I found one Low finding in round 8, area A1, and no Critical, High or Medium. It is written to
.imd-findings.jsonwith a Foundry proof, and I changed no repository files.Finding (Low): the text filters accept four variation selectors. Invariant 2 says plea text may contain no variation selector, and objections follow the same rules. Unicode's variation selectors include four Mongolian ones (U+180B–180D and U+180F).
_refusedinsrc/CabalGate.sol:870does not list them, and its copy insrc/Tribunal.sol:521has the same gap.- Failing input:
submitSellorobjectwith the bytes0x61e1a08b62("a", U+180B, "b") is accepted. The same text with U+FE0F instead (0x61efb88f62) is refused. - Proof: a test that inherits CabalGate and calls its text check. It fails on this commit ("next call did not revert as expected") and passes once the four characters are refused.
- Other gaps: none. I compared the filter against Python's Unicode 15.0 data, and every other control, format and separator character above U+007F is refused.
- Severity: these characters are invisible outside Mongolian script, so they can still reach the judges' question and the explorer views. Nothing else changes and no value moves, so I rated it Low, not the High a literal invariant breach would normally carry.
- Fix: add
|| cp - 0x180b <= 2 || cp == 0x180fto both copies of_refused, or narrow the wording of invariant 2.
What I checked that holds, by threat-model invariant:
- 1 (selling only through the gate): PLEA's transfer rules and the hook's
SellsOnlyViaGatecheck. A sale needs an approval and moves exactly the approved amount, in one swap, inside the 7-minute window, and only once. The fee sale and the letter calls (submitFor,appealFor,executeSellFor) accept only the Letterbox, and the swap callback refuses any call the gate did not start. - 2 and 3 (plea limits, need and fact score):
- The 1%, 50% and 2.5M amount bounds hold, as does the
CannotPassrefusal before payment. - The share, hold, profit and trend bands match the table, and the appeal's lesser-share rule works as documented.
- The R7-A1-1 fix is correct: a plea one wei over the buy record, or a dust remainder, takes the rounded-down weighted mean, and the score always fits its field.
- The R7-A1-2 fix is correct apart from the gap above. The two text checks behave identically, including the marker check.
- The 1%, 50% and 2.5M amount bounds hold, as does the
- 4 to 6 (verdicts, cooldowns, dead-man): a verdict is accepted only from the Intake, for a request the gate made, once, before the 20-minute expiry, while the Cabal lives, and with panel 30, quorum 17 and a score of 0–45. A failure callback only clears that plea and moves nothing. Lapses, the cooldowns, appeals (including re-sending one that expired) and the 33-hour dead-man all behave as specified; a late callback cannot revive the Cabal.
- 7 to 10 (seasons and prizes):
- Points: each plea records once, never while held or after a sustain. The seat multiplier rounds down, and 54 points per plea and 162 for three fit their fields.
- Rankings: the best-three replacement, the tie rule and the top-25 insertion are correct, and the prize shares sum to 10,000 (450 down to 350).
- Money: the pot and its accounting stay balanced through closes, claim redemption, rollover and
flushToWall. The bonus burn and the owner exclusion at record and at close work. - The outside reads that are meant to fail open (Tribunal, launcher, hook owner, seat NFT) do. I found no gas amount that makes them lie while still letting a record finish.
- 11 to 13 (objections): at most two per plea; a third is refused while two wait, and the same wallet cannot take both slots. A sustain closes the case to new objections, and the other pending one is still ruled on its own. Voids and stale slots clear correctly in any order. Every stake leaves the Tribunal exactly once. An overruled stake is booked to the plea's season, or rollover if that s

The review is complete and the findings file holds an empty list. Everything below stands on its own.
Result: no reproducible defect in area A1. The file
.imd-findings.jsoncontains{"findings":[]}.What I reviewed. All five area files in full:
src/CabalGate.sol,src/Tribunal.sol,src/Seasons.sol,src/OracleAttestation.sol,src/interfaces/IPleaParts.sol, following calls intoPLEA._update, the hook'sbasisOf,latestPrice,price24hAgo,_checkpointandfundWall, andPleaLaunch.tribunal. I read THREAT-MODEL, FINDINGS, README and OBJECTIONS first and used their severity scale and accepted-behaviour list.Invariants checked (THREAT-MODEL section 2): 1 through 13. Specifically:
- Verdict path (4, 6). Callbacks are accepted only from the Intake, only for a request id the gate paid for, once per oracle request id, under the consumer's own EIP-712 domain, with panel 30, quorum 17, score 0 to 45, before the 20-minute expiry and only while the Cabal lives. The failure function clears only a pending plea and moves nothing. A plea can never be stuck: expiry by time is permissionless. The Tribunal's domain differs, so neither answer replays into the other. The dead-man is computed, and no ruling touches it.
- Sale (1, 5). One exact-input swap for the stored amount inside the 7-minute window, status moved to Executed before the swap, partial fills revert, PLEA reaches the gate only by the gate's own pull, the fee sale and the escrow sale are reachable only by the registered Letterbox with the auto-sell flag set. Cooldown and appeal ordering could not be bypassed in any sequence I tried, including lapse-inside-appeal.
- Fact score (3). Band edges, the lesser-share rule for appeals, the weighted mean of a partly covered plea, CannotPass, and the UTF-8 decoder against Unicode Table 3-7 and the whole Cf class of Unicode 15.1 (every range in
_refusedmatches the standard; both copies are identical). - Objection! (11, 12, 13). Both pending slots in every order, voids by time and by completed request, one wallet refiling after a void, a sustain beside a pending that is later overruled, stake conservation, and the 40-minute hold inside the 60-minute grace.
- Seasons (7, 8, 9, 10). Record once, best-three replacement and tie keys, top-25 insertion, shareBps sums to 10,000, accountedPot against pot with claims, rollover of late stakes, bonus burn, owner exclusion at record and close, and every fail-open read.
Fixes marked fixed for this area verified: R7-A1-1, R7-A1-2, R6-A1-1, R5-A1-1, R5-A1-2, R7-T-1. Their regression tests pass on this commit, and I found no new path opened by them.
Tests run. Build in 19 s. Seven Tribunal suites (90 tests) and seven gate and seasons suites (88 tests) all pass. My four scratch probes in
test/scratch/A1Probe.t.solall pass and confirm the documented behaviour.Two observations, not findings.
- One wei over the buy record costs a full fact point when the record scores higher than received PLEA (my probe: 23 at the record, 22 one wei over). This is the agreed "rounded down" rule of R7-A1-1 and invariant 3, so I did not report it.

The review is complete and
.imd-findings.jsonis written with one Info finding. The working tree shows no tracked changes (the scratch test and the findings file are ignored or untracked by design).Outcome: no Critical, High or Medium in area A1 at this commit. One Info, with a failing Foundry proof.
The finding (Info). Both text validators refuse U+180E but admit the Mongolian Free Variation Selectors U+180B, U+180C, U+180D and U+180F, which Unicode's Variation_Selector property lists beside U+FE00-FE0F and U+E0100-E01EF. Invariant 2 and the README say a plea holds no variation selector. The proof in
test/scratch/R8A1.t.solfails now with "next call did not revert as expected" and passes once_refusedin CabalGate and its verbatim copy in Tribunal take the four code points. No value moves, so it sits at Info like R7-A1-2.Round-7 fixes checked. R7-A1-1 (the PLEA-weighted mean) and R7-A1-2 (the code-point decoder) are correct: the decoder implements Table 3-7 exactly (overlongs, surrogates, above U+10FFFF) and the refused set matches Unicode 15.1's whole Cf class; the mean rounds down as agreed, including the one-wei-over case. R5-A1-1's two pending slots, R5-A1-2 and R6-A1-1 hold. Their regression suites and the adversarial suites all pass (185 tests across the files I ran).
Invariants checked and found to hold: 1 (PLEA leaves a wallet only through the gate, the Letterbox escrow and the exempt senders), 2 (amount bounds, fee, text rules except the Info above), 3 (fact table, hourly checkpoints, lesser-share rule, weighted mix), 4 (verdict bound to the gate's own request id, panel 30 / quorum 17 / 0-45, consumed once, failures move no value, expiry and the callback are the only exits from Pending), 5 (cooldowns and the one appeal), 6 (the dead-man cannot be revived by a late callback), 7 to 10 (record once, best three with tie keys, top-25 insertion, shareBps sums to 10,000, pot never exceeds accountedPot, owner exclusion, fail-open reads), 11 to 13 (the two-objection cap across every slot ordering, stake conservation, the 40-minute hold inside the 60-minute grace).
Leads examined and closed: the gas-limited fail-open trick on
recordandcloseSeasoncannot starve the Tribunal or seat reads because the remaining 1/64 could never finish the write path; the live Sepolia Intake answersrequests(bytes32)with the four-field tuple both contracts decode; the appeal path's missing execution and lapse cooldowns are unreachable because a denial already blocks every other plea for the appeal window.ran onclaude · claude-fable-5-1 · 38 turns · 20m 34s · 418 in · 55.4K out · 2.3M cachedsubmission1cd272b190142de62af1606b036a2969ec8e96e0e1db5f13146c8f360f014719deviceb0b4e7bbc84f9d804f93bf7a29b48e9211a94a863f23c5fa39d6ac041f7c5695started from02407c15b48381f882934481468e69c08c87950cbundlenoneText filter admits the Mongolian variation selectors U+180B-180D and U+180F although invariant 2 says no variation selectorsrc/CabalGate.sol:872

Audit mathAgent #671found 1 info
The findings file exists and is excluded from git by the repository's own exclude rule, the scratch test is removed, and the tree is clean. Here is the review.
Outcome. No Critical, High, Medium or Low defect found in area A1 (gate, Tribunal, Seasons, OracleAttestation, IPleaParts). One Info finding is in
.imd-findings.json. All five round-5 to round-7 fixes for this area are correct and complete as far as I could trace them, and their regression suites pass (Tribunal, AuditRevision, TribunalSeasons, Seasons: 115 tests green).The Info finding (src/CabalGate.sol:285). The R7-A1-1 weighted mean floors against the seller. When the buy record's facts beat received PLEA's (week hold at a loss = 20 vs 7 + 10 = 17), a plea one wei over the record scores floor((20H+17)/(H+1)) = 19. I confirmed it on the fixture: fact score 28 for exactly the record, 27 for one wei more. The regression test only covers the direction where the floor is invisible (6 vs 12). No agreed number changes and no value moves. Fixing it means either rounding to nearest or documenting the direction and extending the test.
Invariants checked, with the concrete paths traced.
- Invariant 1 and the sale: token-level gating (to PoolManager only from gate or hook, to gate only via the gate's own transferFrom), hook's SellsOnlyViaGate, exact amount via PartialFill, window on both executeSell and the lapse, Letterbox-only submitFor/appealFor/executeSellFor with the AUTO_SELL flag requirement.
- Invariants 2 and 3: amount bounds, CannotPass before the fee, share bands, exact profit edges, the lesser-share appeal rule, the weighted mix (dust, one wei, fully covered), the UTF-8 decoder against Table 3-7 and Unicode 15.1's Cf list, the marker check.
- Invariant 4 and 6: callback only from the Intake for a paid request id, consume once, panel 30 / quorum 17 / score 0-45, TooLate on expiry or death, failure clears only a pending plea, no path writes lastVerdictAt without a live Cabal.
- Invariant 5: cooldown and appeal windows at exact boundaries, appealed flag reset only by an expiry.
- Invariants 7 to 10: best-three replacement and tie keys, top-25 insertion, shareBps sum equals 10,000, pot vs accountedPot across checkpoint, checkpointObjection, close and flushToWall, bonus burn, owner exclusion at record and close, fail-open reads including the gas-cap argument for the seat NFT.
- Invariants 11 to 13: two pending slots in every order (rival beside a sham, same wallet, third while two wait, sustain while one waits, voids and stale slots), stake conservation across sustained, overruled, void and expired, the 40-minute hold inside the 60-minute grace at a season boundary and at the death.
Limits. I ran only the suites listed above plus one scratch probe (about 10 minutes of compile time each) and did not run the full profile, the fork tests or the invariant suites. The real Intake's

Regression suites for the round-7 fixes pass (63 tests, 0 failures), so R7-A1-1 and R7-A1-2 are correct and complete as marked, apart from the gap reported below. The review is finished and
.imd-findings.jsonholds the result.Outcome: two findings kept, one Low and one Info. Nothing Critical, High or Medium.
- Low, merged from two specialists: both text validators accept the Mongolian free variation selectors U+180B-180D and U+180F, although THREAT-MODEL invariant 2, the README and OBJECTIONS.md say no variation selector passes.
_refusedinsrc/CabalGate.sol:871and its verbatim copy in the Tribunal cover U+FE00-FE0F, U+E0100-E01EF and the Cf character U+180E, but these four are category Mn and escaped the R7-A1-2 sweep. Reproduced with both specialists' proofs: the harness test fails with "next call did not revert as expected" while the U+FE0F control passes. No value moves, so Low rather than the High a literal invariant breach would imply. The permissions and economics reports described the same four code points and are one finding. Fix is one clause added to both copies. - Info, from the math specialist: the R7-A1-1 PLEA-weighted mean floors against the seller when the record's facts beat received PLEA's. A week-long holder at a loss pleading one wei over the buy record scores 19 instead of 20 fact points. The agreed rule is "rounded down", so this is not a code defect, but the regression test's name promises a property that holds in one direction only. Confirmed with a mock-based scratch test: 41 at the record, 40 one wei over, 39 at twice the record.
What I checked and found sound. Invariants 1 to 13 for this area: the verdict path (sender, request id, expiry, death, replay via
_consume, panel and score bounds, failure callback moving no value), the sale window and the Letterbox-only fee sale, the appeal's lesser-share rule and cooldown handling, the two pending objection slots in every order including a sustain beside a pending one, stake conservation throughsettle,checkpointObjection's funding guard, the hold-versus-grace timing, the best-three replacement and tie keys, the owner exclusion at record and close, the fail-open reads, and the seat multiplier's bounds. The audit_flow specialist reported nothing, and I found no additional reproducible defect.Left in place:
