• 1.lowThe hourly reference (24h trend and P&L bands) moves one second after a pump placed at the end of an hour, not after an hour of holding as README and THREAT-MODEL section 3 statesrc/CabalGate.sol:282

          else if (latest > ago * 102 / 100) score += 9;

  Merged from audit_math (info) and audit_economics (medium): one mechanism. PleaHook._checkpoint (src/PleaHook.sol:1009-1019) writes, once per hour, the price the hour's FIRST trade found, i.e. the price the previous hour's LAST trade left. CabalGate._factScoreAt reads that newest checkpoint as latest for both the 24h-trend band (line 282: up 9 / flat 5 / down 0) and the P&L band (line 273).

  So a buy in the last second of hour H (which sets no checkpoint of its own once any trade already happened in H) followed by any dust trade in the first second of hour H+1 makes the pumped spot the reference for every plea scored in H+1, including the pumper's own plea in the same transaction as the dust trade. Nothing is held for an hour.

  README 'The fact score' (line 111: 'a pump still has to be held through the hour before') and THREAT-MODEL section 3 ('a pump must be held through the previous hour to move the fact score') state a stronger guarantee than the code gives.

  Severity: Low, not the specialist's Medium.

  No agreed number changes and invariant 3 holds as written (hourly checkpoints, the price an hour's first trade found, never spot); the effect is bounded to the fact score (at most +9 trend points, i.e. a need 4-9 lower for everyone pleading that hour, and a P&L band shift for sellers near the loss boundary), the panel still scores the plea, no pot or sale is touched, and the pump costs the 2% fee on a buy of about 1% of pool depth plus PLEA that can only leave through the gate (max 50% / 2.5M per plea).

  The symmetric direction (an approved seller timing a legitimate sale at HH:59:59, then a dust buy at HH+1:00:00, lowering every other pleader's trend to 'down') follows from the same code but was not separately reproduced here.

  Fix: either reword README line 111 and THREAT-MODEL section 3 to 'the next hour's checkpoint is the price the previous hour's last trade left, so a pump must only be the last trade before the boundary', or, if an hour of holding is wanted, change the checkpoint rule (e.g. record the price the hour's first trade found only when it agrees within tolerance with the price that hour's own first trade found an hour earlier, or use the older of the two newest hourly checkpoints).

  The second option is a contract change outside the agreed numbers and needs the owner's decision.

  Fixture (test/utils/Fixture.sol, Sepolia settings, 5,700 IMD cap, 91 minutes after seed). alice buys 20 IMD, bob buys 2,000 IMD (alice at a deep gain so her P&L band is stable), skip 1 hour, carol buys 1 IMD (checkpoint of the post-bob price), skip 24 hours, keepAlive(alice). Warp to 2 seconds before the next hour boundary: carol buys 1 IMD (hour H's checkpoint = the quiet price; latestPrice <= price24hAgo * 1.02: flat). gate.factScore(alice, balanceOf(alice)/10) == 26 (share 16 + hold 2 + gain 3 + flat 5). At HH:59:59 carol buys 250 IMD: hook.latestPrice() is unchanged (the pump sets no checkpoint). Warp to HH+1:00:00, carol buys 1 IMD: hook.latestPrice() is now the pumped price (> 1.02 x price24hAgo) and gate.factScore(alice, balanceOf(alice)/10) == 30 (trend 9). Expected per README line 111 / THREAT-MODEL section 3: 26, unchanged, because the pump was held one second and not through an hour. Actual: 30.

• 2.infoEvery fresh buyer scores 'at a loss' (13) in a flat market, because the basis is gross of fees and the checkpoint is the pre-trade pricesrc/CabalGate.sol:273

              if (value < spent) {

  From audit_economics (info), reproduced. PleaHook._updateBasis (src/PleaHook.sol:690-698) adds grossImd, what the buyer paid including the 2.0% IMD fee, to imdSpent, and the PLEA received is net of the 0.25% burn and the buyer's own price impact.

  CabalGate compares heldPlea x latestPrice (an hourly checkpoint, the price a trade FOUND) with that gross spend, so in a market that has not moved since the buy the value is about 1.5-3% below the spend and the P&L band is 'at a loss' (13) rather than 'gain <= 50%' (8) until the checkpoint rises past the fee margin.

  The README's calibration sentence ('A fresh buyer selling 15% at a loss needs 37', line 58) reads as one scenario but is the default for every fresh buyer, and the band flips on a sub-3% move either way (which is what makes the Low finding above move a seller's P&L band as well). No agreed number changes; the 'at a loss' band is wider than its name suggests.

  Fix: document it in README 'The fact score' (loss means a loss on the gross spend, fees included), or, as a design change for the owner, compare value with the spend net of the fee.

• 3.infoInvariant 4's 'for the exact rebuilt question' rests on the Intake's pairing, not on an on-chain check: the gate never compares a.questionHash with its own questionsrc/CabalGate.sol:516

          _verifyAttestation(a, signature);
          _consume(a.requestId);

  Documentation precision for THREAT-MODEL invariant 4 ('A verdict is accepted only from the oracle signer, for the exact rebuilt question of the pending plea'). onOracleResult binds the answer to the plea through pleaOfIntake[intakeId] (the Intake's id of the request the gate itself paid for) and the signature over the gate's domain; a.questionHash is signed but never compared with the question the gate built, and the Tribunal's onOracleResult does the same.

  With a relative window ({"hours":1}) the hash cannot be computed on chain (the oracle-consumer reference says so and says the pairing of an answer to the intake request is the writer's), so this is the protocol's trust assumption on the Intake and its writer (THREAT-MODEL section 1 lists the Intake as a trusted contract), not a bypass: no outsider can present an answer for an intakeId the gate created, and a stranger's own request lands on UnknownRequest.

  Reported so that the invariant's wording matches what the code enforces: 'for the request id the gate paid for, as paired by the Intake'. No code change is proposed; if the owner wants the on-chain binding, the body would have to use an absolute block window and store the computed questionHash per plea, which costs gate bytecode (83 bytes of headroom).

  whole finding

  Every verdict test in the repository already shows it: test/utils/Fixture.sol attestation() signs questionHash = keccak256("question") for every plea and every objection, and CabalGate.onOracleResult / Tribunal.onOracleResult accept it (e.g. test/Gate.t.sol, 29 passing tests at this commit). Expected by the invariant's wording: an attestation whose questionHash is not keccak-256 of the gate's canonical question document is refused; actual: accepted, because only the Intake's intakeId and the signer are checked.

   The review is complete. The findings file holds one Info and no defects above it.

   Outcome. Round 2, area A1 (CabalGate, Tribunal, Seasons, OracleAttestation, IPleaParts) is clean at the math, boundary and numerical level. I found no Critical, High, Medium or Low. The one Info is a wording mismatch, not a code defect, and is in .imd-findings.json with its concrete reproduction.

   What I checked, by THREAT-MODEL invariant.

   • Invariants 2 and 3: every agreed number in the three contracts matches section 2 (fees, windows, cooldown, 1% / 50% / 2.5M bounds, the 16/9/3, 7/4/2, 13/8/3, 9/5/0 table, PASS_MARK 71, panel 30, quorum 17, score 0 to 45). The share-band division, the lesser-share rule for appeals, the CannotPass bound, the P&L and trend comparisons and the covered guard behave as written. The appeal's 1% floor against the lesser balance is as the code comment states.
   • Invariant 4 and 6: the callback accepts only the Intake, an unsettled intake id, an unexpired pending plea while the Cabal lives, a verified signature, a consumed oracle request id and a 0 to 45 uint256; the failure path only expires. cabalAlive is computed and a late answer cannot revive it. Expiry and lapse boundaries use the same comparison on both sides.
   • Invariant 1 and 5: the sale pulls exactly p.amount once, inside the window, with a partial-fill revert; the Letterbox-only paths check the flag and the registered Letterbox; PLEA's _update admits only the gate and hook as payers into the PoolManager and only the gate as a puller.
   • Invariants 7 to 10: shareBps sums to 10,000 and falls from 450 to 350 (asserted in a scratch test); best-three replacement and tie keys, top-25 insertion, accountedPot conservation across checkpoint, close, objection stakes and flush, the bonus burn, owner exclusion at record and at close, and the fail-open reads. The fail-open staticcalls cannot be selectively gas-starved because the continuation needs far more than 1/63 of what the callee needs.
   • Invariants 11 to 13: window and expiry comparisons, the two-ruling cap and same-objector rule, pending-slot clearing on ruling and void, stake leaving once via settled, UnfundedStake always satisfied after the Tribunal's own transfer, and the 40-minute maximum hold inside the 60-minute grace.
   • Round-1 fixes for this area (R1-A1-1 to R1-A1-3) are documentation only and match the code.

   The Info. README line 111 says a pump "has to be held through the hour before". The reference is the price the previous hour's last trade left, so a buy one second before an hour boundary plus a dust trade one block later moves both the trend and every seller's P&L band. The probe showed alice's fact score going from 40 to 30 twelve seconds after a pump. Behaviour matches the design intent of "no trade sets its own hour's reference"; only the wording overstates the holding time.

   Test runs. Gate, Seasons, SeatMultiplier, SeasonRanking and the four Tribunal suites pass (141 tests). The invariant, adversarial and fork suites were not run in this session's budget. Scratch probes live under test/scratch/ and are not part of the submission.

   • infoHourly-checkpoint trend and P&L reference moves 12 seconds after a pump placed at the end of an hour (documentation precision, behaviour as designed)src/CabalGate.sol:282

     README section 'fact score' (line 111) and THREAT-MODEL section 3 say 'a pump still has to be held through the hour before'. In the code the reference latest is PleaHook.latestPrice(), the price the first trade of the newest checkpointed hour found, i.e. the price the previous hour's LAST trade left.

     A buy mined in the final seconds of hour H followed by any dust trade in the first block of hour H+1 (12 seconds later) makes the pumped price the reference for every plea scored in hour H+1: the 24h-trend band and the P&L band of every seller move at once. Nothing need be held for an hour; the pump need only be the last trade before the boundary, and while the Cabal lives nobody but an approved seller can trade it back down before the boundary.

     The economics are weak (the pumper keeps PLEA it cannot sell, gains at most +4 trend points and worsens its own P&L band), so this does not break invariant 3 (checkpoints, never spot, are used) and is reported only so the written claim matches the code.

     Suggested fix: reword README line 111 / THREAT-MODEL section 3 to 'the price the previous hour's last trade left', or, if an hour of holding is wanted, checkpoint the price found by the first trade of the hour only when that hour's previous checkpoint is at least one hour old (a contract change outside the agreed numbers).

     Fixture (test/utils/Fixture.sol), default mainnet-like timings. alice buys 50 IMD of PLEA; skip 25 hours; bob buys 1 IMD (checkpoint of the quiet price). gate.factScore(alice, balance/50) = 40 (share 16 + hold 2 + at-a-loss 13 + trend up 9; latestPrice 462796487183101408589196, price24hAgo 453250947750297829343545).

     Warp to one second before the next hour boundary; carol buys 1,500 IMD (pump). factScore(alice) is still 40 and latestPrice unchanged (the pump's own hour keeps its pre-pump reference, as documented). skip(12) across the boundary; carol buys 1 IMD. latestPrice is now 795668111329120571510100 and factScore(alice) = 30: alice's P&L band moved from 'at a loss 13' to 'gain <=200%: 3' twelve seconds after the pump, with no hour of holding.

     Expected per the written design: an hour of holding before the reference moves; actual: one block across the boundary.

3. Audit permissionsAgent #1575found nothing

   The review of round 2, area A1 is complete. The findings file holds an empty list: I found no defect with a concrete failing path in the gate, the Tribunal, Seasons or the attestation library at this commit.

   What I checked, against THREAT-MODEL section 2

   • Invariants 1 to 6 (gate and verdict). Every constant matches the agreed numbers, including the run-7 fact table and PASS_MARK 71. The callback binds by the gate's own intake id, refuses a non-pending, expired or post-death plea, consumes the oracle UUID once, and deletes the id mapping so a second answer or a failure after an approval is refused. A failure clears only its own pending plea and moves no value. The sale pulls exactly the approved amount inside the 7-minute window, once, and PLEA's transfer rule only lets the gate pull it. The fee sale and executeSellFor are Letterbox-only with the auto-sell flag enforced. The appeal window closes at the exact second the denial cooldown ends, so no double sale is possible at the boundary.
   • Invariants 7 to 10 (seasons). The best-three replacement and tie keys never make an entry worse, so the upward-only insertion is sound. The share table sums to 10,000. Pot accounting keeps accountedPot at or below real assets on every path, so UnfundedStake cannot trigger falsely and prizes never exceed the pot. The owner exclusion is applied at record and at close. Every fail-open read (Tribunal, launcher, hook owner, seat NFT) returns "no hold, no exclusion, no multiplier" on failure.
   • Invariants 11 to 13 (Objection!). The two-ruling cap, the different-objector rule, the pending slot, and sustain rule newScore + 2 < need match. Every stake leaves exactly once, through the settled flag. The window plus pending expiry is 40 minutes, inside the 60-minute close grace, so a held plea can never be dropped by a legitimate close.
   • The seat multiplier. Rounding and bounds hold: 45 becomes 54, three pleas 162 in a uint16.

   Empirical probes I ran (all passed, scratch files removed)

   • Worst-case callback gas with 280-byte quote-heavy texts on an appeal and two objections: the gate used at most 86k and the Tribunal 97k of the 200k stipend.
   • A rival calling record under every gas limit from 60k to 400k could not starve the seat read while still completing the record. The seat holder always got the multiplier or the call reverted.
   • An overruled stake settled after the death and the final flush lands in rollover and the next flushToWall sends it to the wall. No stuck funds.
   • The area's regression suites named in FINDINGS.md, 175 tests across Gate, Tribunal, Seasons, SeasonFunds, SeasonRanking, SeatMultiplier, TribunalSeasons, TribunalStanding, TribunalOracleBoundary, OracleReplay, GasPass and AuditRound1, all pass. Every R1-A1 fix is correct and complete.

   One trust note, not a finding. The gate and the Tribunal do not check questionHash. They rely on the Intake's writer pairing each signed answer with the right request id, which the oracle reference says is the writer's job and the threat model lists as trusted. If that trust assumption ever changes, both callbacks would need a question pin.

   Coverage limits. I did not run the fork or invariant suites, and hook internals such as the hourly checkpoint ring were read only as far as the fact score consumes them, since they belong to area A3.

4. Audit flowAgent #507found nothing

   The review of area A1 found no reproducible defect at this commit. The findings file .imd-findings.json holds an empty list, which is a deliberate clean result, not an omission.

   What I checked, against THREAT-MODEL section 2

   • Invariants 1, 4, 6 (gate and verdict). The callback binds an answer to a pending plea only through the Intake's own request id, consumes the oracle request id once, deletes the intake mapping, and refuses anything after the 20-minute expiry or after the death. The failure function clears only a pending plea of ours and moves nothing. The sale checks the window, the exact amount, and single execution, and PLEA's transfer rule lets the gate pull only from its own transferFrom. The hook refuses any sell whose swap sender is not the gate. The Letterbox-only entry points check the registered Letterbox and the flag range.
   • Invariants 2, 3, 5 (amount, fact score, cooldowns). The run-7 table in _factScoreAt matches the agreed numbers and sums to 45, the need floor is 26, and CannotPass fires before any fee is pulled. The appeal's lesser-share rule, the lesser-balance amount check, the lapse cooldown dated from the verdict and the retry of an unanswered appeal all behave as documented.
   • Invariants 11 to 13 (Objection!). The two-ruling cap, the different-wallet rule, the pending slot freed only by a stale or failed request, the sustain rule, and stake flows were traced and exercised. A scratch walk through void, overrule and sustain left the Tribunal's balance exactly where it started. The hold's 40-minute bound sits inside the 60-minute grace at every edge, including a stale void at the window's last second.
   • Invariants 7 to 10 (Seasons). Record once, held and sustained refusals, the best-three replacement with its tie keys, the top-25 insertion, shareBps summing to 10,000, accountedPot never exceeding the pot, rollover and the bonus burn, the owner exclusion at record and at close, and every fail-open read. The seat multiplier stays within the uint8 and uint16 bounds.

   Experiments run

   • The area's unit suites all pass under the default profile.
   • A gas sweep of a rival's record call from 30k to 400k gas never produced a record that dropped a seat holder's multiplier. The 63/64 rule makes the seat read fail only when the rest of the record cannot complete.
   • A pending plea at the death cannot be revived by a late verdict and expires cleanly.
   • Callback gas is well under the Intake's stipend on both consumers.

   Not run

   • The invariant, adversarial and fork suites need the full profile, which compiles the whole tree in one via-IR job beyond this task's time budget. The fork rehearsal is what validates the live Intake's requests() layout that staleness relies on. Those suites are unchanged since round 1, where they passed.

   One observation, not a finding. The P&L band reads the trader's real cost basis against the hourly checkpoint price. A holder deep in profit can buy more at a premium to push their basis above the checkpoint and pick up the at-a-loss points, but the premium they pay is of the same order as the gain they erase, and the plea stays capped at half the balance. The contract computes exactly what the spec says, so I did not report it.

   Review of round 2, area A1 is complete. The findings file is written at the repository root.

   Outcome. No Critical or High in the gate, the Tribunal, Seasons or the attestation code. One Medium and one Info, both in the fact score. Every regression suite for this area passes.

   What I checked, against THREAT-MODEL section 2.

   • Invariants 1, 4, 5, 6 (gate and verdict): the callback binds to the gate's own intake id and the oracle UUID once, refuses a wrong sender, an unknown or settled id, a late answer and a dead Cabal. The failure function only expires a Pending plea of its own. The sale is one swap of the exact amount inside 7 minutes, status Executed blocks a repeat, and the Letterbox is the only caller of submitFor, appealFor and executeSellFor. The hook refuses sells from any sender but the gate and exact-output buys, so ERC-6909 claims give no second route. The appeal path cannot be used twice, nor after the 4-hour window.
   • Invariants 2, 3: all agreed numbers in the three contracts match, including the run-7 table, PASS_MARK 71 and the shareBps table, which sums to 10,000.
   • Invariants 11, 12, 13 (Objection!): the two-ruling cap, the different-objector rule, the single pending slot, stake conservation across sustained, overruled, void and expired, and the 40-minute hold inside the 60-minute grace all hold. UnfundedStake is unreachable because accountedPot never exceeds the pot.
   • Invariants 7, 8, 9, 10 (Seasons): record once, held and sustained refusals, best-three replacement and tie keys, top-25 insertion, pot versus accountedPot, rollover, bonus burn, owner exclusion at record and close. The fail-open reads cannot be starved by the caller's gas because of the 63/64 rule, and the seat multiplier stays within uint8 and uint16.

   Findings.

   • Medium, src/CabalGate.sol:282. The 24h trend fact can be moved by a pump held for one second across an hour boundary. A buy at HH:59:59 sets no checkpoint. Any dust trade at HH+1:00:00 writes the pumped price as the new hour's checkpoint. The plea can go in the same transaction. The threat model says a pump must be held through the previous hour. The test at test/scratch/TrendBoundary.t.sol fails on this code with "30 != 26" and is attached as the proof. It builds on the repository's Fixture, so it is not self-contained in the strict sense.
   • Info, src/CabalGate.sol:273. Every fresh buyer is "at a loss" by construction, since the basis is gross of fees and the checkpoint is the pre-trade price. A 20 IMD buy in a flat market scores 13 loss points with a value of 19.8 IMD against 20 spent.

   Not done. I did not attempt the fork or invariant suites under the full profile. I did not build a self-contained proof without the Fixture, which would need the whole launch replay.

   • mediumThe 24h trend fact is moved by a pump held for one second across an hour boundary, not 'through the previous hour'src/CabalGate.sol:282

     THREAT-MODEL section 3 ('One trade per hour sets no reference ... a pump must be held through the previous hour to move the fact score') and README 'The fact score' state the reason the fact score reads the hook's hourly checkpoints instead of spot. The guarantee the code gives is weaker. PleaHook._checkpoint (src/PleaHook.sol:1009-1019) writes, once per hour, the price the hour's FIRST trade found.

     CabalGate._factScoreAt reads latestPrice() (that newest checkpoint) against price24hAgo() and awards the 'up' trend (9 instead of flat 5 or down 0) when latest > ago * 1.02. So a buy in the last second of hour H (which sets no checkpoint of its own when any trade already happened in H) followed by any dust trade in the first second of hour H+1 makes the pumped spot H+1's checkpoint.

     The pump is held for one second, and the dust trade and the plea can be the same transaction (the fact score is computed at submit time), so the pumper, and every other seller pleading that hour, is scored on the 'up' trend. On a 'down' day this converts 0 trend points into 9: the need falls by 9 of 45.

     The cost is the 2% fee on a buy of roughly 1% of pool depth plus holding the bought PLEA (which can only leave through the gate), and with the seat multiplier and best-three scoring the 9 points of need are worth prize rank. The same one-second mechanism also lowers the P&L fact for sellers near the fee-induced loss boundary (see the Info finding).

     This does not change an agreed number; it is the documented mechanism (held through the previous hour) not being what the code enforces.

     Fixing it needs a checkpoint that cannot be set by the last trade of the previous hour, for example recording the price the previous hour ENDED with only if it was also the price found by the previous hour's first trade within tolerance (i.e. both ends of hour H agree), or a time-weighted average over the hour, or using the older of the two most recent hourly checkpoints; or, if the owner accepts the one-second hold, correcting THREAT-MODEL section 3 and README so auditors and holders do not rely on the hour-long hold.

     whole finding

     Fixture (Sepolia settings, 5,700 IMD cap). alice buys 20 IMD, bob buys 2,000 IMD (alice at a deep gain so her P&L band is stable); an hour later carol's dust buy checkpoints the post-bob price; 24 h later keepAlive.

     At HH:59:58 carol's dust buy sets hour H's checkpoint = the quiet price (latestBefore 918e21 vs ago 918e21: flat; alice's factScore for 10% of her balance = 26 = share 16 + hold 2 + gain 3 + flat 5).

     At HH:59:59 carol buys 250 IMD (hook.latestPrice() unchanged: the pump sets no checkpoint).

     At HH+1:00:00 carol's 1 IMD dust buy writes the new hour's checkpoint = the pumped price (987e21 > 1.02 x ago). alice's factScore is now 30 (trend 9).

     Expected per THREAT-MODEL section 3: unchanged (26) because the pump was not held through an hour.

     Actual: 30; the pumper's own plea in that same transaction gets the same 9. test/scratch/TrendBoundary.t.sol fails on this code with '30 != 26'.

     The test extends the repository's own launch replay test/utils/Fixture.sol (PoolManager, mocks, hook salt mining, seed), so run it in place: forge test --match-path test/scratch/TrendBoundary.t.sol.

   • infoEvery buyer is 'at a loss' (13 points) until the checkpoint price rises about 2.3% plus slippage above their fill, because the basis is gross of fees and the checkpoint is the pre-trade pricesrc/CabalGate.sol:273

     PleaHook._updateBasis adds grossImd 'what the trader paid ... including fees' (src/PleaHook.sol:688-697) to imdSpent, while the value CabalGate compares it with uses the hourly checkpoint, which is the price the hour's first trade FOUND (pre-trade).

     A buyer in a flat market therefore holds PLEA 'worth' less than spent by the 2.0% IMD fee, the 0.25% PLEA burn and their own price impact, and scores the 'at a loss' 13 instead of 'gain <= 50%' 8 until the checkpoint rises past that margin.

     The README's calibration ('A fresh buyer selling 15% at a loss needs 37') reads as one scenario, but it is the default for every fresh buyer: in the Fixture a 20 IMD buy scores 16 + 2 + 13 + 5 = 36 after a day with no price move (value 19.8 IMD vs spent 20).

     The flip side is that the P&L band is decided by a sub-3% move either way, so a one-second boundary pump (the Medium finding) of +4% moves such a seller from 13 to 8 while giving them trend 9, and a tiny drift down gives 13. No agreed number changes; the table's 'at a loss' band is simply wider than its name suggests.

     If the owner wants 'loss' to mean a loss on the market price, compare value with spent net of the fee (spent * 9800 / 10000) or require value < spent by more than the fee margin; otherwise document it in README 'The fact score'.

     whole finding

     Fixture: buy(alice, 20e18); skip(1 days); keep the Cabal alive; gate.factScore(alice, balance/10) == 36 and hook.basisOf(alice) == (spent 20e18, held 3.41e24, ...). value = 3.41e24 * latestPrice / 2^96 = 19.8e18 < 20e18 although the pool price has not fallen since the buy (the only trades were the buy itself). Expected by the README's reading of 'at a loss': 8 (no loss on price); actual: 13.

6. Audit judgeAgent #1355found 1 low, 2 info

   The review is complete and .imd-findings.json holds the result: one Low and two Infos, no Critical, High or Medium.

   What I kept, merged, and dropped

   • Low, merged (audit_math info + audit_economics medium, one mechanism): the hook's hourly checkpoint is the price the hour's first trade found, so a buy in the last second of hour H plus any dust trade in the first second of H+1 makes the pumped price the reference for every plea scored that hour. I reran the specialist's proof in test/scratch and it fails as stated, fact score 26 to 30. I downgraded it from Medium to Low: no agreed number changes, invariant 3 holds as written, the effect is bounded to at most 9 fact points shared by everyone pleading that hour, no pot or sale is touched, and the pump costs the 2% fee plus PLEA that can only leave through the gate. README line 111 and THREAT-MODEL section 3 claim an hour of holding the code does not enforce. No proof is attached, since the likely fix is documentation, which no test can be held to. The test source is in the reproduction field.
   • Info, kept (audit_economics): a fresh buyer in a flat market is "at a loss" by default because the basis is gross of fees and the checkpoint is the pre-trade price. Reproduced: value 19.69 IMD against 20 spent, fact score 36.
   • Info, mine: invariant 4's "for the exact rebuilt question" rests on the Intake's pairing of answer to request id, not on an on-chain questionHash check. The fixture signs a constant questionHash for every verdict and the gate accepts it. This is the protocol's documented trust assumption, reported for wording precision only.
   • audit_permissions and audit_flow reported nothing. I found nothing in their areas either.

   What I checked and found sound

   • Invariants 3 to 13 by code reading of CabalGate, Tribunal, Seasons and OracleAttestation: verdict binding, replay, expiry and dead-man handling, the sale window and Letterbox-only fee sale, appeal lesser-share band, the two-ruling cap and pending slot, stake conservation, the best-three tie keys, the top-25 insertion, shareBps sum of 10,000, pot versus accountedPot, the owner exclusion, every fail-open read, and the uint8 and uint16 bounds of the seat multiplier.
   • A rival gas-starving record to strip a seated seller's multiplier is infeasible: EIP-150 leaves only 1/64 of the gas after a failed seat read, far less than the record's own writes need. This assumes the mainnet seat NFT's balanceOf stays well under 100k gas, which I could not verify offline.
   • A new probe confirmed invariant 13: a verdict in a season's last second with an unanswered last-second objection still records at the close, and the stake comes back exactly once.
   • The area's regression suites pass at this commit: 122 tests across Gate, Seasons, Tribunal, SeatMultiplier, TribunalSeasons, SeasonRanking, OracleReplay and GateAdversarial.

   One probe of mine was inconclusive and is not reported: the sale-across-the-boundary direction of the trend issue. My test instead exposed the 25-slot ring falling back to a 27-hour-old checkpoint for the 24h reference, which is consistent with the view's "at least 24 hours ago" documentation.

   • lowThe hourly reference (24h trend and P&L bands) moves one second after a pump placed at the end of an hour, not after an hour of holding as README and THREAT-MODEL section 3 statesrc/CabalGate.sol:282

     Merged from audit_math (info) and audit_economics (medium): one mechanism. PleaHook._checkpoint (src/PleaHook.sol:1009-1019) writes, once per hour, the price the hour's FIRST trade found, i.e. the price the previous hour's LAST trade left. CabalGate._factScoreAt reads that newest checkpoint as latest for both the 24h-trend band (line 282: up 9 / flat 5 / down 0) and the P&L band (line 273).

     So a buy in the last second of hour H (which sets no checkpoint of its own once any trade already happened in H) followed by any dust trade in the first second of hour H+1 makes the pumped spot the reference for every plea scored in H+1, including the pumper's own plea in the same transaction as the dust trade. Nothing is held for an hour.

     README 'The fact score' (line 111: 'a pump still has to be held through the hour before') and THREAT-MODEL section 3 ('a pump must be held through the previous hour to move the fact score') state a stronger guarantee than the code gives.

     Severity: Low, not the specialist's Medium.

     No agreed number changes and invariant 3 holds as written (hourly checkpoints, the price an hour's first trade found, never spot); the effect is bounded to the fact score (at most +9 trend points, i.e. a need 4-9 lower for everyone pleading that hour, and a P&L band shift for sellers near the loss boundary), the panel still scores the plea, no pot or sale is touched, and the pump costs the 2% fee on a buy of about 1% of pool depth plus PLEA that can only leave through the gate (max 50% / 2.5M per plea).

     The symmetric direction (an approved seller timing a legitimate sale at HH:59:59, then a dust buy at HH+1:00:00, lowering every other pleader's trend to 'down') follows from the same code but was not separately reproduced here.

     Fix: either reword README line 111 and THREAT-MODEL section 3 to 'the next hour's checkpoint is the price the previous hour's last trade left, so a pump must only be the last trade before the boundary', or, if an hour of holding is wanted, change the checkpoint rule (e.g. record the price the hour's first trade found only when it agrees within tolerance with the price that hour's own first trade found an hour earlier, or use the older of the two newest hourly checkpoints).

     The second option is a contract change outside the agreed numbers and needs the owner's decision.

     whole finding

     Fixture (test/utils/Fixture.sol, Sepolia settings, 5,700 IMD cap, 91 minutes after seed). alice buys 20 IMD, bob buys 2,000 IMD (alice at a deep gain so her P&L band is stable), skip 1 hour, carol buys 1 IMD (checkpoint of the post-bob price), skip 24 hours, keepAlive(alice). Warp to 2 seconds before the next hour boundary: carol buys 1 IMD (hour H's checkpoint = the quiet price; latestPrice <= price24hAgo * 1.02: flat). gate.factScore(alice, balanceOf(alice)/10) == 26 (share 16 + hold 2 + gain 3 + flat 5). At HH:59:59 carol buys 250 IMD: hook.latestPrice() is unchanged (the pump sets no checkpoint). Warp to HH+1:00:00, carol buys 1 IMD: hook.latestPrice() is now the pumped price (> 1.02 x price24hAgo) and gate.factScore(alice, balanceOf(alice)/10) == 30 (trend 9). Expected per README line 111 / THREAT-MODEL section 3: 26, unchanged, because the pump was held one second and not through an hour. Actual: 30.

     CabalGate compares heldPlea x latestPrice (an hourly checkpoint, the price a trade FOUND) with that gross spend, so in a market that has not moved since the buy the value is about 1.5-3% below the spend and the P&L band is 'at a loss' (13) rather than 'gain <= 50%' (8) until the checkpoint rises past the fee margin.

   • infoInvariant 4's 'for the exact rebuilt question' rests on the Intake's pairing, not on an on-chain check: the gate never compares a.questionHash with its own questionsrc/CabalGate.sol:516

     Documentation precision for THREAT-MODEL invariant 4 ('A verdict is accepted only from the oracle signer, for the exact rebuilt question of the pending plea'). onOracleResult binds the answer to the plea through pleaOfIntake[intakeId] (the Intake's id of the request the gate itself paid for) and the signature over the gate's domain; a.questionHash is signed but never compared with the question the gate built, and the Tribunal's onOracleResult does the same.

     With a relative window ({"hours":1}) the hash cannot be computed on chain (the oracle-consumer reference says so and says the pairing of an answer to the intake request is the writer's), so this is the protocol's trust assumption on the Intake and its writer (THREAT-MODEL section 1 lists the Intake as a trusted contract), not a bypass: no outsider can present an answer for an intakeId the gate created, and a stranger's own request lands on UnknownRequest.

     Reported so that the invariant's wording matches what the code enforces: 'for the request id the gate paid for, as paired by the Intake'. No code change is proposed; if the owner wants the on-chain binding, the body would have to use an absolute block window and store the computed questionHash per plea, which costs gate bytecode (83 bytes of headroom).

     whole finding

     Every verdict test in the repository already shows it: test/utils/Fixture.sol attestation() signs questionHash = keccak256("question") for every plea and every objection, and CabalGate.onOracleResult / Tribunal.onOracleResult accept it (e.g. test/Gate.t.sol, 29 passing tests at this commit). Expected by the invariant's wording: an attestation whose questionHash is not keccak-256 of the gate's canonical question document is refused; actual: accepted, because only the Intake's intakeId and the signer are checked.
