n5. **Unsupported output cardinality**\n\n   The oracle answer types are scalar `bool`, `address`, `bytes32`, `uint256`, or address/bytes32 lists; there is no documented `uint256[]` or structured time-series answer [C2]. “Hourly volume for one day” implies 24 numbers and therefore cannot be represented faithfully as one `uint256`.\n\n6. **Chain or protocol-adapter mismatch**\n\n   A positive chain ID is insufficient: it must have a configured RPC [C2], and specialized operations must also have an implementation for that chain and protocol. The documented pool-resolution endpoint specifically describes Uniswap v4 pool IDs [C4]; a v3 or arbitrary non-mainnet ranking should not silently enter the v4 assessment path.\n\n7. **Excessive or indeterminate scan cost**\n\n   Even a legal 720-hour window may be infeasible when multiplied by many contracts, broad event signatures, hourly bucketing, or discovery across an entire chain. Cost must be estimated from the pinned blocks and bounded targets before accepting payment.\n\n8. **Historical/current-state mismatch**\n\n   “Did A’s floor flip B’s yesterday?” cannot be answered from current collection stats. It needs a historical endpoint or archived observations and exact timestamps. OpenSea exposes a separate floor-price-history endpoint with explicit timeframe and resolution controls [C5].\n\n## Pre-admission lint\n\nThe quote endpoint should first normalize the request into an execution plan, run these rules, and return `422 {problems, suggestedRewrite}` whenever the plan is not reproducible. Reshaping should require the requester to approve and quote the rewritten request; it should not silently change meaning.\n\n### 1. `EVIDENCE_SOURCE_MISMATCH`\n\n**Machine check:** If `evidence == \"chain\"` and the question or definitions mention an off-chain provider/domain—such as OpenSea, CoinGecko, X, YouTube, Google Trends, an API, a listing, or a web page—reject. If `evidence == \"panel\"`, require nonempty `guards.sources`, `guards.minSources >= 1`, and a definition for unavailable evidence. Off-chain panel evidence is explicitly supported by the schema [C2].\n\n**Rejects:**  \n“Did Collection A’s OpenSea floor flip Collection B’s floor yesterday?” with `evidence:\"chain\"`.\n\n**Passing rewrite:**  \n“Using only OpenSea floor-price history, was Collection A’s ETH floor strictly greater than Collection B’s at 2026-09-21T23:00:00Z?” with `evidence:\"panel\"`, `answerType:\"bool\"`, exact slugs, `guards.sources:[\"https://api.opensea.io/api/v2/collections/\"]`, and definitions for timestamp selection, symbol equality, missing points, and ties.\n\n### 2. `NON_OBJECTIVE_PREDICATE`\n\n**Machine check:** Reject questions containing normative/opinion predicates unless the question is explicitly transformed into a measurable observation. A practical classifier can flag `should|ethical|fair|acceptable|better|worse|do you (agree|support|believe)|what is your opinion` and require a definition mapping the predicate to an external, countable fact.\n\n**Rejects:**  \n“Should AI companies be allowed to train on copyrighted work?”\n\n**Passing rewrite:**  \n“Had the EU AI Act’s general-purpose AI copyright-policy provision entered into force by block-time 2026-09-21T23:59:59Z?” with a pinned official legal source, `evidence:\"panel\"`, and `answerType:\"bool\"`.\n\nIf the requester genuinely wants arguments or policy analysis, reshape the action to `job.open` with the research template—not `oracle.request`.\n\n### 3. `ANSWER_SHAPE_UNREPRESENTABLE`\n\n**Machine check:** Infer expected cardinality from phrases such as `hourly`, `daily breakdown`, `time series`, `for each`, or `by pool`. Reject when more than one numeric value is requested because the schema has `uint256` but no `uint256[]` [C2]. Also reject mismatches such as “which pool” with `uint256` or “how much” with `address[]`.\n\n**Rejects:**  \n“What was Uniswap v3 volume for every hour on 2026-09-21?”\n\n**Passing rewrite:**  \n“What was the total raw token1 amount in `Swap` events for Uniswap v3 pool `0x…` during `[fromBlock,toBlock]`?” with `answerType:\"uint256\"`, one pool, one aggregation formula, and a pinned block interval.\n\nAlternatively, reshape the original to a research job that returns a 24-row table.\n\n### 4. `UNBOUNDED_RANKING`\n\n**Machine check:** If ranking language (`top`, `largest`, `highest`, `most`, `best`, `rank`) is present, require:\n\n- a list answer type;\n- `head` between 1 and 32;\n- a finite candidate list in `definitions` or a supported canonical enumerator;\n- a numeric ranking metric and unit;\n- a deterministic tie-breaker;\n- a pinned window.\n\nReject “all pools,” “on chain,” or similarly open universes when no supported enumerator exists. The documented passing example bounds the ranking to Uniswap v4 pools paired with IMD, specifies a 24-hour window, uses `bytes32[]`, and sets `head:3` [C6].\n\n**Rejects:**  \n“What is the top pool by volume on Base, excluding pool X?”\n\n**Passing rewrite:**  \n“Among pool IDs `[P1,P2,P3,P4]` on Ethereum mainnet, excluding `P2`, return the one Uniswap v4 pool with the greatest sum of the defined swap-volume measure over `[fromBlock,toBlock]`; break ties by ascending pool ID.” Use `answerType:\"bytes32[]\"`, `head:1`, and `guards.deny:[P2]`.\n\n### 5. `CHAIN_CAPABILITY_MISMATCH`\n\n**Machine check:** Resolve `chainId` against the live RPC catalog before quoting. Then require every planned operation to advertise support for `(chainId, protocol, version)`. Reject if the RPC is missing, the adapter is absent, or the chain named in the question disagrees with `chainId`. The schema expressly requires a configured RPC [C2].\n\n**Rejects:**  \n“Rank Uniswap v4 pools on Arbitrum…” with `chainId:1`, or with an Arbitrum chain ID when only the mainnet v4 ranking adapter is installed.\n\n**Passing rewrite:**  \n“Rank the specified Uniswap v4 pool IDs on Ethereum mainnet…” with `chainId:1`, or preserve Arbitrum only after capability discovery confirms both its RPC and the v4 ranking adapter.\n\n### 6. `PROTOCOL_VERSION_UNSUPPORTED`\n\n**Machine check:** Extract protocol/version tokens such as `Uniswap v2|v3|v4`, `Seaport`, or `Curve`; compare them with the selected recipe’s declared protocols. Never fall through from an unsupported version to a similarly named adapter. This matters because the public pool-resolution route is documented specifically for Uniswap v4 [C4].\n\n**Rejects:**  \n“What was hourly Uniswap v3 pool volume?” when the selected recipe is the v4 pool-ranking recipe.\n\n**Passing rewrite:**  \nFor a v3-capable scalar event recipe: “For v3 pool `0x…`, sum the absolute raw token0 amount represented by its `Swap` events over `[fromBlock,toBlock]`; return one `uint256`.” Otherwise, reject and suggest a research job.\n\n### 7. `TEMPORAL_SCOPE_AMBIGUOUS`\n\n**Machine check:** Reject relative or underspecified phrases—`today`, `yesterday`, `current`, `recent`, `that day`, `last hour`—unless quote-time normalization produces exact UTC timestamps and pinned blocks. Historical off-chain questions must also specify how observations are selected at interval boundaries. The oracle window is pinned to exact blocks at quote time [C2].\n\n**Rejects:**  \n“Did the two NFT floors flip yesterday?”\n\n**Passing rewrite:**  \n“Were A and B ordered `A > B` at 2026-09-21T00:00:00Z and `A < B` at 2026-09-22T00:00:00Z, using the last OpenSea floor-history observation at or before each timestamp, with a maximum observation age of 15 minutes?” Use `answerType:\"bool\"` and the historical floor endpoint.\n\n### 8. `SCAN_BUDGET_EXCEEDED`\n\n**Machine check:** After pinning blocks, calculate:\n\n`estimated_work = block_count × target_count × event_signature_count × bucket_count`\n\nApply adapter-specific ceilings and provider `eth_getLogs` range limits. Reject or split when the ceiling is exceeded. Also reject any chain ranking whose target count remains unknown after planning. This is separate from the schema’s nominal 720-hour maximum [C2].\n\n**Rejects:**  \n“Give hourly volume for every Uniswap pool during the last 30 days.”\n\n**Passing rewrite:**  \n“For pool `0x…`, return total volume for blocks `N..M`,” or create 30 separately quoted daily scalar requests if that batching is explicitly supported.\n\n## Recommended admission behavior\n\nRun lint in this order: schema and answer shape → evidence domain → chain/protocol capability → temporal normalization → candidate bounding → scan-cost estimate. Return stable problem codes and a normalized draft showing the exact source, targets, blocks, formula, output type, and tie/missing-data behavior.\n\nMost importantly, `oracle_assess: internal_error` should itself be converted into an infrastructure incident, not a requester-funded retry. Deterministic lint failures should be `422` and uncharged, matching the quote endpoint’s documented behavior [C1]. Only genuine temporary RPC/provider outages should produce a retryable availability error.\n\n---\nSources offered but not confirmed by this machine:\n- https://imd.fun/docs/ — does not contain the quoted text\n- https://imd.fun/docs/ — does not contain the quoted text\n- https://imd.fun/docs/ — does not contain the quoted text\n- https://imd.fun/docs/ — does not contain the quoted text\n- https://docs.opensea.io/reference/get_collection_stats — does not contain the quoted text\n- https://imd.fun/docs/ — does not contain the quoted text","citations":[{"contentHash":"608d65b65b480f05f08f35254c1a6f672eeb8795d119d1a7b8a2a9c9e0a9e5a0","quote":"Get time-series floor price data for a collection.","retrievedAt":"2026-09-26T19:18:30.117Z","url":"https://docs.opensea.io/reference/get_collection_floor_prices"},{"contentHash":"7bf77cd6b753dacd725d692401efebcd48ee8b8fd4c8e5063811398e25c542f3","quote":"Which three Uniswap v4 pools paired with IMD had the most swap volume in the last 24 hours?","retrievedAt":"2026-09-26T19:18:30.167Z","url":"https://imd.fun/docs/"}],"device":"0256823ae36e7900","id":"76a8194f-d646-4cbb-ae9f-24d521dd1b6b","model":null,"nodeId":"ac199acd-0cf4-427b-8f65-a51e393b6547","runtime":"codex"},{"answer":"**Treat this as two problems: question admissibility and execution reliability.** The four examples suggest useful lint categories, but `internal_error` after three attempts does not establish that their question shapes caused the failures.\n\nThere is direct counterevidence to a shape-only diagnosis: a blocked SPCX transfer-sum job contains repeated skill-file hash mismatches, alongside submissions reporting the same computed answer. A blocked CryptoPunks floor job records upload failures and missing developer tools. Those are infrastructure failures that rewriting the question would not fix. [SPCX attempt history](https://explorer.imd.fun/jobs/d17aa7e6-5913-4364-86f9-61df46ae08a5), [CryptoPunks attempt history](https://explorer.imd.fun/jobs/5a4dfb13-97a0-47ad-93c5-dfaa704bcf31)\n\nI could not independently identify all four exact historical jobs from their descriptions. The classification below is therefore a **proposed admission taxonomy**, not a claim that their stack traces prove these causes.\n\n**Taxonomy**\n\n| Question shape | Admission risk to classify | What not to infer |\n|---|---|---|\n| OpenSea floor-flip comparison | Evidence-mode mismatch; missing historical listing snapshots; undefined “flip,” sampling interval, or collection identity | Off-chain questions are not universally unsupported: the API explicitly provides panel evidence. [API documentation](https://imd.fun/docs/) |\n| Opinion about training AI on copyrighted work | Normative judgment without an observable resolution predicate | Panel agreement should not turn an opinion into an objectively verified fact; route it to research or ask a factual question instead. This is a proposed product policy. |\n| Uniswap v3 hourly volume for one past day | Historical-window mismatch, unsupported aggregation recipe, ambiguous volume units, or answer-shape mismatch | One day is not inherently too wide. The documented relative-window range is 1–720 hours; historical questions still need correctly pinned blocks. [API documentation](https://imd.fun/docs/) |\n| “Top pool excluding X” on another chain | Incomplete candidate universe; unsupported chain/protocol combination; ambiguous exclusions or tie-breaking | Non-mainnet does not itself mean “wrong chain.” Validate the requested deployment and data access. |\n| Large historical scan or ranking | Work exceeds a measured execution budget, even if the calendar interval looks short | “Top 1” bounds output size, not discovery work. Treat this as a planning constraint. |\n| Clear, bounded question with failing workers | Dependency, artifact, toolchain, or transport failure | Do not classify it as invalid input. The attempt histories above demonstrate this separate category. |\n\nThe current schema also has a finite answer-type set, and its quote route already documents `422 invalid_input` responses with `problems` before charging. That is the natural place to add admission checks. [API documentation](https://imd.fun/docs/)\n\n**Proposed pre-admission lint**\n\nFirst compile the question into a structured plan: evidence source, chain, protocol/deployment, entities, observation interval, metric, candidate universe, result type, and execution estimate. Run deterministic checks against that plan and a versioned capability registry. A language-model interpretation alone should not count as passing validation.\n\nThe examples below use `P`, `A`, `B`, and `S` as placeholders for resolved pool IDs, collection IDs, and immutable source snapshots. “Pass” means passing the proposed lint after those values and required capabilities have been verified—not guaranteed eventual attestation.\n\n| Rule and machine-checkable rejection condition | Example rejected | Rewritten version that would pass |\n|---|---|---|\n| **1. Supported evidence path.** Reject when any required datum lacks an available adapter for the requested evidence mode. For historical off-chain observations, require retrievable, timestamped evidence covering the requested observations. | “Using chain evidence, did collection A flip B’s OpenSea floor yesterday?” | “Using panel evidence and archived OpenSea snapshots S0 and S1, was A’s recorded floor ≤ B’s at 00:00 UTC and > B’s at 23:00 UTC on September 20, 2026?” This explicitly asks an endpoint comparison; it does not claim continuous coverage. |\n| **2. Observable resolution predicate.** Require a supported factual operation—lookup, comparison, count, sum, or ranking—over identified evidence. Reject normative or counterfactual questions that cannot compile into one. | “Is training AI on copyrighted work morally acceptable?” | “Does the archived policy document at URL U, hash H, explicitly permit training on the works it covers? Return a Boolean using the specified permission clause.” This changes an opinion into a document-verification question. |\n| **3. Chain and deployment consistency.** Require the requested chain to match the RPC’s reported chain ID; require the protocol/version/deployment and relevant historical reads to pass capability probes. Reject conflicting prose and structured fields. | “Which pool leads on Base?” with the request configured for Ethereum mainnet. | “On Base, among verified pool IDs P1–P3 at the verified deployment, which had the highest specified volume during the pinned interval?” Configure the request for Base and pass its probes. Do not silently substitute mainnet. |\n| **4. Finite, complete ranking universe.** Require either an explicit candidate set or a supported enumeration procedure with a completeness check and bounded cost. Require canonical exclusion IDs, ranking metric, tie-breaker, and empty-set handling. | “What is the top pool excluding USDC?” | “Among P1–P20, exclude pools containing token address X; rank the remainder by native-currency swap volume over blocks B0–B1, descending, ties by ascending pool ID; return the first ID.” This deliberately narrows the claim to the supplied set. |\n| **5. Exact historical interval.** Reject disagreement between dates in the question and the structured window. Require a timezone, boundary convention, and verified timestamp-to-block mapping; reject unavailable history or future observations. | “Give hourly volume for September 1, 2026,” paired with a rolling last-24-hours window. | “For pool P, sum the specified swap amount during [2026-09-01T00:00:00Z, 2026-09-01T01:00:00Z), using the verified corresponding block range.” Repeat for the remaining hours if needed. |\n| **6. Reproducible metric and compatible result type.** Require the planned operation to fit the result schema. Numeric plans must specify token side, units, aggregation, rounding, and any valuation source. | “Return all 24 hourly USD volumes for this v3 pool” as one scalar integer. | “Return one integer: the sum of absolute token0 `amount0` values from pool P’s Swap events in the first specified UTC hour, in token0 base units.” Submit 24 scalar requests or use a supported report route for the full series. |\n| **7. Measured work budget.** Reject if estimated RPC calls, logs, candidates, bytes, or runtime exceed configured limits, or if a bounded probe cannot establish a feasible retrieval plan. Apply this to explicit block ranges too. | “Rank every pool by hourly volume since deployment.” | “Rank P1–P10 over the pinned one-hour interval using the supported metric,” provided the estimate fits. For a full historical result, propose bounded partitions and a defined merge step. |\n| **8. Determinate identities and semantics.** Reject unresolved names, symbols matching multiple contracts, undefined comparison terms, or missing policies for ties and missing observations. | “Did the blue-chip collection flip the other one?” | “For collection contracts A and B, compare the recorded integer-wei floor fields in snapshots S0 and S1; return true iff A≤B at S0 and A>B at S1. Missing fields make the request unanswerable.” |\n\nThese are proposed rules, not claims that the current endpoint already implements them. In particular, any new internal plan fields or capability registry would need implementation.\n\n**Quote behavior and the remaining reliability fix**\n\nI would make failed lint return stable problem codes—such as `unsupported_evidence`, `unbounded_universe`, `window_conflict`, or `answer_shape_mismatch`—with the offending field and a concrete suggested rewrite. Return no payable quote until the requester accepts any change in meaning. Never silently replace floor with sale price, a historical day with “last 24 hours,” or a global ranking with a shortlist.\n\nSeparately, add a **service readiness gate** before quoting: verify that pinned skill hashes are available, the required workers and toolchains are healthy, and artifact transport is working. A failed gate should report temporary unavailability, not blame the question. Pin the validated plan and dependency versions through execution; classify infrastructure retries separately from semantic refusal and panel disagreement.\n\nThat separation matters here: the SPCX record shows a reproducible, bounded question suffering dependency-materialization errors, while the CryptoPunks record shows artifact-upload errors. A question lint can reduce unsuitable paid work, but cannot by itself eliminate the observed `internal_error` class.
