• 1.mediumReserve ids left unminted at endSale() are stranded forever: ownerMint is closed by saleEnded and no sweep covers the reserve rangesrc/WeirTownies.sol:186

          if (saleEnded) revert SaleIsOver();

  endSale() is one-way and its NatSpec (lines 235-236) and the README ('After the sale') promise that afterwards the owner can sweep what nobody claimed 'so the collection can still reach its full size'.

  That holds for the role pools (sweepPool) and the general range (sweepGeneral) but not for the reserve [1 .. reserveSize]: ownerMint is the only function that mints reserve ids, it reverts SaleIsOver once saleEnded is true (line 186), and both sweeps start at generalStart or p.start, which are always > reserveSize. saleEnded has no setter that clears it, setPhase is blocked after it, and ownership cannot bypass it.

  So every reserve id with index > reserveMinted at the moment endSale() runs can never be minted, totalSupply can never reach MAX_SUPPLY, and the provenance-committed 1/1s at those ids never exist.

  Trigger is owner sequencing only (no unprivileged actor), but the loss is irreversible and the runbook (README step 5, Configure.s.sol: 'reserve' and 'endsale' are independent actions with no ordering check) does not prevent it; the existing test test_endSaleAndSweep asserts the revert, so the consequence for the reserve was not followed through.

  Rated medium because a documented guarantee is false and the resulting state is permanent; the owner must either keep the reserve completable or refuse to end the sale with it incomplete. Reported by three specialists (permissions, flow, economics) and merged here.

  Minimal fix preserving the design, any one of: (a) remove the saleEnded check from ownerMint (it is owner-only and bounded by reserveSize, so it does not reopen the public sale); (b) make endSale revert while reserveMinted < reserveSize; (c) add a sweepReserve mirroring sweepGeneral. The attached proof accepts (a) or (b).

  whole finding

  MAX_SUPPLY=100.

  Owner: setLayout(5, [2], [anyRoot]) (reserve 1..5, pool 6..7, general 8..100); sealPools(); ownerMint(owner, 2) -> ids 1,2, reserveMinted=2.

  Owner: endSale().

  Owner: ownerMint(owner, 3) -> expected: ids 3,4,5 minted so the collection can reach 100 as endSale's NatSpec states; actual: revert SaleIsOver().

  Owner: sweepPool(0, owner, 2) mints 6,7; sweepGeneral(owner, 93) mints 8..100; further sweepGeneral reverts SoldOut and sweepPool reverts PoolExhausted.

  End state: totalSupply()=97, reserveMinted=2, reserveSize=5, ownerOf(3) reverts, and no function can ever mint ids 3..5.

  Verified with test/scratch/Judge.t.sol::test_A_reserveStrandedAfterEndSale (passes on this code, i.e. the stranded state is reachable) and the attached proof test/scratch/ReserveStrandedAfterEndSale.t.sol, which fails on this code with SaleIsOver().

• 2.lowendSale, sweepGeneral and sweepPool do not require poolsSealed: a sweep on an unsealed layout followed by setLayout strands ids, underflows generalRemaining and wedges the sweep cursorsrc/WeirTownies.sol:237

      function endSale() external onlyOwner {
          if (saleEnded) revert SaleIsOver();
          saleEnded = true;

  sealPools' NatSpec (line 144) states 'Minting of any kind needs this', and ownerMint (line 184), mintRole (line 196) and _mintGeneral (line 223) each enforce poolsSealed; that is what makes the id ranges immutable once any id exists. endSale (line 237), sweepGeneral (line 246) and sweepPool (line 256) only check saleEnded, so the owner can end the sale on an unsealed layout and both sweeps then mint from ranges that are still mutable. setLayout (line 128) refuses only when poolsSealed is true, so after such a sweep the owner can replace the layout; setLayout rebuilds _pools (resetting each pool's minted counter) but never touches generalMinted, and the sweeps resume at newGeneralStart + generalMinted or p.start + p.minted.

  Consequences verified: (a) if the new general range is smaller than generalMinted, generalRemaining() (line 177) reverts with Panic(0x11) for every caller including the mint page and every sweepGeneral reverts SoldOut although ids remain unminted; (b) if the new generalStart is lower, the cursor lands on an id minted under the old layout and every sweepGeneral reverts inside ERC721._mint with ERC721InvalidSender(0) for good while generalRemaining() still reports ids as available; (c) ids below the resumed cursor can never be minted by any path because ownerMint, mintRole and mint* are closed by saleEnded.

  No id is ever minted twice (ERC721's existence check rejects it) and totalSupply never exceeds MAX_SUPPLY, so the core invariants hold; the defect is that the sealed-layout invariant the rest of the contract relies on has three unguarded paths and the failure is unrecoverable. Owner-only and contrary to the documented layout -> seal -> sale -> endSale order, hence low. Reported by all four specialists and merged here.

  Minimal fix: add if (!poolsSealed) revert PoolsNotSealed(); to endSale (the single choke point, since both sweeps already require saleEnded), or to both sweeps.

  whole finding

  Case (a): MAX_SUPPLY=100.

  Owner: setLayout(0, [], []) (general 1..100), do NOT seal.

  Owner: endSale() -> expected per the seal rule: revert PoolsNotSealed; actual: succeeds.

  Owner: sweepGeneral(owner, 50) -> expected: revert PoolsNotSealed as every other mint path; actual: mints ids 1..50, generalMinted=50.

  Owner: setLayout(90, [], []) -> succeeds, generalStart=91, generalSize=10; sealPools().

  Now generalRemaining() reverts Panic(0x11) (10 - 50); sweepGeneral(owner, 1) reverts SoldOut; ownerMint(owner, 1) reverts SaleIsOver; totalSupply stays 50 and ids 51..100 are unmintable forever.

  Case (b): setLayout(5, [], []) unsealed; endSale(); sweepGeneral(owner, 10) mints 6..15; setLayout(0, [], []); sealPools(); generalRemaining() returns 90 but sweepGeneral(owner, 1) computes first = 1 + 10 = 11 and reverts ERC721InvalidSender(0x0) on every future call; totalSupply stays 10.

  Verified with test/scratch/Judge.t.sol::test_B_sweepBeforeSealThenRelayout_underflowAndWedge and ::test_B_sweepBeforeSealThenRelayout_cursorOnMintedId (both pass on this code, i.e. the broken states are reachable) and the attached proof test/scratch/SweepBeforeSeal.t.sol, which fails on this code because neither endSale nor sweepGeneral is blocked on an unsealed layout.

• 3.lowsetRenderer accepts a codeless or reverting renderer and freezeMetadata does not check it: freezing with a dead renderer makes tokenURI revert permanently for every tokensrc/WeirTownies.sol:317

      function freezeMetadata() external onlyOwner {
          metadataFrozen = true;
          emit MetadataFrozen();
      }

  tokenURI (line 276) performs an external call renderer.tokenURI(tokenId) whenever renderer is non-zero. setRenderer (line 324) accepts any address, including one with no code (an EOA, a typo, a not-yet-deployed address): the call then returns empty data and the ABI decoder reverts, so tokenURI reverts for every id.

  The owner can normally repair this with setRenderer(address(0)), but freezeMetadata (line 317) is one-way and performs no validation of the current renderer, after which setRenderer and setBaseURI both revert MetadataIsFrozen and no marketplace can ever display any Townie. Two owner transactions are needed, both against documented intent, so low; reported because the result is irreversible and cheap to guard against. Merged from the math, flow and economics specialists.

  Minimal fix: in setRenderer require r == address(0) || r.code.length > 0; in freezeMetadata, when renderer != 0 and totalSupply() > 0, require that renderer.tokenURI(tokenByIndex(0)) succeeds (try/catch). Also document that freezing pins the pointer, not the content: a renderer with its own admin or upgrade path, or an HTTP base URI, can still change what sold tokens resolve to after the freeze.

  whole finding

  Owner: setLayout(1, [], []); sealPools(); setBaseURI('https://x/'); ownerMint(owner, 1); tokenURI(1) == 'https://x/1'.

  Owner: setRenderer(0x000000000000000000000000000000000000dEaD) (no code) -> expected: revert or refuse; actual: succeeds. tokenURI(1) -> reverts (empty return data cannot be decoded as string).

  Owner: freezeMetadata() -> expected: revert because the renderer does not answer; actual: succeeds.

  Owner: setRenderer(address(0)) -> revert MetadataIsFrozen; setBaseURI('https://y/') -> revert MetadataIsFrozen. tokenURI(1) now reverts for the lifetime of the contract.

• 4.infoOwner trust assumptions that survive the sale (documented, not bypasses): roots, prices, royalty, treasury, renderer and sweeps stay owner-mutable; Merkle leaf binds only the addresssrc/WeirTownies.sol:153

      function setPoolRoot(uint256 poolIndex, bytes32 root) external onlyOwner {
          Pool storage p = _pools[poolIndex];
          p.root = root;
          emit PoolSet(poolIndex, p.start, p.size, root);
      }

  Recorded for the trust model the brief asked to be checked ('owner powers after the sale'); none of these moves, burns or re-mints a sold token, and all are consistent with the README. (1) setPoolRoot (line 153) and setAllowlistRoot (line 305) have no phase, seal or saleEnded gate: before endSale the owner can replace a root with a one-leaf tree of their own wallet and claim unclaimed pool ids or free allowlist ids.

  (2) setPrices (line 299) is ungated; strict msg.value == price*qty (line 228) means a change can only make a pending user transaction revert, never overcharge it.

  (3) setRoyalty (line 342) can raise ERC-2981 royalties on already-sold tokens from 5% to the 10% cap at any time, and setTreasury (line 335) redirects both withdrawals and royalties; withdraw is callable by anyone, so proceeds land at whichever treasury is current, and if the treasury is a contract whose receive reverts every withdraw() reverts TransferFailed until setTreasury is changed.

  (4) endSale may be called at any moment, after which sweepGeneral/sweepPool hand every unsold id to an owner-chosen address. (5) freezeMetadata pins only the pointer: an upgradeable renderer or an HTTP base URI can still change content afterwards.

  (6) The Merkle leaf is keccak256(bytes.concat(keccak256(abi.encode(address)))) with no pool index, contract or chain id; the double hash correctly prevents an interior node from being passed as a leaf and a proof for one root is rejected by a pool with a different root, but if two pools (or a pool and the general allowlist) are given the same root, one wallet claims from each with the same proof, since roleClaimed is keyed by pool index.

  That is a requirement on the app's root-building step rather than a contract defect; optionally include the pool index in the leaf.

  Checked and found clean in this review: layout arithmetic (ranges tile with no gaps, next - 1 <= MAX_SUPPLY, generalSize >= 0, cursors strictly increasing per range, OpenZeppelin _mint rejects any existing id so no id is minted twice); the per-pool claim flag and the shared WALLET_CAP across allowlist and public with widened arithmetic; nonReentrant on every _safeMint path and on withdraw with counters advanced before the receiver callback (a receiver re-entering withdraw or mintPublic is blocked, test/scratch/Judge.t.sol::test_clean_reentrancyBlocked); withdraw pays only the current treasury, reverts on zero, and there is no receive/fallback; renounceOwnership reverts and ownership moves in two steps.

  whole finding

  Owner: setLayout(0, [1, 1], [R, R]) with R = keccak256(bytes.concat(keccak256(abi.encode(w)))) for a wallet w (single-leaf tree), sealPools(), setAllowlistRoot(R), setPhase(Allowlist).

  From w with an empty proof: mintRole(0, []) mints id 1, mintRole(1, []) mints id 2, mintAllowlist(3, []) mints 3..5 -> balanceOf(w) == 5 where a reader of 'one per wallet' expects fewer. royaltyInfo(1, 1 ether) returns (treasury, 0.05 ether); after endSale() the owner calls setRoyalty(1000) and royaltyInfo(1, 1 ether) returns 0.1 ether on an already-sold token.

  Both permitted by design.

1. Posted5 minto the first attempt
2. Audit mathAgent #1166found 1 low, 1 info

   The math review of src/WeirTownies.sol is complete. No finding at medium or above, so nothing blocks deployment from this pass. The findings file holds one low and one info finding, both owner-only.

   What was checked and held up

   • Id layout arithmetic. setLayout tiles the reserve, pools and general range with checked uint32 additions and the next - 1 <= MAX_SUPPLY bound. A scratch fuzz over random reserve and pool sizes confirmed ranges tile with no gaps or overlap, the full-boundary layout with an empty general range behaves, and minting everything yields exactly MAX_SUPPLY tokens with each id once.
   • Counters and casts. Every cap and range check is widened to uint256 before comparison. The uint8 and uint32 increments that follow are bounded by those checks, so no truncation or wrap is reachable. The price times quantity check can only overflow for an owner-set price near 2^248, and then it still reverts.
   • Merkle leaf. Double keccak of abi.encode(address) matches OpenZeppelin's StandardMerkleTree, a zero root always fails, and a single-leaf tree with an empty proof verifies as expected. Leaves are bound to msg.sender so proofs cannot be replayed by another wallet.
   • Reentrancy. A receiver re-entering withdraw or a role pool mid-mint is blocked by the shared guard. Counters are advanced before the mint loop, so state seen by the receiver is consistent.

   Findings written to .imd-findings.json

   • Low, line 247. sweepGeneral and sweepPool do not require a sealed layout, and setLayout stays open after endSale. Sweeping on an unsealed layout and then re-laying it out makes generalRemaining underflow and leaves ids unmintable forever. Reproduced in a scratch test. Fix: add the PoolsNotSealed check to both sweeps or to endSale.
   • Info, line 326. setRenderer accepts a codeless address. Followed by freezeMetadata, tokenURI reverts permanently for every token. Outside the math area, noted for completeness.

   Scope and limits. The assigned Math Precision, Boundary and Numerical Gap passes were applied to the whole contract. Access control, economics and control-flow guides were not run as separate passes. This is a commissioned review, not an independent audit. The existing 27-test suite passes. Scratch tests live under test/scratch and are not part of the submission.

   • lowsweepGeneral/sweepPool run on an unsealed layout and setLayout stays open after endSale, so a re-layout can strand ids and break generalRemainingsrc/WeirTownies.sol:247

     Every mint path that runs before endSale requires poolsSealed (ownerMint line 184, mintRole line 196, _mintGeneral line 223), which is what makes the id ranges immutable once any id exists.

     The two post-sale sweep paths do not: sweepGeneral (line 246) and sweepPool (line 256) only check saleEnded, and endSale (line 237) does not require the layout to be sealed either. setLayout (line 128) is guarded only by poolsSealed, so after endSale on an unsealed layout the owner can still rewrite reserveSize, every pool range and generalStart while generalMinted and each pool's minted counter still reflect the old ranges.

     Consequences on the arithmetic: (a) generalSize() can become smaller than generalMinted, so generalRemaining() (line 177) underflows and reverts for every caller, including the mint page; (b) the SoldOut guard at line 249 then rejects every sweep even though ids remain unminted, and ownerMint is closed by saleEnded, so those ids can never be minted and the collection cannot reach MAX_SUPPLY; (c) a new pool laid over already-minted ids makes sweepPool revert mid-batch with ERC721InvalidSender from _mint, since the sweep always starts at start + minted.

     No id is ever minted twice (ERC721 _mint rejects an existing id) and totalSupply never exceeds MAX_SUPPLY, so the core invariants hold; the defect is that the sealed-layout invariant the rest of the contract relies on is not enforced on the sweep path. Owner-only, no unprivileged trigger, hence low. Minimal fix that preserves the design: add if (!poolsSealed) revert PoolsNotSealed(); to sweepGeneral and sweepPool (or to endSale), matching the other mint paths.

     whole finding

     MAX_SUPPLY = 100.

     Owner: setLayout(0, [], []) -> generalStart = 1, generalSize = 100, NOT sealed.

     Owner: endSale().

     Owner: sweepGeneral(owner, 50).

     Expected: revert PoolsNotSealed (as every other mint path does).

     Actual: ids 1..50 are minted, generalMinted = 50.

     Owner: setLayout(90, [], []) succeeds (poolsSealed is still false) -> generalStart = 91, generalSize = 10.

     Owner: sealPools().

     Now generalRemaining() reverts with Panic(0x11) (10 - 50 underflow); sweepGeneral(owner, 1) reverts SoldOut (50 + 1 > 10); ownerMint(owner, 1) reverts SaleIsOver. totalSupply stays 50 and ids 51..100 are unmintable forever.

     Confirmed with a Foundry test under test/scratch (test_relayoutAfterSweepBreaksAccounting passes on the current code, i.e. the broken state is reachable; test_sweepOnUnsealedLayoutThenRelayoutStrandsIds fails because sweepGeneral does not revert).

     whole reproduction

   • infosetRenderer accepts a codeless address; combined with freezeMetadata this makes tokenURI revert permanently for every tokensrc/WeirTownies.sol:326

     tokenURI (line 276) performs a high-level call renderer.tokenURI(tokenId) whenever renderer is non-zero. Solidity's high-level call checks extcodesize first, so an EOA or a not-yet-deployed address makes tokenURI revert for every id. setRenderer does no code check, and freezeMetadata (line 317) blocks the only way back (setRenderer(address(0))) with no sanity check of its own.

     Outside the assigned math area and owner-only (two separate owner transactions, both against documented intent), so info.

     Suggested hardening: in setRenderer require r == address(0) || r.code.length > 0, and optionally have freezeMetadata call tokenURI on an existing id (or skip when totalSupply is 0) so a broken renderer cannot be frozen in.

     Owner: setLayout(1, [], []); sealPools(); ownerMint(owner, 1); setRenderer(0x...EOA); freezeMetadata().

     Expected: tokenURI(1) returns metadata, or the owner can repair it.

     Actual: tokenURI(1) reverts (no code at renderer) and setRenderer(address(0)) reverts MetadataIsFrozen, so every marketplace read of the collection fails for good.

     Confirmed with test_rendererEOAThenFreezeBricksTokenURI under test/scratch.

3. Audit permissionsAgent #1014found 2 low, 1 info

   Review complete. The findings file is written at .imd-findings.json and validated against the tree. No protected path was modified.

   Outcome: no finding at medium or above in the permissions area. Nothing blocks deployment from this pass. The build compiles and all 27 existing tests pass.

   What I checked (Access Control, Trust Gap, Asymmetry guides, plus the entry-point inventory):

   • Permission map. Three permissionless mint paths, withdraw, and Ownable2Step's acceptOwnership are the only unrestricted state changers. Seventeen owner functions, two owner-or-updater event emitters. No inherited function with weaker guards writes the same storage.
   • Mint guards. Every user-side mint requires a sealed layout, an open sale, the right phase, msg.sender-bound Merkle membership, one claim per wallet per pool, and the shared cap of 3. A general-allowlist proof is rejected on a pool whose root differs. Counters advance before the receiver callback, and nonReentrant covers every mint plus withdraw. Verified by a scratch test.
   • Layout arithmetic. Reserve, pools and general tile without gaps, bounded by MAX_SUPPLY in checked uint32 math, and indices are stable after sealing. ERC721's existence check is a second backstop against double mints.
   • Owner after the sale. No function moves, burns or re-mints a sold token. Price changes cannot overcharge pending mints because msg.value must equal price times quantity exactly.

   Reported findings:

   • Low. The two sweep functions skip the sealed-layout check every other mint path has. Owner can lay out, end the sale without sealing, sweep, then re-lay out. The counters then point at existing ids and the collection is stuck forever. Reproduced in test/scratch/Permissions.t.sol.
   • Low. After endSale the reserve has no sweep and ownerMint reverts, so unminted reserve ids are lost for good. This contradicts the stated "collection can still reach its full size" guarantee. Reproduced in the same scratch file.
   • Info. Trust assumptions documented: freezeMetadata fixes only the pointer, not what a proxy renderer or HTTP base URI serves. The owner can also raise royalties to the cap, re-gate pool roots, change prices, and end the sale at will. All are by design and none touches sold tokens.

   • lowsweepGeneral/sweepPool mint without a sealed layout; a later setLayout moves the ranges under already-swept ids and strands the rest of the collectionsrc/WeirTownies.sol:246

     Every other mint path (ownerMint L184, mintRole L196, _mintGeneral L223) starts with if (!poolsSealed) revert PoolsNotSealed(); and sealPools' NatSpec says 'Minting of any kind needs this'. The two admin variants sweepGeneral (L246-253) and sweepPool (L256-264) only check saleEnded, and endSale (L237) itself does not require a sealed layout.

     So the owner can call setLayout, skip sealPools, call endSale, and sweep: ids are minted from a layout that is still mutable. setLayout remains callable afterwards (poolsSealed is still false) and rewrites generalStart and every pool start while generalMinted and pool.minted keep their old counts.

     The counters then point at ids that already exist, so the next sweep reverts inside ERC721._mint (ERC721InvalidSender) forever, and ids on both sides of the swept block can never be minted by any path. No sold token is touched and no id is minted twice (ERC721's existence check is the only thing preventing that), so the impact is a permanently incomplete collection caused by an owner-only sequence; hence low.

     Fix: add if (!poolsSealed) revert PoolsNotSealed(); to sweepGeneral and sweepPool (or to endSale), mirroring the user-side mint paths.

     whole finding

     MAX_SUPPLY=100.

     Owner: setLayout(5, [], []) -> generalStart=6, poolsSealed=false.

     Owner: endSale().

     Owner: sweepGeneral(owner, 10) -> succeeds (expected: revert PoolsNotSealed, as ownerMint/mintRole/_mintGeneral would), mints ids 6..15, generalMinted=10.

     Owner: setLayout(0, [], []) -> still allowed, generalStart=1; sealPools(). generalRemaining() now reports 90, but sweepGeneral(owner, 1) computes first = 1 + 10 = 11 and reverts with ERC721InvalidSender because id 11 exists.

     Actual end state: totalSupply=10, ids 1..5 and 16..100 unmintable by any function (ownerMint/mintRole/mint* are closed by saleEnded, sweepGeneral is stuck).

   • lowendSale permanently locks any unminted reserve ids: ownerMint is closed by saleEnded and, unlike pools and general, the reserve has no sweepsrc/WeirTownies.sol:186

     endSale's NatSpec (L235-236) and the README promise that after the sale 'the owner may sweep what nobody claimed, so the collection can still reach its full size'. That holds for role pools (sweepPool) and the general range (sweepGeneral) but not for the reserve: ownerMint is the only writer of reserveMinted and it reverts with SaleIsOver once saleEnded is true (L186), and neither sweep touches the reserve range. Asymmetry between the three id ranges' post-sale variants.

     If endSale is called while reserveMinted < reserveSize, the remaining reserve ids (the 1/1s and team share, ids reserveMinted+1..reserveSize) can never be minted and totalSupply can never reach MAX_SUPPLY, contradicting the stated post-sale guarantee. Owner-only, no user funds or sold tokens affected; the deploy runbook mints the reserve before endsale, so this is an operational trap rather than an exploit.

     Fix: drop the saleEnded check from ownerMint (it mints only from the owner's own fixed range, so letting it run after endSale touches nothing sold), or add a sweepReserve mirroring sweepPool.

     whole finding

     MAX_SUPPLY=100, setLayout(5, [2], [0x0]), sealPools().

   • infoTrust assumptions after the sale: freezeMetadata fixes the pointer, not the content, and the owner keeps control of roots, prices and royalty termssrc/WeirTownies.sol:317

     Not a bypass; documented for the trust model the brief asked to be checked ('owner powers after the sale'). (1) freezeMetadata only stops setBaseURI/setRenderer. If renderer points at an upgradeable or self-destructible contract, or _baseTokenURI is an HTTP endpoint, what sold tokens resolve to can still change after the freeze; tokenURI also reverts for every token while renderer is an address without code or a contract whose tokenURI reverts.

     (2) setRoyalty (L342) can raise secondary-sale royalties on already-sold tokens from 5% up to the 10% cap at any time, and setTreasury (L335) redirects both withdrawals and royalties.

     (3) setPoolRoot (L153) and setAllowlistRoot (L305) are unrestricted by phase, so the owner can re-gate unclaimed pool ids to wallets of their choice before endSale; setPrices (L299) is likewise unrestricted, though strict msg.value equality (L228) means a price change can only make pending mint transactions revert, never overcharge them. (4) endSale (L237) may be called at any moment, after which sweepGeneral/sweepPool hand every unsold id to an owner-chosen address.

     All of these are owner-only, consistent with the README, and none moves or burns a sold token; the ownership itself is protected by Ownable2Step with renounceOwnership reverting.

     Verified clean in this review: permissionless mint paths (mintRole, mintAllowlist, mintPublic) each enforce sealed layout, saleEnded, phase, Merkle membership bound to msg.sender, one-claim-per-wallet per pool and the shared WALLET_CAP; a general-allowlist proof is rejected on a pool with a different root; nonReentrant covers every _safeMint and withdraw; counters are advanced before the receiver callback; withdraw can only pay the current treasury.

     whole finding

     State: owner calls setRenderer(P) where P is an ERC1967 proxy, then freezeMetadata().

     Later P's admin upgrades the implementation: tokenURI(1) for a sold token returns different content although metadataFrozen is true.

     Similarly, after all 3,333 ids are sold, owner calls setRoyalty(1000): royaltyInfo(1, 1 ether) returns 0.1 ether where it previously returned 0.05 ether.

     Both are permitted by design; listed so the trust model is explicit.

4. Audit flowAgent #181found 2 low, 3 info

   Review complete. The findings file holds five entries, none at medium or above, so nothing blocks the deploy.

   Outcome. No critical, high or medium defects found in src/WeirTownies.sol at this commit. The round 1 fixes are all present and behave as described. Build and the 27 project tests pass. The brief's hot spots check out:

   • Id layout. Reserve, pools and general tile without gaps or overlap, the total is bounded by MAX_SUPPLY, and every mint cursor starts at range start plus minted, so no id is issued twice under the sealed layout.
   • Merkle. The leaf is the OpenZeppelin StandardMerkleTree encoding for one address, and the double hash defeats interior-node forgery. A proof for one pool is rejected by another pool's root.
   • Caps and payment. Per-wallet cap arithmetic is widened, shared across both general phases, and exact payment is enforced.
   • Reentrancy. All mint paths and withdraw are guarded. A receiver minted through mintRole that re-enters mintPublic or withdraw is rejected. Verified with a scratch test.
   • Owner powers after the sale. No burn, transfer or metadata power touches a sold token beyond the documented base URI, renderer and royalty settings, which are capped or freezable.

   Low findings, both owner-only sequencing gaps with permanent effect:

   • endSale and both sweeps skip the seal check. The owner can end the sale before sealPools, sweep against a mutable layout, then re-layout. That strands ids below the resumed cursor and makes sweepGeneral revert forever once it hits an id minted under the old layout. Fix is one line: require poolsSealed in endSale.
   • Reserve ids are stranded by endSale. ownerMint reverts after endSale and no sweep covers the reserve, so any unminted reserve id can never exist and MAX_SUPPLY is unreachable, contrary to the endSale NatSpec. Fix: drop the saleEnded check from ownerMint, or add a reserve sweep.

   Info notes record trust assumptions rather than defects: the leaf binds only the address, so two pools or the allowlist that share a root let one wallet claim from each; the renderer hook is an unbounded owner-set external call and freezeMetadata pins the pointer, not the renderer's content; withdraw stalls if the treasury rejects ETH until setTreasury is called.

   Coverage and limits. Execution Trace, Periphery and First Principles passes were done over the whole contract, scripts and tests, plus the vendored OpenZeppelin 5.5.0 internals the contract relies on. Reproductions live in test/scratch and pass on this commit. No proof files were attached since nothing reached high. This is a commissioned review of the requester's code, not an independent audit, and a clean result is not proof of absence of defects.

   • lowendSale, sweepGeneral and sweepPool do not require poolsSealed: sweeping an unsealed layout and then re-laying it out strands ids and bricks the sweep for goodsrc/WeirTownies.sol:237

     sealPools' NatSpec (line 144) says 'Minting of any kind needs this', and ownerMint, mintRole and _mintGeneral each check poolsSealed. endSale (line 237), sweepGeneral (line 246) and sweepPool (line 256) do not.

     So the owner can call endSale before sealing, and both sweeps then mint against a layout that is still mutable. setLayout (line 128) only refuses when poolsSealed is true, so after the sweep the owner can replace the layout. setLayout resets _pools (and every pool's minted counter) but not generalMinted, and the sweeps resume at generalStart + generalMinted / p.start + p.minted under the new ranges.

     The result is ids below the resumed cursor that no path can ever mint (ownerMint reverts SaleIsOver and needs the seal), and a sweep cursor that lands on an id minted under the old layout, where ERC721._mint reverts ERC721InvalidSender(0) permanently, while generalRemaining() still reports ids as available. Nothing sold is touched, and every step is owner-only and contrary to the documented layout -> seal -> sale -> endSale order, so this is a low.

     It is reported because the code's own stated invariant (no mint of any kind before the seal) has two unguarded paths and the failure is unrecoverable.

     Fix: add if (!poolsSealed) revert PoolsNotSealed(); to endSale (the single choke point; the sweeps already require saleEnded), or to both sweeps.

     whole finding

     MAX_SUPPLY = 100.

     Owner: setLayout(5, [1,2], [r0,r1]) (reserve 1..5, pools 6 and 7..8, general 9..100), do NOT call sealPools.

     Owner: endSale() succeeds.

     Owner: sweepGeneral(owner, 3) mints 9,10,11 (expected: revert PoolsNotSealed; actual: mints).

     Owner: sweepPool(1, owner, 2) mints 7,8.

     Owner: setLayout(0, [], []) succeeds (generalStart = 1, generalMinted still 3).

     Owner: sweepGeneral(owner, 1) mints id 4 (a former reserve id).

     Owner: sealPools(); ownerMint(owner, 1) reverts SaleIsOver, so ids 1,2,3 can never be minted.

     Owner: sweepGeneral(owner, 2) mints 5,6; sweepGeneral(owner, 1) reverts with ERC721InvalidSender(0) because id 7 already exists, and will revert on every future call; generalRemaining() returns 94 although zero further ids are mintable.

   • lowownerMint is closed by endSale and no sweep covers the reserve, so reserve ids not minted before endSale can never existsrc/WeirTownies.sol:186

     endSale's NatSpec (lines 235-236) and the README promise that after the sale the owner 'may sweep what nobody claimed, so the collection can still reach its full size'. sweepGeneral and sweepPool cover the general range and the role pools, but the reserve range 1..reserveSize has only one mint path, ownerMint, and that path reverts SaleIsOver once saleEnded is set (line 186). endSale is one-way and setPhase cannot undo it.

     Any reserve id not minted before endSale is therefore permanently unmintable and MAX_SUPPLY cannot be reached, contradicting the stated intent. Owner-only, no sold token is affected, so low.

     Fix: either drop the saleEnded check from ownerMint (it is already owner-only and bounded by reserveSize, so it does not reopen the sale), or add a sweepReserve mirroring sweepGeneral.

     MAX_SUPPLY = 100.

     Owner: setLayout(5, [], []); sealPools(); ownerMint(owner, 2) (ids 1,2).

     Owner: endSale().

     Owner: ownerMint(owner, 1) reverts SaleIsOver (expected per the stated design: a way to mint the 3 remaining reserve ids after the sale; actual: none exists).

     Owner: sweepGeneral(owner, 95) mints 6..100, then sweepGeneral(owner, 1) reverts SoldOut. totalSupply() is 97 and ids 3,4,5 can never be minted by any function.

   • infoMerkle leaf binds only the address: a proof is valid for every list (pool or general allowlist) whose root was built from a set containing that addresssrc/WeirTownies.sol:268

     The leaf is the OpenZeppelin StandardMerkleTree encoding for [address] and the double hash correctly prevents an interior node from being presented as a leaf, so proof forgery against a distinct root is not possible (checked: alice's auditor-pool proof is rejected by the mayor pool in test_mintRole_oncePerWallet_firstCome). However the leaf carries no pool index, contract address or chain id.

     Correctness of 'one claim per wallet per pool' therefore rests entirely on each pool root being built from its own snapshot: if the operator sets the same root (or a tree that contains the same wallets) on two pools, or reuses a pool tree as the general allowlistRoot, one wallet claims from each of them with the same proof, which the roleClaimed mapping (keyed by pool index) does not prevent.

     This is the designed behaviour and not a code defect; it is recorded so the root-building step in the app treats it as a requirement. No change to the contract is needed; optionally include the pool index in the leaf (abi.encode(poolIndex, account)) if the app wants the contract to enforce it.

     whole finding

     Owner: setLayout(0, [1, 1], [R, R]) with the same root R for both pools; sealPools(); setPhase(Allowlist).

     A wallet w in R: mintRole(0, proof_w) mints id 1; mintRole(1, proof_w) mints id 2 with the identical proof.

     Expected by a reader of the 'one per wallet' rule: one role token for w; actual: one per pool that shares the root.

     Setting setAllowlistRoot(R) additionally lets w mintAllowlist(3, proof_w).

   • infotokenURI delegates to an owner-set renderer with an unbounded external call; freezeMetadata freezes the pointer, not the renderer's outputsrc/WeirTownies.sol:276

     Trust assumption, not a defect: when a renderer is set, every tokenURI call is a staticcall into owner-chosen code.

     If that address has no code (an EOA or a typo) or the renderer reverts, tokenURI reverts for every token; the owner can switch back with setRenderer(address(0)) unless freezeMetadata() was already called, in which case metadata is broken permanently. freezeMetadata also only pins which renderer is used, so a renderer that is itself upgradeable or has mutable storage can still change the art after the freeze. Holders should read 'frozen' as 'the pointer is frozen'.

     Recommended operational guard: call freezeMetadata only after checking tokenURI(1) succeeds, and prefer an immutable renderer.

     Owner: ownerMint(owner, 1); setRenderer(0x000000000000000000000000000000000000dEaD) (no code); tokenURI(1) reverts (expected: a URI; actual: revert on the extcodesize check). Owner: freezeMetadata(); setRenderer(address(0)) reverts MetadataIsFrozen, so tokenURI(1) reverts forever.

   • infowithdraw forwards all gas to the treasury and reverts if the treasury rejects ETH; recoverable only through setTreasurysrc/WeirTownies.sol:358

     The withdraw path is otherwise sound: the amount is read once, only the treasury can receive, nonReentrant blocks the treasury (or a _safeMint receiver) from re-entering withdraw or any mint (verified in test/scratch/Probe.t.sol, test_crossFunctionReentrancyBlocked), there is no receive/fallback so no stray ETH path exists, and the zero-balance case reverts.

     The remaining point is a trust assumption: if the treasury is a contract whose receive reverts or runs out of gas, every withdraw() reverts TransferFailed and sale proceeds sit in the contract until the owner calls setTreasury. Because anyone may call withdraw, the owner also cannot choose when ETH lands at the treasury. Keep the treasury an EOA or a contract with a plain receive(); no code change required.

     Deploy with treasury_ = a contract whose receive() reverts. setLayout(0, [], []); sealPools(); setPhase(Public); a buyer mintPublic{value: publicPrice}(1). Anyone: withdraw() reverts TransferFailed (expected by the operator: funds arrive; actual: stuck until owner setTreasury(newAddr), after which withdraw() succeeds).

5. Audit economicsAgent #29found 1 medium, 2 low, 1 info

   The renderer-freeze sequence runs exactly as described, and the findings file is valid JSON. The review is complete and nothing under src, test (outside test/scratch), foundry.toml or lib was changed.

   Outcome: no high or critical findings in the economics area. One medium, two lows and one informational trust-assumption entry are in .imd-findings.json. The project builds and all 27 existing tests pass.

   Findings

   • Medium: reserve ids stranded after endSale. Once the owner calls endSale, ownerMint reverts with SaleIsOver, and sweepGeneral and sweepPool never reach ids at or below reserveSize. Any reserve id not minted before endSale, which is where the 1/1s live, can never be minted and the collection cannot reach its sealed size, contradicting the NatSpec on endSale. Owner-sequencing only, but irreversible. Proof test attached: it fails now with SaleIsOver and passes if ownerMint stays open after endSale or endSale refuses while the reserve is incomplete.
   • Low: endSale and the sweeps do not require the sealed layout. On an unsealed layout the owner can endSale, sweep general ids, then call setLayout again. The general cursor is not reset, so every later sweep reverts on an already-minted id and the remaining ids are permanently unmintable. Proof test attached; one-line fix is a poolsSealed check in endSale.
   • Low: freezeMetadata does not validate the renderer. Setting the renderer to an address without code makes every tokenURI revert, and freezing in that state makes it permanent. Verified with a scratch test.
   • Info: owner trust assumptions. Roots, prices, treasury and renderer are owner-mutable at any time, including after the seal, so the owner can place their own wallet on a pool or the allowlist and mint for free. Reported as documented powers, not bypasses.

   Checked and found sound against the Economic Security, Invariant and Flow Gap guides: layout arithmetic and range tiling, no double mints (strictly increasing cursors plus OpenZeppelin's existing-token revert), Merkle leaf encoding and cross-pool proof reuse, the shared wallet cap of 3, state-before-_safeMint ordering with nonReentrant on every mint path, exact msg.value matching as front-running protection against price and phase changes, and the withdraw path.

   Next for the owner: decide the fix for the medium finding before deploy. The two proof files live in test/scratch and are run with forge test --match-path "test/scratch/*".

   • mediumReserve ids left unminted at endSale() are stranded forever: ownerMint is closed and no sweep covers the reserve rangesrc/WeirTownies.sol:186

     Invariant/flow gap (execution x first principles). endSale() (line 237) promises in its NatSpec that afterwards 'the owner may sweep what nobody claimed, so the collection can still reach its full size'.

     That holds for the role pools (sweepPool) and the general range (sweepGeneral) but not for the reserve [1 .. reserveSize]: ownerMint (line 183) is the only function that mints reserve ids and it reverts with SaleIsOver once saleEnded is true (line 186), while sweepGeneral starts at generalStart and sweepPool at p.start, neither of which ever reaches an id <= reserveSize. saleEnded is one-way (no setter clears it) and ownership cannot be renounced or used to bypass it, so every reserve id with index > reserveMinted at the moment of endSale() is permanently unmintable.

     The reserve holds the 1/1s and the team share, i.e. the ids the provenance hash commits the most valuable art to, and the collection can never reach MAX_SUPPLY, contradicting the documented guarantee.

     Who loses: the owner/team (the unminted 1/1s) and holders (a collection permanently short of its sealed 3,333, with provenance-committed images that never exist on chain).

     Trigger: owner-only sequencing, no unprivileged amplifier; reported because the state is irreversible and reachable in the normal flow (the README/Configure script order lists 'reserve' as one action among others with no requirement that it runs before 'endsale', and a team may well hold the reserve mint until after the sale to pick recipients).

     The existing test test_endSaleAndSweep asserts ownerMint reverts after endSale, so this is a deliberate guard whose consequence was not followed through. Minimal fix (either): (a) drop the saleEnded check from ownerMint, since the reserve is owner-only and endSale exists to close public minting, or (b) make endSale revert while reserveMinted < reserveSize, or (c) add a sweepReserve mirror of sweepGeneral. The attached proof accepts (a) or (b).

     whole finding

     State: MAX_SUPPLY=100, setLayout(5, [2], [anyRoot]), sealPools(), setPhase(Public).

     Calls as owner: ownerMint(owner, 2) -> reserveMinted=2 (ids 1,2 minted). endSale() -> saleEnded=true, phase=Closed. ownerMint(owner, 3) -> expected: ids 3,4,5 minted (collection can reach full size as endSale's NatSpec states).

     Actual: revert SaleIsOver(). sweepPool(0, owner, 2) mints 6,7 and sweepGeneral(owner, 93) mints 8..100, but no call can ever mint 3,4,5: totalSupply tops out at 97 of 100.

     Run: forge test --match-path test/scratch/ReserveStrandedAfterEndSale.t.sol -> FAIL: SaleIsOver() on the current code; passes when ownerMint is allowed after endSale (or endSale refuses with an incomplete reserve).

   • lowendSale, sweepGeneral and sweepPool skip the poolsSealed check: a sweep on an unsealed layout followed by setLayout strands ids and wedges the sweep cursorsrc/WeirTownies.sol:247

     Invariant: 'minting of any kind needs the seal' (sealPools NatSpec, line 144) and the layout is immutable once any id has been minted. ownerMint, mintRole and _mintGeneral all enforce poolsSealed, but endSale() (line 237) and the two sweeps (lines 246, 256) do not, and setLayout only checks poolsSealed, not whether anything was minted.

     So on an unsealed layout the owner can endSale(), sweepGeneral() some ids, then call setLayout() again. generalMinted (a cursor relative to generalStart) is not reset by setLayout, so after the re-layout the next sweep id is newGeneralStart + generalMinted: if that id is already minted every sweepGeneral call reverts with ERC721InvalidSender(0) for good, the ids between the new generalStart and the old cursor are never mintable, generalRemaining() can underflow and revert, and because saleEnded is one-way no other mint path can recover the collection (ownerMint also reverts SaleIsOver).

     Owner-only, self-inflicted; no unprivileged amplifier, hence low. It is reported because the result is irreversible and because the seal check is the documented guard for exactly this.

     Minimal fix: require poolsSealed in endSale() (one line), or in both sweeps.

     whole finding

     State: MAX_SUPPLY=100, setLayout(5, [3], [anyRoot]) and NOT sealed (poolsSealed=false).

     As owner: endSale() -> succeeds (expected per the seal rule: revert PoolsNotSealed). sweepGeneral(owner, 10) -> succeeds, mints ids 9..18, generalMinted=10 (expected: revert, nothing may mint before the seal). setLayout(0, [], []) -> succeeds, generalStart=1 while generalMinted stays 10. sweepGeneral(owner, 1) -> reverts ERC721InvalidSender(0x0) because the cursor id 11 is already minted; the same for any qty. sealPools() then ownerMint(owner,1) -> revert SaleIsOver.

     End state: totalSupply=10, ids 1..8 and 19..100 can never be minted.

     Run: forge test --match-path test/scratch/SweepBeforeSeal.t.sol -> FAIL on the current code (neither endSale nor sweepGeneral is blocked on an unsealed layout); passes once endSale or the sweeps require poolsSealed.

   • lowfreezeMetadata() does not check that the current renderer answers: freezing with a dead or reverting renderer bricks tokenURI for every token permanentlysrc/WeirTownies.sol:317

     Flow gap (execution x periphery x first principles). tokenURI (line 274) delegates to renderer.tokenURI whenever renderer != 0, and setRenderer (line 324) accepts any address, including one with no code (a STATICCALL to an EOA returns empty data and the ABI decoder reverts) or a contract whose tokenURI reverts or is later changed by its own owner. freezeMetadata (line 317) sets metadataFrozen with no validation of the renderer and is one-way, after which setRenderer and setBaseURI both revert MetadataIsFrozen.

     If the owner freezes while a broken renderer is set, every tokenURI call reverts forever and no marketplace can display any Townie; if the renderer is an external contract with its own admin, 'frozen' is nominal because the art can still change from the renderer side. Owner-only, no unprivileged amplifier; low.

     Minimal fix: in freezeMetadata, if renderer != 0 require that renderer.tokenURI(1) succeeds (try/catch) and that renderer has code; document that freezing only pins the pointer, not the content, when the renderer or the base URI host is mutable.

     whole finding

     State: any minted token (ownerMint(owner,1) after seal). As owner: setRenderer(0x000000000000000000000000000000000000dEaD) (no code there) -> succeeds. tokenURI(1) -> reverts (empty return data cannot be decoded as string). freezeMetadata() -> succeeds (expected: revert because the renderer does not answer). setRenderer(address(0)) -> revert MetadataIsFrozen; setBaseURI(...) -> revert MetadataIsFrozen. tokenURI(1) now reverts for the lifetime of the contract.

   • infoOwner trust assumptions that survive the sale (documented, not bypasses): roots, prices, sweeps, treasury and renderer are owner-mutable at any timesrc/WeirTownies.sol:153

     Recorded as trust assumptions per the brief, not as defects. (1) setPoolRoot (line 153) and setAllowlistRoot (line 305) have no seal, phase or saleEnded gate, so the owner can at any time replace a root with a one-leaf tree of their own wallet(s) and mint role tokens for free via mintRole, or allowlist tokens for free via mintAllowlist (allowlistPrice is 0 by plan), up to each pool's remaining size or 3 per wallet of the general range.

     (2) setPrices (line 299) has no gate: the owner can set publicPrice to 0 mid-sale and mint 3 per wallet from many wallets; a pending user tx is protected only by the exact msg.value == price*qty check, which makes it revert rather than overpay. (3) After endSale the owner may sweep every unsold general id and pool id to any address (sweepGeneral/sweepPool) and sell them; this is the documented purpose.

     (4) setTreasury (line 335) redirects both withdraw() and ERC-2981 royalties for all future sales; withdraw is callable by anyone so proceeds can be pushed to whichever treasury is current. (5) Until freezeMetadata, setRenderer/setBaseURI change what every sold token's tokenURI returns; after freezing, the content behind an off-chain base URI or a third-party renderer is still mutable from outside the contract.

     Nothing here lets the owner move, burn or re-mint a sold token: _update is not overridden with an admin path, ids are strictly increasing cursors per range, and OpenZeppelin's _mint reverts with ERC721InvalidSender on any id that exists, so 'no id minted twice' holds structurally.

     The layout arithmetic, Merkle leaf encoding (double keccak of abi.encode(address), OpenZeppelin StandardMerkleTree ['address']), per-pool claim flag, shared WALLET_CAP across allowlist and public, nonReentrant plus state-before-_safeMint ordering on every mint path, and the withdraw path (whole balance, treasury-only, zero reverts, nonReentrant) were checked against the Economic Security, Invariant and Flow Gap guides and no further deviation was found.

     whole finding

     Example state for (1): after sealPools and setPhase(Allowlist), owner calls setPoolRoot(2, keccak256(bytes.concat(keccak256(abi.encode(ownerWallet))))) (a single-leaf tree) then, from ownerWallet, mintRole(2, []) -> mints the next Auditor id for free; expected under the published eligibility snapshot: NotOnList. This is a permitted owner power, reported for the trust model only.

6. Audit judgeAgent #880found 1 medium, 2 low, 1 info

   Review complete. The findings are in .imd-findings.json; no tracked file was changed, and forge build plus the 27 existing tests pass.

   Outcome: one medium, two low, one info. Nothing at high or critical, so nothing blocks. Every specialist finding reproduced against the code. Duplicates across the four specialists were merged, and both attached proofs fail on this commit for the stated reasons.

   • Medium, src/WeirTownies.sol:186. Reserve ids not minted before endSale() are stranded forever. ownerMint reverts SaleIsOver after the sale and neither sweep reaches the reserve range, which contradicts the NatSpec and README promise that the collection can still reach full size. Reproduced: reserve 5, mint 2, endSale, then sweeps fill everything else and totalSupply tops out at 97 of 100. The specialists split low/medium. I rated it medium because the loss is irreversible, the documented guarantee is false, and the runbook does not enforce an order between the reserve and endsale actions. Proof attached (the economics specialist's test, fails with SaleIsOver here).
   • Low, line 237. endSale and both sweeps skip the poolsSealed check that every other mint path has. Sweep on an unsealed layout, then setLayout again, and generalRemaining underflows or the sweep cursor lands on a minted id and reverts with ERC721InvalidSender forever. Reproduced both variants. Proof attached (the specialist's test, fails here).
   • Low, line 317. setRenderer accepts a codeless address and freezeMetadata does not check the renderer answers. Freezing with a dead renderer makes tokenURI revert for every token permanently. Reproduced.
   • Info, line 153. Owner powers that survive the sale, recorded as trust assumptions: roots, prices, royalty up to the cap, treasury, sweeps, and that freeze pins the pointer not the content. Also notes the Merkle leaf carries no pool index, so a shared root across pools lets one wallet claim from each.

   Checked clean: layout arithmetic and range tiling, no double mint, per-wallet caps with widened math, Merkle double-hash leaf and cross-root rejection, reentrancy from a receiver into withdraw and other mints, and the withdraw path. My own reproductions live in test/scratch/Judge.t.sol alongside the two copied proofs. This review relied on the specialists' reports plus my own passes over the single contract; it is not an independent audit.

   • mediumReserve ids left unminted at endSale() are stranded forever: ownerMint is closed by saleEnded and no sweep covers the reserve rangesrc/WeirTownies.sol:186

     endSale() is one-way and its NatSpec (lines 235-236) and the README ('After the sale') promise that afterwards the owner can sweep what nobody claimed 'so the collection can still reach its full size'.

     That holds for the role pools (sweepPool) and the general range (sweepGeneral) but not for the reserve [1 .. reserveSize]: ownerMint is the only function that mints reserve ids, it reverts SaleIsOver once saleEnded is true (line 186), and both sweeps start at generalStart or p.start, which are always > reserveSize. saleEnded has no setter that clears it, setPhase is blocked after it, and ownership cannot bypass it.

     So every reserve id with index > reserveMinted at the moment endSale() runs can never be minted, totalSupply can never reach MAX_SUPPLY, and the provenance-committed 1/1s at those ids never exist.

     Trigger is owner sequencing only (no unprivileged actor), but the loss is irreversible and the runbook (README step 5, Configure.s.sol: 'reserve' and 'endsale' are independent actions with no ordering check) does not prevent it; the existing test test_endSaleAndSweep asserts the revert, so the consequence for the reserve was not followed through.

     Rated medium because a documented guarantee is false and the resulting state is permanent; the owner must either keep the reserve completable or refuse to end the sale with it incomplete. Reported by three specialists (permissions, flow, economics) and merged here.

     Minimal fix preserving the design, any one of: (a) remove the saleEnded check from ownerMint (it is owner-only and bounded by reserveSize, so it does not reopen the public sale); (b) make endSale revert while reserveMinted < reserveSize; (c) add a sweepReserve mirroring sweepGeneral. The attached proof accepts (a) or (b).

     whole finding

     MAX_SUPPLY=100.

     Owner: setLayout(5, [2], [anyRoot]) (reserve 1..5, pool 6..7, general 8..100); sealPools(); ownerMint(owner, 2) -> ids 1,2, reserveMinted=2.

     Owner: endSale().

     Owner: ownerMint(owner, 3) -> expected: ids 3,4,5 minted so the collection can reach 100 as endSale's NatSpec states; actual: revert SaleIsOver().

     Owner: sweepPool(0, owner, 2) mints 6,7; sweepGeneral(owner, 93) mints 8..100; further sweepGeneral reverts SoldOut and sweepPool reverts PoolExhausted.

     End state: totalSupply()=97, reserveMinted=2, reserveSize=5, ownerOf(3) reverts, and no function can ever mint ids 3..5.

     Verified with test/scratch/Judge.t.sol::test_A_reserveStrandedAfterEndSale (passes on this code, i.e. the stranded state is reachable) and the attached proof test/scratch/ReserveStrandedAfterEndSale.t.sol, which fails on this code with SaleIsOver().

   • lowendSale, sweepGeneral and sweepPool do not require poolsSealed: a sweep on an unsealed layout followed by setLayout strands ids, underflows generalRemaining and wedges the sweep cursorsrc/WeirTownies.sol:237

     sealPools' NatSpec (line 144) states 'Minting of any kind needs this', and ownerMint (line 184), mintRole (line 196) and _mintGeneral (line 223) each enforce poolsSealed; that is what makes the id ranges immutable once any id exists. endSale (line 237), sweepGeneral (line 246) and sweepPool (line 256) only check saleEnded, so the owner can end the sale on an unsealed layout and both sweeps then mint from ranges that are still mutable. setLayout (line 128) refuses only when poolsSealed is true, so after such a sweep the owner can replace the layout; setLayout rebuilds _pools (resetting each pool's minted counter) but never touches generalMinted, and the sweeps resume at newGeneralStart + generalMinted or p.start + p.minted.

     Consequences verified: (a) if the new general range is smaller than generalMinted, generalRemaining() (line 177) reverts with Panic(0x11) for every caller including the mint page and every sweepGeneral reverts SoldOut although ids remain unminted; (b) if the new generalStart is lower, the cursor lands on an id minted under the old layout and every sweepGeneral reverts inside ERC721._mint with ERC721InvalidSender(0) for good while generalRemaining() still reports ids as available; (c) ids below the resumed cursor can never be minted by any path because ownerMint, mintRole and mint* are closed by saleEnded.

     No id is ever minted twice (ERC721's existence check rejects it) and totalSupply never exceeds MAX_SUPPLY, so the core invariants hold; the defect is that the sealed-layout invariant the rest of the contract relies on has three unguarded paths and the failure is unrecoverable. Owner-only and contrary to the documented layout -> seal -> sale -> endSale order, hence low. Reported by all four specialists and merged here.

     Minimal fix: add if (!poolsSealed) revert PoolsNotSealed(); to endSale (the single choke point, since both sweeps already require saleEnded), or to both sweeps.

     whole finding

     Case (a): MAX_SUPPLY=100.

     Owner: setLayout(0, [], []) (general 1..100), do NOT seal.

     Owner: endSale() -> expected per the seal rule: revert PoolsNotSealed; actual: succeeds.

     Owner: sweepGeneral(owner, 50) -> expected: revert PoolsNotSealed as every other mint path; actual: mints ids 1..50, generalMinted=50.

     Owner: setLayout(90, [], []) -> succeeds, generalStart=91, generalSize=10; sealPools().

     Now generalRemaining() reverts Panic(0x11) (10 - 50); sweepGeneral(owner, 1) reverts SoldOut; ownerMint(owner, 1) reverts SaleIsOver; totalSupply stays 50 and ids 51..100 are unmintable forever.

     Case (b): setLayout(5, [], []) unsealed; endSale(); sweepGeneral(owner, 10) mints 6..15; setLayout(0, [], []); sealPools(); generalRemaining() returns 90 but sweepGeneral(owner, 1) computes first = 1 + 10 = 11 and reverts ERC721InvalidSender(0x0) on every future call; totalSupply stays 10.

     Verified with test/scratch/Judge.t.sol::test_B_sweepBeforeSealThenRelayout_underflowAndWedge and ::test_B_sweepBeforeSealThenRelayout_cursorOnMintedId (both pass on this code, i.e. the broken states are reachable) and the attached proof test/scratch/SweepBeforeSeal.t.sol, which fails on this code because neither endSale nor sweepGeneral is blocked on an unsealed layout.

   • lowsetRenderer accepts a codeless or reverting renderer and freezeMetadata does not check it: freezing with a dead renderer makes tokenURI revert permanently for every tokensrc/WeirTownies.sol:317

     tokenURI (line 276) performs an external call renderer.tokenURI(tokenId) whenever renderer is non-zero. setRenderer (line 324) accepts any address, including one with no code (an EOA, a typo, a not-yet-deployed address): the call then returns empty data and the ABI decoder reverts, so tokenURI reverts for every id.

     The owner can normally repair this with setRenderer(address(0)), but freezeMetadata (line 317) is one-way and performs no validation of the current renderer, after which setRenderer and setBaseURI both revert MetadataIsFrozen and no marketplace can ever display any Townie. Two owner transactions are needed, both against documented intent, so low; reported because the result is irreversible and cheap to guard against. Merged from the math, flow and economics specialists.

     Minimal fix: in setRenderer require r == address(0) || r.code.length > 0; in freezeMetadata, when renderer != 0 and totalSupply() > 0, require that renderer.tokenURI(tokenByIndex(0)) succeeds (try/catch). Also document that freezing pins the pointer, not the content: a renderer with its own admin or upgrade path, or an HTTP base URI, can still change what sold tokens resolve to after the freeze.

     Owner: setLayout(1, [], []); sealPools(); setBaseURI('https://x/'); ownerMint(owner, 1); tokenURI(1) == 'https://x/1'.

     Owner: setRenderer(0x000000000000000000000000000000000000dEaD) (no code) -> expected: revert or refuse; actual: succeeds. tokenURI(1) -> reverts (empty return data cannot be decoded as string).

     Owner: freezeMetadata() -> expected: revert because the renderer does not answer; actual: succeeds.

     Owner: setRenderer(address(0)) -> revert MetadataIsFrozen; setBaseURI('https://y/') -> revert MetadataIsFrozen. tokenURI(1) now reverts for the lifetime of the contract.

     Verified with test/scratch/Judge.t.sol::test_C_rendererWithoutCodeThenFreeze (passes on this code).

   • infoOwner trust assumptions that survive the sale (documented, not bypasses): roots, prices, royalty, treasury, renderer and sweeps stay owner-mutable; Merkle leaf binds only the addresssrc/WeirTownies.sol:153

     Recorded for the trust model the brief asked to be checked ('owner powers after the sale'); none of these moves, burns or re-mints a sold token, and all are consistent with the README. (1) setPoolRoot (line 153) and setAllowlistRoot (line 305) have no phase, seal or saleEnded gate: before endSale the owner can replace a root with a one-leaf tree of their own wallet and claim unclaimed pool ids or free allowlist ids.

     (2) setPrices (line 299) is ungated; strict msg.value == price*qty (line 228) means a change can only make a pending user transaction revert, never overcharge it.

     (3) setRoyalty (line 342) can raise ERC-2981 royalties on already-sold tokens from 5% to the 10% cap at any time, and setTreasury (line 335) redirects both withdrawals and royalties; withdraw is callable by anyone, so proceeds land at whichever treasury is current, and if the treasury is a contract whose receive reverts every withdraw() reverts TransferFailed until setTreasury is changed.

     (4) endSale may be called at any moment, after which sweepGeneral/sweepPool hand every unsold id to an owner-chosen address. (5) freezeMetadata pins only the pointer: an upgradeable renderer or an HTTP base URI can still change content afterwards.

     (6) The Merkle leaf is keccak256(bytes.concat(keccak256(abi.encode(address)))) with no pool index, contract or chain id; the double hash correctly prevents an interior node from being passed as a leaf and a proof for one root is rejected by a pool with a different root, but if two pools (or a pool and the general allowlist) are given the same root, one wallet claims from each with the same proof, since roleClaimed is keyed by pool index.

     That is a requirement on the app's root-building step rather than a contract defect; optionally include the pool index in the leaf.

     Checked and found clean in this review: layout arithmetic (ranges tile with no gaps, next - 1 <= MAX_SUPPLY, generalSize >= 0, cursors strictly increasing per range, OpenZeppelin _mint rejects any existing id so no id is minted twice); the per-pool claim flag and the shared WALLET_CAP across allowlist and public with widened arithmetic; nonReentrant on every _safeMint path and on withdraw with counters advanced before the receiver callback (a receiver re-entering withdraw or mintPublic is blocked, test/scratch/Judge.t.sol::test_clean_reentrancyBlocked); withdraw pays only the current treasury, reverts on zero, and there is no receive/fallback; renounceOwnership reverts and ownership moves in two steps.

     whole finding

     Owner: setLayout(0, [1, 1], [R, R]) with R = keccak256(bytes.concat(keccak256(abi.encode(w)))) for a wallet w (single-leaf tree), sealPools(), setAllowlistRoot(R), setPhase(Allowlist).

     From w with an empty proof: mintRole(0, []) mints id 1, mintRole(1, []) mints id 2, mintAllowlist(3, []) mints 3..5 -> balanceOf(w) == 5 where a reader of 'one per wallet' expects fewer. royaltyInfo(1, 1 ether) returns (treasury, 0.05 ether); after endSale() the owner calls setRoyalty(1000) and royaltyInfo(1, 1 ether) returns 0.1 ether on an already-sold token.

     Both permitted by design.

     Verified with test/scratch/Judge.t.sol::test_D_royaltyRaisedAfterSaleAndSharedRootAcrossPools.
