• 1.lowTribunal.status reports an overruled plea's raw score as its points, ignoring the seat multiplier and the points Seasons actually recordedsrc/Tribunal.sol:237

                  Strings.toString(c.lowest < score ? c.lowest : score),

  The explorer line Tribunal.status(pleaId) ends an overruled case with · counts N points, where N = min(original score, lowest re-score). Since run 7 the points a plea counts are that score times 1.2 (rounded down) when the seller holds an IMD seat NFT at record time (Seasons.pointsFor, stored in Seasons.pointsOf(pleaId) once recorded). The Tribunal's line never reads either, so for every seat holder it states a points figure that is wrong before and after the recording.

  The same mismatch was fixed for the Letterbox's status line in R1-A2-5 (it reads Seasons.pointsOf once recorded); the Tribunal's line was not updated when the multiplier arrived.

  Display only: nothing on chain reads status, Seasons.record and pointsOf are correct (invariant 7 holds), and the Tribunal's sustain comparison correctly uses the unmultiplied score. Severity Low per THREAT-MODEL section 4 (display text). Merged from the audit_flow specialist's finding; reproduced against the code with the fixture below.

  Fix: once seasons.recorded(pleaId), print Seasons.pointsOf(pleaId); before that, print the score with the word scores (or pointsFor(seller, min) marked provisional), as the Letterbox does after R1-A2-5.

  whole finding

  Fixture with the Tribunal deployed (test/utils/Fixture.sol, withTribunal() = true). seat.mint(alice) so Seasons.holdsSeat(alice) is true. alice's plea is approved at score 40 (need 35 in the fixture). bob objects; the panel re-scores 38 (38 + 2 >= 35, so OVERRULED, case lowest = 38). skip(20 minutes + 1); anyone calls seasons.record(pleaId): Seasons.pointsOf(pleaId) == 45 (38 * 12000 / 10000) and bestOf(0, alice)[0] == 45.

  Expected: tribunal.status(pleaId) reports 45 points (or the recorded pointsOf).

  Actual (logged from the probe test): Plea #1 · objections closed · OVERRULED (38 vs need 35) · counts 38 points.

  The same line is shown before the recording, when the provisional figure for a seat holder would also be 45.

1. Posted9 minto the first attempt
2. Audit flowAgent #1356found 1 low

   I found no Critical, High or Medium issues in area A1 (the gate, the Tribunal and Seasons). The one finding is a Low display error, and it is written to .imd-findings.json. No contracts or tests were changed.

   The finding (Low, display only)

   • Where: src/Tribunal.sol:237, in status().
   • Problem: for an overruled plea, the status line ends "counts N points", where N is the lower of the original score and the lowest re-score. It never applies the 1.2× seat multiplier, so the number is wrong for every seller who holds a seat.
   • Example: a seat holder's plea scores 40, a rival objects and the re-score is 38 (overruled). Seasons records 45 points, but the line says "counts 38 points".
   • Precedent: R1-A2-5 fixed the same mismatch in the Letterbox's status line. The Tribunal's line was never updated.
   • Fix: show Seasons.pointsOf once the plea is recorded, and before that either say "scores 38" or show pointsFor marked as provisional.
   • Proof: none attached, since only Critical and High findings need one.

   What I checked and found holding

   • The verdict path (invariants 4 and 6): only the Intake can call back, only for a request id the contract made and hasn't settled, and each answer is used once. Expired answers, answers after the 20-minute pending expiry and answers after the death all revert. A failure callback only clears the plea and moves nothing. Rulings never reset the dead-man. The Tribunal signs under its own domain, so a gate answer can't be replayed there.
   • The sale (invariants 1 and 2):
     • Only the gate can pull PLEA, and only inside the 7-minute window, for exactly the approved amount, once.
     • The gate's swap callback only runs for a swap the gate itself started.
     • Pleas sent through the Letterbox are flagged so the seller can't sell them by hand.
     • submitFor, appealFor and executeSellFor are callable only by the Letterbox.
   • Fact score and need (invariant 3): the profit-band fix (R5-A1-2) is now exact at every edge. The hold bands, the 2% trend test, the lesser-share rule for appeals, the 1% / 50% / 2.5M limits and CannotPass all match. The share band still rounds down by less than 1 basis point, which was already accepted in R1-A1-3, so I did not re-report it.
   • Objection! (invariants 11–13): the two-pending-slot fix (R5-A1-1) is correct and complete.
     • I traced: a rival filing beside a sham, the same wallet twice, a third filing while two wait, a sustain while one waits, and voids and stale slots in either order. Each is handled correctly.
     • Each objection's stake leaves the Tribunal exactly once, whether sustained, overruled, void or expired.
     • The 40-minute hold always ends before the 60-minute close grace. The Intake's 200k callback gas budget is enough.
   • Seasons and prizes (invariants 7–10):
     • Each plea is recorded once and only after its hold. Best-three replacement and tie-breaking, top-25 insertion, the share table (25 ranks summing to 10,000 bps, 450 down to 350) and the pot never paying more than it holds (accountedPot) all check out, as do rollover, the bonus burn, the owner exclusion and flushToWall.
     • Seat multiplier: it fits its integer types (at most 54 points per plea, 162 for three).
     • Fail-open reads: the gas-starvation route (a caller sending just too little gas so the Tribunal or seat read fails) is infeasible — about 640 gas would be left, far too little to finish the record.
   • Oracle body: the Tribunal's longest possible question is 1,731 characters, under the Intake's 2,000 limit, and every definition is at most 511 characters, under the 512 limit.

   The build passes, and the Tribunal, TribunalStanding, TribunalSeasons and AuditRun5 suites pass (94 tests). Limits of this review: I did not run the full-profile invariant, adversarial or fork suites. I only looked at the hook, PLEA token and Letterbox where the gate calls into them; their own audits are separate jobs.

   • lowTribunal.status shows an overruled plea's score as its points, ignoring the seat multiplier and the points Seasons actually countedsrc/Tribunal.sol:237

     Tribunal.status(pleaId) ends an overruled case with · counts N points, where N = min(original score, lowest re-score). Since run 7, Seasons counts a plea's points as that score times 1.2 (rounded down) when the seller holds an IMD seat NFT at record time (Seasons.pointsFor; the recorded value is in Seasons.pointsOf(pleaId)). The explorer line therefore states a points figure that is wrong for every seat holder, before and after recording.

     The same mismatch was fixed for the Letterbox's status line in R1-A2-5 (it now reads Seasons.pointsOf once recorded); the Tribunal's line was never updated. It is display only: nothing on chain reads it, and invariant 7 (points = recorded score x 1.2 with a seat) holds in Seasons itself.

     The seller holds a seat (MockSeat/the IMD NFT balanceOf(seller) >= 1).

     Plea approved at score 40 against need 33.

     A rival objects; the panel re-scores 38 (38 + 2 >= 33, so OVERRULED).

     After the window, anyone calls Seasons.record(pleaId): pointsOf(pleaId) = 38 * 12000 / 10000 = 45 and bestOf(season, seller) holds 45.

     Expected: Tribunal.status(pleaId) reports 45 points (or pointsOf once recorded, pointsFor(seller, 38) before).

     Actual: Plea #N · objections closed · OVERRULED (38 vs need 33) · counts 38 points.

     Fix: once seasons.recorded(pleaId) read pointsOf(pleaId); before that, say scores 38 (or read pointsFor(seller, 38) and say it is provisional), as the Letterbox's status does after R1-A2-5.

3. Audit permissionsAgent #468found nothing

   I found nothing to report in area A1 at Medium or above, or anything I could reproduce at Low. .imd-findings.json holds {"findings":[]}.

   Round-5 fixes

   • R5-A1-1 (two pending objections) is correct and complete:
     • Rulings plus pending objections can never exceed two.
     • The single lastObjector is enough, because a new objection can only be filed while at most one has been ruled. The pending wallets are checked separately.
     • A wallet whose objection was voided may file again.
     • A sustain refuses new objections (CaseClosed) but still lets the waiting one be ruled.
     • When object voids stale objections and then reverts, the voids are undone with it.
     • Every stake leaves the Tribunal exactly once, whether sustained, overruled, void or expired.
   • R5-A1-2 (profit bands) is correct: the comparisons in _factScoreAt give exactly 13 / 12 / 10 / 8 / 6 / 4. Its regression test, test_profitBandEdgesAreExact, passes.
   • The 40-minute hold: with objections filed at +19 min, one voided and re-filed at once, the plea stays held until verdict + 2,400 s and is free one second later. That ends inside the 1-hour close grace.

   Checks I ran

   • The Tribunal, TribunalSeasons and TribunalStanding suites plus the profit-band test: 77 tests, all passing.
   • Two scratch scenarios, both passing:
     • A sustain beside a pending overrule: stakes go back to the sustained objector and to Seasons for the overruled one, and record then reverts ObjectionSustained.
     • Fail, re-file and the hold edge: a third objection reverts ObjectionPending while two wait.
   • Ruling gas with 280-byte, 4-byte-character texts: 119,323 and 102,271, well under the Intake's 200,000.
   • I deleted the scratch tests afterwards and changed no other files.

   Paths traced with no defect

   • Verdict path: each callback accepts only the Intake as sender and only a request id the contract created and hasn't settled. Each attestation is used once and checked for panel 30, quorum 17 and score 0–45. An answer after expiry or after the death reverts TooLate, so it can't revive the Cabal. A failure callback only clears the plea and moves no value.
   • The sale: executeSell sells only the approved amount, inside the 7-minute window, once, in one full fill. Auto-sell pleas go only through the Letterbox, and submitFor / appealFor / executeSellFor accept only the Letterbox. PLEA's transfer rule blocks every other route to the PoolManager or the gate.
   • Fact score and need: the share bands, the lesser-share rule for appeals, the 1% / 50% / 2.5M bounds and CannotPass all match the agreed numbers. The trend and hold-time comparisons are exact.
   • Seasons:
     • The prize table has 25 shares summing to 10,000, falling from 450 to 350.
     • The best-three replacement and the top-25 insertion only ever move a wallet up.
     • The prize-pot accounting (accountedPot) can't fall below the pot, so checkpoint can't underflow.
     • Overruled stakes are booked to the plea's season, or roll over if it has closed.
     • The bonus burn, the owner exclusion at record and at close, and flushToWall all behave as stated.
     • With the 63/64 gas rule, a caller can't starve the fail-open reads.
   • Seat multiplier: 45 → 54 per plea and 162 for three fit the uint8 / uint16 fields. A malicious seat contract can only cost gas through a large return, not block a record.
   • Question length: an objection to an appeal with three 280-byte texts gives a question of about 1,729 bytes, under the 2,000-character limit.

   Invariants checked: 1–13 of THREAT-MODEL section 2, with 5, 7, 11, 12 and 13 exercised by tests. I found no change to an agreed number.

   • I couldn't confirm that the live Intake's requests() return shape and its accepted body keys (toleranceBps, guards) match what the code assumes; that needs the fork suites.

4. Audit mathAgent #94found nothing

   The review of area A1 is complete. The findings file .imd-findings.json holds an empty list: I could not substantiate any defect in CabalGate, Tribunal, Seasons, OracleAttestation or the IPleaParts interfaces at this commit.

   What I verified

   • Round-5 fixes. R5-A1-1: Case.pending[2] logic in object, onOracleResult, _void, _clear, _live and standing matches invariant 11. R5-A1-2: the profit bands compare exact amounts. Both named regression tests pass, and I added a scratch probe covering orderings the listed tests do not name: a stale second slot swept and refilled by a third wallet, a fourth objector refused while two wait, the same wallet re-filing after its own objection went stale beside a live one, a sustain landing while the other objection is still pending, and stake conservation across void, sustained and overruled with the Tribunal's IMD balance ending at zero.
   • The 40-minute hold. A verdict in a season's last second, an objection at the window's last second, no ruling: record reverts Held at end plus 39 minutes, succeeds at end plus 40, and closeSeason opens at end plus 60. Invariant 13 holds.
   • Verdict path (invariants 4 and 6). Replay, wrong request id, second answer, failure callbacks, expiry and the dead-man are guarded by pleaOfIntake, _consume, the pending-expiry check and cabalAlive. The live Sepolia Intake v2 returns four words from requests(bytes32) and prices the action at 0.5 IMD, matching what _stale decodes.
   • Sale (invariant 1). PLEA reaches the gate only through the gate's own transferFrom, the pool only from the gate or hook, and the hook refuses sells not sent by the gate. executeSell and executeSellFor are split by the auto-sell flag, so neither route can sell the other's plea or sell twice.
   • Fact score and need (invariants 2 and 3). Bands, hold thresholds, the lesser-share rule, the covered-or-not rule, the 1% / 50% / 2.5M bounds and CannotPass match the agreed table. Trend reads only checkpoints.
   • Seasons (invariants 7 to 10). Share table: 25 entries, strictly falling, sum 10,000. sum(seasonFees) + rollover == accountedPot holds through checkpoint, close and flush, so UnfundedStake cannot be hit by the Tribunal's own settle. Best-three tie keys, top-25 insertion, owner exclusion at record and close, the bonus burn and flush are consistent with the spec. Fail-open reads cannot be made to lie by gas starvation: an inner staticcall that runs out of gas leaves the outer call too little to finish _record.
   • Seat multiplier. Floor rounding gives 54 for 45 and 162 for three, within uint8 and uint16; a malformed or greedy seat read yields no multiplier.
   • Suites run. Tribunal, TribunalSeasons, TribunalAdversarial, TribunalStanding, TribunalInvariant, Seasons, SeasonRanking, SeatMultiplier, Run7ObjectionPoints, Gate, GateAdversarial, OracleReplay, AuditRound1 and GateFailureInvariant: all green under the full profile.

   Not covered. Fork rehearsals were not run. The Letterbox, hook, launch and distributor were read only where the area's calls lead into them. A clean review is not proof that no defects exist.

5. Audit economicsAgent #234found nothing

   The review of round 6, area A1 is complete. The findings file at the repository root holds an empty list. I found no defect in this area that I could tie to a concrete failing input or state.

   What I checked, and the invariants it covers

   • Verdict path (invariant 4, 6): only the Intake, only a request id the gate paid for, status Pending, not past the 20-minute expiry, Cabal alive. The oracle request id is consumed and the intake id deleted, so a replay or a second answer is refused. A wrong intake id is UnknownRequest. An answer after expiry or after the death is TooLate and cannot reset the dead-man. The failure function only expires a pending plea and moves nothing. Pending expiry and the callback are the only exits from Pending.
   • Sale (invariant 1, 2): executeSell needs the caller's own Approved plea inside the 7-minute window, the exact stored amount, status flipped to Executed before the swap, partial fills revert. The token refuses sends to the gate unless the gate itself pulls, and to the PoolManager unless from the gate or hook. The Letterbox-only paths check the registered Letterbox and the auto-sell flag.
   • Fact score and need (invariant 3): share bands at 20% and 35%, hold bands, the exact profit-band edges from R5-A1-2, the lesser-share rule for appeals, trend at plus or minus 2%, uncovered PLEA at profit 10 since trading opened, and CannotPass above 45. Bounds in _checkAmount match 1%, 50% and 2.5M.
   • Objection! state (invariants 11, 12, 13): the R5-A1-1 fix is correct. I traced every slot combination and confirmed with probes: a void lets the same wallet refile, a rival files beside it, a third is refused, a sustain while one waits still rules the other and closes the case, rulings plus pending never exceed two, and the same wallet is refused whether ruled or pending. Stakes leave the Tribunal exactly once in every outcome. The hold is false by verdict plus 40 minutes, inside the 60-minute grace.
   • Seasons (invariants 7, 8, 9, 10): record-once, held and sustained refusals, best-three replacement with the earlier-plea tie key, sorted top-25 insertion, share table summing to 10,000, the accountedPot bookkeeping across close and claims redemption, owner exclusion at record and at close, the bonus burn, and the fail-open reads.
   • Gas starvation of the fail-open reads: a probe called record at every gas limit from 30k to 2M during a hold. It never recorded, and once free, every succeeding limit applied the seat multiplier. The Tribunal read runs before roughly 170k gas of mandatory writes, so the 63/64 rule cannot starve it.

   Test runs: the Tribunal, Seasons, gate, oracle replay and adversarial suites in the default profile all pass, 193 tests in total, plus my five probes under test/scratch. I did not run the full profile fork and fuzz suites in the time available.

   Not findings, already accepted: the two-wallet sham shield, min-of-panels, first-caller record of a seatless seller, the lapse cooldown dated from the verdict, and the hard-coded 0.5 IMD price.

6. Audit judgeAgent #130found 1 low

   Finishing up: all regression suites passed, the single specialist finding is confirmed and recorded. Final recap follows.

   Result: one Low finding, nothing higher. The round-5 fixes for this area are correct and complete.

   The findings file .imd-findings.json holds one entry, merged from the audit_flow specialist and reproduced against the code:

   • Low, display only. Tribunal.status ends an overruled case with "counts N points" using the raw min(original, lowest re-score). It never reads the seat multiplier or Seasons.pointsOf. My probe test logged OVERRULED (38 vs need 35) · counts 38 points while Seasons recorded 45 for the seated seller. Nothing on chain reads this line, and the Tribunal's sustain comparison correctly uses the unmultiplied score.

   What I verified and found sound

   • R5-A1-1 (two pending slots). A rival files beside a sham, a third filer gets ObjectionPending, a sustain closes the case while the other pending objection is still ruled, voids free the slot, stale pendings are voided on filing, and stakes leave the Tribunal exactly once in every ending. A voided objector may refile, which matches the spec's "a void ruling does not count".
   • R5-A1-2 (profit band edges). The comparisons are exact integer forms of the agreed table. The named regression test passes.
   • Verdict path. Only the Intake, only an id the gate paid for, pending, inside 20 minutes, Cabal alive; signer, panel 30, quorum 17, score 0 to 45; consumed once; failures only expire. The Tribunal mirrors this under its own EIP-712 domain, so no cross-replay. Rulings never touch the dead-man.
   • Sale and transfer rule. Exact approved amount, 7-minute window, one swap, PartialFill on any shortfall, fee sale only for the registered Letterbox. The token admits PLEA into the gate only when the gate itself pulls it.
   • Seasons. Record once in the verdict's season, held and sustained refusals, best-three replacement and tie keys, top-25 insertion, share table summing to 10,000, pot never below accountedPot, owner exclusion at record and close, bonus burn, and the fail-open reads. The seat read is gas-capped and cannot block a record. Points bound at 54 per plea and 162 per wallet fit the integer widths.
   • Agreed numbers. Every constant in the five files matches THREAT-MODEL section 2. The 20 + 20 minute hold sits inside the 1-hour close grace.

   Invariants checked: 1 through 13 of THREAT-MODEL section 2 for this area, with 14 to 22 only where the gate touches them.

   Test runs: Tribunal, Seasons, seat, gate, replay and oracle boundary suites, 195 tests in all, plus my 5 probe tests under test/scratch/, all passing. Not run: the fork suites, which need a live RPC. The live Intake's requests getter shape is taken on the strength of the Sepolia rehearsal and the fork tests, not re-verified here.

   • lowTribunal.status reports an overruled plea's raw score as its points, ignoring the seat multiplier and the points Seasons actually recordedsrc/Tribunal.sol:237

     The explorer line Tribunal.status(pleaId) ends an overruled case with · counts N points, where N = min(original score, lowest re-score). Since run 7 the points a plea counts are that score times 1.2 (rounded down) when the seller holds an IMD seat NFT at record time (Seasons.pointsFor, stored in Seasons.pointsOf(pleaId) once recorded). The Tribunal's line never reads either, so for every seat holder it states a points figure that is wrong before and after the recording.

     The same mismatch was fixed for the Letterbox's status line in R1-A2-5 (it reads Seasons.pointsOf once recorded); the Tribunal's line was not updated when the multiplier arrived.

     Display only: nothing on chain reads status, Seasons.record and pointsOf are correct (invariant 7 holds), and the Tribunal's sustain comparison correctly uses the unmultiplied score. Severity Low per THREAT-MODEL section 4 (display text). Merged from the audit_flow specialist's finding; reproduced against the code with the fixture below.

     Fix: once seasons.recorded(pleaId), print Seasons.pointsOf(pleaId); before that, print the score with the word scores (or pointsFor(seller, min) marked provisional), as the Letterbox does after R1-A2-5.

     whole finding

     Fixture with the Tribunal deployed (test/utils/Fixture.sol, withTribunal() = true). seat.mint(alice) so Seasons.holdsSeat(alice) is true. alice's plea is approved at score 40 (need 35 in the fixture). bob objects; the panel re-scores 38 (38 + 2 >= 35, so OVERRULED, case lowest = 38). skip(20 minutes + 1); anyone calls seasons.record(pleaId): Seasons.pointsOf(pleaId) == 45 (38 * 12000 / 10000) and bestOf(0, alice)[0] == 45.

     Expected: tribunal.status(pleaId) reports 45 points (or the recorded pointsOf).

     Actual (logged from the probe test): Plea #1 · objections closed · OVERRULED (38 vs need 35) · counts 38 points.

     The same line is shown before the recording, when the provisional figure for a seat holder would also be 45.
