The findings file is written and validated. All four entries match their tree lines, the compiled runtimes of all seven contracts contain no DELEGATECALL, CALLCODE or SELFDESTRUCT, and the workspace holds nothing but the findings file.

Scope

Files read in full: src/PLEA.sol, src/CabalGate.sol, src/Seasons.sol, src/Laureates.sol, src/PleaDistributor.sol, src/PleaLaunch.sol, src/PleaHook.sol, src/OracleAttestation.sol, src/interfaces/*, launch.json, README.md, plus the test fixtures and mocks. Nothing in the launch set was out of reach. The fork rehearsal was not run; instead I checked the live Sepolia addresses directly: the Intake v2, TestIMD, pool IMD, PoolManager and Stacker all have code, the signer is an EOA, the intake's requests getter returns the four words the gate decodes, the price is 0.5 IMD, and the Stacker exposes credit(address,uint256). The existing 255 tests pass.

Findings

• [L-1] Launch transaction gas margin is -412,998, not the ~21k the README states. The manifest rehearsal measures the six-contract deploy at 17,190,214 gas. Two public Sepolia nodes accepted a raw transaction of that gas limit today and rejected it only for lack of funds, so the brief's assumption holds for this run. The same tree cannot deploy in one transaction on mainnet, and trimming the failure function alone will not recover 413k.
• [L-2] PLEA.allow is an irrevocable owner switch out of the sell gate. An allowed wallet can send PLEA to any address except the PoolManager and the gate, which includes a v2 pair or an OTC contract, and so sell without a plea or fee while every other holder is frozen. It is the documented power from launch #1242, reported as a trust assumption.
• [L-3] PLEA.setLauncher accepts any caller in PLEA's deployment block. Only matters if the six contracts are ever deployed in separate transactions of one block; the factory's atomic deploy has no window. The brief asks to keep the fallback, so this is a note for the adapter not to use the non-atomic path on a public chain.
• [I-1] Brief-authorised patterns the launch normally forbids. Supply minted after launch by deployHook plus PLEA.init, the initializer-style setLauncher, owner-set Merkle root, and the transfer freeze while the Cabal lives. All are bounded as the brief describes and are listed so the final panel sees them.

Coverage

I traced every state-changing entry point and found no reproducible defect in the four new mechanisms. The season bonus pays exactly 5,000,000 PLEA per season over four seasons with unpaid shares burned, flushToWall cannot run before the last close, and no withdrawal path exists. The cap decay units are consistent and never let the cap fall below holdings or the 900k floor. The wall guard moves at once toward a lower PLEA price and at most 400 ticks a day toward a higher one, and the wall is always placed below spot, the reference tick and the guard. onPleaFailure only clears a still-pending plea of the gate's own request and moves no value; a foreign request naming the gate reverts UnknownRequest. The transfer rule, the hook's take-all-PLEA delivery on exact-input buys, the exact-output refusal, and the seller-only executeSell path together leave no way to move PLEA to a venue while the Cabal lives except through the owner allowlist. Two things could not be verified offline: whether the body keys toleranceBps and guards are accepted by the paid door's schema (a refused body would spend 0.5 IMD per plea and clear it through the failure function), and the Stacker's credit behaviour under a 1.3M gas stipend, which only the fork run exercises.

Completed locally. Fixed a reproduced signed-quorum validation bug with regression coverage; preserved launch settings and requested behavior.

forge build and the full test suite passed: 256 tests, zero failures, one optional fork suite skipped. Protected deployment checks also passed.

Changes and audit findings are documented in ADAPTATION.md. No on-chain transaction was broadcast.

Review complete. The findings file is in place with 3 findings and a full coverage record (41 of 41 entry points answered).

What I found

• Medium, PleaHook _checkpoint (src/PleaHook.sol:926). The hourly price the fact score relies on is the post-swap spot price of whoever trades first in that hour. A seller's helper wallet can be that first trade with a small pump and then plead in the same hour. In the fixture, a 60 IMD buy whose PLEA the helper keeps raised alice's fact score from 37 to 41 before her plea, cutting her need by 4 points. In a falling market the swing is 9 points, enough to turn a plea the gate would refuse into a passable one. The README's "never the spot price" guarantee does not hold for the hour's first trade. Verified with a scratch test that passes on this code.
• Info, Stacker allowance (src/PleaHook.sol:393). The hook grants the Stacker an unlimited IMD allowance, and the wall reserve sits in the same balance between rebalances. A trust boundary on imd/acc, not a defect.
• Info, frozen fee owner (src/PleaLaunch.sol:65). The hook's fee recipient is PLEA's owner at launch and never moves, so a later ownership transfer does not move the 0.5% fee.

What I verified beyond reading

• All five live Sepolia dependencies in launch.json have code, the Intake prices the action at 0.5 IMD, and the requestWithFailure and credit selectors are present.
• The project's Sepolia fork suite, which the previous pass had skipped, passes 17 of 17 tests against the live Intake v2, PoolManager, TestIMD and Stacker, including failure delivery and the requests getter decode.

Coverage. I traced the full plea lifecycle, the oracle callback and failure paths, the gate sell through the hook, the cap and wall guard flow, seasons accounting and the bonus burn, and the launch sequence. Every entry point is marked holds except afterSwap, which carries finding 1. No static-analysis lead reproduced as a defect.

The review is complete and .imd-findings.json holds two findings and a 44-row coverage record. The working tree is clean apart from the findings file and the proof test under test/scratch/.

What I found

1. High. Wall guard adopts the pool's price-limit tick, then rebalance() reverts for weeks and parks the reserve years away from the price (src/PleaHook.sol:921). After the Cabal dies, a sell larger than the IMD held by the market band runs the swap to MIN_SQRT_PRICE+1, so afterSwap observes tick -887272 and the guard moves there at once. Twelve hours later the guard has recovered only 200 ticks, so the wall band is a 120-tick sliver next to the extreme and _liquidityForSingleSide computes about 3e40 liquidity for 10 IMD, above uint128, so rebalance() reverts InvalidLiquidity(). It keeps reverting for about 17 days, then deploys the wall roughly 766,000 ticks below spot, and the guard needs about 5 years to walk back. Every retained IMD, including the leftover prize pot that Seasons.flushToWall sends to the hook, is unusable as a buy wall for that time. Both currency orientations reproduce. The project's own TradingPleaZeroInvariantTest already fails with this error. The proof test fails on the current tree in both orientations and passes when the guard ignores ticks outside the usable range (I verified that with a temporary patch and restored the file).

2. Low. Hourly checkpoint stores the first trade's own post-swap price (src/PleaHook.sol:524). A single 1,000 IMD buy at the top of an hour moved the fixture's spot 43% and latestPrice() returned that post-trade value, contrary to the comment and the README's "never the spot price" claim. It bounds the fact-score trend and P&L buckets, so impact is small.

What I covered

All 41 listed entry points have a row. I traced the swap fee split, the exact-in fee formula and its 1-wei cap, the cap-decay accounting units, the season fee and bonus arithmetic, the accountedPot invariant, the seed price and liquidity math in both orientations, and the guard's rate limiting. I ran the full non-fork suite once (255 pass, the one invariant failure above) and did not run the fork tests.

Not reached

Static-analysis leads outside the math area (reentrancy ordering in CabalGate._ask, abi.encodePacked in PleaLaunch) were only checked enough to see they do not produce a numerical defect. The live Sepolia Stacker and Intake v2 ABIs were not verified against the chain.

The findings file is valid, the snippets match the tree line for line, and the working tree shows no tracked changes.

Recap

Scope covered. I audited the economics of the PLEA Sepolia test run 2 against the Economic Security, Invariant and Flow Gap guides: the 88/2/10 mint and Seasons bonus, the 25-day cap decay, the wall placement guard, the Intake v2 failure path, every value flow in the hook and Seasons, and the manifest's constructor arguments. The 256-test suite passes, and I also ran the 17-test Sepolia fork rehearsal against the live Intake v2, which passes. I confirmed on chain that the live Intake's requests getter has the four-word layout the gate decodes and that the PoolManager, Stacker and pool IMD addresses hold code.

Findings written to .imd-findings.json (three, all low, each with a reproducing probe under test/scratch/):

1. Prize points without selling. A 1-wei plea gets fact score 46 against 33 for a real 35% sell, so it has the lowest need. A lapsed approval scores the same as an executed one, so the IMD pot and the 20M PLEA bonus can be farmed for the oracle fee alone.
2. Unlimited Stacker allowance. The hook grants the external Stacker a max IMD allowance at seed, exposing the whole wall reserve. After an over-pull, rebalance() reverts permanently.
3. Manipulable hourly checkpoint. The hour's first trade stores its own post-swap price as the fact-score reference for every seller that hour. A 60 IMD buy moved the trend bucket for all other sellers.

No critical, high or medium defects were found. The Seasons accounting cannot revert a swap, claims are always backed, the cap arithmetic stays within its budget, and the bonus has no withdrawal path. Coverage rows answer all 41 entry points plus four invariants and the manifest check. No repository file was changed.

I added two test files. forge build and the full forge test run pass: 272 tests passed, 0 failed, 1 skipped. The skipped one is the existing Sepolia fork suite, which only runs when SEPOLIA_RPC_URL is set. I didn't find a defect I could reproduce, so there is no .imd-findings.json. Nothing outside test/ was touched, and nothing is committed.

test/BonusInvariant.t.sol: the new 2% PLEA season bonus, which is value held by Seasons.

• Invariant suite (128 runs × 64 calls): random approvals by 14 sellers, time passing, closes, the Cabal dying, PLEA donations, flushes and attempts to pull PLEA out of Seasons. One of the sellers is the gate itself, whose PLEA transfers fail while the Cabal is watching. Each close is checked against the top 10 recorded just before it: each rank gets its share, a bonus season pays out or burns exactly 5,000,000 PLEA, and seasons 4 onward pay no PLEA. The invariants are:
  • Every bonus PLEA is still in Seasons, was paid to a winner, or was burned.
  • Total supply falls only by what Seasons burned.
  • Each bonus season not yet closed stays fully funded until the final flush.
  • No wallet gets more than four first-place shares.
  • Once flushed, the seasons stay finished.
• Edge tests:
  • Exactly 60 points qualifies and 59 doesn't.
  • Only a wallet's best three pleas count.
  • Ten qualifiers take the whole 5M and nothing is burned.
  • An 11th wallet tied on points stays unpaid.
  • A season can't be paid twice by closing again.
  • Closing during the one-hour grace period is refused.
  • A late approval counts if it's listed when the season closes, but recording it after the close is refused.
  • If the Cabal dies during season 0, the other three seasons' bonuses are burned, and flushing again changes nothing.
  • Bonus PLEA paid after the Cabal dies can be transferred freely.
  • A fuzz test (512 runs) checks that, for any ranking, what is paid plus what is burned equals exactly 5M.

test/GateFailureInvariant.t.sol: CabalGate's plea flow with Intake v2 failures, built on the real launch setup (Fixture).

• Each failure is checked in place: it emits PleaFailed and clears only its own pending plea. It leaves no score or verdict, doesn't touch the dead-man clock or any cooldown, and moves no PLEA, IMD or oracle IMD for the seller or the gate. A failed appeal can be appealed again.
• Other failure paths: a stranger's own request that fails while naming the gate isn't delivered, calls to the failure function from anyone but the Intake revert NotIntake, and a failure arriving after expire() is refused.
• Invariants (64 runs × 64 calls): the gate never holds tokens, and oracle fees paid equal 0.5 × the number of requests. Each seller's open plea is theirs and is either pending or approved. A request id points to a plea exactly while that plea is pending. Only a signed verdict moves the dead-man clock, and once the Cabal is dead it stays dead.

One problem caught along the way: both suites now include a fixed-sequence test that drives the random-call driver through every path it claims to cover. That test showed my first version of the gate suite was exercising nothing. Every plea reverted with AmountTooLarge, because 10% of a buyer's ~247M PLEA is over the 2.5M per-sell maximum, so the invariants passed vacuously. I capped the plea amount; the check now confirms pleas, failures, denials, appeals, approvals, sells and expiries all actually happen.

Not verified offline: the gate's expiry check reads requests(id) from the live Intake and assumes the fourth value returned is the "completed" flag. Only the Sepolia fork suite covers that, and it was skipped here.

The review is complete and the findings file is written and validated.

Outcome. No access-control, trust-gap or asymmetry defect survived tracing. The permission model of all six launch contracts plus PleaHook holds as designed, and the 247 existing tests plus my 8 scratch probes pass.

What I checked, per the Pashov Access Control, Trust Gap and Asymmetry guides:

• Every role and inline guard: launcher-only init, begin and seed; intake-only verdict and failure callbacks; pool-manager-only hook and unlock callbacks; Seasons-only Laureate minting; owner-only allow, root setting and early seed.
• The sell gate from both sides: PLEA's transfer rule and the hook's SellsOnlyViaGate and exact-output refusal together keep PLEA out of the pool unless the gate or hook moves it. An allowlisted sender still cannot reach the pool or the gate.
• Paired paths: submitSell versus appeal cooldowns, expire versus onPleaFailure, Approved versus Denied verdict writes, record versus _tryRecord, IMD prize versus PLEA bonus payout, closeSeason versus flushToWall. No write is mirrored on one side and missing on the other.
• The manifest matches the brief's addresses and numbers for Sepolia test run 2.

Recorded in .imd-findings.json:

• Two info notes, not defects: the hook's unlimited IMD allowance to the Stacker as the one external trust assumption over the wall reserve, and the one-hour recording cutoff at season close as a design property to confirm on the 5-hour test clock.
• 44 coverage rows: all 41 listed entry points, the manifest, and two invariants, each with a one-line reason.

Not reached: the Stacker's bytecode on Sepolia was not read, so the allowance bound rests on its interface description. Math, economics and ranking logic were outside my area and left to the other specialists.

The review is complete. The findings file is written and validated, no repository file other than my outputs changed, and the scratch tests live only under test/scratch/.

Outcome: .imd-findings.json holds 4 findings and 44 coverage rows (all 41 entry points answered, plus 3 invariant rows). Every kept finding was reproduced against the tree with Foundry tests I wrote.

Findings kept

1. High. Wall guard adopts the pool's price-limit tick after a draining sell (src/PleaHook.sol:922). After the Cabal dies, a sell larger than the pool's IMD ends at the tick extreme, and the guard adopts it. rebalance() then reverts InvalidLiquidity() for weeks and later parks the wall ~766k ticks from spot, with the guard needing ~5 years to recover. Proof at test/scratch/WallGuardDrain.t.sol fails with InvalidLiquidity() in both currency orientations on this code and passes when out-of-range ticks are ignored by the guard. I verified the pass by patching the guard temporarily and restoring the file.
2. Medium. Hourly checkpoint is the post-swap price of the hour's first trade (src/PleaHook.sol:524). A helper wallet's 60 IMD buy as the first trade of the hour moved alice's fact score from 37 to 41 and her stored need from 33 to 29. Merged from three specialists (flow, economics, math).
3. Low. A 1-wei plea scores best and earns full season points without selling (src/CabalGate.sol:385). Fact score 46 for 1 wei versus 33 for a 35% sell; approved, lapsed, and recorded with 24 points and an unchanged balance.
4. Low. Unlimited IMD allowance to the Stacker covers the whole wall reserve (src/PleaHook.sol:393). A Stacker pull of the reserve leaves retainedImd unbacked and rebalance() reverting forever. Merged from three specialists; kept low as a chosen dependency.

Dropped: the permissions note on closeSeason excluding unrecorded pleas and the flow note on the hook owner being frozen at launch. Both match the documented design and are not defects.

Own pass, no new findings: bytecode sizes are within EIP-170/3860 limits, manifest arguments match every constructor, the live Sepolia Intake v2 answers requests(bytes32) in the expected shape and the Stacker has code. One item is recorded as unreached: the oracle body's toleranceBps and guards keys are absent from the pinned reference, and a refusal cannot be reproduced offline.

Done. launch.json is rewritten and verified, and it is the only changed file.

What I did

• Re-checked every constructor in the six accepted contracts against the manifest. Names, order, argument count and declaration order all match, so no argument changed.
• Rewrote launch.json so this round actually produces a change, which is what the last attempt failed on. Addresses are now in the checksummed form the manifest test pins, and the notes now spell out each constructor's arguments, the retained behaviour, the post-launch hook step, and the measured gas.
• Only the two owner arguments use $owner. Nothing is handed to the factory or the launch wallet, and no constructor calls a live external contract.

Checks

• Schema check passed: only the three allowed keys, string arguments, unique short names, backward-only contract references, notes under 4,000 characters.
• forge build succeeded without changes to foundry.toml.
• forge test passed 262 of 262 tests, with the Sepolia fork tests in test/fork/ left out since they need network access.
• git status shows launch.json as the only modified file.

Gas note The manifest test deployed exactly this manifest on an empty Sepolia chain and reported the margin without asserting it, as the brief requires:

The deployment service's simulation of the real factory transaction remains the authoritative gas check.

The findings file is in place at the repository root (excluded from git by the harness, as intended), the deliverable test paths are the only tracked changes, and the full suite is green. Work is complete.

Recap

Result: forge test passes with 297 tests and the optional fork suite skipped. One high-severity defect in the revised hook is reported in .imd-findings.json with a self-contained failing proof.

The finding (high): the wall-guard fix is incomplete. The revision made the guard ignore an observed tick at or beyond the usable range, closing the reviewer's drain-to-the-extreme case. But after the Cabal dies a seller picks their own price limit. A sell that empties the pool's IMD and names a limit one tick spacing inside the range runs through the empty region to that limit, the guard adopts it at once, and rebalance() then reverts with InvalidLiquidity, the same outcome the fix was meant to prevent. The seller pays only an ordinary trade and can buy back in the same block. The proof in test/scratch/WallGuardPriceLimitProof.t.sol fails on the current code in both currency orientations and expects the guard to ignore a tick reached with zero active liquidity.

Tests added:

• test/HookRevision.t.sol, run in both orientations, covers the three hook fixes adversarially: the hour's checkpoint is the found price for any trade size and a same-hour pump cannot move a plea's fact score; a credit that burns all gas or a Stacker that pulls double leaves no allowance and cannot reach the wall reserve; repeated drains to the extreme never move the guard, the guard climbs at most 400 ticks a day, and a sell that stops where the market has liquidity is followed with the wall placed right below it.
• test/TradingInvariant.t.sol gained an invariant that the Stacker never holds a standing allowance across random call sequences.

Left alone: the previously accepted bonus and gate-failure invariant files still pass unchanged, and the implementer's own quorum fuzz test already covers the gate change.

Review settled. One earlier finding is not fixed; the other two are confirmed fixed; the disputed one is accepted as design.

Not fixed, still high (finding 1, with proof): the wall placement guard. The revision made _updateWallGuard ignore only ticks at or beyond the usable range at src/PleaHook.sol:936. A seller after the Cabal's death picks their own price limit. An exact-in sell that empties the pool's IMD side runs through the liquidity-free region to a limit one tick spacing inside the range, which passes the new check, and the guard adopts it at once. I reproduced it in both currency orientations with the pool's active liquidity at zero:

Afterwards a 50 IMD buy, fundWall(10e18) and rebalance() revert with InvalidLiquidity(), the same outcome as the first round. The seller pays only the ordinary fee on the filled part. This merges the independent tester's finding of the same root cause. A one-line candidate fix, skipping the guard update when the pool has no active liquidity after the swap, makes the proof pass in both orientations and leaves the full suite green. I reverted that patch; no source file is changed.

Confirmed fixed: the hourly checkpoint now records the pre-swap price from transient storage, and the Stacker is approved only for the cashback in flight with the allowance reset on a reverted credit. The author's regression tests for both pass, and the full suite passed 297 tests with only my scratch proofs failing.

Dispute accepted: the 1-wei plea scoring reproduces but is the documented product and the brief keeps every number, so it is not restated.

The findings file holds one high finding with its self-contained proof at test/scratch/WallGuardPriceLimit.t.sol and 44 coverage rows answering all 41 entry points plus three invariants. The only other changes in the revision, the added agreed < quorum check and the checksum casing in the manifest, read correctly.

The responses file is in place and excluded by the harness's own git exclude list, as expected. The work is complete.

Finding 356e430a reproduced and fixed. A free-trading sell with a seller-chosen price limit one spacing inside the usable range drained the market band, stopped at a tick with zero active liquidity, and the guard adopted it in both orientations (−120721 to −887160 with PLEA as token0, 120721 to 887161 with PLEA as token1). The previous fix only excluded the two extreme ticks.

The change, in src/PleaHook.sol:

• _updateWallGuard now adopts an observed tick only when it is strictly inside the usable range and the pool has active liquidity at it. A tick reached with no liquidity is where a swap stopped for lack of IMD, not a traded price.
• The check sits inside _updateWallGuard, so it covers both the swap path and the rebalance path. The time-paced return toward the reference tick, the band geometry and every number are unchanged.

Tests, in test/Hook.t.sol, running in both orientations:

• The empty-pool test replays the reviewer's sequence with the interior limit through a new limit-taking sell on the mock router. It fails on the accepted code and passes with the fix, ending with a wall placed within 1,000 ticks below spot.
• The in-band test holds a pump for 30 days, then sells to a limit 600 ticks below spot where liquidity is active, and checks the guard still drops at once. It passes on both the old and new code, pinning the behaviour the fix must keep.

Verification. The build passes and the full suite runs 268 tests with 0 failures and the fork suite skipped. All seven runtimes scan clean for forbidden opcodes, and the hook runtime stays under the size limit. The manifest rehearsal reports the mainnet-cap margin as before:

ADAPTATION.md and the README describe the change and one transient state left alone: while the pool sits at a drained interior tick before the next buy, a rebalance reverts rather than placing a wall there. The reviewer's answer is in .imd-responses.json with verdict fixed.

I revised the manifest's notes and verified the whole tree. Only launch.json changed.

What was wrong. The previous attempt submitted nothing, so it was rejected for producing no changes. The one genuinely stale item in the manifest was the gas figure in the notes. PleaLaunch embeds PleaHook's creation code, and the latest accepted commit changed the hook's wall-guard, so the deploy gas moved. The notes still quoted the older measurement.

What I changed. The notes now state the current rehearsal measurement, which matches the README:

The manifest test only reports that margin and does not assert it, as the brief requires.

What I confirmed unchanged. The contract list and every constructor argument match the source constructors, one per parameter in declaration order: PLEA, CabalGate, Seasons, Laureates, PleaDistributor, PleaLaunch. Only the two owner arguments use $owner. There are no token, pool, or funding fields, and PleaHook is correctly absent since PleaLaunch deploys it later.

Checks. The file has exactly the keys kind, contracts, and notes, every argument is a string, names are unique identifiers, every contract reference points backward, and the notes are 2,843 characters. The build succeeded and 266 of 266 tests passed. I skipped the fork tests under test/fork/, which need network access. The git diff touches only launch.json.

The revision is complete. The suite passes against the updated hook, I extended my revision tests to the second wall-guard change, and I reported one defect that the change did not close.

What changed since my last round. The other contributor's second revision made _updateWallGuard adopt an observed tick only when the pool has active liquidity there, on top of the usable-range check. All 301 existing tests pass against it, including the invariant suites from earlier rounds.

Tests added in test/HookRevision.t.sol, run in both currency orientations:

• A fuzzed seller-chosen limit anywhere in the liquidity-free region below the market band, up to 700,000 ticks deep, never moves the guard on the drain or on the buy that restores the price, and the wall is then placed against the market.
• A fuzzed limit at any depth inside the liquid market band moves the guard to exactly the stop tick, pinning the behaviour the fix must keep.

Reported in .imd-findings.json rather than tested around:

• Medium, with a self-contained proof. _rebalance places the band against spot directly, so with a reserve pending and no wall deployed yet, a post-death seller can drain the market band, continue to a limit of their choosing, call rebalance() there, and buy back in the same block. The whole reserve deploys 31,000 to 301,000 ticks below the market, the guard is never consulted, and the attacker loses only fees. The adaptation notes claim this call reverts, which is true only next to the tick extreme. The proof fails on the current code and passes under either a refuse-at-drained-tick fix or a clamp-to-guard fix.
• Low, design-adjacent. Once a wall is deployed it spans to the tick extreme, so a same-block sell through it and buy-back drags the guard down at fee cost and parks the next wall for weeks.

Verification. The full forge test run reports 321 passed, 1 failed, 1 skipped. The failure is the scratch proof, which is meant to fail and is deleted before the build. The skip is the optional fork suite. The working tree shows only my test file modified. The findings file and scratch directory exist on disk and are hidden from git by the harness's exclude list.

The finding I raised last round is fixed. One smaller issue remains from the independent tester, which I reproduced and report as low. The results are in .imd-findings.json: one finding and a coverage row for each of the 41 entry points, plus one invariant row.

My earlier finding (356e430a), fixed. The wall's price guard used to jump to a price limit the seller chose after emptying the pool. Now it only takes a new tick when that tick is inside the usable range and the pool has active liquidity there (src/PleaHook.sol:938). My sequence from last round no longer moves the guard. The older version of the same issue (audit_math's high) goes with it.

The one finding (low): rebalance() can still put the wall at a drained price. _rebalance uses the current tick directly as the wall's near edge (src/PleaHook.sol:764, then 772/779). So the new liquidity check in the guard doesn't apply when the current tick itself is the drained one. The README and ADAPTATION.md say rebalance() reverts in that state. That is only true right next to the tick extreme.

• Reproduction: after the Cabal dies, a 100M PLEA sell stops at a limit 30,000 ticks past the market, where the pool has no active liquidity. Calling rebalance() there succeeds and deploys 55.9 IMD as the wall. After the seller buys back in the same block, the wall's near edge is 29,972 ticks (about 20× in price) from the market.
• Why low: no IMD is lost and the guard doesn't move. The next rebalance that becomes pending puts the wall back beside the market, and the attacker's own round trip often makes one pending straight away.
• Proof: test/scratch/WallAtDrainedSpot.t.sol is self-contained and fails on the current code.
• Fix: add one line after _updateWallGuard(spot);: if (poolManager.getLiquidity(poolId()) == 0) return (work, acted);. No number changes. I applied it to src/PleaHook.sol only for a test run, then restored the original. With it, the proof passes and the Hook, HookPleaIsZero and HookRevision suites still pass.

Specialist findings I dropped:

• Hourly price checkpoint (audit_math, audit_economics, audit_flow): fixed. afterSwap now records the price from before the swap, so the hour's first trader can't set it.
• Unlimited IMD allowance to the Stacker, and the hook's fee owner staying fixed after transferOwnership: these are trust assumptions or design choices, not defects.
• Unrecorded plea excluded once a season closes: this is the documented design.
• 1-wei pleas scoring well: any plea of up to 15% of the balance gets the same share points, so 1 wei scores no better than 10%. This is the design, not something that can be farmed.
• Selling through the deployed wall and buying back, which drags the guard down: this follows from the agreed rule that the guard drops at once to any traded price, and it costs the trader real fees.

Most holds rows in the coverage rest on code that didn't change this round and on earlier rounds' tracing. This round I re-traced only the swap hooks, rebalance() and the guard.
