• 1.mediumBuilder: 'latest frozen version within REVISION_DAYS' is read at build time, so the root depends on WHEN the window is built; late credit is missed and two operators get different rootspilot/build-tally.mjs:204

    for (let k = -1; k <= REVISION_DAYS; k++) {

  Commit 953d7c7 takes the LAST leaf found for the job in the receipts of day-1..day+REVISION_DAYS. receipt(d) (line 137) returns null when WorkRegistry.latest(dayJobId(d)) is zero, and the loop treats null exactly like 'the job was not revised that day'. A day not anchored YET is therefore indistinguishable from a day with nothing, and nothing in the builder requires the window's last answer day + REVISION_DAYS to be anchored: the only time rule is toBlock < head (line 63). So the result depends on the wall-clock time of the run.

  1. A build made soon after the window ends (the normal case) reads the ORIGINAL credit of every request answered in the last ~REVISION_DAYS; a revision anchored later (the split-panel late credit this commit exists for) is never paid, because the request is counted only in the window holding its Completed block and the window is consumed once posted (retire does not hand it back). A revision that removes an agent is the reverse: that agent was paid under a superseded version. No double payment across epochs.
  2. Determinism fails: a governor rebuilding one or two days later reads more receipts and gets a different root, so the 24 h veto cannot tell an honest early build from a wrong root, and the README's 'rebuildable by anyone' property does not hold.
  3. The refusal/success outcome is itself time dependent: a first frozen version with an empty oracleAcceptance refuses ('do not all answer this request'), and a superseded document can disappear from the records API, in which case frozenDoc throws an uncaught error (exit 1, not the documented exit 2). Live evidence (2026-10-29, Tenderly RPC): WorkRegistry.latest for 2026-10-26..28 is anchored and for 2026-10-29 is 0x00..00, so a build today of a window ending yesterday reads days 10-29..10-31 as empty. Job 569e4f4c-dc58-4e3f-9c9e-bc09837092a8 (oracle request d73223d0-54b9-4b91-a727-576597042689, attestedAt 2026-10-14T00:43Z, status attested) is listed in the 2026-10-13 receipt (0x7514...7b9a) with documentHash 9559ecc8...85fc, which api.imd.fun/work-records now answers 404 'unknown_record', and in the 2026-10-14 receipt (0xf35c...cff3) with documentHash 1c3fb8d5...9f96 naming agents 51553, 52713, 51046. A build between the Completed on 10-14 and the anchoring of the 10-14 receipt crashes on the 10-13 version (work record not found); a build afterwards pays three agents. Four specialists reported this (permissions, math, economics, flow); merged. Fix (builder only): before stage 3 refuse (exit 2) unless the receipt for addDays(day, REVISION_DAYS) is anchored for every credited request (or the run is past that day plus the plane's anchoring lag), treat a zero anchor for a past day as 'not proven yet'; write every receipt hash read, the head block and REVISION_DAYS into requests.json/tally.json; document in the README that an epoch's --to must be at least REVISION_DAYS + 1 days old.

  whole finding

  State: request U Completed(status 0) at block B inside the window, attested on day D; the receipt for D lists job J with document v1 crediting agents {A,B}; on D+2 the plane anchors a receipt listing J with document v2 crediting {A,B,C}.

  Run 1 on D+1: receipt(D+1..D+3) return null (latest()==0), found = v1, shares A=B=0.75e18, root R1, exit 0, posted as epoch N; nextFromBlock = toBlock+1.

  Run 2 on D+4 with the same --pilot/--to: found = v2, shares A=B=C=0.5e18, root R2 != R1.

  Expected: one root per window, C paid 0.5 imdUSD or the run refuses.

  Actual: R1 is posted, C is never paid (propose for blocks <= toBlock reverts WindowNotContiguous), and a governor rebuilding on D+2 or later sees the honest epoch as wrong.

  Live instance: cast call 0xb6d0a187b050fa5bb0b87033a203f37becf4a775 'latest(bytes16)(bytes32)' with dayJobId('2026-10-13') and dayJobId('2026-10-14') both list jobId 569e4f4c-dc58-4e3f-9c9e-bc09837092a8 with different documentHash values; the first document is 404 at the records API, the second credits 3 agents.

• 2.lowBuilder: REVISION_DAYS and LOOKBACK change the root or the refuse/success outcome but are not written to tally.json, so a published tally is not reproducible from its own inputspilot/build-tally.mjs:31

  const REVISION_DAYS = Number(process.env.REVISION_DAYS ?? 3);

  The root is a function of the window, the chain, the frozen documents AND two environment inputs: REVISION_DAYS (which frozen version of a job is eligible, line 204) and LOOKBACK (whether a Requested event is found at all; a miss is a refusal, line 168). The summary written at lines 260-267 records bonusPerRequest and the script path as the reproducibility inputs but neither of these.

  A governor rebuilding with the defaults during the veto window gets a different result from a poster who exported REVISION_DAYS=0 or 7, and tally.json gives no hint why. Reported by the permissions specialist (with a live dry run: REVISION_DAYS=3 on 26194146..26215746 builds root 0xebaa5549...d824 while REVISION_DAYS=0 refuses two requests). Distinct from the time-dependence finding: its fix is to pin or record the inputs.

  Fix: make both explicit flags or constants and write them (plus the head block and every receipt hash read) into tally.json next to bonusPerRequest.

  whole finding

  cd pilot; REVISION_DAYS=3 node build-tally.mjs --epoch 0 --from 26194146 --to 26215746 --out a -> a root; REVISION_DAYS=0 node build-tally.mjs --epoch 0 --from 26194146 --to 26215746 --out b -> exit 2 (jobs anchored a day after their attestedAt are 'not in the receipts'). a/tally.json has no field naming the value that produced it (summary keys: dryRun, pilot, epoch, fromBlock, toBlock, root, total, scaledToCap, bonusPerRequest, paidRequests, agents, skipped, script). Expected: every input that affects the root is recorded.

• 3.lowBuilder: a paid request that can never be proven blocks every later epoch permanently; contiguity makes 'end the window earlier' a one-time remedy and there is no recorded overridepilot/build-tally.mjs:233

    console.error("Nothing written. Post when those receipts are on chain, or end the window earlier.");

  Round-one fix 7 rightly turned every uncertain case into a refusal (exit 2), but several refusal causes do not resolve by waiting: (a) a status-0 Completed whose uri does not match //oracle/requests/([0-9a-f-]{36})/ (another uri form, or an upper-case UUID, line 163/172); (b) GET /oracle/requests/ answering 404 for good (verified: an unknown id answers 404), or a final status other than 'attested' for a request the Intake completed with status 0 (round one saw 'disagreed' on such ids), lines 197-198; (c) a job absent from every receipt in day-1..day+REVISION_DAYS (a day the plane never anchored, or attestedAt missing so createdAt is used and the job is anchored later than +3), line 210; (d) a frozen document whose acceptance entries do not all name the request, line 215; (e) a receipt leaf whose document the records API no longer serves, where frozenDoc throws (uncaught, exit 1).

  The contract requires fromBlock == nextFromBlock (src/PaidOraclePilot.sol:220) and toBlock >= fromBlock, so a window cannot route around block B: 'end the window earlier' works once (--to B-1), after which nextFromBlock == B and every later run includes B and refuses again.

  The pilot's remaining lifetime budget is then stuck with no on-chain defect; the only ways out are editing the published script (breaking the 'built by a published script from public inputs' statement in the NatSpec), setPoster(0), or a hand-built root. README line 53 ('Wait, or end the window earlier; nothing is lost') is wrong for these cases. Four specialists reported it; merged.

  The frozen data already carries the mapping (every acceptance entry has document.oracle.attestation.requestId), so a live-API 404 need not be fatal.

  Fix: classify refusals as transient or permanent; fall back to scanning the receipts around the Completed block's day for a document whose entries all name U; add an explicit, recorded exclusion input (e.g. --exclude :) written into tally.json's skipped so the governor sees it in the veto window; lower-case the uri before matching; correct the README sentence.

  Expected: a documented way to exclude R visibly or prove U from frozen receipts.

  Actual: no epoch can be posted again; epochCount() stays constant while paid work after B accumulates uncounted.

• 4.lowBuilder lets a window end one block below an unfinalized head; a reorg after the log read can pay a Completed event twice across two epochs or never, and contiguity makes it uncorrectablepilot/build-tally.mjs:63

  if (toBlock >= head) throw new Error(`--to ${toBlock} must be before the current block ${head}`);

  Question 5 answered: an honest poster can always post (block.number only grows, so any toBlock < head at build time satisfies toBlock < block.number at inclusion; verified propose accepts block.number - 1 and refuses block.number). The defect is the other direction: head is getBlockNumber() ('latest'), logs are read at 'latest', and nothing requires toBlock to be finalized.

  The two-provider agreement check catches a lagging provider, not a reorg that happens after both answered. Mainnet still sees occasional 1-2 block reorgs. If a Completed event in block toBlock is reorged out and re-included at toBlock+1 or later, epoch N (built before the reorg) pays it and epoch N+1 (window starting at toBlock+1, seen is per run) pays it again; if an event is reorged INTO the window after the read, neither epoch pays it.

  The posted root is accepted regardless and the window cannot be recounted after 24 h. Anchoring lag of the daily receipts makes this rare but does not prevent it (a request answered just before midnight UTC whose receipt is anchored quickly). Four specialists reported it; merged.

  Fix: bound --to by the finalized block (client.getBlock({ blockTag: 'finalized' }) from both providers) and record toBlock's block hash in tally.json so a rebuild detects a reorg; optionally require toBlock + FINALITY_DEPTH < block.number in propose().

  whole finding

  Head H.

  Completed(R, 0, .., '/oracle/requests/U') is in block H-1 in both providers' view. node build-tally.mjs --pilot P --to H-1: accepted (H-1 < H); U credited in epoch N; the poster posts at block > H (accepted, H-1 < block.number).

  Block H-1 is reorged and the Intake completion lands in block H+1.

  Next build: nextFromBlock = H, window H..H+k contains Completed(R) at H+1, seen is empty, U credited again.

  Expected: each Completed counted once.

  Actual: U's agents receive 1.5 imdUSD twice (or, if the event moved into the window after the read, never).

• 5.lowBuilder --pilot mode reads epochCount() and nextFromBlock() from ONE provider with no cross-check; a stale read across a propose+veto pair yields a root for the wrong epoch number that propose() acceppilot/build-tally.mjs:50

    epoch = await client.readContract({ address: args.pilot, abi: pilotAbi, functionName: "epochCount" });

  Round-one fix 2/3 moved --epoch/--from from operator typing to chain reads, but the reads go to clients[0] only (mevblocker by default), with no block tag and no agreement check against clients[1], while every log read must agree between both providers precisely because a public RPC can answer wrongly without erroring. A wrong nextFromBlock is harmless (WindowNotContiguous).

  A wrong epochCount is not: the epoch number is hashed into every leaf, propose() cannot check it, and a stale provider CAN return a wrong epochCount with a correct nextFromBlock: epoch N (X..Y) is posted and vetoed on chain (nextFromBlock back to X, epochCount N+1) while the provider still serves the pre-propose state (epochCount N, nextFromBlock X).

  The build produces leaves (N, agent, amount) with fromBlock X; propose(root, total, X, Y') is accepted as epoch N+1; every pay() reverts BadProof; the governor can only retire it after 30 days and the window X..Y' is lost for good (see the retire finding). This is round one's 'mistyped --epoch' failure with the typo moved into the RPC. Reported by the permissions and flow specialists; merged.

  Fix: read epochCount, nextFromBlock and head from every client at the same block number and require agreement; warn when the latest epoch is still inside its veto window; optionally give propose() an expectedEpoch argument compared with _epochs.length.

  whole finding

  Chain: epoch 3 (1000..1500) posted at T, vetoed at T+1h: epochCount()==4, nextFromBlock()==1000.

  Build: leaves (3, agent, amount), fromBlock 1000, toBlock 1600, root R. propose(R, total, 1000, 1600, uri) succeeds as epoch 4 (fromBlock matches).

  After 24 h pay(4, ids, amounts, proofs) -> BadProof for every leaf; veto window closed; retire(4) only after 30 days; blocks 1000..1600 can never be recounted.

  Expected: the build refuses when the two providers disagree, as it does for logs.

• 6.lowretire() never hands the window back, even when paid == 0 and the epoch is the latest, so the paid work in a mistaken epoch's window is lost although a safe recount was possiblesrc/PaidOraclePilot.sol:194

      /// bind a seat). Its window stays counted: a correct recount of it is not possible after this.

  Question 3: keeping the window counted is right once any share was paid (a recount would double pay) or once a later epoch exists (contiguity). It is not right in the case retire() was written for: a mistaken root (wrong epoch number in the leaves, a typo) for which every pay() reverted BadProof, paid == 0, no later epoch.

  There the window could be handed back exactly as veto() does (nextFromBlock = e.fromBlock) with no double-payment risk, and the bonus for every paid request completed in it preserved. As written, the operator's only recovery for a wrong root that the Safe missed in its 24 h window is to lose that window's work for good. Round-one finding 2 asked for both the cap release and the floor fallback; the fix did the first only.

  Everything else about retire() is sound: released = total - paid never underflows (paid <= total by OverEpochTotal), veto and retire are mutually exclusive in time and each checks the other's flag, totalPaid <= totalCommitted <= LIFETIME_CAP holds through any order of pay/retire/propose (checked in test/scratch/Round2Judge.t.sol::test_retireStrandsOutstandingBatch_capsHold), and an epoch being paid in batches around day 30 cannot release more than its unpaid remainder.

  Reported by the math specialist.

  Fix: in retire(), if (e.paid == 0 && epoch == _epochs.length - 1) nextFromBlock = e.fromBlock; and document that a retired epoch with payments stays counted.

• 7.inforetire() is a governor power over any 30-day-old epoch, including one still being paid in batches: unpaid valid shares are stranded; NatSpec and README describe it only as 'for an epoch that cannot besrc/PaidOraclePilot.sol:200

          e.retired = true;

  The only gates are the vetoed/retired flags and the 30-day delay. An epoch whose shares are valid and whose batches are being submitted around day 30 (feeds stale for weeks, Unpayable agents who bind late, batches nobody submitted yet) can be retired between batch 1 and batch 2; batch 2 then reverts EpochRetired and those agents lose their shares for good, while the released cap can be re-posted to other recipients.

  Accounting stays sound (released == total - paid; totalPaid <= totalCommitted <= LIFETIME_CAP in every sequence). It cannot pay anything, cannot be used before day 30, and is consistent with the governor's veto power, so this is a trust assumption to record rather than a bypass: it is not in 'Who holds what power' (NatSpec or README), which say retire is for epochs that cannot be paid. Three specialists reported it; merged.

  Suggested: state the power, and either an operational rule (retire only after a final pay() attempt in the same bundle) or a contract guard such as requiring no Paid event in the last VETO_WINDOW (a lastPaidAt per epoch).

• 8.infoRegression test for round-one finding 4 does not exercise the finding's variant (the round-one contract accepts its whole sequence), and RESOLUTION's 'fails on old code with Panic 0x11' claim is not wtest/fork/PaidOraclePilot.t.sol:287

          pilot.propose(t.root, 3e18, 101, 200, ""); // epoch 2, narrower recount

  Question 1. Every contract fix closes its finding including the variants (verified by reading and by test/scratch/Round2Judge.t.sol: any toBlock >= block.number refused, any gap refused, a recount with a LATER start refused with WindowNotContiguous(101), bit 200 in the address word and 256 in the standard word skip one share). But two regression claims do not hold.

  (a) Finding 4 was: vetoed [201,300] recounted as [250,300] (later START), vetoed again, floor stuck at 250. test_consecutiveVetoesLoseNoBlocks narrows the END instead ([101,300] -> [101,200]); under the old rule floor = last.fromBlock = 101 and the final propose(101,300) was accepted by the round-one code too.

  Compiled 5f40fa0's contract as OldPaidOraclePilot and replayed: test_oldCode_acceptsTheFinding4RegressionSequence passes (epoch 3 created on the old code); the finding's sequence with epoch 2 = [250,300] reverts WindowNotAfterPrevious on the old code and WindowNotContiguous(101) on the new (test_finding4Variant_oldFails_newRefusesNarrowedStart).

  (b) RESOLUTION.md line 5 says test_windowCannotEndInTheFuture 'fails on old code with Panic 0x11'; on the old code propose(.., 1, type(uint64).max) is ACCEPTED, so the first expectRevert fails with 'call did not revert as expected', and the Panic appears only on the NEXT propose (test_oldCode_acceptsMaxToBlock_panicOnlyOnNextPropose).

  The test file itself does not compile against 5f40fa0 (three-argument constructor, nextFromBlock, retire, new errors), so neither claim can have been checked with the file in the tree. (c) Builder fixes 6, 7 and 10 are marked 'manual' with no fixture test, so the skip/refuse classification can regress unnoticed; and every pilot test lives in test/fork, so forge test offline exercises none of the pilot (a mock vault/adapter pattern, as in the scratch test, works offline).

  Four specialists reported parts of this; merged.

  Fix: make epoch 2 in the test start at 250 and expect WindowNotContiguous(101); extend test_windowCannotEndInTheFuture with 'a later propose still succeeds'; correct RESOLUTION; add an offline unit test and a fixture-driven test for the builder's classification.

  New in 548b006: nextFromBlock is seeded from a constructor argument with no check. propose() needs toBlock >= fromBlock == nextFromBlock and toBlock < block.number, so firstFromBlock above the head only waits for the chain, but firstFromBlock = type(uint64).max makes every propose revert (InvalidRoot when toBlock < fromBlock, WindowInFuture when toBlock == max) and there is no governor setter for nextFromBlock.

      if (!actionOf(r.args.action).startsWith("oracle.request@")) continue; // not an oracle request: out of the pilot

  pilot/README.md lines 47-49 say every definite exclusion is 'listed in skipped' and name 'not an oracle request' first. The code continues before skip(), so a Completed whose Requested action is not oracle.request@ appears neither in the stage-1 count nor in tally.json's skipped list.

  A reviewer comparing the Intake's Completed count with the tally's candidate + skipped counts (as round one did: 117 Completed vs 103 oracle requests) cannot account for the difference from the published files. Also note the order: a non-oracle Completed whose Requested is older than LOOKBACK refuses the run (line 168 runs before line 169), which is a false refusal the operator can only clear by raising LOOKBACK. Three specialists reported it; merged.

  Fix: skip('not an oracle request') instead of continue, and apply the action filter before the lookback refusal.

  Window with Completed(R, 0, ..) whose Requested action is 'premium.job@premium-1' paid in IMD.

  The round-one fix for finding 10 deduplicates by oracleId with a Set that lives for one run, so it covers only Completed events inside one window (across both INTAKES).

  The builder never reads earlier epochs' requests.json and the contract has no oracle-request key, so if the plane ever answers two Intake requests with one oracle request and the two Completed events land in different windows, each epoch pays the full 1.5 imdUSD for the same frozen document (the attestation check compares the ORACLE id, not the Intake id, so both pass). Plane-written-data robustness note; every oracle id in the dry-run window is distinct.

  Three specialists reported it; merged.

  Fix: seed seen from the oracleIds of every earlier non-vetoed epoch's published requests.json (via their EpochProposed uris), or document that dedupe is per window.

  Epoch 0: shares 0.75e18 each; epoch 1: seen is empty, shares 0.75e18 each again.

  Expected (README 'once per oracle request'): R2 skipped as a duplicate.

   The real problems are in the tally builder; I found nothing wrong in the contract. .imd-findings.json has five findings (1 medium, 2 low, 2 info), each with a concrete reproduction, and every snippet matches the tree. None is high or critical, so none carries a Foundry proof. No repository files were changed: I deleted my scratch test after running it.

   Checks run:

   • Fork suite: forge test --match-path test/fork/PaidOraclePilot.t.sol against live mainnet (publicnode RPC) passed 15 of 15.
   • My sequence test: an offline test of veto, narrower recount, veto again, a retire in between, then another veto passed. nextFromBlock and totalCommitted came out right at every step.
   • Not run: the full offline suite.
   • Builder: reviewed by reading the code only; I did not run it against the live API.

   Findings

   • [medium] Late revisions depend on when the builder runs (pilot/build-tally.mjs:204). A day whose receipt isn't anchored yet looks the same as "not revised that day".
     • An epoch built soon after its window ends uses the original credit. A split panel credited later is never paid, because the request isn't counted again in the next window.
     • A run a few days later gives a different root for the same window, so the governor can't check a posted root by rebuilding it.
     • Agents are not paid twice, but they can be paid under an old version or missed.
     • Fix: the builder refuses until every receipt day up to day + REVISION_DAYS is anchored, and records which receipt hashes it read. So yes, an epoch should wait REVISION_DAYS before it is built.
   • [low] One unprovable request blocks the pilot for good (:172, also 197, 210, 215). Example: a status-0 paid request whose uri uses an upper-case UUID or another format, or an API 404.

   Your questions

   1. Each contract fix closes its finding, including the round-one variants. The regression tests can't show that on the old code, as above.
   2. Contiguity holds in every sequence, including retire in between (my sequence test covers it). The "only the latest epoch can be vetoed" assumption is airtight. The 6-day gap is measured from the last epoch posted, vetoed ones included, and that is longer than the 24 h veto window.
   3. retire can't release more than was committed. totalPaid stays at or below totalCommitted, which stays at or below LIFETIME_CAP, so the lifetime cap holds for total minted. Retiring an epoch mid-payout just makes later batches revert. That is a governor power to document, not a bug.
      • Keeping a retired epoch's window counted is right: after 30 days, later epochs have moved past it and a recount would pay some shares twice.
      • The catch: an epoch with a wrong root loses its window's work unless it is vetoed within 24 h.
   4. No adapter answer still reverts the batch, and no well-formed ERC-721 binding is wrongly rejected.
   5. An honest poster can always post. The real issue is finality (third finding).
   6. Every uncertain case is now a refusal, but some refusals can be perma

   • mediumLate-revision lookup reads receipts that may not be anchored yet: the root depends on when the builder runs, so late credit is missed and two operators building the same window get different rootspilot/build-tally.mjs:204

     953d7c7 takes a job's LATEST frozen version among the receipts for day-1..day+REVISION_DAYS. But receipt(d) (line 137) returns null when WorkRegistry.latest(jobId(d)) is still zero, i.e. the day has not been anchored yet, and the loop treats that exactly like 'job not revised that day'. Nothing refuses or waits until day+REVISION_DAYS has been anchored, and the only time rule is toBlock < head (line 63).

     So the result depends on the wall-clock time of the run: an epoch built soon after its window ends (the normal case, and the only one the contract encourages, since the window may end one block before the head) reads the ORIGINAL credit for every request answered in the last ~REVISION_DAYS of the window.

     A revision anchored later (split panels credited late, plane PR #630, which is the case this commit exists for) is never paid: its request was counted once, in this epoch, and the next window starts after toBlock. A revision that removes an agent is the reverse: that agent is paid under a superseded version. Payment is not doubled, because each request is counted only in the window holding its Completed block, but it is paid under whichever version existed at build time.

     Determinism fails too. The governor checks a posted root by rebuilding it, and a rebuild a day or two later reads more receipts and gets a different root, so the 24 h veto cannot tell a wrong root from an honest one built earlier. Two more inputs are also read live: latest() is read at the current block (a re-recorded day would change it again), and the day comes from the mutable API's attestedAt.

     Request U: Completed status 0 at block B (window [from, to], B <= to), answered on 2026-10-20; job J appears in the 2026-10-20 receipt crediting agents {1,2} (half-panel) and again in the 2026-10-21 receipt crediting {1,2,3,4} (late split-panel credit), anchored on 2026-10-22.

     Operator A runs node build-tally.mjs --pilot P --to <to> on 2026-10-21 after the 10-20 receipt is anchored: receipt('2026-10-21'..'2026-10-23') return null, found = 2026-10-20 version, agents 1,2 get 0.75e18 each, and the run succeeds with exit 0.

     Operator B runs the same command on 2026-10-24: found = 2026-10-21 version, agents 1..4 get 0.375e18 each, so the root differs.

     If A's root is posted, agents 3,4 are never paid for U, because the next window starts at to+1 and U is not counted again.

     Expected: both runs give the same root, the late credit is the one used, or the run refuses.

     Fix (builder only): for each credited request, refuse (exit 2, like a missing receipt) unless every receipt day in [day-1, day+REVISION_DAYS] is anchored (latest != 0) or provably empty, or simply refuse while now < last request's day + REVISION_DAYS + 1.

     Write the receipt hashes read, plus the block they were read at, into requests.json so a verifier rebuilds from the same inputs.

   • lowA paid request that can never be proven blocks the pilot permanently: windows are contiguous, so every later build includes the same block and refusespilot/build-tally.mjs:172

     The round-one fix turned the uncertain skips into refusals (exit 2), which is right while the cause is temporary (receipt not anchored yet).

     Several refusals have causes fixed in chain events or in data the plane will not rewrite: (a) a status-0 IMD-paid oracle.request whose Completed uri does not match //oracle/requests/([0-9a-f-]{36})/ (another uri form, or an upper-case UUID), line 172; (b) the API answering 404 or a final status other than 'attested' for a request that was answered on chain (line 197-198; round one saw 'disagreed' on such ids); (c) a job missing from all receipts day-1..day+REVISION_DAYS, for example a day the plane never anchored or an attestedAt outside that range (line 210); (d) a frozen document whose acceptance entries do not all name the request (line 215); and frozenDoc throwing when a work record is 404 (line 119).

     The contract requires fromBlock == nextFromBlock (src/PaidOraclePilot.sol:220). The README's remedy, 'end the window earlier', works once: the next window must start at to+1 <= B and eventually contain B. So from block B on, no epoch can be built with the published script, and every later agent's bonus stops.

     The remaining choices are editing the script (the root is then no longer rebuildable from the published script), setPoster(0), or the governor posting a root by hand. None of these is documented.

     Every run --pilot P --to T with T >= B exits 2 with 'answered, but the uri names no oracle request'.

   • lowBuilder lets a window end one block behind an unfinalized head: a reorg can move a Completed event across the window boundary and pay the same request in two epochs (or pay one that was dropped)pilot/build-tally.mjs:63

     Question 5. An honest poster can always post: the builder needs toBlock < head at build time, and block.number at execution is always later. The contract check toBlock >= block.number (src/PaidOraclePilot.sol:219) refuses only future windows, so it never blocks an honest poster.

     But head comes from getBlockNumber(), the 'latest' unfinalized tag, and nothing requires toBlock to be finalized. Logs from blocks near toBlock can be reorged away after the run. The two-provider agreement check does not help, because both providers see the same pre-reorg branch.

     Deduplication (seen, line 189) is per run, so the next epoch does not know the request was already counted. In practice the anchoring delay of the day receipts makes this rarer, since a request answered within the last minutes usually refuses for 'receipt missing'. It is not prevented, though: a window whose last blocks hold a Completed for a job already in an anchored receipt (answered just before midnight UTC, receipt anchored quickly) is exposed.

     If the tx is dropped instead, epoch n pays for a request that was never completed on the canonical chain.

     The round-one fix for finding 10 deduplicates by oracleId with a Set that lives for one run, so it covers only Completed events inside one window. The finding's concern (one bonus per oracle request, however many Intake requests name it) is not closed across epochs: the builder never reads earlier epochs' requests.json, and the contract has no oracle-request key. The same applies across the two INTAKES (old and v2): they are deduplicated within a run only.

     Completed(R1, status 0, .., 'https://api.imd.fun/oracle/requests/U') in epoch 0's window and Completed(R2, status 0, .., 'https://api.imd.fun/oracle/requests/U') in epoch 1's window, both IMD-paid oracle.request@ and both attested by the same job.

     Epoch 0 credits U's agents 1.5e18 / n each, and epoch 1 credits them again: 3 imdUSD for one oracle request.

     Expected: the second is skipped as a duplicate.

     Question 1. The test references PaidOraclePilot.WindowInFuture and pilot.nextFromBlock() (test/fork/PaidOraclePilot.t.sol:252, 258), and neither exists at 5f40fa0 (git show 5f40fa0:src/PaidOraclePilot.sol | grep -c 'nextFromBlock\|WindowInFuture' gives 0). On the round-one code the file does not compile.

     Even with the names adapted, the old code ACCEPTS propose(.., 1, type(uint64).max), so the failure would be 'next call did not revert as expected', not Panic 0x11. The test never makes a second propose after a max toBlock, which is where the old Panic happened. The same holds for test_windowsAreContiguous, test_consecutiveVetoesLoseNoBlocks and the retire tests (no retire, no WindowNotContiguous at 5f40fa0).

     Only test_malformedBindingSkipsOneShareNotTheBatch compiles against the old ABI, and there controllerOf(OTHER) reverts in abi.decode, which is the right reason. I checked each contract fix by reading the code: each closes its finding, including the variants (any toBlock >= block.number, gaps of any size, a narrowed recount vetoed twice, the address word with bit 200 set).

     The builder fixes are marked 'manual' and have no test, so the refusal/skip classification can regress unnoticed.

Fix: state in RESOLUTION which tests were adapted to the old ABI and what each one actually reports there, extend test_windowCannotEndInTheFuture with the old failure sequence (attempt the far-future propose, then a later propose must still succeed), and add a fixture-driven test for the builder's stage-1/stage-2 classification (status 1/2 skip, lookback miss refuse, non-oracle uri refuse, duplicate skip, mismatched entry refuse).

   The review is complete. The findings file .imd-findings.json holds eight substantiated findings (3 low, 5 info), every snippet verified against the tree. No critical or high finding exists, so no proof file is attached. Scratch tests live under test/scratch/ only.

   Verification run

   Check	Result
   Fork suite, live mainnet via the task's public endpoint	15 passed
   Offline suite (excluding fork and scratch)	664 passed, 4 skipped
   Scratch suite (old contract vs new, decode edge cases)	6 passed

   Answers to the eight questions

   1. Fixes close their findings. All ten are closed, including the variants. Two regression notes: the finding-4 test narrows only toBlock, and the round-one contract accepts its whole sequence, so it does not fail on the old code for the finding's reason (info, with a scratch test proving both sides). RESOLUTION.md's claim that the toBlock test "fails with Panic 0x11" is inaccurate: it fails because the first propose does not revert.
   2. Contiguity and veto reset are airtight. A later propose needs 6 days after the last posting, a veto needs under 24 hours, so only the latest epoch is ever vetoable, including recount, veto again, and retire in between. One design consequence: a vetoed epoch still costs a 6-day slot before the recount, which is the intended rate limit.
   3. retire() is sound on accounting. It releases exactly the unpaid remainder once, total minted never exceeds the lifetime cap, and keeping the window counted is correct because paid shares cannot be separated in a recount. It has no guard for a still-payable epoch, so a batch waiting on feeds at day 30 can be stranded by the governor (info, trust assumption).
   4. controllerOf: clear no. Over-long, odd-length, dynamic-encoded, and short answers all skip the share without reverting; well-formed ERC-721 bindings resolve. Backed by a scratch test.
   5. toBlock < block.number: no honest poster is blocked, but it is not finality. A reorg at the window edge after the build double-counts or drops a Completed event, and contiguity makes it uncorrectable (low).
   6. Builder refusals can be permanent. A status-0 completion whose oracle id the plane 404s or reports non-attested forever blocks every later epoch, and "end the window earlier" cannot route around it since the next window must start at toBlock+1. The script needs a frozen-data fallback or a recorded exclusion override (low). The --pilot mode reads the right epoch and start, but from one provider only; a stale read plus a veto produces a root for the wrong epoch that propose accepts (info). Non-oracle completions are dropped unlisted, contradicting the README (info).
   7. Late revisions are not deterministic. The result depends on build time and the REVISION_DAYS env var; an epoch built before the revision lands pays the old credit forever and late-credited agents are missed. The builder should wait until every consulted day's receipt is anchored and record its parameters (low). No double payment across epochs is possible via revisions.
   8. New: cross-window duplicate oracle requests are still bonused twice, since dedupe is per run (info).

   • lowBuilder: a permanently unprovable answered request blocks every later epoch; contiguity makes 'end the window earlier' impossible and there is no sanctioned overridepilot/build-tally.mjs:233

     Every uncertain case now refuses the run (exit 2), which is the right default, but four of the refusal branches can be permanent for an honest chain state: (a) the plane API answers 404 for the oracle id in a status-0 Completed uri (verified: GET /oracle/requests/ -> 404; the plane's retention is not under the pilot's control); (b) the API's status is permanently not 'attested' although the Intake completed with status 0 (verified today: /oracle/requests/39cda5f9-453c-4bfa-8f84-d592fb707994 answers status 'disagreed' with a jobId, so a status-0 completion whose plane status later changes is refused forever); (c) a status-0 completion whose uri carries no /oracle/requests/ (line 172); (d) a frozen document with one acceptance entry naming another request (line 215).

     None of these resolve by waiting. The README (pilot/README.md:53) says 'Wait, or end the window earlier; nothing is lost', but ending the window earlier does not route around the request: the contract requires the next fromBlock == toBlock + 1, so the next window starts at or before the unprovable Completed's block and includes it again.

     The published script therefore cannot build any epoch after block B, and the pilot halts until an operator edits the script by hand, which defeats the 'built by a published script from public inputs' claim. The frozen receipts and documents already carry attestation.requestId, so the mapping does not need the live API.

     Fix: (1) fall back to the frozen data when the live API cannot map a request (scan the receipts of the days around the Completed block's timestamp for a document whose every acceptance entry names the request); (2) add an explicit, recorded override (e.g. --exclude :) that moves a request to skipped and is written into tally.json so reviewers can see it during the veto window; (3) correct the README sentence.

   • lowBuilder: 'latest frozen version within REVISION_DAYS' depends on when the builder runs, so two operators get different roots and an epoch built before the revision lands pays the old credit foreverpilot/build-tally.mjs:208

     The loop over k = -1..REVISION_DAYS reads WorkRegistry.latest(jobId(day)) at the current head. Days whose receipt is not anchored yet (the day is not over, or the plane publishes late) answer null and are silently treated as 'no revision', so the result is whatever has been anchored at build time. Nothing requires the window to be old enough for all REVISION_DAYS receipts to exist, and nothing records REVISION_DAYS (an env var), LOOKBACK or the head block in tally.json.

     Consequences: (1) not deterministic: two operators building the same window on different days, or with different REVISION_DAYS, get different roots, so the veto window cannot be used to cross-check a root by rebuilding; (2) an epoch posted before a late credit lands pays the pre-revision agents the whole bonus and the late-credited agents nothing, and because the window is live it can never be recounted (only veto within 24 h hands the window back; retire does not); (3) a credit that shrinks on revision was already overpaid.

     No double payment across epochs is possible (a job is keyed by its Completed block, which lies in exactly one window).

     Fix: refuse to build unless the receipt for day(toBlock) + REVISION_DAYS is anchored (i.e. every day the loop may consult exists on chain, or the day is explicitly absent after the plane's publishing cutoff), record REVISION_DAYS, LOOKBACK, the head block and every receipt hash consulted in tally.json, and state in the README that an epoch's --to should be at least REVISION_DAYS + 1 days old.

     The builder accepts --to = head - 1, one confirmation deep, and the contract only requires toBlock < block.number at inclusion. Both providers are asked for the same range at the same moment, so they agree on a chain that can still be reorganised (mainnet still sees occasional 1-2 block reorgs).

     A Completed event that moves across the toBlock boundary after the logs were read is either paid twice (it was in the tally for epoch N and the canonical chain now has it at toBlock + 1, inside epoch N + 1's window) or never (the canonical chain now has it at toBlock, epoch N's root lacks it, and epoch N + 1 must start at toBlock + 1). The veto window is the only remedy and it needs someone to rebuild and compare within 24 h, which the previous finding shows is not reliable.

     Fix: bound --to by the finalized block (client.getBlock({ blockTag: 'finalized' })) in the builder, and, as defence in depth, require toBlock + FINALITY_DEPTH < block.number in propose() (64 blocks is two epochs of attestations).

     Finding 4 was: a recount that starts LATER than the struck window (250..300 after 201..300) and is vetoed again leaves the floor at 250, losing 201..249. test_consecutiveVetoesLoseNoBlocks narrows only toBlock (101..200 after 101..300), so on the round-one contract floor = last.fromBlock = 101 and the final propose(101, 300) is accepted: the test's assertions would hold on the old code (it fails there only because nextFromBlock() does not exist).

     The fix itself does close the finding, because fromBlock == nextFromBlock makes a narrowed start unrepresentable; verified in test/scratch/RoundTwo.t.sol (test_oldCode_acceptsTheRegressionTestsSequence passes against the 5f40fa0 contract, test_newCode_refusesNarrowedStartAndHandsWindowBack passes against the current one).

   • inforetire() has no guard against a still-payable epoch: 30 days after posting the governor can strand shares mid-batch, and the window is not handed back (trust assumption to record)src/PaidOraclePilot.sol:199

     retire() checks only vetoed, retired and the 30-day delay. It does not require that nothing is payable (for example paid == 0, or no Paid event in the last N days), so a governor can retire an epoch whose remaining batches are merely waiting for fresh feeds or for an agent to bind a seat; a pay() in the mempool when retire lands reverts EpochRetired and those agents lose their shares for good.

     Accounting stays sound: released = total - paid is subtracted once, totalPaid <= totalCommitted <= LIFETIME_CAP holds in every sequence, retire and veto are mutually exclusive in time (30 d vs 24 h), and keeping the retired window counted is the right choice because paid shares of a retired epoch cannot be distinguished from unpaid ones in a recount.

     This is a governor power, consistent with the veto power, and is not a bypass; it should be written in the README's 'Who holds what power' and the operational rule should be: retire only after a final pay() attempt in the same transaction bundle, or after paid == total minus the shares known to be unresolvable. A contract-level option that preserves the design: let anyone call pay() for the retired epoch's already-resolved shares is not possible, so the rule is operational.

Any pay(0, …) afterwards reverts EpochRetired although every share had a resolvable controller.

   • infoBuilder drops non-oracle Completed events with a bare continue, so they are not listed in `skipped` as the README statespilot/build-tally.mjs:169

     pilot/README.md:47-49 says every definite exclusion is 'listed in skipped: not an oracle request, …'. The code records 'not paid in IMD', the status exclusions and duplicates, but a Completed whose Requested action is not oracle.request@… is dropped without a record, so a reviewer rebuilding during the veto window cannot see from tally.json how many Completed events the window had versus how many were classified.

     Fix: skip(action ${actionOf(r.args.action)} is not an oracle request) instead of continue.

     Window with Completed(R, 0, …) whose Requested action is 'premium.job@v1' paid in IMD.

     Actual: tally.json's skipped list and the stage-1 counts do not mention R.

     Expected (README): R listed as skipped with 'not an oracle request'.

   • infoDuplicate-oracle-request dedupe is per run: the same oracle request named by Intake requests completed in two different windows is bonused twicepilot/build-tally.mjs:193

     The round-one fix dedupes by oracle id inside one build. If the plane ever answers two Intake requests with one oracle request (for example deduplicating identical questions) and the two Completed events land in different windows, epoch N and epoch N + 1 each pay the 1.5e18 bonus for the same job's document. The contract cannot see this (leaves carry agent and amount only).

     Fix: carry forward the oracle ids already credited (read previous epochs' published requests.json from their uris, or keep a per-pilot ledger of credited oracle ids) and skip a repeat as a definite exclusion; or decide and document that a second payer of the same answer does earn a second bonus.

     Completed(R1, 0, …, '/oracle/requests/U') at block 150 (window 1..200, epoch 0) and Completed(R2, 0, …, '/oracle/requests/U') at block 250 (window 201..300, epoch 1), both IMD-paid status 0; U's document credits agents {1,2}.

     Actual: epoch 0 pays 0.75e18 each, epoch 1 pays 0.75e18 each again.

     Expected: 'one bonus per oracle request' (README) across the pilot, or a documented exception.

   • info--pilot mode reads epochCount/nextFromBlock/head from the first provider only; a stale provider plus a veto between build and post yields a root for the wrong epoch number that propose() acceptspilot/build-tally.mjs:50

     Logs are cross-checked between two providers; the three state reads are not. The epoch number is baked into every leaf and propose() cannot check it. In the normal case a stale read is caught by WindowNotContiguous, but one state is not: provider 0 answers the state before epoch N was posted (epochCount N, nextFromBlock X), while on chain epoch N (X..Y) was posted and then vetoed, which sets nextFromBlock back to X.

     The builder produces leaves (N, agent, amount) with fromBlock X; propose(root, total, X, Y') is accepted as epoch N + 1; every pay() reverts BadProof; the epoch has to be retired after 30 days and its window X..Y' is lost.

     Fix: read the pilot state from both clients and require agreement (as logs are), and/or give propose() an expectedEpoch argument it compares with _epochs.length, so a mismatched build cannot be posted.

     Provider 0 lags: readContract(epochCount) = 3, readContract(nextFromBlock) = 1000.

     Chain: epoch 3 (1000..1500) posted at T and vetoed at T + 1 h, so epochCount = 4, nextFromBlock = 1000.

     Build: leaves (3, agent, amount), fromBlock 1000, toBlock 1600. propose(root, total, 1000, 1600, uri) succeeds as epoch 4 (fromBlock matches). pay(4, …) with the published proofs: BadProof for every leaf.

     Expected: the build refused (providers disagree) or the post refused (epoch mismatch).

   Answers to the eight questions

   1. Fixes. All ten fixes close their findings as described. Two variants survive: round-one finding 2 asked that the floor fall back to a retired epoch, which was not done (finding below), and round-one finding 10's dedupe is per run only (finding below). The regression tests cannot be run on round-one code at all: the file uses the three-argument constructor and the new functions and errors, so it does not compile there. The "fails on old code with Panic 0x11" claim is unverifiable from the tree. Reported as info.
   2. Contiguity. Correct in every sequence I tried, including veto, narrower recount, second veto, and a retire in between. The "only the latest epoch can be vetoed" assumption is airtight: epoch N+1 exists only if 6 days passed since N was posted, and N's veto closes after 24 h. Only propose and veto write the floor.
   3. retire(). It cannot release more than committed, since paid never exceeds total and a retired epoch refuses pay. The minted total stays under the lifetime cap through any order of pay and retire. Two defects: a retired epoch that paid nothing and is still the latest loses its window for no reason (low), and the governor can cut off a valid epoch mid-batch at day 30, which is an undocumented power (info).
   4. controllerOf. No remaining answer reverts the batch. Trailing words are accepted, a dynamic-encoded answer is skipped, a 64-byte ownerOf answer is skipped. No well-formed ERC-721 binding is wrongly rejected.
   5. toBlock < block.number. An honest poster is never blocked. The gap is finality: the builder accepts a window ending at head minus one, so a one-block reorg after the log read can make a Completed event be paid twice across two epochs or not at all (low).
   6. Builder. Every uncertain case now refuses. A refusal can become permanent when the live API loses a request forever, and the builder offers no auditable override although the frozen documents carry the mapping (low). Non-oracle requests are dropped without a record, contrary to the README (info). The pilot mode reads the right epoch and window start.
   7. Late revisions. A build before the revision days have elapsed silently uses the old document, because an unanchored day is indistinguishable from an empty one. Late-credited agents are never paid and the root is not reproducible later. Today's receipt anchor reads zero, confirming the state. An epoch should wait until the last answer day plus REVISION_DAYS is anchored (low). No double payment is possible from revisions.
   8. New. Nothing critical or high. The dust from floor division (69 wei on the dry run) is harmless.

   Scope and limits. I covered the contract and builder in depth with the math, boundary and numerical-gap passes, plus the control-flow sequences the questions name. The offline 780-test suite was not re-run for time. No contract files were changed; test/scratch holds my scratch test and the findings generator, neither of which is kept.

   • lowBuilder: an epoch built before REVISION_DAYS have elapsed reads the pre-revision frozen document; the root depends on build time, late-credited agents are never paid, and a later rebuild gives a diffepilot/build-tally.mjs:204

     The revision loop reads receipts for days D-1..D+REVISION_DAYS and keeps the LAST leaf found. receipt(d) returns null when WorkRegistry.latest(jobId(d)) is zero (line 137), and a null receipt is treated exactly like 'no leaf that day'. A day whose receipt is not anchored YET is therefore indistinguishable from a day with nothing, so a build run on D+1 silently takes version 1 of a job that the plane revises on D+2 (the split-panel late credit that commit 953d7c7 exists for).

     Nothing in the builder requires the window's last answer day + REVISION_DAYS to be anchored, and the README's 'rebuildable by anyone' claim fails: two operators running the same --pilot/--to on different days get different roots.

     Because windows are contiguous and an epoch's window is consumed once posted, the agents credited only in version 2 are never paid by any epoch (no double payment: the builder is keyed on Completed events, not receipts, so a job re-listed in a later receipt is not counted again). Live state at review time (2026-10-29): latest(jobId('2026-10-29')) is 0x00..00 while 10-26, 10-27, 10-28 are anchored, so a build today of a window ending on 10-28 reads days 10-29..10-31 as empty.

     Fix: before stage 3, compute the UTC day of the latest Completed in the window and refuse (exit 2) unless receipt(addDays(lastDay, REVISION_DAYS)) is anchored (or at least unless that day is in the past and every day in the range that is in the past is anchored); treat a zero anchor for a past day as 'not proven yet', not as 'no leaf'. Record in tally.json the receipt hashes of every day read so a verifier reproduces the same choice.

     whole finding

     State: oracle request U answered on chain (Completed status 0) at block B in the window, attestedAt day D; the plane's receipt for D lists job J with documentHash H1 whose oracleAcceptance names agents {a1, a2}.

     On D+1 the operator runs node build-tally.mjs --pilot <pilot> --to <head-1>: receipt(D+1), receipt(D+2), receipt(D+3) read latest() == 0 and return null, found = {day: D, documentHash: H1}, shares a1 = a2 = 0.75e18, root R1, posted as epoch N.

     On D+2 the plane anchors receipt D+2 listing J again with H2 naming {a1, a2, a3, a4}.

     Expected: a3 and a4 get 0.375e18 each (and a1, a2 0.375e18), or the build waits.

     Actual: a1 and a2 are paid 0.75e18 from R1; a3 and a4 are never paid because blocks <= toBlock cannot be counted again (propose reverts WindowNotContiguous); a verifier running the same command on D+4 computes root R2 != R1 and cannot tell an early honest build from a wrong root.

     whole reproduction

   • lowBuilder: a request answered on chain whose oracle id the plane's live API no longer maps refuses every later epoch forever; there is no auditable override and the mapping is rebuilt from a mutable serpilot/build-tally.mjs:197

     Stage 2 maps an oracle request id to its job only through GET api.imd.fun/oracle/requests/.

     A 404 (getJson returns null) or a status other than 'attested' is a refusal, which is the right default, but it is unconditional and has no expiry: if the live record is gone for good (retention purge, a request created against another plane environment, a request the plane re-scored to 'disagreed' after completing it with status 0), the Completed event stays in the window, the window cannot be ended before it (toBlock >= fromBlock and the event may sit at nextFromBlock itself), and every later epoch is blocked: the pilot's remaining lifetime budget is stuck with no on-chain error.

     The only way out is to hand-edit the published script, which breaks the 'built by a published script from public inputs' trust statement in the contract NatSpec. The frozen data already carries the mapping: every acceptance entry's document.oracle.attestation.requestId is the bytes32 of the oracle request id, so the job can be found by scanning the leaves of the receipts for the Completed block's day +-REVISION_DAYS without the live API.

     Fix: (a) fall back to that scan when the live API answers 404/non-attested, and (b) add an explicit --exclude [,...] flag whose use is written into tally.json ('excluded', with the reason) so an override is visible to anyone checking the root; without a flag, keep refusing.

     whole finding

     Inputs: Intake Requested(R, payer, 'oracle.request@oracle-1', ..., asset IMD, amount 1e18) and Completed(R, status 0, hash, 'https://api.imd.fun/oracle/requests/', true) at block B with B == nextFromBlock().

     GET /oracle/requests/ answers 404 permanently.

     Run: node build-tally.mjs --pilot <pilot> --to B+1000 -> stage 2 refuse('the plane names no job for it (yet)'), exit 2, nothing written.

     Any --to >= B gives the same result; --to < B is refused by line 64 (toBlock < fromBlock).

     Expected: a documented, auditable path to prove U from the frozen receipts, or to exclude it visibly.

     Actual: no epoch can ever be posted again.

   • lowBuilder: 'one bonus per oracle request' is enforced per run only; two IMD-paid Intake requests naming the same oracle request in different windows pay the 1.5 imdUSD bonus twice (cross-window variant pilot/build-tally.mjs:193

     The seen set lives for one run. Round one's finding 10 described two Completed events naming the same oracle request; the fix deduplicates them only when both fall inside the same window.

     If Intake request R1 names oracle request U and completes at block 150 (epoch N, window 100..199) and R2 names U and completes at block 230 (epoch N+1, window 200..299), U's frozen document passes the attestation check both times (it compares the ORACLE id, not the Intake id) and each of U's agents receives 2 x (1.5e18 / n).

     Fix: before counting U, query Completed logs on the INTAKES from fromBlock - LOOKBACK to fromBlock - 1 and skip any oracle id already named by an earlier IMD-paid status-0 completion (record it in skipped as 'already counted in an earlier window'); or carry forward the previous epochs' requests.json oracle ids.

     Epoch N: Completed(R1, 0, .., '/oracle/requests/U') at block 150, IMD-paid, attested, document agents {a1, a2} -> shares a1 = a2 = 0.75e18, posted and paid.

     Epoch N+1: Completed(R2, 0, .., '/oracle/requests/U') at block 230, IMD-paid -> stage 2 seen is empty, U is credited again: a1 = a2 = 0.75e18 again.

     Expected (README lines 47-49, 'once per oracle request'): R2 skipped as a duplicate.

     Actual: 3.0 imdUSD minted for one job.

   • lowBuilder accepts --to == head - 1, so a one-block reorg after the log read makes the posted root count a Completed event that is no longer canonical, or miss one that moved in; the moved event is then pilot/build-tally.mjs:63

     Both the builder (toBlock < head) and the contract (toBlock < block.number) only require the window to end before the current block, so an honest poster is never blocked (verified: propose accepts toBlock == block.number - 1 and refuses block.number, test/scratch/PilotRound2.t.sol::test_toBlockBoundary). But the logs are read at 'latest' and nothing requires the window to be finalized.

     The two-provider agreement check catches a provider that is behind, not a reorg that happens after both answered. On mainnet, one-block reorgs still occur. If block head-1 holds Completed(R) and is reorged out after the read, the tx is re-included at block >= head: epoch N (window ..head-1) pays R from a block that no longer exists, and epoch N+1 (window head..) finds Completed(R) again and pays it a second time.

     The reverse (an event reorged INTO head-1 after the read) is paid by neither epoch.

     Fix: refuse unless toBlock <= (await client.getBlock({blockTag: 'finalized'})).number (about 2 epochs, ~13 min behind head), and read logs with that bound; the contract needs no change.

     whole finding

     head = H. node build-tally.mjs --pilot <pilot> --to H-1: logs read from both RPCs include Completed(R) at block H-1; root R1 built with U's agents, posted (propose accepts because H-1 < block.number at inclusion).

     Block H-1 is then reorged; the Intake completion tx lands in block H+1.

     Next epoch: nextFromBlock == H, window H..H+k includes Completed(R) at H+1, stage 2 credits U again.

     Expected: each Completed event counted exactly once.

     Actual: U's agents paid twice across two epochs (or, in the opposite reorg direction, not at all).

   • lowretire() keeps the window counted even when nothing of the epoch was ever paid and it is the latest epoch, so the paid work in a mistaken epoch's window is lost although a safe recount was possiblesrc/PaidOraclePilot.sol:200

     Round-one finding 2 asked for two things: release total - paid, and let the floor fall back to the epoch. The fix does the first only. The NatSpec says 'its window stays counted: a correct recount of it is not possible after this', which is true once any share has been paid (a recount would double pay) or once a later epoch exists (contiguity).

     It is not true in the case retire() was written for: a mistaken root (wrong --epoch, typo) for which every pay() reverted BadProof, paid == 0, and no later epoch was posted. There the window can be handed back exactly as veto() does, with no double-payment risk, and the bonus for every paid request in it is preserved instead of lost.

     With the contract as it is, the operator's only recovery for a wrong root that the Safe missed in its 24 h window is to lose the window's work for good.

     Fix: in retire(), if (e.paid == 0 && epoch == _epochs.length - 1) nextFromBlock = e.fromBlock; (and document that a retired-with-payments epoch stays counted).

     whole finding

     Poster posts root built with --epoch 7 (leaves hash epoch 7) as epoch 0 over blocks 100..199, total 2e18.

     After 30 days governor calls retire(0): totalCommitted == 0, epochs(0).paid == 0.

     Poster then proposes a corrected root for the SAME window 100..199 -> reverts WindowNotContiguous(200).

     Expected: a recount of a window from which nothing was paid is accepted.

     Actual: the Intake-paid requests completed in blocks 100..199 can never be bonused.

   • inforetire() is not limited to unpayable epochs: 30 days after posting the governor can cut off a live epoch between two payment batches, stranding valid shares (trust power to record; also reachable whensrc/PaidOraclePilot.sol:199

     The only gate is time. An epoch whose shares are valid and whose batches are being submitted around day 30 can be retired between batch 1 and batch 2; batch 2 then reverts EpochRetired and the released cap can be re-posted to other recipients by a later epoch. The same applies when earn() refused for 30 days because the feeds were stale or disagreed: the epoch looks 'unpaid' but is not unpayable.

     The governor can already veto (within 24 h) and appoint the poster, so this is a documented-class power rather than a bypass, but it is not written down (NatSpec says 'for an epoch that cannot be paid').

     No accounting breaks: released == total - paid, totalPaid <= totalCommitted <= LIFETIME_CAP holds through any order of pay/retire (checked in test/scratch/PilotRound2.t.sol::test_lifetimeCapAfterRetire).

     Suggested: state the power in 'Who holds what power', or require that no pay() of the epoch succeeded in the last VETO_WINDOW (a lastPaidAt per epoch) before retire.

   • infoRound-one regression tests cannot run on the round-one code and need a mainnet fork: the 'fails on old code with Panic 0x11' claim is not reproducible from the file, and the offline suite has no pilottest/fork/PaidOraclePilot.t.sol:52

     RESOLUTION.md states that test_windowCannotEndInTheFuture 'fails on old code with Panic 0x11' and test_malformedBindingSkipsOneShareNotTheBatch 'fails on old code: whole batch reverts'. The test file does not compile against 5f40fa0: it uses the three-argument constructor (line 52; the old one is constructor(address,address)), nextFromBlock(), retire(), WindowInFuture, WindowNotContiguous, EpochRetired and TooEarlyToRetire, none of which exist there.

     So the regression claim can only have been checked with ad-hoc variants that are not in the tree. Every fix is nevertheless pinned by the current tests, and I confirmed by reading the old code that each would have failed for the stated reason (toBlock + 1 in checked uint64 -> Panic 0x11; abi.decode into uint8/address -> revert). Separately, all pilot tests live in test/fork and skip without --fork-url, so forge test offline exercises none of the pilot.

     Suggested: an offline unit test with a mock vault/adapter (the pattern in test/scratch/PilotRound2.t.sol works) so the contract's own arithmetic and sequencing are checked on every run.

   • infoREADME says non-oracle Intake requests are 'listed in skipped'; the builder drops them without a record, so the published tally cannot show that a request was excluded on that groundpilot/build-tally.mjs:169

     pilot/README.md lines 47-49: 'Excluded by definition, and listed in skipped: not an oracle request, not paid in IMD, status 1 or 2, a second Intake request naming the same oracle request.' Line 169 continues before skip(), so a Completed event whose action is not oracle.request@ never appears in tally.json or requests.json. A verifier comparing the Intake's Completed count with the tally's candidate + skipped counts sees a difference it cannot attribute.

     Fix: skip('not an oracle request') instead of a bare continue.

     Window containing Completed(R, 0, ..) whose Requested action is 'premium.job@premium-1' (not an oracle request).

   Answers to the eight questions

   1. Fixes and regressions. All ten round-one findings are closed, including their variants. Two test notes: the finding-4 regression narrows the window's end, a sequence the round-one code also accepted, so it passes on both versions and does not pin the finding (the later-start variant is closed by contiguity, not the veto reset). The toBlock regression fails on the old code with "did not revert", not the Panic RESOLUTION.md names. Info.
   2. Contiguity. Correct in every sequence I ran: veto, wider recount, veto, live recount, retire of an old epoch, veto of the latest. The "only the latest epoch is inside its window" assumption is airtight: a new epoch needs 6 days after the previous one's posting, including vetoed ones, and the veto window is 24 h. Clear no.
   3. retire. Cannot release more than committed, cannot pay anything, and total minted stays under the lifetime cap through any sequence (retired epochs keep exactly their paid amount committed). It can strand a payable epoch's remaining batches at day 30, a governor power the README does not state. Keeping the window counted is the right default since part of it may be paid. Info.
   4. controllerOf. Clear no. Extra trailing words, other standards, EOA token contracts and odd-length ownerOf answers all skip one share; a well-formed ERC-721 binding resolves.
   5. toBlock < block.number. No honest poster is ever blocked. The real gap is the other way: the builder accepts head - 1 with no finality depth, so a reorg after the build changes the counted set permanently. Low.
   6. Builder skips vs refusals. Every uncertain case now refuses. "Not an oracle request" is dropped silently rather than listed as README says. Refusals can be permanent, and with contiguous windows one permanently unprovable request stops every later epoch with no override. The operator needs an explicit, recorded exclusion flag. --pilot reads the right values but from one provider only. Low.
   7. Late revisions. This is the medium finding. A receipt not yet anchored counts as "job absent", so the root depends on build time: a build before day+REVISION_DAYS pays an earlier version and the revision's agents are lost once the window is counted, and two operators get different roots. Revisions are real: job 569e4f4c… appears in both the 2026-10-13 and 2026-10-14 receipts with different documents (empty, then three agents). An epoch should wait REVISION_DAYS, and the builder should enforce it. REVISION_DAYS and LOOKBACK also change the root but are not recorded in tally.json.
   8. New. The constructor does not bound firstFromBlock; type(uint64).max makes every propose impossible with no setter. Info.

   No critical or high findings, so no proof files were attached. The specialty passes (Access Control, Trust Gap, Asymmetry, with execution-trace reads of the builder) were my own; no helpers ran.

   • mediumBuilder: 'latest frozen version within REVISION_DAYS' is read at build time, so the root depends on WHEN it is built; a receipt not yet anchored is treated as 'job absent' and an earlier version is papilot/build-tally.mjs:204

     Commit 953d7c7 makes the builder take the LATEST receipt within REVISION_DAYS (default 3) of the answer day that lists the job. receipt(d) returns null when WorkRegistry.latest(dayJobId(d)) is zero (line 137), and a null receipt is simply 'no leaf', not a refusal. So a build made on day D+1 for a job answered on day D sees receipts D-1, D and (if anchored) D+1 and treats D+2 and D+3 as absent; it takes the version anchored so far and writes a root.

     The same window built on D+4 sees the revised leaf in D+2 or D+3 and produces a DIFFERENT root.

     Consequences: (a) same window, two operators, two roots, so the governor's rebuild-and-compare in the 24 h veto window cannot distinguish an honest root from a wrong one (and will veto an honest root built a day earlier, or accept one that misses the revision); (b) the epoch is posted and the window counted, so agents added by the late revision are never paid (the window cannot be recounted after the veto window, and retire keeps the window counted), and agents removed by a re-scoring are overpaid; (c) a job whose FIRST frozen version has an empty oracleAcceptance refuses the run (entries.length == 0 -> 'do not all answer this request'), and the same run succeeds a day later, so the refusal/success outcome itself is time dependent.

     Late revisions are real on chain today: scanning the anchored receipts for 2026-10-12..21 (10 receipts, 1066 jobs) finds job 569e4f4c-dc58-4e3f-9c9e-bc09837092a8 in the 2026-10-13 receipt (document 0x9559ecc8a5..., oracleAcceptance empty) AND in the 2026-10-14 receipt (document 0x1c3fb8d58d..., agents 51046, 51553, 52713, attestation.requestId 0xd73223d054b94b91...). The README's 'two operators, same window, same root' property and the design claim 'nothing is lost' both fail.

     Fix: make the read deterministic in time: refuse the run while any receipt day in [day-1, day+REVISION_DAYS] for any counted job could still be anchored (e.g. require head block timestamp >= end of UTC day (day+REVISION_DAYS) plus the plane's anchoring lag, or require every receipt in that range to be anchored), and document that an epoch must wait REVISION_DAYS after its last answer before it is built.

     whole finding

     State: Intake Completed(status 0, uri /oracle/requests/U) at a block inside the window; the plane maps U to job J attested on day D; the receipt for D lists J with document v1 (agents {A,B}); the plane credits a split panel late and the receipt for D+2 lists J with document v2 (agents {A,B,C}).

     Run 1 on day D+1 (receipt D+2 not anchored yet): receipt(D+2) -> null, found = v1 from day D, agents {A,B}, root R1 written and posted; nextFromBlock moves past the window.

     Run 2 on day D+4 (same --from/--to, same REVISION_DAYS=3): found = v2 from day D+2, agents {A,B,C}, root R2 != R1.

     Expected: identical roots for identical windows, and C paid 0.5 imdUSD.

     Actual: R1 is posted, C is never paid (window counted, no recount after 24 h), and a governor rebuilding on day D+2 gets R2 and sees the honest epoch as wrong.

     Live instance of a revised job: WorkRegistry 0xb6d0a187b050fa5bb0b87033a203f37becf4a775 latest(dayJobId('2026-10-13')) and latest(dayJobId('2026-10-14')) both list jobId 569e4f4c-dc58-4e3f-9c9e-bc09837092a8 with different documentHash values (0x9559ecc8a5... with 0 acceptance entries, 0x1c3fb8d58d... with 3).

     For that job a build on 10-13 refuses (empty entries) and a build on 10-14 pays three agents: two different outcomes from the same chain window.

     whole reproduction

   • lowBuilder: a request that can never be proven blocks every later epoch forever (contiguity + no override); the operator has no sanctioned way outpilot/build-tally.mjs:233

     Round-one fix 7 correctly turned every uncertain case into a refusal (exit 2).

     But several refusals are permanent, not 'wait': a status-0 Completed whose uri never names an oracle request (line 172); an oracle id the live API answers 404 for permanently (deleted, retention, renamed) (line 197); a status-0 request the plane permanently reads as anything but 'attested' (line 198); a job that is never anchored in any receipt in [day-1, day+REVISION_DAYS] (line 210); a frozen document with one acceptance entry answering another request (line 215).

     Because propose() requires fromBlock == nextFromBlock and toBlock >= fromBlock, the window containing such a request cannot be skipped: 'end the window earlier' only works if the request is not at or before the first block that has to be covered. Once a permanently unprovable request sits in the blocks the next epoch must start from, no epoch can ever be built with this script: the pilot's remaining lifetime budget is dead, with no on-chain defect.

     The plane, not the poster or payer, decides every one of those fields, so one bad record from the plane stops the pilot.

     What the operator should be able to do, and today cannot: exclude the request explicitly and visibly, e.g. --exclude with the reason written into tally.json's skipped so the governor sees the exclusion during the veto window; and fall back to rebuilding the oracleId -> job mapping from frozen data (every leaf's document carries attestation.requestId) so a live-API 404 is not fatal.

     whole finding

     Inputs: Intake Requested(R, payer, action 'oracle.request@oracle-1', asset IMD, amount 1e18) at block B-10 and Completed(R, status 0, hash, uri 'https://api.imd.fun/oracle/requests/not-a-uuid', true) at block B, with B == nextFromBlock (the first uncounted block). node build-tally.mjs --pilot P --to T for any T >= B: stage 1 refuses ('answered, but the uri names no oracle request'), exit 2, nothing written. --to B-1 is refused by the script (toBlock < fromBlock) and by propose() (InvalidRoot).

     Expected: a documented, logged way to exclude R.

     Actual: no epoch can be posted again; epochCount() stays constant while paid work after B accumulates uncounted.

     Same outcome when GET /oracle/requests/ answers 404 permanently for a status-0 Completed (getJson returns null -> refuse at line 197).

   • lowBuilder: REVISION_DAYS and LOOKBACK change the root but are not recorded in tally.json, so a published tally is not reproducible from its own inputspilot/build-tally.mjs:31

     The root is a function of the window, the chain, the frozen documents AND two environment inputs: REVISION_DAYS (which versions are eligible) and LOOKBACK (whether a Requested is found at all; a miss is a refusal, so it changes refuse/success). Neither is written to the summary at lines 260-267, which records bonusPerRequest and the script path as the reproducibility inputs.

     A governor rebuilding during the veto window with the default values gets a different result from a poster who exported REVISION_DAYS=0 or 7, and tally.json gives no hint why.

     Verified on the documented dry-run window (26194146..26215746): REVISION_DAYS=3 builds root 0xebaa554958d237fee592d2f71f74d97de1673dc0d03b14e65f4e3bb8a113d824 (98 requests, 210 agents); REVISION_DAYS=0 on the same window refuses with two requests (oracle 1c894d82-d508-4772-96da-5c1da4827f58 and 166507c1-1be6-4b95-8057-ee6ec5135781) 'job not in the receipts around 2026-10-14'.

     Fix: pin both as constants in the script (or require them as explicit flags) and write them into tally.json next to bonusPerRequest.

   • lowBuilder --pilot mode reads epochCount() and nextFromBlock() from ONE provider, unlike logs which must agree across two; a wrong epochCount yields a root the contract accepts but can never paypilot/build-tally.mjs:50

     Round-one fix 2/3 moved --epoch and --from from operator typing to chain reads, but the reads go to clients[0] only (mevblocker by default), with no cross-check against clients[1] and no block tag, while every log read is required to agree between both providers precisely because a public RPC can answer wrongly without erroring. A wrong nextFromBlock is harmless (propose() reverts WindowNotContiguous).

     A wrong epochCount is not: the epoch number is hashed into every leaf and the contract cannot verify the root, so a root built for epoch N-1 (stale provider, or a provider serving a wrong state) is accepted as epoch N; every pay() reverts BadProof; the epoch burns one 6-day slot, its window (never recountable after the veto window) and 350 imdUSD of lifetime cap until the governor can retire it 30 days later.

     This is exactly the round-one 'mistyped --epoch' failure with the typo moved into the RPC.

     Fix: read both values from every client at the same block number and require agreement; also warn when the latest epoch is still inside its veto window (a veto would move nextFromBlock back and invalidate the build).

     whole finding

     State: pilot has 3 epochs (epochCount()==3, nextFromBlock()==1001). clients[0] answers epochCount()==2 (stale or wrong), nextFromBlock()==1001.

     Build: leaves (2, agentId, amount), root R2, tally.json says epoch 2.

     Poster calls propose(R2, total, 1001, 1500, uri): accepted as epoch 3 (nothing checks the leaves).

     After 24 h pay(3, ids, amounts, proofs) -> BadProof for every share; veto window closed; retire(3) only after 30 days; blocks 1001..1500 can never be recounted.

     Expected: the build refuses when the two providers disagree, as it does for logs.

     whole reproduction

   • lowBuilder accepts toBlock = head - 1 with no reorg depth; a reorg between build and post changes the window's Completed set and the counted window then permanently omits the re-included workpilot/build-tally.mjs:62

     Question 5: an honest poster can always post (block.number only grows, so toBlock < block.number at posting holds for any toBlock < head at build time), and a window ending at the head is refused by both the script and propose(), so there is no liveness problem. The correctness problem is the other direction: the script lets the window end one block below the head it read, and reads logs for those blocks with no finality requirement.

     The two-provider agreement check does not help when both providers see the same pre-reorg block.

     If a short reorg after the build drops or moves a Completed event that was in blocks near toBlock, the posted root reflects the orphaned history; since nextFromBlock = toBlock + 1 and the window is never recounted after 24 h, a request re-included inside the window by the canonical chain is never bonused, and one that moved out of the window is bonused although its Completed is now in the next window (it would then be counted again there, double paying).

     Fix: cap --to at the finalized block (client.getBlock({blockTag:'finalized'})) or at head minus a fixed depth, and record the block hash of toBlock in tally.json so a rebuild detects a reorg.

     whole finding

     Head H. node build-tally.mjs --pilot P --to H-1: accepted.

     Blocks H-1 contains Completed(R, 0, ..., '/oracle/requests/U') in the builder's view; the root excludes nothing.

     A 2-block reorg replaces H-1 and H; the canonical H-1 does not contain R's Completed, the canonical H+1 does.

     The poster posts the pre-reorg root with toBlock H-1: accepted (H-1 < block.number).

     Next epoch starts at H and counts R again (its Completed is now at H+1): U paid twice.

     Mirror case (Completed enters the window after the build): U never paid.

     Expected: --to limited to finalized blocks so the window's events cannot change after the build.

   • infoRegression test for round-one finding 4 does not exercise the finding's variant: its sequence is also accepted by the round-one code (the variant is closed by contiguity, not by the veto reset)test/fork/PaidOraclePilot.t.sol:287

     Finding 4 was: a vetoed window [201,300] recounted with a LATER START [250,300], vetoed again, leaves blocks 201..249 uncountable because the old floor was last.fromBlock = 250. test_consecutiveVetoesLoseNoBlocks narrows the END instead ([101,300] -> [101,200]); under the old rule the floor after the second veto is epochs[2].fromBlock = 101, so the final propose(101,300) was accepted by the round-one code as well.

     Replayed against the round-one contract (git show 5f40fa0:src/PaidOraclePilot.sol compiled as OldPaidOraclePilot): the test's sequence passes on the old code; the finding's sequence (epoch 2 = [250,300]) reverts WindowNotAfterPrevious on the old code and WindowNotContiguous(101) on the new one. So the regression does not fail on the old code for the finding's reason; it passes there.

     Also, RESOLUTION.md says test_windowCannotEndInTheFuture 'fails on old code with Panic 0x11'; on the old code the first expectRevert(WindowInFuture) fails with 'call did not revert as expected' because propose(.., 1, type(uint64).max) is accepted, and the Panic only appears on the NEXT propose.

     Neither affects the fixes themselves, which are correct (verified: fromBlock == nextFromBlock plus veto reset keeps nextFromBlock equal to the last live epoch's toBlock + 1 across veto, recount, veto, retire).

     Fix: make epoch 2 in the test start at 250 (now expected to revert WindowNotContiguous(101)) so the test pins the variant.

     whole finding

     On the round-one contract: propose(root,3e18,1,100); warp 6d; propose(root,3e18,101,300); veto(1); warp 6d; propose(root,3e18,101,200); veto(2); warp 6d; propose(root,3e18,101,300) -> ACCEPTED (epoch 3).

     The new test asserts exactly this acceptance, so it passes on both versions.

     With epoch 2 = propose(root,3e18,250,300) instead: old code reverts the final propose with WindowNotAfterPrevious (the finding); new code refuses epoch 2 itself with WindowNotContiguous(101).

   • infoConstructor does not bound firstFromBlock; a value at or above the chain head delays the pilot and type(uint64).max makes every propose() impossible with no settersrc/PaidOraclePilot.sol:156

     New in 548b006: nextFromBlock is seeded from a constructor argument with no check. propose() needs toBlock >= fromBlock == nextFromBlock and toBlock < block.number, so firstFromBlock > block.number only waits for the chain, but firstFromBlock = type(uint64).max (or any value the chain will not reach while the pilot is wanted) makes every propose revert (InvalidRoot for toBlock < fromBlock, WindowInFuture for toBlock == max) and there is no governor setter for nextFromBlock.

     The pilot can still be installed through the 96 h Parameters timelock before anyone notices. Deployment-time only, one shot, and visible in the first propose attempt; a require(firstFromBlock <= block.number) or deploying from a script that reads the head closes it.

   • inforetire() is a governor power over any 30-day-old epoch, including one being paid in batches; README describes it only as 'an epoch that cannot be paid'. Accounting is sound; the power should be statedsrc/PaidOraclePilot.sol:199

     Question 3 answers. retire() cannot release more than committed: released = total - paid, paid <= total, and the epoch's total is in totalCommitted exactly when it is neither vetoed nor retired, so the subtraction never underflows (veto and retire are mutually exclusive in time: < 24 h vs >= 30 days, and each checks the other's flag). totalPaid <= totalCommitted <= LIFETIME_CAP holds through any sequence because a retired epoch keeps exactly its paid amount in totalCommitted (verified offline: 9 epochs of 350 with two unpaid epochs retired at day 30+, 7 paid in full, totalPaid 2450 <= 3000, no OverLifetimeCap).

     It cannot pay anything. What it CAN do beyond the README: strand shares of a payable epoch. Any epoch 30 days old can be retired regardless of whether shares remain payable, so an epoch paid in batches around day 30 (feeds stale for weeks, Unpayable agents who bind late) loses every unpaid share the moment the governor retires it, and a pay() in the same block ordered after retire reverts EpochRetired.

     That is a denial of payment, not theft, consistent with the governor's veto power, but it is not written down in NatSpec or README, which both say retire is for epochs that cannot be paid. Leaving a retired epoch's window counted is the right default: part of it may have been paid, so handing the window back would double pay; the only safe hand-back would be paid == 0 AND the epoch is the latest, which could be offered as an optional improvement, not a fix.

     whole finding

     Epoch 0 posted (leaves agent 1: 1e18, agent 2: 2e18, total 3e18).

     Day 30: pay(0,[1],...) pays agent 1.

     Governor: retire(0) -> totalCommitted falls to 1e18. pay(0,[2],...) -> EpochRetired; agent 2's 2e18 is never paid though its proof is valid and its controller resolves.

   • infoBuilder: 'not an oracle request' completions are dropped silently although README says they are listed in `skipped`; duplicate oracle ids are deduplicated within one window onlypilot/build-tally.mjs:169

     README line 47-49 says every definite exclusion is 'listed in skipped' and names 'not an oracle request' first; the code continues without pushing to requests, so neither tally.json's skipped list nor the stage-1 count shows them. A reviewer comparing Completed counts against the tally (as round one did: 117 Completed vs 103 oracle requests) cannot account for the difference from the published files.

     Separately, the one-bonus-per-oracle-request rule (line 193) uses a seen set local to the run: a second Intake request naming the same oracle id whose Completed lands in a LATER window is paid again. Both are plane-written-data robustness notes (every oracle id in the dry-run window is distinct).

     Fix: skip('not an oracle request') instead of continue; carry the previous epochs' oracle ids (from their published requests.json) into seen, or accept and document the per-window scope.

     Window with Completed(R1, 0, .., 'https://api.imd.fun/premium/jobs/..') whose Requested action is 'premium.job@v1': the run's stage-1 line reports {candidate: n} with no skip entry and tally.json.skipped omits R1; README promises it listed. Cross-window: Completed(R1,0,'/oracle/requests/U') at block 100 (epoch 0 window 1..100) and Completed(R2,0,'/oracle/requests/U') at block 150 (epoch 1 window 101..200): U's agents receive 1.5 imdUSD in epoch 0 and again in epoch 1.

   Answers to the eight questions

   1. Every contract fix closes its finding and the variants. Two regression claims do not hold: the finding-4 test narrows the end, not the start, and the round-one contract accepts its whole sequence. The "Panic 0x11 on old code" claim is wrong because the old code accepts the max toBlock and panics only on the next propose. Builder fixes have no automated regression (info).
   2. Contiguity is correct in every sequence I tried, including veto, recount, veto, retire. The "only the latest epoch is inside its window" assumption is airtight: the 6-day gap is measured from the latest epoch whether or not it was vetoed, and timestamps are monotonic.
   3. retire() cannot over-release, pay anything, or break the lifetime cap. It can strand valid shares of a payable epoch mid-batch (info, trust power to record). Keeping the window counted is wrong in one case: paid is zero and the epoch is the latest, where a safe hand-back was possible (low).
   4. controllerOf is correct. Extra trailing bytes, malformed words, non-ERC-721 standards and short answers all skip one share. No well-formed binding is rejected.
   5. An honest poster can always post. The real defect is the opposite direction: the window can end one block below an unfinalized head, so a reorg can double-pay or drop a Completed event (low).
   6. Every uncertain case refuses. The remaining skips are definite, but "not an oracle request" is dropped without a record despite the README (info). Refusals can become permanent and then block every later epoch because of contiguity, with no recorded override (low). Pilot mode reads the right values but from one provider only, and a stale read across a propose plus veto yields a root propose() accepts but nobody can pay (low).
   7. The latest-version read is not deterministic: unanchored days look like "no revision", so the root depends on when the build runs, late-credited agents are never paid, and the governor cannot cross-check a root by rebuilding. Confirmed on live data. An epoch should wait REVISION_DAYS plus anchoring lag before it is built (medium). REVISION_DAYS and LOOKBACK are also not recorded in tally.json (low).
   8. New in the changes: the unbounded constructor firstFromBlock (info), and a superseded frozen document that the records API no longer serves makes the builder throw instead of refusing cleanly (folded into the medium finding).

   No finding reached high, so no proof files were attached. All 11 snippets were checked against the tree.

   • mediumBuilder: 'latest frozen version within REVISION_DAYS' is read at build time, so the root depends on WHEN the window is built; late credit is missed and two operators get different rootspilot/build-tally.mjs:204

     Commit 953d7c7 takes the LAST leaf found for the job in the receipts of day-1..day+REVISION_DAYS. receipt(d) (line 137) returns null when WorkRegistry.latest(dayJobId(d)) is zero, and the loop treats null exactly like 'the job was not revised that day'. A day not anchored YET is therefore indistinguishable from a day with nothing, and nothing in the builder requires the window's last answer day + REVISION_DAYS to be anchored: the only time rule is toBlock < head (line 63). So the result depends on the wall-clock time of the run.

     1. A build made soon after the window ends (the normal case) reads the ORIGINAL credit of every request answered in the last ~REVISION_DAYS; a revision anchored later (the split-panel late credit this commit exists for) is never paid, because the request is counted only in the window holding its Completed block and the window is consumed once posted (retire does not hand it back). A revision that removes an agent is the reverse: that agent was paid under a superseded version. No double payment across epochs.
     2. Determinism fails: a governor rebuilding one or two days later reads more receipts and gets a different root, so the 24 h veto cannot tell an honest early build from a wrong root, and the README's 'rebuildable by anyone' property does not hold.
     3. The refusal/success outcome is itself time dependent: a first frozen version with an empty oracleAcceptance refuses ('do not all answer this request'), and a superseded document can disappear from the records API, in which case frozenDoc throws an uncaught error (exit 1, not the documented exit 2). Live evidence (2026-10-29, Tenderly RPC): WorkRegistry.latest for 2026-10-26..28 is anchored and for 2026-10-29 is 0x00..00, so a build today of a window ending yesterday reads days 10-29..10-31 as empty. Job 569e4f4c-dc58-4e3f-9c9e-bc09837092a8 (oracle request d73223d0-54b9-4b91-a727-576597042689, attestedAt 2026-10-14T00:43Z, status attested) is listed in the 2026-10-13 receipt (0x7514...7b9a) with documentHash 9559ecc8...85fc, which api.imd.fun/work-records now answers 404 'unknown_record', and in the 2026-10-14 receipt (0xf35c...cff3) with documentHash 1c3fb8d5...9f96 naming agents 51553, 52713, 51046. A build between the Completed on 10-14 and the anchoring of the 10-14 receipt crashes on the 10-13 version (work record not found); a build afterwards pays three agents. Four specialists reported this (permissions, math, economics, flow); merged. Fix (builder only): before stage 3 refuse (exit 2) unless the receipt for addDays(day, REVISION_DAYS) is anchored for every credited request (or the run is past that day plus the plane's anchoring lag), treat a zero anchor for a past day as 'not proven yet'; write every receipt hash read, the head block and REVISION_DAYS into requests.json/tally.json; document in the README that an epoch's --to must be at least REVISION_DAYS + 1 days old.

   • lowBuilder: REVISION_DAYS and LOOKBACK change the root or the refuse/success outcome but are not written to tally.json, so a published tally is not reproducible from its own inputspilot/build-tally.mjs:31

     The root is a function of the window, the chain, the frozen documents AND two environment inputs: REVISION_DAYS (which frozen version of a job is eligible, line 204) and LOOKBACK (whether a Requested event is found at all; a miss is a refusal, line 168). The summary written at lines 260-267 records bonusPerRequest and the script path as the reproducibility inputs but neither of these.

     A governor rebuilding with the defaults during the veto window gets a different result from a poster who exported REVISION_DAYS=0 or 7, and tally.json gives no hint why. Reported by the permissions specialist (with a live dry run: REVISION_DAYS=3 on 26194146..26215746 builds root 0xebaa5549...d824 while REVISION_DAYS=0 refuses two requests). Distinct from the time-dependence finding: its fix is to pin or record the inputs.

     Fix: make both explicit flags or constants and write them (plus the head block and every receipt hash read) into tally.json next to bonusPerRequest.

   • lowBuilder: a paid request that can never be proven blocks every later epoch permanently; contiguity makes 'end the window earlier' a one-time remedy and there is no recorded overridepilot/build-tally.mjs:233

     Round-one fix 7 rightly turned every uncertain case into a refusal (exit 2), but several refusal causes do not resolve by waiting: (a) a status-0 Completed whose uri does not match //oracle/requests/([0-9a-f-]{36})/ (another uri form, or an upper-case UUID, line 163/172); (b) GET /oracle/requests/ answering 404 for good (verified: an unknown id answers 404), or a final status other than 'attested' for a request the Intake completed with status 0 (round one saw 'disagreed' on such ids), lines 197-198; (c) a job absent from every receipt in day-1..day+REVISION_DAYS (a day the plane never anchored, or attestedAt missing so createdAt is used and the job is anchored later than +3), line 210; (d) a frozen document whose acceptance entries do not all name the request, line 215; (e) a receipt leaf whose document the records API no longer serves, where frozenDoc throws (uncaught, exit 1).

     The contract requires fromBlock == nextFromBlock (src/PaidOraclePilot.sol:220) and toBlock >= fromBlock, so a window cannot route around block B: 'end the window earlier' works once (--to B-1), after which nextFromBlock == B and every later run includes B and refuses again.

     The pilot's remaining lifetime budget is then stuck with no on-chain defect; the only ways out are editing the published script (breaking the 'built by a published script from public inputs' statement in the NatSpec), setPoster(0), or a hand-built root. README line 53 ('Wait, or end the window earlier; nothing is lost') is wrong for these cases. Four specialists reported it; merged.

     The frozen data already carries the mapping (every acceptance entry has document.oracle.attestation.requestId), so a live-API 404 need not be fatal.

     Fix: classify refusals as transient or permanent; fall back to scanning the receipts around the Completed block's day for a document whose entries all name U; add an explicit, recorded exclusion input (e.g. --exclude :) written into tally.json's skipped so the governor sees it in the veto window; lower-case the uri before matching; correct the README sentence.

     Actual: no epoch can be posted again; epochCount() stays constant while paid work after B accumulates uncounted.

   • lowBuilder lets a window end one block below an unfinalized head; a reorg after the log read can pay a Completed event twice across two epochs or never, and contiguity makes it uncorrectablepilot/build-tally.mjs:63

     Question 5 answered: an honest poster can always post (block.number only grows, so any toBlock < head at build time satisfies toBlock < block.number at inclusion; verified propose accepts block.number - 1 and refuses block.number). The defect is the other direction: head is getBlockNumber() ('latest'), logs are read at 'latest', and nothing requires toBlock to be finalized.

     The two-provider agreement check catches a lagging provider, not a reorg that happens after both answered. Mainnet still sees occasional 1-2 block reorgs. If a Completed event in block toBlock is reorged out and re-included at toBlock+1 or later, epoch N (built before the reorg) pays it and epoch N+1 (window starting at toBlock+1, seen is per run) pays it again; if an event is reorged INTO the window after the read, neither epoch pays it.

     The posted root is accepted regardless and the window cannot be recounted after 24 h. Anchoring lag of the daily receipts makes this rare but does not prevent it (a request answered just before midnight UTC whose receipt is anchored quickly). Four specialists reported it; merged.

     Fix: bound --to by the finalized block (client.getBlock({ blockTag: 'finalized' }) from both providers) and record toBlock's block hash in tally.json so a rebuild detects a reorg; optionally require toBlock + FINALITY_DEPTH < block.number in propose().

     whole finding

     Head H.

     Completed(R, 0, .., '/oracle/requests/U') is in block H-1 in both providers' view. node build-tally.mjs --pilot P --to H-1: accepted (H-1 < H); U credited in epoch N; the poster posts at block > H (accepted, H-1 < block.number).

     Block H-1 is reorged and the Intake completion lands in block H+1.

     Next build: nextFromBlock = H, window H..H+k contains Completed(R) at H+1, seen is empty, U credited again.

     Expected: each Completed counted once.

     Actual: U's agents receive 1.5 imdUSD twice (or, if the event moved into the window after the read, never).

   • lowBuilder --pilot mode reads epochCount() and nextFromBlock() from ONE provider with no cross-check; a stale read across a propose+veto pair yields a root for the wrong epoch number that propose() acceppilot/build-tally.mjs:50

     Round-one fix 2/3 moved --epoch/--from from operator typing to chain reads, but the reads go to clients[0] only (mevblocker by default), with no block tag and no agreement check against clients[1], while every log read must agree between both providers precisely because a public RPC can answer wrongly without erroring. A wrong nextFromBlock is harmless (WindowNotContiguous).

     A wrong epochCount is not: the epoch number is hashed into every leaf, propose() cannot check it, and a stale provider CAN return a wrong epochCount with a correct nextFromBlock: epoch N (X..Y) is posted and vetoed on chain (nextFromBlock back to X, epochCount N+1) while the provider still serves the pre-propose state (epochCount N, nextFromBlock X).

     The build produces leaves (N, agent, amount) with fromBlock X; propose(root, total, X, Y') is accepted as epoch N+1; every pay() reverts BadProof; the governor can only retire it after 30 days and the window X..Y' is lost for good (see the retire finding). This is round one's 'mistyped --epoch' failure with the typo moved into the RPC. Reported by the permissions and flow specialists; merged.

     Fix: read epochCount, nextFromBlock and head from every client at the same block number and require agreement; warn when the latest epoch is still inside its veto window; optionally give propose() an expectedEpoch argument compared with _epochs.length.

     whole finding

     After 24 h pay(4, ids, amounts, proofs) -> BadProof for every leaf; veto window closed; retire(4) only after 30 days; blocks 1000..1600 can never be recounted.

     Expected: the build refuses when the two providers disagree, as it does for logs.

   • lowretire() never hands the window back, even when paid == 0 and the epoch is the latest, so the paid work in a mistaken epoch's window is lost although a safe recount was possiblesrc/PaidOraclePilot.sol:194

     Question 3: keeping the window counted is right once any share was paid (a recount would double pay) or once a later epoch exists (contiguity). It is not right in the case retire() was written for: a mistaken root (wrong epoch number in the leaves, a typo) for which every pay() reverted BadProof, paid == 0, no later epoch.

     There the window could be handed back exactly as veto() does (nextFromBlock = e.fromBlock) with no double-payment risk, and the bonus for every paid request completed in it preserved. As written, the operator's only recovery for a wrong root that the Safe missed in its 24 h window is to lose that window's work for good. Round-one finding 2 asked for both the cap release and the floor fallback; the fix did the first only.

     Everything else about retire() is sound: released = total - paid never underflows (paid <= total by OverEpochTotal), veto and retire are mutually exclusive in time and each checks the other's flag, totalPaid <= totalCommitted <= LIFETIME_CAP holds through any order of pay/retire/propose (checked in test/scratch/Round2Judge.t.sol::test_retireStrandsOutstandingBatch_capsHold), and an epoch being paid in batches around day 30 cannot release more than its unpaid remainder.

     Reported by the math specialist.

     Fix: in retire(), if (e.paid == 0 && epoch == _epochs.length - 1) nextFromBlock = e.fromBlock; and document that a retired epoch with payments stays counted.

   • inforetire() is a governor power over any 30-day-old epoch, including one still being paid in batches: unpaid valid shares are stranded; NatSpec and README describe it only as 'for an epoch that cannot besrc/PaidOraclePilot.sol:200

     The only gates are the vetoed/retired flags and the 30-day delay. An epoch whose shares are valid and whose batches are being submitted around day 30 (feeds stale for weeks, Unpayable agents who bind late, batches nobody submitted yet) can be retired between batch 1 and batch 2; batch 2 then reverts EpochRetired and those agents lose their shares for good, while the released cap can be re-posted to other recipients.

     Accounting stays sound (released == total - paid; totalPaid <= totalCommitted <= LIFETIME_CAP in every sequence). It cannot pay anything, cannot be used before day 30, and is consistent with the governor's veto power, so this is a trust assumption to record rather than a bypass: it is not in 'Who holds what power' (NatSpec or README), which say retire is for epochs that cannot be paid. Three specialists reported it; merged.

     Suggested: state the power, and either an operational rule (retire only after a final pay() attempt in the same bundle) or a contract guard such as requiring no Paid event in the last VETO_WINDOW (a lastPaidAt per epoch).

   • infoRegression test for round-one finding 4 does not exercise the finding's variant (the round-one contract accepts its whole sequence), and RESOLUTION's 'fails on old code with Panic 0x11' claim is not wtest/fork/PaidOraclePilot.t.sol:287

     Question 1. Every contract fix closes its finding including the variants (verified by reading and by test/scratch/Round2Judge.t.sol: any toBlock >= block.number refused, any gap refused, a recount with a LATER start refused with WindowNotContiguous(101), bit 200 in the address word and 256 in the standard word skip one share). But two regression claims do not hold.

     (a) Finding 4 was: vetoed [201,300] recounted as [250,300] (later START), vetoed again, floor stuck at 250. test_consecutiveVetoesLoseNoBlocks narrows the END instead ([101,300] -> [101,200]); under the old rule floor = last.fromBlock = 101 and the final propose(101,300) was accepted by the round-one code too.

     Compiled 5f40fa0's contract as OldPaidOraclePilot and replayed: test_oldCode_acceptsTheFinding4RegressionSequence passes (epoch 3 created on the old code); the finding's sequence with epoch 2 = [250,300] reverts WindowNotAfterPrevious on the old code and WindowNotContiguous(101) on the new (test_finding4Variant_oldFails_newRefusesNarrowedStart).

     (b) RESOLUTION.md line 5 says test_windowCannotEndInTheFuture 'fails on old code with Panic 0x11'; on the old code propose(.., 1, type(uint64).max) is ACCEPTED, so the first expectRevert fails with 'call did not revert as expected', and the Panic appears only on the NEXT propose (test_oldCode_acceptsMaxToBlock_panicOnlyOnNextPropose).

     The test file itself does not compile against 5f40fa0 (three-argument constructor, nextFromBlock, retire, new errors), so neither claim can have been checked with the file in the tree. (c) Builder fixes 6, 7 and 10 are marked 'manual' with no fixture test, so the skip/refuse classification can regress unnoticed; and every pilot test lives in test/fork, so forge test offline exercises none of the pilot (a mock vault/adapter pattern, as in the scratch test, works offline).

     Four specialists reported parts of this; merged.

     Fix: make epoch 2 in the test start at 250 and expect WindowNotContiguous(101); extend test_windowCannotEndInTheFuture with 'a later propose still succeeds'; correct RESOLUTION; add an offline unit test and a fixture-driven test for the builder's classification.

     New in 548b006: nextFromBlock is seeded from a constructor argument with no check. propose() needs toBlock >= fromBlock == nextFromBlock and toBlock < block.number, so firstFromBlock above the head only waits for the chain, but firstFromBlock = type(uint64).max makes every propose revert (InvalidRoot when toBlock < fromBlock, WindowInFuture when toBlock == max) and there is no governor setter for nextFromBlock.

     pilot/README.md lines 47-49 say every definite exclusion is 'listed in skipped' and name 'not an oracle request' first. The code continues before skip(), so a Completed whose Requested action is not oracle.request@ appears neither in the stage-1 count nor in tally.json's skipped list.

     A reviewer comparing the Intake's Completed count with the tally's candidate + skipped counts (as round one did: 117 Completed vs 103 oracle requests) cannot account for the difference from the published files. Also note the order: a non-oracle Completed whose Requested is older than LOOKBACK refuses the run (line 168 runs before line 169), which is a false refusal the operator can only clear by raising LOOKBACK. Three specialists reported it; merged.

     Fix: skip('not an oracle request') instead of continue, and apply the action filter before the lookback refusal.

Plane-written-data robustness note; every oracle id in the dry-run window is distinct.

     Epoch 0: shares 0.75e18 each; epoch 1: seen is empty, shares 0.75e18 each again.
